(Ord. 7362 § 6, 2017; Ord. 7032 §2, 2009; Ord. 6637 §2 (part), 2002; Ord. 6232 §2 (part), 1995)

A. At the direction of the Director, any user discharging wastewater into the POTW may be required to install sampling station(s) or measuring device(s) to measure the quality and quantity of wastewater discharged or to obtain samples. Measuring devices may include, but are not limited to: flow meters and recorders, pH meters and recorders, electrical conductivity meters and recorders, process water meters, and automatic wastewater samplers.

B. The sampling station and/or measuring device shall be provided by the user in compliance with this chapter and all applicable building, plumbing, and construction codes. The City may require access and that the measuring devices have a security closure that can be locked with a City lock and provide a City key. Construction shall be completed within a reasonable time as required in written notification from the Director.

C. The Director may temporarily install upon the user's property devices to conduct wastewater sampling, compliance monitoring or metering operations.

D. No user shall interfere with, delay, resist, or refuse entrance to authorized City personnel installing wastewater monitoring equipment on the user's property. Any permanent or temporary obstruction prohibiting direct access to the sampling station or measuring device shall be immediately removed by the user or property owner at the written or verbal request of the Director and shall not be replaced.

E. The sampling station or measuring devices shall be maintained for continuous sampling or metering. The measuring devices shall be calibrated a minimum of once per year by an outside contractor, or as often as necessary to ensure accurate measurements according to manufacturer's specifications. All maintenance and calibration work shall be performed at the user's expense.

F. All users that self-monitor shall have all samples collected and analyzed according to 40 CFR 403.12(b)(5).

G. All user sampling and analysis must comply with 40 CFR part 403.12(b)(5) and 40 CFR part 136. The laboratory must be certified by the State of California, Department of Health Services as being competent to perform the pollutant analyses requested, shall perform all laboratory analyses and must be acceptable to the Director. All samples must have the following information:

1. The date, exact place, method, and time of sampling and the names of the person or persons taking the samples;

2. The dates the analyses were performed;

3. Who performed the analyses;

4. The analytical techniques/methods used;

5. The results of such analyses;

6. A copy of the laboratory sample analysis sheet;

7. Chain of custody; and

8. The user's completed monitoring report form.

H. All users required to install and maintain measuring devices shall immediately report the failure of such devices. The immediate notification shall be by telephone call, telefax transmission, electronic report, email, personal visit, or a hand-delivered notification to the City's Environmental Compliance Office. Within five calendar days after discovery of the failure, the user shall submit a written report to the Director documenting the dates, times, and cause of the failure, and the corrective actions taken.

I. Any wastewater samples taken from a user's approved or designated sampling location shall be considered representative of the wastewater discharged to the POTW. For users that have interceptors, but no approved or designated sampling location, the last chamber of the interceptor shall be the designated sampling location. The user must collect wastewater samples using 24-hour flow-proportional composite sampling techniques, unless time-proportional composite sampling or grab sampling is deemed equally representative and authorized by the Director. Where time-proportional composite sampling or grab sampling is authorized by the City, the samples must be representative of the discharge. Using protocols (including appropriate preservation) specified in 40 CFR Part 136 and appropriate EPA guidance, multiple grab samples collected during a 24-hour period may be composited prior to the analysis as follows: for cyanide, total phenols, and sulfides the samples may be composited in the laboratory or in the field; for volatile organics and oil and grease, the samples must be composited in the laboratory. Composite samples for other parameters unaffected by the compositing procedures as documented in approved EPA methodologies may be authorized by the City, as appropriate. In addition, grab samples may be required to show compliance with applicable instantaneous limits and local limits.

J. All users required to self-monitor shall notify the Director of pollutant violations from any required wastewater sample within 24 hours of becoming aware of the violation. The notification may be by telephone call, telefax transmission, electronic report, or a personal visit to the City's Environmental Compliance Office. The violation report shall contain the date and time of the sample, the daily discharge flow for the sample, possible explanations for the violation, and the date scheduled for the required resample. Failure to report pollutant violations as stated is a violation of this chapter and may subject the user to enforcement actions.

