(1) At no time shall any dry-cleaning solvent, wastes containing dry-cleaning solvent, or water containing dry-cleaning solvent be discharged onto land or into waters of the State, sanitary sewers, storm drains, floor drains, septic systems, boilers, or cooling- towers. All invoices generated as a result of disposal of all dry-cleaning solvent waste shall be made available for review upon request by the Department. If a dry-cleaning facility uses devices such as atomizers, evaporators, carbon filters, or other equipment for the treatment of wastewater containing solvent, all records, including invoices for the purchase, maintenance, and service of the devices, shall be made available upon request by the Department. Records shall be kept for a period of three years.

(2) Spill containment shall be installed and maintained under and around dry-cleaning machines, filters, dry-cleaning solvent pumps, stills, vapor adsorbers, solvent storage areas, and waste solvent storage areas. Spill containment shall have a volumetric capacity of 110 percent of the largest vessel, tank, or container within the spill containment area and shall be capable of preventing the release of the liquid dry-cleaning solvent beyond the spill containment area for a period of at least 72 hours. All floor drains within or beneath the spill containment area shall be removed or sealed with materials impervious to dry-cleaning solvents. Emergency adsorbent spill clean-up materials shall be on the premises. Facilities shall maintain an emergency response plan that is in compliance with federal, State and local requirements.
