### Project Title: Amendment ofMDAQMD Rule 464- Oil-Water Separators
Dear Ms. Sutkus:
The Mojave Desert Air Quality Management District (MDAQMD) requests that the California Air Resources Board submit amended Rule 464

- Oil-Water Separators, to the United States Environmental Protection Agency (USEPA) for inclusion in the State Implementation Plan (SIP). Rule 464 was amended to satisfy 42 U.S.C. §§75lla (Federal Clean Air Act §182) which requires oz one nonattainment areas implement RACT for sources subject to CTGs and for major sources of ozone precursers. The MDAQMD has an oil-water s eparator rule which was approved as RACT into the SIP in 1995 (60 FR 49772). This rule is subject to the CTG titled Control of Refinery Vacuum Producing System 3, Wastewater Separators and Process Unit Turnarounds (EPA-450/2-77-025 October , 1977). While this CTG specifically states applicability to petroleum refinery sources , the c urrent rule does not specify the refinery industry , but applies instead to similar equipment. Although the refinery industry is nonexistent in the MDAQMD , Rule 464 has been incorporated in the SIP with applicability for the type of oil-water separators that exist in the District. The proposed amendments update rule applicability, definitions , floating cover seal tolerances , control device efficiency , storage of skimmed oil and tar, recordkeeping , and test**thod .**  The District requests CARB to submit the proposed amendment ofRule 464 to replace the SIP version in effect in the MDAQMD. The MDAQMD rule book version was amended August 24 , 1994 , which was subsequent to the annexation of the Blythe/Palo Verde Valley from the South Coast Air Quality Management District (SCAQMD). The SIP approval for this action does not specifically cite inclusion of the Blythe/Palo Ve r de Valley , but the submission and approval were subsequent to the annex ation. Also, while the SCAQMD SIP submission of Rule 464 was prior to the annexation , the approval was subsequent to the annexation and the approval does not mention the ex clusion of the Blythe /Palo Verde Valley. This submission is reque sted to replace Rule 464 in the SIP for both the San Bernardino County and Riverside portions of the MDAQMD.
