    OPINION OF THE COURT
    ROTH, Circuit Judge:
    The Enola Branch is a 66.5 mile railroad line which was
    built in the early Twentieth Century and was known as one
    of the remarkable engineering feats of that time. Petitioner,
    Friends of the Atglen-Susquehana Trail, Inc. (FAST), seeks
    judicial review of a final order of the Surface Transportation
    Board (STB)1 permitting abandonment of the Enola Branch.
    _________________________________________________________________
    1. The STB is the federal agency having exclusive jurisdiction over
    transportation by railroad. See 49 U.S.C. S 10501(a)(1). The STB is the
    successor agency to the Interstate Commerce Commission (ICC), which
    was abolished by Congress in 1995. See ICC Termination Act of 1995,
    S 101, P.L. 104-88, 109 Stat. 804, 49 U.S.C. S 701 note (1995). That act
    also established the STB, see 49 U.S.C.S 701, and provided that it
    would perform all the functions that pr eviously were performed by the
    ICC as of the effective date of the act. See 49 U.S.C. S 702; see also ICC
    Termination Act of 1995, S 204, P .L. 104-88, 109 Stat. 804, 49 U.S.C.
    S 701 note.
    In this opinion, we will refer to the agency as the ICC before its
    abolition and as the STB afterwards.
    2
    FAST challenges the manner in which the STB carried out
    its responsibilities under S 106 of the National Historic
    Preservation Act (NHPA), 16 U.S.C. S 470f. In particular,
    FAST objects to the manner in which the STB identified and
    protected historic properties along the line, to the STB's
    failure to consider evidence that the corridor as a whole
    was entitled to protection as a historic pr operty, and to the
    manner in which the STB terminated consultation on a
    plan to protect historically eligible pr operty. For the reasons
    that follow, we will vacate the STB's decision and r emand
    this matter to it for further consideration.
    I. REGULATORY BACKGROUND
    A. ABANDONMENT OF RAIL LINES
    FAST seeks review of the actions of the STB in the
    exercise of its exclusive regulatory jurisdiction over rail
    carriers and rail transportation, particularly its jurisdiction
    to permit a rail carrier to abandon or discontinue use of an
    existing rail line that might qualify as or contain historic
    property. We begin, therefor e, with an overview of the
    relevant regulatory landscape.
    A rail carrier intending to abandon, and to be r eleased
    from its obligations to retain or operate, any part of its
    railroad lines must file an application to do so with the STB
    and such abandonment must adhere to certain established
    procedures. See 49 U.S.C. S 10903(a)(1)(A); see also 49
    U.S.C. SS 10903-10907. The STB is empower ed to exempt a
    transaction from the ordinary regulatory requirements if
    the STB finds that the ordinary procedur es are not
    necessary to carry out federal transportation policy and
    that either the transaction is limited in scope or the full
    application procedures are not necessary to protect
    shippers from any abuses of market power . See 49 U.S.C.
    S 10502(a).
    The abandonment of a rail line or corridor will qualify as
    an exempt transaction if the carrier certifies that no local
    traffic has moved over the line for at least two years, that
    any traffic on the line can be rerouted over other lines, and
    that no formal complaints, regarding cessation of service on
    3
    the line, are pending or have been decided within that two-
    year period. See 49 C.F.R. S 1152.50(b). This process is
    intended to be an expedited one. The exemption, and
    therefore permission to abandon the rail line, becomes
    effective 30 days after publication of notice in the Federal
    Register. See 49 C.F.R. 1152.50(d)(3); see also 49 U.S.C.
    S 10502(b) ("Any proceeding begun as a result of an
    application under this subsection shall be completed within
    9 months after it is begun."). An exempt abandonment
    remains subject to any conditions that the STB may impose
    upon it.
    If the STB agrees that a proposed abandonment is
    exempt and allows the abandonment to proceed under the
    expedited procedures, the STB must consider certain
    factors prior to permitting the abandonment to become
    final. See 49 C.F.R. S 1152.50(a)(2). First, the STB must
    consider and determine whether the rail pr operties to be
    abandoned are appropriate for use for public purposes. See
    49 U.S.C. S 10905;2 49 C.F .R. S 1152.28(a)(1). If the STB
    finds that the properties are appr opriate for public use, the
    STB is authorized to impose conditions on the
    abandonment of the property by the carrier . Such
    conditions may include a prohibition on the disposal of the
    property for a period of 180 days unless the pr operty is first
    offered, on reasonable terms, for sale for public purposes.
    See 49 U.S.C. S 10905; 49 C.F.R. S 1152.28(d). Second, the
    STB must consider possible interim trail use or rail banking,3
    should any state, political subdivision, or qualified private
    organization be interested in acquiring or using the rail line
    right-of-way in such a manner. See 16 U.S.C. S 1247(d); 49
    C.F.R. S 1152.29. Third, the STB must comply with the
    requirements of S 106 of the National Historic Preservation
    Act, 16 U.S.C. S 470f.
    The exemption procedures of S 10502 and S 1152.50 are
    intended to expedite the approval of the pr oposed
    abandonment by making it effective almost immediately,
    _________________________________________________________________
    2. Formerly 49 U.S.C. S 10906.
    3. This would permit the railroad right-of-way to be used in some interim
    manner and to be preserved for future r estoration or reconstruction and
    reactivation for railroad purposes. See 49 U.S.C. S 1247(d).
    4
    subject to any conditions imposed by the STB.
    Consideration of the S 106 historic pr eservation process, on
    the other hand, necessarily requires the STB to proceed
    more slowly. The fact that Congress has introduced a
    procedure which permits the slowing of the overall
    abandonment process reflects Congr ess's intent to balance
    immediate, fast-track approval of the abandonment by the
    carrier with a more deliberate consideration of preservation
    of historically significant properties. See Concerned Citizens
    Alliance, Inc. v. Slater, 
    176 F.3d 686
    , 695-96 (3d Cir. 1999)
    (citing Illinois Commerce Comm'n v. ICC , 
    848 F.2d 1246
    ,
    1260-61 (D.C. Cir. 1988) (describing S 106 as "stop, look,
    and listen" provision requiring an agency to acquire
    information before acting)).
    B. HISTORIC PRESERVATION
    Section 106 of the NHPA provides as follows:
    The head of any Federal agency having dir ect or
    indirect jurisdiction over a proposed Federal or
    federally assisted undertaking in any State and the
    head of any Federal department or independent agency
    having authority to license any undertaking shall, prior
    to the approval of the expenditure of any Federal funds
    on the undertaking or prior to the issuance of any
    license, as the case may be, take into account the
    effect of the undertaking on any district, site, building,
    structure, or object that is included in or eligible for
    inclusion in the National Register.
    16 U.S.C. S 470f. The NHPA is a pr ocedural statute
    designed to ensure that, as part of the planning process for
    properties under the jurisdiction of a federal agency, the
    agency takes into account any adverse effects on historical
    places from actions concerning that pr operty. See Morris
    County Trust for Historical Preservation v. Pierce, 
    714 F.2d 271
    , 278-79 (3d Cir. 1983). The STB, as a federal agency,
    must adhere to S 106 in considering and approving
    exemption or abandonment of a rail line. See 36 C.F.R.
    S 800.2(a).
