    OPINION
    _________________
    COLE, Circuit Judge. After a three-week jury trial, James Mathis and Donald
    Fillers were convicted of conspiracy, 18 U.S.C. § 371, and violations of the Clean Air
    Act, 42 U.S.C. § 7413(c). Fillers was also convicted of making a false statement,
    1
    Nos. 12-6256/6354        United States v. Mathis, et al.                           Page 2
    18 U.S.C. § 1001(a)(2), and obstruction of justice, 18 U.S.C. § 1519. The district court
    denied Fillers’s motion to suppress and Mathis’s and Fillers’s motions for a judgment
    of acquittal. It sentenced Mathis to 18 months’ imprisonment and Fillers to 44 months’
    imprisonment. Mathis and Fillers raise several challenges to their convictions and
    sentences, but ultimately we affirm.
    I. BACKGROUND
    Donald Fillers (“Fillers”) and his brother Gary formed Watkins Street Project,
    LLC, in 2003 to develop an unused factory site in Chattanooga, Tennessee. They
    planned to demolish the factory and sell the salvageable materials, but they knew the site
    contained asbestos. Asbestos is a fibrous mineral formerly used as insulation, and some
    forms of asbestos crumble and release microscopic fibers into the air when disturbed.
    Inhalation of asbestos fibers can cause fatal and debilitating illnesses.
    The Clean Air Act lists asbestos as a hazardous pollutant, and the Environmental
    Protection Agency has developed work-practice standards for the demolition of
    buildings that contain asbestos. The standards require the removal of all asbestos before
    any demolition that would dislodge the material. These standards also specify removal
    procedures. For example, asbestos materials must be wetted before removal, lowered
    to the ground rather than dropped, labeled, and disposed of at a site authorized to accept
    asbestos. Owners and operators of demolition activities must also give notice, including
    a description of the location and amount of asbestos, to the EPA ten days before
    demolition. The Clean Air Act makes it a crime for individuals to violate these
    standards.
    Gary hired Alternative Actions, Inc., a certified asbestos surveying company, to
    estimate the amount of asbestos at the factory site and the cost of removal. The survey
    revealed a large amount of duct, pipe, and equipment insulation containing asbestos.
    Alternative Actions estimated that it would cost $214,650 to remove the contaminated
    material safely.
    Nos. 12-6256/6354        United States v. Mathis, et al.                          Page 3
    Fillers then hired Mathis Companies, Inc., a demolition company owned by
    James Mathis, to tear down the factory in exchange for some of the salvageable
    materials. Mathis was also required to use a certified contractor to remove the asbestos.
    Mathis requested a bid from SCI Remediation, which toured the site, reviewed the
    Alternative Actions survey, and estimated that it would cost $129,250 to remove the
    asbestos. Fillers believed that the removal could be done for much less—about $20,000
    total—so he rejected the SCI bid and told Mathis that Watkins Street would find a
    different asbestos-removal company.
    Fillers asked two other asbestos-removal companies to submit estimates. He
    provided the Alternative Actions survey to one company, which returned a bid of
    $126,542. Fillers provided an incomplete version of the survey to the other company,
    which ultimately decided not to bid.         Gary then contacted ADC Systems, an
    asbestos-removal company managed by Halbert Warden and his father. Fillers told
    ADC that no asbestos survey had been prepared. Based on an “initial walk through,”
    ADC estimated the cost of removal at $28,900, and the Fillers brothers accepted the bid.
    In August 2004, Mathis visited the Chattanooga-Hamilton County Air Pollution
    Control Bureau to submit the 10-day notice and permit application for demolition. The
    Bureau works with the EPA to enforce the Clean Air Act in Chattanooga. The estimated
    amount of asbestos in the notice was far less than in the Alternative Actions survey.
    Kathy Jones, the Bureau’s air monitoring manager and asbestos coordinator, accepted
    the notice from Mathis and later contacted Fillers to verify the amount of asbestos and
    request a copy of the survey. Fillers did not send the survey, but instead provided a
    revised asbestos estimate that was still far less than the survey’s estimate. Jones
    approved the application and sent permits to Warden, Mathis, and Gary.
    ADC began removing the asbestos. ADC’s initial contract was limited to the
    factory’s boiler room, but Warden noticed “mass bunches of asbestos” outside the ADC
    work area. Warden mentioned the additional asbestos to Gary, and Watkins Street
    increased the scope of ADC’s work order. This change, however, still did not cover all
    the asbestos at the site: Warden later testified that ADC removed “[m]aybe, like,
    Nos. 12-6256/6354         United States v. Mathis, et al.                            Page 4
    1/100th” of the asbestos listed in the Alternative Actions survey. After finishing the
    work they were authorized to perform, ADC left the site.
    Watkins Street hired temporary laborers to remove debris and salvage materials
    from the site. These workers were not equipped with protective gear or trained to
    remove asbestos. Fillers helped supervise the team, which did not take special
    precautions with material (such as insulation) that likely contained asbestos. The
    workers used power tools to cut through pipes that were wrapped in insulation, threw
    debris out of windows so that it fell to the ground, removed insulation by hand, and
    otherwise disposed of insulation without wetting, containerizing, or labeling it.
    Mathis and his company would then demolish each section the salvage team
    cleared. The salvage team worked in the afternoons and at night; the demolition team
    worked in the mornings. Mathis knew, however, that the salvage team was improperly
    removing asbestos because Warden told him as much when he returned to the site after
    ADC had finished its work. During this visit, Warden pointed out loose materials
    containing asbestos strewn about the site. Mathis replied, “Halbert, Don is not going to
    pay for anything else.” Warden later visited the site two more times, each time telling
    Mathis that there was asbestos “all over the ground.” Mathis responded that Fillers
    would not pay for further asbestos removal and that he was tired of arguing with Fillers
    about it. Mathis then continued demolishing the factory.
    The demolition and salvage teams’ work dispersed dust throughout much of the
    site and surrounding neighborhood. An employee of a nearby daycare facility later
    testified that the air in the area was so contaminated that the children at the daycare were
    unable to play outside.
    In September 2005, an investigator from the Air Pollution Control Bureau, John
    Schultz, observed the site during a routine patrol. He later testified that the site “looked
    like a bomb had gone off,” and that there were “debris piles over the entire city block.”
