    SUMMARY
    March 22, 2018
    2018COA40
    No. 17CA0051, Maralex Res., Inc. v. Colo. Oil & Gas
    Conservation Comm’n — Administrative Law — Oil and Gas
    Conservation Act — Colorado Oil and Gas Conservation
    Commission; Constitutional Law — Fourth Amendment —
    Searches and Seizures — Administrative Searches
    In this appeal of an administrative agency order, a division of
    the court of appeals considers whether the Colorado Oil and Gas
    Conservation Commission (COGCC) can constitutionally subject oil
    and gas locations to unannounced, warrantless inspections. The
    division concludes that a COGCC rule permitting warrantless
    inspections of oil and gas locations does not violate the United
    States or Colorado Constitution. Because it authorizes searches
    falling within the administrative search exception to the warrant
    requirement, the COGCC rule is constitutional. Further, the
    division concludes that the inspection of the oil and gas locations at
    issue here did not violate the surface owners’ constitutional rights.
    The division also considers COGCC’s findings that Maralex
    Resources, Inc., violated various agency rules at two oil and gas
    locations. The division concludes that one of COGCC’s findings was
    arbitrary and capricious in one respect, but otherwise affirms the
    district court’s order enforcing COGCC’s order.
    Accordingly, the division affirms in part, reverses in part, and
    remands with directions.

    VI, § 5(3), and § 24-51-1105, C.R.S. 2017.
    ¶1    In this appeal of an administrative agency decision, plaintiffs,
    Maralex Resources, Inc. (Maralex), A.M. O’Hare (O’Hare), and Mary
    C. O’Hare, appeal the district court’s order affirming an order
    finding violation (OFV) issued by defendant, the Colorado Oil and
    Gas Conservation Commission (COGCC). On appeal, Maralex and
    the O’Hares contend that a COGCC rule permitting random,
    warrantless searches of oil and gas properties violates the United
    States and Colorado Constitutions. As a matter of first impression,
    we conclude that the COGCC rule is constitutional because it
    permits searches falling within the administrative search exception
    to the warrant requirement. To the extent the O’Hares separately
    challenge the constitutionality of the rule, we similarly reject their
    challenge.
    ¶2    Maralex also appeals the district court’s order enforcing
    COGCC’s findings that it violated several rules at two of its oil and
    gas locations. Because we agree with Maralex that one of COGCC’s
    findings was arbitrary and capricious in one respect, we reverse the
    district court’s order in part and affirm in part.
    1
    I. Background
    A. Facts
    ¶3    In a prehearing statement submitted to the COGCC, the
    parties stipulated to the following facts.
    ¶4    O’Hare was the president of Maralex, a Colorado corporation
    licensed to conduct oil and gas operations in the state. Maralex
    operated over 200 oil wells in Colorado. As relevant here, Maralex
    was the operator of three producing wells in southwest Colorado —
    Katie Eileen 34-7-35 2A (Katie Eileen 2A), Katie Eileen 34-7-35 2
    (Katie Eileen 2), and Katie Eileen 34-7-35 3 (Katie Eileen 3).1 The
    wells were located on the O’Hares’ ranch, and the O’Hares owned
    both the surface and mineral rights, though they leased a mineral
    interest to Maralex beginning in 1995.
    ¶5    The wells were located on two separate oil and gas locations.2
    Katie Eileen 2A was located on a western location, while Katie
    Eileen 2 and 3 were located on an eastern location. The Katie
    1 A COGCC rule defines operator as “any person who exercises the
    right to control the conduct of oil and gas operations.” Dep’t of Nat.
    Res. Rule 100, 2 Code Colo. Regs. 404-1.
    2 A COGCC rule defines oil and gas location as “a definable area
    where an operator has disturbed or intends to disturb the land
    surface in order to locate an oil and gas facility.” 
    Id. 2 Eileen
    2 well was completed in 1996, and the Katie Eileen 3 well
    was completed in 2007.
    ¶6    Additionally, there were two pits on the eastern location
    adjacent to the Katie Eileen 2 and 3 wells.3 One pit was unlined,
    and the other had a partially torn liner. The O’Hares used those
    pits as stock ponds for their cattle.
    ¶7    In the afternoon of March 20, 2014, a COGCC field inspection
    supervisor contacted a local Maralex office and requested access to
    the Katie Eileen wells to conduct a routine inspection. Maralex
    employees informed the inspection supervisor that the properties
    were protected by locked gates and, because O’Hare was out of
    town, they could not permit access that day. The inspection
    supervisor agreed to delay the inspection for a day, provided that
    Maralex contact him “oil-field early” — meaning, according to
    industry custom, at 6:00 a.m. — the next day.
    ¶8    At 9:30 a.m. the following morning, not having heard from
    Maralex, the inspection supervisor issued a notice of alleged
    3A COGCC rule defines pit generally as “any natural or man-made
    depression in the ground used for oil or gas exploration or
    production purposes.” 
