40 CFR Part 52

[PA 133-4087b; FRL-6355-1]

Approval and Promulgation of Air Quality Implementation Plans;

Commonwealth of Pennsylvania; Motor Vehicle Inspection and Maintenance

Program

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve the latest revision to the

Pennsylvania State Implementation Plan (SIP) consisting of the plan the

Commonwealth will use to conduct the ongoing evaluation of its enhanced

inspection and maintenance (I/M) program. With the submission of this

program evaluation plan, Pennsylvania has remedied all conditions that

EPA had placed upon approval of the Commonwealth's enhanced I/M

program. Therefore, EPA is today also proposing to convert its

conditional approval of Pennsylvania's enhanced I/M program SIP

revisions to full approval, in accordance with the requirements of the

Clean Air Act. In the ``Rules and Regulations'' section of this Federal

Register, EPA is both approving the SIP submittal and converting its

conditional approval to a full approval as a direct final rule without

prior proposal because the Agency views this as a noncontroversial

submittal and anticipates no adverse comments. A detailed rationale for

the approval is set forth in the direct final rule. Details of EPA's

evaluation of the Commonwealth's SIP revisions are included in a

technical support document (TSD) prepared in support of this rulemaking

action. A copy of the TSD is available, upon request, from the EPA

Regional Office listed in the ADDRESSES section of this document. If

EPA receives no adverse comments, EPA will not take further action on

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

the direct final rule and it will not take effect. EPA will address all

public comments 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 July 19, 1999.

ADDRESSES: Written comments must be addressed and sent in hard copy to
