The National Mining Association submits the attached comments on the U.S. Environmental Protection Agency's proposed rule, "Proposed Air Plan Partial Approval and Partial Disapproval; North Dakota; Regional Haze State Implementation Plan for the Second Implementation Period." 89 Fed. Reg. 55,693 (July 10, 2024); Docket No. EPA-R08-OAR-2023-0495.

Abstract

The Environmental Protection Agency (EPA) is proposing to partially approve and partially disapprove the regional haze state implementation plan (SIP) revision submitted by the State of North Dakota on August 11, 2022 (North Dakota’s 2022 SIP submission), as satisfying applicable requirements under the Clean Air Act (CAA) and the EPA’s Regional Haze Rule (RHR) for the program’s second implementation period. North Dakota’s 2022 SIP submission addresses the requirement that states revise their long-term strategies every implementation period to make reasonable progress towards the national goal of preventing any future, and remedying any existing, anthropogenic impairment of visibility, including regional haze, in mandatory Class I Federal areas. North Dakota’s 2022 SIP submission also addresses other applicable requirements for the second implementation period of the regional haze program. The EPA is taking this action pursuant to the CAA.