    Id. The rule
    also lists various types of pits.
    See 
    id. 3 violation
    based on Maralex’s failure to provide access to the wells.
    There was no communication between Maralex and the inspection
    supervisor until mid-morning, when O’Hare called the inspection
    supervisor.
    ¶9    The exact content of the March 21 phone call was disputed,
    but the conversation was apparently heated and arguably
    culminated in O’Hare threatening the inspection supervisor. O’Hare
    emailed the inspection supervisor later that day offering to allow the
    inspection supervisor access to the wells the following Monday
    morning. However, he also wrote that, had the inspection
    supervisor attempted to enter the property in spite of the locked
    gates, he would have been at risk of being shot because the
    O’Hares’ children had been instructed to shoot trespassers. O’Hare
    added:
    If your purpose is truly to inspect the locations
    for adherence to the COGCC rules and
    regulations then bring your notepad on
    Monday and you can write up all the
    deficiencies you find and we will address them
    to the best of our ability as soon as we can. If
    your intention is to run roughshod over our
    Constitutional rights then you should be
    prepared for a fight because I will defend my
    rights and my family to the death! Any
    questions?
    4
    ¶ 10   COGCC then sought an administrative search warrant
    authorizing entry to and inspection of the western and eastern
    locations, which was granted by the La Plata County District Court.
    On March 27, 2014, the COGCC executed that warrant.
    B. COGCC’s Inspections and Order
    ¶ 11   During the initial March 27 inspection, COGCC staff noted
    several rules violations, including, as relevant here, improperly
    stored equipment at the Katie Eileen 2A well and unclosed pits at
    the Katie Eileen 2 and 3 wells, one of which contained improperly
    stored drill cuttings.4
    ¶ 12   About two weeks later, COGCC staff conducted a follow-up
    inspection of the wells. That inspection revealed that the previously
    observed violations were ongoing. Additionally, a COGCC
    environmental protection specialist collected soil samples from the
    pits adjacent to the Katie Eileen 2 and 3 wells. Those soil samples
    showed levels of various contaminants that exceeded COGCC rules.
    4 Drill cuttings “are bits of rock and soil cut from subsurface
    formations by the drill bit during the process of drilling a well and
    then lifted to the surface by circulation of oil-based drilling fluids.”
    Osage Envtl., Inc. v. R.R. Comm’n, No. 03-08-00005-CV, 
    2008 WL 2852295
    , at *1 n.2 (Tex. App. July 24, 2008) (unpublished opinion).
    5
    ¶ 13   Based on the inspections of the Katie Eileen wells, COGCC
    issued Maralex multiple notices of alleged violations during June
    and August of 2014. Challenging these notices, Maralex requested
    an administrative hearing. COGCC held a hearing at which various
    COGCC and Maralex employees testified. Following the hearing,
    COGCC issued an OFV, concluding that Maralex had violated
    several rules, including, as relevant here, Rules 204, 603.f, 905(a),
    and 907(a)(1). See Dep’t of Nat. Res. Rule 204, 2 Code Colo. Regs.
    404-1; Dep’t of Nat. Res. Rule 603.f, 2 Code Colo. Regs. 404-1;
    Dep’t of Nat. Res. Rule 905(a), 2 Code Colo. Regs. 404-1; Dep’t of
    Nat. Res. Rule 907(a)(1), 2 Code Colo. Regs. 404-1. In total,
    Maralex was assessed a penalty of $94,000 for the violations.
    C. The District Court’s Order
    ¶ 14   Maralex and the O’Hares sought judicial review of COGCC’s
    order. They raised constitutional challenges to COGCC’s rule
    permitting warrantless inspections of oil and gas locations and
    sought injunctive and declaratory relief. The O’Hares (but not
    Maralex) raised a separate constitutional challenge to the inspection
    rule based on their status as surface owners. Maralex (but not the
    6
    O’Hares) also challenged COGCC’s determination of rules violations
    in the OFV.
    ¶ 15   In a thorough and well-reasoned order, the district court
    denied Maralex and the O’Hares declaratory and injunctive relief,
    concluding that COGCC’s inspection rule did not violate either the
    United States or Colorado Constitution. Similarly, the district court
    concluded that the O’Hares’ constitutional rights were not violated.
    The district court also affirmed the OFV in full, finding that all the
    violations were supported by competent evidence in the agency’s
    record.
    II. Constitutionality of Rule 204
    ¶ 16   Maralex and the O’Hares argue that COGCC “lacks statutory
    authority” to conduct unannounced, warrantless searches of oil and
    gas locations. Although they do not characterize it as such, we
    construe this claim as a facial challenge to the constitutionality of
    Rule 204, which permits authorized COGCC staff “the right at all
    reasonable times to go upon and inspect any oil or gas properties.”
