### Guard DistrictLegal Office. Discussion of Regulations

The International Bay City River Roar will be conductedon the Saginaw River between the LibertyBridge and the 

### Veterans Memorial Bridge on the 12th, 13th, and 14th ofJuly 1991. This event will have an estimated 70hydroplanes which could posehazards to navigation in thearea. Any vessel desiring to transit the regulated areamay do so onlywith prior approvalofthe Patrol Commander (Officer in Charge, U.S. Coast Guard Station Saginaw River, MI.). Economic Assessment and Certification



### This regulation is considered to be non-majorunder Executive Order 12291 on Federal Regulation and 

### nonsignificant under Department of Transportation regulatory policies and procedures (44FR 11034; February 26, 

### 1979). The economic impacthas been found tobe so minimal that afull regulatory evaluation is unnecessary. This eventwilldraw a largenumber of spectator craft into the areafor the duration ofthe event.This should have afavorable impact on commercial facilities providing servicesto the spectators. Any impact on commercial traffic in thearea will be negligible.

Since the impact ofthis regulation is expected tobe minimal, the Coast Guard certifies that it will nothave a significant economic impact on a substantialnumber ofsmall entities.

AGENCY 40 CFR Part81 [AD-FRL-3913-12] Designations and Classifications for Initial PM-10 Nonattainment Areas AGENCY: Environmental Protection Agency (EPA). 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 ActAmendments of 1990 (Pub.L. No. 101-549, November 15, 1990), certain areas were designated as nonattainment for thepollutant PM-10 by operation oflaw upon enactment of the Amendments. These areas include "Group" I areas identified at 52 FR 29383 (August 7, 1987) and as subsequently clarified at 55 FR 45799 (October 31, 1990). Other areas (i.e., Group II orIl areas) containing sitesfor which air quality monitoring data showed a violation ofthe nationalambient air quality standards (NAAQS) for PM-10 prior to January 1,1989were also designated nonattainment forPM-10 by operation oflaw upon enactment. All otherareas were designated unclassified forPM-10 by operation of law. By this notice, EPA is announcing, as required by section 107(d)(2) ofthe amended Act,all ofthose areas that
were designated nonattainment forPM10by operation of law on November 15, 1990.

By this notice, EPA isalso announcing, as required by section 188(a) ofthe amended Act, that all ofthe areas designated nonattainment for PM10 by operation of law upon enactment ofthe 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 byApril 15, 1991 at the address below. EFFECTIVE DATE: These actionswill become effective on May 14, 1991.

SUPPLEMENTARY INFORMATION: I. Background A. 1987RevisionoftheNAAQSfor Particulate Matter On July 1,1987, EPA revised the NAAQs forparticulate 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 orequal to a nominal 10 micrometers (called "PM-10")(52FR 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 ofthe PM-10NAAQS (see generally .52 FR 24672). The EPA adopted a PM-10 SIPdevelopment policy dividing all areas ofthe country into three categories based on their probability ofviolating the new NAAQS: (1)Areas with a strong likelihood ofviolating the PM-10 NAAQS and requiring substantial SIP adjustment were placed in Group I,(2)
areas where attainment ofthe PM-1 NAAQS was possible and existing SIP's needed less adjustment were placed in Group 

### II, (3)areas with a strong likelihood ofattaining the PM-10 NAAQS and therefore needing adjustment only to theirpreconstruction review program and monitoring network
were placed in Group III (52 FR 24672, 24679-24682). B.Prior ListingofandModificationto PM-la GroupsI,II,and IIIAreas In accordance with the standards, policies, and regulations published on July 1, 1987 forrevising and implementing the new particulate matter standards, EPA identified and listed the Group Iand Group IIareas in each State in a notice published on August 7, 1987 (52FR 29383). That notice also indicated that any area ofthe country not listed as Group I orIIwas placed in Group III (52 FR 29383).

The EPA subsequently modified the listing forthree 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, EPApublished technical corrections clarifying the boundaries ofconcern for some of the
areas previously identified as Groups I and II areas (55FR 45799). When EPA listed the initial groupings for areas in the August 1987 notice, the Groups I and II areas ofconcern 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 wouldbe better defined later.The clarifications to the Groups I and 1Iareas announced in October 1990 specifically defined and delineated the boundaries ofthe Groups I and Group II areas in question based on information obtained in the SIPdevelopment 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 theNAAQS prior to January 1, 1989.1
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 forPM-10 by operation of law upon enactment ofthe Amendments. Group Iareas identified in 52 FR 29383 

