Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; Approval of VOC and NOX RACT Determinations for Individual Source

Краткое содержание

EPA is proposing to approve revisions to the Commonwealth of Pennsylvania's State Implementation Plan (SIP). The revisions establish and require reasonably available control technology (RACT) for 56 major sources of volatile organic compounds (VOC) and nitrogen oxides ( NO X ) located in Pennsylvania. In the Final Rules section of this Federal Register, EPA is approving the revisions as a direct final rule without prior proposal because the Agency views these as noncontroversial submittals and anticipates no adverse comments. A more detailed description of the state submittals and EPA's evaluations are included in Technical Support Documents (TSDs) prepared in support of this rulemaking action. Copies of the TSDs are 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.

EPA will not institute a second comment period. Any parties interested in commenting on
