# SUPPLEMENTARY INFORMATION:

## I. Background

                    On July 18, 1997, EPA promulgated a revised 8-hour ozone NAAQS (62 FR 38856) and a new PM2.5                     NAAQS (62 FR 38652). The revised ozone NAAQS is based on 8-hour average concentrations. The 8-hour averaging period 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. The new PM2.5                     NAAQS established a health-based standard of 15.0 micrograms per cubic meter (µg/m3                    ) based on a 3-year average of annual mean PM2.5                     concentrations, and a 24-hour standard of 65 µg/m3                     based on a 3-year average of the 98th percentile of 24-hour concentrations. EPA strengthened the 24-hour PM2.5                     NAAQS from 65 µg/m3                     to 35 µg/m3                     on October 17, 2006 (71 FR 61144).                

                    Section 110(a) of the CAA requires States to submit State Implementation Plans (SIPs) that provide for the implementation, maintenance, and enforcement of new or revised NAAQS within three years following the promulgation of such NAAQS. In March of 2004, Earthjustice initiated a lawsuit against EPA for failure to take action against States that had not made SIP submissions to meet the requirements of sections 110(a)(1) and (2) for the 1997 8-hour ozone and PM2.5                     NAAQS, i.e., failure to make a “finding of failure to submit the required SIP 110(a) SIP elements.” On March 10, 2005, EPA entered into a Consent Decree with Earthjustice that obligated EPA to make official findings, in accordance with section 110(k)(1) of the CAA as to whether States have made complete SIP 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 PM2.5                     NAAQS. EPA made completeness findings for the 1997 8-hour ozone NAAQS on March 27, 2008 (73 FR 16205) and on October 22, 2008 (73 FR 62902) for the 1997 PM2.5                     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 I of the CAA; (2) section 110(a)(2)(I); and (3) section 110(a)(2)(D)(i), which has been addressed by a separate finding issued by EPA on April 25, 2005 (70 FR 21147). Therefore, this action does not cover these specific elements.                

## II. Summary of State Submittal

                    The District provided multiple submittals to satisfy section 110(a)(2) requirements, that are the subject of this proposed rule for the 1997 8-hour ozone NAAQS and the 1997 and 2006 PM2.5                     NAAQS. The submittals dated December 6, 2007 and January 11, 2008 addressed the 110(a)(2) requirements for the 1997 8-hour ozone NAAQS; the submittals dated August 25, 2008 and September 22, 2008 addressed the 110(a)(2) requirements for the 1997 PM2.5                     NAAQS; and the submittal dated September 21, 2009 addressed the section 110(a)(2) requirements for the 2006 PM2.5                     NAAQS. These submittals 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 analyzed the above identified submissions 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                     *http://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 basic program elements specified in the CAA sections 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 PM2.5                     NAAQS and the 2006 PM2.5                     NAAQS. EPA is soliciting public comments on the issues discussed in this document. These comments will be considered before taking final action.                

## IV. Statutory and Executive Order Reviews

Under the CAA, the Administrator is required to approve a SIP 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, in reviewing SIP 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 requirements 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 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 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  ( 59 FR 7629 , February 16, 1994).

                    In addition, this proposed rule, pertaining to the District of Columbia's section 110(a)(2) infrastructure requirements for the 1997 8-hour ozone and PM2.5                     NAAQS and the 2006 PM2.5                     NAAQS, does not have Tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not approved                           ( print page 27514)                        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.
