EPA is making an interim final determination to stay the imposition of offset sanctions and to defer the imposition of highway sanctions based on a proposed approval of a revision to the Sacramento Metropolitan Air Quality Management District (SMAQMD or District) portion of the California State Implementation Plan (SIP) published elsewhere in this Federal Register. The SIP revision concerns two permitting rules submitted by the SMAQMD: Rule 214, Federal New Source Review, and Rule 217, Public Notice Requirements for Permits.
