    In re: Rivers Dev. Act 250 Appeal         }     Docket No. 68-3-07 Vtec
    }
    Decision on the Merits
    These appeals arise out of applications by Rivers Development, LLC (“Rivers”) to
    develop and operate a rock quarry and crushed rock processing facility on a 93± acre parcel off
    of Vermont Route 100B in the Town of Moretown. In Docket No. 7-1-05 Vtec, Rivers appealed
    a decision of the Town of Moretown Development Review Board dated December 10, 2004. 1 In
    Docket No. 68-3-07 Vtec, Rivers appealed a decision of the District #5 Environmental
    Commission (“District Commission”) dated January 19, 2007. 2
    Appellant Rivers has been assisted in these consolidated proceedings by its Attorneys,
    James A. Caffry and Christopher J. Nordle. The Town of Moretown, its Planning Commission,
    and its School Board (hereinafter collectively referred to as “Town”) were active participants in
    these consolidated appeals and were assisted by Town Attorneys Ronald A. Shems and Geoffrey
    H. Hand.
    A number of neighbors and Town residents entered their appearances in one or both of
    these consolidated appeals. As a consequence of the various motions to intervene, dismiss one
    or more parties, or otherwise determine party status, the Court issued Entry Orders on July 3,
    2007, and February 20, 2008; the Court attached a spreadsheet, with hand-written modifications,
    to its February 20, 2008 Entry Order that identified the individuals who sought and retained party
    1
    At the request of Applicant Rivers, this initial appeal was placed on inactive status, pending Rivers’ submission of
    an Act 250 permit application and possible appeal to this Court. See Entry Order on Motion for Stay, dated April 4,
    2005. Once the appeal of the Act 250 proceedings was filed with this Court, these appeals were consolidated and
    the stay of the municipal appeal was lifted. See Entry Order of October 22, 2007.
    2
    Rivers also responded to the District Commission’s January 19, 2007 negative findings on Act 250 criteria 1(a)
    and 10 (conformance with town plan) by filing a motion to alter with the District Commission. With the exception
    of two minor corrections of misstatements, the District Commission denied Rivers’ motion to alter by way of its
    Memorandum of Decision dated March 14, 2007.
    -1-
    status in these appeals and, in the instance of the Act 250 application appeal, a list of the Act 250
    criteria under which each party retained status. See 10 V.S.A. § 6086(a). A copy of that
    modified spreadsheet is attached to this Decision and incorporated herein by reference. These
    individuals are hereinafter referred to as “Neighbors.”
    Some of these Neighbors, as noted on the attached spreadsheet, have been assisted in
    these appeals by Attorneys David Grayck and Zachary K. Griefen. While not represented by
    counsel, neighbors Arthur and Linda Hendrickson also played active roles in the pretrial
    proceedings and merits hearing.
    The Vermont Agency of Natural Resources (“ANR”) was first assisted in these
    proceedings by Attorney Aaron D. Adler, then by Attorney Michael R. Steeves, and finally by
    Attorney Judith L. Dillon. The Land Use Panel of the Vermont Natural Resources Board was
    provided with informational notice of the Act 250 appeal proceedings, but did not play an active
    role in these appeals.
    The Town filed cross-appeals in both matters, as did the Neighbors represented by
    Attorneys Grayck and Griefen, joined by Mr. and Mrs. Hendrickson.                   Their respective
    Statements of Questions on cross-appeal, as clarified on January 25, 2008, and as modified by
    orders of this Court, provide the jurisdictional limits of their respective cross-appeals.
    Rivers’ proposal to develop this quarry has engendered strong opinions, both in favor of
    and in opposition to its development. The municipal appeal generated forty-seven pretrial
    motions; the Act 250 appeal generated thirty-nine pre-trial motions. These motions caused the
    Court to issue an equivalent number of decisions or entry orders, nearly twenty of which
    included a substantive analysis of legal issues presented by the parties. Where the Court has
    been asked to revisit those legal issues in this Merits Decision, we have made reference, where
    appropriate, to those pretrial decisions and entry orders.
    The consolidated appeals were the subject of a de novo merits hearing that spanned
    seventeen calendar days. Prior to the first day of trial (February 12, 2008), Applicant Rivers
    requested that the trial be bifurcated so that issues related to possible impacts from blasting and
    alleged air and water issues could be addressed at a later date. The Town, Neighbors, and other
    parties objected to this trial-bifurcation request, particularly on the grounds of the resulting added
    expense and delay, but given Rivers’ explanation of an evolution of the treatment of water and
    -2-
    air issues, the Court granted Rivers’ request. See Entry Order dated January 18, 2008, and the
    parties’ Stipulation and Court Order of February 5, 2008.
    The first phase of the trial was completed on February 22, 2008. The second phase of the
    trial commenced on December 8, 2008, and was completed on January 14, 2009. The parties
    requested the opportunity to make post-trial filings of proposed findings of fact and conclusions
    of law, and to thereafter have an opportunity to respond to the filings of other parties. This
    process of post-trial filings was completed on April 28, 2009, after which this matter became ripe
    for the Court’s consideration.
    The Court has reviewed the nearly 1,000 pages of post-trial filings submitted by the
    parties, as well as the evidence admitted at trial, other relevant filings, and the Court’s own trial
    notes, which together take up four bankers’ boxes. Even in light of this volume, the undersigned
    has allowed these consolidated appeals to remain under advisement for far longer than was
    reasonable, thereby causing a substantial delay in the current resolution of these appeals. The
    undersigned regrets this error, and has attempted to craft a complete Decision on the Merits, so
    as to not contribute to further delay in these proceedings.
    The Court conducted two site visits with the parties, which included walks within the
    project site, once while the natural vegetation provided some screening on the project site, and
    once when the natural vegetation had fallen. The first site visit was on September 24, 2007, and
    the second on November 19, 2007, both in accordance with a “Site Visit Protocol” initially
    agreed to by the parties and adopted by the Court, pursuant to its Entry Order of August 23,
    2007, but which was the subject of disputes and addressed in the Court’s Entry Orders of
    September 18, 2007, and November 16, 2007. During the site visits, the Court also visited the
    Village of Moretown, the Moretown Elementary School (including its two front classrooms that
    were the subject of discussion during trial), several traffic intersections between Vermont Route
    100B and Town highways, and several locations along Moretown Mountain Road, Moretown
    Commons Road, the Town road commonly known as Old Route 100, and Vermont Route 100B.
    The proposed quarry site could be seen from several of the areas visited during the Court’s site
    visits; it was suggested during trial that the proposed quarry operations would be heard from
    these areas as well. The Court also visited the residence of Mr. and Mrs. Hendricks and the sites
    where the Sainsbury and McMullin horse riding facilities have been operated. These site visits
    -3-
    provided the Court with a beneficial context within which to receive the evidence admitted at
    trial.
    Based upon the evidence admitted at trial, including that which was put into context by
    the site visits, and after having determined the appropriate weight and credibility to afford such
    evidence, the Court does hereby render the following Findings of Fact and Conclusions of Law:
    Findings of Fact and Conclusions of Law
    First, an explanation of the format of this Merits Decision. This Court has generally
    followed a format of decision writing that is similar to other trial courts and our Supreme Court:
    that is, to begin with a full recitation of the facts and then to proceed to a discussion of the legal
    issues. Conversely, Act 250 district environmental commissions follow a slightly different
    format, whereby factual findings and legal conclusions were completed on each applicable Act
    250 criterion before then moving on to the next applicable criterion. We experiment here with a
    variation on the latter decision format, similar to that of the district commissions and that which
    the parties here have followed in their post-trial filings. Our Findings are cumulative; all
    discussion of legal conclusions relies upon all of the Findings stated in the prior sections of this
    Decision, so as to avoid the necessity of repeating previously stated Findings.
    As we have often stated, our jurisdiction does not encompass all issues raised by an
    appealed application, but rather is limited to the factual and legal issues preserved for our review
    by the parties. In re Jolley Assoc., 
    2006 VT 132
    , ¶ 9 (quoting In re Garen, 
    174 Vt. 151
    , 156
    (2002)); see also V.R.E.C.P. 5 (f) (“The appellant may not raise any questions on the appeal not
    presented in the statement [of questions] as filed . . . .”). A review of the Statement of Questions
    filed by Appellant Rivers and Cross-Appellants Town and Neighbors, as well as the various
    pretrial decisions and entry orders that addressed multiple challenges to those appellate issues,
    shows that certain Act 250 criteria, as well as correlating provisions of the 2003 Zoning
    Regulations for the Town of Moretown, Vermont (“Zoning Regulations”) remain at issue in
    these appeals. Those Act 250 criteria are:
     1 (air and water), 1(B), 1(D), 1(E), 1(F), 2, 3, and 4 (all of which are addressed
    below under our heading “II. Air, Water, and Erosion Issues”);
     5 (addressed under the heading below “III. Traffic”);
     6, 7, 9(H), 9(J), and 9(K) (addressed under the heading below “IV. Economic
    Impacts”);
    -4-
     8 (addressed under the heading below “V. Aesthetics, Area’s Natural Beauty, and
    Historic Sites”);
     8(A) (addressed under the heading below “VI. Necessary Wildlife Habitat and
    Endangered Species”);
     9(E) (addressed under the heading below “VII. Extraction of Earth Resources”);
     9(K) (addressed under the heading “VIII. Impact Upon Public Investments”); and
     10 (addressed under the heading below “IX. Conformance with Town Plan”).
    The factual and legal issues preserved for our review under the Zoning Regulations are
    reviewed under the analogous Act 250 criteria headings. Our first sub-heading concerns an
    overview of the proposed quarry, the neighborhood surrounding it, and other affected areas in
    Town.
    I. General Findings of Fact.
    A.      The quarry and its general description.
    1.      Rivers owns a parcel of undeveloped land containing 93± acres. Access to the Rivers
    parcel is off of Vermont Route 100B; this access is located about two and a half miles north of
    the Village of Moretown and about four miles south of the intersection between Vermont Routes
    2 and 100B, which is between the interchanges known as Exits 9 and 10 to Interstate 89. Rivers
    proposes to develop its rock quarry and crushed-rock-processing facility on its parcel along
    Route 100B.
    2.      Rivers filed its application with the Town of Moretown Development Review Board
    (“DRB”) on May 17, 2004. This application sought conditional use approval and a zoning
    permit for the proposed quarry.
    3.      Rivers subsequently filed an application for an Act 250 state land use permit for its
    proposed quarry and crushed-rock-processing facility.      Its Act 250 permit application was
    received by the District Commission on October 15, 2005.
    4.      The Rivers parcel is generally wooded with a mixture of hardwoods and softwoods. The
    only improvements to the parcel are internal woods roads, generally established during historical
    timber cuts.
    5.      Rivers proposes to disturb about nineteen acres generally located in the center of the
    ninety-three acre parcel.   The quarry itself will encompass about seventeen acres; clearing
    around the brim of the quarry will encompass about two additional acres. This additional
    -5-
    clearing will be done to accommodate a rough woods road around the brim of the quarry that
    will be used for quarry access by drilling and other equipment.
    6.       To prepare the site, Rivers would clear phases of the quarry site of all trees and
    vegetative cover, strip and store the topsoil on site for future use, and remove and store the
    overburden, 3 all to expose the rock for excavation, drilling, and blasting.
    7.       Excavation is proposed to occur in six phases, as depicted in Rivers’ final amended site
    plan (Exhibit R-4(E)). 4 Rivers asserted that it could not guarantee that these operational phases
    would occur in numerical order, as decisions would have to be made on site as to the proper
    sequence of phases once the excavation work at the quarry began.
    8.       Rivers further asserted that once the quarry is operating and an individual phase was cut,
    cleared, and its topsoil stockpiled, rock would be excavated within each phase. The topography
    of the site ranges widely, particularly due to rock outcroppings. While some rock may initially
    be harvested through simple excavation, Rivers represents that its quarry will largely rely upon
    drilling and blasting, the plan for which is addressed in more detail below in Section VII. Once a
    blast occurs, rock would be collected and stockpiled on site. Rock that is of an appropriate size
    will be stockpiled on site for later sale. Rock that the blasting operation leaves of a size too big
    for market will be processed on site through the use of a diesel-powered rock crusher and
    screener. This processed rock will also then be stockpiled on site for future sale.
    9.       Fuel and blasting materials and supplies will only be brought on site when needed; no
    such products will be stored on site.
    10.      Equipment operating within the quarry will be limited to the following: one hydraulic
    rock drill; one excavator; one bucket loader; one rock crusher; one triple-deck crushed rock
    screener; one yard truck, with water tank, to be used for dust suppression; one backhoe; and
    miscellaneous small hand and power tools as needed. Rivers will also use several large haul
    trucks to deliver processed rock from the quarry site to its customers’ job sites, and will allow
    customers to use their own haul trucks to receive and transport processed rock that they purchase
    from the Rivers quarry.
    3
    “Overburden” refers to the earthen material and loose rock that is between the topsoil and the rock ledge.
    4
    Rivers caused its site plan to be revised and amended on several occasions, including during the first phase of the
    merits hearing. This revision process caused much consternation for the other parties and the Court. Rivers asserted
    that its revisions were made for clarification purposes and to address criticisms offered by the opposing parties. The
    Court ultimately allowed the admission of the final revised site plans: Exhibit R-4(E) (pages 1–7).
    -6-
    11.    Drilling, blasting, crushing, and excavation at the quarry will operate on a seasonal basis,
    from April 15 through December 15 of each year. Thus, the quarry will be in operation during
    some months when vegetative cover is thin or no longer present. During its operational season,
    the quarry will operate Monday through Friday between 7:00 AM and 5:00 PM, not including
    state and federal holidays. Blasting will be limited to Monday through Friday, between 10:00
    AM and 4:00 PM.
    12.    Quarry employees will also be on site during its operational season on Saturdays from
    7:00 AM until noon.          Off-season sale of stockpiled material may only occur during its
    conventional operational hours, and only upon the prior written approval of the ANR Department
    of Fish and Wildlife.
    13.    The annual rock production will occur within 150 to 170 operating days.              Rivers
    estimates that its drilling equipment will run about sixty days during each of its operating
    seasons, in preparation for the estimated twelve blasts per operational year. The rock crusher
    and screener will need to be operated between seventy-five and ninety days each year to process
    the blasted rock.
    14.    The quarry will have a maximum annual extraction rate of 75,000 cubic yards of rock
    product. Estimates of the available rock on site have lead Rivers to propose that the quarry will
    operate for approximately thirty-three years.
    15.    This extraction rate will generate a maximum of fifty-four loaded haul trucks per day
    (i.e., 108 one-way truck trips) and up to twenty one-way trips of other vehicles per day by quarry
    employees, customers, and delivery drivers.
    16.    All rock extracted and processed at Rivers’ quarry will be available for sale to retail and
    wholesale customers and contractors. The crushed stone products will include large landscaping
    stones, rip rap stones for river and highway bank construction and fortification, various
    dimensional stone, and smaller stone for drainage and road construction projects.
    17.    Retail and wholesale customers will be allowed to visit the Rivers quarry site to inspect
    and purchase stone. Rivers will also offer to haul processed rock to its customers’ job sites,
    using its own haul trucks.
    18.    Processed rock will be loaded onto haul trucks belonging to Rivers or its customers by
    use of a front-end loader depositing the rock into the truck bed.
    -7-
    19.     Employees and customers will access the quarry site by a 1,400-foot access road from
    Route 100B. This access road is currently a minimally improved woods road last used for
    logging the site. To satisfy the traffic generated by the quarry, the access road will need to be
    improved, including widening in many areas and improvement with gravel and stone that will
    come from the initial quarry operations. In addition, removal of earthen material and stone along
    the westerly side of Route 100B, north of the quarry access road, will be necessary to meet the
    minimum site distances required by the Vermont Agency of Transportation (“VTrans”) for state
    highways. This excavation along the edge of Route 100B may require blasting of ledge, as may
    some areas of the access-road improvements.
    20.     Both the Zoning Regulations and the Town of Moretown Town Plan (“Town Plan”) that
    are applicable to the pending applications locate the Rivers property in the Agricultural-
    Residential Zoning District (“Ag-Res District”). 5              Due to the dates on which Rivers filed
    complete applications, the Town Plan applicable to these proceedings is that which was adopted
    on August 27, 2002. The Town Plan identifies a portion of the Rivers property as being within
    the Route 100B/Mad River Corridor. While portions of the quarry may also be viewed from the
    Route 100B/Mad River Corridor, the quarry itself is outside the 300-foot limits of the Corridor,
    as measured from the edge of Route 100B. The best estimate is that the area to be disturbed for
    quarry operations is about 760 feet from the edge of Route 100B.
    21.     Rivers proposes to reclaim the quarry site in phases as rock extraction is completed in
    each phase. Because of the steep and varied topography of the quarry site, blasting will result in
    benches left on the rock walls of the quarry. Each bench will be about fifteen feet in height and
    width/depth. The highest benched wall will be on the northwestern face of the quarry, where the
    area rises most steeply. This area will include about fourteen benches and rise about 210 feet
    from the quarry floor.
    5
    The Court determined the Zoning Regulations last amended in 2003 and Town Plan last amended in 2002 were
    applicable to the Rivers’ applications in its Corrected Decision on Rivers’ Initial Motions, filed January 18, 2008
    (copy available at http://www.vermontjudiciary.org/GTC/Environmental/ENVCRT%20Opinions/Rivers%20
    Deveopment%20LLC,%207-1-05%20Vtec.pdf) (The Court’s web page incorrectly lists the filing date of this
    decision as February 5, 2008.). The parties and the Court sometimes referred to the applicable Zoning Regulations
    as the Zoning Regulations “adopted on March 7, 2000,” because the subsequent amendment, adopted in 2003, is not
    applicable to rock quarries or the Ag-Res District. Id. at 4.
    -8-
    22.    Rivers proposes to use the stockpiled topsoil to cover the quarry floor and some of the
    horizontal faces of the rock benches, then to seed and mulch these areas and to allow other bench
    areas and faces to regenerate vegetation over time by unassisted natural conditions.
    B.     The surrounding neighborhood.
    23.    The Ag-Res District and other areas surrounding the general area of the quarry are thinly
    developed; where development has occurred, it is mostly with single-family residences. No
    other sand, gravel, or rock quarries were identified within the immediate area or in this region of
    Moretown, nor were any commercial developments or light or heavy industrial uses identified in
    this region of Town.
    24.    Four horse farms are also located in the vicinity of the Rivers quarry; all are located on
    the opposite side of Route 100B. Several of the horse farms have indoor and outdoor riding
    arenas, riding trails, and pastures, where they provide riding lessons and boarding. Two of these
    horse farms, owned by the Sainsbury and McMullin families, are adjacent to the Rivers parcel,
    across Route 100B.
    25.    Route 100B traverses this region of Town in a general north/south direction. This state
    highway is identified as a rural collector highway. It begins to the south of Moretown Village at
    a junction with Vermont Route 100, which travels to the west of Route 100B in a more direct
    north/south direction. Route 100B is easterly of Route 100; Route 100B provides an alternate,
    southerly access to Vermont Route 2 and Interstate 89.
    26.    Route 100 travels the length of Vermont, from the border with Massachusetts along the
    central portion of southern Vermont to the border with Canada along the western edge of
    northern Vermont. Route 100B is an approximately six and a half mile spur off of this rural
    highway. Route 100B generally follows the Mad River as it travels from its junction with the
    Winooski River, south and through Moretown Village.
    27.    Traveling along Route 100B and that portion of the Mad River represents one of the most
    beautiful highway and river traverses in our State. The views are mostly of sparsely settled
    valleys and hillsides, with recreation outlets along the river bank. While Route 100B is often
    used as access for visitors traveling from the south along Interstate 89 to the Mad River Glen and
    Sugarbush Mountain Ski Resorts, located to the south of Moretown and off of Route 100 in the
    Towns of Waitsfield and Warren, the character of Route 100B is more rural and sparsely settled
    than the areas along Route 100 that provide a gateway to those resorts.
