(Ord. No. 18-07, 6-13-2018)

Legal measures available to the City to control sources of FOG include the following:

(1) Authority to prohibit discharges:

a. Municipal Code: This chapter includes prohibiting the disposal of grease.

b. No person shall dispose of any grease, or cause any grease to be disposed, by discharge into any drainage piping, by discharge into and storm drainage system, or by discharge to any land, street, public way, river, stream, or any other waterway.

(2) Requirement of grease removal device and cleaning log:

a. Grease traps capture grease from the wastewater flow. Grease traps slow down the flow of hot greasy water, allowing it to cool. As the water cools, the grease separates and floats to the top of the trap while the water flows down the pipe onto the sewer. The grease is trapped by baffles that cover the inlet and outlet of the tank. If the tank is not pumped frequently enough or the drain lines are not maintained properly, backups and blockages occur. The design of a grease trap is simple and there are many styles and sizes to choose from.

b. Grease traps come in varied designs and sizes. Plastic grease traps are now available at most restaurant supply stores.

c. Maintaining a grease trap is required for proper operation and will be required by this chapter. Some problems associated with improper maintenance include sewage backing up into your business, rancid odors expensive cleanup and repair, potential contact with disease causing organisms and higher operating costs.

d. Sewer Ordinance: This City's Sewer Ordinance requires a grease removal device for every commercial or industrial generator of grease. Additionally, the City's Sewer Ordinance requires that the business clean out the grease removal device. The log should be available for inspection for a 3-year period. The Owner is responsible as delineated below:

1. The Owner of every newly constructed, remodeled, or converted commercial or industrial facility with one or more grease generating activities including food service facilities with new or replacement kitchens, for which a building permit is issued, shall install or cause to be installed a grease interceptor for each grease generating activity, of a size equal to or greater than the minimum size meeting the definition of "grease removal device" as set forth in the Los Angeles County Pluming Code.

2. The owner of every commercial or industrial generator of grease, including food service facilities, serviced by a sewer collection line found to have a grease blockage, a history of grease blockage, or accelerated line maintenance resulting from grease disposal shall or cause to be installed a grease removal device.

3. The owner of every commercial or industrial generator of grease, including food service facilities, for which installation of grease removal devices is not required, shall install or cause to be installed a grease removal device for each grease generating activity.

4. All grease removal device(s) shall be installed on the premises where grease is used or generated and shall be sized in conformance with the Los Angeles Country Plumbing Code. The contents of all grease removal devices shall be removed periodically as necessary to prevent violations of this chapter. At a minimum, the contents shall be removed every six months. All grease removal devices shall be kept in good repair, and shall be maintained in continuous operation. A log of all grease removal activities shall be maintained at the facility showing the date of removed content. The log shall be retained for a period of three years, and shall be available for inspection by city inspectors upon request.

(3) Enforcement measures, as appropriate. This City's sewer ordinance includes enforcement measures for violations of any sewer protection measure, including grease discharge. These measures range from issuance of a notice of non-compliance to criminal penalties. Penalties are described below:

(a) Unless the City Inspector or the City's authorized representative finds that the severity of the violation warrants immediate action under this chapter, or permit revocation or suspension, he or she shall issue a notice of noncompliance which:

1. Enumerates the violations found; and

2. Orders compliance by a date certain.

(b) If the violations are not abated in the time period identified further action may be taken by the City Inspector or City's authorized representative including, but not limited to, suspension, revocation or modification of the discharger's permit.

(Ord. No. 18-07, 6-13-2018; Ord. No. 21-01, § 7, 7-28-2021)

"North American Industry Classification System (NAICS)" means a classification of business establishments developed and updated periodically by the Executive Office of the President, Office of Management and Budget.

(Ord. No. 18-07, 6-13-2018)

The City is responsible to provide a brochure that discusses grease and the role of fats, oils and grease in causing blockages. This brochure will be displayed at City Hall and posted on the City's website. Additionally, City staff or contract sewer maintenance crews will provide this brochure to residents who are affected by a blockage or backup.

