    Roske-Martinez, Sonora Brinkley, Aerielle Deering, Trinity Carter,
    and Emma Bray (collectively Petitioners), who reside and recreate in
    Colorado, appeal the district court’s order and final judgment
    affirming a decision of the Colorado Oil and Gas Conservation
    Commission (the Commission) denying Petitioners’ rulemaking
    petition. The American Petroleum Institute and the Colorado
    Petroleum Association (collectively Intervenors) intervened in the
    district court and filed an appellate brief supporting the district
    court’s order. Additionally, on appeal, twenty-nine agencies and
    interest groups join as amici curiae, collectively filing three amici
    briefs.1

    ¶2    This appeal concerns the scope of authority and obligation
    delegated to the Commission by the General Assembly in the Oil
    and Gas Conservation Act (the Act), §§ 34-60-101 to -130, C.R.S.
    2016, to regulate oil and gas production in the interests of public
    health and safety. The district court affirmed the Commission’s
    order after concluding that the Commission lacked authority to
    consider a proposed rule that would require it to readjust the Act’s
    balance between the development of oil and gas resources and
    protection of public health, safety, and welfare. Because we agree
    with Petitioners that this conclusion was erroneous, we reverse the
    judgment of the district court and the decision of the Commission
    and remand to the district court to return the case to the
    Commission for further proceedings consistent with this opinion.
    I.   Background

    hold open, fractures in a well bore allowing oil and gas to flow to the
    well bore via the newly created fractures. City of Longmont v. Colo.
    Oil & Gas Ass’n, 
    2016 CO 29
    , ¶ 1.
    ¶4    The Commission is charged with generally regulating oil and
    gas resource production in Colorado. See § 34-60-105, C.R.S.
    2016; § 34-60-106, C.R.S. 2016.
    ¶5    On November 15, 2013, Petitioners filed a petition for
    rulemaking pursuant to the Commission’s Rule 529(b). See Dep’t of
    Nat. Res. Reg. 529, 2 Code Colo. Regs. 404-1. Petitioners proposed
    a rule requesting that the Commission
    not issue any permits for the drilling of a well
    for oil and gas unless the best available
    science demonstrates, and an independent,
    third party organization confirms, that drilling
    can occur in a manner that does not
    cumulatively, with other actions, impair
    Colorado’s atmosphere, water, wildlife, and
    land resources, does not adversely impact
    human health and does not contribute to
    climate change.
    ¶6    The Commission solicited and received written stakeholder
    comments and held a hearing, on April 28, 2014, where parties
    favoring and opposing the proposed rule testified.
    3
    ¶7    The Commission ultimately denied the petition, concluding
    that (1) the proposed rule mandated action that was beyond the
    limited statutory authority delegated by the General Assembly in
    the Act; (2) review by a third party — as Petitioners requested —
    contradicted the Commission’s nondelegable duty to promulgate
    rules under section 34-60-106(11)(a)(II) and is contrary to the Act;
    and (3) the public trust doctrine, which Petitioners relied on to
    support their request, has been expressly rejected in Colorado.2
    ¶8    The Commission also concluded that “the Commission and the
    Colorado Department of Public Health and the Environment
    (CDPHE) are currently addressing many of the Petitioners’ concerns
    through more gradual changes in regulation within their relative
    2 In 2016, in City of Longmont v. Colorado Oil and Gas Association,
    
    2016 CO 29
    , the Colorado Supreme Court rejected the adoption of
    the public trust doctrine in Colorado in its more general rejection of
    a local moratorium on fracking which the court concluded was
    preempted by state law. Id. at ¶ 62. Petitioners initially urged the
    Commission to adopt the public trust doctrine in their petition for
    rulemaking but do not reassert their public trust doctrine argument
    on appeal, nor do they contest the Commission’s conclusion as it
    narrowly relates to the public trust doctrine in Colorado. We
    therefore need not address the arguments of the Commission and
    Intervenors that Petitioners’ justifications for the proposed rule,
    under the public trust doctrine, were not valid. See Giuliani v.