    Because of disagreements between Mathis and Fillers, no one had worked on the site for
    at least a month. There were no signs, fences, or security guards to keep the public off
    of the site. Schultz thought the debris contained asbestos, so he briefly explored the
    Nos. 12-6256/6354        United States v. Mathis, et al.                            Page 5
    demolition area. He returned the next day with Kathy Jones, who reported that “[t]he
    site appeared to be littered with suspect asbestos-containing materials.” They collected
    samples of the materials, which later tested positive for asbestos.
    The Bureau then contacted the EPA, which sent an emergency response
    coordinator to the site. The EPA coordinator declared the site an imminent threat to
    human health and the environment and ordered Watkins Street to clean up the debris
    using a certified asbestos-removal company. Watkins Street completed the cleanup in
    October 2005.
    The United States charged Mathis and Fillers, among others, with conspiracy to
    defraud the United States and to violate the Clean Air Act (count 1), substantive
    violations of the Clean Air Act (counts 2–4), and making false statements (counts 8 and
    9). The United States also charged Fillers with other substantive violations of the Clean
    Air Act (counts 5–7) and obstruction of justice (count 11).
    A jury convicted Mathis of conspiracy and two substantive violations of the Act:
    failure to file an accurate 10-day notice, and commencement of demolition prior to
    removing asbestos from the site. After a week-long sentencing hearing, the district court
    determined that Mathis’s guidelines range was 27–33 months. The court sentenced
    Mathis to 18 months’ imprisonment.
    The jury convicted Fillers of conspiracy, six substantive violations of the Act,
    making false statements, and obstruction of justice. The substantive violations included
    the notice and removal violations, as well as failure to have present an individual trained
    in the work-practice standards during demolition, failure to wet the material containing
    asbestos during removal, failure to lower the material properly, and failure to
    containerize and timely dispose of the material. The district court determined that
    Fillers’s guidelines range was 46–57 months, and it sentenced him to 44 months’
    imprisonment.
    Mathis and Fillers now challenge their respective convictions and sentences. We
    have jurisdiction to hear the appeal under 18 U.S.C. §§ 1291 and 3742.
    Nos. 12-6256/6354        United States v. Mathis, et al.                             Page 6
    II. ANALYSIS
    Fillers attacks his convictions and sentence with arguments in four areas:
    warrantless search and seizure, admission of certain testimony at trial, sufficiency of the
    evidence, and calculation of sentencing guidelines. Mathis joins Fillers with arguments
    in the last three areas. We address each in turn.
    A.      Warrantless Search and Seizure
    Fillers asks us to reverse the district court’s denial of his motion to suppress the
    asbestos-containing samples. When considering a motion to suppress, we review a
    district court’s findings of fact for clear error and its conclusions of law de novo. United
    States v. Davis, 
    514 F.3d 596
    , 607 (6th Cir. 2008). We also consider the evidence “in
    the light most likely to support the district court’s decision.” 
    Id. (citation and
    internal
    quotation marks omitted).
    The district court adopted the magistrate judge’s report and recommendation,
    which found that the Bureau employees’ warrantless search and seizure did not violate
    the Fourth Amendment. Entry onto and search of the property was lawful, the
    magistrate judge reasoned, because Fillers had no subjective expectation of privacy in
    the site and because the site qualified as an “open field.” Seizure of the samples was
    lawful, the magistrate judge concluded, under the plain view doctrine. We agree.
    1.      Warrantless Searches
    When challenging the admission of evidence under the Fourth Amendment, it is
    the defendant’s burden to show that he had a legitimate expectation of privacy in the
    area searched or items seized. United States v. Mastromatteo, 
    538 F.3d 535
    , 544 (6th
    Cir. 2008). If he does not meet this burden, the defendant lacks standing for his
    challenge. 
    Id. A legitimate
    expectation of privacy exists when a defendant, “by his
    conduct, has exhibited an actual (subjective) expectation of privacy”—that is, has sought
    “to preserve something as private”—and when his “subjective expectation of privacy is
    one that society is prepared to recognize as reasonable.” Smith v. Maryland, 
    442 U.S. 735
    , 740 (1979) (internal quotation marks and brackets omitted).
    Nos. 12-6256/6354        United States v. Mathis, et al.                           Page 7
    A defendant may exhibit a subjective (though not necessarily legitimate)
    expectation of privacy when, for example, he places trash in an opaque garbage bag and
    sets it on the street for the garbage collector to take to the dump, see California v.
    Greenwood, 
    486 U.S. 35
    , 39 (1988); maintains “elaborate security around the perimeter
    of [a] complex barring ground-level public views of these areas,” Dow Chem. Co. v.
    United States, 
    476 U.S. 227
    , 229 (1986); erects a ten-foot fence to conceal his yard from
    street-level views, California v. Ciraolo, 
    476 U.S. 207
    , 211 (1986); closes himself in a
    phone booth to place a call, Katz v. United States, 
    389 U.S. 347
    , 352 (1967); stows a
    zipped luggage bag in the bedroom closet of an apartment at which he was temporarily
    staying, United States v. Waller, 
    426 F.3d 838
    , 844 (6th Cir. 2005); or hides cocaine in
    a shoe box in the basement rafters of the duplex in which he lived, United States v. King,
    
    227 F.3d 732
    , 754 (6th Cir. 2000) (Cole, J., concurring). Key to these cases is that the
    defendant showed, not merely by his statements during litigation, but by his conduct,
    that he sought to preserve something as private.
    A defendant’s expectation of privacy in an open field, however, is not recognized
    by society as reasonable. Oliver v. United States, 
    466 U.S. 170
    , 179 (1984). In other
    words, “no expectation of privacy legitimately attaches to open fields.” 
    Id. at 180.
    What
    qualifies as an open field, however, is less clear. The Supreme Court has instructed that
    an open field “need be neither ‘open’ nor a ‘field’ as those terms are used in common
    speech.” 
    Id. at 180
    n.11. The term includes “any unoccupied or undeveloped area
    outside of the curtilage.” 
    Id. Curtilage is
    “the area around the home to which the
    activity of home life extends,” 
    id. at 182
    n.12, and while business premises too enjoy
    Fourth Amendment protections, see See v. City of Seattle, 
    387 U.S. 541
    , 543 (1967), we
    have not decided whether there is such a thing as “business curtilage.” In Dow
    Chemical, the Supreme Court found an industrial plant complex with numerous plant
    structures spread over 2,000 acres to fall between open fields and curtilage, “but lacking
    some of the critical characteristics of 
    both.” 476 U.S. at 236
    . The Court ultimately held
    that the areas “are not analogous to the ‘curtilage’ of a dwelling for purposes of aerial
    surveillance.” 