(Ord. No. 18-07, 6-13-2018)

"Sanitary sewer overflows (SSO)" means any overflow, spill, release, discharge or diversion of untreated or partially treated wastewater from a sanitary sewer system. SSOs include:

(1) Overflows or releases of untreated or partially treated wastewater that reach waters of the United States;

(2) Overflows or releases of untreated or partially treated wastewater that do not reach waters of the United States; and

(3) Wastewater backups into buildings and onto private properties that are caused by blockages or flow conditions within the publicly owned portions of a sanitary sewer system.

(Ord. No. 18-07, 6-13-2018)

"Significant industrial user (SIU)" means that except where the control authority of a POTW has found an industrial user to be exempt pursuant to 40 CFR 403.3(v)(2) and (v)(3):

(1) All industrial users subject to categorical pretreatment standards under 40 CFR 403.6 and 40 CFR chapter I, subchapter N; and

(2) Any other industrial user that discharges an average of 25,000 gallons or more of process wastewater to a POTW (excluding sanitary, non- contact cooling and boiler blowdown wastewater); contributes a process wastestream which makes up five (5%) percent or more of the average dry weather hydraulic or organic capacity of the POTW treatment plant; or is designated as such by the POTW control authority on the basis that the industrial user has a reasonable potential for adversely affecting the POTW operation or for violating any pretreatment standard or requirement.

(Ord. No. 18-07, 6-13-2018)

"Slug discharge" means any discharge of a non-routine, episodic nature, including but not limited to an accidental spill or a non-customary batch discharge, which has a reasonable potential to cause interference or pass through, or in any other way violate the POTW's regulations, local limits or permit conditions. Discharge of any prohibited material in any concentration shall be considered a slug discharge.

(Ord. No. 18-07, 6-13-2018)

(a) In the event of an uncontrolled or slug discharge, the discharger or permittee shall immediately notify the City Engineer by telephone. The notification shall include location of the discharge, type of material, duration, concentration and volume, and corrective actions taken.

(b) Within one hundred five (105) days after the uncontrolled or slug discharge, the discharger or permittee shall submit to the City Engineer a detailed written report describing the cause of the discharge, corrective action taken and measures to be taken to prevent further occurrences. Such notification shall not relieve the discharger or permittee of liability or fines incurred as a result of the uncontrolled or slug discharge.

(Ord. No. 18-07, 6-13-2018)

(a) Purpose. The purpose of this section is to implement additional specific requirements for the use of the sanitary sewer system to ensure compliance with statewide general waste discharge requirements for sanitary sewer systems, State Board Order No. 2006-0003-DWQ (State Board Order) and as may be hereinafter amended or superseded.

(b) Duty of the discharger. All dischargers to the sanitary sewer system shall implement BMPs to ensure that their discharge, either singularly or in combination with other discharges, does not create a condition in the system that might cause damage to the system or a SSO. Commercial and industrial discharges shall be made only in full compliance of this chapter.

(c) Duty of Maywood as a tributary jurisdiction. Maywood is a jurisdiction owning a sanitary sewer system greater than one (1) mile in length that are tributary to the Los Angeles County trunk sewers and has enrolled per the State Board Order and has developed a sewer system management plan (SSMP) including adopting legal authority for the control of SSO. The SSMP is Chapter 11 of this Title 6.

(d) House lateral maintenance. Dischargers to the sanitary sewer system shall use house lateral maintenance procedures that maximize the recovery of delirious materials and minimize the passage of FOG, debris, cut roots and similar materials to the main- line sewers. Section 6-13.26.10 notwithstanding, no person shall interfere with the City's access to house laterals extending from the main-line sewer and the right-of-way boundary or property line.

(e) Identification of sewer cleaning. The primary means of FOG control utilized by the City will be the identification of trouble spots or sewer lines that are likely prone to grease accumulation and targeted cleaning of these areas on 30- or 60-day schedules and chemical root control measures to inhibit the growth of roots where grease may accumulate.