    Jefferson Cty. Bd. of Cty. Comm’rs, 
    2012 COA 190
    , ¶ 52 (claim
    raised in complaint but not further litigated was abandoned).
    4
    jurisdictions.” In reaching its conclusions, the Commission largely
    relied on a memo from the Colorado Attorney General’s Office which
    advised that the Commission lacked jurisdiction to adopt the
    proposed rule as written, and that there is no statutory basis to
    withhold drilling permits pending the Petitioners’ proposed impact
    reviews.3
    ¶9     On July 3, 2014, Petitioners appealed the Commission’s
    decision to the district court pursuant to the State Administrative
    Procedure Act, § 24-4-106, C.R.S. 2016. The parties filed briefs and
    Petitioners requested oral argument.
    ¶ 10   The district court, ruling on the briefs, applied the two-part
    test from Chevron, U.S.A., Inc. v. Natural Resources Defense Council,
    Inc., 
    467 U.S. 837
     (1984), and concluded that the Act’s language is
    clear and unambiguous and requires a balance between the
    development of oil and gas resources and protecting public health,
    safety, and welfare. The district court further concluded that the
    Commission did not act arbitrarily or capriciously in relying on the
    advice of the Attorney General’s Office, and that it rationally decided
    3 By relying on the memo, the Commission waived any attorney-
    client privilege in the memo.
    5
    to deny the petition after considering input from stakeholders on
    both sides of the fracking issue. Thus, the district court affirmed
    the Commission.
    II.   The Commission’s Duty Under the Act
    ¶ 11   Petitioners contend that the district court and the Commission
    erred in interpreting the Act. We agree.
    A.    Preservation and Standard of Review
    ¶ 12   The parties agree that Petitioners preserved their argument for
    appeal.
    ¶ 13   We may overturn an administrative agency’s determination
    only if we conclude that the agency (1) acted arbitrarily or
    capriciously; (2) made a determination that is not supported by the
    record; (3) erroneously interpreted the law; or (4) exceeded its
    constitutional or statutory authority. Sapp v. El Paso Cty. Dep’t of
    Human Servs., 
    181 P.3d 1179
    , 1182 (Colo. App. 2008). The district
    court exercises no factfinding authority in its review of an agency
    decision and is in the same position as this court, so we engage in
    the same type of record review as did the district court. 
    Id.
    ¶ 14   We review statutory construction de novo. Archuletta v. Indus.
    Claim Appeals Office, 
    2016 COA 66
    , ¶ 11. While we defer to an
    6
    agency’s policy determinations in rulemaking proceedings, that
    deference does not extend to “questions of law such as the extent to
    which rules and regulations are supported by statutory authority.”
    Simpson v. Cotton Creek Circles, LLC, 
    181 P.3d 252
    , 261 (Colo.
    2008). Under Chevron, the first step in reviewing an agency’s
    interpretation of a statute involves using traditional tools of
    statutory construction to determine whether the language of the
    statute is clear and whether the legislature has spoken directly to
    the question at issue. 
    467 U.S. at 842-43
    . We begin interpreting a
    statute by looking to the plain and ordinary meaning of the
    language. Robinson v. Legro, 
    2014 CO 40
    , ¶ 14. We “read and
    consider the statutory scheme as a whole to give consistent,
    harmonious and sensible effect to all its parts.” 
    Id.
     (citation
    omitted). We presume the legislature intended the entire statute to
    be effective and avoid constructions that would render any part
    meaningless. 
    Id.
     “When we interpret a comprehensive legislative
    scheme, we must give meaning to all portions thereof and construe
    the statutory provisions to further the legislative intent.” Droste v.
    Bd. of Cty. Comm’rs, 
    159 P.3d 601
    , 605 (Colo. 2007). If the
    7
    statutory intent is plain and unambiguous, our inquiry ends there.
    See Chevron, 
    467 U.S. at 842-43
    .
    B.       Law
    ¶ 15   The Commission is a creature of state statute and has only the
    powers conferred on it by the Act. Chase v. Colo. Oil & Gas
    Conservation Comm’n, 
    2012 COA 94
    , ¶ 26. The Act grants the
    Commission broad jurisdiction and empowers it to “make and
    enforce rules, regulations, and orders” and “to do whatever may
    reasonably be necessary” to carry out the provisions of the Act. 