K. All users required to take daily 24-hour readings of their wastewater effluent flow shall notify Director of exceedance of its permitted flow within 24 hours of discovering the exceedance by telephone call, telefax transmission, electronic report, personal visit, or a hand delivered notification, to the City's Environmental Compliance Office or file a monthly report indicating the days of the month when the permitted flow was exceeded and the reason for the exceedance. The monthly report shall be submitted to the City's Environmental Compliance Office by the fifth business day following the end of the preceding month. The flow exceedance notice shall have the total flow, date of the violation, the reason for the flow exceedance, and the name of the person reporting the flow exceedance. Failure to report such flow exceedance is unlawful and may subject the user to enforcement actions.

L. All users with a discovered pollutant violation shall resample their wastewater discharge for that pollutant. This mandatory resampling is independent of any other wastewater sampling requirement. User shall notify the Director within 24 hours of becoming aware of the violation. User shall submit the laboratory results and all required forms from the resamples of the violation to the Director no later than 30 calendar days after the user discovers or becomes aware of the violation and a written explanation detailing the cause(s) and correction action(s) of the violation to the Director no later than ten calendar days after the user discovers or becomes aware of the violation. Failure to submit the laboratory results and all required documents within the 45-day requirement shall result in significant noncompliance for the user and the issuance of a notice of violation to the user.

M. All users whose wastewater discharge is sampled by the City and themselves shall be responsible for all resampling requirements contained in subsection L of this section when a pollutant violation is detected. The City shall notify the user of the resampling requirements by a telephone call, telefax transmission, email, or personal visit within 72 hours of confirming a pollutant violation. The repeat sampling is required to be performed within 30 days of becoming aware of a violation.

N. All users which desire to conduct their own wastewater sampling, or receive samples split from City samples, shall submit a written plan describing the equipment used, equipment cleaning methodology, employee training, sample preservation methods, and chain of custody procedures. The user's wastewater sampling plan must be approved by the Director prior to the implementation of the plan. Any sample taken by a user without an approved plan or from an unapproved laboratory shall not be valid and may subject the user to enforcement actions.

O. All users are required to submit all monitoring results including non-permit required samples according to 40 CFR 403.12(g) sampled at the appropriate sample point within 15 calendar days of receiving the sample or monitoring results.

P. All permitted users that take more than one grab sample in a single calendar day to demonstrate compliance with oil and grease shall also comply with the following conditions:

1. A minimum of four grab samples separated by a minimum of two hours each shall be taken in a single calendar day;

2. Each individual oil and grease grab sample shall be analyzed separately and the analytical results from each sample shall be averaged;

3. No single oil and grease grab sample shall exceed the user's permitted limit by more than 40 percent; and

4. The average result from all individual oil and grease grab samples taken in a single calendar day shall not exceed the user's permitted limit.

(Ord. 7551 §5, 2021; Ord. 7362 §6, 2017; Ord. 7099 §2, 2010; Ord. 7032 §2, 2009; Ord. 6637 §2 (part), 2002; Ord. 6232 §2 (part), 1995)

All users shall keep records of waste hauling, reclamations, wastewater pretreatment, monitoring device recording charts and calibration reports, effluent flow, and sample analysis data on the site of the wastewater generation. All these records are subject to inspection and copy by the Director. All records must be kept on the site of the wastewater generation for a minimum period of three years. The record retention period may be extended beyond three years in the event criminal or civil action is taken or an extensive user history is required. Records required by company or corporate policy to be kept off-site shall be telefaxed or submitted electronically to the Environmental Compliance Office within 72 hours of the records request. Failure to submit the records as required is a violation of this chapter and may result in enforcement actions.