### (August 7, 1987) and as subsequently clarified in 55 FR 45799 (October 31, 1990)were designated nonattainment for PM-10 by operation 

### of law 2 [see section 

### 107(d)(4)(B)(i) of the amended Act]. Any other area (i.e., Group II orIII areas) containing a site for which air quality monitoring data showed a violation ofthe NAAQS for PM-la prior to January 1, 1989 was also designated nonattainment forPM-10 by operation oflaw upon enactment (see 107(d)(4)(B)(ii) of the amendment Act]. All other areas were designated unclassifiable forPM-10 by operation of law [see 107(d)(4)(B)(iii) ofthe amended Act]. By this notice, EPA is announcing,
as required by section 107(d)(2) of the amended Act, all ofthose areas that
were designated nonattainment forPM10 by operation oflaw on November 15, 1990.

Section 188(a) ofthe amended Act provides that those areas designated nonattainment for PM-10 upon enactment ofthe 1990 Clean Air Act Amendments were, by operation oflaw, classified as moderate PM-la nonattainment areas at the time oftheir designation as nonattainment. By this notice, EPA is also announcing, as required by section 188(a) ofthe amended Act, that all ofthe areas designated as nonattainment forPM-10 by operation oflaw upon enactment of' the Amendments were classified as moderate nonattainment areas at that time.

For administrative efficiency reasons, EPAwill 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. Thisnotice is provided
now in order to make the announcements required by sections 107(d)(2) and 188(a) ofthe revised Act and to ensure that SIPdevelopment for

IFootnote 4 ofthe October31, 1990 notice references Group 11areas with violations ofthe PM10 NAAQS.

2The notice published on October31, 1990155 FR 45799 reflects the revisions announced in the notice published on March 28, 1989 (54 FR 12620).

thenew PM-10 nonattainment areas proceeds in atimely fashion.

Neither ofthese actions is subject to the APA requirements fornotice-andcomment rulemaking 

### (5U.S.C. 553-557) 

### or section 307(d) ofthe amended Clean AirAct.3 

### Regarding designations. section 107(d)(2) oftheamended Act requires theAdministrator 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 ofthose areas designated nonattainment forPM-10 by operation oflaw under section 107(d)(4)(B from the notice-andcomment procedural requirements ofthe APA. Regarding classifications, section 188(a) ofthe amended Act requires the Administrator to publish a notice announcing the classifications of these
areas. Section 188(a) explicitly states that theprovisions ofsection 172(a)(1)(B) pertaining to lack ofnotice and comment andjudicial 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 in 5U.S.C. 553-557 ofthe APA.

Nevertheless, forthe purpose of providing an opportunity for public participation and avoiding error,EPA will entertain any comments on these actions thatare received by April 15, 1991. The EPA's announcement ofthese

PM-10 INITIAL NONATTAINMENT AREAS " actions [for purposes ofsections 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 ofthe comments. Ill.Initial PM-10 Nonattainment Areas

The following list identifies all of those areas designated as nonattainment forPM-10 on November 15, 1990,upon enactment ofthe Clean AirAct Amendments of 1990.The EPA also announces, pursuant to section 188(a) ofthe amended Act, that all of these areas were classified as moderate by operation oflaw upon enactment of the Amendments.

IV. Significance ofToday's Action

By November 15, 1991, States must adopt and submit to EPA a SIPfor all those areas that were classified as moderate PM-10 nonattainment areas by operation oflaw upon enactment of the 1990 Clean Air Act Amendments [see Subpart 4 ofPart D ofTitle I ofthe Clean Air Act as amended (section 189)]. All ofthe areas listed above must submit a SIPmeeting the general requirements for nonattainment areas identified in section 172 ofthe amended Act and the requirements specific to PM-10 in Subpart 4ofPart D. In particular, section 189(a) ofthe 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 ofPM-10 are implemented by December 10, 1993.

In addition, a new source permit program meeting the requirements of PartD ofthe Act is required for the construction and operation ofnew and modified major stationary sources of PM-10 (including,in some cases, PM-10 precursors). A SIPrevision meeting this requirement is due by June 30, 1992 for all ofthe initial moderate PM-10 nonattainment areas. TheEPA 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 of1991 with respect to which ofthese initial PM-10 nonattainment areas should be reclassified from moderate to serious because they cannot practicably attain the PM-1 air quality standards by December 31, 1994 [see section 188(b)(1) of the amended Act]. Ifreclassified as serious, these areas will be subject to additional control requirements and a new attainment date. Since EPAmust 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 ofthe amended Clean Air Act provide authority for today's action.
