Fats, Oils, and Grease (FOG) Policy 1.0 Purpose

The purpose of this policy is to minimize the loading of animal/vegetable fats, oils, and grease (FOG) entering the Buckskin Sanitary District (BSD) wastewater collection system and Waste Water Treatment Plant (WWTP). FOG can contribute to sewer blockages, causing sanitary sewer overflows and backups, and can interfere with equipment at the WWTP.

BSD sets forth requirements for users and enables the Buckskin Sanitary District to comply with all applicable state and federal laws, including the Clean Water Act (33 United States Code §1251 et seq.) and the General Pretreatment Regulations (40 Code of Federal Regulations, Part 403).

BSD administers the permitting process which is to be adhered to when designing, installing, and/or modifying any portion of a sanitary sewer.

Users, to which this policy applies, as identified in Section 2.2, shall comply with all requirements listed in Section 5.0. The user shall permit inspections by the District with or without notice for the purposes of determining applicability and/or compliance with this policy.

5.0 Requirements for Control Measures

This section describes the requirements for all applicable users. Prior to purchasing a business or signing a lease for a space, it is recommended the user contact the District with questions about their requirements. This can help users avoid costly mistakes or oversights. Each facility must obtain written approval from the BSD for the installation of any type of pre-treatment device, including all GGI’s and traps. In order to obtain approval, a plumbing permit must be obtained. Once the permit and plan review process has been completed, the plans examiner assigned to review your plans shall obtain written approval from the District Manager. Contact BSD at (928) 667-7197 for further information on obtaining plumbing/building permits. 1. Food Service Establishments:

a. New Food Service Establishments

i. All new establishments that involve food preparation with the potential

to discharge FOG, are to have a properly sized exterior GGI installed for the kitchen wastes.

ii. The GGI must meet the minimum requirements set forth in Section 5.3 below and are to be reviewed and approved by the District.

5

iii. Registration of the GGI shall be completed prior to its installation. Forms for registration will be provided for use.

b. Existing Food Service Establishments:

i. With GGI’s:

1. These establishments shall be required to register their grease

control devices within 90 days of the effective date of this program. Forms for registration will be provided for use.

2. Upon any renovation activities which enlarge the seating capacity, alter the food preparation area or significantly change the type of foods prepared, a review of the existing GGI will be made by the District to ensure it is of proper size for the proposed renovation. If required, a new properly sized unit meeting the minimum standards set forth in Section 5.3 below, shall be installed to handle the increase in flows. Registration of the new GGI shall be completed prior to its installation. Forms for registration will be provided for use.

ii. Without GGI’s:

1. May remain status quo unless visual inspection of the downstream sewer lines notes a problem with the build-up of grease. In those cases:

a. Where there is available space, a properly sized exterior GGI meeting the minimum requirements set forth in Section 5.3 below, reviewed and approved by the District having jurisdiction, shall be required. The GGI is to be installed within three (3) months of notification by the District. Extensions to the three-month installation requirement may be granted by the District for proper cause, as long as progress is being made towards the installation. Registration of the grease control devices shall be completed prior to their installation.

b. Where no GGI’s are provided, a service charge will be added to the routine sewer bill to address routine maintenance of the sewer lines in order to prevent reduced line capacity and blockage.

2. Upon any renovation activities of an existing food service

establishment which enlarge the seating capacity, alter the food

6

preparation area or significantly change the type of foods prepared, the above requirements contained in b.(ii)(1) of this section of the program shall be adhered to, based on the space available.

c. Existing structures renovated to contain New Food Service

Establishments:

The above requirements contained in b. (ii)(1)(a) or (b) of this section of the program shall be adhered to, based on space available.

5.1 Plan Reviews

The user and owner of the property, business, or industry or an authorized representative of the user must contact the District for purpose of obtaining a plan review. The plan review shall determine the need, size, location and other requirements of the GGI required to control discharges. The review of such plans and operating procedures shall in no way relieve the user from the responsibility of modifying such facilities as necessary to produce a discharge acceptable to the District in accordance with this Policy and the Engineering Standards of the District. Plans are required to be submitted for approval prior to any of the following:

• Sale or transfer of ownership of the business

• Change in trade name under which the business operated,

• Change in the nature of services provided that affect the potential to discharge FOG, and/or

• Remodeling of the facility that may result in an increase in flow or FOG loading or that otherwise requires the facility to submit plans or specifications for approval through a building or zoning department, or any other formal approval process of a city, county or other jurisdictional agency.

