Air Plan Approval; Missouri; Restriction of Emissions From Lithographic and Letterpress Printing Operations
The Environmental Protection Agency (EPA) is taking final action to approve a State Implementation Plan (SIP) revision submitted by the State of Missouri on November 10, 2020. This final action will amend the SIP to revise a Missouri regulation which restricts volatile organic compound emissions from lithographic and letterpress printing operations in the St. Louis Metropolitan Area. Specifically, the State has revised this rule in order to clarify rule applicability, update incorporation by reference information, update test method references, clarify definitions, and remove unnecessary words to improve clarity. Approval of these revisions will ensure consistency between State and federally-approved rules.
