Approval and Promulgation of Implementation Plans Kentucky: Approval of Revisions to Kentucky State Implementation Plan

요약

On September 13, 1999, EPA published a direct final rule approving and an accompanying notice of proposed rulemaking proposing to approve the 15 percent Rate-of-Progress Plan (15 percent plan) for the Louisville moderate 1-hour ozone nonattainment area which was submitted on November 12, 1993, and amended on April 5, 1994, and June 30, 1997. As stated in the Federal Register document, if adverse or critical comments were received by October 13, 1999, the effective date would be delayed and timely notice would be published in the Federal Register. Due to receipt of adverse comments within the comment period, EPA withdrew the direct final rule on November 3, 1999, in order to address all public comments received. This action addresses the adverse comments related to the approvability of the emission reduction measures and grants final approval to the rule revisions and the 1990 Base Line Emissions Inventory. No comments were received relating to the 1990 Base Line Emissions inventory.
