76-20. Dry Cleaning Establishments with Category I, II, IIIA and IIIB Equipment.
1. DEFINITIONS. In this section:
a. "ACGIH" means the American Conference of Governmental Industrial Hygienists.
b. "Attendant" means a person other than the operator who works at a dry cleaning establishment.
c. "Dry Cleaning Equipment" means any device which uses an organic solvent such as but not limited to perchloroethylene (perc) or any halogenated hydrocarbons to clean fabric or clothing.
d. "Category I - Transfer Style" means a separate washer/extractor and separate dryer/reclaimer.
e. "Category II - Vented Dry to Dry" means a single machine which completes both cleaning and drying. At the end of the dry cycle, a vent opens to the outside atmosphere or a separate carbon absorber for aeration. Installations of this type use cold water to recover solvent vapors during the dry cycle.
f. "Category IIIA - Non-vented Dry to Dry" means a single machine with refrigeration recovery of solvent vapor during the dry cycle. This category of dry cleaning equipment does not vent to the room or outside atmosphere during the wash/extract/dry cycle.
g. "Category IIIB - Non-vented Dry to Dry" means a single machine which includes all the features of category IIIA dry cleaning equipment plus an integral hermetically sealed carbon recovery system.
h. "Dry Cleaning Establishment" means any building or structure where dry cleaning solvents are used to clean any type of natural or synthetic fabric.
i. "Dry Cleaning Solvent" means a solvent used in the dry cleaning process including but not limited to halogenated hydrocarbons and stoddard solvents.
j. "Dwelling" means any building or structure which is wholly or partly used or intended to be used for living or sleeping by human occupants that include any appurtenances attached thereto.
k. "Floor Plan" means a blueprint or detailed sketch of the dry cleaning establishment that includes but is not limited to the following information: location of dry cleaning equipment, spill containment area, chemical storage areas, location of exhaust ventilation units, switches for ventilation units and all entrances and exits to the dry cleaning establishment.
L. "Low Toxicity Solvent" means any solvent with a TLV (Threshold Limit Value) 8-hour TWA (time-weighted average) greater than 500 ppm (parts per million).
m. "Operator" means a person who operates the dry cleaning equipment.
n. "PEL" means permissible exposures limit established by the federal occupational safety and health administration (OSHA) which is the time weight average (TWA) concentration that must not be exceeded during any 8-hour work shift of a 40-hour work week.
o. "Person" means any individual, firm, corporation or other legal entity.
p. "TLV" means threshold limit value established by the ACGIH which is the maximum time weighted average concentration of a substance to which nearly all workers may be repeatedly exposed, day after day, without adverse health effects.
q. "VOC" means volatile organic compounds.
2. PERMIT REQUIRED. No person, firm or corporation shall install or operate any dry cleaning equipment in any building located in the city unless they hold a valid permit issued by the department in the name of the person and for the specific building within which the dry cleaning equipment is contained.
3. APPLICATION FOR PERMIT. Any person, firm or corporation intending to install or operate dry cleaning equipment shall file an application for such permit on forms obtained from and returned to the department. In addition, a detailed floor plan shall be submitted with the application. The person shall apply for or have obtained an occupancy permit, issued by the department of city development, prior to application to the department for the operation of a dry cleaning establishment. No person shall modify an existing dry cleaning establishment without written notification and approval of the department and the department of city development.
4. ISSUANCE OF PERMIT, FEES.

Whenever any person, firm or corporation to whom a permit has been issued sells, leases or otherwise relinquishes control of a dry cleaning establishment, they shall within 5 business days hereafter notify the department and as a part of such notification provide the department with the name and address of the person to whom such control has been relinquished.
c. Permits are not transferable and are personal to the person issued and cannot be transferred, sublet, leased, assigned, given away or sold under any circumstances.
5. REVOCATION, DENIAL OR SUSPENSION OF PERMIT. a. Whenever inspection of any establishment containing dry cleaning equipment indicates that there is a violation of this section or of any rule or regulation promulgated pursuant to this section, the department may give notice to the person to correct such violation and revoke, deny or suspend the permit unless the violation is eliminated.
b. A permit to operate may be revoked, denied or suspended for cause or failure to comply with the requirements of this section.
6. INSPECTION OF PREMISES. The department is authorized to enter any part of the premises in which dry cleaning equipment is located at any time for the purpose of inspecting the installation and operation of said equipment and the building in which the same is located.

Category IIIA & Category IIIB dry cleaning equipment not equipped with loading door ventilation (as designed by the manufacturer) are exempt from the loading door ventilation requirement.
e. A department approved method of containing liquid leaks within storage, equipment and maintenance areas shall be provided. This may include, but is not limited to, diking of the floor in these areas, or providing an enclosure around the machine base large enough to hold a liquid volume equal to the maximum quantity of solvent which might escape. A means shall be provided by the dry cleaning establishment for draining the containment area of solvent in the event of a spill or leak. In the event of a spill or leak, the solvent shall be removed from the enclosure or diked area immediately. Documentation of proper disposal or reuse of solvent must be submitted to the department within 5 business days. In the event of a spill, if the recovered solvent is transferred to a holding tank, the tank shall be vented to the outside atmosphere. No underground tanks are permitted for storage of dry cleaning solvents.
f. The machine design and operation shall be such that the cleaned items are completely dried and minimal (de minimis) solvent is retained upon completion of the full dry cleaning cycle.
g. An interlock system shall be provided on all dry cleaning equipment to prevent the loading door from being opened during the entire cleaning cycle. This system may be either electrical or mechanical and so connected that in the event of a power failure only the operator can open the loading door.
h. Only the solvent or solvents specified by the manufacturer shall be used in the dry cleaning equipment.
i. Make-up air shall be provided at a rate sufficient to allow for proper operation of all gas and oil-fired equipment on the premises and shall be in compliance with all state and local building code regulations. A minimum work area temperature of 65EF shall be maintained at all times.