    The Advisory Council on Historic Preservation (ACHP) has
    promulgated regulations outlining the pr ocedures to be
    5
    followed by an agency in satisfying its responsibilities under
    S 106, codified at 36 C.F.R. Part 800. See Morris County
    
    Trust, 714 F.2d at 280
    ("[T]he Advisory Council's
    regulations are particularly persuasive concerning the
    proper interpretation of NHPA.") An agency is expected to
    consult with various interested parties thr oughout the
    S 106 process, including the State Historical Preservation
    Officer (SHPO), who is the state official appointed or
    designated, pursuant to S 101(b)(1) of the NHP A, 16 U.S.C.
    S 470a(b)(1), to administer the state historic preservation
    program. See 36 C.F.R. S 800.16(v); see also 16 U.S.C.
    S 470a(b)(3) (establishing the responsibilities of the SHPO).
    The agency, in consultation with the SHPO, must also
    involve the public in the process, see 36 C.F.R. S 800.3(e),
    and identify other parties that should be invited to
    participate in the process as consulting parties, including
    local governments and those parties that r equest to
    participate in the process. See 36 C.F .R. S 800.3(f)(1-3). The
    ACHP itself must be afforded a "r easonable opportunity to
    comment on such undertakings." 16 U.S.C. S 470f; 36
    C.F.R. S 800.1(a); see also Concer ned 
    Citizens, 176 F.3d at 695
    (holding that the Council's comments must be taken
    into account and integrated into the decisionmaking
    process).
    The ACHP regulations establish a three-step process:
    identification of historic properties; assessment of any
    adverse effects of the proposed undertaking on such
    properties; and creation of a plan to avoid, minimize, or
    mitigate those adverse effects. See 36 C.F.R. S 800.1(a). The
    agency, in consultation with the SHPO and other interested
    parties, may address multiple steps in one consultation as
    long as all parties are given an adequate opportunity to
    comment. See 36 C.F.R. S 800.3(g).
    In order to identify historic properties, the agency must
    apply the criteria established for the National Register of
    Historic Places (National Register) to identify pr operties and
    to determine whether they would be eligible for the National
    Register. See 36 C.F.R. S 800.4(c)(1). Significantly, the
    regulations provide that the "passage of time, changing
    perceptions of significance, or incomplete prior evaluations
    may require the Agency Official to r eevaluate properties
    6
    previously determined eligible or ineligible." 36 C.F.R.
    S 800.4(c)(1).
    If the agency and the SHPO agree that the criteria for the
    National Register have been met, the property or portion
    thereof shall be considered eligible for the National Register
    for S 106 purposes. See 36 C.F .R. S 800.4(c)(2). If the
    agency and the SHPO agree that the criteria have not been
    met, the property is considered ineligible. See 
    id. If the
    agency and the SHPO do not agree, or if the ACHP or the
    Secretary of the Interior so requests, the agency "shall"
    obtain a determination from the Secr etary, acting through
    the Keeper of the National Register (Keeper), as to the
    historic eligibility of the property. See 
    id. Other courts
    of
    appeals have held that this determination by the Secretary
    or the Keeper should be conclusive. See Moody Hill Farms
    Ltd. Partnership v. United States Department of the Interior,
    
    205 F.3d 554
    , 558 (2d Cir. 1999) (describing the
    independent authority of the Keeper, on behalf of the
    Secretary, to determine whether a pr operty should be listed
    as historic); Stop H-3 Ass'n v. Coleman, 
    533 F.2d 434
    , 441
    n.13 (9th Cir.) (noting that the Secr etary's opinion as to the
    historic eligibility of property is conclusive).
    If the agency finds that there are no historic properties
    that will be affected by the undertaking, the agency must
    document its findings and provide such documentation to
    the ACHP, the SHPO, and other consulting parties. The
    SHPO and the ACHP have 30 days to object to thatfinding;
    otherwise, the agency's S 106 responsibilities are deemed
    completed. See 36 C.F.R. S 800.4(d)(1). If the agency finds
    that there are historic properties that may be affected, the
    agency must notify all consulting parties and invite their
    views on the effects of the proposed undertaking and their
    assessments of any adverse effects. See 36 C.F.R.
    S 800.4(d)(2).
    An adverse effect is found when the undertaking may
    alter, directly or indirectly, any of the characteristics that
    make a property historic and eligible for inclusion in the
    National Register. See 36 C.F .R. SS 800.5(a)(1), 800.16(i).
    Such adverse effects include physical destruction of or
    damage to all or part of the property, alteration of the
    property, removal of property fr om its historic location, or
    7
    a change in the character of the property's use. See 36
    C.F.R. S 800.5(a)(2). The regulations establish the steps that
    an agency must take in determining whether or not there
    are adverse effects and in notifying interested parties of its
    findings. See 36 C.F.R. S 800.5. However, agencies, as did
    the STB here, will often assume the occurr ence of adverse
    effects to properties identified as historic. Once the agency
    finds (or assumes) the existence of adverse ef fects, the
    agency must continue consulting with the parties in order
    to resolve such adverse effects and to develop and evaluate
    alternatives or modifications to the undertaking that will
    avoid, minimize, or mitigate such effects. See 36 C.F.R.
    SS 800.5(d)(2), 800.6(a). The agency must also notify the
    ACHP of the adverse effect finding and pr ovide certain
    specified documentation. See 36 C.F .R. S 800.6(a)(1).
    The process then moves to the third andfinal step, the
    resolution of adverse effects and the development of a plan
    to avoid, minimize, or mitigate the adverse ef fects. At this
    stage, the SHPO and any other consulting parties may
    invite the ACHP to participate in the consultation; under
    certain circumstances, the ACHP must be invited to
    participate. See 36 C.F.R. SS 800.6(a)(1)(i), (ii). The agency
    and the other consulting parties may also agr ee to invite
    new parties to consult. They are requir ed to invite any
    organization that will play a specific r ole or assume special
    responsibility in any mitigation plan. See 36 C.F.R.
    S 800.6(a)(2).
    The ACHP has discretion at this stage to decide if it will
    consult formally. See 36 C.F.R.S 800.6(a)(1)(iii); see also 36
    C.F.R. Part 800 App. A (setting forth criteria that the ACHP
    uses to determine whether formally to enter a particular
    S 106 review). Its decision deter mines how the agency must
    proceed. If the ACHP chooses not to join the consultation
    formally, section 800.6(b)(1) of the ACHP r egulations
    controls. The agency consults with the SHPO and other
    consulting parties in devising a plan to avoid or mitigate
    the adverse effects. If the agency and the SHPO agree on a
    plan, they execute a Memorandum of Agreement (MOA), a
    copy of which must be submitted to the ACHP for its
    comments prior to the agency approving the undertaking.
    See 36 C.F.R. S 800.6(b)(1)(iv); see also 36 C.F.R.
    8
    S 800.6(c)(1)(i). An executed MOA evidences the agency's
    compliance with S 106 of the NHPA and governs the
    carrying out of the federal undertaking. See 36 C.F.R.
    S 800.6(c). If the agency and the SHPO fail to agree on a
    plan, the agency must ask the ACHP formally to join the
    consultation. See 36 C.F.R. S 800.6(b)(1)(v). If the ACHP
    again declines to consult formally, it must pr ovide
    comments on the undertaking and on the status of the
    S 106 review, which the agency must consider in reaching
    any final decision as to mitigation. See 36 C.F.R.