K. If the Director finds, either by engineering knowledge or by observation, that an interceptor is incapable of adequately retaining floatable and settleable material in the wastewater flow, is structurally inadequate, or is undersized for the facility, the Director may reject such interceptor and declare that the interceptor does not meet the requirements of this section. The user shall thereupon be required to, modify or repair the interceptor, or install an adequate interceptor, acceptable to the Director at the user's expense.

(Ord. 7551 §10, 2021; Ord. 7362 §6, 2017; Ord. 7032 §2, 2009; Ord. 6637 §2 (part), 2002; Ord. 6232 §2 (part), 1995)

The Director shall maintain a file, available to the public, of suitable interceptor designs. This file shall be for informational purposes only and is not an endorsement of any kind. Installation of an interceptor of a design shown in this file, or of any design meeting the size requirements set forth in this chapter, shall not subject the City to any liability for the adequacy of the interceptor under actual conditions of use. The user and property owner shall not be relieved of the responsibility for keeping floatable and settleable material out of the POTW.

(Ord. 7032 §2, 2009; Ord. 6637 §2 (part), 2002; Ord. 6232 §2 (part), 1995)

A. Any person who owns or operates an interceptor shall properly maintain it at all times to ensure the continued operation of the great interceptor, as designed, and to avoid causing a surcharge or overflow. The interceptor shall be cleaned as often as necessary to ensure that sediment and floating materials do not accumulate to impair the efficiency of the interceptor and odors do not cause a public nuisance. An interceptor is not considered to be properly maintained, if for any reason the interceptor is not in good working condition or if the operational fluid capacity has been reduced by more than 25 percent by the accumulation of floating material, sediment, oil or grease, or other liquids that have limited or no solubility in water.

B. The use of chemicals, enzymes, proteins or other materials to emulsify, suspend, or dissolve oil and grease is prohibited. If a user is found using any of these materials, the materials may be confiscated without restitution to the user and the user may be subject to enforcement actions.

C. No user shall use any microbiological product in a grease interceptor that was not specifically designed to use such microbiological agents to metabolize fats, oils, and greases. If a user is found using any of these materials, the materials may be confiscated without restitution to the user and the user may be subject to enforcement actions.

D. When an interceptor is cleaned, the entire contents of the interceptor from all chambers and sample box shall be removed. The removed sediment, solids, liquid and floating material shall not be reintroduced or decanted into the interceptor, sample box, sewer cleanout, other interceptor or other unlawful opening of a collection system or private sewer systems and shall be lawfully disposed of other than to the private sewer systems, POTW or storm drain, and shall not be reintroduced into the interceptor or discharged into another interceptor at another location not designed and permitted to accept such waste.

E. If the interceptor is not maintained adequately, then the interceptor shall be resized and the user shall install one that is effective in accomplishing the intended purpose, or the City may require a mandatory pumping schedule for the interceptor. Failure to pump the interceptor as required is a violation of this chapter and may subject the user to enforcement action.

F. The owner and lessee, sub-lessee, proprietor, operator and superintendent of any facility, required to install an interceptor or use an existing interceptor are individually and severally liable for any failure to properly maintain such interceptor.

A. No person who owns, operates, or maintains a restaurant (restaurant user) shall discharge wastewater from such restaurant to the POTW without first receiving a written determination from Director, and complying with such determination, of the POTW interceptor requirements. Restaurant users shall complete and submit a Wastewater Discharge Survey Form and conditional waiver to the Director for review of interceptor requirements. Within ten business days of receipt of the Wastewater Discharge Survey Form, Director shall notify such restaurant user of Director's determination whether an interceptor is required prior to discharge into the POTW. It is unlawful for any restaurant user notified by the Director as needing an interceptor to discharge restaurant wastewater into the POTW without use of a grease interceptor.

