Document 2026-08373 is a Proposed Rule published by the Environmental Protection Agency in the Federal Register on April 30, 2026. The Environmental Protection Agency (EPA) is proposing to approve revisions to the state implementation plan (SIP) for three state regulations submitted by the State of Delaware through the Delaware Department of Natural Resources and Environmental Control (DNREC) on February 3, 2025. The proposed 2025 revisions to the SIP amend certain startup and shutdown provisions in a manner that avoids the deficiencies that the EPA identified in a disapproval action dated October 23, 2023, in which the Agency disapproved portions of a prior SIP revision dated November 22, 2016. This action is being taken under section 110 of the Clean Air Act (CAA).