(1) Identification of grease problem areas. The City will identify potential grease problem areas by tracking locations and causes of sanitary sewer overflows. When a sewer overflow occurs, contract maintenance crews will note the reason that the overflow was caused. Additionally, the contract maintenance crews will note the debris type and severity during routine and focused cleaning. Areas with several restaurants or grease-producing facilities will be considered likely grease problem areas. Such facilities include food service establishments, high-density multi-family dwellings, single-family dwellings and food manufacturing facilities. The following is a list of projects that will be developed utilizing a sewer system GIS when implemented to inventory and characterize potential sources of FOG:

a. The City is developing and will compile a GIS application for the identification of sewer system blockages due to FOG and their potential sources including the following:

1. Identify and color code sewer code sewer collection lines subject to blockage,

2. Identify and plot all SSOs resulting from FOG blockages. If the source of the grease in a lateral can be identified, the City will contact the property owner to notify them of the problem and work with them to clean the lateral.

b. The City is developing a GIS based "hot spots" application for regular cleaning with query and reporting capabilities on the frequency of the said cleaning by location/date.

c. The City is developing a GIS based "source identification" application to identify and plot potential sources of FOG in "hot spot" areas.

d. The City's GIS application will include query and reporting capabilities to view the current land use, past inspection reports and the condition of grease removal equipment installed at these potential sources:

1. Food service establishments (including restaurants, hospitals, nursing homes, grocery stores and commissaries);

2. High density multi-family dwellings;

3. Residential I- single family dwellings; and

4. Food manufacturing (industrial).

(2) Identification of sewer cleaning. The primary means of FOG control utilized by the City will be the identification of troubled spots or sewer lines that are likely prone to grease accumulation and targeted cleaning of these areas on 30- or 60-day schedules and chemical root control measures to inhibit the growth of roots where grease may accumulate.

a. Identification of grease problem areas. The City will identify potential grease problem areas by tracking locations and cause of sanitary sewer overflows. When a sewer overflow occurs, City staff or contract maintenance crews will note the reason the overflow was caused. Additionally, debris type and severity will be noted by the City staff or contract maintenance crews during routine and focused cleaning. Areas with several restaurants and grease-producing facilities will also be considered likely grease problem areas. Such facilities include food service establishments, high density multi-family dwellings, single family dwellings and food manufacturing facilities.

b. Focused cleaning. Sewer lines that have been identified as being prone to FOG problems will be included in the 30- or 60-day focused cleaning schedule. Cleaning frequency should depend on the history of stoppages or overflows on a line, as well as areas expected to be prone to grease buildup. Lines that occur in areas with the highest concentration of restaurants will be included in the 30- or 60-day focused cleaning schedule.

The City will maintain tables of each manhole reach scheduled for focused cleaning. These tables will also be used as cleaning logs, on which maintenance workers note the date and time of flushing, as well as the debris type and severity.

If there are Sewers that are smaller than twelve (12") inches in diameter, which are not included in the focused cleaning program, they will be cleaned on a four-year cycle (twenty-five (25%) percent per year). This four-year cycle is consistent with industry standards.

c. Root foaming program. This chapter implements a cyclic root foaming program to cover a percentage of the City's sanitary sewer system annually. Roots penetrate the sewer lines and can damage the integrity or pipe and cause subsequent blockage of wastewater flows. Since grease tends to accumulate on roots, this program.

d. Blockage investigation. The City or its contract maintenance crews will inspect each sewer line following a blockage by CCTV. If the source of the grease in a lateral can be identified, the City will contact the property owner to notify them of the problem and work with them to clean the lateral.

(f) Illicit discharges prohibited. No person shall cause any discharge to the sanitary sewer system unless such discharge:

(1) Consists entirely of domestic sewage; or

(2) Consists of industrial waste that is authorized pursuant to the provisions of this chapter.

(g) Limitations: City Engineer may establish. The City Engineer may establish numerical limitations on the amount of fats, oils, and grease, and other debris that may cause blockages or contribute to SSOs on discharges to all or portions of the sanitary sewer system where the City Engineer finds that such limitation is necessary to protect the system from damage or potential SSOs. Industrial waste disposal permits issued pursuant to this chapter shall include such limitations where imposed.