    -9-
    28.    Route 100B also serves as a bike riding corridor for both individual riders and
    participants in commercial bike-riding tours. The roadway of Route 100B is particularly well
    suited for bicycle riding once the traveler leaves the Village section of Route 100B. North of the
    Village, and until Route 100B ends at its junction with Vermont Route 2, the road shoulders are
    wide and many portions of the roadway are gently rolling. The views for a bicyclist along this
    section of Route 100B are picturesque, even breathtaking, especially as the highway travels
    closely to the banks of the Mad River, which lies just east of Route 100B.
    C.     Moretown Village.
    29.    Route 100B travels through Moretown Village; it represents the Village’s Main Street.
    The highway through the Village is narrow and lacks shoulders. The Town Offices, U.S. Post
    Office, Moretown General Store, Town Library, and Town Elementary School are all within the
    Village limits; some buildings are set very close to the paved limits of the highway.
    30.    While there are sidewalks along a short portion of the highway, as it travels through the
    Village, the sidewalks are in poor condition. There are many sections within the Village where
    there are no sidewalks, thereby necessitating that pedestrians sometimes use the highway to walk
    from one Village building to the next. Where there are sidewalks in the Village, they are in
    deplorable condition; they often have no curbing, or curbing that is much deteriorated. It is often
    difficult to distinguish between the sidewalk and the travel lane of the highway.
    31.    The Town did not provide a satisfactory explanation for why it has allowed these
    sidewalks to deteriorate so greatly, even as the Town offered examples of injuries suffered by
    pedestrians as they traveled along these sidewalks, which on several occasions caused
    pedestrians to fall onto the highway roadway.
    32.    Moretown Village appears as a typical small, beautiful, quaint Vermont village. School
    children and other individuals walk along its Main Street, traveling between its school, library,
    town offices, and athletic fields behind the town buildings. Single-family homes line Main
    Street, and some are quite close to the paved edges of the Street in the lower and upper parts of
    the Village.
    33.    As one travels south of the Village along Route 100B, the roadway narrows even further
    to a bridge that crosses the Mad River. There is a roadway pull-off just south of the bridge that
    provides access to a swimming hole along the western river bank. Travel along this portion of
    Route 100B can be difficult for vehicles, bicyclists, and pedestrians.
    -10-
    34.     Traveling further south, the Route 100B roadway widens, particularly after an
    intersection with a town highway that was recently improved. Some of this intersection’s
    improvements required blasting along the roadway, which left exposed rock surfaces near the
    intersection.
    35.     While testimony at trial referenced two rock quarries in Town, one of which is located at
    the Town Landfill on particularly steep slopes, there was no evidence of quarries or light or
    heavy industrial developments in the vicinity of the Rivers quarry site or Moretown Village.
    II. Air, Water, and Erosion Issues.
    A.      Air Pollution (Act 250 criterion 1 and Zoning Regulations § 4.10(B)(4)).
    36.     Diesel engines will power most all of the quarry equipment; these diesel engines will
    emit some polluting particles into the air. Haul trucks using the quarry will also emit pollution
    particles into the air from their diesel engines, both while the trucks are operating in the quarry
    and while traveling along Route 100B to their destinations. Each engine will be fitted with
    exhaust mufflers in accordance with federal regulations.
    37.     The improved access road will be a gravel road bed. As trucks and other vehicles travel
    over this access road, dust and small stones will be thrown up into the air. Rivers proposes to
    use water from the on-site detention pond to spray and suppress dust along the access road.
    Rivers also proposes to apply calcium chloride to the access road and other site areas where the
    haul trucks will travel, so as to further assist in the suppression of dust.
    38.     Water sprayed from the yard truck will also be used to suppress dust on the quarry floor
    and on the stockpiles of topsoil and overburden.
    39.     The process of drilling into the rock ledge to prepare it for a blast requires a series of
    holes to be drilled into the rock. Holes will be drilled in a row somewhat parallel to the rock
    face. Additional rows of drilled holes will be aligned further back from the rock face. These
    rows are sometimes aligned in a slight “V” formation so that the blast will direct the blasted rock
    into itself, so as to further assist in the break up of the rock. This orientation and procedure for
    blasting will cause dust, small rock, and sometimes larger rock to fly into the air.
    40.     The drilling and crushing of rock creates dust. Rivers proposes to also suppress this
    operational dust by way of dust collection and water misting, either through a collector or mister
    attached to the drilling and crushing apparatuses or by water sprayed from the yard truck.
    -11-
    41.    Rivers had not determined as of the time of trial whether it will employ its own rock
    crusher or that of an outside contractor. If and when it uses its own rock crusher, Rivers
    represents that its crusher will have a maximum product output of 100 tons per hour (“tph”) of
    rock product and an internal combustion engine with a rating of no greater than 450 brake
    horsepower. Such a crusher will not exceed the operational limits for a crusher that may be
    operated without an air pollution control permit issued by the ANR Department of
    Environmental Conservation Air Pollution Control Division. See Vermont Air Pollution Control
    Regulations §§ 5-401(5) and 5-501.
    42.    If Rivers employed an outside contractor to operate its on-site rock crushing operation, it
    would not allow its contractor to operate a crusher on site that ran in excess of the Vermont Air
    Pollution Control Regulations maximums (150 tph output or over 450 brake horsepower) without
    first securing an air pollution control permit from the DEC Air Pollution Control Division.
    During trial, Rivers noted that an area contractor that leases out its crusher already has secured a
    DEC Air Pollution Control permit and may be available to crush rock at the Rivers quarry.
    43.    Rivers will cause all diesel equipment used at the quarry site to be outfitted with required
    air emission control devices, including exhaust mufflers and catalytic converters. The haul
    trucks used at the quarry site and traveling outside the quarry that are subject to federal
    regulations will comply with applicable federal emissions standards.
    44.    Rivers will require that its haul-truck drivers cover their loads before exiting the quarry
    site, so as to minimize spillage of rock from the truck bed. All other drivers transporting rock
    from the Rivers quarry will be directed to do so as well. Rivers will also install a sign at the base
    of the quarry access road to remind all truck drivers to cover their loads before exiting the site.
    45.    Several parties expressed concern about rock product spilling from the haul trucks and
    dislodging from the haul-truck tires when the trucks exit the quarry and travel onto Route 100B.
    In response, Rivers committed to installing a cobblestone strip at the base of the access road to
    help dislodge this rock from truck tires, inspecting the intersection of the quarry access road and
    Route 100B on a daily basis, and sweeping or cleaning it as needed.
    46.    The federal Mine Safety Health Administration (“MSHA”) administers regulations
    governing mines and quarries such as the Rivers quarry. In particular, the MSHA regulations
    were established to protect mine and quarry workers from particulate emissions in such a manner
    -12-
    that it is not necessary for such workers to use breathing apparatuses. There was no convincing
    evidence that the Rivers quarry will be operated in violation of the MSHA regulations.
    47.    The Vermont Air Pollution Control Regulations (“Air Regulations”) authorize ANR to
    require a project applicant to conduct air dispersion modeling for a project site or other affected
    areas. Air Regulations § 5-406. ANR did not request Rivers to conduct any such air modeling.
    Nonetheless, Rivers conducted air dispersion modeling for the quarry-related impacts at the
    project site and in Moretown Village.
    48.    The federal Environmental Protection Agency (“EPA”) has established air standards
    known as the National Ambient Air Quality Standards (“NAAQS”) for coarse and fine
    particulate matter (measured as PM10 and PM2.5, respectively, which references the diameter of
    the particulate matter in micrometers). While Vermont has not fully implemented the federal
    NAAQS standards, they have historically been used in some Act 250 proceedings where
    conformance with Act 250 criterion 1(A) has been contested.
    49.    The principal source of air emissions from the quarry will be the portable crusher. The
    remaining quarry activities will also cause air emissions, especially the traversing of the quarry
    floor and unpaved access road by quarry equipment and haul trucks.
    50.    No background data concerning historical air emissions was available for the project site
    or Moretown Village. Rivers’ air expert therefore relied upon recommendations provided by
    ANR for other Vermont communities where air emission data was available. Rivers’ air expert
    then added the background data available from other Vermont communities to the air emissions
    the quarry operation was estimated to produce. While this exercise did not provide a perfect
    prediction of the consequent air quality readings at the site and in the Village, if the quarry were
    to operate, it served as reliable evidence concerning resulting air quality. Based upon this
    modeling, the most credible evidence showed that the quarry operation is unlikely to exceed air
    quality standards established in the Vermont Air Regulations and NAAQS.
    51.    Rivers air modeling predicts, as perhaps may be expected, that the quarry’s highest
    concentration of air emissions will occur on site, at the quarry walls, near where the rock crusher
    and drill would operate.
    52.    Air modeling that Rivers conducted in Moretown Village focused upon diesel emissions
    from haul trucks. This modeling was based upon an assumption that most haul trucks would
    pass through Moretown Village, so as to model the highest possible impact from quarry
    -13-
    operations. Rivers’ air modeling also took into consideration the river valley setting of the
    Village, and assumed that peak haul-truck traffic traveling through the Village would coincide
    with the most adverse meteorological conditions in regard to air quality.
    53.     The Rivers’ modeling provided a credible prediction of the probable impact from the
    proposed quarry operation on Village air quality. The Rivers’ modeling estimated that the
    quarry operation would have a minimal or no measurable increase on the air quality in the
    Village.
    Legal Conclusions as to Air Pollution Impacts (Act 250 criterion 1 (air) and Zoning
    Regulations § 4.10(B)(4)).
    Act 250 criterion 1 concerning air pollution, codified in 10 V.S.A. § 6086(a)(1), requires
    that a permit may only issue when a finding is made that the proposed project “will not result in
    undue . . . air pollution.” 10 V.S.A. § 6086(a)(1). While the criterion provides no specific air
    quality levels, it directs that the district commission, and by analogy, this Court on appeal, 6
    consider several factors, the most applicable to air quality being “the applicable health and
    environmental conservation department regulations.” Id. In considering the applicable federal
    and state air quality standards, the most credible evidence presented causes us to conclude that
    the proposed quarry will not result in the “undue air pollution” against which Act 250 criterion 1
    seeks to protect.
    The historical interpretations of Act 250 criterion 1 concerning air pollution do not
    establish a sole reliance upon governmental air quality standards, but rather vest the adjudicating
    tribunal with the responsibility of determining whether all applicable factors support a finding of
    undue air pollution. For example, in its decision in McLean Enterprises Corp., the former
    Vermont Environmental Board noted that:
    Nothing in Act 250 specifically defines “undue air pollution.” There are a
    wide range of potential substances and nuisances that may be considered air
    pollution. Whether a pollutant is “undue” depends on factors such as the nature
    and amount of the pollution, the character of the surrounding area, whether the
    pollutant complies with certain standards or recommended levels, and whether
    effective measures will be taken to reduce the pollution. “Undue” has been
    defined . . . to mean “that which is more than necessary—exceeding what is
    appropriate or normal.”
    6
    We are directed to apply “the substantive standards that were applicable before the tribunal appealed from,” which
    in this case would be the District #5 Environmental Commission. 10 V.S.A. § 8504(h).
    -14-
    Re: McLean Enters. Corp. No. 2S-1147-1-EB, Findings of Fact, Conclusions of Law, and Order
    at 41 (Vt. Envtl. Bd. Nov. 24, 2004) (citation omitted) (quoting Brattleboro Chalet Motor Lodge,
    Inc., #4C0581-EB, Findings of Fact, Conclusions of Law, and Order at 6 (Vt. Envtl. Bd. Oct. 17,
    1984)).
    While both the Town and the Neighbors offered much in the way of criticism of Rivers’
    air modeling and other presentations under criterion 1 (air), they offered little evidence
    specifically contradicting Rivers’ actual estimates.        As the former Environmental Board
    reinforced in McLean and Brattleboro Chalet, whether a project will generate “undue” air
    pollution establishes a threshold beyond mere annoyance. Here, while Rivers’ proposed quarry
    will bring about concerns justified under other criteria addressed in this Decision, the most
    credible evidence presented fails to support a finding that the air pollution the Rivers quarry will
    generate constitutes “undue” air pollution.
    Before leaving the question of air pollution, we note that the noise a proposed project
    may generate can be of such an adverse level as to constitute air pollution. See Re: Bull’s-Eye
    Sporting Center, No. 5W0743-EB, Findings of Fact, Conclusions of Law, and Order at 14 (Vt.
    Envtl. Bd., Feb. 27, 1997) (“The test for undue air pollution caused by noise is whether the noise
    has ‘impacts rising above annoyance and aggravation to cause adverse health effects such as
    hearing damage.’” (quoting Re: Talon Hill Gun Club’ Inc. and John Swininem, No. 9AO192-2-
    EB, Findings of Fact, Conclusions of Law, and Order at 8 (Vt. Envtl. Bd., June 7, 1995))). There
    was no evidence presented in these proceedings that Rivers’ proposed quarry will cause noise to
    be emanated from the site at such a high level as to cause such health effects and hearing
    damage. We therefore conclude that the proposed Rivers quarry satisfies Act 250 criterion 1
    concerning air pollution.
    We address noise effects further in our analysis under Act 250 criterion 8, together with a
    review of the effects of quarry noise under the applicable Zoning Regulations.
    The Zoning Regulations also provide for the restriction of projects that contribute smoke,
    dust, dirt, or noxious gases that endanger or adversely affect the health, comfort, safety, or
    welfare of the public. Zoning Regulations § 4.10(B)(4). No credible evidence provided a
    foundation for a determination that the Rivers quarry would emit air pollutants at such a harmful
    level. We therefore conclude that the quarry’s air emissions conform to this regulation.
    -15-
    B.      Water Pollution and Waste Disposal (Act 250 criteria 1 (water), 1(B) and 1(D); Zoning
    Regulations §§ 3.5(C)(3), 4.10(B)(5), and 5.2(D)(5)).
    54.     The Rivers quarry site includes intermittent streams, although none will be impacted by
    the quarry operations. Initially, no wetlands were identified on the Rivers property. Further
    examination confirmed that there were no wetlands that federal or state regulations required be
    protected (i.e., Class I or Class II wetlands), although there were three less significant wetlands
    identified on the Rivers site, all classified as Class III wetlands.
    55.     Due to the rising topography of the site, the Rivers quarry will be higher in elevation than
    any drinking water well in the vicinity. The nearest drinking water well is approximately 1,000
    feet away and serves a primary residence. It was undisputed that the lowest elevation of the
    quarry floor will be 105 feet above the top of this nearest residential well.
    56.     Water currently flows through the project site in the form of rain water, intermittent
    stream flows, and ground water. The topography of the site directs some of this water through
    the project area and towards Route 100B. Some of this water leaches into the ground; some
    flows over the ground, collects in a ditch along the westerly edge of Route 100B, and passes
    through three culverts that transmit the collected waters under Route 100B to outflows on the
    easterly side of the highway. The evidence presented tended to show that, except in extreme
    storm events, this flow of water does not currently cause damage to adjoining properties,
    including the primary residential property of Mr. and Mrs. Hendrickson.
    57.     During the proposed quarry operations, rain water and some ground water will flow into
    the quarry area. Rivers intends to construct a detention pond into which stormwater will be
    directed from the quarry area. Rivers has significantly increased the size of this detention pond
    since it first submitted its applications in order to accommodate the estimated flows of surface
    and ground water through the project site and to provide sufficient water storage for Rivers’ dust
    suppression plans. The pond will be clay lined to minimize infiltration of the detained water into
    the ground; the pond is designed to treat the collected water so that silt and other materials that
    flow with the water will settle into the base of the pond.
    58.     Treated stormwater will then travel from the detention pond to the nearest preexisting
    Class III wetland. Only after the collected water passes through this wetland will it then possibly
    travel across the remaining Rivers parcel and into the culverts under Route 100B. The most
    -16-
    credible evidence shows that the quarry will not cause a measureable increase of stormwater, or
    the contaminants it may carry, to areas beyond the boundaries of the Rivers parcel.
    59.       The proposed quarry is not located within a floodway or floodway fringe of any river or
    stream.
    60.       The Neighbors and the Town expressed concern that Rivers’ use of water misting and
    spray will cause a flow of water that will transmit silt and pollutants from the quarry area and
    access road into groundwater and stormwater, including that which is directed to the detention
    pond. The manner in which Rivers pledged to apply the mist and spray for dust suppression does
    not support these claims. It is most likely that the applied water will evaporate in its application
    to the dust and surrounding surfaces. Were we to approve this project, we would condition
    approval upon an application of water in a manner that causes no runoff or transmission of silt or
    pollutants.
    61.       ANR fulfills its obligation to protect and guard against pollution of ground and surface
    waters by administering a variety of regulations governing the discharge into waters of the State.
    In this regard, ANR administers several permit proceedings that may be applicable to quarry
    discharges, including programs that permit direct discharges, indirect discharges, and the control
    of underground injections. Initially, Rivers and the parties debated the applicability of these
    permit proceedings to the Rivers quarry.
    62.       Rivers sought determinations of whether its proposed quarry required a direct or indirect
    discharge permit or an underground injection control permit. The ANR determinations on these
    requests, or subsequent permit determinations were appealed to this Court. See In re Rivers Dev.
    ANR Underground Injection Control Jurisdiction Opinion Appeal, No. 183-8-07 Vtec and In re
    Rivers Dev. Indirect Discharge Jurisdiction Opinion Appeal, No. 248-11-07 Vtec. Both of these
    appeals were ultimately dismissed, pursuant to a Decision and Judgment Order in those Dockets,
    both filed on November 24, 2008, thereby rendering as final the ANR determinations regarding
    such discharge permits. Id.
    63.       Rivers continued to preserve its appeal of ANR’s denial of its amended direct discharge
    permit application, but subsequently sought dismissal of its own application; the Court granted
    Rivers’ dismissal request. See In re Rivers Dev., LLC Direct Discharge Permit Application (3-
    1524), No. 157-7-08 Vtec, Entry Order (Vt. Envtl. Ct. April 9, 2009).
    -17-
    64.     Rivers sought dismissal of its own ANR discharge permit appeals, and consented to the
    dismissal of the Neighbors’ appeal of the ANR determination, because Rivers, in consultation
    with ANR officials, determined that the most appropriate vehicle for the regulation of quarry
    discharges was to seek and secure ANR’s approval for coverage of its planned quarry activities
    under the National Pollution Discharge Elimination System (“NPDES”) 7 Multi-Sector General
    Permit (“MSGP”). The MSGP is a NPDES permit that covers new and existing discharges from
    quarries, mining, and industrial facilities into the waters of the State.
    65.     The current MSGP (#3-9003) became effective on August 18, 2006, and continues
    through August 18, 2011, when it will be subject to renewal. Quarrying and mining activities are
    governed by MSGP Subsection J, which includes crushed and processed stone projects.
    66.     To receive authorization for coverage under the MSGP, Rivers submitted a Stormwater
    Pollution Prevention Plan (“SWPPP”), into which are incorporated an Erosion Prevention and
    Sedimentation Control plan (“EPSC”) and a Best Management Practices (“BMPs”) protocol for
    its quarry operations.
    67.     Under the MSGP, Rivers is responsible for maintaining all BMPs identified in its
    SWPPP, including (but not limited to) the BMPs associated with the use and maintenance of its
    detention pond. These responsibilities continue until the quarry operations are terminated, the
    site is reclaimed, and the MSGP coverage is no longer required.
    68.     On January 8, 2009, ANR approved Rivers for coverage under MSGP #3-9003, including
    a specific Authorization to Discharge—Permit No. 4103-9003—a copy of which was admitted
    into evidence as Exhibit No. 101. No appeal was taken from ANR’s MSGP authorization
    determination.
