Discussion of Regulations 

The International Bay City River Roar 

will be conducted on the Saginaw River 

between the Liberty Bridge and ye 

Veterans Memorial Bridge on the 12th. 

13th. and 14th of Jdy 1991. This event 

will have an estimated 70 hydroplanes 

which could pose hazards to navigation 

in the ma. Any vessel desiring to 

transit the regulated area may do so only with prior approval of the Patrol 

Commander [OEficer in Charge, U.S. 

Coast Guard Station Saginaw River. 

MI.). 

Economic Assessment and Certification 

This regulation is considered to be 

non-major under Executive Order 12291 on Federal Regulation and 

nonsknificant under Devartment of 

~ransiortation regulatory policies and 

procedures (44 FR 11034; February 20, 

1979). The economic impact has been 

found to be so minimal that a full 

regulatory evaluation is unnecessary. 

This event will draw a large number,of 

spectator craft into the area for the 

duration of the event. This should have 

a favorable impact on commercial 

facilities providing services to the 

spectators. Any impact on commercial 

traffic in the area will be negligible. 

Since the impact of this regulation is 

expected to be minimal, the Coast 

Guard certifies that it will not have a 

significant economic impact on a substantial number of small entities. 

Federalism 

This action has been analyzed in 

accordance with the principles and 

criteria contained in Executive Order 

12612, and it has been determined that 

this rulemaking does not have sufficient 

federalism implications to warrant the 

preparation of a Federalism 

Assessment.

SUPPLEMENTARY INFORMATION: 

I. Background 

A. 1887 Revision of the NAAQS for 

Purticulute Matter 

On July 1,1987, EPA revised the 

NAAQs for particulate matter, replacinn 

total s;speded particulates (TSP] as - 

the indicator for articulate 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-lo"] (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 atlainment of the PM-10 

NAAQS was possible and existing SIP'S 

needed less adjustment were placed in 

Group 11. (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 111 (52 FR 24672, 

24679-246821, 

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 I1 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 I1 was placed in Group 111 (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 11; Mono 

Basin. California, was changed from 

Group I11 to Group 11; and Sandpoint, 

Idaho, was changed from Group I to 

Group 11. 

On October 31,1990, EPA published 

technical corrections clarifying the 

boundaries of concern for some of the areas previously identified as Groups I 

and I1 areas (55 FR 45799). When EPA . 

listed the initial groupings for areas in 

the August 1987 notice, the Groups I and 

I1 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 I1 areas announced in October 1990 

specifically defined and delineated the 

boundaries of the Groups I and Group I1 

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 I1 

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.l 

11. Today's Action 

In the 1990 Amendments to the Clean 

Air Act. Coneress used the PM-10 

scheme as the starting point for 

desinnating areas on nonattainment and 

unc&ssifi&le for PM-10 by operalion of. 

law upon enactment of the 

Amendments. Group I areas identified in 

52 FR 29383 (August 7,1987) and as 

subsequently clarified in 55 FR 45799 

(October 31,19901 were designated 

nonattainment for PM-10 by operation 

of law [see section 107(d)(4)(B](i) of 

the amended Act]. Any other area (i.e.. 

Group I1 or 111 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 Isee 

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][ili) ofthe amended 

Act]. By this notice, EPA is announcing, 

as required by section 1W(d)(2) of the 

amended Act, all of those areas that 

were designated nonattainment for PM10 by operation of law on November 15. 

1990. 

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 the 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-IO 

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 

I Footnote 4 of the Odober 31.1990 notice 

references Gmup I1 areas with vio)alions of the PM- 10 NAAQS. 

2 The notice publiehed on October 31,1WfI[55 FR 

45799) reflects the revisions announced in the notice 

published on March 28.1989 (54 FR 12620). 

Heinonline -- 56 Fed. Reg. 11102 1991 
Federal Register / Vol. 56, No. 51 / Friday, March 15, 1991 / Rules and Regulations 11103 

the new PM-10 nonattainment areas 

proceeds in a timely fashion. Neither of these actions is subject to 

the APA requirements for notice-andcomment rulemaking [5 U.S.C. 55-57] 

or section 307(d) of the amended Clean 

Air Actq3 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 nonattninment 

for PM-10 by operation of law under 

section 107[d)(4)@) from the notice-andcomment procedural requirements of the 

APA. 

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 provislons of section 

172(a)(l)(B) pertaining to lack of notice 

and comment and judicial review shall 

apply when the Administrator 

announces these classifications. Section 

172(a)[l)(B), in turn, expressly exempts 

the classification announcement from 

the notice-and-comment procedures set 

forth in 5 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 

1W[d)(2) and lffl(a)J wiU 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. 

111. Initial PM-I0 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.

By November 15,1991, States must 

adopt and submit ta 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 1 of the 

Clean Air Act as amended (section 

18911. 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)[l) 

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