    Id.
    (quoting § 34-60-105(1)). Pursuant to the Act, the Commission is
    authorized to regulate “the drilling, producing, and plugging of wells
    and all other operations for the production of oil and gas.”
    § 34-60-106(2)(a).
    ¶ 16   Significantly here, the General Assembly declares that 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. 2016 (emphasis added).
    8
    C.    Analysis
    ¶ 17   The Commission interpreted section 34-60-102(1)(a)(I) as
    requiring a balance between oil and gas production and public
    health, safety, and welfare. The Commission concluded that
    Petitioners’ suggested interpretation would “have required the
    Commission to readjust the balance crafted by the General
    Assembly under the Act, and is therefore beyond the Commission’s
    limited grant of statutory authority.”
    ¶ 18   Petitioners argue that the Commission’s interpretation renders
    the phrase “in a manner consistent with protection of public health,
    safety, and welfare” in section 34-60-102(1)(a)(I) superfluous.
    Petitioners further contend that the balance sought by the General
    Assembly in section 34-60-102(1)(a)(I) applies to the development,
    production, and utilization of oil and gas resources, which must be
    authorized in a balanced manner — meaning without causing waste
    — and subject to adequate consideration of public health, safety,
    and environmental and wildlife impacts. Petitioners maintain that
    the Commission incorrectly interpreted the plain language of
    section 34-60-102(1)(a)(I) and, in doing so, erred in denying their
    petition for rulemaking.
    9
    ¶ 19   We agree with Petitioners, the Commission, and the district
    court that the language of section 34-60-102(1)(a)(I) is clear and
    unambiguous, but we conclude that it unambiguously supports a
    conclusion different from that reached by the Commission and the
    district court. The Act clearly states that fostering “responsible,
    balanced development, production, and utilization of the natural
    resources” is in the public interest. § 34-60-102(1)(a)(I). Then, the
    Act qualifies itself by adding the key phrase “in a manner consistent
    with” the protection of public health and other related concerns.
    Id.; see also City of Jefferson City v. Cingular Wireless, LLC, 
    531 F.3d 595
    , 611 (8th Cir. 2008) (the fact that parties disagree about
    what a statute means does not itself create ambiguity).
    ¶ 20   Contrary to the Commission’s conclusion, the use, in section
    34-60-102(1)(a)(I), of the term “balanced” relates to and modifies
    “development, production, and utilization.” As used in the plain
    text, “balanced” is an adjective which modifies the nouns
    “development, production, and utilization.” See § 34-60-102(1)(a)(I);
    see also Double D Manor, Inc. v. Evergreen Meadows Homeowners’
    Ass’n, 
    773 P.2d 1046
    , 1048 (Colo. 1989) (an adjective modifies a
    noun that follows it). The remaining provisions in section
    10
    34-60-102(1)(a)(I) are not affected by the term “balanced.”4 Instead,
    the statutory language provides that fostering balanced
    development is in the public interest when that balanced
    development is completed “in a manner consistent with” public
    health, safety, and environmental and wildlife impacts.
    § 34-60-102(1)(a)(I); see also Gerrity Oil & Gas Corp. v. Magness,
    
    946 P.2d 913
    , 925 (Colo. 1997) (recognizing that the Act’s purposes
    are “to encourage the production of oil and gas in a manner that
    protects public health and safety and prevents waste”).
    ¶ 21   Critical here is the proper interpretation of the phrase “in a
    manner consistent with.” We agree with Petitioners that “in a
    manner consistent with” does not indicate a balancing test but
    rather a condition that must be fulfilled. This interpretation is
    supported by similar interpretations from our supreme court as well
    4 This is demonstrated by the historical importance of the General
    Assembly qualifying “development, production, and utilization” with
    the adjective “balanced.” As further explained below, in our
    discussion of the Act’s legislative evolution, the General Assembly
    sought balanced development, production, and utilization to curb
    unnecessary waste and to preserve the correlative rights of other
    potential users of natural resources such as oil and gas.