    Id. at 239.
    More recently, this court noted that “[t]here may be
    circumstances in which the area adjoining a business structure is sufficiently private to
    Nos. 12-6256/6354        United States v. Mathis, et al.                             Page 8
    enjoy a protection analogous to a home’s curtilage,” but “it is clear that areas that adjoin
    a commercial building but are accessible to the public do not receive curtilage-like
    protection.” United States v. Elkins, 
    300 F.3d 638
    , 653, 654 (6th Cir. 2002). In Elkins,
    police officers walked down a path next to a commercial building and peered through
    an opening in the building to see marijuana plants inside. 
    Id. at 654.
    Despite a no
    trespassing sign on the building, we found the area on which the officers stood to be an
    “open field” because it was accessible to the public. 
    Id. United States
    v. Rapanos is also instructive. There the defendant, claiming a
    Fourth Amendment right to do so, barred state environmental inspectors from entering
    his 175-acre property to assess it for the presence of wetlands. 
    115 F.3d 367
    , 369 (6th
    Cir. 1997). The court held that the following factors had no bearing on whether the
    property was an open field: that the property was surrounded by a fence and a tall
    hedgerow of cleared debris, that entry onto the land could be made only through a locked
    gate, that the land had undergone “extensive alteration and development for one
    economic purpose or another and was clearly ‘commercial property,’” and that the
    landowner was present. 
    Id. at 373.
    Indeed, the “rather typical presence of fences, closed
    or locked gates, and ‘No Trespassing’ signs on an otherwise open field . . . has no
    constitutional import.” 
    Id. at 372;
    see also 
    Oliver, 466 U.S. at 182
    n.13 (“Certainly the
    Framers did not intend that the Fourth Amendment should shelter criminal activity
    wherever persons with criminal intent choose to erect barriers and post ‘No Trespassing’
    signs.”). We found that Dow Chemical undermined entirely the contention that the open
    fields doctrine could not apply to land that has been developed or prepared for
    development. 
    Rapanos, 115 F.3d at 373
    . “Nor is the government’s intrusion upon an
    open field a ‘search’ in the constitutional sense because that intrusion is a trespass at
    common law. The existence of a property right is but one element in determining
    whether expectations of privacy are legitimate.” 
    Oliver, 466 U.S. at 183
    ; see also Air
    Pollution Variance Bd. of Colo. v. W. Alfalfa Corp., 
    416 U.S. 861
    , 865 (1974) (finding
    a state health inspector “well within the ‘open fields’ exception,” whether he was “within
    or without the premises,” when he stood about two smokestack heights away from the
    base of the stack to inspect its smoke). Underpinning the analysis of these cases is the
    Nos. 12-6256/6354        United States v. Mathis, et al.                           Page 9
    Supreme Court’s command in Katz: “What a person knowingly exposes to the public,
    even in his own home or office, is not a subject of Fourth Amendment 
    protection.” 389 U.S. at 351
    .
    The searches in this case did not violate the Fourth Amendment because Fillers
    has not shown that he had a legitimate expectation of privacy in the property. First, the
    magistrate judge correctly concluded that Fillers had not exhibited a subjective
    expectation of privacy. Fillers claims an interest in keeping possession of the demolition
    materials and excluding others from the site, but his actions undermine this contention.
    Fillers did not post any signs, erect a fence or other barrier, hire a security guard, or
    monitor the site to exclude others. On at least one side of the property, anyone could
    simply step from the sidewalk onto the site as he or she pleased. And indeed, members
    of the public walked across the site and picked through the debris. There was no
    evidence of ongoing business, and the only building on the property was partially
    demolished and unused. Fillers’s argument that the site’s demolition nature alone
    evidences his subjective expectation of privacy is unavailing. As the magistrate judge
    found, “[t]he evidence presented at the evidentiary hearing on defendants’ motions to
    suppress is unequivocal that defendants took no actions whatsoever to maintain their
    privacy in the Watkins Street Property.” The record fully supports this statement; Fillers
    did not try to keep the property private. Accordingly, Fillers has not met his burden of
    establishing a subjective expectation of privacy.
    Second, even if Fillers had a subjective expectation of privacy, that expectation
    was unreasonable. The site qualifies as an open field. Though typically found in more
    rural areas, an open field need not be a “field.” See 
    Oliver, 466 U.S. at 180
    n.11. On the
    date of the search, the site was unoccupied and undeveloped (as one might reasonably
    understand “undeveloped” in an urban setting), consisting of a partially demolished
    building and debris strewn throughout a paved lot. See 
    id. (noting that
    the term “open
    field” includes “any unoccupied or undeveloped area outside of the curtilage”). As in
    Dow Chemical and Elkins, the property here is not sufficiently private to enjoy
    protection analogous to a dwelling’s curtilage. See Dow 
    Chemical, 476 U.S. at 236
    , 239;
    Nos. 12-6256/6354           United States v. Mathis, et al.                       Page 10
    
    Elkins, 300 F.3d at 653
    , 654. Rather, it is easily accessible to the public. And Rapanos
    teaches that the property’s commercial status has no bearing on whether the property is
    an open field, despite Fillers’s claim to the contrary. 
    Rapanos, 115 F.3d at 373
    . The
    lower court did not err in finding the site an open field.
    Futhermore, even if the property is not squarely an open field, any subjective
    expectation of privacy in it by Fillers would still be unreasonable. As the Supreme Court
    has held, the government has “greater latitude to conduct warrantless inspections of
    commercial property” because “the expectation of privacy that the owner of commercial
    property enjoys in such property differs significantly from the sanctity accorded an
    individual’s home.” Donovan v. Dewey, 
    452 U.S. 594
    , 598–99 (1981). And most
    importantly, Fillers knowingly exposed the entire site to public access by not doing
    anything to exclude the public. See 
    Katz, 389 U.S. at 351
    . Allinder v. Ohio, 
    808 F.2d 1180
    (6th Cir. 1987), offered by Fillers without much analysis, does not counsel
    differently. See 
    id. at 1185
    (noting that no case to date had used the open fields doctrine
    to justify “a search of personal effects or of a commercial structure in a field”). The
    property here was undeserving of Fourth Amendment protection; Fillers’s objection to
    the warrantless searches therefore fails.