    S 800.6(b)(1)(v); see also 36 C.F .R. S 800.7(c).
    If, at any point, the ACHP formally joins the consultation
    on mitigation, section 800.6(b)(2) controls. The ACHP must
    execute the MOA along with the agency, the SHPO, and any
    other consulting parties. See 36 C.F .R. S 800.6(b)(2); see
    also 36 C.F.R. S 800.6(c)(1)(ii). Any party that assumes a
    responsibility in carrying out the MOA may also be asked
    to be a signatory to the MOA. See 36 C.F .R. S 800.6(c)(2)(ii).
    If, at any point during consultation, the agency, the
    SHPO, or the ACHP determines that further consultation
    will not be productive, any of them may, upon notice to the
    other consulting parties, terminate consultation. See 36
    C.F.R. S 800.7(a). If the agency ter minates the consultation,
    it must request and receive comment fr om the ACHP. See
    36 C.F.R. S 800.7(a)(1).
    Comments from the ACHP are governed by S 800.7(c).
    The ACHP has 45 days from receipt of a r equest to provide
    comments on an agency's termination of mitigation
    consultation, pursuant to S 800.7(a)(1), or on an agency's
    statement that it is unable to reach an MOA thr ough
    consultation with the SHPO alone, pursuant to
    S 800.6(b)(1)(v). See 36 C.F.R.S 800.7(c)(2). The agency
    must take these comments into account in reaching a final
    decision on the undertaking, see 36 C.F .R. S 800.7(c)(4),
    and the agency is required to document that it did so by
    explaining its decision and providing evidence that it
    considered the ACHP's comments. See 36 C.F.R.
    S 800.7(c)(4)(i); see also Concerned 
    Citizens, 176 F.3d at 696
    (stating that the "relevant agency must demonstrate that it
    has read and considered" the opinions and
    recommendations of the ACHP). This decision and
    9
    explanation is to be provided to the ACHP , to all consulting
    parties, and to the public prior to the final appr oval and
    carrying out of the undertaking. See 36 C.F .R.
    SS 800.7(c)(4)(i-iii).
    II. FACTS
    There is no dispute as to the underlying facts or the
    course of the regulatory proceedings in this matter. In
    October 1989, Conrail4 filed a Notice of Exemption with the
    ICC, seeking to abandon the Enola Branch, a 66.5-mile rail
    corridor running through Lancaster and Chester Counties,
    in Pennsylvania. Conrail certified that no traffic had moved
    over the line for two years. There is no suggestion that
    Conrail did not adhere to the filing and notice requirements
    for seeking an exemption. Lancaster County objected to
    Conrail's petition, primarily seeking a public use or interim
    trail use and rail banking condition on the exemption.
    Although the County did not expressly raiseS 106 or seek
    a historic condition on the abandonment, it did pr ovide the
    following description of the rail line to the ICC:
    The Enola Branch railroad line itself is a historically
    significant resource. Pennsylvania Railr oad President
    A.J. Cassett built the railroad line as a passenger route
    through Pennsylvania and Ohio in the first decade of
    this century. It was once a vital east-west fr eight line
    for southeastern Pennsylvania. The families of Italian
    laborers constructed the line and now inhabit the
    Quarryville area. The railroad corridor is designed and
    constructed to have little slope, so it either cuts into
    the ground or is elevated over most of its length. The
    project is known as one of the most remarkable
    engineering feats of its time. The physical impacts of
    the corridor on adjacent land owners is negligible. The
    line is very well designed with the landscape to limit
    obtrusiveness to the natural character of the ar ea. It is
    _________________________________________________________________
    4. Conrail's assets have been acquired by, and divided between, two
    railroad operations, Norfolk Souther n Corp. (Norfolk) and CSX Corp. The
    former Enola Line is now controlled by Norfolk, which intervened in this
    appeal on behalf of the STB.
    10
    said the earth moving involved in the project rivaled
    that of the construction of the Panama Canal.
    The ICC issued an Order on February 22, 1990 (1990
    Order) in which it granted to Conrail the exemption, subject
    to three conditions: 1) that Conrail keep intact all the right-
    of-way underlying the track, including bridges and culverts,
    for a period of 180 days, to allow for the negotiation of a
    public use acquisition; 2) that Conrail comply with terms
    and conditions for implementing possible interim trail use
    and rail banking; and 3) "that Conrail take no steps to alter
    the historic integrity of the bridges on the line until
    completion of the section 106 process of the National
    Historic Preservation Act, 16 U.S.C. S 470." Negotiations
    between Conrail and Lancaster County to preserve the line,
    either through sale for public use or for interim trail use
    and rail banking, proved unsuccessful, despite extensions
    well beyond the 180-day period provided for in the 1990
    Order. The record indicates that the trail use plan fell
    through in part because FAST was unable to act as a
    financially responsible party for an interim trail use or to
    find a public sponsor, as requir ed under 49 C.F.R.
    S 1152.29(a)(2). On April 19, 1993, the ICC denied
    Lancaster County's request for a further extension of the
    negotiating period, vacated the trail use condition, and
    granted Conrail permission to abandon the line (1993
    Order).
    The remaining condition on abandonment was for the
    preservation of historically significant pr operties, pending
    STB's completion of the S 106 process. The 1990 Order only
    required preservation of the historic integrity of the bridges
    on the line. This limitation apparently was based on a 1989
    telephone conversation between a member of the ICC's
    Section of Environmental Analysis (SEA) and Pennsylvania's
    SHPO, the Pennsylvania Historical and Museum
    Commission, Bureau for Historic Preservation (PHMC). In
    that conversation, the SHPO indicated that some or all of
    the 83 bridges on the line potentially were eligible for
    inclusion in the National Register but that it had not
    completed its review. The 1990 Order did not discuss or
    address the comments from Lancaster County about the
    historic significance of the line as a whole. The ICC also
    11
    never sought a determination from the Secretary of the
    Interior or the Keeper as to the historic eligibility of the line
    as a whole or of other portions of the rail corridor . The 1990
    Order made no final identification of eligible historic
    properties but limited the scope of possible historic
    properties to some or all of the bridges on the line, as
    initially identified by the SHPO in the telephone
    conversation.
    The ICC then followed its common practice of assuming
    that abandonment of the Enola Branch corridor would
    adversely affect the rail properties identified as historic, i.e.,
    some or all of the 83 bridges. The ICC therefor e proceeded
    to the third step in the S 106 pr ocess, development of a
    plan to avoid, minimize, or mitigate the adverse ef fects. The
    record does not indicate, however, that the ICC notified the
    ACHP of the presumptive finding of adverse ef fects.
    The final, mitigation stage of the S 106 pr ocess was also
    a long one. It was complicated by the fact that in April
    1996, FAST petitioned the STB to reopen the proceedings
    and to broaden the S 106 condition to encompass the entire
    Enola Branch, as the eligible historic property to be
    preserved. In its petition, FAST r elied on a letter dated
    February 24, 1994, from Brenda Barr ett, director of the
    PHMC (the Pennsylvania SHPO), to Wendy T ippetts of an
    organization known as "TWO."5 In that letter, Barrett stated
    that, in the opinion of the SHPO, the Enola Branch and the
    Atglen & Susquehana Branch both were eligible for listing
    in the National Register. The STB was sent a copy of the
    letter.