    11
    as the commonly understood use of the phrase as evidenced by its
    general use in statutes and judicial opinions.
    ¶ 22   The Colorado Supreme Court, when asked to interpret certain
    provisions of the Local Government Land Use Control Enabling Act
    of 1974, § 29-20-102, C.R.S. 2016, explicitly and clearly interpreted
    the phrase “in a manner consistent with” as meaning “subject to.”
    See Droste, 159 P.3d at 606. There, the court interpreted the
    statutory phrase “in a manner consistent with constitutional rights”
    as meaning “subject to the constitutional rights of the property
    owner[.]” Id. This interpretation supports our conclusion that the
    language of the Act does not create a balancing test weighing safety
    and public health interests against development of oil and gas
    resources, but rather, the Act indicates that fostering balanced,
    nonwasteful development is in the public interest when that
    development is completed subject to the protection of public health,
    safety, and welfare, including protection of the environment and
    wildlife resources. See § 34-60-102(1)(a)(I).
    ¶ 23        Interpreting the phrase “in a manner consistent with” as
    a balancing test disregards the plain meaning of the phrase. The
    phrase denotes more than a mere balancing. Cases in Colorado are
    12
    replete with instances where the phrase is used to denote “subject
    to” rather than “balanced with.” See, e.g., People v. Baez-Lopez,
    
    2014 CO 26
    , ¶ 28 (“[W]e conclude that the recordings were
    physically sealed and preserved in a manner consistent with section
    16-15-102(8)(a).”); In re Great Outdoors Colo. Tr. Fund, 
    913 P.2d 533
    , 539 (Colo. 1996) (“In enacting legislation, the General
    Assembly is authorized to resolve ambiguities in constitutional
    amendments in a manner consistent with the terms and underlying
    purposes of the constitutional provisions.”); Stan Clauson Assocs.,
    Inc. v. Coleman Bros. Constr., LLC, 
    2013 COA 7
    , ¶ 10 (“Professional
    standards of care reflect the policy that members of professions
    must do their work not just reasonably well, but rather ‘in a
    manner consistent with members of the profession in good
    standing.’” (quoting Command Commc’ns, Inc. v. Fritz Cos., 
    36 P.3d 182
    , 189 (Colo. App. 2001))).
    ¶ 24   The phrase is often used in the dispositional language of
    opinions from this court and other appellate courts. Divisions of
    this court, when remanding a case to a district court for further
    proceedings, often use language similar to “the case is remanded for
    proceedings in a manner consistent with this opinion.” See
    13
    Vashone-Caruso v. Suthers, 
    29 P.3d 339
    , 345 (Colo. App. 2001); 1st
    Am. Sav. Bank v. Boulder Cty. Bd. of Comm’rs, 
    888 P.2d 360
    , 363
    (Colo. App. 1994). The intention of the phrase “in a manner
    consistent with” in these settings is not to instruct a court on
    remand to take action in a manner “balanced with” the opinion
    from the appellate court, but instead instructs that the court on
    remand must take action subject to the appellate opinion.
    ¶ 25   As used in the Act, the phrase qualifies the preceding
    provision, promoting the development of oil and gas. See
    § 34-60-102(1)(a)(I). We therefore conclude that the Commission
    erred in interpreting section 34-60-102(1)(a)(I) as requiring a
    balance between development and public health, safety, and
    welfare. The plain meaning of the statutory language indicates that
    fostering balanced, nonwasteful development is in the public
    interest when that development is completed subject to the
    protection of public health, safety, and welfare. See
    14
    § 34-60-102(1)(a)(I); see also Gerrity Oil & Gas Corp., 946 P.2d at
    925.5
    ¶ 26   Our interpretation also gives meaning to all of the words in the
    statute, whereas the Commission’s interpretation effectively
    disregarded the phrase “in a manner consistent with.” See Legro,
    ¶ 14 (we avoid statutory constructions that would render any part
    of a statute meaningless).
