Clark County Transportation Conformity Plan, Clark County, Nevada (Las Vegas)

November 2008 - EPA published a direct final notice approving the Clark County Transportation Conformity Plan. Transportation conformity is required under section 176(c) of the Clean Air Act to ensure that federally supported highway, transit projects, and other activities are consistent with ("conform to") the purpose of the state implmentation plan. This means that transportation activites will not cause new air quality violations, worsen violations, or delay timely attainment of the relevant national ambient air quality standards.

No comments were received, and the approval was effective on January 6, 2009. The Federal Register notices and the technical support document, which contains EPA's evaluation of the Clark county transportation conformity plan, are included below.
