|Understanding the Industrial Waste Permit (Non-Domestic Waste Water) Program|
The City of Covina is required, by mandate, to protect the health and safety of the public while ensuring that the wastewater collection systems and treatment plants are not unduly impacted by discharges from industrial users.
An industrial user is a discharger of any water bearing waste other than domestic wastewater or of wastewater generated from household type operations performed at commercial establishments for or to support commercial purposes.
Businesses that are industrial users are generally required to obtain a Non-Domestic Wastewater Disposal Permit.
Existing and new businesses in the City of Covina are required to review the requirements set forth in the Industrial Waste Program Ordinance as specified by Ordinance No. 08-1953 and amended with Ordinance No. 10-1982 in Title 13 of the Covina Municipal Code and determine if they are required to comply with the ordinance. Examples of businesses that are required to apply for an industrial wastewater discharge permit are (but not limited to) metal finishing and plating shops, car washes, food service establishments, (restaurants, supermarkets, bakeries, etc.) laundries and printed circuit board manufacturers.
Please contact Environmental Services Division of the Public Works Department if you have questions or are not sure if you are required to apply for a permit.
Laws and Regulations
On May 2, 2006, the State Water Resource Control Board (SWRCB) adopted Order No. 2006-0003-DWQ (the Order) entitled, “Statewide General Waste Discharge Requirements (WDR’s) for Sanitary Sewer Systems.” The specific emphasis of the Order is the elimination of sanitary sewer overflows (SSO’s). To facilitate compliance with the Order, every agency responsible for the operation and maintenance of a sanitary sewer system was required to develop and implement a Sewer System Management Plan (SSMP), in compliance with the direction of the SWRCB. The City completed this state-mandated planning process with the City Council’s adoption of the City’s SSMP in July 2009.
The City’s industrial waste program, which is the front-line defense against fats, oils, and grease (FOG) related blockages and main line degradation, was virtually non-existent prior to the City Council adoption of Ordinance No. 08-1953 In May 2008. In April 2010, the City further amended Title 13 of the Covina Municipal Code pertaining to sanitary sewers, industrial wastes and the control of fats oils and grease in the sanitary sewer system by adopting Ordinance No. 10-1982, which strengthen and clarified the existing regulations.

Dry Cleaners/Laundry Service Centers
Uniforms worn by manufacturing personnel, hospital employees, and meat packers; shop towels used by service stations, printing companies, and bakers; and floor mats from offices, stores and schools are all items that are washed on a daily basis by industrial laundries.
The wastewater generated from industrial washers contains sand and grit, lint, free and emulsified oil and grease, heavy metals and volatile organic compounds (VOC’s). This program has been developed to ensure that no perchloroethylene (PERC) is discharged to the sewer, storm drain, or ground. All wastewater containing PERC or other solvent contaminated liquids should be properly disposed of by evaporation, or removed from the facility by a certified waste hauler.
Clothing treated with spotting agents containing TCE or PERC prior to wet cleaning or laundering can result in these chemicals being discharged with your wastewater. If even small amounts of TCE or PERC are discharged to a septic system, groundwater and nearby drinking water supplies may be contaminated. Therefore, it is very important that you avoid using spotting agents that contain PERC or TCE, especially if your wet cleaning or laundry machines discharge to a septic system. To minimize the potential to contaminate groundwater through wet cleaning or laundry discharge, you should use the following Best Management Practices:
Any facility that has at least one industrial sized washing machine will be required to obtain an Industrial Waste Permit.
Automotive Body/Service/Repair Centers
Although that car or van of yours looks like it just has a little dirt, oil or grease on it; imagine 500 to 2500 similar vehicles with the same amount of dirt on them being washed daily. Once the soap cuts through the grime, have you ever thought where does the grime and dirt go?
Well, it just doesn't go down the drain. All car washes are required to have what are called super traps beneath ground to catch all of the solids and sludges that accumulate. The typical super trap will contain anywhere from 1000 to 1500 gallons of this sludge that has to be removed on a regular basis.
Depending upon the amount of sludge that accumulates and the volume of vehicles that are cleaned; determines how often the super traps have to be cleaned out. When the time for cleaning is determined, Progressive Environmental Services sends in a vacuum truck to suck out or remove the sludge that is accumulated. This usually takes from one to several hours and allows the car wash to continue operating.
It is important to clean these traps on a regular basis because to fail to do so would result in this sludge entering the discharge pipes of the car wash and would put the car wash in violation of the local municipal sanitary discharge limitations for environmental compliance.
Food Service Establishments and FOG
What is FOG?
Why is FOG a problem?
A number of guides and informational materials are available here outlining ways to reduce FOG, proper maintenance of grease traps and interceptors, and information on vendors who specialize in grease hauling and interceptor maintenance that can help save you money. We encourage you to share this information with your management personnel and staff. Also included are posters detailing best management practices for the proper disposal of grease. Please display these posters in kitchen areas where easily viewable by your employees – preferably above sinks or drains.
What can be done to Stop FOG?
Understanding Grease Traps and Interceptors
A grease trap is designed to prevent grease, oil, solids, and other debris from entering the water stream, where it becomes a problem by clogging sewers and disrupting the water flow in the system.
A grease trap should be checked and frequently maintained to ensure it is working properly. Backups, odors, and drainage problems are signs that the grease trap is not functioning as it should.
Grease interceptors are larger than grease traps and are generally below-ground units located immediately outside of food preparation areas. These require less maintenance and are normally the preferred grease removal device.
Penalties may be incurred when overflows or other problems occur. The charge for pumping out a grease trap or interceptor is considerably more than the service fee charged by a renderer of segregated material. Furthermore, with dry cleanup and other source reduction techniques, many restaurants are reducing their water consumption and grease-related plumbing problems. Rendering also helps restaurants avoid discharge penalty charges.