    ¶ 27   We disagree with the Commission and its amici that other
    sections of the Act support a contrary interpretation. The
    Commission argues that the language of section 34-60-106(2)(d) —
    stating that the Commission has the authority to regulate “[o]il and
    5 Moreover, the Colorado Revised Statutes contain many examples
    of instances where the General Assembly has articulated clear
    intent that a balancing test be employed, and such language is not
    contained in the Act. See, e.g., § 24-91-101(2), C.R.S. 2016
    (“[T]here is a substantial statewide interest in ensuring that the
    policy underlying the efficient expenditure of public moneys is
    balanced with the policy of fostering a healthy and viable
    construction industry.”); § 6-1-902(1)(c), C.R.S. 2016 (“Individuals’
    privacy rights and commercial freedom of speech should be
    balanced in a way that accommodates both the privacy of
    individuals and legitimate telemarketing practices[.]”). Had the
    General Assembly intended for a balancing test to be applied in
    section 34-60-102(1)(a)(I), C.R.S. 2016, it would have explicitly said
    so. See Showpiece Homes Corp. v. Assurance Co. of Am., 
    38 P.3d 47
    , 57 (Colo. 2001).
    15
    gas operations so as to prevent and mitigate significant adverse
    environmental impacts . . . to the extent necessary to protect public
    health, safety, and welfare . . . taking into consideration
    cost-effectiveness and technical feasibility[]” — demonstrates that
    the Act calls for the balance that the Commission read into the
    language of section 34-60-102. However, section 34-60-106(2)(d)
    supports the conclusion that the Commission has authority to
    promulgate rules regulating oil and gas development in the interest
    of protecting public health, safety, and welfare. See § 34-60-
    106(2)(d). The General Assembly’s use of the phrase “to the extent
    necessary to protect public health, safety, and welfare,” when
    describing the purpose of regulation, evidences a similar intent to
    elevate the importance of public health, safety, and welfare above a
    mere balancing — the same as what the General Assembly wrote
    into section 34-60-102.6 Section 34-60-106(2)(d) in no way
    conflicts with our interpretation of section 34-60-102.
    6 The statutory language “to the extent necessary” evidences the
    General Assembly’s intent to create a mandatory condition rather
    than a factor in a general balancing inquiry. See, e.g., Calderon v.
    Am. Family Mut. Ins. Co., 
    2016 CO 72
    , ¶ 53 (insurance statutes
    intended that benefit be provided “to the extent necessary” for full
    16
    ¶ 28   Our conclusion is further supported by the evolution of the
    General Assembly’s regulation of the oil and gas industry in
    Colorado and its numerous alterations to the language of the Act.
    Originally, the Act contained no qualifying language regarding
    responsible, balanced development, or the protection of public
    health and the environment. See Ch. 208, sec. 10, § 100-6-22,
    
    1955 Colo. Sess. Laws 657
    . For decades, the Act read: “It is hereby
    declared to be in the public interest to foster, encourage and
    promote the development, production and utilization of the natural
    resources of oil and gas in the state of Colorado[.]”

    ¶ 29   In 1994 the General Assembly added the language “in a
    manner consistent with protection of public health, safety, and
    welfare[.]” Ch. 317, sec. 2, § 34-60-102, 
    1994 Colo. Sess. Laws 1978
    . Then, in 2007, the General Assembly completed the Act as it
    reads today by amending and adding language so that the statute
    read: “It is declared to be in the public interest to foster . . .
    compensation) (citing Kral v. Am. Hardware Mut. Ins. Co., 
    784 P.2d 759
    , 765 (Colo. 1989)); People in Interest of G.S., 
    820 P.2d 1178
    ,
    1180 (Colo. App. 1991) (a guardian ad litem has the affirmative
    duty to participate in proceedings “to the extent necessary” to
    represent the child).
    17
    responsible, balanced [resource] development[.]” Ch. 320, sec. 1,
    § 34-60-102, 
    2007 Colo. Sess. Laws 1357
    .