    Dep’t of Nat. Res. Rule 204, 2 Code Colo. Regs. 404-1; see City of
    Los Angeles v. Patel, 576 U.S. ___, ___, 
    135 S. Ct. 2443
    , 2449 (2015)
    (“[F]acial challenges under the Fourth Amendment are not
    7
    categorically barred or especially disfavored.”). We conclude that
    Rule 204 passes constitutional muster.
    A. Standard of Review
    ¶ 17   Because it is a question of law, we review the constitutionality
    of an agency rule de novo. See Indep. Inst. v. Coffman, 
    209 P.3d 1130
    , 1135 (Colo. App. 2008).
    B. Administrative Searches
    ¶ 18   The Fourth Amendment protects “[t]he right of the people to be
    secure in their persons, houses, papers, and effects, against
    unreasonable searches and seizures.” U.S. Const. amend. IV.
    Likewise, the Colorado Constitution prohibits “unreasonable
    searches and seizures.” Colo. Const. art II, § 7. As a general rule, a
    warrantless search is presumptively unreasonable. Patel, 576 U.S.
    at ___, 135 S. Ct. at 2452. The Fourth Amendment’s prohibition on
    unreasonable searches and seizures is applicable to commercial
    premises. New York v. Burger, 
    482 U.S. 691
    , 699 (1987).
    ¶ 19   However, the Supreme Court has carved out certain
    exceptions to the requirement that searches be conducted pursuant
    to a warrant issued upon probable cause. One such exception is in
    the context of administrative searches. See Eddie’s Leaf Spring
    8
    Shop & Towing LLC v. Colo. Pub. Utils. Comm’n, 
    218 P.3d 326
    , 332
    (Colo. 2009). Developed in two Supreme Court cases, Colonnade
    Catering Corp. v. United States, 
    397 U.S. 72
    (1970), and United
    States v. Biswell, 
    406 U.S. 311
    (1972), this exception has been
    referred to as the Colonnade-Biswell exception. See, e.g., Exotic
    Coins, Inc. v. Beacom, 
    699 P.2d 930
    , 942 (Colo. 1985).
    ¶ 20   Under this exception, “a warrantless inspection made
    pursuant to a regulatory scheme of a closely regulated industry is
    reasonable if three requirements are met.” Eddie’s Leaf Spring
    
    Shop, 218 P.3d at 332
    . First, the regulatory scheme must “be
    informed by a substantial government interest.” 
    Id. Second, warrantless
    searches must be necessary to further that government
    interest. 
    Id. Third, the
    regulatory scheme must “provide a
    ‘constitutionally adequate substitute’ for a warrant in terms of the
    certainty and regularity of the program’s application.” 
    Id. (quoting Burger,
    482 U.S. at 700).
    ¶ 21   The Colonnade-Biswell exception is rooted in the principle
    that, because there is a reduced expectation of privacy on the part
    of an owner of commercial premises in a pervasively regulated
    industry, the traditional warrant and probable cause requirements
    9
    have lessened application. See Marshall v. Barlow’s, Inc., 
    436 U.S. 307
    , 313 (1978) (“[W]hen an entrepreneur embarks upon such a
    business, he has voluntarily chosen to subject himself to a full
    arsenal of governmental regulation.”).
    ¶ 22   The Supreme Court has stated that this exception to the
    warrant requirement is a narrow one. In a recent decision, the
    Court noted that it had applied the administrative search exception
    to only four closely regulated industries: “liquor sales, firearms
    dealing, mining, or running an automobile junkyard.” Patel, 576
    U.S. at ___, 135 S. Ct. at 2454 (citations omitted). In Patel, the
    Court held that the hotel industry was not “pervasively regulated”
    because it was subject only to “general regulations” like licensure,
    tax, rate postage, and sanitary requirements. Id. at ___, 135 S. Ct.
    at 2455 (noting that such regulations “hardly . . . put[] hotel owners
    on notice that their ‘property will be subject to periodic inspections
    undertaken for specific purposes’” (quoting 
    Burger, 482 U.S. at 705
    n.16)).
    ¶ 23   Despite the Court’s admonition that the closely regulated
    industry “is the exception,” 
    Marshall, 436 U.S. at 313
    , other courts
    have found that many and varied industries fall within that
    10
    exception. See Eddie’s Leaf Spring 
    Shop, 218 P.3d at 333
    (nonconsensual towing); Gora v. City of Ferndale, 
    576 N.W.2d 141
    ,
    147 (Mich. 1998) (massage parlors); State v. Klager, 
    797 N.W.2d 47
    ,
    53 (S.D. 2011) (taxidermy); Hill v. Commonwealth, 
    624 S.E.2d 666
    ,
    671-72 (Va. Ct. App. 2006) (food production).
    C. Analysis
    ¶ 24   Maralex and the O’Hares contend that COGCC lacks authority
    to conduct unannounced, warrantless searches of oil and gas
    locations. While they opaquely reference the analysis set forth in
    Supreme Court and Colorado cases discussing administrative
    searches, neither their opening brief nor their reply brief addresses
    COGCC’s contention that the Colonnade-Biswell exception applies
    here. We conclude that COGCC’s inspection scheme, as codified in
    Rule 204, does not violate the United States or Colorado
    Constitution.
