          - 40 CFR Part 52 
          - [PA155-4114b; FRL-6998-7] 

# AGENCY:

Environmental Protection Agency (EPA). 

# ACTION:

Proposed rule. 

# SUMMARY:

                        EPA is proposing to approve State Implementation Plan (SIP) revisions submitted by the Commonwealth of Pennsylvania. This action proposes to approve new volatile organic compound (VOC) regulations for the aerospace industry, and to add new definitions for terms used in regulations containing standards for VOC sources. This action also proposes to modify the approval process for the use of alternative compliance methods for certain VOC control requirements. In the Final Rules section of this                         **Federal Register**                        , EPA is approving the State's SIP submittal as a direct final rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comment. A more detailed description of the state submittal and EPA's evaluation 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 no adverse comments are received in response to this action, no further activity is contemplated. If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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. Any parties interested in commenting on this action should do so at this time. Please note that if EPA receives adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, EPA may adopt as final those provisions of the rule that are not the subject of an adverse comment.