    ¶ 30   These amendments reflect the General Assembly’s general
    movement away from unfettered oil and gas production and
    incorporation of public health, safety, and welfare as a check on
    that development. This understanding supports our conclusion
    that the Act was not intended to require that a balancing test be
    applied when agencies charged with carrying out and enforcing the
    intent behind the Act, like the Commission, make decisions on
    regulation, including a decision denying a petition for a proposed
    rule. Rather, the clear language of the Act — supported by the Act’s
    legislative evolution and the Commission’s own enforcement criteria
    — mandates that the development of oil and gas in Colorado be
    regulated subject to the protection of public health, safety, and
    welfare, including protection of the environment and wildlife
    resources. See Oil & Gas Conservation Comm’n, Colorado Oil and
    Gas Conservation Commission Enforcement Guidance and Penalty
    Policy 1 (Jan. 2015), https://perma.cc/39RU-99MF (“In Colorado
    . . . the development of . . . natural resources must be consistent
    with protection of public health, safety, and welfare, including the
    18
    environment and wildlife resources, at all times[.]”); see also § 34-
    60-106(2)(d).
    ¶ 31   Because we conclude that the district court and the
    Commission erroneously interpreted the Act, we reverse. Nixon v.
    City & Cty. of Denver, 
    2014 COA 172
    , ¶ 12 (an agency abuses its
    discretion when it erroneously interprets the law). The record
    indicates that the Commission based its denial of the petition for
    rulemaking primarily on its determination that it lacked authority
    to implement Petitioners’ proposed rule. The administrative record
    does not contain sufficient findings of fact for us to affirm the
    Commission’s decision on alternative grounds — such as the
    Commission’s statement that “there are other Commission priorities
    that must take precedence over the proposed rulemaking at this
    time,” or the Commission’s reference to the proposed rule’s
    impermissible delegation of Commission duties to a third party (an
    issue not addressed by the district court or briefed on appeal to this
    court). See Chase, ¶ 59 (remand proper when record contains
    insufficient basis for agency conclusions).
    ¶ 32   Our decision does not address the merits of whether the
    Commission should adopt Petitioners’ proposed rule. Our review is
    19
    limited to the Commission’s rejection of Petitioners’ proposed rule
    based on the Commission’s determination that such action would
    exceed its statutory authority under the Act — which is legally
    incorrect. See, e.g., United States v. Allegheny-Ludlum Steel Corp.,
    
    406 U.S. 742
    , 749 (1972) (Courts do not “inquire into the wisdom of
    the regulations” that a commission promulgates but, instead,
    inquire into “the soundness of the reasoning by which [a]
    [c]ommission reaches its conclusions.”).
    ¶ 33   The Commission argues that under Massachusetts v.
    Environmental Protection Agency, 
    549 U.S. 497
    , 527-28 (2007),
    judicial review of denials of rulemaking petitions is limited and
    deferential. True, but a denial of a rulemaking petition remains
    properly the subject of judicial review. See id.; Am. Horse Prot.
    Ass’n, Inc. v. Lyng, 
    812 F.2d 1
    , 4 (D.C. Cir. 1987) (agency refusals
    to institute rulemaking proceedings are subject to judicial review).
    Unlike in Massachusetts v. Environmental Protection Agency, where
    the Supreme Court concluded, on the merits, that the
    Environmental Protection Agency’s refusal to promulgate a
    proposed rule was an abuse of discretion, 
    549 U.S. at 528, 534
    , our
    decision does not reach the merits of whether the Commission
    20
    abused its discretion in refusing to promulgate Petitioners’
    proposed rule. Instead, our decision only addresses the
    Commission’s interpretation of its authority under the Act as a part
    of its denial of the petition for rulemaking, which we conclude is
    incorrect. See Allegheny-Ludlum, 
    406 U.S. at 749
    .
    III.   Constitutional Contentions
    ¶ 34   Petitioners contend that the Commission’s interpretation of
    the Act is an unconstitutional infringement of Petitioners’ natural
    rights to enjoy their lives and liberties, protect their property, and
    obtain their safety and happiness. Colo. Const. art. II, § 3.
    ¶ 35   Because we conclude that the Commission erred in its
    interpretation of the Act and reverse, we need not address
    Petitioners’ constitutional arguments. See City of Florence v.