    ¶ 25   We first address whether the oil and gas industry is “closely
    regulated.” Eddie’s Leaf Spring 
    Shop, 218 P.3d at 332
    . “The key
    factors in determining whether an industry is closely regulated are
    the pervasiveness and regularity of the regulation and the effect of
    such regulation upon an owner’s expectation of privacy.” 
    Id. 11 ¶
    26   We conclude that the oil and gas industry is closely regulated.
    The Oil and Gas Conservation Act (Act), §§ 34-60-101 to -130,
    C.R.S. 2017, provides COGCC with substantial authority to regulate
    oil and gas facilities. See generally Chase v. Colo. Oil & Gas
    Conservation Comm’n, 
    2012 COA 94M
    , ¶¶ 24-29, 
    284 P.3d 161
    ,
    165-67 (detailing COGCC’s history and authorizing legislation).
    Indeed, COGCC is empowered to “do whatever may reasonably be
    necessary to carry out the provisions of th[e Act].” § 34-60-105(1),
    C.R.S. 2017. To that end, COGCC has promulgated comprehensive
    rules regulating multitudinous aspects of the oil and gas industry.
    See City of Fort Collins v. Colo. Oil & Gas Ass’n, 
    2016 CO 28
    , ¶ 29,
    
    369 P.3d 568
    , 593 (characterizing COGCC’s rules as “exhaustive”
    and “comprehensive[]”); City of Longmont v. Colo. Oil & Gas Ass’n,
    
    2016 CO 29
    , ¶ 52, 
    369 P.3d 573
    , 584 (same). The inevitable effect
    of this exhaustive regulatory scheme is a lessened expectation of
    privacy in commercial premises for operators in Colorado’s oil and
    gas industry. See Eddie’s Leaf Spring 
    Shop, 218 P.3d at 332
    -33.
    ¶ 27   Moreover, courts in other jurisdictions have concluded that
    the oil and gas industry is closely regulated. See United States v.
    Stinson, No. 1:12CR-00012-JHM, 
    2013 WL 1221937
    , at *3 (W.D.
    12
    Ky. Mar. 25, 2013) (unpublished opinion) (oil and gas industry is
    “highly regulated”); Matter of Mullins & Pritchard, Inc., 
    549 So. 2d 872
    , 876-77 (La. Ct. App. 1989) (“[I]t is obvious that the oil and gas
    production facilities subject to the warrantless searches fall under
    the ‘pervasively regulated industry’ exception to the warrant
    requirement.”). We similarly conclude that the comprehensive
    scheme governing oil and gas operations in Colorado renders the
    industry closely regulated.
    ¶ 28      Next, we consider whether the three additional criteria
    necessary to make warrantless inspections reasonable are satisfied.
    First, we must determine whether the state has a substantial
    interest in regulating oil and gas operations. We conclude that it
    does.
    ¶ 29      According to the Act’s legislative declaration, it is “in the
    public interest” to “[f]oster the responsible, balanced development,
    production, and utilization of the natural resources of oil and gas in
    the state of Colorado in a manner consistent with protection of
    public health, safety, and welfare, including protection of the
    environment and wildlife resources.” § 34-60-102(1)(a)(I), C.R.S.
    2017. The Act “and the Commission’s pervasive rules and
    13
    regulations . . . convince us that the state’s interest in the efficient
    and responsible development of oil and gas resources includes a
    strong interest in the uniform regulation” of oil and gas operations.
    City of Fort Collins, ¶ 
    29, 369 P.3d at 593
    .
    ¶ 30   Second, we consider whether warrantless searches are
    necessary to further the state’s substantial interest in the safe and
    efficient operation of oil and gas facilities. We conclude that they
    are. Imposing a warrant (and, as a result, probable cause)
    requirement would frustrate COGCC’s ability to effectively enforce
    the Act by inspecting between 19,000 and 23,500 oil and gas
    facilities each year. See Oil & Gas Conservation Commission, Field
    Inspection Unit 1, https://perma.cc/9VR8-G59G. Requiring that
    inspectors apply to a court for a warrant before each inspection
    would dramatically reduce COGCC’s enforcement power, and might
    allow operators to conceal violations. Cf. Donovan v. Dewey, 
    452 U.S. 594
    , 603 (1981) (noting, in the context of the mining industry,
    the “notorious ease with which many safety or health hazards may
    be concealed if advance warning of inspection is obtained” (quoting
    S. Rep. No. 95-181, at 27 (1977))).
    14
    ¶ 31   To the extent Maralex and the O’Hares argue that the
    legislature must affirmatively declare that warrantless inspections
    are necessary to further a given agency’s regulatory interest, we find
    no authority for such a conclusion. In contrast, as COGCC points
    out, this position has been expressly rejected by other courts. See,
    e.g., Balelo v. Baldrige, 
    724 F.2d 753
    , 765 (9th Cir. 1984) (referring
    to a similar argument as a “novel constitutional proposition” and
    determining that “[t]he law is to the contrary”). Moreover, a 2013
    amendment to the Act instructed COGCC to begin conducting
    inspections pursuant to a “risk-based strategy” targeting “the
    operational phases that are most likely to experience spills, excess
    emissions, and other types of violations and that prioritizes more
    in-depth inspections.” § 34-60-106(15.5), (15.5)(b), C.R.S. 2017.
