Lancaster Municipal Code Art. 4 Facilities Requirements

Upon original application or renewal, if the FSE has not previously provided:

A. FSEs shall submit two (2) copies of facility site plans, mechanical and plumbing plans, and details to show all sewer locations and connections. The submittal shall be in a form and content acceptable to the city for review of existing or proposed grease control device, grease interceptor, monitoring facilities, metering facilities, and operating procedures. The review of the plans and procedures shall in no way relieve the FSEs of the responsibility of modifying the facilities or procedures in the future, as necessary to produce an acceptable discharge, and to meet the requirements of this chapter or any requirements of other regulatory agencies.

B. Applicants shall submit site plans, floor plans, mechanical and plumbing plans, and details to show all sewers, FOG control device, grease interceptor or other pretreatment equipment and appurtenances by size, location, and elevation for evaluation.

C. FSEs shall submit a schematic drawing of the FOG control device, grease interceptor or other pretreatment equipment, piping and instrumentation diagram, and wastewater characterization report.

D. The city may require the drawings be prepared by a California registered civil, chemical, mechanical, or electrical engineer.

(Ord. No. 1066, § 2(Att. A), 9-24-2019)

A. All FSEs shall provide wastewater acceptable to the city under the requirements and standards established herein before discharging to any city sewer. Any FSE required to provide FOG pretreatment shall install, operate, and maintain an approved type and adequately sized grease interceptor.

B. Grease interceptor sizing and installation shall conform to the standards established in the California Plumbing Code, as may be amended from time to time. Grease interceptors shall be constructed in accordance with the design approved by the FOG control program manager and shall have a minimum of two (2) compartments with fittings designed for grease retention.

C. The grease interceptor shall be installed at a location where it shall be at all times easily accessible for inspection, cleaning, and removal of accumulated grease.

D. Access manholes shall be provided over each grease interceptor chamber and sanitary tee, of a size that conforms to state and local standards and requirements. Access manholes shall be installed and located in a manner that allows City inspectors easy access for sampling activities.

E. Dishwashers and food waste disposal units shall not be connected to or discharged into any grease recovery device.

F. All FSE's shall document each Grease Interceptor cleaning/pumping.

(Ord. No. 1066, § 2(Att. A), 9-24-2019)

A. FSEs may be required to install grease traps in the waste line leading from drains, sinks, and other fixtures or equipment where grease may be introduced into the sewer system in quantities that can cause blockage.

B. Sizing and installation of grease traps shall conform to the standards established in the California Plumbing Code, as may be amended from time to time, and must be an approved manufacturer by International Association of Plumbing and Mechanical Officials (IAPMO) or Plumbing & Drainage Institute.

C. Grease traps shall be maintained in efficient operating conditions by removing accumulated grease on a cleaning frequency that will ensure it will not reach twenty-five (25) percent accumulation. Such frequency will be set by the FOG Program Manager or his/her designee.

D. Grease traps shall be maintained free of all food residues and any FOG waste removed during the cleaning and scraping process.

E. Grease traps shall be inspected periodically by the permittee and at least annually by the inspector to check for leaking seams and pipes, and for effective operation of the baffles and flow regulating device. Grease traps and their baffles shall be maintained free of all caked-on FOG waste. Removable baffles shall be removed and cleaned during the maintenance process.

F. Dishwashers and food waste disposal units shall not be connected to or discharged into any grease trap.

G. All FSE's shall document each Grease Trap cleaning/pumping.

(Ord. No. 1066, § 2(Att. A), 9-24-2019)

A. The city may require an FSE to construct and maintain in proper operating condition at the FSE's sole expense, flow monitoring, constituent monitoring and/or sampling facilities The location of the monitoring or metering facilities shall be subject to approval by the FOG control program manager.

B. An FSE shall provide immediate, clear, safe and uninterrupted access to the FOG control program manager or inspectors to the FSE's monitoring and metering facilities.

C. FSEs may also be required by the FOG control program manager to submit waste analysis plans, contingency plans, and meet other necessary requirements to ensure proper operation and maintenance of the grease control device or grease interceptor and compliance with this chapter.

D. No FSE shall increase the use of water or in any other manner attempt to dilute a discharge as a partial or complete substitute for treatment to achieve compliance with this chapter and the FOG wastewater discharge permit.

(Ord. No. 1066, § 2(Att. A), 9-24-2019)

A. All FSEs shall implement best management practices in accordance with the requirements and guidelines established by the city under its FOG control program in an effort to minimize the discharge of FOG to the sewer system.

B. All FSEs shall be required, at a minimum, to comply with the following best management practices, when applicable:

1. Installation of drain screens. Drain screens shall be installed on all drainage pipes in food preparation areas.

2. Segregation and collection of waste cooking oil. All waste cooking oil shall be collected and stored properly in recycling receptacles such as barrels or drums. Such recycling receptacles shall be maintained properly to ensure that they do no leak. Licensed waste haulers or an approved recycling facility must be used to dispose of waste cooking oil and all manifests, and collections and disposals of same shall be documented on a city-provided log form and made available for City inspection upon request.

3. Disposal of food waste. All food waste shall be disposed of directly into the trash or garbage, and not into sinks. Double-bagging food wastes that have the potential to leak in trash bins is highly recommended.

4. Employee training. At the time of hiring and at least annually thereafter or as specified in the permit employees of the FSE shall be trained by ownership/management or permittee on the following subjects:

a. How to "dry wipe" pots, pans, dishware and work areas before washing to remove grease.

b. How to properly dispose of food waste and solids in enclosed plastic bags prior to disposal in trash bins or containers to prevent leaking and odors.

c. The location and use of absorption products to clean under fryer baskets and other locations where grease may be spilled.

d. How to properly dispose of grease or oils from cooking equipment into a grease receptacle such as a barrel or drum without spilling/splashing.

Training shall be documented and employee signatures retained indicating each employee's attendance and understanding of the practices reviewed. Training records shall be available for review at any reasonable time by the FOG control program manager or inspector.

5. Maintenance of kitchen exhaust filters. Filters shall be cleaned as frequently as necessary to be maintained in good operating condition. The wastewater generated from cleaning the exhaust filter shall be disposed of properly.

6. Kitchen signage. Best management and waste minimization practices shall be posted conspicuously in the clean-up and dishwashing areas at all times.

(Ord. No. 1066, § 2(Att. A), 9-24-2019)

C. FSEs with grease interceptors may be required to submit data and information necessary to establish the maintenance frequency of the grease interceptors.

D. Grease interceptors shall be fully pumped out and cleaned at a frequency such that the combined FOG and solids accumulation does not exceed twenty-five (25) percent of the total design hydraulic depth of the grease interceptor or every six (6) months, whichever occurs first.