    Pepper, 
    145 P.3d 654
    , 660 (Colo. 2006) (“Where possible, we avoid a
    constitutional analysis in favor of a statutory resolution.”); Club
    Matrix, LLC v. Nassi, 
    284 P.3d 93
    , 99 (Colo. App. 2011) (we need not
    address additional arguments rendered moot by our ultimate
    disposition).
    21
    IV.   Conclusion
    ¶ 36   The Commission’s order denying Petitioners’ petition for
    rulemaking and the district court’s order on appeal are reversed,
    and the case is remanded to the district court to return it to the
    Commission for further proceedings consistent with this opinion.
    JUDGE VOGT concurs.
    JUDGE BOORAS dissents.
    22
    JUDGE BOORAS, dissenting.
    ¶ 37   I disagree with the majority’s interpretation of the phrase “in a
    manner consistent with” and its reliance on a legislative declaration
    to find a mandatory duty. Therefore, I respectfully dissent from the
    majority’s conclusion that the statutory scheme of the Oil and Gas
    Conservation Act (the Act), §§ 34-60-101 to -130, C.R.S. 2016,
    requires protection of public health, safety, and welfare as a
    determinative factor, instead of requiring balancing between those
    considerations and oil and gas production.
    ¶ 38   The Colorado Oil and Gas Commission (the Commission)
    discerns that its role under the Act is to balance oil and gas
    development with other public interests. “Courts may only
    disregard an agency’s interpretation of a statute it is charged with
    enforcing when that interpretation is inconsistent with the clear
    language of the statute or the agency has exceeded the scope of the
    statute.” Huber v. Kenna, 
    205 P.3d 1158
    , 1164 (Colo. 2009) (citing
    Chevron, U.S.A., Inc. v. Nat. Res. Def. Council, Inc., 
    467 U.S. 837
    ,
    844 (1984)).
    ¶ 39   The majority concludes that the Commission’s interpretation
    of the Act is inconsistent with the clear language of the Act, in
    23
    particular section 34-60-102(1)(a)(I), C.R.S. 2016, which provides
    that it is in the public interest to:
    Foster 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.
    ¶ 40   In order to reach this conclusion, the majority examines the
    use of the phrase “in a manner consistent with” in a number of
    unrelated contexts, largely relying on remand language from
    opinions, and surmises that it does not indicate “balancing,” but
    rather “a condition that must be fulfilled” or “subject to.” But
    Webster’s Third New International Dictionary defines “consistent
    with” as “to be consistent, harmonious, or in accordance,” and
    “consistently” as “compatibly,” “congruously,” “in harmony with,”
    and “in a persistent or even manner.”1 Webster’s Third New
    International Dictionary Unabridged 484 (2002). Contrary to the
    majority’s supposition, these definitions signify a balancing process.
    1 The use of a dictionary is appropriate to interpret undefined
    statutory terms. Bontrager v. La Plata Elec. Ass’n Inc., 
    68 P.3d 555
    ,
    559 (Colo. App. 2003) (citing 2A Norman J. Singer, Sutherland on
    Statutory Construction § 47.27 (6th ed. 2000)).
    24
    ¶ 41   Significantly, the language on which the majority primarily
    relies to support its view that protection of public health, safety,
    and welfare is a mandatory precondition is located in the legislative
    declaration to the Act. Even when codified, a legislative declaration
    is primarily “an explicit or formal statement or announcement
    about the legislation” that “indicates the problem the General
    Assembly is trying to address.” Lester v. Career Bldg. Acad., 
    2014 COA 88
    , ¶ 27 (citation omitted). Generally, a legislative declaration
    is used only to interpret a statute that is ambiguous; it cannot
    override the language of a statute. See § 2-4-203(1)(g), C.R.S. 2016
    (identifying the legislative declaration or purpose as an aid in
    construing ambiguous statutes); People in Interest of T.B., 2016
    COA 151M, ¶¶ 41, 42, as modified on denial of reh’g (Dec. 29, 2016)
    (noting that courts generally do not consider a legislative
    declaration where a statute is unambiguous and that a legislative
    declaration cannot override a statute’s language); see also People v.
