What Action Is EPA Taking? The Environmental Protection Agency (EPA) is approving the Limited Maintenance Plan (LMP) for the Municipality of Guaynabo nonattainment area (Guaynabo NAA). EPA is concurrently redesignating the Guaynabo NAA to attainment for the National Ambient Air Quality Standards (NAAQS) for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM10). For additional details on EPA's analysis and findings, the reader is referred to the proposal published in the September 2, 2009 
                    **Federal Register**
                     (74 FR 45387) and a more detailed discussion is contained in the Technical Support Document which is available on line at 
                    *www.regulations.gov,*
                     Docket number EPA-R02-OAR-2009-0508. II. What Is the Background for EPA's Action? As required by the Clean Air Act (Act), in 1987 the EPA revised the particulate matter NAAQS from total suspended particles to PM10. The standard was changed to better protect public health and the environment. The Act, as amended in 1990, required that all areas that have measured a violation of the NAAQS for PM10
                     before January 1, 1989 be designated nonattainment. On November 15, 1990 by operation of law, the Municipality of Guaynabo in Puerto Rico was designated nonattainment for PM10
                     and classified as moderate based on violations measured in 1987. On November 14, 1993 the Puerto Rico Environmental Quality Board (PREQB) submitted to EPA a State Implementation Plan (SIP) revision which consisted of a PM10
                     SIP for the Municipality of Guaynabo. The Guaynabo PM10
                     SIP revision was reviewed and approved by EPA on May 31, 1995 (60 FR 28333) and became effective on June 30, 1995. After completing the appropriate public notice and comment procedures, on March 31, 2009, the PREQB submitted to EPA a “Limited Maintenance Plan 24 Hour Particulate Matter (PM10) National Ambient Air Quality Standards and Redesignation Request for the Municipality of Guaynabo Moderate Nonattainment Area State Implementation Plan Revision.” On September 2, 2009 (74 FR 45387), EPA proposed to approve the LMP for the Municipality of Guaynabo and the request by the Commonwealth of Puerto Rico to redesignate the area from nonattainment to attainment for PM10. III. What Comments Were Received? No comments were received in response to the September 2, 2009 proposal. IV. What Are the Requirements for Redesignation? A. Clean Air Act Requirements for Redesignation of Nonattainment Areas Nonattainment areas can be redesignated to attainment after the area has measured air quality data showing it has attained the NAAQS and when certain planning requirements are met. Section 107(d)(3)(E) of the Act, and the General Preamble for the implementation of Title I of the Act (General Preamble) provide the criteria for redesignation. See 57 FR 13498 (April 16, 1992). These criteria are further clarified in a policy and guidance memorandum from John Calcagni, Director, Air Quality Management Division, EPA Office of Air Quality Planning and Standards dated September 4, 1992, “Procedures for Processing Requests to Redesignate Areas to Attainment”. The criteria for redesignation are: (1) The Administrator has determined that the area has attained the applicable NAAQS; (2) the Administrator has fully approved the applicable SIP for the area under section 110(k) of the Act; (3) the state containing the area has met all requirements applicable to the area under section 110 and part D of the Act; (4) the Administrator has determined that the improvement in air quality is due to permanent and enforceable reductions in emissions; and (5) the Administrator has fully approved a maintenance plan for the area as meeting the requirements of section 175A of the Act. B. The Limited Maintenance Plan (LMP) Option for PM*10*
                     Nonattainment Areas On August 9, 2001, EPA issued guidance on streamlined maintenance plan provisions for certain moderate PM10
                     nonattainment areas seeking redesignation to attainment (Memo from Lydia Wegman, Director, Air Quality Standards and Strategies Division, entitled “Limited Maintenance Plan Option for Moderate PM10
                     Nonattainment Areas,”) referred to as the LMP option memo. The LMP option memo contains a statistical demonstration that areas meeting certain air quality criteria will, with a high degree of probability, maintain the standard 10 years into the future. It follows that future year emission inventories for these areas, and some of the standard analyses to determine transportation conformity with the SIP, are no longer necessary. To qualify for the LMP option: (1) The area should have attained the PM10
                     NAAQS; (2) the average annual PM10
                     design value for the area, based upon the most recent 5 years of air quality data at all monitors in the area, should be at or below 40 micrograms per cubic meter (μg/m3
                    ); and (3) the 24 hour design value should be at or below 98 μg/m3
                    . If an area cannot meet this test, it may still be able to qualify for the LMP option if the average design value for the site is less 
                    ( print page 1545)
                    than the site-specific critical design values. In addition, the area should expect only limited growth in on-road motor vehicle PM10
                     emissions (including fugitive dust) and should have passed a motor vehicle regional emissions analysis test. The LMP option memo also identifies core provisions that must be included in the LMP. These provisions include an attainment year emissions inventory, assurance of continued operation of an EPA-approved air quality monitoring network, and contingency provisions. C. Conformity Under the Limited Maintenance Plan Option The transportation conformity rule and the general conformity rule (40 CFR part 93; also see 40 CFR part 51) apply to nonattainment areas and maintenance areas covered by an approved maintenance plan. Under either conformity rule, an acceptable method of demonstrating that a federal action conforms to the applicable SIP is to demonstrate that expected emissions from the planned action are consistent with the emissions budget for the area. While EPA's LMP option does not exempt an area from the need to affirm conformity, it explains that the area may demonstrate conformity without submitting an emissions budget. Under the LMP option, emissions budgets are treated as essentially not constraining for the length of the maintenance period because it is unreasonable to expect that the qualifying areas would experience so much growth in that period that a violation of the PM10
                     NAAQS would result. For transportation conformity purposes, EPA would conclude that emissions in these areas need not be capped for the maintenance period and therefore a regional emissions analysis would not be required. Similarly, Federal actions subject to the general conformity rule could be considered to satisfy the “budget test” specified in 40 CFR 93.158(a)(5)(i)(A) as these budgets also are essentially considered to be unlimited. V. What Are EPA's Conclusions? EPA has determined that the PM10
                     Limited Maintenance Plan submitted by the PREQB on March 31, 2009 for the Municipality of Guaynabo meets all Clean Air Act provisions and EPA policy and guidance, including the criteria outlined in EPA's LMP option memo. Therefore, EPA is approving the PM10
                     Limited Maintenance Plan for the Municipality of Guaynabo and all of its components as they were submitted by PREQB on March 31, 2009. Specifically, EPA is approving the 2002 PM10
                     attainment emissions inventory, attainment plan, maintenance demonstration, contingency measures, monitoring network, transportation conformity analysis and revisions to Rules 102 and 423 of the Puerto Rico Regulation for the Control of Atmospheric Pollution. EPA is also approving the redesignation request for the Municipality of Guaynabo submitted by the PREQB on March 31, 2009 based on EPA's determination that the supporting documentation for redesignation satisfies all Clean Air Act requirements and EPA's policy and guidance, including the criteria outlined in EPA's redesignation guidance memorandum. VI. 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 underExecutive 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 inExecutive Order 13132 (64 FR 43255, August 10, 1999);
                Is not an economically significant regulatory action based on health or safety risks subject toExecutive Order 13045 (62 FR 19885, April 23, 1997);
                Is not a significant regulatory action subject toExecutive 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, underExecutive 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 March 15, 2010. 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).) List of Subjects 40 CFR Part 52 Environmental protection
