The Environmental Protection Agency (EPA) is approving an application from the State of North Dakota under the Safe Drinking Water Act (SDWA) to revise the State's existing Underground Injection Control (UIC) Program for Class I, III, IV, and V injection wells located within the State, except those in Indian country. North Dakota has revised its UIC Class I, III, IV, and V program regulations to transfer primary enforcement authority from the North Dakota Department of Health to the North Dakota Department of Environmental Quality.