(h) Existing FOG disposal systems. Existing grease interceptors, grease traps or other FOG disposal systems, previously approved by the director, may remain in service provided such systems are properly maintained to effectively reduce FOG discharges, are operating within original design parameters, have not been altered in a manner not approved by the City Engineer, and where required are operated under a valid industrial waste disposal permit pursuant to Chapter 20.36. Such authorization does not preclude the City Engineer from establishing discharge limitations which may require the modification, enlargement, addition, or replacement of FOG disposal system to protect the sanitary sewer system from blockages or overflows.

(i) Investigation of SSO incidents. The City Engineer shall investigate and determine the probable cause of an actual or potential SSO incident. In the course of any such investigation, the City Engineer may enter the premise of any discharger to the sanitary sewer system to determine the presence of potential sources of FOG, inspection of FOG disposal systems, review wastewater disposal procedures, ascertain if BMPs are in place and adequate, review records, photograph disposal systems, and take samples and other measurements in order to determine the cause or sources of an SSO. Subsection 6-13.26.10 notwithstanding, where the City Engineer determines that additional, improved, upgraded, repaired or more frequently maintained FOG removal systems are required to prevent the contribution to actual or potential SSOs, the City Engineer may serve notice on the discharger to implement such improvements. Such notice may include prohibitions against unauthorized discharges, timetables and/or deadlines.

(j) Use of unauthorized substances prohibited. No person shall introduce or uses any chemical, biological, enzyme or bacterial agent or substance into a FOG disposal system with the intent to enhance performance and/or reduce maintenance of such system without the specific authorization of the City Engineer. Such prohibition is not intended to preclude the use of commercial drain cleaning substances within plumbing fixtures not tributary to a FOG disposal system unless the director has found that such substances present a general hazard to the sanitary sewer system.

(k) FOG control program. This section implements FOG Control Measures, including identification of potential problem areas, focused cleaning and source control. This section also fulfills the FOG Control requirement as described in the State Waste Discharge Requirements.

Where a discharger is required to install and maintain a FOG disposal system pursuant to the provisions of this division and/or is found to be a potential uncontrolled source of FOG, the City Engineer may require that the discharger develop and implement a FOG control program. Where required, such a program is subject to the approval by the City Engineer and may be included as a part of the conditions and limitations of any permit issued pursuant to this division. Such a program may be required to include but is not limited to the following provisions:

(1) A plan and schedule for the education and training of personnel or employees that may dispose of FOG containing effluent to the sanitary sewer system.

(2) The development of source control measures to minimize the discharge of FOG to the sanitary sewer system and maximize the efficiency of any required FOG disposal system and/or GRD.

(3) A plan and schedule for the removal and legal disposal of FOG removed from effluent by a FOG disposal system and/or GRD. When so required by the City Engineer, such a plan and schedule may include the maintenance of a log record detailing cleaning, repair, inspection, accidental spill and disposal events in connection with the system or device. The City Engineer shall have access to any required log during reasonable business hours and may specify a time period during which such a log is maintained.

(4) The City has the legal authority to prohibit discharges to the sewer system and identify measures to prevent SSO's and blockages caused by FOG per this chapter.

(5) The City has the authority to inspect grease producing facilities and possesses the enforcement authority to inspect and enforce this chapter.

(6) Requirements to install grease removal devices (such as traps or interceptors), design standards for the removal devices, maintenance requirements, BMP requirements, record keeping and reporting requirements.

(7) A description of facilities used to store removed FOG prior to disposal and measures taken to prevent accidental and/or uncontrolled discharge of FOG to the sanitary sewer system, sidewalks, parking lots, streets, gutters, storm drains, or other private or public property.

(8) A description of equipment and supplies, including the location of such materials, available for the cleanup of accidental and/or uncontrolled spills of FOG or similar materials.

(9) The City has the authority to inspect grease producing facilities, enforcement authority and may inspect and enforce this chapter.