    The STB responded to the petition on October 2, 1997
    (1997 Order) by ordering that 1) the pr oceeding was
    reopened, 2) the request by FAST to expand the condition
    to include the entire Enola Line was denied, and 3) the
    S 106 condition imposed in 1990 was modified to
    encompass only 32 bridges on the line and ar chaeological
    sites near 36 bridges as the properties eligible for listing in
    _________________________________________________________________

    Tippetts as consultant in the efforts to preserve the corridor as historic
    property. Nothing has been presented to us explaining what "TWO"
    stands for.
    12
    the National Register. In explaining its decision to deny
    FAST's petition to expand the scope of the eligible historic
    property, the Board stated that
    Neither FAST nor the SHPO has provided any
    justification for the SHPO's apparently changed
    position with regard to eligibility of the entire line in
    the National Register. Indeed, the SHPO letter
    submitted by FAST does not even acknowledge that the
    SHPO had ever reached a previous deter mination on
    this matter. . . . It is clear that the SHPO was originally
    concerned only with the eligibility of certain bridges
    and archaeological sites for section 106 purposes. The
    fact that certain items were included in the SHPO's
    original opinion while others were excluded indicates
    that the SHPO did not originally consider the entir e
    line eligible.6
    FAST timely petitioned for reconsideration of the refusal
    to reopen the proceedings and to expand the identified
    eligible historic properties. With that petition pending, the
    parties proceeded along separate tracks. F AST and other
    interested parties requested that the STB formally submit
    the question of the historical significance of the Enola
    Branch line as a whole to the ACHP for referral to the
    Secretary of the Interior and the Keeper for a conclusive
    determination. When FAST received no response from the
    STB, FAST asked the ACHP to become involved in the
    process. The ACHP wrote to the STB in Mar ch 1998,
    asserting that the STB never notified the ACHP of its
    finding of adverse effects, never identified potentially
    interested parties to consult on the S 106 process, and
    never informed the ACHP as to how it identified eligible
    property. The ACHP requested that it be included in the
    S 106 process and that it be provided background
    documentation. The STB never responded to this letter.
    _________________________________________________________________
    6. The STB also questioned the applicability of the letter, noting that,
    although the caption of the letter contained the correct docket number,
    it referred to a project encompassing additional lines and counties. The
    STB stated that it "is unclear what this pr oject entails." The STB also
    noted that any information submitted by F AST in support of the
    eligibility of the entire line had not been supplied to Conrail or
    submitted
    for entry in the public record.
    13
    Meanwhile, the STB proceeded as if the first two steps of
    the S 106 process, identification of eligible properties and
    determination of adverse effects, had been concluded and
    the only remaining step was to devise a plan to mitigate the
    adverse effects on the bridges and archaeological sites that
    it had identified as eligible properties. The STB formally
    consulted with the SHPO and Conrail; the recor d does not
    indicate that the STB formally invited the ACHP to consult
    on the mitigation plan. In August 1998, the STB drafted an
    MOA, memorializing terms that had been agr eed upon by
    the SHPO, Conrail, and the STB. The plan provided that 1)
    Conrail would perform recor dation of five identified bridges
    to State Level Recordation Standards prior to the demolition
    of those bridges, 2) Conrail would provide funding in excess
    of $15,000 to the Railroad Museum of Pennsylvania for
    development of a 6-8 minute video outlining the history of
    the Enola Branch, 3) Conrail would convey segments of the
    abandoned line and bridges to local townships and would
    provide the municipalities with an agreed sum of money for
    future maintenance of those bridges.
    The MOA was submitted to the SHPO and Conrail for
    execution, to the ACHP for approval, as well as to FAST and
    the Historic Preservation Trust of Lancaster County (the
    Trust) for comments. In the transmittal letter to the ACHP,
    the STB for the first time broached the possibility of
    breaking off consultation, stating that"[i]f it appears that
    further consultation would not be productive, we will
    terminate consultation."
    The SHPO declined to sign the MOA, citing the ACHP's
    concerns that it had not been asked to consult in the
    development of the MOA; the SHPO withheld further r eview
    and signature of the plan until the STB had consulted with
    the ACHP. FAST stated specific objections to the draft MOA,
    noting FAST's desire to preserve the line and to establish a
    trail on the corridor. FAST also objected to the manner in
    which public input had been gathered for the pr oject.
    The ACHP, upon receipt of the draft MOA, asserted that
    the matter of the STB's overall compliance withS 106
    "remains unresolved" and that "serious shortcomings
    persist in STB's evaluation of historic properties,
    solicitation of public input, evaluation of alter natives, and,
    14
    development of a mitigation plan." Further , the ACHP
    discussed the provisions in the S 106 r egulations that
    provide for reevaluation of determinations of eligibility and
    for the possible involvement of the Secretary of the Interior.
    The ACHP concluded that "the eligibility issue r egarding the
    historic significance of the entire Enola Branch Line will
    need to be resolved before we can consider the draft MOA."
    The ACHP stated that only after receiving for mal comments
    from the Keeper could the ACHP evaluate whether all
    possible effects had been considered. The ACHP also
    suggested a meeting among the STB, the SHPO, Conrail,
    and the ACHP.
    In its February 1, 1999, response, the STB described the
    manner in which it had carried out the identification
    process and asserted that the identification and effects
    phases of the S 106 process had been completed and need
    not be reopened. The STB specifically noted that changed
    perceptions or evaluations of what is historically significant
    and therefore eligible for the National Register may indeed
    justify reevaluation or reopening of pr oceedings but did not
    necessarily require such a result. Because the STB had
    found inadequate justification for reopening the
    identification stage, it continued to decline to do so. The
    STB solicited anew the ACHP's comments on mitigation and
    the MOA.
    The ACHP, on February 26, 1999, formally referred the
    matter to the Secretary of the Interior and informed the
    STB that, pending receipt of the Keeper's findings, it
    believed that the identification and evaluation r equirements
    had not been met. The ACHP further asserted that, if the
    STB continued its efforts to finalize the draft MOA, it would
    be in violation of its statutory and regulatory obligations. In
    April 1999, the Keeper issued a determination that the
    entire 66.5-mile Enola Branch line was eligible for
    designation in the National Register. The determination
    stated:
    Constructed by the Pennsylvania Railroad between
    1902 and 1906, the entire 66.5 mile Enola Branch Line
    is eligible for the National Register of Historic Places for
    its historic and engineering significance. Built as a
    significant component of the Pennsylvania Railr oad
    15
    system, the Enola Branch line was an important
    engineering feat of the early 20th century. The Enola
    Branch Line differed from other railroads of the period
    in that it was designed to have no contact with other
    vehicular routes, and it was to run almost completely
    level and in a straight line. This straight line, with low
    radius curves and very little change in grade, pr ovided
    improved and efficient delivery of fr eight by rail.
    Building the line necessitated vast amounts of cutting
    and filling and the construction of numerous stone
    bridges and culverts built by skilled Italian stone
    masons.