B. The Director shall calculate the size of the interceptor in accordance with the Uniform Plumbing Code, as adopted by the City, provided that any restaurant determined to require an interceptor of more than 100 gallons and less than 750 gallons shall install a minimum 750-gallon interceptor. The Director's determination shall consider the type of restaurant, the condition of the collection system serving the restaurant, and the possible adverse effects caused by the restaurant's wastewater discharge. An under the sink grease trap is not allowed in the City unless the site is considered a zero-lot line business located in the downtown area of the City, meets certain requirements and also gets approved by the County.

C. Any restaurant user required to install an interceptor shall direct all wastewater and waste from floor drains, floor sinks, sinks, waste container wash racks, dishwashers, mop sinks, utility sinks and garbage grinders through an approved interceptor complying with this chapter. The user shall keep all domestic wastewater from restrooms, showers, drinking fountains, condensate (i.e., ice melt, air conditioning condensate), soda machines and bar sinks separate from the restaurant wastewater until the restaurant wastewater has passed through all interceptors, pretreatment equipment, or sampling stations.

D. All restaurant users shall separate, to the maximum extent practicable, all fats, oils, and greases from the restaurant wastewater for off-site disposal. Each restaurant user shall store these separated wastes in accordance with all applicable laws, rules, policies and regulations, including the Riverside County Department of Environmental Health and this chapter. If grease is stored outside in drum or bin the container should be secured from tipping over using a chain or other material and have a secure lid or cover on top. If grease is located in the trash enclosure the restaurant user shall clean-up any spills on the ground. The trash bin must remain closed.

E. All floor sinks and floor drains shall be equipped with screens or devices that exclude all particles larger than three-eighths inch in any dimension.

F. Any restaurant user required to install an interceptor shall maintain the interceptor in accordance with this chapter.

A. No restaurant user shall discharge any wastewater to a storm drain, service dock areas, parking lot, or to the ground. All wastewater generated by restaurants, including trash enclosure wash/rinse water and drive through wash/rinse water, shall be contained, collected, and disposed of to sewer through a mop sink, drain, or gravity separation interceptor as approved or hauled off-site and disposed of at a legal disposal site.

B. If a restaurant has a blocked sewer lateral or a failed sewage pumping device which causes the discharge of wastewater to the storm drain, service dock areas, parking lot, drive through areas, or to the ground, the restaurant user shall immediately cease all activities causing that discharge and immediately contact a plumber to have the discharges collected and, if necessary, have laterals cleared, televised and repaired. Failure to comply with this requirement shall be considered a violation of this chapter and shall subject the restaurant user to enforcement actions. If the City determines that public safety requires immediate action and the restaurant owner is unable to or unwilling to arrange for a pumping company and plumber, or City collections crew, the city may in its discretion contact a pumping company and plumber to mitigate the violation and charge the restaurant user for all associated costs. Any restaurant that does not have a grease interceptor but causes a lateral or sewer blockage due to grease in the line shall have to install a minimum 750-gallon size grease interceptor.

(Ord. 7551 §13, 2021; Ord. 7362 §6, 2017; Ord. 7099 §4, 2010; Ord. 7032 §2, 2009; Ord. 6637 §2 (part), 2002; Ord. 6232 §2 (part), 1995)

Notwithstanding Section 14.12.275 subsection B, the Director may conditionally waive the interceptor requirements for any restaurant user determined in the Director's discretion.

1. Not to pose adverse effects on the POTW;

2. Lack of space for installation and maintenance, cannot get proper slope for plumbing from kitchen to interceptor, or

3. Restaurant can justify alternate pretreatment method to control grease. The Director may revoke such conditional waiver and require the installation of an appropriately sized grease interceptor for the following reasons:

A. Changes in menu;

B. Falsification of information submitted in the City's wastewater discharge survey form;

C. Changes in operating hours;

D. Changes in maximum seating capacity;

E. Changes in maximum meals served per peak hour;

F. Changes in equipment used;

G. Changes in the nature of the wastewater discharged as determined by random and scheduled wastewater sampling and analyses; or

H. Any overflows or impairment of the proper function of the collection system or appurtenances caused by the restaurant user's wastewater discharge.