    2.      Warrantless Seizures
    Warrantless seizures presumptively violate the Fourth Amendment, but under
    certain circumstances an officer may seize evidence in plain view without a warrant.
    Arizona v. Hicks, 
    480 U.S. 321
    , 326–27 (1987). Four factors must be satisfied: (1) the
    item seized must be in plain view, (2) the item’s incriminating character must be
    immediately apparent, (3) the officer must lawfully be in the place from where the item
    can be plainly seen, and (4) the officer must have a lawful right of access to the item.
    
    Horton, 496 U.S. at 136
    –37. Because the magistrate judge and district court did not
    clearly err in finding that the seized pipe-wrap samples were lying on the site in plain
    view, and because Fillers had no legitimate expectation of privacy in the 
    site, supra
    ,
    Fillers is unable to convincingly challenge the first, third, and fourth prongs of the
    warrantless seizure test.
    Nos. 12-6256/6354        United States v. Mathis, et al.                           Page 11
    We consider four other factors, none necessary but each instructive, to assess the
    “immediately apparent” prong: (1) the nexus between the seized item and the items
    particularized in the warrant, (2) whether the intrinsic nature or appearance of the item
    gives probable cause to believe it is associated with criminal activity, (3) whether the
    officers, at the time of discovery of the item and with the facts then available, can
    determine probable cause of the item’s incriminating nature, and (4) whether the officer
    can recognize the incriminating nature of the item as the result of his instantaneous
    sensory perception. 
    Garcia, 496 F.3d at 510
    –11. We have held that “when an item
    appears suspicious to an officer but further investigation is required to establish probable
    cause as to its association with criminal activity, the item is not immediately
    incriminating.” United States v. McLevain, 
    310 F.3d 434
    , 443 (6th Cir. 2002) (internal
    quotation marks omitted). But probable cause does not require knowledge that evidence
    is contraband. 
    Id. at 441.
    Instead, “probable cause is a flexible, common-sense
    standard. It merely requires that the facts available to the officer would warrant a man
    of reasonable caution in the belief that certain items may be contraband or stolen
    property or useful as evidence of a crime; it does not demand any showing that such a
    belief be correct or more likely true than false.” Texas v. Brown, 
    460 U.S. 730
    , 742
    (1983) (internal citations and quotation marks omitted). In making the probable cause
    determination, we look at the collective knowledge of the government agents. United
    States v. Poulos, 
    895 F.2d 1113
    , 1122 (6th Cir. 1990), abrogated on other grounds by
    Horton v. California, 
    496 U.S. 128
    (1990). Moreover, that an officer’s initial impression
    was reinforced by subsequent investigation does not undermine the initial existence of
    probable cause. See United States v. Rodriguez, 
    596 F.2d 169
    , 171, 175 (6th Cir. 1979)
    (subsequent chemical testing for heroin); United States v. Byrd, 
    211 F.3d 1270
    , at *3
    (6th Cir. 2000) (unpublished table opinion) (subsequent confirmation that child in
    pornographic pictures was underage).
    As the magistrate judge explained, John Schultz and Kathy Jones, the Bureau
    employees, had probable cause to believe that Fillers had not properly contained the
    asbestos when the buildings were demolished. Both Schultz and Jones were trained to
    identify suspected asbestos-containing materials, and both knew that old
    Nos. 12-6256/6354             United States v. Mathis, et al.                                    Page 12
    buildings—such as the partially demolished one remaining on the property—typically
    have asbestos wrap on pipes. Schultz and Jones saw pipe wrap material they recognized
    as likely to contain asbestos. And because Fillers and his company had applied to the
    Bureau for an asbestos removal permit, Schultz and Jones knew that the buildings on the
    property contained asbestos in the pipe wrap. In other words, the Bureau employees
    could immediately recognize the incriminating nature of the seized pipe-wrap samples,
    and they had probable cause to believe the items were associated with criminal activity.
    Further investigation later confirmed their beliefs, but probable cause was present before
    the seizure. See 
    Rodriguez, 596 F.2d at 171
    , 175. Accordingly, the plain view doctrine
    permitted Schultz and Jones to seize the pipe-wrap samples without a warrant. Fillers’s
    argument that the government may not use the open fields doctrine to justify the seizure
    of property is misplaced, since the seizure is justified by the plain view doctrine.
    We affirm the district court’s denial of Fillers’s motion to suppress.
    B.         Trial Testimony on Alleged Health Effects and Daycare Facility
    Fillers challenges testimony about asbestos’s negative health effects, and both
    Mathis and Fillers challenge testimony revealing the presence of a daycare facility near
    the site.
    1.       Alleged Health Effects Testimony
    Fillers contends that evidence of asbestos’s negative health effects should have
    been excluded as irrelevant and unfairly prejudicial under Federal Rules of Evidence 402
    and 403. He challenges statements made by three of the government’s twenty-three
    witnesses. See Test. Pamela McIlvaine1; Test. Richard Jardine2; Test. Peggy Jean
    1
    Q: Are you familiar with a term called air sampling? What is that?
    A: At a lot of work sites they set up air sampling. In a lot of ways that mitigates concerns of the
    public, if they can show that air levels are at a certain level. Under the asbestos NESHAP, the
    sampling that they talk about for the thorough sample inspection is bulk sampling, it’s not air
    sampling. There’s not a safe level of asbestos exposure that’s been established. So there’s no
    provisions under the asbestos NESHAP that says if you have air sampling that shows asbestos
    in the air below a certain level that that’s okay. There isn’t a safe level.

    Forney.3 Fillers did not object when this testimony was introduced, so we review its
    admission for plain error. United States v. Kelly, 
    204 F.3d 652
    , 655 (6th Cir. 2000).
    It was not plain error for the district court to permit these passing comments.
    First, the statements arguably were relevant. McIlvaine’s and Jardine’s testimony helped
    the jury understand part of the purpose of the asbestos regulations and work-practice
    standards, and Forney’s testimony helped establish her credibility as the expert chemist
    who confirmed that the samples contained asbestos. Second, the statements were not
    unfairly prejudicial, given the likelihood that the jurors already knew that asbestos is
    dangerous. And regardless, the district court was not clearly required to find that any
    such danger of unfair prejudice substantially outweighed the probative value of this
    testimony. Finally, any error in permitting this evidence was harmless because Fillers
    has not shown that this testimony, in light of the other evidence, had a substantial or
    Q: Please explain to the jury what asbestos is, generally.
