## ENVIRONMENTAL PROTECTION AGENCY 40 CFR Part 51 [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 ofconcern for certain Group I and IIareas. SUMMARY: The EPA published national ambient air quality standards (NAAQS) and implementation policiesfor particulate matter (PM] with an aerodynamic diameter ofa nominal 10 microns or less (PM-Ia) on July 1, 1987 

## (52 FR 24634 and 52 FR 24672). Anotice identifying areas with very high probabilities (Group I)and moderate probabilities (Group II) ofviolating the PM-10 standards was published on August 7, 1987 (52 FR 29383). A notice that the grouping ofthree ofthese 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 thisnotice, clarifying the descriptions ofcertain Group land Group II areas ofconcern listed in the August 7, 1987 notice. This action is being taken because the areas were only generally described in 1987 as cities, counties, orplanning 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 ofareas violating the PM-10 standards in the process ofdeveloping PM-10 SIP's.Therefore, some States have provided EPA with more detailed descriptions ofcertain Group I and Group IIareas ofconcern. DATES: 

## These corrections are effective October 31, 1990. ADDRESSES:

## 1. Background

On July 1, 1987, theEPA promulgated revised NAAQS for PM (52FR 24634). The standards incorporate a new indicator ofPM that includes onlythose particles with an aerodynamic diameter less than orequal to a nominal 10 microns.

Simultaneously, EPA published revised requirements for SIP'sto attain and maintain the standards (52FR 24672). In orderto 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 ofviolating 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 listof 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 IorII 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 ofGroup Iand 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 Iclassification. Porter County, Indiana, was changed from Group I to Group II,effective November 29,1988 as a result ofa settlement agreement negotiated with Bethlehem Steel Corporation (see BethlehemSteel Corporationv. 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 ofseveral Group I and II areas ofconcern. The EPA described the areas ofconcern generally as cities, towns, counties, or planning areas in the August 7, 1987notice and stated that these descriptions were only initial definitions ofthe areas to be investigated in the PM-10 SIP development process. The EPA had previously provided guidance on procedures fordetermining the boundaries ofareas not attaining the standards in section 2.5 of the PM-10 SIPDevelopment Guideline and in section 6.3 ofProcedures for Estimating Probability ofNonattainment ofa PM10 NAAQS Using Total Suspended Particulate orPM-10 Data,EPA-450/4- 86-017, December 1986.

State air pollution control agencies, in developing SIP's for Group Iand 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 ofcertain
