Approval and Promulgation of Air Quality Implementation Plans;

Delaware, the District of Columbia, Maryland, Pennsylvania, Virginia;

Revisions to the State Implementation Plans (SIPs) Addressing Ozone

Monitoring

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA proposes to approve revisions to the following states

State Implementation Plans (SIPs) for ozone: Delaware, the District of

Columbia, Maryland, Pennsylvania, and Virginia. This action is based

upon revision requests submitted by these states to satisfy the

requirements of the Clean Air Act, as amended November 15, 1990 and the

Photochemical Assessment Monitoring Stations (PAMS) regulations. The

PAMS regulation required states to provide for the establishment and

maintenance of an enhanced ambient air quality network in the form of

PAMS by November 12, 1993.

In the Final Rules section of this Federal Register, EPA is

approving these states' SIP revisions as a direct final rule without

prior proposal because the Agency views these as noncontroversial SIP

revisions and anticipates no adverse comments. A detailed rationale for

the approval is set forth in the direct final rule. 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adverse comments, the direct final rule will be withdrawn and all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 October 11, 1995.

ADDRESSES: Written comments on this action should be addressed to