    A: Asbestos is a naturally occurring mineral, and the microscopic fibers are very, very small,
    much smaller than a hair. You cannot see an individual fiber. And the reason that asbestos fibers
    pose health concerns is, they’re so small, and they’re very long compared to how wide they are,
    so the filtering mechanisms of your nose and your mouth won't filter out asbestos particles like
    it will filter out general -- other dust and particulate particles. So these particles will get past your
    nose and your mouth, and they’ll penetrate into your alveolae of your lungs, where the
    microphages in your system can’t get rid of them. They will try to absorb them, and actually
    form scar tissue around those fibers. And asbestosis -- I mean, asbestos exposure has been
    associated with asbestosis, lung cancer, and mesothelioma.
    2
    Q: With regard to -- You mentioned the asbestos worker training course. What did you learn
    in that course in your training?
    A: Well, we learned a number of things, specifically how to go about doing an asbestos
    abatement. There are specific techniques that you’re supposed to employ when you do that. Also
    we learned the hazards associated with asbestos, how it actually -- a single fiber can enter the
    alveola and very fine reaches of your lung air passageway, and it causes severe irritation and
    quite a lot of distress. It can ultimately -- as one of my friends contracted mesothelioma, it can
    cause death.
    3
    Q: How does a fume hood work?
    A: It’s -- a fume hood is a box that is in front of me. There’s a filter in the back. The airflow
    comes in front of my face, across the microscopes, and into the filter, so that I am protecting
    myself, any fibers go back into the filter instead of front, towards me.
    Q: And why are those precautions taken?
    A: I do not want to breathe asbestos fibers. I would like to live to an old age without health
    problems.

    injurious effect or influence on the jury’s verdict. See Fry v. Pliler, 
    551 U.S. 112
    , 116
    (2007).
    2.      Daycare Facility Testimony
    Both Mathis and Fillers argue that the district court erred when it denied their
    motion at trial to exclude testimony revealing the presence of a daycare center next to
    the site. They challenge the testimony of Bettye Spratling, who worked at the center, as
    irrelevant, unfairly prejudicial, and needlessly cumulative. We review the district court’s
    evidentiary ruling for an abuse of discretion. United States v. Blackwell, 
    459 F.3d 739
    ,
    752 (6th Cir. 2006).
    The district court did not abuse its discretion when it permitted Spratling to
    testify that she worked at a daycare facility next to the site, saw men throwing materials
    into the back of a truck, and had to bring the center’s children inside because of dust
    from the demolition activities. At trial, Fillers’s counsel conceded that Spratling’s
    observations would be relevant. That Spratling worked at the daycare center was
    arguably relevant to the jury’s understanding of the location from which she made her
    observations and her response to the dust. Moreover, the jury had already heard about
    the existence of the daycare center and the dust—in testimony Mathis and Fillers did not
    challenge—rendering Spratling’s testimony on the same not unfairly prejudicial.
    Finally, Spratling’s testimony was not needlessly cumulative because it reinforced and
    corroborated the testimony of other witnesses regarding the dust and handling of
    asbestos at the site. See Stapleton v. Wolfe, 
    288 F.3d 863
    , 868 (6th Cir. 2002). We do
    not hold a “definite and firm conviction” that the district court committed a clear error
    of judgment when it weighed the relevant factors and admitted Spratling’s testimony.
    See United States v. Schreane, 
    331 F.3d 548
    , 564 (6th Cir. 2003). And, like the alleged
    health effects testimony, any error in permitting this evidence was harmless. See 
    Fry, 551 U.S. at 116
    .
    We therefore affirm the district court’s admission of the health effects and
    daycare facility testimony.
    Nos. 12-6256/6354        United States v. Mathis, et al.                         Page 15
    C.      Sufficient Evidence for Convictions
    Both Mathis and Fillers challenge the sufficiency of the evidence supporting all
    counts of their convictions. We review sufficiency of the evidence challenges de novo
    to determine “whether, after viewing the evidence in the light most favorable to the
    prosecution, any rational trier of fact could have found the essential elements of the
    crime beyond a reasonable doubt.” Jackson v. Virginia, 
    443 U.S. 307
    , 319 (1979). We
    review the denial of a Rule 29 motion based on sufficiency of the evidence under the
    same standard. See United States v. Clay, 
    667 F.3d 689
    , 693 (6th Cir. 2012). “In
    making this determination, however, we may not reweigh the evidence, reevaluate the
    credibility of witnesses, or substitute our judgment for that of the jury.” United States
    v. Martinez, 
    430 F.3d 317
    , 330 (6th Cir. 2005).
    1.      Mathis
    Conspiracy. The jury convicted Mathis of conspiracy, in violation of 18 U.S.C.
    § 371. To establish conspiracy, the government must prove the existence of an
    agreement to act together in committing an offense and an overt act in furtherance of the
    conspiracy. United States v. Milligan, 
    17 F.3d 177
    , 182 (6th Cir. 1994). The agreement
    may be tacit, rather than explicit, and it may be inferred from circumstantial evidence.
    United States v. Deitz, 
    577 F.3d 672
    , 677 (6th Cir. 2009). “A defendant may be guilty
    of conspiracy despite possessing limited knowledge of the conspiracy’s scope, details
    and membership,” though he must know the purpose of the conspiracy. 
    Milligan, 17 F.3d at 183
    .
    Mathis’s conviction rested on two theories. First, the government alleged that
    Mathis conspired to defraud the United States by agreeing with Fillers to file the false
    10-day notice, which vastly understated the amount of asbestos at the site. Mathis acted
    in furtherance of the conspiracy, the government claimed, by actually filing the notice
    with estimates Mathis knew were false. Second, the government alleged that Mathis
    conspired with Fillers and others to violate the Clean Air Act, acting in furtherance of
    the conspiracy by directing his workers to start demolition before all asbestos had been
    safely removed.
