Proposed rule.


The Environmental Protection Agency (EPA) is proposing approval of a State Implementation Plan (SIP) revision submitted by the State of Nevada (“State”). On December 15, 2003, the EPA redesignated the Lake Tahoe, Nevada area (area), consisting of the Nevada portion of the Lake Tahoe basin in Nevada's Washoe, Carson City and Douglas counties, from Start Printed Page 13270nonattainment to attainment for the carbon monoxide (CO) national ambient air quality standards (NAAQS) and approved the State's plan addressing the area's maintenance of the CO NAAQS for ten years. On April 3, 2012, the State submitted to the EPA a second CO maintenance plan for the area that addressed maintenance of the CO NAAQS through 2024. On August 26, 2016, the State submitted a supplement to their 2012 submittal. The EPA is also proposing to approve an alternative CO monitoring strategy for the area, that the State included in their August 2016 submittal. We are making this proposal under the Clean Air Act.
