Environmental Protection Agency June 8, 2020 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is proposing approval of a State Implementation Plan (SIP) revision submitted by the State of Missouri on January 14, 2019. Missouri requests that the EPA revise a state regulation approved in the SIP related to sulfur emissions from industrial, commercial, or institutional boilers or process heaters in the St. Louis metropolitan area. The revisions to this rule include adding incorporations by reference to other state rules, including definitions specific to the rule, and wording changes that are administrative in nature and do not change the interpretation of the rule or the applicability of the rule. The EPA's proposed approval of this rule revision is in accordance with the requirements of the Clean Air Act (CAA).
