Background On July 18, 1997, EPA promulgated a revised 8 - hour ozone NAAQS (62 FR 38856 ) and a new PM 2.5 NAAQS (62 FR 38652) . The revised ozone NAAQS is based on 8 - hour average concentrations. T he 8 - hour averaging period replaced the previous 1 - hour averaging period, and4

the l evel of the NAAQS was changed f r o m 0.12 parts per million (ppm) to 0.08 ppm. The new PM 2.5 NAAQS established a health - based standard of 15.0 micrograms per cubic meter (μg/m 3 ) based on a 3 - ye ar average of annual mean PM 2.5 concentrations, and a 24 - hour standard of 65 μg/m 3 based on a 3 - ye ar average of the 98 th percentile of 24 - hour concentrations. EPA strengthened the 24 - hour PM 2.5 NAAQS from 65 μg/m 3 to 35 μg/m 3 on October 17, 2006 (71 FR 61144). Section 110(a) of the CAA requires States to submit State Implementation Plans ( SI Ps ) that provide for the implementation, maintenanc e, and enforcement of new or revised NAAQS within three y ears following the promulgation of such NAAQS. InMarch of 2004, Earth j ustice initiated a lawsuit against EPA for failure to take action against States that had not made SI P submissions to meet the requirements of section s 110(a)(1 ) and (2) for the 1997 8 - hour ozone and PM 2.5 NAAQS, i.e., failure to make a “finding of failure to submit the required SI P 110(a) SI P elements .” On March 10, 2005, EPA entered into a Consent Decree with Earth j ustice that obligate d EPA to make official findings , in accordance with section 110(k)(1) of the CAA as to whether States have made complete SI P submissions , pursuant to sections 110(a)(1) and (2), by December 15, 2007 for the 1997 8 - hour ozone NAAQS , and by October 5 , 2008 for the 1997 PM 2.5 NAAQS . EPA made completeness findings for the 1997 8 - hour ozone NAAQS on March 27, 2008 (73 FR 1620 5 ) and on October 22, 2008 (73 FR 62902) for the 1997 PM 2.5 NAAQS. These completeness findings did not include findings relating to: 1 ) section 110(a)(2)(C) to the extent that such subsection refers to a permit program as required by Part D Title Iof the CAA; 2 ) section 110(a)(2)(I ); and 3 ) section 110(a)(2)(D)(i) , which has been addressed by a separate5

finding issued by

EPA on April 25, 2005 (70 FR 21147) . Therefore, this action does not cover these specific elements. II. Summary of S tate Submittal The District provided multiple submittals to satisfy sectio n 110(a)(2) requirements, that are the subject of this proposed rule for the 1997 8 - hour ozone NAAQS and the 1997 and 2006 PM 2.5 NAAQS. The s ubmittals dated December 6, 2007 and January 11, 2008 addressed the 110(a)(2) requirements for the 1997 8 - hour ozo ne NAAQS ; the s ubmittals dated August 2 5 , 2008 and September 22, 2008 addressed the 110(a)(2) requirements for the 1997 PM 2.5 NAAQS ; and the submi t tal dated September 21, 2009 addressed the section 110 (a) (2) requirements for the 2006 PM 2.5 NAAQS . These s ubmittals addressed the following infrastructure elements, that are the subject of this proposed rule: 110(a)(2)(A), (B), (C), (D)(ii), (E), (F), (G), (H), (J), (K), (L), and (M).

EPA has analy

zed the above identified s ubmissions and is proposing to make a determination that such submittals meet the requirements of 110(a)(2)(A), (B), (C), (D)(ii), (E), (F), (G), (H), (J), (K), (L ), and (M). A detailed summary of EPA’s review of and rationale for approving the District’s submittals may be found in the Technical Support Document (TSD) for this action which is available on line at www.regulations.gov , Docket number EPA - R03 - OAR - 2010 - 0139 . III. Proposed Action EPA is proposing to approve the District of Columbia ’s submittals that provide the basic6

program elements specified in the CAA section s 110(a)(2)(A), (B ), (C), (D)(ii), (E), (F), (G), (H), (J), (K), (L ), and (M) necessary to implement, maintain, and enforce the 1997 8 - hour ozone and PM 2.5 NAAQS and the 2006 PM 2.5 NAAQS . EPA is soliciting public comments on the issu es discussed in this document. These co mments will be considered before taking final action.

IV. Statutory and Executive Order Reviews Under the CAA , the Administrator is required to approve a SI P submission that complies with the provisions of the CAA and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, i n reviewing SI P submissions, EPA’s role is to approve state choices, provided that they meet the criteria of the CAA . Accordingly , this action merely proposes to approve state law as meeting Federal requiremen ts and does not impose additional requirements beyond those imposed by

state law. For that reason, this proposed action:

 is not a "significant regulatory action” subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 5 1735, 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 unde r 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 (Public L aw 104 - 4) ;7

 d oes 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 regu latory 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 woul d be inc onsistent with the CAA ; 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 (5 9 FR 7629, February 16, 1994).8

Inaddition, this pro p osed rule , pertaining to the District of Columbia ’s section 110(a)(2) infrastructure requirements for the 1997 8 - hour ozone and PM 2.5 NAAQS and the 2006 PM 2.5 NAAQS , does not have tribal implic ations as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SI P 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.
