Approval and Promulgation of State Plans for Designated Facilities and Pollutants; North Dakota; Control of Emissions From Existing Municipal Solid Waste Landfills; Control of Emissions From Existing Commercial and Industrial Solid Waste Incineration Unit
The Environmental Protection Agency (EPA) is approving a Clean Air Act (CAA or the ``Act'') section 111(d) state plan submitted by the North Dakota Department of Environmental Quality (NDDEQ or the ``Department'') on July 28, 2020 for the control of air pollutants from existing municipal solid waste (MSW) landfills. The EPA is also approving a CAA section 111(d)/129 state plan submitted by the Department on the same date for the control of air pollutants from existing commercial and industrial solid waste incineration (CISWI) units and air curtain incinerator (ACI) units. The North Dakota state plans establish performance standards and operating requirements for existing MSW landfills, CISWI units and ACI units within the State of North Dakota and provide for the implementation and enforcement of those standards and requirements by the Department. Finally, the EPA is also approving withdrawal of the North Dakota CAA section 111(d)/129 state plan for the control of air pollutants from existing hospital/ medical/infectious waste incineration (HMIWI) units. The EPA is approving this plan withdrawal following North Dakota's May 8, 2019 submittal of a negative declaration of existing HMIWI units in the State of North Dakota, and will be promulgating the State's negative declaration in lieu of a CAA section 111(d)/129 state plan for HMIWI units. The EPA is taking these actions pursuant to requirements of the CAA.
