Clean Air Act Promulgation of Extension of Attainment Date for

the Pittsburgh-Beaver Valley Moderate Ozone Nonattainment Area;

Pennsylvania

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA proposes to extend the attainment date for the Pittsburgh-

Beaver County moderate ozone nonattainment area in Pennsylvania to

November 15, 1997. This extension is based in part on monitored air

quality readings for the national ambient air quality standard (NAAQS)

for ozone during 1996. Accordingly, EPA proposes to update the table in

40 CFR part 81 concerning attainment dates in the State of

Pennsylvania. A detailed rationale for the approval is set forth in the

direct final rule and accompanying technical support document. If no

adverse comments are received in response to this proposed rule, no

further activity is contemplated in relation to this rule. If EPA

receives adverse comments, the direct final rule will be withdrawn and

all public comments received will be addressed in a subsequent final

rule based on this proposed rule.

EPA will not institute a second comment period on this action. Any

parties interested in commenting on this action should do so at this

time.

DATES: Comments must be received in writing by March 27, 1997.

ADDRESSES: Written comments may be mailed to Marcia L. Spink, Associate

Director, Air Programs, Mailcode 3AT00, U.S. Environmental Protection

Agency, Region III, 841 Chestnut Building, Philadelphia, Pennsylvania