    On August 13, 1999 (1999 Order), the STB denied FAST's
    petition for reconsideration of the 1997 Or der, holding that
    FAST had not made the required showing of material error,
    new evidence, or changed circumstances warranting
    reconsideration. The Board declined to give substantial
    weight to the one new piece of evidence, a letter to the
    Trust from the Curator of Transportation of the National
    Museum of American History.7 The STB found that the
    letter could have been presented earlier and noted that the
    Curator took no formal position in the matter . The STB also
    declined to reconsider the import of the TWO letter, noting
    that FAST still had not explained the discr epancy between
    that letter and the SHPO's formal position on the record
    before the STB that the only issue remaining in the
    proceeding was mitigation.8 The STB similarly rejected the
    Keeper's statement of eligibility, describing it as"pro
    forma." The STB emphasized that its identification decision
    had been based on an agreement with the SHPO about the
    properties to be protected (all of the bridges, later narrowed
    to 32 bridges and 36 archaeological areas) and that under
    these circumstances, to restart the identification process to
    _________________________________________________________________
    7. That letter, dated April 2, 1997, detailed the history of the line and
    called its significance "unquestioned." The Curator stated that he could
    take "no formal position in such a legal pr oceeding," but he stated that
    he supported the development of the line, intact, as a recreational and
    educational trail.
    8. The STB emphasized several letters from the SHPO, post-1994, that
    appear to reflect this same view.
    16
    include the entire rail line "would add inexcusable delay to
    a process that has already taken much too long."
    The STB then terminated the consultation pr ocess and
    removed the S 106 condition, subject only to Conrail's
    compliance with the terms of the proposed, although
    unexecuted, MOA. In terminating consultation, the STB
    emphasized the steps it had taken throughout this process.
    It found that "further consultation would be fruitless." It
    further noted the fact that the ACHP would not r espond on
    the issue of mitigation, despite the STB's r equest for it to do
    so, and "instead continues to seek to dictate the[STB's]
    procedures and compel us to reopen this case and declare
    this entire rail line historic." The STB considered the
    ACHP's letters in January and February 1999 to be its
    comments and recommendations on the undertaking and
    on termination of consultation; having taken them into
    account, the STB determined that it had complied with
    S 106 and that the process was complete.
    The record indicates that Conrail/Nor folk has
    consummated abandonment of the rail line, other than the
    bridges. According to Norfolk, it has been more than ten
    years since there was activity on the line and more than
    eight years since there was any railroad equipment or
    property on the land. All tracks, ties, rails, signage, and
    equipment have been stripped from the pr operty.
    III. JURISDICTION
    The STB, as statutory successor to the ICC under the
    ICC Termination Act, had jurisdiction over Conrail's
    petition to abandon the Enola Branch and could do so
    under the exempt procedures. See 49 U.S.C.
    SS 10501(a)(1)(A), 10502(a)(1), 49 C.F .R. S 1152.50. We have
    exclusive jurisdiction to review a final or der of the STB,
    pursuant to 28 U.S.C. SS 2321 and 2342(5), pr ovided that
    the petition for review was filed by the aggrieved party
    within 60 days of entry of the final order . See 28 U.S.C.
    S 2344. FAST filed the instant petition for review within 60
    days of service of the Board's 1999 Order .
    The STB and intervenor Norfolk did, however , raise two
    preliminary issues questioning our jurisdiction to review
    17
    the STB's order and the STB's jurisdiction should this
    matter be remanded.
    A. WHICH ORDER IS BEING REVIEWED?
    The STB argues that FAST actually is challenging the
    1990 Order that limited the scope of potentially historically
    eligible properties to the 83 bridges on the rail line. It is the
    STB's position that direct judicial review of the 1990 Order
    is precluded by S 2344, which requir es that a petition for
    review of final agency action be filed within 60 days. See 28
    U.S.C. S 2344; see also ICC v. Brotherhood of Locomotive
    Eng'rs, 
    482 U.S. 270
    , 277 (1987). Once that 60-day period
    has passed, an agency order is no longer subject to judicial
    review. See 
    id. The STB
    contends that F AST is precluded
    from making any arguments that in any way address the
    manner in which the STB identified historic pr operties or
    its determination that only some bridges and archaeological
    areas are eligible for historic pr otection. The STB argues
    that we have jurisdiction to review only the plan for
    mitigation as to the bridges and the decision to ter minate
    consultation. It suggests that we may not addr ess any
    issues relating to the identification of historic properties.
    We disagree and conclude that we do have jurisdiction to
    review the entire matter, including those aspects of the
    STB's decisions relating to the identification of eligible
    historic properties on the rail line. First, in the 1997 Order,
    the STB rejected FAST's request that the preservation
    requirement imposed in the 1990 Or der be broadened to
    apply to the entire Enola Branch line. However , the 1997
    Order expressly stated that "[t]his proceeding is reopened."
    When the STB "reopens a proceeding for any reason and,
    after reconsideration, issues a new and final order setting
    forth the rights and obligations of the parties, that order--
    even if it merely reaffirms the rights and obligations set
    forth in the original order--is reviewable on its merits."
    
    BLE, 482 U.S. at 278
    (citing United States v. Seatrain Lines,
    Inc., 
    329 U.S. 424
    (1947)). The STB urged that the
    reopening must be understood in context, that the
    proceeding was reopened only for the limited purpose of
    narrowing the scope of the historic condition. However,
    reopening a proceeding "for any r eason," even if only to
    18
    reaffirm the original order , gives us jurisdiction to review
    every aspect of the reopening order . See 
    BLE, 482 U.S. at 278
    .
    Reopening in this case, even if only to narr ow rather than
    expand the original identification decision, makes the
    issues of identification reviewable. The STB cannot claim
    that identification was complete prior to 1997, yet still
    reopen the proceeding in order to consider some aspect of
    identification. That further consideration is subject to
    review, both as to whether it was proper to narrow the
    scope of the properties to be protected and also as to
    whether it was improper not to expand the scope of the
    protected properties. In short, the STB's explicit order to
    reopen this proceeding meant reopening for all purposes,
    thereby bringing the issue of identification back into play
    and making it subject to review at this time.
    Second, FAST's 1996 petition (resolved in the 1997
    Order), seeking reopening of the pr oceedings for the
    purpose of reconsidering and expanding the identification
    decision, was based on a claim of new evidence or changed
    circumstances, particularly evidence of changed opinions
    and perceptions of how much of the rail line would be
    eligible for the National Register. Wher e a motion to reopen
    is based on non-pretextual arguments about new evidence
    or changed circumstances, the refusal to r eopen or
    reconsider a decision itself is reviewable for abuse of
    discretion. See 
    BLE, 482 U.S. at 284
    ("If the petition that
    was denied sought reopening on the basis of new evidence
    or changed circumstances review is available and abuse of
    discretion is the standard."); Fritsch v. ICC, 
    59 F.3d 248
    ,
    252 (D.C. Cir. 1995) (interpreting BLE to permit merits
    review of a refusal to reopen wher e the motion is based on
    non-pretextual grounds of new evidence or changed
    circumstances); Friends of Sierra R.R., Inc. v. ICC, 
    881 F.2d 663
    , 666-67 (9th Cir. 1989) ("The or der denying [the]
    petition is subject to review only if the petition sought
    reopening on the basis of `new evidence' or`substantially
    changed circumstances.' "). Even assuming that the STB's
    1997 Order declined to reopen for the purposes of
    expanding the historic condition, that refusal to reopen is
    itself subject to judicial review. Under BLE, we would have
    19
    jurisdiction to determine whether the Boar d's refusal to
    expand the condition was an abuse of discretion.
