Federal Register / Vol. 56, No. 51 / Friday, March 15, 1991 / Rules and Regulations

Lieutenant Commander, U.S. Coast

Guard, project attorney, Ninth Coast

Guard District Legal Office.

Discussion of Regulations

The International Bay City River Roar

will be conducted on the Saginaw River

between the Liberty Bridge and the

Veterans Memorial Bridge on the 12th,

13th, and 14th of July 1991. This event

will have an estimated 70 hydroplanes

which could pose hazards to navigation in the area. Any vessel desiring to

transit the regulated area may do so

only with prior approval of the Patrol

Commander (Officer 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

nonsignificant under Department of

Transportation regulatory policies and

procedures (44 FR 11034; February 26,

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.

List of Subjects in 33 CFR Part 100

Commander. The Patrol Commander

may be contacted on channel 16 (156.8

MHZ) by the call sign "Coast Guard

Patrol Commander". Any vessel, not

authorized to participate in the event,

desiring to transit the regulated area

may do so only with prior approval of

the Patrol Commander and when so

directed by that officer. Transiting

vessels will be operated at bare

steerageway, and will exercise a high

degree of caution in the area.

(4) The Patrol Commander may direct

the anchoring, mooring, or movement of

any boat or vessel within the regulated

area. A succession of sharp, short

signals by whistle or horn from vessels

patrolling the area under the direction of

the U.S. Coast Guard Patrol Commander

shall serve as a signal to stop. Any

vessel so signaled shall stop and shall

comply with the orders of the Patrol

Commander. Failure to do so may result

in expulsion from the area, citation for

failure to comply, or both.

(5) The Patrol Commander may

establish vessel size and speed

limitations, and operating conditions.

(6) The Patrol Commander may

restrict vessel operation within the

regulated area to vessels having

particular operating characteristics.

(7) The Patrol Commander may

terminate the marine event or the

operation of any vessel at any time it is

deemed necessary for the protection of

life and property.

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 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 at 52 FR 29383

(August 7, 1987) and as subsequently

clarified at 55 FR 45799 (October 31,

1990). Other areas (i.e., Group II or Il

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 PM10 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 PM10 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.

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-1

NAAQS was possible 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-la 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 1I 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, 1989.1

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 for PM-10 by operation 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, 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 or III areas) containing a site

for which air quality monitoring data

showed a violation of the NAAQS for

PM-la 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 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-la

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-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

I Footnote 4 of the October 31, 1990 notice

references Group 11 areas with violations of the PM10 NAAQS.

2 The notice published on October 31, 1990 155 FR

45799 reflects the revisions announced in the notice

published on March 28, 1989 (54 FR 12620).

11102

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

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. 553-557)

or section 307(d) of the amended Clean

Air Act.3 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-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 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 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

PM-10 INITIAL NONATTAINMENT AREAS "

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.

Ill. 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.

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-1 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.