    That amendment was enacted prior to the inspections of the Katie
    Eileen wells here. In enacting that amendment, the legislature
    could have, but did not, impose any warrant requirement for
    COGCC inspections. In fact, the legislature specifically stated that
    the purpose of the legislative amendment was “to increase the
    frequency of inspections of oil and gas wells.” S. 13-202, 69th Gen.
    Assemb. § 1(c) (Colo. 2013).
    15
    ¶ 32   Last, we consider whether the occurrence of warrantless
    COGCC inspections was “so random, infrequent, or unpredictable
    that the owner, for all practical purposes, has no real expectation
    that his property will from time to time be inspected by government
    officials.” 
    Donovan, 452 U.S. at 599
    . In this case, neither party
    describes the frequency with which COGCC typically inspects any
    given location. However, a COGCC document states that “[o]n
    average, active wells are inspected once every 2.4 years.” See Field
    Inspection Unit at 1. Maralex and the O’Hares concede that the
    Katie Eileen 2 and 3 wells had been inspected four times between
    July 2000 and June 2006.
    ¶ 33   Further, as Maralex and the O’Hares acknowledge, Rule 204
    imposes a reasonableness requirement that circumscribes COGCC’s
    authority to conduct random inspections. We therefore conclude
    that COGCC’s inspection regime “provid[es] a constitutionally
    adequate substitute for a warrant.” 
    Burger, 482 U.S. at 703
    (quoting 
    Donovan, 452 U.S. at 603
    ).
    16
    ¶ 34   Because Rule 204 meets the Colonnade-Biswell criteria, we
    conclude that warrantless inspections made pursuant to the rule do
    not violate the Fourth Amendment.5
    ¶ 35   We reach the same outcome under the Colorado Constitution.
    Although article 2, section 7 of the Colorado Constitution has in
    some contexts been interpreted as providing broader privacy
    protections than its federal counterpart, Maralex and the O’Hares
    have not argued that any distinction between the two provisions is
    significant here. Cf. Eddie’s Leaf Spring 
    Shop, 218 P.3d at 334
    .
    “Additionally, our precedent provides no basis to distinguish
    between the rights under the [United States] and the Colorado
    Constitutions with regard to administrative searches.” 
    Id. 5Maralex and
    the O’Hares pointed us to separate litigation also
    concerning the Katie Eileen wells. Considering a challenge to the
    Bureau of Land Management’s (BLM’s) inspection scheme, a federal
    district court concluded that the BLM had statutory authority to
    conduct unannounced, warrantless searches under the Federal Oil
    and Gas Royalty Management Act of 1982, 30 U.S.C. § 1701 (2012).
    Maralex Res., Inc. v. Jewell, No. 15-cv-01893-CMA, 
    2017 WL 6033694
    (D. Colo. Oct. 19, 2017) (unpublished opinion) (order
    affirming agency determination).
    17
    ¶ 36   In sum, we conclude that Rule 204 does not run afoul of the
    United States or Colorado Constitution. The facial challenge to the
    inspection rule therefore fails.
    III. Other Constitutional Claims
    ¶ 37   The O’Hares also raise constitutional challenges to Rule 204 in
    their capacity as surface owners of land including oil and gas
    locations subject to COGCC oversight.
    ¶ 38   First, the O’Hares contend that Rule 204 is unconstitutional
    as applied to surface owners because, unlike the operators of oil
    and gas locations, they maintain an expectation of privacy in the
    property searched. However, in this case, the O’Hares granted
    Maralex an extraordinarily broad set of rights under the surface
    agreement. Specifically, the O’Hares gave Maralex “the right to do
    whatever they want on [their] property.” Under these
    circumstances, the O’Hares substantially lessened any objective
    expectation of privacy by granting the corporation an unlimited
    easement on the surface estate. Because we have already
    concluded that Rule 204 permitted COGCC’s inspection of
    Maralex’s operations, the O’Hares’ derivative claim must fail. We
    agree with the district court that, “[b]ecause Maralex has an
    18
    obligation to comply with [COGCC] orders, rules, and policies, the
    O’Hares do not have an expectation of privacy in property over
    which they willingly transferred access and control rights to
    Maralex.”
    ¶ 39    To the extent that the O’Hares challenge the application of
    Rule 204 to all surface owners, we must reject that facial challenge.
