EPA approves revisions to the State Implementation Plan (SIP) submitted by the Governor of North Dakota with a letter dated September 28, 1998.

EPA will handle separately the revisions to the Title V operating permit program, a direct delegation request for emission standards for hazardous air pollutants for source categories, and the State's plan for hospital, medical, and infectious waste incinerators. Finally, EPA is providing notice that on May 7, 1999, North Dakota was delegated authority to implement and enforce the New Source Performance Standards (NSPS) in 40 CFR part 60, as of November 1, 1997, (excluding subpart Eb).
