[PA 042-4067b; FRL-5874-1]


Approval and Promulgation of Air Quality Implementation Plans; 
Pennsylvania; Approval of Definitions for the Pennsylvania VOC and 
NOX RACT and New Source Review Regulations

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA proposes to approve the State Implementation Plan (SIP) 
revision submitted by the Commonwealth of Pennsylvania. This revision 
establishes definitions for twenty-seven terms used in the new source 
review and reasonably available control technology (RACT) regulations. 
The intended effect of this action is to approve the definitions in 
Pennsylvania regulation, Chapter 121.1. In the Final Rules section of 
this Federal Register, EPA is approving the State's SIP revision as a 
direct final rule without prior proposal because the Agency views this 
as a noncontroversial SIP revision 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

[[Page 43134]]

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EPA receives adverse comments, the direct final rule will be withdrawn 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 September 11, 1997.

ADDRESSES: Written comments should be addressed to David L. Arnold, 
Chief, Ozone/CO and Mobile Sources, Mailcode 3AT21, U.S. Environmental 
Protection Agency, Region III, 841 Chestnut Building, Philadelphia, 
Pennsylvania 19107. Copies of the documents relevant to this action are 
available for public inspection during normal business hours at the

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