ACTION: Notice of proposed rulemaking. ----------------------------------------------------------------------- SUMMARY: EPA proposes to approve revisions to Colorado's prevention of significant deterioration (PSD) permitting requirements in Regulation No. 3, which were submitted as revisions to the State Implementation Plan (SIP) by the Governor on August 1, 1996. EPA also proposes to delete the TSP area designation table and to revise the PM-10 area designation table in 40 CFR part 81 for Colorado. In addition, EPA proposes to amend the language in 40 CFR 52.343(a)(3) to clarify Colorado's PSD permitting authority. In the final rules section of this Federal Register, the EPA is approving the State's SIP revision and promulgating these amendments as a direct final rule without prior proposal because the Agency views this action as noncontroversial and anticipates no adverse comments. A detailed rationale for the action is set forth in the direct final rule. If no adverse comments are received in response to this proposed rule, no further activity is contemplated in relation to this rule. If EPA receives adverse comments, then the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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 notice. Any parties interested in commenting on this notice should do so at this time. DATES: Comments on this proposed action must be received in writing by April 21, 1997. ADDRESSES: Written comments on this action should be addressed to Vicki Stamper, 8P2-A, at the EPA Regional Office listed below.