    Nos. 12-6256/6354          United States v. Mathis, et al.                             Page 16
    Sufficient evidence ultimately supports both theories. In response to the first,
    Mathis contends that he used the Alternative Actions survey to complete other parts of
    the 10-day notice but left the asbestos estimate entry blank, and that Fillers or Herbert
    Warden later provided the incorrect numbers to Jones. The government’s brief counters
    that Jones testified that Mathis gave her the false estimates and “remained convinced”
    of this fact on cross-examination, but this characterization of Jones’s testimony is
    inaccurate. As the government conceded at oral argument, Jones was never positive that
    Mathis gave her the false estimates. Most damning to the government’s case, Jones
    stated on cross examination that “what I’ve tried to say all morning . . . is that I am not
    sure who gave me those first set of numbers . . . .” Thus, a rational juror could not rely
    on Jones’s testimony to prove beyond a reasonable doubt that Mathis gave her the false
    estimates.
    Nevertheless, the jury had sufficient circumstantial evidence to conclude that
    Mathis either provided or purposely omitted the numbers, thus implicating him in the
    conspiracy. Mathis admitted that he signed the notice, certifying that the information
    provided was “true and complete” to the best of his knowledge. He told an EPA
    criminal investigator that he used the Alternative Actions survey, which contained the
    amounts and locations of asbestos at the entire site, “to assist him in completing” the
    notice. Moreover, a juror could use Mathis’s later statements and actions, discussed
    below, as further evidence that he agreed to mislead the government with the notice.
    And though the indictment specifically charged Mathis with providing the false numbers
    to Jones, any variance resulting from reliance on this omission theory did not affect a
    substantial right of Mathis. See United States v. Beasley, 
    583 F.3d 384
    , 392 (6th Cir.
    2009) (“[S]ubstantial rights of the defendant are affected only when the defendant shows
    prejudice to his ability to defend himself at trial, to the general fairness of the trial, or to
    the indictment’s sufficiency to bar subsequent prosecutions.” (internal quotation marks
    omitted)). A rational juror could infer beyond a reasonable doubt that Mathis, in an
    attempt to mislead the government, either deliberately falsified the numbers in the notice
    or deliberately left that section of the form blank.
    Nos. 12-6256/6354        United States v. Mathis, et al.                         Page 17
    In response to the second theory, Mathis claims that he did not conspire to violate
    the Clean Air Act because he believed ADC had removed all of the asbestos at the site,
    and that it was safe to begin demolition. At trial, however, Warden testified that he
    repeatedly told Mathis that there was asbestos “all over the ground” during the period
    Mathis’s workers were demolishing the plant. Mathis did not alert the Bureau to this
    fact or delay demolition. From this testimony, a rational juror could have found that
    Mathis agreed with Fillers, albeit perhaps reluctantly, to oversee a demolition process
    that violated the EPA’s asbestos-removal regulations. Mathis’s conspiracy conviction
    thus must stand.
    Clean Air Act Violations. Mathis challenges his convictions under 42 U.S.C.
    § 7413(c)(1), which criminalizes the knowing violation of the EPA’s work-practice
    standards. The jury convicted Mathis of failing to file an accurate 10-day notice and of
    starting demolition before all asbestos had been removed. See 40 C.F.R. § 61.145(b),
    (c)(1). As discussed above, sufficient evidence exists to support Mathis’s conviction for
    failing to file an accurate notice. The jury also had ample evidence to conclude that
    Mathis knowingly violated the removal requirement. For example, Warden testified that
    he told Mathis about asbestos-containing materials scattered throughout the property that
    ADC was not hired to abate. Mathis replied that he “was tired of arguing with [Fillers],
    that [Fillers] was not paying for no more asbestos removal.” A rational juror could infer
    that Mathis knew asbestos was present when he began demolition. Accordingly this
    conviction must also stand.
    Rule 29 Arguments. Mathis separately challenges the district court’s denial of
    his motion for a judgment of acquittal under Federal Rule of Criminal Procedure 29,
    arguing that sufficient evidence did not support the conspiracy count. We review the
    denial of a Rule 29 motion based on sufficiency of the evidence under the same standard
    we apply to a challenge to the sufficiency of the evidence on appeal. See 
    Clay, 667 F.3d at 693
    . Thus, for the reasons described above, the district court did not err in denying
    Mathis’s Rule 29 motion.
    Nos. 12-6256/6354          United States v. Mathis, et al.                        Page 18
    Mathis also argues that the district court improperly took his Rule 29 motion
    under advisement when he first presented it at the close of the government’s case. But
    Federal Rule of Criminal Procedure 29(b) expressly allows a district court to “reserve
    decision” on a Rule 29 motion “where the motion is made before the close of all the
    evidence”—precisely what the district court did here. Mathis’s Rule 29 arguments are
    therefore without merit.
    Accordingly, we find that sufficient evidence supports all of Mathis’s
    convictions.
    2.      Fillers
    Conspiracy. Like Mathis, Fillers was convicted of conspiracy. Fillers argues
    that there was insufficient evidence that a conspiracy existed and that he knowingly
    joined it. Moreover, he contends, the district court erred by relying on his demolition
    contract with Mathis as sufficient proof of an agreement to violate the law. Fillers also
    claims that he was unaware of any Clean Air Act work-practice violations and that
    Halbert Warden’s testimony implicating him should be rejected because it contradicted
    Jones’s testimony.
    Fillers’s arguments are unavailing. First, ample evidence exists, beyond his
    contract with Mathis, that Fillers knowingly acted with others to unlawfully remove
    asbestos from the site. At trial Fillers’s brother Gary testified that Fillers was the head
    of Watkins Street Project. Warden, the abatement company manager, testified that Gary
    told him Fillers “wanted no more asbestos taken out” and that Mathis told him Fillers
    “was not paying for no more asbestos removal.” When Warden complained to Fillers
    that others were improperly removing asbestos-containing material, Fillers told him “it
    was none of [his] business.” And Fillers removed asbestos warning signs, telling
    Warden “it was drawing attention and he did not want these up.” Second, the
    government need not prove that Fillers knew he was violating the Clean Air Act, just
    that he knew the materials contained asbestos and that his actions released asbestos into
    the environment. See United States v. Buckley, 
    934 F.2d 84
    , 88 (6th Cir. 1991). The
    government produced sufficient evidence to support these points. Finally, that Warden’s
    Nos. 12-6256/6354          United States v. Mathis, et al.                        Page 19
    testimony was inconsistent with Jones’s testimony on a few issues—none essential to
    the government’s case—did not require the jury to reject either Warden’s or Jones’s
    testimony in whole. See United States v. Bazazpour, 
    690 F.3d 796
    , 803 (6th Cir. 2012)
    (“[A] jury may properly accept or reject testimony in whole or in part.” (internal
    quotation marks omitted)). A rational juror could have inferred beyond a reasonable
    doubt the existence of a conspiracy, which Fillers willingly joined, to remove asbestos
    from the site illegally.
