(Adopted December 9, 1994)(Amended June 13, 1997)

RULE 1421. CONTROL OF PERCHLOROETHYLENE EMISSIONS FROM DRY CLEANING SYSTEMS.

(a) Purpose

The purpose of the rule is to protect public health by reducing perchloroethylene emissions from dry cleaning systems. This rule will implement the federal National Emission Standard for Hazardous Air Pollutants (NESHAP) for Source Categories: Perchloroethylene Dry Cleaning Facilities (40 Code of Federal Regulations [CFR] 63.320, et seq) and the state Airborne Toxic Control Measure (ATCM) for Emissions of Perchloroethylene from Dry Cleaning Operations (17 California Code of Regulations [CCR] 93109, et seq). This will be accomplished by requiring perchloroethylene dry cleaning facilities to: phase out transfer, vented, and self-service machines; require the use of a closed-loop, dry-to-dry machine; install primary and/or secondary controls as appropriate; and institute good operating, reporting, and recordkeeping practices.

(b) Applicability

The rule applies to all persons owning or operating a perchloroethylene dry cleaning facility.

(c) Definitions

For the purposes of this rule, the following definitions shall apply.

  1. ADSORPTIVE CARTRIDGE FILTER means a replaceable cartridge filter that contains diatomaceous earth or activated clay as the filter medium.
  2. CARTRIDGE FILTER means a replaceable cartridge filter that contains one of the following as the filter medium: paper, activated carbon, or paper and activated carbon. A cartridge filter contains no diatomaceous earth or activated clay. Cartridge filters include, but are not limited to: standard filters, split filters, "jumbo" filters, and all carbon polishing filters.
  3. CLOSED-LOOP MACHINE means dry cleaning equipment in which washing, extraction, and drying are all performed in the same single unit (also known as dry-to-dry) and which recirculates the perchloroethylene-laden vapor through a primary control system with no exhaust to the atmosphere during the drying cycle. A closed-loop machine may allow for venting to the ambient air through a fugitive control system after the drying cycle is completed and while the machine door is open.
  4. CO-LOCATED WITH A RESIDENCE means sharing a common wall, floor, or ceiling with a residence. For the purposes of this definition, "residence" means any dwelling or housing which is owned, rented, or occupied by the same person for a period of 180 days or more, excluding short-term housing such as a motel or hotel room rented and occupied by the same person for a period of less than 180 days.
  5. CONVERTED MACHINE means an existing vented machine that has been modified to be a closed-loop machine by eliminating the aeration step, and installing a primary control system, and providing for recirculation of the perchloroethylene-laden vapor with no exhaust to the atmosphere. A converted machine allows for venting to the ambient air through a fugitive control system after the drying cycle is complete and only while the machine door is open.
  6. COOL DOWN means the portion of the drying cycle that begins when the heating mechanism deactivates and the refrigerated condenser continues to reduce the temperature of the air recirculating through the drum to reduce the concentration of perchloroethylene in the drum.
  7. COMPLIANCE PERIOD means the time from the effective date of this rule in the District until a facility must be in compliance with the specific requirements of this rule.
  8. DESORPTION means the regeneration of an activated carbon bed, or any other type of vapor adsorber, by removal of the adsorbed solvent using hot air, steam, or other means.

    (C) Any liquid leak or vapor leak detected by the District, which has not been so noted on the checklist and marked on the leaking component of the dry cleaning system, shall constitute a violation of this section. For enforcement purposes, the District shall identify the presence of a vapor leak by determining the concentration of perchloroethylene with a portable analyzer:

    (i) according to ARB Test Method 21 (17 CCR, Section 94124, March 28, 1986); and

    (ii) measured 1 cm away from the dry cleaning system.

    (D) Any liquid leak or vapor leak shall be repaired within 24 hours of detection.

    (i) If repair parts are not available at the facility, the parts shall be ordered within two working days of detecting such a leak. Such repair parts shall be installed within five working days after receipt. A facility with a leak that has not been repaired by the end of the 15th working day after detection shall not operate the dry cleaning equipment, until the leak is repaired, unless a leak-repair extension is granted from the District.

    (ii) The District may grant a leak-repair extension to a facility, for a single period of 30 days or less, if the District makes these findings:

    (ii) sampling shall be conducted as follows:

    (I) for primary control systems and integral secondary control systems, sampling shall begin at the end of the drying cycle and be completed within 5 minutes;

    (II) for add-on secondary control systems, sampling shall be done when the concentration of perchloroethylene is 8,600 ppmv or greater and again when the concentration reaches 300 ppmv or less; and

    (III) sampling shall be completed prior to the opening of the machine door and activation of any fugitive control system.

    (iii) The perchloroethylene concentration in the drum shall be determined by one of the following methods: (I) A sampling port and valve shall be appropriately placed to draw a sample from the interior of the drum or the lint filter housing. The sampling port shall be connected to a gas chromatograph by one-quarter (1/4) inch, outside diameter, Teflon tubing. Any sampling pump shall have Teflon diaphragms. The gas chromatograph shall measure the concentrations of perchloroethylene in accordance with ARB Method 422 (17 CCR, Section 94132, December 31, 1991) or NIOSH Method 1003 (NIOSH Manual of Analytical Methods, U.S. Department of Health and Human Services, August 15, 1987).

    (II) A sampling port and valve shall be appropriately placed to draw a sample from the interior of the drum or the lint filter housing. The sampling port shall be connected by one-quarter (1/4) inch outside diameter Teflon tubing to a Tedlar bag. Any sampling pump shall have Teflon diaphragms. The concentration of perchloroethylene in the air sampled shall be measured in accordance with ARB Method 422 (17 CCR, Section 94132, December 31, 1991) or NIOSH Method 1003 (NIOSH Manual of Analytical Methods, U.S. Department of Health and Human Services, August 15, 1987) within 24 hours of sampling. If an independent laboratory is contracted to perform the analysis of the samples, the chain of custody procedures contained in ARB Method 422 or NIOSH Method 1003 shall be followed.

    (B) For a control device on the exhaust of a drying cabinet, sampling and analysis shall be conducted using ARB Method 422 (17 CCR, Section 94132, December 31, 1991) or NIOSH Method 1003 (NIOSH Manual of Analytical Methods, U.S. Department of Health and Human Services, August 15, 1987).

    (C) An alternative test method deemed acceptable by the Executive Officer of the District and the Executive Officer of the Air Resources Board.

  3. All test plans and test results shall be made available to the District and the Executive Officer of the California Air Resources Board upon request.

(k) Compliance Schedules

A facility shall comply with all provisions of this rule as follows:

  1. By the applicable dates of compliance specified in column 2 through column 8 of Table 1.
  2. For compliance with paragraph (e)(3) "Environmental Training Requirements," an alternative date of compliance shall apply if the District determines that the initial course of an environmental training program for perchloroethylene dry cleaning operations is not reasonably available.

    (A) For existing facilities in the District, if the initial course is not reasonably available within 12 months of the effective date of this rule in the District, the alternative date of compliance for paragraph (e)(3) only shall be 6 months from the date the District determines that the initial course is reasonably available.

    (B) For each new facility within the boundaries of the District, if the initial course is not reasonably available within the period from 3 months prior to 2 months following commencement of operation, the alternative date of compliance for paragraph (e)(3) only shall be 1 month from the date the District determines that the initial course is reasonably available.

(l) Major Sources

All major sources must comply with the requirements of 40 CFR Section 63.320, et. seq.
