## Abstract

The Mississippi Department of Environmental Quality (MSDEQ or agency) has requested that EPA delegate authority for implementation and enforcement of existing New Source Performance Standards (NSPS) which have been previously adopted by the agency but have remained undelegated by EPA, and has requested that EPA approve the mechanism for delegation (adopt-by-reference) of future NSPS. The purpose of MSDEQ's request for approval of its delegation mechanism is to streamline existing administrative procedures by eliminating any unnecessary steps involved in the Federal delegation process. With this NSPS delegation mechanism in place, a new or revised NSPS promulgated by EPA will become effective in the State of Mississippi on the date the NSPS is adopted-by-reference pursuant to a rulemaking of the MSDEQ, if the agency adopts the NSPS without change. "Adopt-by-reference" means the EPA promulgated standard has been adopted directly into the State regulations by reference to the Federal law. No further agency requests for delegation will be necessary. Likewise, no further Federal Register notices will be published. In this action, EPA is delegating authority to MSDEQ for implementation and enforcement of existing NSPS which have been previously adopted by MSDEQ and which are identified in the Supplementary Information section below. In addition, EPA is approving MSDEQ's "adopt-by-reference" mechanism for delegation of future NSPS.