    69.     No hazardous materials or waste will be stored or disposed of on site during the operation
    of the quarry. ANR determined that Rivers is not required to obtain a hazardous waste disposal
    permit for its quarry project.
    70.     Neighbors expressed fears that the blasts proposed for the quarry site will not consume all
    components of the blasting charges. Such materials constitute hazardous waste; the Neighbors
    expressed concern that such materials, if not fully consumed, would be transported by rain and
    ground water to the groundwater aquifer and to off-site areas. However, the most credible
    7
    ANR administers the federal NPDES program through a delegation of authority by the federal EPA, pursuant to
    provisions of the federal Clean Water Act, and ANR does so in conjunction with its administration of the Vermont
    Water Quality Act.
    -18-
    testimony and other evidence was that all such blasting materials will be consumed when
    incorporated into Rivers’ planned quarry blasts and therefore would not enter the stormwater or
    groundwater, or otherwise contaminate waters on or off site.
    71.    One of the blasting agents that gave Neighbors their greatest concern was perchlorate,
    which is a recognized carcinogen. Rivers confirmed that its blasts will not use compounds
    containing perchlorate.
    72.    When the area of the access road and sight distance improvements along Route 100B are
    included into the calculations, Rivers proposes to clear cut, strip, or otherwise disturb a total
    of 23.39 acres of its property. At no time, however, will this entire area be left disturbed,
    unprotected from erosion, or not reclaimed.
    73.    The first phase of construction will include improvements to the access road, the sight
    distance area along Route 100B, and the area identified as “Phase 1” on Rivers’ final amended
    site map (Ex. R-4(E), p. 1). This Phase 1 area includes establishment of the detention pond and
    the initial phase of the quarry floor area. The lowest point of the quarry floor will have an
    elevation of 820 feet above sea level.
    74.    Once construction, blasting, excavation, and extraction work has been completed in the
    initial phase, Rivers will begin work in a second phase. No more than two phases of the quarry
    will remain open or disturbed at a given time; once work is completed in one phase, and while
    work is being conducted in a second phase, Rivers will commence reclamation work in the
    completed phase. These procedures will minimize the opportunity for stormwater to escape the
    planned detention swales and pond, and will minimize the aggregate flow of stormwater over the
    exposed quarry area and from the project site.
    Legal Conclusions as to Water Pollution Impacts (Act 250 criteria 1 (water) and 1(B);
    Zoning Regulations §§ 3.5(C)(3), 4.10(B)(5), and 5.2(D)(5)).
    Similar to our analysis under Act 250 criterion 1 concerning undue air pollution, our
    analysis here centers on the question of whether the quarry will produce undue water pollution.
    10 V.S.A. § 6086(a)(1). Criterion 1(B) presents a similar legal issue in that we are asked to
    determine whether the proposed quarry “will meet [all] applicable health and environmental
    conservation department regulations regarding the disposal of wastes, and will not involve the
    injection of waste materials or any harmful or toxic substances into groundwater or wells.” 10
    V.S.A. § 6086(a)(1)(B).
    -19-
    The parties engaged in a vigorous debate over the multitude of ANR permits that could
    be required for this project. This debate sometimes included ANR, the very entity charged with
    the administration of such permits. At one point, these consolidated proceedings included five
    different dockets, but were reduced to two dockets by stipulations of the parties and orders of
    this Court, as detailed in Findings No. 58–62. All the resolved dockets concerned questions of
    whether, and under what conditions, a certain type of ANR permit was required for this quarry.
    The remedy to these combined questions offered by Rivers and ANR provides the most
    credible response: that coverage under the current NPDES Multi-Sector General Permit provides
    the most comprehensive administration for the protection of surface and ground water, as well as
    the management of waste and any other contaminants that may flow with stormwater and
    groundwater. None of the contested ANR permits provided this comprehensive review; two of
    the ANR determinations from which appeals were taken concerned jurisdictional determinations
    that the Rivers quarry did not need to acquire such permits.
    MSGP #3-9003, including Authorization to Discharge Permit No. 4103-9003, provides a
    specific protocol for Rivers’ operation of its quarry and treatment of stormwater, including a
    requirement to abide by the approved BMPs protocol. Pursuant to its application and SWPPP,
    Rivers asserted that no “processed generated wastewater,” as that term is defined in 
    40 C.F.R. § 436.21
    (e), which would require additional ANR discharge permits, will be discharged from the
    project site. Rivers’ SWPPP and BMPs protocols impose a continuing obligation upon Rivers to
    identify and disclose to ANR any such future discharges.
    The Neighbors and the Town expressed concerns regarding the flow of wastes and
    hazardous materials into groundwater and from the project site.         They offered persuasive
    arguments for why all stormwater, including general rainfall upon the project site, should be
    regarded as wastewater. But we find no statutory rationale for such a broad definition of the
    term “wastewater.” In fact, we fear that such a broad definition would include all rain water that
    falls upon any developed property. Without a clear statutory directive for such a broad statutory
    definition of wastewater, we decline to embrace it.
    We therefore conclude that the admitted evidence supports our conclusion that the Rivers
    quarry, were it to be approved and operated in accordance with the SWPPP and BMPs
    established under the approved MSGP coverage, would not contribute undue water pollution and
    will conform with all applicable health and Department of Environmental Conservation
    -20-
    regulations. We further conclude that the project as proposed will not involve the injection of
    waste materials or any harmful or toxic substances into groundwater or wells. We therefore
    conclude that the proposed quarry would be in conformance with Act 250 criteria 1 and 1(B).
    The Zoning Regulations provide similar protections in the following three provisions:
    •   Section 3.5(C)(3) prohibits projects that will have an “undue adverse effect” on surface
    waters;
    •   Section 4.10(B)(5) prohibits projects from causing any discharge of harmful wastes into
    any public waters, wetland, or aquifer; and
    •   Section 5.2(D)(5) requires a project developer to manage stormwater in such a manner
    that there will be no adverse impacts to neighboring properties, town roads, or water
    quality.
    As noted in our analysis under Act 250 criteria 1 and 1(B), the project conforms to all
    applicable discharge and waste regulations. While the Neighbors’ and Town’s arguments were
    persuasive and exhaustive, the most credible evidence supports our conclusion that if the Rivers
    quarry were operated as proposed, and in conformance with the approved MSGP coverage, the
    quarry will not cause undue adverse effects upon surface waters, will not discharge harmful
    wastes, and will not cause water discharges that will impose an adverse impact upon neighboring
    properties, town roads, or water quality.
    Legal Conclusions as to Flood Waters (Act 250 criterion 1(D)).
    Act 250 criterion 1(D) requires an initial determination of whether the proposed project is
    located within a floodway or floodway fringe and, if so, whether the project will be operated in
    such a manner as to restrict, divert, or significantly increase the flow of flood waters. Neither the
    Rivers project in general, nor its quarry site in particular, are located within any floodways or
    fringe areas of any river or stream.
    Stormwater currently travels from the undeveloped Rivers parcel; some stormwater
    travels under Route 100B and eventually makes its way to the Mad River. Since we have
    concluded that the proposed quarry will not measurably increase the flow of stormwater off of
    the Rivers parcel, and have concluded that the quarry construction and operation will not
    introduce contaminants or hazardous materials into the stormwater that travels from the Rivers
    parcel, we conclude that the project as proposed conforms to Act 250 criterion 1(D).
    -21-
    C.      Impact upon Streams, Shorelands, and Wetlands (Act 250 criteria 1(E) and 1(F); 8 Zoning
    Regulations §§ 3.5(C)(3), 4.10(D)(5), and 4.11(B)).
    75.     There were no streams identified within the quarry area. The Mad River is buffered from
    the quarry project by the remaining lands of Rivers, Route 100B, and lands of Rivers’ neighbors
    adjacent to Route 100B. The Mad River lies to the east of these neighbors’ lands. Quarry land
    disturbances will be no closer than 1,000 feet to the Mad River.
    76.     The three Class III wetlands identified on the Rivers parcel have been assigned the
    following identification tags: 2001-1, 2007-2, and 2007-3. They were discovered in 2007, after
    Rivers filed its applications, and after it caused its wetlands expert to reexamine the parcel.
    77.     These three wetlands have been classified as Class III wetlands pursuant to state and
    federal regulations, due either to their small size or relative insignificance, or both. 9 They are
    not afforded the protections under federal and state laws that are afforded to Class I and Class II
    wetlands.
    78.     The Rivers quarry will not disturb wetlands 2007-1 and 2007-2 and will respect a fifty-
    foot buffer surrounding each of these wetlands.
    79.     Rivers’ site plan initially envisioned that the quarry and its service road would encroach
    into wetlands 2007-3. Part of Rivers’ revisions to its site plan reduced the encroachment into the
    wetlands to only the splash pad that would be installed for the run-off area from the detention
    pond; this encroachment will be limited to 140 square feet of the wetland and a consequent area
    of the wetland buffer, as delineated on Rivers’ revised site plan (Ex. R-4(E)). In all other
    respects, Class III wetlands 2007-3 and its fifty-foot buffer will be undisturbed.
    80.     Only two streams were identified on the Rivers parcel. An intermittent stream, identified
    as 2007-TB-1, flows from wetlands 2007-1. Quarry activities will respect an undisturbed, fifty-
    foot buffer along this stream.          An unnamed tributary of the Mad River is located on the
    southwest portion of the Rivers parcel. No quarry activities will come within 450 feet of this
    unnamed tributary. Analysis conducted on behalf of ANR confirmed that no other steams were
    identified on the Rivers parcel.
    8
    Act 250 Criteria 1(G) also addresses impacts upon “significant wetlands.” 10 V.S.A. § 6086(a)(1)(G). We do not
    review conformance with criteria 1(G) because no party appealed that issue to this Court. We therefore only address
    impacts upon wetlands pursuant to the applicable Zoning Regulations.
    9
    Class III wetlands are defined as all wetlands that are not significant enough to qualify as Class I or Class II
    wetlands. Vermont Wetland Rules §§ 4.1–4.4, 6 Code of Vermont Rules 12 004 056-10 (2002).
    -22-
    Legal Conclusions as to Impacts on Streams, Shorelands, and Wetlands (Act 250 criteria
    1(E) and 1(F); Zoning Regulations §§ 3.5(C)(3), 4.10(B)(5), 4.11, and 5.2(D)(5)).
    Act 250 criterion 1(E) directs that a proposed project must be shown to “whenever
    feasible, maintain the natural condition of the stream[s on or adjacent to the project], and . . . not
    endanger the health, safety, or welfare of the public or of adjoining land owners.” 10 V.S.A.
    § 6086(a)(1)(E). The quarry will not encroach upon or interfere with the streams on the Rivers
    parcel. Intermittent stream 2007-TB-1 and its fifty-foot buffer will be left undisturbed; the Mad
    River tributary in the southwest portion of the Rivers parcel will enjoy a 450-foot buffer from the
    quarry activities. The quarry as proposed will conform to criterion 1(E).
    Criterion 1(F) provides similar protection to shorelands. See 10 V.S.A. § 6086(a)(1)(F)
    (providing protection for shorelands “in their natural condition” when encroached upon by
    development). Our review of criterion 1(F) is equally succinct, since the Rivers parcel contains
    no shorelands and the quarry project will not impact any shorelands. Conformance with criterion
    1(F) is also proved.
    The Zoning Regulations contain several independent sections that seek to protect streams,
    neighboring properties, and wetlands from a project’s potential adverse impacts in regard to
    stormwater or other runoff. Subsection 3.5(C)(3) directs the DRB, and therefore this Court on
    appeal, to determine whether a proposed extraction of earth resources 10 will “cause a hazard to
    public health or safety, or otherwise have an undue adverse effect on: . . . surface and ground
    water[s] . . . .” Regulations § 3.5(C)(3). Subsection 5.2, governing the conditional use review
    standards for all land use activities, and made applicable to the Rivers quarry by reference in
    § 3.5, requires that stormwater from a project site be managed “to ensure that such runoff will
    not result in adverse impacts to neighboring properties, town roads, or water quality[, and that a]
    stormwater management and/or erosion control plan may be required and incorporated as a
    condition to approval.” Regulations § 5.2(D)(5).
    Given our previous Findings, we conclude that the Rivers proposed quarry conforms to
    these municipal regulatory provisions.               The coverage under MSGP #3-9003, including the
    SWPPP and BMPs Rivers has committed to follow in its construction and operation of the
    10
    Zoning Regulations § 3.5 specifically regulates the extraction of earth resources; it notes that the “removal of soil,
    sand, rock, stone or gravel . . . may be permitted in designated zoning districts subject to conditional use review in
    accordance with Section 5.2 and findings that the proposed” extraction activity meets the specific standards of § 3.5
    and any other applicable standards contained in the Zoning Regulations. Regulations § 3.5(a).
    -23-
    quarry, provide adequate assurances that surface and groundwater will not be adversely affected,
    and that neighboring properties, town roads, and water quality will not suffer because of the
    runoff from the Rivers quarry. The SWPPP and BMPs that Rivers has committed to follow in
    connection with its coverage under this NPDES general permit provide adequate stormwater
    management and erosion control provisions.
    Regulations § 4.10(B)(5) prohibits “discharge of sewage, septage, or other harmful
    wastes into any public water, wetland, [or] aquifer” from a project. Regulations § 4.10(B)(5).
    The Neighbors and the Town expressed concerns regarding the quarry’s introduction of
    hazardous materials into the surface and ground waters. As we noted in our prior analysis
    concerning water pollution impacts (supra pp. 19–20), the opposing parties expressed legitimate
    concerns regarding the quarry’s possible introduction of hazardous materials into the waters that
    flow on, through, and under the parcel. However, the most credible evidence supports our
    conclusion that the quarry as proposed will not commit these offenses.
    Subsection 4.11 provides for protection of streams, streambanks, and wetlands.                                It
    provides for a buffer from streams and their banks (twenty-five feet) that is narrower than that
    called for in state regulatory review (fifty feet or more) and less than that provided in Rivers’ site
    plans. Regulations § 4.11(B). This regulatory provision prohibits encroachment into a stream
    buffer strip, with limited exceptions not applicable to the Rivers project. See Regulations
    §§ 4.11(B)(1)–(5). No aspect of the Rivers quarry project will encroach into a stream or its
    buffer. Subsection 4.11(E) provides for protection of Class I and Class II wetlands and their
    fifty-foot buffers. Since no Class I or II wetlands will be impacted by the Rivers quarry, the
    proposed project satisfies the requirements of subsection (E). 11
    We therefore conclude that the construction and operation of the proposed quarry
    conforms to all zoning regulations applicable to possible impacts upon streams, shorelands, and
    wetlands, and the possible impacts that may flow from those waters onto adjoining neighbors’
    properties or town roads and general water quality.
    11
    The second sentence of this subsection uses the general term “wetlands.” We understand this reference to be to
    the specific wetlands identified in the first sentence of § 4.11(E) (i.e., Class I and II wetlands), and not as a general
    reference to all wetlands.
    -24-
    D.     Impacts Upon and Adequacy of Water Supplies (Act 250 criteria 2 and 3; Zoning
    Regulations §§ 3.5(C)(3) and 4.10(B)(5)).
    81.    The principal and perhaps sole material use of water in the quarry operations will be the
    application of water by mist and spray on the quarry floor, stockpiles, access road, and via the
    apparatuses attached to the rock drilling, crushing, and sorting machines. The water mist and
    spray will be regulated to only use so much water as is necessary to dampen and suppress the
    dust that will arise in the quarry operations. This water application will not be so excessive as to
    cause the water flow that the opposing parties fear may transport stormwater or contaminants.
    82.    The source of the water used in this misting and spraying processes will be the planned
    detention pond, to be located and initially constructed in the first phase of the project
    83.    This detention pond will be constructed in two stages as the quarry operation progresses.
    The expected annual recharge of water detained in the first stage pond is best estimated to be
    over 500,000 gallons; when the second stage construction of the pond is completed, the annual
    recharge is estimated to be over 1,000,000 gallons. These recharge estimates were credibly
    calculated using the driest historical rainfall data for the region and calculated based upon only a
    small area (five to ten acres) from which the rainfall will be contributed.
    84.    The operation using the largest amount of water at the quarry will be rock crushing. The
    crusher mists the rock during processing at the rate of 1.8 gallons of water per minute, which will
    equate to about 1,080 gallons of water per operational day. The credible evidence was that the
    remaining uses of detention pond water (for suppressing dust on the quarry floor, the access
    road, and stockpiles) will be at a rate of about 200 gallons of water per day. Based upon these
    calculations, it is estimated that the quarry will need approximately 123,000 gallons of water per
    year for its dust suppression and other operations. This estimate is a fraction of the water that the
    detention pond will make available, even in a year that mirrors historically low rainfall rates.
    85.    The parties concurred that there are eleven residences within a 2,000-foot radius of the
    quarry site, all served with on-site wells for water supply. Most wells supplying water to
    residences are over 1,000 linear feet away from the quarry site.
    86.    The quarry is also separated from these residential water supply wells by elevation; the
    quarry floor is no less than 105 feet in elevation above the highest residential wellhead. Most
    wells are a far greater distance away from the quarry site.
    -25-
    87.    Based upon the expert testimony offered by all offering parties, the most credible
    evidence is that the groundwater aquifer located beneath the quarry site begins more than 200
    feet underneath the quarry floor, thereby negating the assertion that quarry activities will directly
    impact an underground aquifer from which the residential wells will immediately draw water.
    88.    The parties disputed the extent, direction, and duration of fractures in the rock at and
    below the quarry site. Underground rock fractures allow surface and ground water to travel
    quickly, without the benefit of filtration through soil and sand. While rock fractures are evident
    at the quarry site, the assertion by Neighbors’ expert regarding the extensive nature of significant
    rock fracture at the quarry site and beyond was not credible.
    89.    Rivers also proposed to take quality and quantity tests of all wells within 2,000 feet of the
    quarry site, where allowed by the well owners, prior to the commencement of quarry activities.
    These tests would provide baseline, pre-quarry data for the tested wells. Rivers would also
    conduct interim testing of these same wells during operation of the quarry. Were we to permit
    the quarry to be constructed and operated, we would adopt Rivers’ recommendation that it be
    required to remediate or replace water supply wells that this data evidenced were impacted by
    the quarry operation.
    Legal Conclusions as to Impacts Upon and Adequacy of Water Supplies (Act 250 criteria
    2 and 3; Zoning Regulations §§ 3.5(C)(3) and 4.10(B)(5)).
    Act 250 criteria 2 and 3 are commonly reviewed in tandem. The former asks whether
    there is sufficient water supply available “for the reasonably foreseeable needs of the” project;
    the latter prohibits the project from having “an unreasonable burden on an existing water
    supply.” 10 V.S.A. §§ 6086(a)(2)–(3). For the reasons stated below, and the Findings stated
    above, we conclude that the Rivers quarry conforms to both criteria.
    While the opposing parties expressed several legitimate concerns, when expressed in
    general terms, the most credible evidence is that there will be more than enough water available
    for the proposed quarry activities, and that those activities are unlikely to cause a burden or
    adversely impact neighboring water supply wells. Even with this factual foundation, Rivers
    proposes a reasonable and reliable mechanism for identifying possible impacts to neighboring
    wells, and it commits to being responsible for remediation of any wells that are burdened or
    adversely impacted by quarry operations. While we would accept this testing and remediation
    condition if we were to permit this quarry, we were persuaded that remediation would not likely
    -26-
    be needed at the Rivers quarry due to the manner in which the quarry would be operated and the
    distance (both over land and in elevation) between the quarry and the nearest neighboring wells.
    We found persuasive the testimony of Rivers’ expert that, during his many years of experience
    concerning quarries and conformance with Act 250 criterion 3, he has not identified a quarry
    with isolation distances and operational designs similar to the Rivers quarry that has impacted a
    neighboring well.
