Final rule.


EPA is approving the State Implementation Plan (SIP) submittal from the State of Oregon to demonstrate that the SIP meets the requirements of section 110(a)(1) and (2) of the Clean Air Act (CAA) for the National Ambient Air Quality Standard (NAAQS) promulgated for ozone on July 18, 1997. EPA finds that the current Oregon SIP meets the following 110(a)(2) infrastructure elements for the 1997 8-hour ozone NAAQS: (A), (B), (C), (D)(ii), (E), (F), (G), (H), (J), (K), (L), and (M).


This action is effective on June 20, 2012.

I. Background

On July 18, 1997, EPA promulgated a new NAAQS for ozone. EPA revised the ozone NAAQS to provide an 8-hour averaging period which replaced the previous 1-hour averaging period, and the level of the NAAQS was changed from 0.12 parts per million (ppm) to 0.08 ppm (62 FR 38856). The CAA requires SIPs meeting the requirements of sections 110(a)(1) and (2) be submitted by states within 3 years after promulgation of a new or revised standard. Sections 110(a)(1) and (2) require states to address basic SIP requirements, including emissions inventories, monitoring, and modeling to assure attainment and maintenance of the standards, so-called “infrastructure” requirements. To help states meet this statutory requirement for the 1997 8-hour ozone NAAQS, EPA issued guidance to address infrastructure SIP elements under section 110(a)(1) and (2).[1] In the case of the 1997 8-hour ozone NAAQS, states typically have met the basic program elements required in section 110(a)(2) through earlier SIP submissions in connection with previous ozone standards. The State of Oregon submitted a certification to EPA on September 25, 2008, certifying that Oregon's SIP meets the infrastructure obligations for the 1997 8-hour ozone NAAQS. The certification included an analysis of Oregon's SIP as it relates to each section of the infrastructure requirements with regard to the 1997 8-hour ozone NAAQS. On February 7, 2012, EPA published a notice of proposed rulemaking (NPR) for the State of Oregon (77 FR 6044) to act on the state's infrastructure SIP for the 1997 ozone NAAQS. Specifically in the NPR, EPA proposed approval of Oregon's SIP as meeting the requirements for the following 110(a)(2) infrastructure elements for the 1997 8-hour ozone NAAQS: (A), (B), (C), (D)(ii), (E), (F), (G), (H), (J), (K), (L), and (M). As discussed in the NPR, this action does not address 110(a)(2)(D)(i) and 110(a)(2)(I). The public comment period for EPA's NPR closed on March 8, 2012. EPA received no comments on the proposed action.

II. Scope of Action

Oregon has not demonstrated authority to implement and enforce the Oregon Administrative Rules within “Indian Country” as defined in 18 U.S.C. 1151.[2] Therefore, this SIP approval does not extend to “Indian Country” in Oregon. See CAA sections 110(a)(2)(A) (SIP shall include enforceable emission limits), 110(a)(2)(E)(i) (State must have adequate authority under State law to carry out SIP), and 172(c)(6) (nonattainment SIPs shall include enforceable emission limits). This is consistent with EPA's previous approval of Oregon's PSD program, in which EPA specifically disapproved the program for sources within Indian Reservations in Oregon because the State had not shown it had authority to regulate such sources. See 40 CFR 52.1987(c). It is also consistent with EPA's approval of Oregon's title V operating permits program. See 59 FR 61820, 61827 (December 2, 1994) (interim approval does not extend to Indian Country); 60 FR 50106, 50106 (September 28, 1995) (full approval does not extend to Indian Country).

III. Final Action

EPA is approving the September 25, 2008, SIP submittal from the State of Oregon to demonstrate that the SIP meets the requirements of section 110(a)(1) and (2) of the CAA for the NAAQS promulgated for ozone on July 18, 1997. EPA is approving the following section 110(a)(2) infrastructure elements for Oregon for the 1997 ozone NAAQS: (A), (B), (C), (D)(ii), (E), (F), (G), (H), (J), (K), (L), (M). EPA is taking no action on infrastructure elements (D)(i) and (I) for the 1997 ozone NAAQS. This action is being taken under section 110 of the CAA.

IV. Statutory and Executive Order Reviews

Under the Clean Air Act, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the Clean Air Act. Accordingly, this action merely approves state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this action:

  • Is not a “significant regulatory action” subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993);
  • 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 Clean Air Act; and
  • Does not provide 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, this rule does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not approved to apply in Indian country located in the state, and EPA notes that it will not impose substantial direct costs on tribal governments or preempt tribal law.

The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this action and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. A major rule cannot take effect until 60 days after it is published in the Federal Register. This action is not a “major rule” as defined by 5 U.S.C. 804(2).

Under section 307(b)(1) of the Clean Air Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by July 20, 2012. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this action for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. This action may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2)).

2.  “Indian country” is defined under 18 U.S.C. 1151 as: (1) All land within the limits of any Indian reservation under the jurisdiction of the United States Government, notwithstanding the issuance of any patent, and including rights-of-way running through the reservation, (2) all dependent Indian communities within the borders of the United States, whether within the original or subsequently acquired territory thereof, and whether within or without the limits of a State, and (3) all Indian allotments, the Indian titles to which have not been extinguished, including rights-of-way running through the same. Under this definition, EPA treats as reservations trust lands validly set aside for the use of a Tribe even if the trust lands have not been formally designated as a reservation.
