Air Plan Approval; Missouri; Restriction of Emissions From Lithographic and Letterpress Printing Operations
The Environmental Protection Agency (EPA) is proposing to approve revisions to the Missouri State Implementation Plan (SIP) received on November 10, 2020. The submission revises a Missouri regulation that 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 reference, clarify definitions, and remove the unnecessary use of restrictive words to improve clarity. Approval of these revisions will ensure consistency between state and federally-approved rules.
