Approval and Promulgation of State Implementation Plans; California; Regional Haze Progress Report

The Environmental Protection Agency (EPA) is approving a revision to the California Regional Haze (RH) State Implementation Plan (SIP) submitted by the California Air Resources Board (CARB) documenting that the State's existing plan is making adequate progress to achieve visibility goals by 2018. The revision consists of the California Regional Haze Plan 2014 Progress Report that addresses the Regional Haze Rule (RHR) requirements under the Clean Air Act (CAA) to describe progress in achieving visibility goals in Federally designated Class I areas in California and nearby states. EPA is taking final action to approve California's determination that the existing RH SIP is adequate to meet these visibility goals and requires no substantive revision at this time.
