There are two types of industrial waste permit; City and Joint County. Permit applications must be completely filled out and signed by the person responsible for the waste discharge. Since this is an operating permit application, the signature of the consultant is not acceptable.
- City Industrial Waste Permit Application Form: This permit is required for facilities discharging LACSD exempt industrial wastewater (Section 1.2) to the sanitary sewer, recycling wastewater on-site, or hauling non-hazardous industrial waste to an off-site disposal facility. A joint permit is required if your facility is discharging treated industrial wastewater to the sanitary sewer system and is NOT a listed exempt facility.
- LACSD Form (Joint Permit): Submit this form for all sewered industrial waste facilities which are not exempted by the LACSD. A joint permit is required if your facility is discharging treated industrial wastewater to the sanitary sewer system and is NOT a listed exempt facility (Section 1.2). LACSD exempt sites are subject to a City permit.

The plans shall include the following information:
- One (1) set of plans for LACSD Joint Permits
- All plans shall be minimum size of 11" x 17"
- Name and the address of the facility discharging the wastewater on the lower right-hand corner of each plans
- Site plan drawn to scale showing acreage, adjacent cross streets, north arrow, and location of pretreatment system(s)
- Site utility plan
- Site drainage plan
- Architectural floor plan identifying each area in the building by its use, i.e., food preparation, car wash, plating, laboratory, storage, office, restrooms, etc.
- Plumbing plan showing all drains including floor drains, floor sinks, trench drains, service sinks, and supply/waste lines and facilities handling industrial wastewater from the point of origin to the connection to the point of disposal, i.e. public sewer, private disposal system, and/or holding facility for offsite disposal. All equipment or facilities generating industrial wastewater must be identified on the plans
- Detail drawings of all pretreatment systems with dimensions and manufacturer's specifications
- All above ground storage tanks/drums with proper spill containment details. Provision for spill containment is required where chemicals and/or waste materials may potentially enter the sewer system, storm drain, or contaminate soil. Spill containment should be designed for the volume of the largest tank or ten percent of the drum total (whichever is greater), plus six inches of rainfall over the containment area (if outdoors)
- All outside wastewater producing and storage areas shall have a permanent cover. If a roof is not feasible, a rainwater diversion system may be proposed.
- A person owning or operating premises containing industrial waste treatment or disposal facilities operated under a valid permit issued under the provisions of LACC, Title 20, Division 2, must submit a closure application form (PDF, 103 KB) when the operations that generated wastewater have terminated, and the pretreatment facilities are to be permanently closed.
- Closure authorizations may require soil samples and a closure report with a review fee depending on the site history and type of operation.
A permit processing fee and a plan check fee will be determined based on the type of industry and the facility location. Please contact this office for further information.
- Submit a letter on site business letterhead, describing the overall operation, the operations which generate wastewater, and proposed wastewater pretreatment systems.
- Pursuant to the LACC, Title 20, Division 2, Section 20.32.440, the allocable peak discharge rate to a public local sewer from a heavy industrial zoned property is calculated at 0.021 cubic feet per second (cfs) per acre, equivalent to 9.4 gallons per minute (gpm) per acre. Administratively, parcels smaller than or equal to 0.8 acres are allowed a peak maximum discharge rate of 7.5 gpm. Additional sewer capacity above the allotted amount will require a sewer capacity clearance from the local jurisdiction.
