40 CFR Part 81 Designations and Classifications for Initial PM-10 Nonattainment Areas

[AD-FRL-3913-12]
56 FR 11101 March 15, 1991

ACTION: Notice announcing designations and classifications for initial PM-10 nonattainment areas.

SUMMARY: Under section 107(d)(4)(B) of the Clean Air Act (Act) as amended by the Clean Air Act Amendments of 1990 (Pub. L. No. 101-549, November 15, 1990), certain areas were designated as nonattainment for the pollutant PM-10 by operation of law upon enactment of the Amendments. These areas include "Group" I areas identified at52 FR 29383 (August 7, 1987) and as subsequently clarified at55 FR 45799 (October 31, 1990). Other areas (i.e., Group II or III areas) containing sites for which air quality monitoring data showed a violation of the national ambient air quality standards (NAAQS) for PM-10 prior to January 1, 1989 were also designated nonattainment for PM-10 by operation of law upon enactment. All other areas were designated unclassified for PM-10 by operation of law. By this notice, EPA is announcing, as required by section 107(d)(2) of the amended Act, all of those areas that were designated nonattainment for PM-10 by operation of law on November 15, 1990. By this notice, EPA is also announcing, as required by section 188(a) of the amended Act, that all of the areas designated nonattainment for PM-10 by operation of law upon enactment of the Amendments were classified as moderate nonattainment areas at that time. In accordance with section 189(a)(2), States must submit State implementation plans (SIP's) for these areas by November 15, 1991.

DATES: Written comments on this notice must be received by April 15, 1991 at the address below. EFFECTIVE DATE: These actions will become effective on May 14, 1991.

ADDRESSES: Written comments on this action should be addressed to Larry D.

TEXT: SUPPLEMENTARY INFORMATION:

I. Background

A. 1987 Revision of the NAAQS for Particulate Matter On July 1, 1987, EPA revised the NAAQs for particulate matter, replacing total suspended particulates (TSP) as the indicator for particulate matter with a new indicator that included only those particles with an aerodynamic diameter less than or equal to a nominal 10 micrometers (called "PM-10") (52 FR 24634). At the same time, EPA set forth regulations for implementing the revised particulate matter standards and announced EPA's SIP development policy on PM-10 control strategies necessary to assure attainment and maintenance of the PM-10 NAAQS (see generally 52 FR 24672). The EPA adopted a PM-10 SIP development policy dividing all areas of the country into three categories based on their probability of violating the new NAAQS: (1) Areas with a strong likelihood of violating the PM-10 NAAQS and requiring substantial SIP adjustment were placed in Group I, (2) areas where attainment of the PM-10 NAAQS was Page 2 56 FR 11101possible and existing SIP's needed less adjustment were placed in Group II, (3) areas with a strong likelihood of

attaining the PM-10 NAAQS and therefore needing adjustment only to their preconstruction review program and monitoring network were placed in Group III (52 FR 24672, 24679-24682).

B. Prior Listing of and Modification to PM-10 Groups I, II, and III Areas In accordance with the standards, policies, and regulations published on July 1, 1987 for revising and implementing the new particulate matter standards, EPA identified and listed the Group I and Group II areas in each State in a notice published on August 7, 1987 (52 FR 29383). That notice also indicated that any area of the country not listed as Group I or II was placed in Group III (52 FR 29383). The EPA subsequently modified the listing for three areas and announced these revisions in a notice published on March 28, 1989 (54 FR 12620). Specifically, the 1989 notice indicated that Porter County, Indiana, was changed from Group I to Group II; Mono Basin, California, was changed from Group III to Group II; and Sandpoint, Idaho, was changed from Group I to Group II. On October 31, 1990, EPA published technical corrections clarifying the boundaries of concern for some of the areas previously identified as Groups I and II areas (55 FR 45799). When EPA listed the initial groupings for areas in the August 1987 notice, the Groups I and II areas of concern were generally described as cities, towns, counties, or planning areas. The EPA indicated at that time that these descriptions were only the initial definitions of the areas to be investigated in the SIP development process and would be better defined later. The clarifications to the Groups I and II areas announced in October 1990 specifically defined and delineated the boundaries of the Groups I and Group II areas in question based on information obtained in the SIP development process and EPA guidelines and procedures for determining particulate matter boundaries. With respect to Group II areas, the October 1990 notice also set forth those areas containing a site for which air quality monitoring data showed a violation of the NAAQS prior to January 1, 1989. n1
n 1 Footnote 4 of the October 31, 1990 notice references Group II areas with violations of the PM-10 NAAQS.

II. Today's Action In the 1990 Amendments to the Clean Air Act, Congress used the PM-10 grouping scheme as the starting point for designating areas on nonattainment and unclassifiable for PM-10 by operation of law upon enactment of the Amendments. Group I areas identified in52 FR 29383 (August 7, 1987) and as subsequently clarified in55 FR 45799 (October 31, 1990) were designated nonattainment for PM-10 by operation of law n2 [see section 107(d)(4)(B)(i) of the amended Act]. Any other area (i.e., Group II or III areas) containing a site for which air quality monitoring data showed a violation of the NAAQS for PM-10 prior to January 1, 1989 was also designated nonattainment for PM-10 by operation of law upon enactment [see 107(d)(4)(B)(ii) of the amendment Act]. All other areas were designated unclassifiable for PM-10 by operation of law [see 107(d)(4)(B)(iii) of the amended Act]. By this notice, EPA is announcing, as required by section 107(d)(2) of the amended Act, all of those areas that were designated nonattainment for PM-10 by operation of law on November 15, 1990.

