Certification and Permit Requirements for Perchlorethylene Dry Cleaners
CERTIFICATION OF ZERO DISCHARGE OF SEPARATOR WATER
Certification of zero discharge of perchloroethylene-contaminated separator water is met by completing the following requirements:
Seal or secure from spills and accidental discharges all floor drains in areas where perchloroethylene is stored or used. Cement plugs, standpipes or berms may be used for this purpose.
Choose one of the following approved separator wastewater disposal methods and comply with associated requirements:
REQUIREMENTS FOR PERMITTED DISCHARGE OF SEPARATOR WATER
If a dry cleaner chooses to continue to discharge separator water to the Districts' sewerage system, an industrial wastewater discharge permit must be obtained. In order to receive a permit, the discharger must complete a permit application in accordance with the Districts' Information and Instructions for Obtaining an Industrial Wastewater Discharge Permit, pay any local application fees, propose and install a pretreatment system capable of reducing perchloroethylene to below 5 mg/l (the saturation level for perchloroethylene is approximately 150 mg/l) and provide a standard sampling box for monitoring purposes. In addition, the discharger will be required to perform regular self-monitoring for perchloroethylene.
COST ESTIMATE FOR COMPLIANCE
In order to assist dry cleaners in deciding which method to use to comply with these regulations, estimates have been made of the costs of the different options. These estimates are general in nature and should only be used as a starting point for estimating actual costs.
COST ESTIMATES FOR COMPLIANCE
||WASTEWATER PERMIT FEES
Zero Discharge, Waste Hauling
||$4 per gallon (hauling fee)
|Zero Discharge, Evaporation
||$1,000 - $2,000 (evaporator purchase)
||$0.10 per gallon (energy)
|Industrial Wastewater Discharge Permit
|$1,000 - $2,000
(sample box purchase and installation
(carbon adsorption pretreatment)
It is anticipated that most dry cleaners will opt for zero discharge of separator water because of the capital cost of pretreatment and sample box installation and the recurring cost of self-monitoring for perchloroethylene.

To comply with these requirements your company must submit to the Districts either a completed Perchloroethylene Dry Cleaner Zero Discharge Certification for Separator Wastewater or a completed industrial wastewater discharge permit application. Should you choose to discharge separator water to the sewer, you should contact the Districts' Industrial Waste Section at 562-699-7411, extension 2900, and request a permit application package.
Failure to comply with these requirements will result in a violation of the Districts' Wastewater Ordinance resulting in enforcement action against your company. This could include petitioning the court for the imposition of civil liability in a sum not to exceed $25,000 per day of violation.
If you have questions regarding these requirements, please contact the Districts' Industrial Waste Section at (562) 699-7411, extension 2900, and ask for assistance.
