This rule applies to any dry cleaning facility which uses halogenated organic solvent.

(b) EXEMPTIONS (Rev. Effective 12/18/90)

  1. The provisions of this rule shall not apply to facilities using trichloro-trifluoroethane or 1,1,1-trichloroethane.

  2. The provisions of Section (d)(2) shall not apply to existing dry cleaning facilities using less than 320 gallons of halogenated organic solvent in every consecutive twelve-month period. It is the responsibility of any person claiming this exemption to maintain monthly records of usage of halogenated organic solvents. These records shall be retained on site for at least three years and shall be made available to the District immediately upon request.

(c) DEFINITIONS (Rev. Effective 12/18/90)

  1. "Dry Cleaning Facility" means any facility engaged in the cleaning of fabrics or leather in halogenated organic solvents. The facility includes, but is not limited to, washers, dryers, filter and purification systems, waste disposal systems, holding tanks, pumps, and attendant piping and valves.

  2. "Existing Dry Cleaning Facility" means a dry cleaning facility which was lawfully installed and operating before January 2, 1982.

  3. "Fugitive Liquid Leak" is defined as:

  4. (i) A leak of halogenated organic solvent at a rate in excess of three drops per minute; or

    (ii) A visible mist of halogenated organic solvent.

(d) REQUIREMENTS (Rev. Effective 12/18/90)

  1. A person shall not operate any dry cleaning facility unless:

  2. (i) There is no fugitive liquid leak from any portion of the dry cleaning facility.

    (ii) All washer lint traps, access doors and other parts of this equipment where halogenated organic solvent may be exposed to the atmosphere are kept closed at all times except when required for proper operation or maintenance.

    (iii) Still residues do not exceed a halogenated organic solvent content of 60 percent by weight.

    (iv) All diatomaceous earth filters are cooked or treated in a cooker which is vented to a condenser so that the residue contains no more than 25 percent halogenated organic solvent by weight.

    (v) All cartridge type filters are (1) drained in the filter housing for at least 24 hours before discarding the cartridges or (2) drained for at least 12 hours and dried in a closed dryer whose exhaust is vented through an air pollution control device, specified in Subsection (d)(2) of this rule.

    (vi) All waste from dry cleaning operations, including cartridge filters, which contains halogenated organic solvent must be stored and transported in sealed metal containers and shall be disposed of as set forth in California State Law regarding hazardous waste disposal as described in Title 22, Division 4, Chapter 30 of the California Administrative Code. Sealed containers other than metal may be used provided the containers are compatible with the waste and meet the requirements of the California Department of Health Services.

  3. A person shall not operate any dry cleaning facility unless the entire exhaust from drying tumblers, washers, and cabinets including uncondensed halogenated organic vapor from cooling coils is vented through an approved and properly functioning air pollution control device which meets one of the following conditions:

  4. (i) Ninety percent or more by weight of the halogenated organic compounds shall be removed by the device, or

    (ii) The concentration of halogenated organic compounds in the exhaust after the device and before dilution shall not exceed 100 ppmv as measured and averaged over a period of one-minute.

(e) RECORDKEEPING (Effective 12/18/90)

  1. Any person operating a dry cleaning facility using halogenated organic solvents shall maintain purchase records showing the date and amount of halogenated organic solvents purchased, and shall maintain daily records of the total dry weight of fabric processed.

  2. Any person operating a carbon adsorber which is subject to Subsection (d)(2) of this rule shall maintain records showing the dates on which the carbon was regenerated.

  3. All records shall be retained on site for at least three years and made available to the District immediately upon request.

(f) TEST METHODS (Effective 12/18/90)

Measurements of halogenated organic compounds pursuant to Subsections (d)(1)(iii) and (d)(1)(iv) of this rule shall be determined in accordance with ASTM Standard Recommended Practices for General Gas Chromatography Procedures E 260-73.

Measurements of halogenated organic compounds emissions pursuant to Subsection (d)(2) of this rule shall be conducted in accordance with EPA Test Method 25 (40 CFR 60, Appendix A) and EPA Guidelines for Measurement of Capture Efficiency as they exist on December 18, 1990.