n 2 The notice published on October 31, 1990 (55 FR 45799) reflects the revisions announced in the notice published on March 28, 1989 (54 FR 12620). Section 188(a) of the amended Act provides that those areas designated nonattainment for PM-10 upon enactment of the 1990 Clean Air Act Amendments were, by operation of law, classified as moderate PM-10 nonattainment areas at Page 3 56 FR 11101the time of their designation as nonattainment. By this notice, EPA is also announcing, as required by section 188(a) of

the amended Act, that all of the areas designated as nonattainment for PM-10 by operation of law upon enactment of the Amendments were classified as moderate nonattainment areas at that time. For administrative efficiency reasons, EPA will defer the ministerial act of formally codifying these PM-10 designations and classifications in 40 CFR part 81 until EPA codifies designations and classifications for other pollutants sometime within the next few months. This notice is provided now in order to make the announcements required by sections 107(d)(2) and 188(a) of the revised Act and to ensure that SIP development for the new PM-10 nonattainment areas proceeds in a timely fashion. Neither of these actions is subject to the APA requirements for notice-and-comment rulemaking (5 U.S.C. 553-557) or section 307(d) of the amended Clean Air Act. n3 Regarding designations, section 107(d)(2) of the amended Act requires the Administrator to publish a notice announcing designations occurring pursuant to section 107(d)(4), but explicitly provides that such announcement is not subject to APA notice-and-comment rulemaking procedures. Thus, Congress has expressly exempted the announcement of those areas designated nonattainment for PM-10 by operation of law under section 107(d)(4)(B) from the notice-and-comment procedural requirements of the APA.

n 3 Regarding section 307(d) requirements, today's actions are not among the actions listed in section 307(d)(1) of the amended Act as being subject to the procedural requirements of section 307(d), nor has the Administrator designated these actions as 307(d)(1)(U) of the amended Act. Regarding classifications, section 188(a) of the amended Act requires the Administrator to publish a notice announcing the classifications of these areas. Section 188(a) explicitly states that the provisions of section 172(a)(1)(B) pertaining to lack of notice and comment and judicial review shall apply when the Administrator announces these classifications. Section 172(a)(1)(B), in turn, expressly exempts the classification announcement from the notice-and-comment procedures set forth in5 U.S.C. 553-557 of the APA. Nevertheless, for the purpose of providing an opportunity for public participation and avoiding error, EPA will entertain any comments on these actions that are received by April 15, 1991. The EPA's announcement of these actions [for purposes of sections 107(d)(2) and 188(a)] will become effective on May 14, 1991. This will provide enough time for EPA to make any adjustments to the announcement that are appropriate in light of the comments.

III. Initial PM-10 Nonattainment Areas The following list identifies all of those areas designated as nonattainment for PM-10 on November 15, 1990, upon enactment of the Clean Air Act Amendments of 1990. The EPA also announces, pursuant to section 188(a) of the amended Act, that all of these areas were classified as moderate by operation of law upon enactment of the Amendments.

1 When cities or towns are shown, the area of concern is defined by the municipal boundary limits as of the Page 10 56 FR 11101date of this notice. 2 When a planning area is shown, the area of concern includes the entire planning area unless the area is further defined (e.g., by township, range, and/or section).

IV. Significance of Today's Action By November 15, 1991, States must adopt and submit to EPA a SIP for all those areas that were classified as moderate PM-10 nonattainment areas by operation of law upon enactment of the 1990 Clean Air Act Amendments [see Subpart 4 of Part D of Title I of the Clean Air Act as amended (section 189)]. All of the areas listed above must submit a SIP meeting the general requirements for nonattainment areas identified in section 172 of the amended Act and the requirements specific to PM-10 in Subpart 4 of Part D. In particular, section 189(a) of the amended Act requires that all of the initial moderate PM-10 nonattainment areas submit a SIP by November 15, 1991 which includes the following: 1. Either a demonstration (including air quality modeling) that the plan will provide for attainment by December 31, 1994 or a demonstration that attainment by that date is impracticable. 2. Provisions to assure that reasonably available control measures (including reasonably available control technology) for the control of PM-10 are implemented by December 10, 1993. In addition, a new source permit program meeting the requirements of Part D of the Act is required for the construction and operation of new and modified major stationary sources of PM-10 (including, in some cases, PM-10 precursors). A SIP revision meeting this requirement is due by June 30, 1992 for all of the initial moderate PM-10 nonattainment areas. The EPA will provide additional guidance on SIP requirements for these areas in the near future. Also note that EPA must take final action by the end of 1991 with respect to which of these initial PM-10 nonattainment areas should be reclassified from moderate to serious because they cannot practicably attain the PM-10 air quality standards by December 31, 1994 [see section 188(b)(1) of the amended Act]. If reclassified as serious, these areas will be subject to additional control requirements and a new attainment date. Since EPA must propose these reclassifications by June 30, 1991, EPA will work with the States before that date in order to develop a proposed list of moderate areas to be reclassified as serious.

V. Authority Sections 107(d)(4), 110, 188(a), and 301 of the amended Clean Air Act provide authority for today's action. Dated: March 7, 1991.
