The Environmental Protection Agency (EPA) is taking direct final action to approve a State Implementation Plan (SIP) revision submitted by the State of North Dakota. On April 8, 2013, the Governor of North Dakota submitted to EPA an alternative monitoring plan for Milton R. Young Station (MRYS). The plan relates to continuous opacity monitoring for Unit 1 at MRYS. The intended effect of this action is to approve a state plan established to address minimum emission monitoring requirements. The EPA is taking this action under section 110 of the Clean Air Act (CAA).
