EPA is taking a direct final action to approve a revision to the applicable minor New Source Review (NSR) State Implementation Plan (SIP) for New Mexico submitted by the state of New Mexico on April 25, 2005, which incorporates a new regulation related to minor NSR preconstruction permitting for particulate matter emissions from cotton ginning facilities. The submitted Cotton Gin regulation provides an alternative preconstruction process for cotton ginning facilities that will emit no more than 50 tons per year of particulate matter. The new regulation prescribes, at a minimum, best technical control equipment standards, opacity limitations, and fugitive dust management plan requirements to minimize particulate matter emissions and establishes a minimum setback distance from the gin to the property line. EPA has determined that this SIP revision complies with the Clean Air Act and EPA regulations and is consistent with EPA policies. This action is being taken under section 110 of the Act.
