2017-04770. Air Plan Approval; Nevada, Lake Tahoe; Second 10-Year Carbon Monoxide Limited Maintenance Plan

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

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 nonattainment 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.

DATES:

Any comments on this proposal must arrive by April 10, 2017.

SUPPLEMENTARY INFORMATION:

Throughout this document, “we,” “us” and “our” refer to the EPA. This proposal addresses the following local plan, “2012 Revision to the Nevada State Implementation Plan for Carbon Monoxide: Updated Limited Maintenance Plan, for the Nevada Side of the Lake Tahoe Basin, Including Douglas, Carson City and Washoe Counties.”

In the Rules and Regulations section of this Federal Register, we are approving this local plan in a direct final action without prior proposal because we believe this SIP revision is not controversial.
