Montclair Municipal Code Art. XII Special Restrictions

A. Food Service Establishments. Any person who operates, owns or maintains a food service establishment shall cause all floor drains, floor sinks, sinks, waste container wash racks, dishwashers, and garbage grinders to be directed through a minimum 750-gallon gravity separation interceptor and shall keep all domestic wastewater from rest rooms, showers, drinking fountains, and condensate (i.e., ice melt or air conditioning) separate from the food service wastewater until the food service wastewater has passed through all necessary pretreatment equipment, devices, or monitoring stations.

B. Vehicle Servicing Facilities. Any facility maintained for the servicing or repair of vehicles, construction equipment, industrial transportation, or power equipment shall install and maintain adequate sand and oil interceptors. All wastewater arising from the servicing and repair of vehicles shall pass through this interceptor before being discharged into the City sewer system. If the vehicle servicing facility does not include facilities for the washing of more than one vehicle at a time, the interceptor shall have an operation fluid capacity of at least 750 gallons. If the vehicle servicing facility has the capacity for washing or cleaning more than one vehicle at a time, the size of the interceptor shall be determined on a case-by-case basis.

C. Conditional Waivers. Conditional waivers for the grease and/or sand and oil interceptor requirement may be granted by the City Engineer for food service establishments or vehicle service facilities if it is determined that such waiver would not have an adverse effect on the City sewer system or the Inland Empire Utilities Agency's regional treatment plant. Conditional waivers may be revoked for the following reasons:

1. Changes in menu;

2. Falsification of information submitted;

3. Change in operation hours;

4. Changes in equipment used;

5. Changes in number of vehicles washed; or

6. Such waiver causes adverse effects on the City sewer system or the Inland Empire Utilities Agency's regional treatment plant.

D. Interceptor Requirements.

1. All interceptor chambers shall be immediately accessible at all times for the purpose of inspection and cleaning. At no time shall any material, debris, obstacle or obstruction be placed in such a manner as to prevent immediate access to the interceptor.

2. Any interceptor legally and properly installed before December 7, 1973, shall be acceptable as an alternative to the interceptor specified in this section, provided such interceptor is effective in removing floatable and settleable material and is so designed and installed that it can be inspected and properly maintained.

3. If the City Engineer finds that an interceptor is incapable of adequately retaining the floatable and settleable material in the wastewater flow, is structurally incomplete, or is undersized for the facility, he/she shall condemn such interceptor and declare that it does not meet the requirements of this chapter and shall require the user to install, at the user's expense, an acceptable interceptor.

E. Interceptor Designs. Wastewater from domestic usage shall be routed so that it shall not be allowed to pass through the interceptor. The interceptor shall be designed to retain any oil and grease which will float and any sand which will settle. It shall be watertight, structurally sound and durable, and easily accessible for cleaning. The City Engineer shall have the right to periodically inspect the interceptor for proper operation.

F. Interceptor Maintenance. The interceptor shall be properly maintained. It shall be cleaned as often as is necessary to ensure that settleable and floatable materials do not accumulate to impair the efficiency of the interceptor. When an interceptor is cleaned, the accumulated sediment and floating material shall be removed by trucking to a legally designated disposal site. All locations required to use and maintain a grease trap or interceptor shall keep maintenance and pumping records. These records shall include the date, the name of the waste hauler, and the disposal site of the waste. An interceptor is not considered to be properly maintained if accumulations of sediments and floating material total more than 25 percent of the operating fluid capacity. The owner of any vehicle servicing facility, the lessee and sublessee, if there is such, and any proprietor, operator or superintendent of such facility are individually and severally liable for any failure of proper maintenance of such interceptor.

A. Statutory Authorization. This chapter is enacted pursuant to authority contained in Section 13148 of the California Water Code and exercises authority conferred by law including, but not limited to, Chapter 5, Part 12, Division 104 of the Health and Safety Code and Order No. R8-2010-0008 of the California Regional Water Quality Control Board, Santa Ana Region, and Ordinance No. 921 of the Inland Empire Utilities Agency.

B. Purpose. The purpose of this chapter is to protect the quality of the waters of the state including, but not limited to, protecting beneficial uses of the Chino Basin and the entire Santa Ana watershed, and to allow for the effective recycling of water to meet the water supply of the residents of the community.

C. Findings.

1. The State Legislature has found and declared that elevated levels of salinity in community sewer systems can hinder needed water recycling projects, and discharges from those systems may impair groundwater resources and surface waters of the state.

2. The California Regional Water Quality Control Board, Santa Ana Region (Regional Board), has determined that the Santa Ana River Basin, including the Chino Basin, faces water quality challenges due to salinity pollution resulting from historical agricultural and other activities. (Resolution No. R8-2004-0001)

3. The Regional Board has adopted the 2004 Basin Plan Amendment, which sets water quality objectives that protect beneficial uses and provide maximum benefit to the users of the Santa Ana River Basin and to the State of California. (Resolution No. R8-2004-0001)

4. Producing high-quality recycled water is imperative to the regional initiative within Inland Empire Utility Agency's (IEUA) service area to maximize beneficial reuse of recycled water through landscape irrigation, industrial reuse, and groundwater recharge.

5. Reuse of recycled water is a critical component of the regional plans to reliably meet current and future water needs for the City of Montclair as well as the communities served by the IEUA.

6. In accordance with Section 13148(e) of the California Water Code, the Regional Board has found that the control of residential use of self-regenerating water softeners will contribute to the achievement of the water quality objectives approved in the 2004 Basin Plan Amendment. This finding is based on evidence demonstrating that salinity input from residential use of self-regenerating water softeners is a significant source of controllable total dissolved solids within IEUA's sewer system and that significant regional economic impacts will result if residential use of self-regenerating water softeners is not controlled. (Order No. R8-2010-0008)

D. Prohibition. It is unlawful to install or cause to be installed, replace, or enlarge any self-regenerating water softening appliance that is used for softening all or any part of the water supply to any premises when such appliance is regenerated by the onsite application of a salt-containing brine solution with the regenerated wastes being discharged to the City's community sewer system.

(Ord. No. 11-921, § 2, 5-2-11)

A. Hospital and medical waste which is defined as "infectious waste" by the Hospital Council of Southern California may be disposed of in the City sewer system subject to the following limitations and requirements:

1. The material shall be ground by an approved grinder system capable of meeting the fineness of grind requirements of 1/2 inch in any dimension. Entry to the grinding mechanism shall be restricted to a 6-inch by 9-inch opening.

2. Pathologic specimens may not be disposed of into the City sewer system. Pursuant to the requirements of the Hospital Council of Southern California, pathologic specimens shall be segregated from other solid wastes and shall be contained in plastic bags or other suitable disposable containers which shall not exceed a capacity of 5 gallons and shall be colored red for identification. Container and contents shall be weighed and the weight recorded prior to disposal by means other than through the City sewer system. These records shall be retained for a minimum of three years and be made available to the City Engineer upon request.

B. Disposable hypodermic needles, syringes, and associated articles following their use in hospitals, outpatient clinics, medical and dental offices, etc., may be ground and discharged to the City sewer system subject to the following limitations and requirements:

Such material shall be ground by an approved grinder not exceeding 5 horsepower and shall meet the fineness of grind requirements of 1/2 inch in any dimension. Entry to the grinding mechanism shall be restricted to a 6-inch by 9-inch opening.

C. Traps are to be installed and maintained in all waste sinks and toilets.