    We conclude that, in other cases where a surface owner has granted
    a mineral lessee a broad surface easement, warrantless entry of the
    surface estate would not necessarily violate the surface owner’s
    rights. See City & Cty. of Denver v. Casados, 
    862 P.2d 908
    , 913
    (Colo. 1993) (stating that a facial challenge is “the most difficult
    challenge to mount successfully, since the challenge must establish
    that no set of circumstances exists under which the [rule] would be
    valid”).
    ¶ 40    The O’Hares also purport to raise a takings claim under the
    Fifth Amendment. U.S. Const. amend. V (“[N]or shall private
    property be taken for public use, without just compensation.”). As
    they did in the district court, the O’Hares argue with extremely
    broad strokes that Rule 204 interferes with their property rights to
    such a degree as to constitute an uncompensated government
    19
    taking. Because this claim is set forth in a perfunctory manner, we
    decline to address it. See People v. Mershon, 
    874 P.2d 1025
    , 1034
    n.13 (Colo. 1994) (declining to address constitutional arguments
    that were only raised in a cursory fashion before the trial court); see
    also Wagner v. Georgetown Univ. Med. Ctr., 
    768 A.2d 546
    , 554 n.9
    (D.C. 2001) (“[I]ssues adverted to in a perfunctory manner,
    unaccompanied by some effort at developed argumentation, are
    deemed waived.” (quoting United States v. Zannino, 
    895 F.2d 1
    , 16
    (1st Cir. 1990))).
    IV. COGCC’s Order
    ¶ 41   Maralex also challenges the COGCC’s order concluding that it
    violated multiple rules in relation to the Katie Eileen wells. We
    reject its contentions, with one minor exception.
    ¶ 42   COGCC final orders are subject to judicial review in
    accordance with the State Administrative Procedure Act. § 34-60-
    111, C.R.S. 2017 (citing § 24-4-106, C.R.S. 2017). A “reviewing
    court may overturn an administrative agency’s determination only if
    the court finds the agency acted in an arbitrary and capricious
    manner, made a determination that is unsupported by the record,
    erroneously interpreted the law, or exceeded its constitutional or
    20
    statutory authority.” Sapp v. El Paso Cty. Dep’t of Human Servs.,
    
    181 P.3d 1179
    , 1182 (Colo. App. 2008) (citing § 24-4-106(7)). We
    defer to an agency’s findings of fact unless they are “unsupported
    by substantial evidence when the record is considered as a whole.”
    § 24-4-106(7).
    ¶ 43   We address each violation in turn.
    A. Rule 204
    ¶ 44   In its OFV, COGCC concluded that Maralex had violated Rule
    204 by denying the inspectors access for a period of seven days
    starting on March 20, 2014, the day the inspection supervisor first
    contacted Maralex. Maralex contends that COGCC erred for two
    reasons. First, it asserts no Rule 204 violation occurred on March
    20 because the inspection supervisor agreed to postpone the
    inspection until the next day after he was informed that O’Hare was
    unavailable. Second, Maralex contends there was no Rule 204
    violation from March 21 through March 27 because nothing
    effectively prevented COGCC staff from entering the property during
    that period.
    ¶ 45   We agree with the first of Maralex’s contentions. We conclude
    that COGCC’s finding that Maralex violated Rule 204 on March 20
    21
    was arbitrary and capricious. The undisputed facts in the record
    reflect that the inspection supervisor first contacted Maralex in the
    afternoon of March 20, and did not actually speak to an employee
    until nearly 4:00 p.m. that day. The inspection supervisor agreed
    to delay the inspection until the next day. Accordingly, we conclude
    there was not substantial evidence to support COGCC’s
    determination that Maralex failed to provide access to its wells at
    “all reasonable times.” See Dep’t of Nat. Res. Rule 204, 2 Code
    Colo. Regs. 404-1. Thus, we reverse the district court’s order
    affirming that part of the OFV concluding Maralex violated Rule 204
    on March 20, 2014. Accordingly, we also reverse the penalty
    assessed for the March 20 Rule 204 violations, which amounted to
    $2000.
    ¶ 46   However, we perceive no basis for disturbing COGCC’s
    conclusion that Maralex “effectively denied staff access through
    threats to staff’s safety” between March 21 — when O’Hare emailed
    the inspection supervisor stating that he had instructed his family
    to shoot trespassers — and March 27, when COGCC staff executed
    the search warrant. As COGCC noted in the OFV, the inspection
    supervisor testified that he was “quite terrified for his safety” and
    22
    felt threatened by O’Hare’s email and phone call. This evidence
    supports COGCC’s determination that Maralex violated Rule 204 for
    the duration of that six-day period.
    ¶ 47   Maralex attempts to minimize the impact of O’Hare’s email by
    characterizing it as stating “what any reasonable person should
    know — do not jump a locked gate and traverse across a private
    ranch in a rural area because you might be mistaken as a
    trespasser and if you are deemed a threat, you might get shot.”