    The STB argues that FAST did not actually submit any
    new or newly discovered evidence because the opinions of
    the ACHP, the SHPO, the Keeper, and the Curator,
    regarding the historic eligibility of the entire line, were
    available all along and could have been presented earlier.
    The STB contends, therefore, that F AST actually sought
    reopening and reconsideration based on"material error,"
    the denial of which motion unquestionably would not be
    subject to judicial review. See 
    BLE, 482 U.S. at 280
    (holding that "where a party petitions an agency for
    reconsideration on the ground of `material error,' . . . `an
    order which merely denies rehearing' . . . is not itself
    reviewable.").
    The STB's argument fails because it conflates the
    jurisdictional and merits analyses. Whether the evidence
    presented actually is new or newly discover ed, as opposed
    to newly presented, goes to the merits of whether the
    refusal to reopen or reconsider a prior decision was proper
    or lawful. It does not go to the jurisdiction of the court of
    appeals to review that refusal. Jurisdiction and
    reviewability are based on the fact that the motion before
    the STB alleged the existence of new evidence or changed
    circumstances. See Friends of 
    Sierra, 881 F.2d at 666
    ("[W]e
    determine reviewability solely by examining the bases
    advanced in the petition to reopen."). That basis for the
    motion, assuming it is not a pretext, is sufficient alone to
    confer jurisdiction to review the Board's refusal to expand
    the identified historic properties and pr otect the entire rail
    line.
    From the record before us, we conclude that FAST sought
    reopening based on new evidence or changed
    circumstances, not material error, such that the refusal to
    reopen is subject to judicial review.
    FAST moved within 60 days for reconsideration of the
    1997 Order, thus tolling the period for seeking judicial
    review of the 1997 Order until reconsideration was denied.
    The 1999 Order denied reconsideration of the refusal to
    reopen and the petition for review wasfiled within 60 days.
    20
    We have jurisdiction, therefore, to review the 1997 Order
    through its denial by the 1999 Order . See 
    BLE, 482 U.S. at 279
    (stating that a petition for reconsideration tolls the
    period for judicial review of the original or der, which can be
    appealed directly after the petition for r econsideration is
    denied).
    B. THE STB'S JURISDICTION ON REMAND
    Norfolk, as intervenor on behalf of the STB, raises a
    different argument, going to the STB's jurisdiction on
    remand. Norfolk suggests that, because it has abandoned
    the Enola Branch, the STB no longer would have
    jurisdiction on remand to make any deter minations as to
    the historic status of the line as a whole or to impose
    mitigation conditions on any non-bridge property. It argues
    that any decision vacating the STB's original identification
    decision and remanding the case to the STB would be futile
    because, beyond the bridges already identified, the STB
    would be without the power to impose any historic
    conditions on the abandoned line as a whole.9
    It is true, generally, that once a carrier abandons a rail
    line, the line no longer is part of the national transportation
    system and the STB's jurisdiction terminates. See Preseault
    v. ICC, 
    494 U.S. 1
    , 5-6 n.3 (1990). Unless the STB attaches
    post-abandonment conditions to a certificate of
    abandonment or exemption, such as requir ements under
    S 106, the authorization of abandonment ends the Board's
    regulatory mission and its jurisdiction. See id.; Hayfield N.
    R.R. Co., Inc. v. Chicago & Northwestern T ransp. Co., 
    474 U.S. 622
    , 633-34 (1984). The determination of whether a
    railroad has abandoned a line hinges on the railroad's
    objective intent to cease permanently or indefinitely all
    _________________________________________________________________
    9. Norfolk raises the issue of the STB's jurisdiction for the first time
    on
    appeal. In opposing FAST's motion to r eopen before the STB, Norfolk
    never suggested that the STB was without jurisdiction to expand the
    scope of the historical condition on the rail line. Yet if the STB would
    have had jurisdiction to expand the historical condition in the 1997
    Order, it is not clear why the STB would lack jurisdiction to do the same
    on remand from our determination that the 1997 Order declining to
    reopen was in error.
    21
    transportation service on the line. See Birt v. Surface
    Transp. Bd., 
    90 F.3d 580
    , 585 (D.C. Cir. 1996) (citation and
    internal quotation marks omitted). Abandonment is
    considered consummated when the rail line is fully
    abandoned. See Consolidated Rail Corp. v. Sur face Transp.
    Bd., 
    93 F.3d 793
    , 798 (D.C. Cir. 1996).
    We reject Norfolk's argument because there has been no
    STB finding that Norfolk consummated abandonment of the
    rail line as an entire property. Following the 1990 Order,
    Conrail removed all remnants of the railr oad line from the
    property, including all tracks, ties, rails, signage, and
    equipment. According to Norfolk, it has been more than ten
    years since there was activity on the pr operty, more than
    eight years since there was railroad equipment on the
    property, and more than seven years since Conrail
    attempted to negotiate converting the rail into a trail.
    But the historical eligibility of the line as a whole does
    not require the presence of the tracks and other railroad
    equipment. The historically eligible property, as found by
    the Keeper and urged by FAST, is the rail line itself,
    including the trail and all of the bridges. The issue is
    whether Norfolk has abandoned, sold, or otherwise
    disposed of any portion of that property, a point on which
    the record is silent. If, on remand, the STB concludes that
    Norfolk has disposed of some portion of the line, the STB
    will be without power to expand the historical condition to
    cover that property already sold. But the STB otherwise
    does have the power to expand the historical condition to
    cover all property not abandoned and to r equire Norfolk to
    preserve the status quo and not to sell or otherwise disturb
    or dispose of the rail line pending proper completion of the
    S 106 process.
    IV. HISTORIC ELIGIBILITY OF THE ENOLA LINE
    We now proceed to the merits of this petition, whether
    the STB erred in carrying out its statutory obligations
    under S 106. Our review is governed by the Administrative
    Procedure Act (APA), 5 U.S.C. S 706(2), which provides that
    a court of appeals may "hold unlawful and set aside agency
    action, findings, and conclusions found to be arbitrary,
    22
    capricious, an abuse of discretion, or otherwise not in
    accordance with law." 5 U.S.C. S 706(2)(A); see Consolidated
    Rail Corp. v. United States, 
    855 F.2d 78
    , 85 (3d Cir. 1988)
    (applying S 706 to review of ICC decision).
    As we set out in Part 
    I.B, supra
    , the NHP A is a
    procedural rather than a substantive statute, designed to
    ensure that federal agencies take into account the effect on
    historic places of federally regulated undertakings. See
    Morris County 
    Trust, 714 F.2d at 278-79
    . The statute
    represents a balance between the goals of historic
    preservation and the needs of business and community
    development. See 
    id. at 280;
    37 C.F.R. S 800.1(a). Our
    concern on review under the NHPA is less with the
    substantive results reached by the STB on the historic
    eligibility of the Enola Branch than with the pr ocedures
    and reasoning the STB followed in reaching those results.
    See Morris County 
    Trust, 714 F.2d at 280
    . We have agreed
    that S 106 is a "stop, look, and listen" provision, requiring
    an agency to acquire and consider infor mation prior to
    making a decision and approving a federal undertaking. See
    Concerned 
    Citizens, 176 F.3d at 695
    -96 (citing Illinois
    Commerce 
    Comm'n, 848 F.2d at 1260-61
    ).