    Zoning Regulations §§ 3.5(C)(3) and 4.10(B)(5), referenced in the above discussion on
    streams, shorelands, and wetlands, provide protections similar to Act 250 criteria 2 and 3. For
    the same reasons as noted in our discussion of Regulations §§ 3.5(C)(3) and 4.10(B)(5), we
    conclude that the project as proposed will conform to these municipal regulatory requirements in
    regards to possible impacts upon neighboring wells.
    E.      Soil Erosion (Act 250 criterion 4; Zoning Regulations §§ 3.5(C)(3) and 4.10(B)(5)).
    90.     The topography of the Rivers parcel in general and the quarry site in particular includes
    many areas with slopes ranging from 15% to 25%.               Some areas, especially along rock
    outcroppings, exceed 25% slope. Excavation and clearing of the site could therefore cause
    significant erosion if proper erosion control measures were not installed.
    91.     Rivers will employ many erosion control measures; their erosion control plan was
    reviewed and approved by ANR in connection with Rivers’ application for coverage under the
    MSGP.
    92.     On areas of steep slopes, Rivers will employ rolled erosion control mats and crushed
    stone as well as other measures recommended by ANR in its administration of the Vermont
    Standards & Specifications for Erosion Prevention & Sediment Control.
    93.     Quarry areas will be disturbed and cleared in phases. No more than two complete phases
    will contain areas of exposed earth that would be susceptible to erosion. All stormwater entering
    the quarry area will be directed to the constructed pond for detention and treatment. Ditches and
    water bars along the access road will minimize its erosion.
    94.     In addition to these physical erosion control measures, Rivers pledges to cause weekly
    and special inspections to be conducted by an on-site erosion control coordinator, pursuant to the
    Stormwater Construction General Permit, to assure that the installed erosion controls are
    performing as designed, including during significant rains.
    -27-
    Legal Conclusions as to Soil Erosion (Act 250 criterion 4; Zoning Regulations
    §§ 3.5(C)(3) and 5.2(D)(5)).
    Act 250 criterion 4 obligates us to determine that the proposed quarry “[w]ill not cause
    unreasonable soil erosion or reduction in the capacity of the land to hold water so that a
    dangerous or unhealthy condition may result.” 10 V.S.A. § 6086(a)(4). The most credible
    evidence is that no such soil erosion or unsafe conditions will result from the construction and
    operation of the Rivers quarry.
    This site provides many challenges to an erosion control planner due to its slopes and the
    planned soil disturbances. Such challenges often appear in areas where sand, gravel, and rock
    have value sufficient to justify the expense of extraction. Rivers and its experts and consultants
    have worked cooperatively with ANR officials to plan for these erosion challenges and have
    presented a plan that will assure against the adverse impacts from which criterion 4 seeks to
    protect. The erosion control measures Rivers proposes to put in place allow us to render a
    positive finding under criterion 4.
    Zoning Regulations §§ 3.5(C)(3) and 5.2(D)(5) provide similar protections from the
    dangers of soil erosion. The Rivers quarry and its erosion control plans provide sufficient
    conformance with those Regulations.
    III. Traffic.
    95.    Stone and processed rock for development within the Mad River Valley currently is
    extracted from quarries far outside of Moretown, including quarries located in Berlin, South
    Barre, Williamstown, Williston, Granville, Hinesburg, Bolton, Northfield, and Morrisville. The
    rock product from these quarries travels to the sites of its end use within the Mad River Valley
    via Vermont Route 100 (both from the north and south), Vermont Route 17, Interstate 89,
    Moretown Town highways (including Moretown Mountain Road, taking haul trucks through its
    dangerous intersection with Main Street), and Route 100B.
    96.    A rock quarry identified as operating in the Town is at the Moretown Landfill. The rock
    extracted from the Landfill quarry is inferior to the rock that would be available from the Rivers
    quarry; this point was confirmed by the Town Highway Foreman, who purchases rock, gravel,
    and sand for the Town on a regular basis.
    97.    In addition to quality of stone, the Rivers quarry would have the commercial benefit of
    being closer to its customers in the Mad River Valley and therefore have less highway travel
    -28-
    time and expense. Transportation costs can represent a significant portion of the total cost of
    rock products.
    98.    Many quarries are located in isolated areas, far removed from other land uses with which
    the quarry may conflict. Such locations often require that trucks hauling rock product must
    travel a significant distance over town roads, some of which may be dirt and not adequate to
    support the frequent use by heavy haul trucks.          The Rivers quarry will originate from an
    established rural major collector highway—Route 100B—and will not need to travel over under-
    improved town roads, except in the rare instances when a customer on such a road purchases
    rock product for their individual development.
    99.    Thus, were the Rivers quarry to operate, its haul trucks would begin their travels
    exclusively from Route 100B, whereas the rock purchased for Mad River Valley projects from
    existing quarries begins its travel from several more distant areas; some which do not ever travel
    on Route 100B to reach its destination.
    100.   Rivers’ haul trucks will mostly travel south on Route 100B from the Rivers quarry; some
    may travel north on Route 100B, depending upon the destination designated by the customer.
    101.   Much of the rock product purchased from the Rivers quarry will be delivered by Rivers
    using its own haul trucks. Some rock product will be delivered using customers’ or independent
    contractors’ haul trucks.
    102.   Rivers proposes that the number of one-way haul truck trips from its quarry would not
    exceed 108 one-way trips per operational day; it estimates that the average will be 72 one-way
    trips per operational day.
    103.   Most of the trucks Rivers expects to use to haul rock from its quarry will be single rear
    axle, heavy duty dump trucks, with estimated load capacities ranging from seven to sixteen cubic
    yards. Rivers’ customers and independent contractors will likely use similar trucks. A few
    larger, tri-axle trucks with greater load capacities (up to twenty cubic yards) may be used, but
    these trucks will represent no more than 10% of the trucks used.
    104.   Rivers estimates that the average truck load will be fourteen cubic yards. That average
    load calculates to just over 5,357 truck loads to haul the 75,000 cubic yards that Rivers commits
    to be its maximum annual extraction rate.
    105.   Rock will be loaded from the quarry floor staging area by a backhoe and into the empty
    bed of each haul truck, which will then travel down the 1,400-foot improved access road to the
    -29-
    intersection of Route 100B. Due to the difference in elevation between the quarry floor and the
    access road intersection with Route 100B, these trucks, once loaded, will travel several hundred
    feet down slope in elevation while on the access road. Testimony throughout the trial presumes
    that loaded trucks while on the access road and when returning to the quarry will often use
    engine or “jake” brakes to decelerate.
    106.       Rivers will widen and improve the access road/Route 100B intersection to comply with
    VTrans’ standards for intersections onto state highways, commonly referred to as the “VTrans
    Standard B71.”
    107.       The access road intersection provides for more than adequate sight distances to the south;
    the existing site distance to the south is in excess of 1,500 feet. The existing sight distances to
    the north are inadequate.       Rivers has pledged to improve the northern sight distances by
    excavation and rock removal, including blasting where necessary. Once completed, the sight
    distance to the north will afford a truck driver stationed at the access road intersection to see
    vehicles approaching from the north from up to 895 feet away.
    108.       A truck driver at the access road intersection, waiting to turn onto Route 100B, will need
    to look both ways. Drivers turning to the south will need to have sufficient interruptions in the
    flow of traffic from the north to turn right into the southbound lane of Route 100B and achieve
    acceleration to the lawful or prevailing speed without interfering with the oncoming southbound
    traffic.
    109.       A driver at the access road waiting to turn north onto Route 100B will need to have
    sufficient time (and sight of on-coming traffic to allow for sufficient time) to cross through the
    southbound lane and achieve sufficient acceleration in the northbound lane.
    110.       VTrans initially determined that the Route 100B/access road improvements would
    provide adequate sight distances of on-coming traffic in both directions. VTrans specifically
    determined that the 895-foot sight distance to the north would be adequate for quarry haul trucks
    turning north or south onto Route 100B.
    111.       The posted speed limit for the area of Route 100B adjoining the quarry site is 50 miles
    per hour; the parties agreed that the prevailing speed of the 85th percentile of vehicles traveling
    along Route 100B is 58 miles per hour.
    112.       The Sanders and other neighboring parties expressed concerns to VTrans officials that the
    proposed quarry sight distance to the north would be inadequate for heavy, loaded haul trucks,
    -30-
    even with the improvements planned by Rivers.           VTrans officials reviewed these parties’
    concerns, again evaluated the planned improvements and estimated sight distances, and
    determined that the improved visibility of traffic coming from the north would be adequate for
    the planned haul truck traffic.
    113.      Even with its rural, scenic setting (and perhaps because of it), Route 100B experiences a
    great deal of daily traffic. In fact, by use of traffic counting stations, VTrans estimates that
    Route 100B, in the area just south of the Village, has an annual average daily traffic count
    (“AADTC”) of 3,500 one-way vehicle trips.
    114.      The vast majority of these trips are passenger vehicles. Of these AADTC trips, VTrans
    reports that only 32 are tractor trailers and 181 are single rear axle trucks. The VTrans counters
    have the capacity to distinguish between passenger vehicles, tractor trailers, and single axle
    trucks.
    115.      The counted single rear axle trucks include all forms of delivery trucks, from USPS,
    UPS, and FedEx delivery trucks, general delivery trucks, and small school busses.
    116.      Of these counted one way truck trips, the best estimate is that about sixty-two (62) of
    those one way truck trips were executed by haul trucks similar to those to be used at the Rivers
    quarry.
    117.      VTrans also establishes weight limits for vehicles traveling on state highways. The
    weight limit for single rear axle trucks traveling on Route 100B is 55,000 pounds; 60,000 pounds
    for tri-axle or combination trucks. These weights may be exceeded by trucks for which VTrans
    has issued an overweight highway permit.
    118.      A cubic yard of processed rock weighs between 2,600 to 3,000 pounds. The annual
    maximum of 75,000 cubic yards Rivers estimated would be extracted from the quarry is
    therefore calculated to weigh between 195,000,000 to 225,000,000 pounds.
    119.      A single rear axle haul truck, unloaded, weighs about 22,000 pounds. Its average load (8
    cubic yards) would increase its total weight to about 44,400 pounds. The maximum volume of
    processed rock that could be hauled while keeping the total truck weight below the 55,000 pound
    limit is just below 12 cubic yards.
    120.      To achieve its maximum extraction rate of 75,000 cubic yards per operational year, at the
    average and maximum volumes stated in the above Finding, the truck traffic generated by the
    Rivers quarry would average between thirty-nine (39) and fifty-four (54) daily round-trip truck
    -31-
    trips. This calculation is based upon an average of 160 days in an operational year, with trucks
    loaded with as much as 12 and as little as 8 cubic yards of processed rock, divided into a
    maximum output of 75,000 cubic yards. The maximum of fifty-four (54) round trips per day is
    used because Rivers has pledged not to exceed this daily maximum.
    121.    Rivers’ traffic expert predicts that the proposed quarry will increase the heavy haul truck
    traffic, both on Route 100B generally, and as the highway passes through the Village in
    particular.
    122.    The percentage of the trucks traveling from the Rivers quarry that will pass through the
    Village is uncertain. Rivers’ traffic expert did not offer an estimate as to the number of truck
    trips from the Rivers quarry that will travel north or south from the quarry, nor did he opine as to
    the number of existing haul truck trips originating from other quarries that will now originate
    from the Rivers quarry.
    123.    The opposing parties expressed concern about the increased truck traffic, generally along
    Route 100B, in the Village area, and in particular where Route 100B intersects with town
    highways, especially the intersection in the Village with Moretown Mountain Road. This town
    highway is narrow and winding in places; most of it is unpaved. As Moretown Mountain Road
    approaches the Village intersection, it is steep and arrives at Route 100B at an awkward angle.
    Busses and some trucks travel through this intersection, which creates potentially dangerous
    traffic intersection scenarios.
    124.    Trucks originating at the Rivers quarry will not generally use Moretown Mountain Road
    and are unlikely to turn onto or out of this road from Route 100B in the Village.
    125.    VTrans maintains records of high accident locations along state highways.           VTrans
    reports no high accident locations along state highways in Moretown or Middlesex, including
    along Route 100, US Route 2, or Route 100B, which includes the portion of Route 100B that
    passes through the Village.
    126.    Rivers’ traffic expert conducted a credible analysis of the level of service (“LOS”) for
    affected intersections of state highways, including the intersections between Routes 100 and
    100B, just south of the Village; Route 100B and US Route 2; and the quarry access road
    intersection with Route 100B. This expert analyzed all three intersections using the procedures
    established in a respected highway capacity manual.           This analysis provided a credible
    foundation for concluding that each intersection enjoyed a high LOS rating (rating A or B, on a
    -32-
    scale from A being best and F being worst), and that the quarry operations will not materially
    change those respective LOS ratings.
    Legal Conclusions as to Traffic (Act 250 criterion 5; Zoning Regulations § 5.2(C)).
    The traffic the Rivers quarry is expected to generate caused many concerns that were
    expressed under a variety of Act 250 criteria and municipal regulatory provisions. While we
    have attempted to present a broad range of Findings above, our analysis here is limited to the
    specific concerns expressed in criterion 5 and Regulations § 5.2(C) concerning the project’s
    impact upon the flow of traffic along area roads. Other concerns arising because of the traffic
    generated by the quarry are addressed in subsequent sections of this Decision.
    Act 250 criterion 5 directs that a project may only be approved if it is found to “not cause
    unreasonable congestion or unsafe conditions with respect to use of the highways, waterways,
    railways, airports and airways, and other means of transportation existing or proposed.” 10
    V.S.A. § 6086(a)(5). Criterion 5 concerns the impact a project may have on area highways and
    the traffic that flows over those highways, including whether a proposed project may exacerbate
    an already hazardous traffic situation. In re Pilgrim Partnership, 
    153 Vt. 594
    , 596–97 (1990).
    When reviewing a project’s impact on area traffic, we are reminded that one purpose of Act 250
    is “to insure that Vermont ‘lands and environment are devoted to uses which are not detrimental
    to the public welfare and interests’” of our State. 
    Id.
     (quoting Pub. Act No. 250, § 1 (1969 Adj.
    Sess.); see also In re Juster Assocs., 
    136 Vt. 577
    , 580 (1978).
    Our response to a project’s traffic impacts must be somewhat muted, however, since no
    project may be denied an Act 250 permit solely due to adverse impacts under criteria 5, 6, or 7.
    10 V.S.A. § 6087(b). Further, while an Act 250 applicant bears the initial burden of production
    under all applicable Act 250 criteria, the ultimate burden of proving that a project does not
    conform to criteria 5 through 8 rests upon the project’s opponents. 10 V.S.A. § 6088(b). See
    also In re Route 103 Quarry, No. 205-10-05 Vtec, slip op. at 8 (Vt. Envtl. Ct. Nov. 22, 2006)
    (Durkin, J.), aff’d, 
    2008 VT 88
    .
    In regards to the proposed quarry’s impact upon area traffic, the greatest source of impact
    is, of course, from the traffic that the quarry will generate: maximums of 108 one-way heavy
    haul truck trips and twenty one-way trips by other vehicles (i.e., cars and small truck driven to
    and from the quarry by employees and business invitees). This volume of additional traffic, in
    and of itself, does not cause or contribute to “unreasonable congestion or unsafe conditions.” 10
    -33-
    V.S.A. § 6086(a)(5). Route 100B is designated as a rural major collector highway; the increase
    in vehicle traffic, currently totaling up to 3,500 trips per day, caused by the quarry operations (a
    maximum of 108 trips per day) will not materially decrease the level of service at measured
    intersections at the quarry access road, Route 100B’s intersection with US Route 2 to the north,
    or its intersection with Route 100 to the south.
    Extensive trial testimony centered on the narrowness of Route 100B as it traversed the
    Village area, the proximity of town and school buildings to the highway, and the poor quality of
    Village sidewalks.     Interestingly, the Town was the main proponent during trial of the
    assessment of its sidewalks as dangerous.            The Court found frightful the testimony of
    pedestrians, particularly older individuals with some debilitating medical conditions, fearing and
    actually falling off of the Village sidewalks and into the highway travel lanes. So too was it
    frightful to hear from bicyclists who compete for limited travel space on the Village highway, as
    well as their fear of being thrown from a bicycle, perhaps as it accelerates downhill in the
    vicinity of the quarry access road, due to small stones having been deposited on the highway
    shoulder by passing quarry haul trucks.
    There is no doubt that the Village Main Street portion of Route 100B is dangerously
    narrow and includes dangerous intersections, including its intersection with Moretown Mountain
    Road. The evidence on this portion of the traffic presentation was close and compelling, but we
    cannot conclude on the facts before us that the contribution of quarry haul trucks to the already
    extensive traffic that flows through the Village Main Street is likely to measurably increase the
    congestion and traffic conditions, such that this proposed quarry will cause unreasonable
    congestion or unsafe conditions on area highways. Our conclusion here is premised upon the
    circumstances of existing and proposed traffic, as well as Rivers’ proposal for reasonable traffic
    mitigation measures at the access road intersection. Were we to approve this project, we would
    require Rivers to enforce the following traffic mitigation measures:
    1.     Install a wide strip of cobblestone at the base of the access road, so as to assist in
    dislodging small stone from the haul truck tires before they exit onto Route 100B;
    2.     Regularly inspect this intersection, and regularly sweep or otherwise remove stone and
    rock along Route 100B and its shoulders in the vicinity of its access road; and
    3.     Require all loaded trucks departing the quarry to cover their loads before exiting the
    Rivers property.
    -34-
    Zoning Regulations §5.2, the provision relating to general conditional use review
    standards, provides in subsection (C)(3) a review standard quite similar to Act 250 criterion 5:
    that a project’s impact upon the “condition, capacity, safety and function of roads and associated
    infrastructure (e.g., bridges, culverts)” should be considered. Our above analysis under Act 250
    criterion 5 provides such an analysis. Within the narrow prospect of the project’s projected
    impact upon traffic and related infrastructure, we conclude that the project as proposed,
    including the mitigating conditions described above, do not conflict with and are therefore in
    conformance with Act 250 criterion 5 and Zoning Regulations § 5.2(C)(3).
    IV. Fiscal Burdens.
    127.      The Rivers quarry will employ approximately six individuals on site; its employees will
    most likely be individuals already residing in the area. It is unlikely that the quarry will be the
    cause of more than a few individuals moving into the area, and will therefore not be the cause of
    any measurable increase in the need for educational services or other school facilities, or a
    measurable increase in the municipal spending on these educational services.
    128.      Nearly all the providers of area municipal services provided written confirmation that the
    project as detailed to them by Rivers will not exhaust their ability to provide their respective
    municipal services. These “ability to serve letters” were received from officials within the
    Moretown Fire Department, the Mad River Valley Ambulance Service, and the Vermont State
    Police.
    129.      The Harwood Union School District Superintendent of Schools identified no adverse
    impacts or other school deficiencies that would be caused by the Rivers project. This disclosure
    was made on a response form attached to Rivers’ Act 250 application.                  The District
    Superintendent advised that he would not be available to testify in the Act 250 proceedings.
    130.      The most convincing testimony is that the Rivers haul trucks will travel almost
    exclusively over state-maintained highways. Haul trucks will only travel on town highways for
    limited periods of time: to reach the project destinations identified by its customers. In this
    regard, the Rivers quarry will not have a measurable impact upon the municipal expenditures to
    maintain town roads, which is one of Moretown’s highest line item expenses for municipal
    services. The Rivers quarry will not contribute to the degradation of town highways, as is often
    caused by existing quarries that are located in outlying areas and have haul trucks that regularly
    travel over less-improved town highways.
    -35-
    131.   In fact, the close proximity of the Rivers quarry to the Town Highway Garage and
    stockpile area may allow the Town to realize a reduction in the cost of rock product, given that
    the length of transportation significantly contributes to the cost of rock products. The exact
    measure of such cost savings was not credibly offered at trial.
