EPA Approved Statutes and Regulations in the Colorado SIP

§ 52.319 Conditional approval.

(a) The EPA is conditionally approving portions of the Colorado SIP revisions submitted on May 14, 2018 and May 13, 2020. The conditional approval is based upon the October 20, 2021 commitment from the State to submit a SIP revision consisting of rule revisions that will cure the identified deficiencies by June 30, 2022. If the State fails to meet its commitment, the conditional approval will be treated as a disapproval with respect to the rules and CTG category for which the corrections are not met. The following are conditionally approved:

(1) Regulation number 7, Section XII.J.1. from the May 14, 2018 submittal and Part D, Sections I.D.-D.3.a.(i), I.D.3.b.-b.(i), I.D.3.b.(ii), I.D.3.b.(v), I.D.3.b.(vii), I.D.3.b.(ix), I.D.4.-I.E.1.a., I.E.2.-c.(ii), I.E.2.c.(iv)-c.(viii), I.F.-1.d., I.F.1.g.-g.(xii), I.F.1.h.-F.2.a., I.F.2.c.-c.(vi), I.F.3.-3.a, I.F.3.c.-c.(i)(C), and I.J.1.-j. from the May 13, 2020 submittal.

(2) Colorado's determination that Reg. 7, Part D satisfies 2008 ozone NAAQS SIP RACT requirements for the following category, “Control Techniques Guidelines for the Oil and Natural Gas Industry” EPA-453/B-16-001, October 2016.

(b) [Reserved].

[87 FR 29231, May 13, 2022]

§ 52.320 Identification of plan.

(a) Purpose and scope. This section sets forth the applicable State Implementation Plan for Colorado under section 110 of the Clean Air Act, 42 U.S.C. 7410 and 40 CFR part 51 to meet national ambient air quality standards or other requirements under the Clean Air Act.

(b) Incorporation by reference.

(1) Material listed in paragraphs (c) and (d) of this section with an EPA approval date prior to June 1, 2015, was approved for incorporation by reference by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51. Material is incorporated as submitted by the state to EPA, and notice of any change in the material will be published in the Federal Register. Entries for paragraphs (c) and (d) of this section with EPA approval dates after June 1, 2015, will be incorporated by reference in the next update to the SIP compilation.

(2) EPA Region 8 certifies that the rules/regulations provided by EPA in the SIP compilation at the addresses in paragraph (b)(3) of this section are an exact duplicate of the officially promulgated state rules/regulations which have been approved as part of the State Implementation Plan as of June 1, 2015.

(3) Copies of the materials incorporated by reference may be inspected at the Environmental Protection Agency, Region 8, 1595 Wynkoop Street, Denver, Colorado, 80202-1129; Air and Radiation Docket and Information Center, U.S. Environmental Protection Agency, West Building, 1301 Constitution Ave. NW., Washington, DC 20460; and, the National Archives and Records Administration (NARA). For information on the availability of materials from the docket in the EPA Headquarters Library, please call the Office of Air and Radiation (OAR) at (202) 566-1742.