    Clean Air Act Violations. The jury convicted Fillers of failing to file an accurate
    10-day notice, starting demolition before all asbestos had been removed, failing to have
    present during demolition an individual trained in the work-practice standards, and
    mishandling asbestos in various ways. See 40 C.F.R. §§ 61.145(b) (notice requirement),
    (c)(1) (removal requirement), (c)(2)–(6) (wetting and lowering requirements), (c)(8)
    (trained individual requirement), 61.150 (disposal requirements).
    Ample evidence exists again to support Fillers’s convictions. First, for reasons
    discussed below, a rational juror could have found that Fillers knew the 10-day notice
    contained a false estimate of asbestos. Second, there was substantial evidence to infer
    that Fillers knew unabated asbestos remained on the site after demolition began. Fillers
    possessed a copy of the Alternative Actions survey, which showed that the site contained
    a substantially higher amount of asbestos than the amount ADC was hired to abate. And
    Warden testified that Fillers hired him to abate only the asbestos in the boiler room and
    around two additional pipes, despite Warden’s telling Fillers that other asbestos existed
    outside of the boiler room. Third, Warden was not present when the other asbestos
    material was removed, and Fillers has not argued that any other trained individual was
    present during this removal. Finally, a number of witnesses testified that workers on the
    site did not properly wet or otherwise handle asbestos materials. Fillers was at the site
    every day during the demolition; a rational juror could infer beyond a reasonable doubt
    that he knew of the improper handling. Simply put, sufficient evidence supported
    Fillers’s convictions on the substantive Clean Air Act counts.
    Nos. 12-6256/6354          United States v. Mathis, et al.                          Page 20
    False Statement. The jury also convicted Fillers of making a false statement, in
    violation of 18 U.S.C. § 1001(a)(2), when he gave an allegedly false asbestos estimate
    to Kathy Jones, the Bureau employee. Fillers’s primary challenge to this conviction is
    that he did not know the estimate, which was based on the limited ADC survey, was
    false. But circumstantial evidence indicates that Fillers knew the contents of the
    comprehensive Alternative Actions survey and, therefore, that using the ADC survey
    would greatly understate the amount of asbestos present on the site. Fillers was present
    at the initial walkthrough for the Alternative Actions survey. The survey was delivered
    to Fillers’s brother and business partner Gary, and the Watkins Street Project operating
    agreement required Fillers, as the company’s “chief manager,” to “supervise and direct
    generally all of the business affairs of the [c]ompany.” And depending on who was
    asking for it, Fillers provided the survey in whole, in part, or not at all, or denied its
    existence. From these facts, a rational juror could conclude beyond a reasonable doubt
    that Fillers knew the contents of the Alternative Actions survey, and thus that he made
    a false statement when he told Kathy Jones the site contained much less asbestos than
    estimated in the survey.
    Obstruction of Justice. Fillers challenges his conviction under 18 U.S.C. § 1519,
    which prohibits the knowing alteration, destruction, concealment, or falsification of any
    document with the intent to impede, obstruct, or influence a federal investigation or
    matter. The government alleged that Fillers obstructed justice when he knowingly gave
    Schultz an incomplete version of the Alternative Actions survey, from which he had
    removed several pages listing significant quantities of asbestos-containing material, to
    impede a potential investigation. Fillers contends that he did not know the version was
    missing pages and that, at any rate, Schultz’s investigation was not impeded.
    The evidence from trial is sufficient under the Jackson standard to sustain
    Fillers’s conviction on this count. Schultz’s copy of the Alternative Actions survey
    indicated that he had received it from Fillers. While Schultz initially testified that he had
    received all five pages of a spreadsheet contained in the survey, on cross and
    redirect—after reviewing his incident report—Schultz stated and remained convinced
    Nos. 12-6256/6354        United States v. Mathis, et al.                         Page 21
    that he did not receive two of the five spreadsheet pages from Fillers. Those pages
    contained locations and quantities of asbestos-containing materials on the site.
    Moreover, Fillers had provided incomplete copies of the survey, and even denied its
    existence, at other times. From these facts, a rational juror could find beyond a
    reasonable doubt that Fillers intended to provide an incomplete version of the survey in
    order to impede Schultz’s impending investigation.
    We therefore find that sufficient evidence supports all of Fillers’s convictions.
    D.      Sentencing Guidelines Range
    Mathis and Fillers challenge the district court’s application of two enhancements:
    a six-level adjustment under U.S.S.G. § 2Q1.2(b)(1)(A) for engaging in an “ongoing
    continuous, or repetitive discharge, release, or emission of a hazardous or toxic
    substance or pesticide into the environment,” and a nine-level adjustment under
    § 2Q1.2(b)(2) for conduct “result[ing] in a substantial likelihood of death or serious
    bodily injury.” We review the district court’s legal interpretation of the sentencing
    guidelines de novo and its factual conclusions for clear error. United States v. Poulsen,
    
    655 F.3d 492
    , 505 (6th Cir. 2011). A factual conclusion is clearly erroneous only if,
    “although there may be some evidence to support the finding, the reviewing court on the
    entire evidence is left with the definite and firm conviction that a mistake has been
    committed.” United States v. Darwich, 
    337 F.3d 645
    , 663 (6th Cir. 2003). The district
    court must find by a preponderance of the evidence that the enhancement applies.
    
    Poulsen, 655 F.3d at 505
    .
    1.      Ongoing, Continuous, or Repetitive Release of a Hazardous
    Substance
    Mathis and Fillers contest the district court’s application of U.S.S.G.
    § 2Q1.2(b)(1)(A). That guideline requires a six-level enhancement if “the offense
    resulted in an ongoing, continuous, or repetitive discharge, release, or emission of a
    hazardous or toxic substance . . . into the environment.” To trigger the provision, the
    government must show that some amount of hazardous or toxic substance contaminated

    the environment, but it need not show actual harm to the environment. See United States
    v. Bogas, 
    920 F.2d 363

    indicates that asbestos made its way outside of the containment area”). Moreover, we
    agree with the Ninth Circuit that direct evidence of a substance’s release into the
    environment is not necessary; rather, “in most cases reasonable inferences from available
    evidence will suffice to support a conclusion that illegal acts resulted in contamination.”