    The issue, therefore, is whether the STB touched all the
    procedural bases in limiting the scope of the identified
    historic properties on the line to the 32 bridges and 36
    archaeological areas, in refusing to expand that
    identification in 1997 and 1999, in unilaterally approving
    the mitigation plan outlined in the draft MOA and the 1999
    Order, and in terminating consultation in the 1999 Order.
    We conclude that the STB did not touch all the bases. The
    STB's decision to terminate the process as it did, and to
    provide only limited historic protection, must be vacated
    and this matter remanded to the STB for further
    proceedings.
    A. IDENTIFICATION
    Although there would appear to be a lack of constructive
    public dialogue in the whole of the S 106 identification
    process, FAST did not seek review of the 1990 Order at the
    time it issued, nor has FAST formally complained about the
    23
    early stages of the S 106 identification. W e will begin our
    analysis therefore with the events occurring after FAST's
    1996 petition to reopen and expand the historic condition.
    In the 1997 and 1999 Orders, the STB concluded that the
    TWO letter and the letter from the Curator wer e not new or
    newly discovered evidence in that both pieces of
    information were available prior to their submission to the
    STB in 1996. The STB also discounted the SHPO's position
    as stated in the TWO letter because it was inconsistent with
    its formal position before the STB and the inconsistency
    was not explained. In addition, in the 1999 Or der, the STB
    rejected the Keeper's statement as "pr o forma" and not
    justifying reopening the identification phase because doing
    so "would add inexcusable delay to a process that has
    already taken much too long."
    The identification process must, however , be a fluid and
    ongoing one. "The passage of time, changing per ceptions of
    significance, or incomplete prior evaluations may require
    the Agency Official to reevaluate properties previously
    determined eligible or ineligible." 36 C.F .R. S 800.4(c)(1)
    (emphasis added). The STB's own regulations also permit it
    to reopen or reconsider a prior action because of new
    evidence or substantially changed circumstances. See 49
    U.S.C. S 722(c). If we read S 722(c) together with
    S 800.4(c)(1), these provisions suggest that evidence of
    changed perceptions of historical significance constitutes
    evidence of substantially changed circumstances, thus
    permitting reopening or reconsideration.
    In the 1997 and 1999 Orders, however, the STB focused
    only on whether FAST had submitted new evidence; it did
    not consider whether FAST had submitted evidence of
    substantially changed circumstances. This ruling ignores
    the "changed circumstances" language ofS 722(c).
    Furthermore, the STB failed to consider the Keeper's
    statement that the entire Enola Branch line was eligible for
    designation in the National Register. The ACHP had taken
    the position that the Keeper's findings wer e necessary
    before the identification process could be completed. Once
    the ACHP had brought the Keeper into the pr ocess, the
    Keeper's conclusions had to be considered. As we noted in
    Part 
    I.B, supra
    , the Keeper has been held to have
    24
    independent authority to determine whether a property
    should be listed in the National Register. See Moody Hill
    
    Farms, 205 F.3d at 558
    .
    The STB ignored the Keeper's determination because of
    its "untimeliness" and the STB's concer n that considering it
    would impose additional, inexcusable delay on theS 106
    process. This consideration of late timing is, however,
    inconsistent with S 800.4(c)(1). If the passage of time can be
    a basis for reevaluation of the identification decision under
    the regulations, it cannot at the same time be a basis for
    refusing to consider evidence of changed per ceptions of
    historical significance. By focusing on the timing of the
    Keeper's statement and refusing to consider and address its
    merits, the STB introduced an improper consideration into
    the identification process. The fact that the STB and the
    SHPO had previously agreed that the bridges were the only
    properties that were historically eligible does not and
    cannot outweigh, without further explanation, the Keeper's
    determination, whenever that determination was rendered.
    See Moody 
    Hills, 205 F.3d at 558-59
    (stating that the
    Keeper is not bound by the historic determinations of state
    and local authorities).
    The STB also dismissed the Keeper's statement as"pro
    forma" and therefore not entitled to serious weight.
    However, the STB did not indicate in what way the
    statement was pro forma, nor did it indicate what
    additional information the Keeper should have presented in
    its evaluation. The Keeper's evaluation included a lengthy
    paragraph describing the Enola Branch's overall historic
    significance; the Board has not explained why the Keeper's
    position was not entitled at least to some consideration.
    The STB is correct in contending that, because it and the
    SHPO initially did not disagree as to the scope of eligible
    properties, the STB was not requir ed under the regulations
    to request a determination from the Secretary of the
    Interior or from the Keeper. Such a r eferral is required only
    if the STB and the SHPO do not agree. See 36 C.F.R.
    S 800.4(c)(2). However, that same r egulation provides that
    the Secretary or the ACHP can request such a
    determination at any time, whether or not the STB and the
    SHPO disagree. See 36 C.F.R.S 800.4(c)(2). Given the
    25
    authority of the Keeper, it must follow that once that
    determination has been obtained, it is entitled to some
    attention by the agency.
    Moreover, the fact that the SHPO's position in the TWO
    letter in 1994, that the entire line was eligible for the
    National Register, appeared to be a change from its earlier
    position before the STB was not sufficient gr ounds for the
    STB not to consider that letter as evidence of changed
    perceptions. The STB argues that nothing in the statutes or
    regulations requires it to rethink its decisions whenever an
    affected party changes its mind. See Connecticut Trust for
    Historic Preservation v. ICC, 841 F .2d 479, 484 (2d Cir.
    1988). However, Connecticut Trust involved a potential
    purchaser of the abandoned rail property that changed its
    mind about which portions of the line it wanted to
    purchase. See 
    id. That is
    significantly different from a
    change of position by the SHPO, which is statutorily
    empowered to advise the STB throughout theS 106 process
    and is not an affected party in the same way as a would-be
    purchaser. The SHPO's revised view as to the eligibility of
    the entire rail line may represent a changed perception of
    historic significance or be the result of a more complete
    evaluation of the property. The SHPO's changed perception
    should have received some consideration on its merits and
    should not have been rejected out of hand as an
    unexplained change of heart.
    The STB similarly erred in not giving sufficient
    consideration to the views of the ACHP. While the ultimate
    decision on an undertaking remains with the agency
    implementing it, the ACHP must be affor ded the
    opportunity to comment and its comments must be taken
    into account by the agency in rendering its decision. See
    Concerned 
    Citizens, 176 F.3d at 695
    (quoting Waterford
    Citizens' Ass'n v. Reilly, 
    970 F.2d 1287
    , 1290 (4th Cir.
    1992)). The agency must make clear that it consider ed the
    ACHP's opinions, see Concerned Citizens , 176 F.3d at 696,
    instead of dismissing them as an attempt by the ACHP to
    "dictate" the STB's procedures.
    The ACHP formally became involved in the S 106 process
    in March 1998, at the request of F AST, during the
    pendency of FAST's motion for reconsideration. ACHP
    26
    involvement was not required at the identification stage and
    the STB did not err in not immediately seeking ACHP
    comments on identification. However, the ACHP is identified
    as a source of guidance and advice regar ding the
    application of the regulations; it also is empowered to enter
    the S 106 process at any time that it determines that its
    involvement is necessary to ensure that the purposes and
    requirements of S 106 are met. See 36 C.F.R. S 800.2(b).