    132.   During a day in which the Rivers quarry generates a maximum number of trips by its haul
    trucks (i.e., 108 one-way trips), the Rivers quarry could increase the number of haul trucks that
    travel over Route 100B in the Village area by nearly 175%: Rivers will generate 108 one-way
    haul truck trips, compared to 62 such truck trips estimated in existing traffic. These calculations
    are premised upon an assumption that all haul-truck trips generated by the Rivers quarry would
    travel south on Route 100B and through the Village area.
    133.   Rivers’ traffic expert estimated that the increase in truck traffic generated by the Rivers
    quarry through the Village area could be as little 21%. Although we conclude that it is unlikely
    that all of the haul-truck traffic generated by the Rivers quarry will pass through the Village, we
    conclude that a mere 21% increase is not credible, especially upon the most relevant comparison:
    the quarry-generated haul-truck traffic as compared to the heavy haul-truck traffic that currently
    passes through the Village.
    134.   Most credible is the estimate of experts that at least 60% of the Rivers quarry haul truck
    traffic will pass through the Village area on Route 100B. While 60% of the maximum quarry
    truck traffic represents a small number (less than 65 one-way haul-truck trips) when compared to
    the estimated pre-quarry traffic through the Village (3,500 one-way vehicle trips per day), this
    estimate of pass-through haul-truck traffic will represent nearly a doubling of similar heavy truck
    trips estimated to now be passing through the Village each day.
    135.   Heavy haul-truck traffic is markedly different that all other traffic, including other truck
    traffic. The impact upon bicyclists and pedestrians in the Village is markedly different when a
    heavy haul truck passes than when a passenger vehicle or even a delivery truck passes.
    136.   The Town offices, Elementary School, and other Village buildings and residences are
    located close to Route 100B in the Village area.
    137.   The Elementary School has two classrooms in the front of its building; they currently
    host the fifth and sixth grade classes. Heavy haul trucks passing by can clearly be heard within
    these classrooms, and they may even cause disruptions.
    -36-
    138.   Noise impacts upon educational activities in these front classrooms have been a cause of
    concern for the School principal, who provided compelling testimony at trial. However, when
    challenged to provide reference for the level of these disturbances, the school principal could not
    cite to a single student or parent complaint having been received since she first became school
    principal in 1995, nor could she cite to a single school board report or meeting where such noise
    complaints were discussed.
    139.   While Town officials expressed several concerns regarding the impact of quarry truck
    traffic as it passes the Town offices and Elementary School, Town Officials did not present
    evidence as to any specific school construction or increase in per pupil spending that the quarry
    traffic would directly cause. The School Principal admitted that she had never advocated for, or
    given any consideration to, physical improvements or planning at the school in response to the
    detrimental noise impact from traffic that passes in front of the school, even though she asserted
    that traffic noise had caused detrimental impacts at the school since 1995.
    140.   One independent measure of noise impacts upon educational settings is derived from the
    American National Standards Institute (“ANSI”), which establishes a 40 decibel (“dB”)
    maximum level for background noise in a classroom. When exceeded, this ANSI standard
    recommends that the background noise be regarded as disruptive to the classroom.
    141.   The current noise background level measured in the two front classrooms of the Town
    elementary school often exceeds the ANSI 40 dB maximum, particularly when the classroom
    windows are open, which often occurs during warm days. There is no air condition system in
    place at the school. This background noise level maximum is often exceeded even when the
    noise readings in the classroom are taken during times when no trucks are passing the classrooms
    on Main Street/Route 100B. When trucks, including heavy trucks in the flow of current traffic,
    pass the classroom, whether the classroom windows are open or closed, the ANSI standard is
    exceeded even further. These noise exceedance levels already occur without the addition of the
    traffic the proposed Rivers quarry would generate.
    142.   The Town offered no recommendations as to measures that could be implemented at the
    Elementary School, or elsewhere by Rivers, to mitigate the impact from heavy haul traffic from
    the quarry that passes in front of the School.
    -37-
    143.   The Town does not presently have in effect a capital improvement program that could be
    considered in these proceedings in relation to the project’s potential impact upon growth and the
    rate of growth under Act 250 criterion 9(A).
    144.   The quarry does not represent a development that will have a direct impact upon, or will
    contribute to, the rate of growth in the region. The only impact of this quarry upon growth and
    rate of growth in the region will be tangential, at best, and only if its proximity to developments
    in the region is closer than other quarries and will therefore reduce the cost of processed rock
    that such outlying developments may use. We regard this impact to be minimal and not material.
    145.   The Rivers quarry is not next to or contiguous to an existing development. However, it
    will not contribute to the costs of scattered development governed by Act 250 criterion 9(H), in
    that it will not encourage the type of development that, due to its isolation from other
    development, contributes to adjoining growth and increases in the costs of public services and
    facilities. No evidence was offered that this quarry development will attract or encourage
    adjoining scattered developments in its vicinity.
    Legal Conclusions as to Fiscal Burdens (Act 250 criteria 6, 7, 9(A), 9(H), and 9(J);
    Zoning Regulations §§ 3.5(C)(2), 4.10(B)(3), and 5.2(C)(1)).
    a.      Act 250 Criteria 6 and 7.
    We have previously combined a review of these Act 250 criteria under a general heading
    of “economic impacts.” In re JLD properties of St. Albans, LLC, No. 129-5-06 Vtec, et. al., slip
    op. at 34 (Vt. Envtl. Ct. Jan. 20, 2010) (Durkin, J.). Such a combined review is appropriate in
    these proceedings, including a combined review with the analogous provisions in the Zoning
    Regulations.
    Act 250 criteria 6 and 7 are often reviewed together due to their common purpose.
    Criterion 6 cautions that a project cannot be allowed if it will cause an “unreasonable burden on
    the ability of a municipality to provide educational services.”           10 V.S.A. § 6086(a)(6).
    Criterion 7 includes an analogous prohibition concerning “the ability of local governments to
    provide municipal or governmental services.” 10 V.S.A. § 6086(a)(7).
    In most Act 250 proceedings, conformance with criteria 6 and 7 is often proved by
    “ability to serve” letters from the affected municipal entities. In these proceedings, officials from
    the departments or entities that provide police protection, emergency services (fire and
    ambulance), and union district middle and high school services have all provided uncontradicted
    -38-
    representations that the Rivers quarry will not unreasonably interfere with their departments’ or
    agencies’ respective abilities to provide such services to the Town and region.            Thus, the
    remaining dispute under criteria 6 and 7 relates to the impact from the quarry upon the ability of
    the Town Elementary School to provide education to its students.
    Criteria 6 and 7 bring a similar allocation of the burdens of proof as does criterion 5:
    while the applicant must present some facts to satisfy its initial burden of production, the burden
    of persuasion and ultimate burden of proof under criteria 6 and 7 rests with the parties opposing
    the project application. 10 V.S.A. § 6087(b). Under each criteria, the opposing parties must
    offer persuasive evidence that the proposed project “will place an unreasonable burden” upon
    local governments’ ability to provide educational and municipal services.              10 V.S.A.
    §§ 6086(a)(6) and (7).
    In regard to the noise impacts of the quarry on the Town Elementary School, there can be
    no dispute that additional heavy trucks passing by on Route 100B will increase the frequency of
    noise disruptions at the school, particularly in the two front classrooms. The existing traffic
    already contributes noise disruptions in excess of the ANSI standards.         In fact, the school
    principal moved her office, which once was in one of the front classroom areas, and testified that
    she did so because of the existing road noise. However, the Town’s response to the current road
    noise distractions tends to prove that existing road noise has not placed an unreasonable burden
    upon the school’s operation. We therefore conclude that the incremental increase in road noise
    that the quarry will bring cannot be regarded as creating an unreasonable burden either.
    Our conclusion here is supported by the lack of complaints received by the school, and
    the lack of discussion at school board meetings that the existing road noise had generated
    material distractions. Our analysis here may have been different if any evidence had been
    provided that school officials had acknowledged and attempted to take corrective action in
    response to the noise distractions from existing traffic, which already exceed ANSI standards.
    Such evidence would have tended to show that the Town had concluded that the expenditure of
    municipal funds was required to address these noise distractions. But we received no such
    evidence. There is therefore no credible foundation for us to conclude that the quarry truck
    traffic, while disruptive, will place or contribute to an unreasonable fiscal burden upon the Town
    Elementary School, or the provision of any other municipal services. The Rivers project is
    therefore in conformance with Act 250 criteria 6 and 7.
    -39-
    b.      Act 250 Criteria 9(A), 9(H), and 9(J).
    Act 250 criterion 9(A) requires us to consider the population growth for the Town and
    region and whether the proposed project would “significantly affect their existing and potential
    financial capacity to reasonably accommodate both the total growth and rate of growth”
    generated in the Town and region generally, and that which the project will generate. 10 V.S.A.
    § 6086(a)(9)(A). Our analysis here is succinct because the Rivers quarry is not the type of
    development that has the capacity to materially contribute to growth or the rate of growth, and it
    is unlikely to affect the Town or region’s financial capacity to accommodate the growth it
    experiences, distinct from the quarry project.          The proposed quarry is not the type of
    development that will encourage other residential or commercial developments in its vicinity;
    that is the type of development that affects growth and the rate of growth from which criteria
    9(A) seeks to protect. There was no credible evidence that the proposed project will directly
    encourage growth or impede the Town or region’s ability to accommodate growth. We conclude
    that the proposed quarry satisfies Act 250 criterion 9(A).
    Act 250 criterion 9(H) is often described as the criterion that protects against “scattered
    development;” it is titled as such. 10 V.S.A. § 6086(a)(9)(H). The premise of this criterion is
    that when scattered residential or commercial development occurs, the host municipality is called
    upon to provide municipal services to this outlying development, thereby increasing the
    municipality’s fiscal burden.    This situation is exacerbated because once the municipality
    provides the infrastructure and incurs the costs of providing those services to these new
    developments outside of or not adjacent to existing settlements, these municipal expansions
    encourage even further development in the outlying areas. Outlying or scattered development
    tends to have a negative domino effect upon municipal expenditures.            Therefore, Act 250
    criterion 9(H) prohibits developments that do not generate sufficient municipal tax revenues “and
    other public benefits” that do not outweigh “the additional costs of public services and facilities
    caused directly or indirectly by the proposed development.” Id.
    There is no dispute that the Rivers quarry is not in or next to an existing development.
    Proposed quarries may be far less likely to succeed in obtaining the necessary land use permits if
    they were. However, by locating outside of the existing settlements in Moretown and the Mad
    River Valley, the Rivers quarry will not bring, directly or indirectly, the added costs of scattered
    development that criterion 9(H) seeks to guard against.         The proposed quarry requires no
    -40-
    municipal services, including water supply or wastewater disposal facilities, to be extended to its
    project site. Its presence in this neighborhood is unlikely to encourage new residential or
    commercial developments to move to this area. The proposed quarry conforms to criterion 9(H).
    Criterion 9(J) seeks to protect against developments that require “supportive
    governmental and public utility facilities and services” that are either not yet available in a
    community, or for which the community has not yet planned. 10 V.S.A. § 6086(a)(9)(J). This
    criterion specifically prohibits projects that will place “an excessive or uneconomic demand” on
    such public facilities or services. Id.
    Other than the general, incremental services that any activity in an area may require, such
    as municipal emergency services, there was no credible offering of evidence that the Rivers
    project would need such public facilities or services. There was certainly no support offered for
    an assertion that the Rivers project will place an excessive or unreasonable demand on needed
    public services. The project conforms to criterion 9(J).
    c.        Zoning Regulations §§ 3.5(C)(2), 4.10(B)(3), and 5.2(C)(1).
    Zoning Regulations § 3.5 provides the standards by which specific rock and gravel
    extraction projects can be permitted; subsection (C)(2) specifically prohibits an extraction project
    that would have an “undue adverse effect on: . . . public facilities and services.” Regulations
    § 3.5(C)(2). As noted above, § 3.5 also imposes an obligation upon any extraction project to
    conform to the general and specific standards for conditional use review found in Regulations
    § 5.2. In subsection (C)(1), a proposed extraction project must meet the general standard of not
    adversely affecting the capacities of existing or planned community services or facilities.
    Regulations § 5.2(C)(1).
    Each of these regulatory provisions mirror the protections afforded to a municipality and
    region under Act 250 criteria 9(A), 9(H), and 9(J). For the same reasons as are expressed above,
    we conclude that the Rivers quarry as proposed conforms to Zoning Regulations §§ 3.5(C)(2)
    and 5.2(C)(1).
    Lastly, Regulations § 4.10 imposes general and specific performance standards for all
    land uses or structures in all zoning districts. Subsection (B)(3) provides that a project shall not
    cause “fire, explosive or safety hazard . . . which significantly endangers other property owners
    or which results in a significantly increased burden on municipal facilities.”         Regulations
    § 4.10(B)(3). We analyze the question of possible endangerment to neighboring property owners
    -41-
    by Rivers’ planned blasting practices in our subsequent discussions under Act 250 criteria 8,
    9(E), and 10. In all other respects, we conclude that the proposed extraction project conforms to
    Regulations § 4.10(B)(3).
    No fires are planned for the Rivers site. Trees and stumpage will be processed or
    disposed of by other means. Hazardous materials will only be brought on site when needed for
    the planned rock blasting; all explosives will be removed from the site and stored off site. We
    were not made aware of any significant increased burden on municipal facilities that the Rivers
    project will cause, save for the on-site blasting practices that we review in subsequent sections of
    this Decision. In all other respects, the Rivers quarry conforms to Regulations § 4.10(B)(3).
    V. Impact Upon Aesthetics, Area’s Natural Beauty, and Historic Sites.
    146.   Route 100B follows the general low-lying areas of the Mad River Valley. For nearly all
    of its six and a half mile distance, Route 100B lies to the east of the Mad River. Hillsides and
    ridgelines stand above the highway on either side as it travels from its junction with US Route 2
    and Interstate 89 from the north, to its terminus at its junction with Route 100, just south of
    Moretown Village.
    147.   Route 100B is a spur off of Route 100, which travels the full length of our State. Route
    100B provides access to the rural settings and sparsely-settled residential areas along its route,
    the Moretown Village area, and (after the junction with Route 100) the recreational resorts
    located in the adjoining towns of Waitsfield and Warren to the south.
    148.   No evidence was provided of any commercial or heavy or light industrial developments
    along the full span of Route 100B, at least until one reaches the Moretown General Store in the
    Village. To the extent that there are commercial or industrial developments in Moretown, they
    are located away from the Ag-Res District and the boundaries of Route 100B.
    149.   Part of the area along Route 100B has been designated a Vermont Byway/Scenic
    Highway corridor. The corridor reaches 300 feet on either side of Route 100B. While a portion
    of the Rivers parcel is within this corridor, the quarry site itself is not. However, the quarry site
    can be viewed from various points within this scenic corridor.
    150.   The area more than earns this scenic designation; it represents one of the most scenic and
    aesthetically charming areas one can travel along a Vermont state highway. Testimony revealed
    that the Route 100B corridor has been recognized as an especially scenic road since at least the
    early 1970s.
    -42-
    151.    The project area and its surrounding neighborhood are particularly scenic. The classic
    “V” shaped valley, the bottom of which hosts the Mad River, is accentuated by the opposing
    ridgelines that run north to south. The Rivers property sits along an area where the land rises
    from Route 100B to the west; the Rivers property faces the opposing ridgeline in a southeasterly
    direction.
    152.    The area that sits along the easterly ridgeline hosts Moretown Common Road and the
    sparsely-spaced residences that run along it. Many of these homes enjoy a view of the area that
    would host the Rivers quarry.
    153.    No opposing home site will observe the entire exposed area of the quarry; many will
    observe some portion of the quarry; some will observe most, but not all of the benches of the
    quarry along its tallest, westerly wall; some opposing residents will view none of the quarry, or
    less than a one-acre portion of the quarry.
    154.    Meadows, pastures, croplands, and residences rise from the river bank and along the
    hillsides adjacent to Route 100B, including in the vicinity of the Rivers quarry.
    155.    Much of the area surrounding the quarry site is forested. About sixteen residences, many
    belonging to the individual neighbors who are parties to these proceedings, are within a half mile
    of the quarry site; about twenty-eight more residences are within one mile of the quarry site.
    156.    The project area has historically hosted farming and forestry activities. Portions of the
    area continue to host these historic uses; several of the current residences are historic
    farmhouses, dating back 100 years or more.
    157.    The project area also hosts several popular recreational sites and activities, including the
    Ward public recreation area and river access site and popular fishing holes directly accessed
    from Route 100B. The State also uses these areas to stock the nearby portions of the Mad River
    with fish for sport fishing.
    158.    Route 100B, for most of its length and particularly in the vicinity of the Rivers parcel, has
    wide paved shoulders that are used by walkers, bicyclists, and “dry” skiers (skies on rollers, not
    requiring snow).
    159.    There are no historical or active quarries within or adjacent to the Route 100B corridor;
    there are no such quarries in the vicinity of the Rivers property.
    160.    There are no uses within any vicinity near the Route 100B corridor that employ blasting
    practices for their respective uses. There are no heavy or light industrial uses that generate any
    -43-
    significant numbers of truck trips, particularly trucks similar to the heavy haul trucks to be
    employed at the Rivers quarry.
    161.     There were no uses identified in the area of the quarry, or anywhere within the Ag-Res
    District, that employ a rock drill, crusher, or sorting machines, nor any mechanism employed in
    the area that would generate similar levels of noise to the equipment that would be employed at
    the Rivers quarry.
    162.     The current uses in the project area, and in all of the Ag-Res District, are predominately
    agricultural, residential, and forestry.
    163.     Four horse farms are located in the vicinity of the quarry, across Route 100B. Two of
    these horse farms, owned by the Sainsbury and McMullin families (both families also live on
    these properties) have indoor and outdoor riding arenas, riding trails and pastures, and provide
    riding lessons and horse boarding services to the general public.
    164.     The initial work at the quarry will include improvements to the access road and
    establishment of the quarry floor and the initial phase of the detention pond. Some blasting of
    rock will be required during these improvements, including along Route 100B, so that the
    northerly sight distances are increased.
    165.     Once general quarry operations begin, extraction activities would proceed along a pattern
    that follows a traditional process for extracting rock. This involves stripping soil and overburden
    with excavation equipment, drilling holes into the rock mass, loading and stemming light
    explosives, and detonating those explosives in a series of controlled delays as part of a single
    blast.
    166.     There was much dispute during trial as to how the blasts would be planned, orientated,
    and drilled. Planning blasts is as much an art as it is a science; there are many variables to be
    considered, including orientation of the rock wall to be blasted; number of holes to be drilled; the
    number of rows of drilled holes and how many holes should be drilled in each row; the
    alignment of the rows of drilled holes; the need to track a drill bit, so as to avoid it straying from
    the planned alignment of the hole; the amount of explosives to be placed in each blast; whether
    PVC piping needs to be used to avoid the flow of explosives into rock fragmentation that may be
    intercepted by the drilled holes; and the time that each explosive detonation may need to be
    “delayed,” so as to plan the most efficient blasting of the rock.
    -44-
    167.   Blasted rock generally flies up into the air and settles on the quarry floor. Sometimes, the
    rows of drilled holes in which the delayed explosives are placed are aligned in a wide “V”
    formation, so that the blasted rock is thrown against itself and further broken up. Sometimes,
    rock is thrown beyond the quarry floor area; on rare occasions, blasts will cause rock to fly
    beyond the boundaries of the quarry site. While most all blasted rock is thrown up in the air, the
    term “fly rock” is often used to refer to the rare, dangerous, unintended occurrences at some
    quarries in which projectiles of rock are thrown beyond the designated quarry areas and
    sometimes onto neighboring properties.
