Air Plan Approval; Ohio; Lead
The Environmental Protection Agency (EPA) is approving, under the Clean Air Act (CAA), revisions to lead emissions rules in the Ohio Administrative Code (OAC). EPA is approving the removal of four lead emissions rules from the Ohio State Implementation Plan (SIP). Three of the lead emissions rules apply to Master Metals, Inc., a secondary lead smelter that has permanently shut down. The remaining lead emissions rule duplicates a provision in another OAC chapter that is approved into the Ohio SIP. EPA proposed to approve this action on March 12, 2021 and received no adverse comments.