(10) The posting in a conspicuous place of notification requirements to the City Engineer or other specified entity in the event of any accidental and/or uncontrolled spill of FOG or similar materials that leave or may be carried off the discharger's premise.

(11) The City has the authority to identify a discharger responsible for FOG blockages and establish, develop and implement source control measures for all sources of FOG discharged to the sanitary sewer system per this chapter.

(12) The City will develop and implement source control measures for all sources of FOG discharged into the City's sanitary sewer system for each discharger identified in (11) above.

(l) Minimum standards: City Engineer may develop. The City Engineer may develop minimum standards for the performance, construction, installation and maintenance of FOG disposal systems, gravity grease interceptors, GRDs, hydromechanical grease interceptors, and/or components associated with such devices.

(m) Food service establishments: Operating permit required. Where the City Engineer has determined that installation of a FOG disposal system at a food service establishment is necessary to protect the sanitary sewer system, such installation shall be subject to plan review and operating industrial waste disposal permit requirements pursuant to this Ordinance. Each separate system connected to the public sewer system shall require a separate permit. The City Engineer may authorize multiple food service establishments to discharge through a single FOG disposal system provided each establishment enters into an agreement with a single entity that maintains the device including continuous maintenance of any permits required for operation of the facility.

(n) Food waste disposal units and dishwashers. Unless specifically required or permitted by the City Engineer, no food waste disposal unit, garbage grinder or dishwasher shall be connected to or discharge into any FOG disposal system. Commercial food waste disposers shall discharge directly into the building's sewage drainage system.

(Ord. No. 18-07, 6-13-2018)

Upon determination that any person is discharging industrial wastewater directly or indirectly to a facility regulated by this Ordinance without a valid permit or upon receipt of an application for a permit for an ongoing discharge, an interim permit shall be issued by the City Engineer to allow the continuation of such discharge during the application review period, subject to such conditions, limitations, restrictions, and other provisions or requirements which the City Engineer determines are necessary or advisable to protect the county sewage collection system and to assure compliance with all federal, state and local laws and that the continuation of such discharge will not be detrimental to the public health and safety. This section shall not be interpreted as requiring the issuance of an interim permit for an illicit discharge. An interim permit is revocable by the City Engineer at any time. Any person whose interim permit is revoked shall immediately cease and desist all unpermitted discharge of industrial waste. Unless revoked by the City Engineer, the interim permit shall be enforceable until such time as a permit is issued or denied by the City Engineer and shall be subject to annual inspection fees pursuant to Section 6-13.30. The discharger shall immediately comply with all of the provisions and requirements of such interim permit, and if the discharger has not already applied for a permit, shall apply for a permit within thirty (30) days from the issuance of the interim permit.

(Ord. No. 18-07, 6-13-2018)

Any permittee or discharger required by the City Engineer, by permit or otherwise, to engage in periodic, stand-alone, backup, follow-up, compliance or confirmation monitoring or sampling of a discharge shall notify the City Engineer by telephone, or other authorized means, at least forty-eight (48) hours in advance of any monitoring or sampling to be done. Prior to the commencement of any sampling or monitoring, the City Engineer may request that the permittee furnish the City Engineer a split sample and all supporting data. Notification is not required for internal monitoring and sampling by a discharger for the purpose of process and pretreatment controls unless so requested by the City Engineer. However, such procedures, results and records shall be made available to the City Engineer upon request. Sample acquisition and monitoring shall be performed at a location or sampling point as designated in any permit or as specified by the City Engineer. The City Engineer may require installation of a secured sampling facility to be designated as the sampling point. Sampling and analysis shall be performed in accordance with the techniques prescribed in 40 CFR 136 and amendments thereto. Dischargers to a public sewer system subject to an approved pretreatment program administered by the City Engineer shall submit to the City Engineer, at minimum, all parameters required by 40 CFR 403.12 as may be amended unless otherwise directed. Each permittee, regardless of industrial waste disposal method, shall submit to the City Engineer, certified under penalty of perjury by the permittee, its all required monitoring and sampling reports or other requested data within the times specified in the permit.

(Ord. No. 18-07, 6-13-2018)