    While O’Hare apparently believed he could legally shoot a person
    merely for entering his property without permission, his position is
    not supported by Colorado law.6
    ¶ 48   Thus, we affirm the district court’s enforcement of that part of
    the OFV concluding Maralex violated Rule 204 from March 21
    through March 27, 2014, including its imposition of $12,000 in
    fines for that period.
    6 Colorado statutes provide that a person may lawfully use physical
    force against another person in certain limited circumstances. See
    §§ 18-1-703 to -706, C.R.S. 2017. Further, a person may lawfully
    use deadly physical force against another person in limited
    circumstances. See § 18-1-704(2), C.R.S. 2017; § 18-1-704.5(2),
    C.R.S. 2017. However, nothing in those provisions authorizing use
    of physical force would have permitted O’Hare to legally shoot
    trespassers merely for entering his property without his permission.
    23
    B. Rule 603.f
    ¶ 49   Rule 603.f requires that oil and gas locations “be kept free of
    . . . [unnecessary] equipment, vehicles, and supplies” and “rubbish,
    and other waste material.” Dep’t of Nat. Res. Rule 603.f, 2 Code
    Colo. Regs. 404-1. The rule applies to “[a]ll locations, including
    wells.” 
    Id. COGCC concluded
    that Maralex had violated Rule 603.f
    at both Katie Eileen locations based on its finding that there was
    unnecessary equipment and debris at the locations. Maralex
    appeals only the violation arising from equipment and debris at the
    Katie Eileen 2A location.
    ¶ 50   Maralex argues, as it did before COGCC and in the district
    court, that the surface owners — the O’Hares — had reclaimed use
    of the relevant land and thus the area no longer constituted an “oil
    and gas location” within COGCC’s jurisdiction. Because the
    O’Hares had “exclusive possession and control” of the property,
    Maralex argues that it did not violate Rule 603.f.
    ¶ 51   We reject this argument. Referring to its definition of “oil and
    gas location” in Rule 100, COGCC determined that the location fell
    within its jurisdiction. Our review of the record leads us to the
    same result. See Colo. Citizens for Ethics in Gov’t v. Comm. for Am.
    24
    Dream, 
    187 P.3d 1207
    , 1219 (Colo. App. 2008) (“An agency’s
    determination of its own jurisdiction is reviewed de novo.”). The
    area on which the equipment and debris were observed is a
    “definable area where an operator has disturbed . . . the land
    surface in order to locate an oil and gas facility” — namely, the
    Katie Eileen 2A well. See Dep’t of Nat. Res. Rule 100, 2 Code Colo.
    Regs. 404-1. Especially in this context, where the O’Hares as
    surface owners granted Maralex an unchecked right of access to the
    surface estate, we conclude that Maralex violated Rule 603.f by
    failing to remove unnecessary equipment and debris from the area
    near the well.
    ¶ 52   Alternatively, Maralex asserts that the equipment belonged to
    O’Hare alone, and thus Maralex could not have violated the rule.
    However, as COGCC found, O’Hare’s testimony significantly
    undermined that argument. O’Hare contradictorily testified that he
    had purchased the equipment and that Maralex owned the
    equipment. As a result, COGCC found O’Hare not to be credible on
    this matter, and we defer to that finding. Similarly, we defer to
    COGCC’s finding that the equipment was Maralex’s.
    25
    ¶ 53   Accordingly, we affirm COGCC’s determination that Maralex
    violated Rule 603.f at the Katie Eileen 2A location.
    C. Rule 905(a)
    ¶ 54   Rule 905(a) states that “[d]rilling pits shall be closed in
    accordance with the 1000-Series Rules.” Dep’t of Nat. Res. Rule
    905(a), 2 Code Colo. Regs. 404-1. The “1000-Series Rules”
    “establish the proper reclamation of the land and soil affected by oil
    and gas operations.” Dep’t of Nat. Res. Rule 1001(a), 2 Code Colo.
    Regs. 404-1. Accordingly, Rule 1003(d)(2) requires that, on
    non-crop land (such as the O’Hares’ ranch), drilling pits be closed
    no later than six months after “drilling and completion activities
    conclude.” Dep’t of Nat. Res. Rule 1003(d)(2), 2 Code Colo. Regs.
    404-1.
    ¶ 55   Rule 1001(c) states that COGCC will not require compliance
    with Rule 1003
    if the operator can demonstrate to the
    Director’s or [COGCC’s] satisfaction both that
    compliance with such rule[] is not necessary to
    protect the public health, safety and
    welfare . . . and that the operator has entered
    into an agreement with the surface owner
    regarding topsoil protection and reclamation of
    the land.
    26
    Dep’t of Nat. Res. Rule 1001(c), 2 Code Colo. Regs. 404-1. Rule
    1001(c) then states that, “[a]bsent bad faith conduct by the
    operator, penalties may only be imposed for non-compliance with a
    [COGCC] order issued after a determination that, notwithstanding
    such agreement, compliance is necessary to protect public health,
    safety and welfare.” 