    United States v. Technic Servs., Inc., 
    314 F.3d 1031
    , 1047 (9th Cir. 2002), overruled on
    other grounds by United States v. Contreras, 
    593 F.3d 1135
    (9th Cir. 2010).
    Mathis and Fillers attack the district court’s factual conclusions, arguing that the
    evidence did not sufficiently show that asbestos was released into the environment. We
    disagree. The Alternative Actions survey indicated that the site contained far more
    asbestos than ADC was hired to abate. Multiple witnesses testified that they saw
    workers remove—or that they personally removed—material likely containing asbestos
    without wetting it, instead “dump[ing] it out of the back side of the building” and
    collecting it into trucks for removal. And materials lying on the ground at the site tested
    positive for asbestos after demolition had occurred. To support its findings, the district
    court did not rely on the mere presence of dust, which Mathis and Fillers claim was not
    shown to contain asbestos. Nor do the tests showing that the air did not contain
    asbestos—none conducted at the same time as the improper removal of
    asbestos—require us to reverse the district court’s findings. We are not left with the
    definite and firm conviction that the court made a mistake in concluding that asbestos
    had been released into the environment. Its factual findings were therefore not clearly
    erroneous, and its application of the § 2Q1.2(b)(1)(A) enhancement was proper.
    2.      Substantial Likelihood of Death or Serious Bodily Injury
    Mathis and Fillers also disagree with the district court’s application of U.S.S.G.
    § 2Q1.2(b)(2). That guideline requires a nine-level enhancement if “the offense resulted
    in a substantial likelihood of death or serious bodily injury.” The district court applied
    Nos. 12-6256/6354        United States v. Mathis, et al.                          Page 23
    this enhancement after hearing days of testimony and argument about the potential
    health effects of asbestos exposure on the site’s salvage and demolition workers, and it
    explained its application in a thorough memorandum. Mathis and Fillers contest the
    court’s legal and factual conclusions.
    Citing Lindstrom v. A-C Product Liability Trust, 
    424 F.3d 488
    (6th Cir. 2005),
    the defendants argue that a court should not apply § 2Q1.2(b)(2) unless it finds that
    someone suffered substantial exposure to a hazardous material for a substantial period
    of time. But Lindstrom—a products liability case—explained how a plaintiff could show
    that a product was a substantial factor in causing an injury, not how one could show that
    conduct caused a substantial likelihood of an injury. See 
    id. at 492.
    As the district court
    properly recognized, the two inquiries are distinct. Much more on point is United States
    v. Thorn, 
    317 F.3d 107
    (2d Cir. 2003), aff’d, 
    446 F.3d 378
    , 383 (2006). We agree with
    the Second Circuit’s reasoning: a district court should apply the § 2Q1.2(b)(2)
    enhancement if the defendant’s offense made it considerably more likely that a person
    would die or develop a serious bodily injury. See 
    id. at 117.
    Actual death or serious
    bodily injury need not occur to apply the enhancement. 
    Id. Moreover, the
    district court
    correctly found that a defendant’s conviction for violating a work-practice standard does
    not automatically trigger § 2Q1.2(b)(2), though such violations may be relevant to
    determining the likelihood of death or serious injury.
    Mathis and Fillers further contend that the district court clearly erred in finding
    that any exposure to asbestos, no matter how small, is unsafe. They also believe that the
    evidence did not sufficiently show that workers were even exposed to asbestos. But
    once again, the record does not leave us with the definite and firm conviction that the
    district court made a mistake in its findings of fact. The court found that “no exposure
    to asbestos is proven safe” and “any exposure to asbestos is potentially hazardous,” that
    “workers were necessarily exposed to asbestos fibers released by” their improper
    removal procedures, and that “members of the salvage crew were not only exposed to
    asbestos fibers, but inhaled them.” Evidence put forth at trial and the sentencing hearing
    supports each of these conclusions. Moreover, the court thoughtfully considered and
    Nos. 12-6256/6354        United States v. Mathis, et al.                          Page 24
    weighed the testimony from the parties’ experts, finding the government’s toxicologist
    more persuasive. Though Mathis and Fillers strongly dispute that expert’s conclusions,
    we see no clear error in the court’s assessment. See United States v. Yi, 
    704 F.3d 800
    ,
    806–07 (9th Cir. 2013) (finding no clear error where the district court “both considered
    and permissibly gave little or no weight to the defense expert’s opinion” regarding the
    potential harm of asbestos exposure).         The district court properly applied the
    § 2Q1.2(b)(2) enhancement.
    3.      Minimal or Minor Role, and Alleged Enhancement for Acting
    Without or in Violation of a Required Permit
    Mathis separately argues that he deserved a reduction in his guidelines range
    because he was a “minimal” or “minor participant in the criminal activity.” See U.S.S.G.
    § 3B1.2. A minimal participant is “plainly among the least culpable of those involved
    in the” criminal activity, and a minor participant is “less culpable than most other
    participants, but [one] whose role could not be described as minimal.” 
    Id. cmt. nn.
    4, 5.
    Mathis bore the burden of proving by a preponderance of the evidence that he was
    entitled to such a mitigating-role reduction. United States v. Salgado, 
    250 F.3d 438
    , 458
    (6th Cir. 2001). He did not meet that burden here. At the very least, Mathis directed day
    after day of demolition knowing the site still contained asbestos, and he signed the false
    10-day notice that misled the Bureau. It was not clearly erroneous for the district court
    to deny Mathis a mitigating-role reduction.
    Mathis raises a final challenge to his sentence by claiming that “the trial court
    appears to have applied” a 2-level enhancement under § 2Q1.2(b)(4) for the
    “transportation, treatment, storage, or disposal [of a hazardous substance] without a
    permit or in violation of a permit.” But the district court did not actually apply this
    enhancement. Mathis’s PSR recommended not applying the enhancement, and the
    government objected.      At sentencing, after argument on the subject, the court
    unequivocally denied the objection. Mathis does not argue that his sentence was
    improperly calculated or that the district court applied the enhancement despite its
    intention not to do so. This argument is therefore without merit.
    Nos. 12-6256/6354       United States v. Mathis, et al.                          Page 25
    III. CONCLUSION
    We affirm the district court’s denial of Fillers’s motion to suppress the asbestos-
    containing samples, the district court’s admission of the challenged health effects and
    daycare facility testimony, Fillers’s and Mathis’s convictions, and the district court’s
    sentencing decisions.
