Environmental Protection Agency July 10, 2017 – Federal Register Recent Federal Regulation Documents

On August 29, 2012, the Commonwealth of Kentucky, through the Kentucky Division for Air Quality (KDAQ), submitted changes to the Kentucky State Implementation Plan (SIP) on behalf of the Louisville Metro Air Pollution Control District (District or Jefferson County). The Environmental Protection Agency (EPA) is proposing to approve several changes that modify the District's air quality regulations as incorporated into the SIP. The changes to the regulatory portion of the SIP that EPA is proposing to approve pertain to definitional changes, administrative amendments, open burning, standards of performance, and volatile organic compounds (VOCs). EPA is proposing to approve these changes because the Commonwealth and Jefferson County have demonstrated that these changes are consistent with the Clean Air Act (CAA or Act).

EPA has received a specific exemption request from the Washington State Department of Agriculture to use the pesticide lambda- cyhalothrin (CAS No. 91465-08-6) to treat up to 7,000 acres of asparagus to control the European asparagus aphid. The applicant proposes a use which is supported by the Interregional Research Project number 4 (IR-4) program and has been requested in 5 or more previous years, and a petition for tolerance has not yet been submitted to the Agency. Therefore, in accordance with regulatory requirements, EPA is soliciting public comment before making the decision whether or not to grant the exemption.

Due to the receipt of an adverse comment, the Environmental Protection Agency (EPA) is withdrawing the May 30, 2017, direct final rule approving the redesignation of the Muncie nonattainment area to attainment for the 2008 national ambient air quality standards (NAAQS) for lead, the state's plan for maintaining the 2008 lead NAAQS through 2030 for the area, and the 2013 attainment year emissions inventory for the area.