    Id. ¶ 56
      COGCC concluded that Maralex had violated Rule 905(a) on
    the basis of the two open drilling pits on the Katie Eileen 2 and 3
    location. Maralex contends that it had waived the requirement that
    the pits be closed within six months of the completion of the drilling
    operations by converting the pits into stock ponds. Further,
    Maralex contends that the second sentence of Rule 1001(c)
    “precludes any fine being levied against [it] for failing to reclaim the
    stock ponds” because COGCC never determined that compliance
    with Rule 1003 was necessary to protect public health, safety, and
    welfare.
    ¶ 57   COGCC rejected Maralex’s interpretation of Rule 1001(c),
    stating that, in order to waive the closure requirements, the surface
    owner must get COGCC approval for delaying closure or
    reclamation. It was undisputed that COGCC had not granted
    27
    Maralex a waiver or variance approving the use of the open pits as
    stock ponds.
    ¶ 58   An agency’s interpretation of its own rule is entitled to great
    deference. Abromeit v. Denver Career Serv. Bd., 
    140 P.3d 44
    , 49
    (Colo. App. 2005). Thus, we will accept COGCC’s interpretation if it
    has a reasonable basis in law and is warranted by the record. See
    Bd. of Cty. Comm’rs v. Colo. Oil & Gas Conservation Comm’n, 
    81 P.3d 1119
    , 1125 (Colo. App. 2003). Here, we accept COGCC’s
    interpretation of Rule 1001(c) as imposing a requirement that an
    operator affirmatively seek a waiver before being able to invoke the
    protection of the rule’s second sentence.
    ¶ 59   Accordingly, we conclude there is no basis for reversing
    COGCC’s determination that Maralex violated Rule 905(a).
    D. Rule 907(a)(1)
    ¶ 60   COGCC has defined exploration and production waste as
    “wastes associated with operations to locate or remove oil or gas
    from the ground.” Dep’t of Nat. Res. Rule 100, 2 Code Colo. Regs.
    404-1. Rule 907(a) generally requires that operators properly store,
    handle, or dispose of exploration and production waste. Dep’t of
    Nat. Res. Rule 907(a), 2 Code Colo. Regs. 404-1. The rule also
    28
    refers to a table, Table 910-1, setting forth acceptable concentration
    levels of various contaminants. 
    Id. Operators must
    manage
    exploration and production waste “to the extent necessary to ensure
    compliance” with Table 910-1. 
    Id. ¶ 61
      COGCC concluded that Maralex violated Rule 907(a)(1) at the
    Katie Eileen 2 and 3 location based on exploration and production
    waste observed in the pit with the partially torn liner. According to
    the OFV, the violation was based only on the presence of
    “weathered drill cuttings” in the pit, which were visible due to the
    contrast in color between the cuttings and the native soil.
    ¶ 62   At the agency’s hearing, COGCC’s environmental protection
    specialist also testified that, based on soil samples he had taken
    from the edge of the pit, the soil exceeded the permissible levels of
    electrical conductivity, sodium absorption, and arsenic. However,
    the environmental protection specialist did not take background
    samples that would show that the elevated levels were unique to the
    area around the pit and not merely common to the nearby soil.
    ¶ 63   Maralex contends that COGCC staff erred in failing to take
    background soil samples. We conclude that Maralex’s reliance on
    the footnote in Table 910-01 is misplaced. While that footnote
    29
    states that “[c]onsideration shall be given to background
    [contaminant] levels in native soils,” Dep’t of Nat. Res. Table 910-1
    n.1, 2 Code Colo. Regs. 404-1, nothing in COGCC’s rules mandates
    that an inspector take background soils samples.
    ¶ 64   Regardless, COGCC’s conclusion with regard to Rule 907(a)(1)
    was based only on the inspectors’ testimony and photographs
    demonstrating that there were drill cuttings in the pit with the torn
    liner. Specifically, the OFV read, “[COGCC] finds Maralex in
    violation of Rule 907.a(1) at the Katie Eileen 2 [and] 3 Location,
    because drill cuttings were not properly treated or stored in the pit
    with the torn liner.” Because that finding is supported by
    substantial evidence, we perceive no basis for reversing the agency’s
    decision that Maralex violated Rule 907(a)(1).
    V. Conclusion
    ¶ 65   Accordingly, the district court’s order enforcing COGCC’s OFV
    is reversed insofar as it upheld the agency’s determination that
    Maralex violated Rule 204 on March 20, 2014, and assessed a
    $2000 penalty for that violation. In all other respects, the district
    court’s order is affirmed. We remand to the district court to return
    30
    the case to COGCC for further proceedings consistent with this
    opinion.
    JUDGE BOORAS and JUDGE CASEBOLT concur.