    168.   Fly rock beyond a quarry’s boundaries rarely occurs because it is never intended by the
    blaster or the quarry operator. To cause rock, sometimes large rocks, to be blasted beyond a
    quarry’s boundaries results in the energy from detonated explosives being used to throw rock an
    unintended distance, rather than being devoted to the break-up of the rock; it represents energy
    from the blast being wasted.
    169.   While fly rock that travels onto adjoining properties is rare, when it does occur, it can
    cause physical injury and property damage. At trial, credible testimony and other evidence was
    offered by Mr. Hendrickson, and corroborated by Rivers’ blasting expert, tending to show that
    outer-boundary fly rock has occurred in several quarries within a fifty mile radius of the Rivers
    property. Such fly rock at one quarry damaged one or more homes; fly rock at the quarry near
    the airport in West Lebanon, New Hampshire, caused extensive damage to personal vehicles and
    other property at the airport. In these instances, fly rock traveling in excess of 1,500 feet was
    corroborated by Rivers’ expert.
    170.   Rivers’ expert credibly maintained that a properly planned and executed blast will not
    result in fly rock beyond the boundaries of the Rivers property; the expert maintained that most
    or all blasted rock from properly planned and executed blasts would not travel beyond the limits
    of the quarry floor.
    171.   However, Rivers’ expert could not assure that no blasts at the Rivers quarry would result
    in rock being thrown beyond the Rivers’ boundary limits. He speculated that rock could be
    thrown, unintentionally, as far as 1,500 feet from the quarry floor. Because some homes are
    located within this distance, he recommended that area residents be notified prior to a blast and
    that they stay in their homes during a blast.
    -45-
    172.    Rivers’ blasting expert also recommended, in response to concerns about fly rock, that
    the blasts at the Rivers quarry be orientated away from Route 100B and the nearby residences
    “as much as possible.” Blasts generally throw the blasted rock in a direction perpendicular to the
    row of drilled holes, with a deviation of up to forty-five degrees.
    173.    While we found this recommendation responsive to the expressed concerns, we cannot
    understand how all or even a significant minority of the blasts at the quarry site could be
    orientated away from its neighbors and Route 100B. The site slopes significantly towards Route
    100B; no quarry activities are planned on the other side of the ridgeline on the Rivers parcel.
    While some planned quarry faces are perpendicular to and even face opposite Route 100B, the
    most significant quarry face, where the majority of the blasting will occur, faces Route 100B.
    Once quarry operations are completed in 33 years, this blasted face and its resulting quarry
    benches will rise 210 feet above the quarry floor. No other quarry face will experience the
    blasting that this northwesterly face will experience.
    174.    When a blast occurs, the delays between the detonations of explosives in each hole will
    be measured in small fractions of a second. The delays are so minute in sequence that the human
    ear will only recognize their combined detonation as a single blast. It is for this reason that the
    individual detonation of explosives in each hole, sometimes more than sixty in number, is often
    referred to as a single blast. These combination blasts will be significant enough to be heard off
    site.
    175.    Generally, noise and the impact upon individuals’ hearing is measured in decibels.
    Sound levels detectable by unassisted human hearing are typically measured on a weighted “A”
    scale (“dBA”), with 0 dBA being the threshold of human hearing and 135 dBA being the level at
    which the noise causes pain and physical damage to the human ear.
    176.    Sound is measured on a logarithmic scale; its level rises exponentially as its measurement
    increases. For example, sound measured at 65 dBA is twice as loud as sound measured at 55
    dBA.
    177.    Current traffic along Route 100B creates background noise measured by each party’s
    noise expert as at or exceeding 55 dBA at some nearby residences.
    178.    The quarry operations will cause a variety of noises to be created and heard at the nearby
    residences, along Route 100B, and at the nearby recreational and fishing sites. These noise
    sources include the blasting, crushing, and sorting of rock; rock drilling; operation of excavation
    -46-
    equipment; haul trucks, including those operating on the quarry floor and up and down its access
    road; and the loading of processed rock by excavators into the empty metal beds of single- and
    multi-axle haul trucks. None of these types of quarry activity noises currently exist in the
    neighborhood.
    179.   The experts disagreed on the proper measurement of noises originating from the quarry.
    There was some general agreement, offered on different terms, that some quarry activity will
    cause noise to be heard at the Rivers property line in excess of 70 dBA and at the nearest
    residences in excess of 55 dBA.       These estimates of quarry noise are separate from the
    measurement of existing background noise, which sometimes also exceeds these levels.
    180.   Different noises, even when at the same measured dBA level, can be differentiated by the
    human ear.    Birds chirping at the same level as highway noises are distinguishable; rock
    dropping into a metal haul-truck bed, as well as the variety of noises emanating from the quarry,
    are distinguishable from equally loud traffic and other background noises.
    181.   In terms of noise mitigation measures on the Rivers quarry site, the existing vegetation
    that will remain undisturbed by quarry operations will provide some shielding to dissipate noise.
    However, the tree and vegetative cover is thin in places on the Rivers property, including in the
    areas between the quarry site, Route 100B, and the nearest residences. Also, since the quarry is
    proposed to operate from April 15 to December 15 each year, there will be months of operation
    when the intervening trees and vegetation will be leafless.
    182.   Rivers also proposes to use temporary noise barriers that will be re-orientated as quarry
    operations progress to place it between the drilling and crushing equipment, Route 100B, and the
    neighboring properties. Rivers’ experts referred to these temporary noise barriers as their “kit of
    parts,” since the “kit” would include a variety of placards and other pieces to be employed to
    construct shields from quarry noise sources. In any event, the parties’ noise experts took into
    account, to a varying degree, the mitigation that the vegetation and kit of parts would effectuate
    when they arrived at the noise level estimates in Finding 179 above.
    183.   The noise measurements also took into consideration that all equipment operating at the
    Rivers quarry would employ exhaust mufflers and other noise reduction measures required by
    federal regulations.
    184.   When blasting, rock extraction, and reclamation is completed, which Rivers estimates
    will take thirty-three years, the quarry site will be visible from several locations along Route
    -47-
    100B, Moretown Common Road, and other locations in the neighborhood. No immediately
    adjacent homes will be able to see the excavated portions of the quarry due to the steep
    topography and tree cover in the immediate area. The most prominent views of the quarry will
    be from homes and properties of a mile or more away.
    185.      From these distant properties, portions of the completed quarry will be visible, but no
    view of the whole quarry will be available from any of these locations. The parties vigorously
    disputed the measure and offensiveness of the view of the quarry from any number of off-site
    locations. The only clear evidence was that some, but not all of the quarry would be visible from
    one or more miles away.
    186.      The trees near the edge of the quarry would continue to grow; some are nearly sixty feet
    tall and will grow taller. As soon as quarry and reclamation operations cease, the area will begin
    to be revegetated. These trees and vegetation will obscure the off-site partial views of the
    quarry.
    187.      Vermont is a rocky place; rock ledge can be viewed in many places along Route 100B,
    Interstate 89, and along town highways. When viewed from distances of a mile or more, the
    details of even 200-foot-tall ledge expanses are somewhat obscured.
    188.      The ledge at the completed Rivers quarry will not be fully visible from any location. In
    most locations, only a small portion of the seventeen-acre site will be visible. Many area
    residents will have no view of the quarry; some will only be able to view a small portion of the
    quarry, estimated to be less than one acre of the exposed portion of the quarry.
    189.      The quarry site does not contain any buildings or structures; no stone walls, cellar holes,
    of other evidence of historical significance were identified on the Rivers parcel.
    190.      The Division of Historic Preservation of the Vermont Department of Housing and
    Community Affairs is the state agency responsible for identifying historic or archeological
    properties that are either listed on, or are eligible for, inclusion in the State or national Register
    of Historic Places. The Division conducted an on-site field inspection of the Rivers parcel; it did
    not identify any such historic places or artifacts.
    -48-
    Legal Conclusions as to Impacts Upon Aesthetics, Area’s Natural Beauty, and Historic
    Sites (Act 250 criterion 8; Zoning Regulations §§ 3.5(C)(1), 3.5(C)(4), 4.10(B)(1),
    4.10(B)(2), 4.10(D)(6), and 5.2(C)(2)).
    a.      Act 250 Criterion 8.
    An Act 250 applicant must present convincing evidence that the proposed project “will
    not have an undue adverse effect on the scenic or natural beauty of the area, aesthetics, historic
    sites or rare and irreplaceable natural areas.” 10 V.S.A. 6086(a)(8). Once this initial burden of
    production has been met, the burden of proof rests with the opposing parties to show that the
    proposed project will have the undue adverse effect that criterion 8 seeks to protect. 10 V.S.A.
    § 6088(b). This criterion has faced some of the most vigorous inquisition and analysis, both
    before the former Environmental Board and our Supreme Court; the cause of this detailed
    scrutiny is the nature of its inquiry: whether a proposed project “fits” into its surrounding
    environment.
    The relative subjectivity of criterion 8 has even been the basis of constitutional attacks,
    including that this criterion is “so vague that it violates the Due Process Clause” of the United
    States Constitution and that it amounts to an improper delegation of power by our Legislature,
    based upon an assertion that “Act 250 provides no intelligible standards for interpreting the
    subjective concepts of ‘undue adverse effect,’ ‘scenic beauty’ and ‘aesthetics.’” Re: Brattleboro
    Chalet Motor Lodge, Inc., No. 4C0581-EB, Findings of Fact, Conclusions of Law and Order at 5
    (Vt. Envtl. Bd. Oct. 17, 1984). 12
    The former Environmental Board rejected these constitutional challenges. In so doing,
    the Board noted that the standards employed by Act 250 provide sufficient notice and guidelines
    to be deemed constitutional.         While it relied upon a thorough analysis of the due process
    requirements employed by our Supreme Court, the Board summarized the basis for its legal
    determination of constitutionality with vernacular interpretations of the terms “undue” and
    “adverse”:
    The term “undue” generally means that which is more than necessary -- exceeding
    what is appropriate or normal. The word “adverse” means unfavorable, opposed,
    hostile. "Scenic and natural beauty" pertain to the pleasing qualities that emanate
    from nature and the Vermont landscape. In short, through Criterion 8 the
    Legislature has directed that no project within our jurisdiction be approved if it
    12
    The applicant’s name here is somewhat misleading; the proposed project was not in Brattleboro. Rather, the
    project was proposed to be located in Williston, along Interstate 89.
    -49-
    has an unnecessary or inappropriate negative impact on the enjoyment of
    surrounding natural and scenic qualities. Criterion 8 is, therefore, sufficiently
    specific to constitute a proper delegation [of power, as prescribed by the U.S.
    Constitution].
    Id. at 6.
    The Brattleboro Chalet decision, while nearly twenty-six years old, provides precedent
    that remains authoritative and particularly relevant to the case at bar. The Brattleboro Chalet
    applicant sought to place a 103-room motor lodge, with amenities, within 200 feet of Interstate
    89, in an area that was then acknowledged to be a scenic corridor. While similar commercial
    structures existed along I-89, none existed in this particular section of the highway.            The
    applicant proposed to use a design that was similar to its other motels, but one that it did not
    intend to modify for alignment with the scenic qualities of its proposed location. Id. at 7–10.
    The Board described the structure as “a large rectangular monolith, the design of which
    has not taken into consideration the unique features of the site, the character of the land
    surrounding the site, or the scenic qualities of the general area.” Id. at 10. The Board went on to
    describe how landscaping could have “softened” the building, but that its mass and alien design
    could not be “effectively screened.” Id. The signage and lighting proposed by the applicant, the
    Board concluded, would further alienate the building from its surroundings, thereby interfering
    with a visitor’s “enjoyment of the area.” Id.
    The Board concluded that the motel structure proposed in Brattleboro Chalet would be
    “an intrusion on the scenic enjoyment of the traveling public,” basing its conclusion, in large
    part, on the designation of this section of interstate highway as a “scenic corridor.” Id. at 11. In
    light of this “intrusion,” the Board concluded that “that the project will have an undue adverse
    impact upon the aesthetics and scenic and natural beauty of the area.” Id.
    These conclusions appear applicable and analogous to the legal issue before us now, even
    in light of the twenty-six year time span.
    Brattleboro Chalet may be one of the origins of the Board’s detailed analysis under
    criterion 8, but it is not the most often cited. A year later, and after citing the precedent of
    Brattleboro Chalet, the Board provided a more detailed explanation of the analysis criterion 8
    requires; this analysis has been relied upon so repeatedly that it gained a title, founded on its case
    name: the Quechee analysis. See Re: Quechee Lakes Corp., Nos. 3W0411-EB and 3W0439-EB,
    Findings of Fact, Conclusions of Law and Order (Vt. Envtl. Bd. Nov. 4, 1985).
    -50-
    As the Neighbors here suggest, while the Quechee analysis is often remembered for its
    oft-quoted two part analysis, the rationale for adopting this analysis was more succinct: the
    Board concluded that “the cornerstone [of an analysis under criterion 8] is the question: will the
    proposed project be in harmony with its surroundings—will it ‘fit’ the context within which it
    will be located?” Id. at 18.
    The Board reached this conclusion after having received testimony from experts
    presented both by the project proponents and project opponents, in addition to hearing from
    experts the Board itself had retained.     Id.     The Board noted that it was “struck by the
    commonality of understanding by [architecture and landscape design] professionals . . .
    concerning the considerations one applies in evaluating the aesthetic impacts of new
    developments. Our approach to aesthetics analysis is based upon this common understanding.”
    Id. at 17–18.
    The Board then went on to provide guidelines as to how an “undue adverse impact” may
    be assessed for an individual project. First, the Board provided guides as to how a determination
    could be made as to whether a project would have an “adverse impact”; the Board offered five
    specific guides, as well as several general guides for determining whether a project will bring
    adversity to an area:
    Several features must be evaluated in answering this question:
    1) What is the nature of the project's surroundings? Is the project to be located in
    an urban, suburban, village, rural or recreational resort area? What land uses
    presently exist? What is the topography like? What structures exist in the
    area? What vegetation is prevalent? Does the area have particular scenic
    values?
    2) Is the project’s design compatible with its surroundings? Is the architectural
    style of the buildings compatible with other buildings in the area? Is the scale
    of the project appropriate to its surroundings? Is the mass of structures
    proposed for the site consistent with land use and density patterns in the
    vicinity?
    3) Are the colors and materials selected for the project suitable for the context
    within which the project will be located?
    4) Where can the project be seen from? Will the project be in the viewer’s
    foreground, middleground or background? Is the viewer likely to be
    stationary so that the view is of long duration, or will the viewer be moving
    quickly by the site so that the length of view is short?
    5) What is the project’s impact on open space in the area? Will it maintain
    existing open areas, or will it contribute to a loss of open space?
    -51-
    All of these factors must be weighed collectively in deciding whether the
    proposed project is in harmony with—i.e., “fits”—its surroundings. The land
    uses which surround a project are crucial to the analysis.
    ...
    The expert witnesses agreed that certain types of land forms are especially
    sensitive to change, because these land forms tend to be visible from a wide area
    or they are seen by large numbers of people. These sensitive areas include
    ridgelines, steep slopes, shorelines and floodplains. Other features are sensitive
    because they are aesthetically unique; examples may include historic structures,
    wetlands and natural areas. In evaluating a project proposed in a sensitive area,
    the Board and District Commissions should give special attention in assessing
    whether the scenic qualities of these sites will be maintained.
    Id. at 18–19 (emphasis in original). 13
    The Board next noted that if the evidence did not support a finding of an adverse impact,
    the analysis under criterion 8 must result in a positive finding. However, if an adverse impact
    was evident, the Board directed that a determination must next be made as to whether the
    adverse impact was undue. In rendering a determination on this second step of the Quechee
    analysis, the Board provided the following three guiding principals:
    1)       Does the project violate a clear, written community standard intended to
    preserve the aesthetics or scenic, natural beauty of the area? Such
    standards may, for example, be set forth in the local or regional plan, or be
    adopted in the creation of an historic design district, or be incorporated
    into a municipal or State scenic road designation. If the Board or
    Commissions find that such standards do exist, and that the project as
    designed would violate those standards, the adverse impact would be
    undue.
    2)       Does the project offend the sensibilities of the average person? The
    Legislature has directed the Commissions and this Board, composed of lay
    people from many different communities within Vermont, to determine
    what is acceptable in terms of new developments’ impact on aesthetics
    and scenic and natural beauty. If our sensibilities are, collectively,
    offended by a project, its impact under Criterion 8 is undue. It is not
    enough that we might prefer to see a different design or style of building,
    or that we might prefer a different type of land use, but that the project,
    13
    The Board Decision cited here is most often referenced as the origin of the Quechee analysis. However, the
    Quechee Lakes project had a long and somewhat tortured history before the former Environmental Board and the
    Supreme Court. The Board’s 1985 Decision concerned an application to expand the Quechee Lakes project; the first
    Act 250 permit was issued by the District 3 Environmental Commission in a prior proceeding. No party chose to
    appeal the Board’s 1985 Decision. However, a later permit amendment proceeding, necessitated by unpermitted
    revisions to the design of the Quechee Lakes buildings, was the subject of an appeal to the Vermont Supreme Court.
    See In re Quechee Lakes Corp., 
    154 Vt. 543
     (1990). The Supreme Court in those proceedings affirmed the Board’s
    analysis of undue aesthetic impacts of the unpermitted improvements at the project. 
    Id.
     at 551–57.
    -52-
    when viewed as a whole, is offensive or shocking, because it is out of
    character with its surroundings, or significantly diminishes the scenic
    qualities of the area.
    3)      Has the Applicant failed to take generally available mitigating steps which
    a reasonable person would take to improve the harmony of the proposed
    project with its surroundings? Such steps may include selection of less
    obtrusive colors and building materials, implementation of a landscaping
    plan, selection of a less obtrusive building site within the project area, or
    reduction of the mass or density of a project. If there are reasonable
    alternatives available to the Applicant that would mitigate the adverse
    impact of the project, failure to take advantage of those alternatives may,
    in some circumstances, render undue an otherwise acceptable aesthetic
    impact.
    
    Id.
     at 19–20.
    Thereafter, the Board again cautioned that the primary purpose of an analysis under
    criterion 8 is whether a proposed project is “in harmony” with its surroundings; whether it will
    “fit.” Id. at 20.
    For the reasons expressed in more detail below, based upon the Findings of Fact detailed
    above and below in our analysis of criterion 10 (town plan), we conclude that the proposed
    Rivers quarry would not “fit” into its surrounding area, which has been designated and is actively
    used as a scenic resource, and will therefore bring an undue adverse impact upon this area. The
    proposed quarry does not conform to criterion 8.
    The noises and activity that the proposed quarry will bring to this area will be unique;
    they are not currently experienced in any fashion within the Ag-Res District and along the scenic
    corridor that is Route 100B. Interestingly, when the former Environmental Board reviewed the
    area of Williston in which Brattleboro Chalet proposed its development in 1984, the Board noted
    that there were already similar commercial developments not far from the project site. See
    Brattleboro Chalet, No. 4C0581-EB, at 8–9. However, these nearby, preexisting commercial
    developments did not dilute the undue adverse impact the proposed motel would have, in the
    Board’s analysis, upon the scenic area in which it was sited. This legal analysis makes the
    hurdle for the Rivers quarry even more substantial, given that Rivers must concede that no
    similar commercial activities exist anywhere near its project site.
    Route 100B is a rural major collector highway, but its route has been designated a scenic
    corridor. The area has historically hosted residential and agricultural activities and continues to
    do so to this day. Some forestry activities have also occasionally occurred on the project site and
    -53-
    in the area, but forestry brings minimal intrusion into a residential or agricultural setting. It often
    occurs on an individual parcel once in only twenty years or so. When forestry activities do
    occur, they are often of a short duration; we have not been made aware of any instance in which
    forestry activities occurred in any area, and particularly in this area, for more than a matter of
    months. The Rivers quarry is proposed to continue in operation for thirty-three years.