    Ennea, 
    665 P.2d 1026
    , 1029 (Colo. 1983) (rejecting the defendant’s
    attempt to add an element to the sexual exploitation of a child
    statute based on language in the legislative declaration).
    25
    ¶ 42   The actual authority of the Commission to regulate oil and gas
    is set out in section 34-60-106(2)(d), C.R.S. 2016:
    The commission has the authority to regulate
    . . . [o]il and gas operations so as to prevent
    and mitigate significant adverse environmental
    impacts on any air, water, soil, or biological
    resource resulting from oil and gas operations
    to the extent necessary to protect public
    health, safety, and welfare, including
    protection of the environment and wildlife
    resources, taking into consideration cost-
    effectiveness and technical feasibility.
    (Emphasis added.)
    ¶ 43   The majority concludes that this section also supports its
    view, construing the use of “to the extent necessary” as evidencing
    “a similar intent to elevate the importance of public health, safety,
    and welfare above a mere balancing.” However, the statute, read as
    a whole, directs the Commission to “prevent and mitigate significant
    adverse environmental impacts,” and also to take into consideration
    “cost-effectiveness and technical feasibility.” There would be no
    reason to consider cost-effectiveness and technical feasibility if
    protection of the public health, safety, and welfare was, by itself, a
    determinative consideration.
    26
    ¶ 44   Because the Commission is required by statute to regulate oil
    and gas operations by balancing the relevant considerations, the
    Commission properly denied Petitioners’ petition for rulemaking,
    which would have required the Commission to view public health
    and environmental considerations as being determinative. The
    majority characterizes this denial as a “refusal to engage in the
    rulemaking process.” The majority may be focusing on the use of
    the word “jurisdiction” in the Commission’s order.2 However, a
    careful reading of the order reveals that the Commission deemed
    the proposed rulemaking to be outside its statutory authority, not
    outside of its jurisdiction.
    ¶ 45   Even Petitioners conceded in the district court that the
    Commission “did not claim that it doesn’t have the jurisdiction to
    promulgate a rule,” but rather that it did not have the authority
    under the statute to promulgate the rule Petitioners were requesting
    2 The Commission’s order primarily used the word “authority.”
    However, the order used the word “jurisdiction” referring to a memo
    that had been prepared by the Colorado Attorney General’s office
    regarding the Colorado Department of Public Health and
    Environment’s expertise in air quality. See People v. Sherrod, 
    204 P.3d 466
    , 470 (Colo. 2009) (noting that there is sometimes
    “analytical confusion” between the terms “authority” and
    “jurisdiction”).
    27
    — to view health and environmental concerns as overriding.
    Indeed, as discussed above, the Commission’s interpretation that
    the statute requires a balancing of interests is correct.
    ¶ 46   The Commission has consistently recognized its duty to
    balance health and environmental concerns with the promotion of
    oil and gas development. Our supreme court noted in City of Fort
    Collins v. Colorado Oil & Gas Association, 
    2016 CO 28
    , ¶ 29, that,
    consistent with its legislative authorization, “the Commission has
    promulgated an exhaustive set of rules and regulations ‘to prevent
    waste and to conserve oil and gas in the State of Colorado while
    protecting public health, safety, and welfare.’ Dep’t of Nat. Res.
    Reg. 201, 2 [Code Colo.] Regs. 404–1 (2015).”
    ¶ 47   For these reasons, I would affirm the district court’s order
    upholding the Commission’s order denying Petitioners’ petition for
    rulemaking. In concluding that the district court order should be
    affirmed, I would also reject the Petitioners’ constitutional
    arguments based on the public trust doctrine and that the
    Commission’s interpretation of the Act is an unconstitutional
    infringement of Petitioners’ natural rights to enjoy their lives and
    liberties, protect their property, and obtain their safety and
    28
    happiness. The Colorado Supreme Court declined to apply the
    public trust doctrine in City of Longmont v. Colorado Oil & Gas
    Association, 
    2016 CO 29
    , ¶ 62.
