The Mojave Desert Air Quality Management District (MDAQMD) is proposing to adopt Rule 1600 - Prevention of Significant Deterioration and provide amendments to Rule 1300 - General, Rule 1302 - Procedure and Rule 1320 - New Source Review for Toxic Air Contaminants.  The proposed changes, if implemented, will allow the Prevention of Significant Deterioration (PSD) program to be incorporated into the district rules, allowing the district to conduct nonattainment New Source Review (NSR) and issue PSD permits simultaneously.  In addition, USEPA now requires all local district rules involving NSR for nonattainment air contaminants to be revised to provide public notice for certain "minor" permit actions.

Proposed Rule 1600 will allow the MDAQMD to issue permits pursuant to the PSD program, and will work to harmonize terms between MDAQMD and those used in 40 CFR 52.21.  It is also important to note that the provisions in Rule 1600 do not apply to Major PSD Facilities or Major PSD Modifications in nonattainment areas with respect to the particular pollutant of concern.  The amendments to Rule 1302 will include PSD applicability analysis requirements for permit applications and a streamlined evaluation procedure.  Rule 1300 and Rule 1320 will be modified to provide cross references to Rule 1600 and add clarity to the rules.
