Environmental Protection Agency (EPA).


Proposed rule; notice of delegation.


The Environmental Protection Agency (EPA) is proposing to update the Code of Federal Regulations (CFR) to reflect Oklahoma's current New Source Performance Standards (NSPS) delegation status and mailing address for the Oklahoma Department of Environmental Quality (ODEQ). The ODEQ has submitted updated Start Printed Page 31424regulations for delegation of the EPA authority for implementation and enforcement of certain NSPS. The updated State regulations incorporate by reference certain NSPS promulgated by the EPA, as they existed through June 30, 2018.


Written comments on this proposed rule must be received on or before June 25, 2020.


Submit your comments, identified by Docket ID No. EPA-R06-OAR-2010-0580, at or via email to Follow the online instructions for submitting comments.

I. Background

Section 111(c)(1) of the Clean Air Act (CAA), 42 U.S.C. 7411(c)(1), authorizes the EPA to delegate to a state the authority to implement and enforce NSPS promulgated by the EPA under CAA section 111(b) and codified at part 60 of title 40 of the CFR. CAA section 111(c)(2) states that the EPA retains the authority to enforce any applicable NSPS delegated to a state. On March 25, 1982, the EPA approved the delegation of authority to implement and enforce NSPS to Oklahoma (1982 NSPS Delegation). See 47 FR 1785 (April 22, 1982). On October 8, 1999, the EPA updated Oklahoma's NSPS delegation, including specific provisions setting forth the terms and conditions of the delegation of authority for NSPS responsibility to the ODEQ (1999 NSPS Delegation). See 64 FR 57392 (October 25, 1999). Copies of the initial 1982 NSPS Delegation and the 1999 NSPS Delegation updates are included in the docket for this action, both of which contain provisions specifying conditions and limitations applicable to the EPA's delegation of authority to implement and enforce the NSPS in Oklahoma.

Under the terms and conditions of the 1999 NSPS Delegation, “[f]uture provisions of 40 CFR part 60 shall be delegated to ODEQ pursuant to this agreement provided that (1) ODEQ requests delegation and provides copies of the proposed or adopted rules, (2) ODEQ adopts the federal standard without change (e.g., incorporation by reference) and (3) EPA does not object to the delegation within thirty (30) days of ODEQ's request.” See Specific Provision 1 of the 1999 NSPS Delegation.

II. ODEQ's December 23, 2019 NSPS Delegation Update

By letter dated December 23, 2019, the ODEQ requested an update to its NSPS delegation. ODEQ reaffirmed that it retains all required authorities set forth in 40 CFR 60.4 for delegation of a CAA section 111(c) program and all authority identified in the 1982 and 1999 NSPS Delegations. ODEQ provided copies of the duly adopted state regulations which incorporate specifically identified NSPS found at 40 CFR part 60 into the Oklahoma Administrative Code (OAC) 252:100-2 and OAC 252:100 Appendix A, as published in the Oklahoma Register on September 3, 2019 (36 Okla. Reg. 1573) with an effective date of September 15, 2019.[1] These ODEQ regulations are, therefore, at least as stringent as the EPA's rules. See 40 CFR 60.10(a). ODEQ's December 23, 2019, request included the following NSPS in 40 CFR part 60, as they existed through June 30, 2018: 40 CFR part 60, subparts A (except sections 60.4, 60.9, 60.10, and 60.16), D, Da, Db, Dc, E, Ea, Eb, Ec, F, G, Ga, H, I, J, Ja, K, Ka, Kb, L, M, N, Na, O, P, Q, R, S, T, U, V, W, X, Y, Z, AA, AAa, BB, BBa, CC, DD, EE, GG, HH, KK, LL, MM, NN, PP, QQ, RR, SS, TT, UU, VV, VVa, WW, XX, BBB, DDD, FFF, GGG, GGGa, HHH, III, JJJ, KKK, LLL, NNN, OOO, PPP, QQQ, RRR, SSS, TTT, UUU, VVV, WWW, XXX, AAAA, CCCC, EEEE, IIII, JJJJ, KKKK, LLLL, OOOO, OOOOa, TTTT, and Appendices A and B to 40 CFR part 60.[2] In accordance with the authority provided by CAA section 111(c)(1) and consistent with the provisions of the 1982 NSPS Delegation and the 1999 NSPS Delegation, the EPA has determined that the ODEQ has met the conditions required for approval of the ODEQ's requested update to its NSPS delegation, as described above. All authorities not affirmatively and expressly requested by the ODEQ are not delegated. In addition, the provisions and conditions contained in the 1982 and 1999 NSPS Delegations remain in effect, including Specific Provision 7 of the 1999 NSPS Delegation which states that the delegation excludes the State's authority for sources located on Indian lands.[3] Furthermore, no authorities are delegated that require rulemaking in the Federal Register to implement, or where Federal overview is the only way to ensure national consistency in the application of the standards. All inquiries and requests concerning implementation and enforcement of the excluded standards in the State of Oklahoma should be directed to the EPA Region 6 Office of Enforcement and Compliance Assurance. Furthermore, the EPA retains any authority in an individual NSPS that may not be delegated according to provisions of the standard. Finally, the EPA retains the Start Printed Page 31425authorities stated in the 1982 and 1999 NSPS Delegations.

III. Proposed Action

Apart from the notification of the updated NSPS delegation to the ODEQ as discussed above, the EPA is proposing to amend 40 CFR part 60 to include a table of the specific NSPS delegated to the ODEQ and update the mailing address for the ODEQ. If finalized as proposed, 40 CFR 60.4(b)(38) will be amended to read: State of Oklahoma: State of Oklahoma, Department of Environmental Quality, Air Quality Division, P.O. Box 1677, Oklahoma City, OK 73101-1677, and the following language and table will be added to 40 CFR 60.4(e):

IV. Statutory and Executive Order Reviews

Under the CAA, the EPA previously delegated to the ODEQ the authority to implement and enforce certain NSPS for sources located in Oklahoma, as provided for under 42 U.S.C. 7411(c)(1); see also 40 CFR 60.4(b). Pursuant the terms and conditions of that delegation, this action informs the public that the EPA has found the ODEQ's December 23, 2019, request to update the delegation status for NSPS meets Federal requirements and does not impose additional requirements beyond those imposed by state law. Through this action, the EPA is proposing to add a table to 40 CFR part 60 listing the specific NSPS currently delegated to the ODEQ and update the ODEQ's address for submittal of documents required under the delegated NSPS provisions. For these reasons, this action:

  • Is not a “significant regulatory action” subject to review by the Office of Management and Budget under Executive Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
  • Is not an Executive Order 13771 (82 FR 9339, February 2, 2017) regulatory action because NSPS delegation updates are exempted under Executive Order 12866;
  • Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
  • Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.);
  • Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4);
  • Does not have federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);
  • Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);
  • Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);
  • Is not subject to requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and
  • Does not provide the EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994).

In addition, the Oklahoma NSPS delegation does not extend to Indian country. If finalized as proposed, the EPA's action will not have tribal Start Printed Page 31427implications and will not impose substantial direct costs on tribal governments or preempt tribal law as specified by Executive Order 13175 (65 FR 67249, November 9, 2000).