    While highway noises from the traffic on Route 100B can be regularly heard in the area,
    there is a certain commonality and regularity to this traffic noise; it becomes less intrusive as it
    occurs and becomes background noise for area residents and visitors. True, some traffic noise
    registers at or above levels established in prior Board decisions and the applicable zoning
    regulations (70 dB at the boundary line; 55 dB at a residence), but to the extent Rivers argues
    that this level of background noise makes the noises at those levels from the Rivers quarry less
    intrusive, we reject that argument.
    The noises emanating from the quarry at regular intervals will exceed the established
    maximums at both the property line and at the nearby residences. But that is not the sole
    determining characteristic for the noises generated at the quarry site; the quarry will bring to this
    neighborhood, already deemed scenic and residential/agricultural in character, noises completely
    foreign and not presently experienced in this region.
    The former Environmental Board most recently addressed the impacts of a proposed
    quarry in the case of McLean Enterprises Corp. In reviewing the impacts of this proposed quarry
    operation, the Board rendered Findings and Conclusions that we find appropriate for the case at
    bar and the impacts the Rivers quarry will have upon its neighborhood:
    142.    An operational quarry generates noise from sources such as rock crushers,
    rock drills, blasting, moving trucks. These sources generate loud sounds
    that do not blend in with any natural environment. Examples of
    instantaneous noises that may originate from a quarry are the noises
    generated by dropping, crushing, blasting, moving, and drilling rock.
    143.    The expected noise from the Project is markedly different than the existing
    rural context of this area. The sounds that would be generated by the
    Project would be impulsive and more like industrial sounds than anything
    now part of the background of the area. The noises would be harsh and
    intermittent, unlike the usual sounds experienced in a rural setting and not
    merely louder versions of the same noises already present.
    Access Road Construction and Hillside Quarry
    144.    This Project's noise issue is compounded by [the fact that] . . . the access
    road is a steep winding road which will require the trucks to go up and
    -54-
    down in low gears and also use engine brakes (colloquially referred to as
    “jake brakes”) to control speed on the descent.
    Re: McLean Enters. Corp., No. 2S1147-1-EB, Findings of Fact, Conclusions of Law and Order
    at 23–24 (Vt. Envtl. Bd. Nov. 24, 2004).
    While the Rivers access road may not be winding, testimony revealed that it is steep and
    that the haul trucks descending the access road, and trucks on Route 100B decelerating to turn on
    to the access road, will occasionally be downshifting and using jake brakes, a practice Rivers did
    not significantly dispute. While this neighborhood hosts a rural major collector highway (Route
    100B), these trucking noises do not occur with as much frequency as will occur if the Rivers
    quarry is allowed to operate. Credible estimates of heavy truck traffic suggest that the Rivers
    quarry could double the number of heavy trucks traveling from the quarry and through the
    Village on Route 100B.
    We also concur with the Board in its McLean Enterprises Decision that when quarry
    noises will be so new and foreign to an existing area, the quarry noises will be a recognizable
    intrusion into the scenic setting. This will even be true in the Rivers neighborhood, which is
    bisected by Route 100B. The area is known for its scenic beauty and tranquility; it is used by
    bicyclists, walkers, pavement skiers, fisherman, swimmers, and those simply enjoying a lazy
    float down the Mad River. The noises emanating from the quarry, most of which will be at or
    above the sound levels of the background traffic noises, will be a disruption of and intrusion
    upon the neighbors’ and visitors’ enjoyment of this scenic area. So too will the increased
    frequency of heavy truck traffic, including in the Village area. All these quarry activities will
    represent an adverse impact upon the Rivers neighborhood, and the scenic corridor of Route
    100B; the increased truck traffic through the Village, particularly when predicted to double the
    heavy haul trucks traveling though that narrow strip of Route 100B, will also have an adverse
    impact upon its residents, school children, and school administrators.
    We are less inclined to characterize the distant views of a portion of the quarry as
    intrusive and of an adverse impact. No area resident will have a full view of the exposed portion
    of the quarry; most will have a view of only a small portion of the quarry; some (including the
    quarry’s closest neighbors) will have no view. Natural rock outcroppings and rock walls left
    from drilling and blasting are seen everywhere in Vermont; they are a constant reminder of the
    predominant nature of what lies beneath our soils. We found Rivers’ depictions of the distant
    views of the exposed rock walls within the quarry more credible than those offered by the
    -55-
    opposing parties. In the abstract, and without the ability to be disturbed by the on-going quarry
    noises, the view alone of the quarry does not constitute an adverse impact.
    Because we have concluded that the quarry activities will have an adverse impact, we
    next consider whether it is undue. Our determination is guided by the three standards from
    Quechee cited above (written community standard, sensibilities of the average person, generally
    available mitigating steps). First, we note the scenic corridor designation along a 300-foot wide
    expanse along either side of Route 100B. A portion of the Rivers parcel lies within this corridor.
    While the quarry site itself is outside this corridor, the noise and activity originating at the quarry
    will be heard and felt within the scenic corridor.           The quarry will contradict the very
    characteristics that brought the scenic designation upon this area; it will offend an average person
    visiting the area, expecting to enjoy its scenic quality, but not anticipating the noises emanating
    from the drilling, blasting, crushing, and loading of rock at an adjacent quarry.
    We conduct below, in our legal conclusions regarding criterion 10 and conformance with
    the Town Plan, an analysis of the proposed quarry’s conformance with the overall standards in
    the Moretown Town Plan.         We conclude that it does not conform to the most applicable
    standards. In fact, while it is indisputable that earth extraction may be allowed as a conditional
    use in the Ag-Res District, we are at a loss to find another expressed community that supports the
    Rivers quarry as proposed. When coupled with the offense to someone expecting to experience
    the scenic qualities espoused for the region, we conclude that the quarry activities and the noises
    emanating from it constitute an undue adverse impact.
    A further small influence upon our analysis here is the number of parties that have
    expressed sincere opposition to the quarry in these proceedings. The Town and those Neighbors
    represented by counsel have presented detailed and multi-layered attacks upon the quarry and the
    activities it would bring to their neighborhood.        Other neighbors, including Mr. and Mrs.
    Hendrickson, articulated specific, sincere concerns regarding the effects that the quarry would
    bring to their neighborhood.
    When our Supreme Court was reviewing the propriety of the former Environmental
    Board’s determination that a proposed RV campground along the banks of the White River
    constituted an undue adverse impact, the Court was quick to defeat an attack on the Board’s
    application of the “second inquiry” under Quechee that was based upon an assertion that “there
    was no general public outcry against the project.” In re McShinsky, 
    153 Vt. 586
    , 592 (1990).
    -56-
    The Court concluded that no such showing was necessary to satisfy the “offense to the
    sensibilities of the average person” test for whether a project’s adverse impact is “undue” under
    Quechee. 
    Id.
     While we do not solely rely upon it for our determination here, we note that the
    Neighbors were universal in their opposition, and they stated their concerns with credibility.
    Rivers did a commendable effort at presenting somewhat convincing evidence of how the
    quarry would be shielded by trees and vegetation that it would leave undisturbed, and how
    equipment mufflers and its “kit of parts” could be used to mitigate the quarry’s impacts. But we
    conclude that these efforts will not be sufficient to diffuse the quarry’s impacts below the level of
    an undue adverse impact upon this scenic area. We were not made aware of further mitigation
    efforts that could sufficiently offset the quarry’s impacts. This development, at this level of
    drilling, blasting, crushing, and trucking, simply cannot “fit” within this scenic area. It fails
    under criterion 8.
    b.         Zoning Regulations §§ 3.5(C)(1), 3.5(C)(4), 4.10(B)(1), and 5.2(C)(2)).
    The provisions within Regulations § 3.5 pertain specifically to earth resource extraction
    projects; subsections (C)(1) and (C)(4) direct that approval should only be provided for such
    projects that will not have an undue adverse effect upon “neighboring properties and uses” and
    “the scenic or natural beauty of the area, other aesthetic values, . . . or rare or irreplaceable
    natural resources or areas.” Regulations § 3.5(C)(1), (4). Our prior analysis shows that the
    Rivers project fails to meet these standards.           The proposed quarry does not conform to
    Regulations §§ 3.5(C)(1) or 3.5(C)(4).
    Pursuant to Regulations § 3.5(A), an earth extraction project must also satisfy the
    conditional use standards, which are found in § 5.2. Regulations § 5.2(C)(2) requires that the
    proposed project not have an adverse effect upon the character of its surrounding area. We have
    already concluded that the proposed quarry will commit this error; the project does not conform
    to § 5.2(C)(2).
    Regulations § 4.10 establishes performance standards for all land uses or structures
    within Moretown; subsection (B)(1) prohibits “noise which is excessive at the property line or is
    incompatible with the reasonable use of the surrounding area.”           Regulations § 4.10(B)(1).
    Perhaps anticipating the need for guidance in determining when noise is “excessive,” the
    provision was drafted to direct that “[e]xcessive noise shall be considered a sound pressure level
    that exceeds 70 decibels at the property line on a regular or recurring basis.” Id.
    -57-
    Rivers concedes that its quarry operations will exceed 70 dBA; it counters that traffic
    from Route 100B and other area noises often exceed this sound pressure level, and that therefore
    its quarry should be found to conform to Regulations § 4.10(B)(1). This argument may have
    merit were it not for the fact that the noises from the Rivers quarry will be so out of character
    with the scenic area. These industrial-type noises will be readily distinguished from the noises
    that accompany this scenic setting, even when the background traffic noises are factored. The
    quarry noises will be incompatible with this neighborhood; the quarry does not conform to
    Regulations § 4.10(B)(1).
    VI. Impact Upon Necessary Wildlife Habitat and Endangered Species.
    191.    There was no evidence presented that tended to show that the Rivers parcel was host to
    any rare, threatened or endangered species or significant natural wildlife communities.
    192.    The ANR Department of Fish and Wildlife, as part of its administrative responsibilities,
    produces and maintains maps to indicate where rare, threatened, or endangered species or
    significant natural wildlife communities are located; no Department maps evidenced such
    wildlife or endangered plants or animals at the Rivers site.
    Legal Conclusions as to Impacts Upon Necessary Wildlife Habitat and Endangered
    Species (Act 250 criteria 8(A)).
    A party opponent may defeat a proposed project when they can show that it “will destroy
    or significantly imperil necessary wildlife habitat or any endangered species.”           10 V.S.A.
    § 6086(a)(8)(A). Even when such a showing is made, an applicant may still overcome a negative
    finding under criterion 8(A) by making certain showings that could mitigate the impact upon the
    necessary wildlife habitat or endangered species on the site. 10 V.S.A. §§ 6086(a)(8)(A)(i)–(iii).
    We need not delve into that analysis, however, since there has been no showing of necessary
    wildlife habitat or endangered species on the Rivers parcel. The project conforms to criterion
    8(A).
    VII. Impact of the Proposed Extraction of Earth Resources.
    193.    The principal impacts to the environment and the surrounding land uses will come from
    the operational phase of the quarry. These will involve the drilling, blasting, crushing, sorting,
    and transporting of rock within and from the quarry site. Our prior Findings address the details
    of all aspects of the quarry construction and operation.
    -58-
    194.      Once the quarry is fully operational, Rivers expects to produce 75,000 cubic yards of
    processed rock. Ten to twelve blasts are expected to be required to produce this volume of rock
    from the Rivers quarry. At this rate during the operational year, one blast will occur every few
    weeks. Drilling will need to occur for about five straight days to prepare for each blast. Thus,
    drilling could occur as frequently as every other week, for consecutive days at a time, and then
    followed by a combined blast.
    195.      Rivers expects each blast to require sixty-two holes to be drilled. Some blasts may
    require more holes to be drilled. Each hole will be about 3.5 inches in diameter and forty-two
    feet deep. A conventional blast plan shows that the rows of drilled holes will be within an eight-
    foot by nine-foot grid.
    196.      The first row of holes for each blast will often be drilled about eight feet from the face of
    rock to be blasted. Subsequent rows will be drilled with an eight-foot separation between each
    row. This distance will help minimize the potential for rock to fly beyond the quarry floor and
    beyond the boundaries of the Rivers parcel. Fly rock that has caused damage to neighboring
    properties has sometimes resulted from the initial row of drilled holes being much closer to the
    rock face, and from rows of holes being drilled closer to each other.
    197.      Fly rock traveling beyond a quarry limits or boundaries has also occurred when too much
    explosive has been loaded into one or more holes. This can occur unintentionally when the
    explosives being poured 14 into a hole seep into fragments in the rock and stray from the drilled
    hole. Rivers suggested that this straying of explosives could be minimized by using PVC piping
    as a sleeve that is inserted into the drilled hole. It was unclear from the trial testimony how
    regularly Rivers was committing to follow this practice, other than to follow it when on-site
    inspections of employees suggest. Rivers pledges to use hole liners in the holes in the front row
    of each blast plan.
    198.      Rivers also proposes to carefully measure the amount of explosives that is poured into
    each hole, either while it is pumped from a delivery truck or poured from pre-mixed bags. Each
    hole will receive a maximum of 128.2 pounds of explosives. Thus, for a 62-hole detonation, a
    combined blast could expend as much as 7,848.4 pounds of explosives.
    199.      Blasts will represent a series of detonations, each separated by a small fraction of a
    second. The detonations will be arranged in sequence, with the first row of hole explosives
    14
    Quarry blasting explosives are most often in a powered form.
    -59-
    being detonated simultaneously, and each row thereafter being detonated a small fraction of a
    second thereafter. The detonations are so close together that they are recognized by the human
    ear as a single blast.
    200.    There are two other consequences of these delayed, sequenced blasts. First, the delays
    increase the frequency with which rock pieces collide and break apart, thereby increasing the
    efficiency of the blast. Second, the combined blast, often recognized as just a single blast, is
    more equivalent to the sound and consequence of expending 128.2 pounds of explosives, and not
    the combined total of explosives expended in each delayed row of holes. This effect will occur
    provided that the detonation of rows is separated by about eight milliseconds (i.e., eight
    thousandths of a second).
    201.    These parameters for planned blasts, when followed, result in the most efficient use of the
    explosive materials and the least opportunity of fly rock to leave the quarry site and the Rivers
    parcel. However, even Rivers’ blasting expert conceded that no blasting plan can guarantee that
    a blast will not cause rock to fly onto neighboring property. It is for this reason that Rivers’
    blasting expert recommended that any resident or visitor within 1,500 feet of the quarry during
    blasting operations remain indoors until after the blast is completed and all fly rock has settled.
    202.    Blasts at the quarry will present two types of shock waves within the quarry and onto
    neighboring properties: ground vibrations and airborne shock waves. The level at which these
    shock waves will be recognized by the quarry’s neighbors and their visitors was subject to great
    dispute, but there was no dispute that some ground vibrations and airborne shock waves would
    be recognized off site.
    203.    Rivers plans to reclaim the quarry site in a series of phases, much like its blasting and
    extraction plan. Once the valuable rock in a phase of the quarry is fully excavated, and after
    quarry operations move into another phase, Rivers will begin its planned reclamation work in the
    completed phase. At no time will more than ten acres of the quarry site be exposed from
    excavation and not reclaimed.
    204.    To secure funding for the completion of its planned reclamation work, Rivers has
    committed to establishing a reserve account, to be administered by the District Commission, and
    into which Rivers will periodically deposit five cents for every yard of processed rock sold from
    its quarry. These funds will be made available, if necessary, to complete the reclamation work
    -60-
    after Rivers quarry extraction operations are completed.         In any event, Rivers would be
    financially responsible for all planned reclamation work.
    205.   As noted above in Paragraph 21, when all blasting is completed on a specific quarry wall,
    walls will be composed of a series of benches. Each bench will be about fifteen feet in height
    and width/depth. The highest benched wall will be on the northwestern face of the quarry, where
    the area rises most steeply. This area will include about fourteen benches and rise about 210 feet
    from the quarry floor.
    206.   Rivers will use the stored overburden and topsoil to cover the quarry floor and some of
    the quarry wall benches. The area will then be seeded or allowed to naturally vegetate. The
    result will be a flat area, surrounding by three steep, benched quarry walls of varying heights and
    lengths. The easterly side of the quarry, near where the detention pond will be, will remain open
    to the access road.
    207.   This reclamation plan cannot be classified as unique; it follows a pattern often used for
    reclamation in many quarries.       A number of quarries plan for successive uses, including
    residential development and community or recreational uses. While Rivers suggests that its site
    may be used after reclamation for a community use, no specific use has been suggested.
    Legal Conclusions as to Quarry Impacts Upon the Environment and Surrounding Land
    Uses (Act 250 criteria 9(E) and Zoning Regulations §§ 3.5 and 4.10).
    a.      Act 250 Criterion 9(E).
    Act criterion 9(E) provides specific protections from the “unduly harmful impact upon
    the environment or surrounding land uses and development” of earth resource extraction
    projects. 10 V.S.A. § 6086(a)(9)(E)(i). This criterion further restricts the allowable extraction
    projects to those that show “a site rehabilitation plan which insures that upon completion . . . [the
    site] will be left by the applicant in a condition suited for an approved alternative use or
    development.” 10 V.S.A. § 6086(a)(9)(E)(ii). For the reasons stated below, we conclude that
    the Rivers quarry will impose an unduly harmful impact upon area land uses and development.
    As we have previously noted, the area around the Rivers quarry site enjoys many scenic
    characteristics and designations.    Its residents and visitors use the area to enjoy its scenic
    attributes, including the Mad River and the swimming, fishing, and floating opportunities it
    offers; the scenic corridor of Route 100B; the historic residential and agricultural uses in the
    vicinity of the Rivers parcel, and the scenic hillsides beyond the immediate area.
    -61-
    To this area, the Rivers quarry will bring activities and noises not yet experienced; they
    will be new intrusions into this neighborhood and District. While the prospect of fly rock
    trespassing upon neighboring properties will be rare, if occurring at all, Rivers could not provide
    assurances that fly rock will not descend upon neighboring properties and perhaps onto Route
    100B.        While Rivers’ expert credibly asserts that this is unlikely to happen, he also
    recommended that those within 1,500 feet of the quarry site remain indoors during blast events.
    Thus, at least as frequently as a dozen times each operational season, the lives of neighboring
    property owners will be interrupted and they will be directed to remain indoors, lest they wish to
    risk limb, life, or property damage. Both the frequency of these intrusions into neighbors’ lives
    and the disparity between such interruptions and the character of this area, leads us to conclude
    that the project will cause the unduly harmful impacts from which criterion 9(E)(i) seeks to
    protect.
    Rivers correctly notes that the “unduly harmful impact” standard employed in criterion
    9(E) “has been interpreted to include and go beyond aesthetic impacts” of criterion 8, but that
    assessment has not been interpreted as a directive to disregard the project’s conformance with
    criterion 8; in fact, the analysis under these criteria has been interpreted as overlapping and
    related. See Re: John and Marion Gross, d/b/a John Gross Sand and Gravel, No. 5W1198-EB,
    Findings of Fact, Conclusions of Law and Order at 12 15 (Vt. Envtl. Bd. April 27, 1995) (relying
    upon the findings and conclusion under criterion 8 to buttress and provide foundation for initial
    findings and conclusions under criterion 9(E)(i)). In fact, the Board in Goss Sand and Gravel
    gave great weight to facts and legal conclusions particularly applicable to a review of the Rivers
    quarry:
    The Adjoiners’ residential use of their tracts pre-dates, in some cases by decades,
    the inception of the crusher plant operation. To borrow from the language of
    nuisance law, they did not come to the nuisance; the nuisance came to them.
    Accordingly, the Board gives great weight under Criterion 9(E) to the Adjoiners’
    use and enjoyment of their land.
    Id. at 12.