    Once the ACHP entered the proceedings, the STB, although
    not required to follow the comments and suggestions of the
    ACHP at any stage, was required to take these comments
    into account and to indicate that the comments wer e given
    genuine attention on their merits. The relevant"agency
    must demonstrate that it has read and consider ed those
    recommendations" and "it must make clear in the record
    that the ACHP's comments were taken seriously." See
    Concerned 
    Citizens, 176 F.3d at 696
    .
    The record here shows that the ACHP's comments were
    not taken seriously.10 In several letters to the STB following
    its decision to participate in the consultation, the ACHP
    raised its concerns about the way in which historically
    eligible properties had been identified and its desire to see
    further consideration of what properties on the rail line
    _________________________________________________________________
    10. The parties dispute the amount of defer ence or weight to be accorded
    to the ACHP's interpretation of its regulations. FAST relies on our
    statement in Morris County that "the Advisory Council's regulations are
    particularly persuasive concerning the pr oper interpretation of NHPA."
    See Morris 
    County, 714 F.2d at 280
    . Nor folk points to the statements in
    Concerned Citizens that found no support for the conclusion that the
    ACHP's judgments were entitled to great weight. See Concerned 
    Citizens, 176 F.3d at 696
    n.6. FAST argues that Concerned Citizens was a case
    challenging the Federal Highway Administration's compliance with S 4(f)
    of the Department of Transportation Act, in which the ACHP plays no
    role. By contrast, the instant case is a challenge to compliance with the
    ACHP's own regulations under the NHPA. W e need not resolve this
    matter because, even assuming that the ACHP's judgment is entitled
    only to minimal weight and that the agency mer ely must afford these
    comments some attention and consideration, see Concerned 
    Citizens, 176 F.3d at 696
    , we conclude that the STB in the instant case did not
    accord the ACHP's comments even that minimal degree of attention and
    consideration.
    27
    should be identified as historic. The STB did not respond to
    these concerns.
    Moreover, any delay in ACHP participation and comment
    may be attributed, at least in part, to the STB. The STB
    apparently did not, as required, notify the ACHP of its
    determination of adverse effects at the time of its initial
    presumptive finding of such effects in 1990. See 36 C.F.R.
    S 800.6(a)(1) (requiring notification of the ACHP upon a
    finding of adverse effects). The STB also did not involve the
    ACHP when requested to do so by FAST , sometime prior to
    March 1998. Instead, FAST was for ced to contact the ACHP
    itself, pursuant to 36 C.F.R. S 800.6(a)(1)(ii). As a result, the
    ACHP did not become involved in the proceedings until
    March 1998.
    Finally, the STB never mentioned or gave any
    consideration to the detailed statement by Lancaster
    County, in its 1989 objection to Conrail's Notice of
    Exemption, as to the historic significance of the line as a
    whole. The substance of this statement was similar to the
    comments made by the Keeper in its 1999 deter mination of
    eligibility. Although the County did not expr essly request a
    historic condition on the abandonment of the line, its
    comments provided the STB with initial evidence as to the
    historical significance of the rail line as a linear source.
    Like any other evidence from an interested party, this was
    entitled to some consideration by the Board in identifying
    historic properties. However, the r ecord does not reflect that
    the Board ever recognized or consider ed the merits of this
    statement.
    B. TERMINATION OF CONSULTA TION
    FAST also challenges the manner in which the STB
    terminated the regulatory consultation. After declining to
    reconsider FAST's request to expand the historic condition
    and protect the entire rail line, the STB unilaterally
    terminated consultation on mitigation, unilaterally
    terminated the entire S 106 pr ocess, and imposed the terms
    of the unexecuted MOA, finding that it "constitutes
    appropriate historic mitigation for the bridges at issue."
    28
    The terms of the MOA were established following
    negotiations among the STB, Conrail, and the SHPO; all
    three agreed to terms, including r ecordation of five bridges,
    funding of the film, transfer of certain bridge pr operties to
    local municipalities, and payment of money by Conrail for
    upkeep of those bridges. However, the SHPO declined to
    sign the MOA, citing the ACHP's desire to consult in the
    process. At that point, the STB was requir ed to invite the
    ACHP formally to participate in the consultation, and, if the
    ACHP declined to consult, to obtain the ACHP's comments
    on the undertaking and on the proposed mitigation plan.
    See 36 C.F.R. SS 800.6(b)(1)(v), 800.7(c)(2). The STB did
    submit a copy of the MOA to the ACHP for comment and
    approval; the ACHP expressly declined to comment on the
    MOA or the mitigation plan, focusing its comments instead
    on what it found to be deficiencies in the S 106 process
    generally and the need to reconsider identification.
    The STB certainly has the power to declare consultation
    at an impasse and to terminate, if it finds that further
    consultation would not be productive. See 36 C.F.R.
    S 800.7(a). However, the applicable r egulations require that,
    if the STB does terminate consultation, it must give notice
    of that termination to the ACHP, see 36 C.F.R. S 800.7(a)(1);
    allow 45 days for ACHP comments on termination, see 36
    C.F.R. S 800.7(c)(2); and take those comments into account,
    giving them genuine attention and consideration, in
    terminating consultation and reaching afinal decision. See
    36 C.F.R. S 800.7(c)(4). Only after r eceipt and consideration
    of those comments may the STB complete the ter mination
    of the process and implement a mitigation plan, provided
    that it expressly take such comments into account in
    rendering that final decision. See Concer ned 
    Citizens, 176 F.3d at 696
    . The STB did not meet these r equirements for
    termination.
    We can understand the impatience of the STB to resolve
    this expedited abandonment. Nevertheless, when
    procedures are established by law, those procedures must
    be followed. Because the STB did not follow the r equired
    procedures, we conclude that it abused its discretion in
    implementing the MOA and in terminating the consultation.
    For these reasons, the 1997 and 1999 Or ders will be
    vacated and this matter will be remanded to the STB.
    29
    In determining to vacate and remand this matter, we in
    no way suggest that FAST is entitled to the r elief it seeks.
    We take no position as to whether the entir e Enola Branch
    is eligible for inclusion in the National Register or as to
    whether there is sufficient evidence of changed perceptions
    of historical significance or changed circumstances to
    justify preserving the entire line. W e also take no position
    as to whether the mitigation plan favored by the STB is
    proper although we note that the ultimate decision is left to
    the STB after due consideration of comments fr om
    interested parties. See Concerned 
    Citizens, 176 F.3d at 696
    .
    We also take no position as to whether consultation is at an
    impasse and whether the process properly should be
    terminated. We hold only that, on r emand, the STB must
    conduct the S 106 process in accor dance with the
    regulations. It must consider the comments and opinions of
    the Keeper, the ACHP, and other inter ested parties as to the
    scope of the eligible historic properties and as to a proper
    mitigation plan. If the STB again decides that further
    consultation is fruitless and that the S 106 process should
    be termination, it must follow the procedural track
    established by the regulations for termination.
    V. CONCLUSION
    For the foregoing reasons, the motion of the STB to
    dismiss the petition for review is denied. The petition for
    review is granted and the 1997 and 1999 Or ders of the STB
    are vacated. This matter is remanded to the Surface
    Transportation Board for further pr oceedings consistent
    with this opinion.
