Performance Specification 18 (PS18) and Procedure 6 were originally promulgated in the Federal Register on July 7, 2015. Through a direct final rule and parallel proposal, the EPA made several minor technical amendments to PS18 and Procedure 6 to clarify several aspects of the original rulemaking. The PS18 amendments became effective August 17, 2016. On August 8, 2016, a partial withdrawal of the direct final rule was issued to withdraw the Procedure 6 amendments due to an adverse comment. The EPA responded to the comment and finalized the Procedure 6 amendments on September 21, 2017.
