Nonattainment Areas and Determination Regarding Applicability of

Certain Reasonable Further Progress and Attainment Demonstration

Requirements

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The EPA proposes to determine that the Pittsburgh-Beaver

Valley and Reading ozone nonattainment areas have attained the National

Ambient Air Quality Standard (NAAQS) for ozone and that certain

reasonable further progress and attainment demonstration requirements,

along with certain related requirements, of Part D of Title I of the

Clean Air Act are not applicable for so long as these areas continue to

attain the ozone standard. In the final rules section of this Federal

Register, EPA is making these determinations without prior proposal. A

detailed rationale for the action is set forth in the direct final

rule. If no adverse comments are received in response to that direct

final rule, no further activity is contemplated in relation to this

proposed rule. If EPA receives adverse comments, EPA will withdraw the

direct final rule and address the comments in a subsequent final rule

based on this proposed rule. EPA will not institute a second comment

period on this notice. Any parties interested in commenting on this

notice should do so at this time.

DATES: Comments must be received in writing by June 26, 1995.
