          - 40 CFR Part 52 
          - [PA 4091b; FRL-6569-1] 

# AGENCY:

Environmental Protection Agency (EPA). 

# ACTION:

Proposed rule. 

# SUMMARY:

                        EPA is proposing to approve revisions to the Commonwealth of Pennsylvania's State Implementation Plan (SIP). The revisions impose reasonably available control technology (RACT) on twenty-six major sources of volatile organic compounds (VOC) and nitrogen oxides (NOx) located in Pennsylvania. EPA is proposing these revisions to establish RACT requirements in accordance with the Clean Air Act. In the “Rules and Regulations” 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 comments. A more detailed description of the state submittal and EPA's evaluation are included in the Technical Support Documents (TSD) prepared in support of this rulemaking action. A copy of the TSD's are 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                               ( print page 20789)                            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.
