[AD-FRL-3855-7]

Preparation, Adoption, and Submittal

of State Implementation Plans;

Corrections to PM-10 Areas of

Concern

AGENCY: Environmental Protection

Agency (EPA).

ACTION: Technical corrections to the

areas of concern for certain Group I and

II areas.

SUMMARY: The EPA published national

ambient air quality standards (NAAQS)

and implementation policies for

particulate matter (PM] with an

aerodynamic diameter of a nominal 10

microns or less (PM-Ia) on July 1, 1987

(52 FR 24634 and 52 FR 24672). A notice

identifying areas with very high

probabilities (Group I) and moderate

probabilities (Group II) of violating the

PM-10 standards was published on

August 7, 1987 (52 FR 29383). A notice

that the grouping of three of these areas

had been modified was published on

March 28, 1989 (54 FR 12620). Work to

develop State implementation plans

(SIP's) to attain the PM-10 NAAQS

began immediately for the Group I

areas. Ambient PM-10 concentrations

have been monitored in the Group II

areas since 1987.

The EPA is, by this notice, clarifying

the descriptions of certain Group land

Group II areas of concern listed in the

August 7, 1987 notice. This action is

being taken because the areas were only

generally described in 1987 as cities,

counties, or planning areas. The States

were given guidance in the PM-IO SIP

Development Guideline (EPA-450/2-86--

002, June 1987) on how to further define

the extent of areas violating the PM-10

standards in the process of developing

PM-10 SIP's. Therefore, some States

have provided EPA with more detailed

descriptions of certain Group I and

Group II areas of concern.

DATES: These corrections are effective

October 31, 1990.

ADDRESSES: Information supporting the

Group'I and Group II area descriptions

can be obtained from the respective

EPA Regional Office which services that

particular State. The addresses of the

SUPPLEMENTARY INFORMATION:

1. Background

On July 1, 1987, the EPA promulgated

revised NAAQS for PM (52 FR 24634).

The standards incorporate a new

indicator of PM that includes only those

particles with an aerodynamic diameter

less than or equal to a nominal 10

microns.

Simultaneously, EPA published

revised requirements for SIP's to attain

and maintain the standards (52 FR

24672). In order to focus Federal and

State resources on implementing the

PM-la NAAQS first in those areas of

the country believed to be violating the

standards, EPA classified all areas of

the Nation into one of three groups.

Group I areas were those having a very

high probability of violating the PM-10

standards based on ambient air quality

data available for 1984 through 1987 for

PM-10 and total suspended PM. Group 1I

areas had a moderate probability of

violating the standards, and Group III

areas were those believed to be

currently attaining the standards.

A list of Group I and II areas in each

State was published in the Federal

Register on August 7, 1987 (52 FR 29383).

The remaining portion of any State not

listed as Group I or II in the August 7

notice was classified in Group III.

A subsequent notice, published on

March 28, 1989 (54 FR 12620), announced

that three revisions had been made to

the list of Group I and II areas.

Sandpoint, Idaho, was changed from

Group I to Group II, effective August 31,

1987 following a determination that the

area lacked sufficient ambient data to

justify a Group I classification. Porter

County, Indiana, was changed from

Group I to Group II, effective November

29,1988 as a result of a settlement

agreement negotiated with Bethlehem

Steel Corporation (see Bethlehem Steel

Corporation v. Thomas), 87-2476 (7th

Cir.). Mono Basin, California, was

changed from Group III to Group II,

effective June 8, 1988 following review of

the information used for the initial

classification.

2. Today's Action

The EPA is, by this notice, providing

technical corrections to clarify the

descriptions of several Group I and II

areas of concern. The EPA described the

areas of concern generally as cities,

towns, counties, or planning areas in the

August 7, 1987 notice and stated that

these descriptions were only initial

definitions of the areas to be

investigated in the PM-10 SIP

development process. The EPA had

previously provided guidance on

procedures for determining the

boundaries of areas not attaining the

standards in section 2.5 of the PM-10

SIP Development Guideline and in

section 6.3 of Procedures for Estimating

Probability of Nonattainment of a PM10 NAAQS Using Total Suspended

Particulate or PM-10 Data, EPA-450/4-

86-017, December 1986.

State air pollution control agencies, in

developing SIP's for Group I and certain

Group II areas over the past 3 years,

have been collecting data on source

emissions and ambient PM-10

concentrations, identifying control

measures, and predicting future PM-10

concentrations using dispersion models.

Consequently, EPA can now more

clearly define the extent of certain
