Eldon Heaston, Executive Director 

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 (USEP A) 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 ozone nonattainment areas implement RACT for sources subject to CTGs and for major 

sources of ozone precursers. The MDAQMD has an oil-water separator 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 System3, Wastewater Separators and Process Unit 

Turnarounds (EPA-450/2-77-025 October, 1977). While this CTG specifically states 

applicability to petroleum refinery sources, the current 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 of Rule 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 Verde Valley, but the submission and approval were 

subsequent to the annexation. 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 exclusion of the Blythe/Palo Verde Valley. This submission is requested to replace 

Rule 464 in the SIP for both the San Bernardino County and Riverside portions of the 

MDAQMD.