    The Court has relied upon the web-based research tool known as “Casemaker,” offered through the Vermont Bar
    Association. The copy of the Goss Sand & Gravel Decision provided through Casemaker, as well as the copy
    provided through the web page maintained by the Land Use Panel of the Vermont Natural Resources Board, does
    not provide the pagination of the original Decision. The copy retrieved by the Court contains 14 pages; the original
    undoubtedly contains more pages, since Rivers’ citation is to page 16. The Court regrets the confusion its resources
    may cause the parties.

    The Rivers quarry perhaps presents more undue harmful impacts than the quarry
    expansion proposed in Goss Sand and Gravel. Rivers is recommending that neighbors within
    1,500 feet of the quarry suspend their use and enjoyment of their outdoor property whenever a
    blast is to occur. A dozen times per year, for the next thirty-three years. All of Rivers’
    neighbors presently enjoy the scenic natural beauty of their property without interruption; some
    have done so for decades prior to the Rivers quarry being proposed for their neighborhood. The
    Rivers quarry will bring undue harmful impacts to its neighbors; it fails to conform to criterion
    9(E)(i).
    Interference with neighbors beyond this 1,500 foot recommended zone is less severe; to
    the extent that they are free from fly-rock hazards, even if rare, and the adverse impacts of new
    noises, we conclude that the impact by the Rivers quarry upon these outlying neighbors does not
    rise to the level of undue harmful impact under criterion 9(E)(i), even in light of our previously
    stated conclusion of non-conformance to criterion 8. The impact may be adverse, although less
    adverse than that imposed upon Rivers’ more immediate neighbors. We conclude that the
    showing as to the impact upon these other neighbors, including the horse farm owners and
    operators, may be adverse, but does not go beyond that level to reach the heightened standard
    under criterion 9(E)(i) of undue harmful impacts.
    Neighbors Arthur and Linda Hendrickson assert that the Rivers quarry, or rather the
    “prospect of” the quarry, has already had an unduly harmful impact by virtue of a negative
    influence upon the assessed fair market value of their home. They offer evidence of this impact
    through Exhibit N-27: a decision from the Division of Property Valuation and Review of the
    Vermont Department of Taxes regarding the Hendricksons’ appeal of the assessed value of their
    real property, in which a determination was made that the estimated fair market value 16 of the
    Hendricksons’ property declined in value from $129,300 to $116,700. This decline in value is
    explained in general terms by an undefined “public perception” of the prospect that Rivers may
    16
    “Estimated” is perhaps worthy of the greatest emphasis in this phrase. Estimated fair market value sometimes
    has little correlation with the actual sales price of a property in the future. Appraisers attempt to find comparable
    properties that have actually sold and then adjust that reported sales price based upon an estimated value of the
    differences between the sold home and the subject home. Exhibit N-27 includes an explanation that the
    Hendricksons’ home may have decreased in value by as much as 10% due to the “public perception” of the quarry
    Rivers proposes for possible future construction and operation. No further explanation is provided for the
    assessment of a 10% downward impact upon value.
    -63-
    construct and operate a quarry on its adjoining property. For the reasons detailed below, we
    decline to rely upon this evidence for purposes of criterion 9(E)(i) review.
    Neighbors concede that their offer of Exhibit N-27, and reliance upon it for purposes of
    criterion 9(E)(i) review, is not premised upon precedent from any court or former Environmental
    Board decision. Our own research verifies this point; we have found no precedent supporting
    their assertions. However, to say that the issue before this Court is one of first impression is not
    fully accurate. As a former chair of the District 2 Environmental Commission, the undersigned
    recalls more than a few attempts being made by project opponents to introduce speculative
    evidence of possible impacts upon their property values, should a project be approved. Our
    research reveals no precedent of such evidence being admitted or relied upon in an Act 250
    proceeding or appeal.
    Criterion 9(E)(i) presents a heightened threshold: only projects whose impact upon the
    environment or surrounding land uses rises to the level of “unduly harmful” are to be denied an
    Act 250 permit. We have received no foundation for how a speculative estimate of impact upon
    the value of an adjoining property can satisfy the standard of “unduly harmful.”
    To allow such speculative evidence in a state land use permit proceeding opens these
    proceedings to being unduly extended as possible impacts upon property values are argued. We
    saw a small example of such in these proceedings. To establish the precedent that Neighbors
    suggest would open future Act 250 appeals to evidence and arguments that may not even be
    tangentially related to the legal issues properly raised under criterion 9(E)(i).
    Rule 403 of the Vermont Rules of Evidence cautions against the admission of evidence
    whose “probative value is substantially outweighed by the danger of unfair prejudice, confusion
    of the issues” or that may be misleading to the factfinder. Neighbors’ Exhibit N-27 is guilty of
    such dangers. V.R.E. 403. This determination in a tax assessment appeal presents a valuation
    that appears speculative at best; it is founded upon “public perception” of the Rivers quarry; we
    have no foundation that such “perception” is accurate or even casually related to the project
    Rivers actually proposes here.
    Since we deferred our decision on the admissibility of Exhibit N-27 until after the parties
    had filed their post-trial arguments, we announce now that Exhibit N-27 is not admissible for the
    purpose proposed; we decline to rely upon it in our review of criterion 9(E)(i).
    -64-
    Subsection (E)(ii) of criterion 9 requires us to assess the sufficiency of Rivers’ site
    rehabilitation plan; it requires a showing that reclamation will leave the site “in a condition
    suited for an approved alternative use or development.” 10 V.S.A. § 6086(a)(9)(E)(ii). The
    opposing parties here assert that Rivers must be held to an even higher standard; they assert that
    Rivers be required to return the quarry site to its original contours and appearance. We find no
    support for such a standard; we surmise that if criterion 9(E)(ii) were interpreted to require a
    virtual, or even actual, restoration of a site to its original conditions prior to development, no
    quarry could secure Act 250 approval in the entire State of Vermont.
    As stated in our Findings, Rivers’ reclamation plan is far from original or unique. It
    provides for remedial work once all valuable stone has been extracted. The rock walls and faces
    will remain visible, although we do not find that to be adverse or offensive to the preexisting
    uses in the area. One is hard-pressed to live a day in Vermont without observing rock walls and
    faces, including man-made faces. The opposing parties take issue with Rivers’ plan to cover and
    stabilize the quarry floor and benches, at least those that can be safely reached. But their
    opposition appears to be premised more upon aesthetic issues than actual stabilization of the site.
    While criterion 9(E)(ii) provides no direct guidance on this point, we regard its directive that the
    site be “suited for an approved alternative use or development” to mean just that: that the
    reclamation plan must show that the site will be stable and unlikely to suffer material erosion or
    other disturbances once quarry activities are completed and reclamation is accomplished. We
    conclude that Rivers plan does just that.
    b.      Zoning Regulations §§ 3.5 and 4.10.
    Any proposal to commercially extract earth resources, including the drilling, blasting and
    excavation of rock, must be found to “not cause a hazard to public health or safety, or otherwise
    have an undue adverse effect on: (1) neighboring properties and uses.” Zoning Regulations
    §§ 3.5(C), (C)(1). Since this regulatory language is stated in the alternative “or,” we focus upon
    the provision for which we have already found non-conformity: neighbors will be asked to
    suspend their use and enjoyment of their property during each of the dozen blasts, for each of the
    consecutive thirty-three years of operation. We conclude that this constitutes an undue adverse
    impact upon neighboring properties and uses. The quarry operation as proposed is in conflict
    with § 3.5(C)(1). For similar reasons, we conclude that the Rivers project is in conflict with the
    performance standards contained in Regulations §§ 4.10(A), 4.10 (B)(3), and 4.10(B)(4).
    -65-
    Rivers proposals to commence reclamation of portions of its site, even while excavation
    in other phases continues, together with its pledge to maintain and regularly fund a reserve
    account, controlled by the District Commission, provides sufficient surety for the completion of
    its reclamation plan. We therefore conclude that Rivers has satisfied the surety requirements that
    may be imposed under Regulations § 3.5(E).
    VIII. Impact Upon Public Investments.
    208.   Roads, rivers, and other resources that are maintained by public funds constitute public
    investments. The Mad River and Route 100B and its scenic corridor constitute such public
    investments that are located within the vicinity of the Rivers quarry.
    209.   The importance of the Mad River as a public investment is reinforced by the public uses
    and activities upon it: fishing, swimming, the stocking of fish in it by the Department of Fish and
    Wildlife, and the general use and enjoyment of the River are just some examples of the benefits
    flowing from this public resource.
    210.   Route 100B and the scenic enjoyment it provides to its residents and visitors are some
    examples of the benefits of the highway and scenic corridor as a public resource.
    211.   Rivers presented little evidence as to the impacts upon the public investments, other than
    Route 100B.
    Legal Conclusions as to Quarry Impacts Upon Public Investments (Act 250 criteria 9(K))
    Criterion 9(K) directs that when a proposed development is on lands “adjacent to
    governmental and public utility facilities,” or other such facilities in which the public has an
    investment, the development must be shown to “not unnecessarily or unreasonably endanger the
    public or quasi-public investment in the facility, . . . or materially jeopardize or interfere with the
    function, efficiency, or safety of, or the public’s use or enjoyment of or access to the facility,
    service, or lands.” 10 V.S.A. § 6086(a)(9)(K). The parties’ discussion of this topic direct us to
    an initial issue: what is an “adjacent” public investment?
    Much of the prior precedent cited by the parties has little discussion of this term. See Re:
    Pittsford Enters., LLP, No. 1R0877-EB, Findings of Fact, Conclusions of Law and Order at 36
    (Vt. Envtl. Bd. Dec. 31, 2002) (citing multiple cases). We therefore turn to lay dictionaries for
    guidance; both the Webster’s II College Dictionary (2005) and the website Dictionary.com
    define “adjacent” as being “near to” and “close”; the latter resource provides the additional
    -66-
    definitions of “contiguous; adjoining.” Given the breadth of these definitions, we conclude that
    both Route 100B and the Mad River (although it is over 1,000 feet away) constitute adjacent
    public investments, but that the other facilities suggested by the opposing parties, including
    public facilities in the Village, are beyond the reach of “adjacent” public investment, as the term
    is used in criterion 9(K).
    When considering the impact upon a state or local highway, as a public investment,
    review can be very similar under criteria 5 and 9(K). Pittsford Enters., No. 1R0877-EB at 36.
    Further, criterion 9(K) provides for a lower threshold, since its focus is upon whether the
    proposed project will “materially jeopardize or interfere with the function, efficiency, or safety
    of, or the public’s use or enjoyment of or access to the facility, service, or lands.” 10 V.S.A.
    § 6086(a)(9)(K). We regard this standard as lower than the standard of criterion 5 (“will not
    cause unreasonable congestion or unsafe conditions”), as did the former Environmental Board in
    Pittsford.   Id. (quoting Re: John A. Russell Corp., No. 1R0849-EB, Findings of Fact,
    Conclusions of Law, and Order at 9 (Vt. Envtl. Bd. July 10, 2001)).
    We have already discussed extensively the impacts the quarry will likely have on Route
    100B and those who use that public resource. For reasons similar to those expressed in our
    analysis under criterion 5, we conclude that, while the quarry will have an impact upon Route
    100B and its travelers, its impact will not be so significant as to materially jeopardize or interfere
    with the function, efficiency, or safety of, or the public’s use or enjoyment of or access to Route
    100B. We therefore conclude that the Rivers quarry conforms to criterion 9(K).
    In regards to the quarry’s impact upon the Mad River, and the public’s use and enjoyment
    of this public resource, we find even less basis for conflict with criterion 9(K). There was no
    credible evidence to support a determination that the quarry operations will materially jeopardize
    or interfere with the function of the River or the public’s access to it. Noises and other quarry
    impacts will be more distant than for those on Route 100B or the quarry’s most immediate
    neighbors. There is no conflict presented by the quarry with the interests protected by Act 250
    criterion 9(K).
    IX. Conformance with Town Plan.
    212.    Extraction of earth resources within the Ag-Res District may be authorized, if granted
    conditional use approval under the Zoning Regulations. Regulations Table 2.3(3)(8).
    -67-
    213.    As previously stated, due to the dates on which Rivers filed complete applications, the
    Town Plan applicable to these proceedings is that which was adopted on August 27, 2002.
    Subsequently adopted versions of the Moretown Town Plan are not applicable to these
    proceedings.
    214.    The Town Plan is organized in the following Chapters:
    1)   Planning Process;
    2)   Population;
    3)   Housing;
    4)   Natural and Cultural Resources;
    5)   Transportation;
    6)   Facilities and Services;
    7)   Land Use; and
    8)   Plan Implementation.
    215.    Each Chapter of the Town Plan closes with a section entitled “Goals, Policies, Tasks and
    Strategies.” Each subsection to each Chapter of the Town Plan is indexed; the Plan provides a
    clear directive of the Town’s desires, directives, goals, policies, tasks, and strategies.
    216.    Chapter 4 contains a subsection titled “Soils and Earth Resources.” Town Plan at 22–23.
    Within this subsection, a portion entitled “Gravel Resources” states as follows:
    No commercial mineral deposits have been located in Moretown, although several
    concentrations of sand and gravel have been excavated over the years. Because of
    the importance of sand and gravel to the community for road maintenance and
    construction, some future extraction of these resources should be anticipated.
    However, the environmental and social impacts of large scale extraction need to
    be considered prior to development. Such impacts can be avoided or mitigated
    through careful site planning, operation and reclamation. Demonstrating, during
    the permitting process, that adverse impacts on neighbors and the Town will be
    minimized and adequate provision for site reclamation made, are an important
    means of avoiding problems.
    Id. at 23.
    217.    Chapter 4 of the Town Plan, under the heading “Steep Slopes,” notes that “[l]arge areas
    of steeply sloping hillsides are a significant feature of Moretown’s varied terrain. Such areas
    pose several land use and development challenges, including susceptibility to erosion and high
    rates of run-off, particularly when cleared for construction, agriculture or forestry.” Id. at 24.
    218.    This subsection of Chapter 4 goes on to note:
    [g]enerally, slopes in excess of 25% should not be developed and clearing for
    agriculture and forestry should be conducted with careful attention to erosion
    -68-
    control and stormwater management measures. Most development should also be
    avoided on slopes of 15–25%, although limited development may take place
    providing measures are taken to ensure slope stabilization, erosion control and
    down-slope protection from stormwater runoff.
    Id.
    219.   In Chapter 7, entitled “Land Use,” the Town Plan provides several “Land Use Policies,”
    one of which states: “Development on slopes in excess of 25% shall be prohibited.” Id. at 68.
    220.   The Rivers quarry occurs on lands that currently vary in slope. A portion of the quarry
    site currently encompasses a plateau area. The slope of the access road to the project site also
    varies, but some limited areas are in excess of 15%. No large area to be disturbed by the quarry
    operation is in excess of 25%. We use the term “large area” with reference to that specific term
    being used in the introduction to the “Steep Slopes” subsection within Chapter 4. Id. at 24.
    221.   Chapter 4 also includes a subsection titled “Open Space/Scenic Resources.” Id. at 30–31.
    This subsection provides the following description for the Route 100B/Mad River Corridor:
    Route 100B/Mad River Corridor: The drive along the length of Route 100B is
    among the most beautiful in Vermont. The meandering river, broad flood plains,
    rolling hills and deep gorges combine to create a stunning landscape. The
    Planning Commission studied this route in 1999–2000 and concluded that most of
    its defining features are located within a broad corridor defined by a distance of
    300 feet east and west of the 100 year floodplain.
    222.   Under the heading: “Natural and Cultural Resources & Strategies,” Chapter 4 contains
    the following directive: “The Development Review Board shall, through the conditional use
    review process, ensure that the extraction of gravel and other mineral resources do not
    permanently scar the landscape, adversely impact ground or surface waters, or unreasonably
    impact adjacent neighbors.” Id. at 35.
    223.   Chapter 7 includes under the subsection “Planning Considerations” the directive that
    “two areas of special concern regarding the impact of new development on the town’s natural
    and scenic resources are upland areas and the Route 100B/Mad River Corridor.” Id. at 68.
    Legal Conclusions as to Conformance to Town Plan (Act 250 criterion 10).
    Act 250 requires that a proposed project conform to a duly adopted Town Plan. 10
    V.S.A. § 6086(a)(10). This criterion also requires a showing that the project conforms to a duly
    adopted regional plan and capital improvement program. We do not address conformance with a
    regional plan, since that issue was not preserved for our review by any appellant in these
    -69-
    proceedings. We have not been made aware that a capital improvement program has been duly
    adopted, or preserved for our review in this appeal.
    Any review of this criterion can be daunting, since most town or regional plans are more
    easily measured in inches than in pages. The Moretown Town Plan is no different, although it is
    well organized and indexed. Our review of this criterion has also been made more succinct,
    since the parties exhaustively researched and presented the issues related to Town Plan
    conformance in a number of pretrial motions. Those motions and the issues the parties raised are
    most directly addressed in two Corrected Interim Decisions, both filed on January 18, 2008. See
    Corrected Decision on Rivers’ Initial Motions (filed Jan. 18, 2008) and Corrected Decision on
    Neighbors’ Motion for Summary Judgment (filed Jan. 18, 2009). We refer the reader to those
    decisions for our legal determinations as to permissive and regulatory language in the Town
    Plan, and the role of Zoning Regulations in deciphering an ambiguous Town Plan provision.
    That reference allows us to avoid repeating that analysis in this Decision.
    Much discussion was had, both before and during trial, as to whether the Rivers quarry
    conflicts with the steep slopes provisions in the Town Plan. Our analysis is made more difficult
    here because the Plan contains conflicting provisions. Compare the references in our Findings to
    Chapters 4 and 7, above. However, we conclude that the Rivers quarry does not conflict with the
    applicable Town Plan provisions regarding steep slopes, since the Chapter 4 provisions help
    clarify that it is “large areas” of steep slopes that the Plan provisions express concern about, not
    the undulating topography that is evident on the Rivers site.
    There is no dispute that the Rivers site rises in elevation from its access on Route 100B.
    Other than the plateau area, near where the detention pond will be situated, there are few
    examples of level ground on the site. But the terrain is undulating, especially where rock
    exposes itself from the ground.        We received no evidence that the land rises steeply and
    consistently in large areas. Our two site visits helped provide context to this and other evidence.
    Further, Rivers has provided sufficient planning and secured coverage under the MSGP,
    so as to receive positive findings in this proceeding as to stormwater and soil erosion. These are
    the very concerns which the “Steep Slopes” subsection of Chapter 4 lists as concerns. We are
    unconvinced that a quarry such as the one Rivers proposes here is the type of “development” on
    large areas of steep slopes that the Plan sought to protect against. We find no conflict in the
    Rivers quarry with these provisions.
    -70-
    More troubling are the conflicts the Rivers quarry presents in regards to the Plan
    provisions concerning the importance of the scenic features of the area, and the need for earth
    extraction projects to respect those scenic resources and the safe use and enjoyment of
    neighboring properties. Our analysis is more detailed on these topics in connection with similar
    provisions in Zoning Regulations §§ 3.5, 4.10, and 5.2. For those same reasons, we conclude
    that the Rivers quarry, as proposed, is in conflict with the scenic features of the Route 100B/Mad
    River corridor and the use and enjoyment of neighboring properties. Since both provisions are
    given specific expression in the Town Plan, we conclude that the quarry is in conflict with the
    Plan.
    Conclusion
    For all the reasons stated in more detail above, we conclude that the quarry proposed by
    Rivers Development, LLC is in conflict with Act 250 criterion 8, 9(E), and 10, as well as the
    applicable provisions contained in the Moretown Zoning Regulations §§ 3.5, 4.10, and 5.2. Due
    to these nonconformities, we hereby DENY Rivers’ pending applications for an Act 250 state
    land use permit and a municipal conditional use permit.
    This concludes the current proceedings before this Court.            A Judgment Order
    accompanies this Decision.
    Done at Newfane, Vermont, this 25th day of March, 2010.
