The Environmental Protection Agency (EPA) is taking final action to approve a State Implementation Plan (SIP) revision submitted by the State of Missouri on February 15, 2019. This final action will amend the SIP to revise a Missouri regulation which restricts the emissions of volatile organic compounds from wood furniture manufacturing operations in St. Louis City and Jefferson, St. Charles, Franklin, and St. Louis Counties. These revisions do not have an adverse effect on air quality.
