ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[PA 122-4078b; FRL-6160-7]


Approval and Promulgation of Air Quality Implementation Plans; 
Commonwealth of Pennsylvania; Enhanced Motor Vehicle Inspection and 
Maintenance Program

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: This action proposes approval of the Commonwealth of 
Pennsylvania's August 21, 1998 submission to supplement its State 
Implementation Plan (SIP) revision for the enhanced motor vehicle 
emissions inspection and maintenance (I/M) program. The Commonwealth's 
August 1998 submission addresses seven minor, de minimus deficiencies. 
In addition, Pennsylvania submitted a demonstration of the 
effectiveness of its decentralized network, as required by the National 
Highway Systems Designation Act of 1995 (NHSDA). Approval of this 
submission will remove all remaining de minimus conditions imposed by 
EPA in its January 28, 1997 interim conditional approval of the 
Commonwealth of Pennsylvania's March 1996 enhanced I/M SIP revision. 
This action proposes approval of Pennsylvania's decentralized network 
effectiveness demonstration. Because EPA is proposing approval of that 
demonstration, as well as all remaining de minimus deficiencies related 
to Pennsylvania's enhanced I/M SIP, EPA hereby proposes to convert the 
interim approval of the Commonwealth's I/M SIP, granted under the 
NHSDA, to full approval. Because Pennsylvania must still provide 
specific information related to one condition of EPA's January 28, 1998 
approval, the Commonwealth's I/M SIP would remain conditionally 
approved under the Clean Air Act. In the Final Rules section of this 
Federal Register, EPA is issuing a direct final rule approving the 
Commonwealth's August 21, 1998 submission. The Agency views this 
rulemaking action as noncontroversial and anticipates no adverse public 
comment. A detailed rationale for the approval is set forth in the 
direct final rule and in the technical support document prepared by EPA 
for this action. If no adverse comments are received, no further 
activity is contemplated with relation to this rule. If EPA receives 
adverse comments, the direct final rule will be withdrawn and

[[Page 49518]]

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 16, 1998.

ADDRESSES: Written comments should be addressed to Marcia Spink, 
Associate Director, Air Programs, Mailcode 3AP20, U.S. Environmental 
Protection Agency, Region III, 1650 Arch Street, Philadelphia, 
Pennsylvania 19103. Copies of the documents relevant to this action are 
available for public inspection during normal business hours at the Air
