Document 2026-10776 is a Final Rule published by the Environmental Protection Agency in the Federal Register on May 29, 2026, with an effective date of June 29, 2026. The Environmental Protection Agency (EPA) is approving revisions to the volatile organic compound (VOC) requirements for Keystone Automotives Industries dba Saturn Wheel (Keystone) of Huntington County, Indiana. Keystone owns and operates an aluminum alloy wheel refurbishing and distribution facility at which it performs cold cleaner degreasing operations and is subject to the VOC rules under article 8 of the Indiana Administrative Code (IAC). On February 26, 2025, the Indiana Department of Environmental Management (IDEM) submitted a Commissioner's Order containing the revised requirements and requested that the EPA approved it as an amendment to the Indiana State Implementation Plan (SIP). IDEM is seeking the EPA approval of an equivalent control device and site specific Reasonably Available Control Technology (RACT) for Keystone's degreasing operations, as provided in IAC article 8. The EPA proposed to approve this action on February 27, 2026, and received no adverse comments.
