Approval and Promulgation of State Plans for Designated Facilities and Pollutants: Colorado, Montana, North Dakota, South Dakota, Utah, and Wyoming; Negative Declarations

The Environmental Protection Agency (EPA) is withdrawing a direct final rule published on June 5, 2017, because one adverse comment was received during the public comment period. The withdrawn rule pertained to the EPA's receipt and approval of 20 negative declaration letters from EPA Region 8 states. These letters of negative declaration are statements by the state certifying the absence of designated facilities of a certain solid waste incinerator category or class within its jurisdiction, which obviates the statutory requirement for the state to develop a Clean Air Act (CAA) section 111(d)/129 State plan for the regulation of designated facilities of that particular category or class.
