Environmental Protection Agency April 26, 2018 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is proposing to approve certain portions of a State Implementation Plan (SIP) revision to address regional haze submitted by the Governor of North Dakota on March 3, 2010, along with SIP Supplement No. 1 submitted on July 27, 2010, SIP Amendment No. 1 submitted on July 28, 2011 and SIP Supplement No. 2 submitted on January 2, 2013 (collectively, ``the Regional Haze SIP''). Specifically, the EPA is proposing to approve the nitrogen oxides (NOX) Best Available Retrofit Technology (BART) determination for Coal Creek Station included in SIP Supplement No. 2. Coal Creek Station is owned and operated by Great River Energy (GRE) and is located near Underwood, North Dakota. This Regional Haze SIP was submitted to address the requirements of the Clean Air Act (CAA or ``the Act'') and our rules that require states to develop and implement air quality protection plans to reduce visibility impairment in mandatory Class I areas caused by emissions of air pollutants from numerous sources located over a wide geographic area (also referred to as the ``regional haze program''). States are required to assure reasonable progress toward the national goal of achieving natural visibility conditions in Class I areas. The EPA is taking this action pursuant to section 110 of the CAA.
