Approval and Promulgation of Air Quality Implementation Plans; Nevada; Rescission of Regional Haze Federal Implementation Plan for the Reid Gardner Generating Station

The Environmental Protection Agency (EPA) is proposing to rescind the Regional Haze Federal Implementation Plan (FIP) that we promulgated on August 23, 2012, to regulate air pollutant emissions from Reid Gardner Generating Station Units 1, 2, and 3 (RGGS), previously located in Clark County, Nevada. The EPA is proposing this action in response to the Nevada Division of Environmental Protection's (NDEP) request dated January 16, 2018. The request seeks rescission of the FIP because RGGS Units 1-3 have been permanently decommissioned and are being dismantled and demolished, as demonstrated by the supporting documentation provided by NDEP.
