Air Plan Approval; Indiana; Keystone VOC RACT Alternative Control

What it does

The Environmental Protection Agency (EPA) is proposing to approve revisions to the volatile organic compound (VOC) requirements for Keystone Automotive 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 approve 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.
