Paso Robles Municipal Code Art. VII Pretreatment

A. IUs shall provide wastewater treatment as necessary to comply with this chapter and shall achieve compliance with all applicable categorical pretreatment standards, local limits, and prohibitions set out in this chapter within the time limits specified by the EPA, the state, or the director, whichever is more stringent. Any facilities necessary for compliance shall be provided, operated, and maintained in good working order at the IU's expense.

B. In the construction of new facilities, all domestic wastewater from restrooms, showers, drinking fountains, and other similar sources shall be kept separate from all industrial wastewater until the industrial wastewater has passed through any required pretreatment system or device and the industrial wastewater monitoring facility or stations.

C. Detailed plans describing such facilities and operating procedures shall be submitted to the city for review and shall be acceptable to the city before such facilities are constructed. The city's review of such plans and operating procedures shall in no way relieve the IU from the responsibility for modifying such facilities as necessary to produce a discharge acceptable to the city under the provisions of this chapter. Any subsequent proposed changes to the pretreatment facilities or methods of operation shall be reported to, and must be approved by, the city prior to the IU's implementation of the changes.

D. Any IU, including, but not limited to, car washes, vehicle/equipment wash areas, service stations, repair facilities, and manufacturing facilities that generates wastewater with sand, silt, oil, grease or other constituents that can be settled or separated, shall be required to install an interceptor designed to prevent the discharge of these constituents to the POTW. Interceptors located outdoors shall be covered and bermed to prevent the inflow of stormwater. All interceptors shall be of a type and capacity approved by the director in accordance with the California Plumbing Code and shall be of a capacity sufficient to provide the appropriate quality of effluent per this chapter and shall be located where it would be easily accessible for cleaning and inspection. Interceptors shall be maintained at the owner's expense, in continuous efficient operating condition, and shall provide for the periodic removal of accumulated materials. No such collected materials shall be introduced into any drainage piping or public or private sewer.

E. Food service establishments shall comply with Article V of this chapter.