All plans submitted to the District must show the location of the GGI, include dimensions of the GGI and plumbing, show connections to all plumbing fixtures, include the sizing calculation in accordance with Section 5.3, and include documentation of manufacturer ratings for flow from plumbing fixtures if used in the sizing calculations.

5.2 Garbage Grinder / Disposal

Except for domestic sources, users shall not install or replace equipment designed to convert garbage or solid waste into liquefied waste and introduce such waste into the sanitary system by means of garbage grinder/disposal. Disposal of garbage and solid waste shall be disposed of as solid waste.

The liquefied waste does not easily pass through the interior piping to the GGI. With time, a gelatinous layer on the interior wall of the piping occurs, which leads to pest

7

infestation. The additional organic materials introduced into the interceptor increase septic conditions. The result is the production of hydrogen sulfide gas that is considered a nuisance. The introduction of pollutants which result in the presence of toxic gases, vapors, or fumes within the sanitary system in a quantity that may cause acute worker health and safety problems is also prohibited. 5.3 Gravity Grease Interceptors (GGI)

Gravity Grease Interceptors (GGI) shall be required for all food preparation establishments which would contribute or cause to contribute, directly or indirectly, any wastewater which contains oil or grease, including but not limited to, restaurants, hotel kitchens, bars, cafeterias, cafes, markets, and fast food outlets. Additionally, grease interceptors shall be required for all schools, fraternal organizations, churches, hospitals, and daycare centers which have the capability to engage in food preparation. Interceptors shall comply with and conform to the 2006 International Plumbing Code and any amendments thereto as approved and adopted by La Paz County, PDI G101, ASME A112.14.3 or A112.14.4 and shall be installed per manufacturer’s instructions. All sinks, floor drains, floor sinks, mop sinks, disposals, dishwashers and other plumbing fixtures in kitchens, bars, bussing stations, and other food service areas into which wastewater containing FOG may be introduced must be connected to the GGI. Water closets, urinals, and other plumbing fixtures conveying human waste shall not drain into or though the GGI. Each business establishment for which a GGI is required shall have a GGI serving only that establishment. Common or shared GGI’s are not permitted. The District may grant a variance for a common or shared GGI if it is pre-existing. All GGI’s and associated plumbing shall be installed by a licensed plumber or contractor. All GGI’s must have two compartments separated by a baffle wall. The primary compartment shall have a volume equal to two thirds of the total capacity, and the secondary compartment shall have a volume equal to one third of the total capacity. Each compartment shall be accessible by a traffic rated manhole above the inlet and outlet piping with a minimum diameter of 24 inches. Manholes covers may not be locked, or otherwise fastened in place such that access is restricted. All plumbing shall be compatible with food service wastewater, such as PVC. A sampling-T with a removable cap shall be placed at the outlet end of the GGI to allow sampling of effluent. The top of the sampling-T shall be no more than one foot below grade. In order to maximize retention time in the primary chamber, the bottom of the inlet piping shall extend down 25% of the total water depth. The bottom of the outlet piping must extend down within 12 inches of the base of the GGI. Flow from the primary to the secondary compartment shall be through a 90 degree elbow bend, or similar device equivalent in cross sectional area to the inlet piping into the GGI, and shall extend down in the primary compartment of the GGI with a height above the base between 9 and 12 inches. Support brackets are required for inlet and outlet piping. Clean

8

outs and venting shall be PVC pipes. Vents shall be independent of any other building venting system and shall be in accordance with local building codes. Refer to Exhibit 1 for a diagram of a GGI. Requirements for GGI’s

• A minimum of 500-gallon capacity, 2-chamber concrete container. Fiber glass and/or other type material must be approved by the District Manager.

• A maximum of 2500-gallon capacity.

• When calculated to have a capacity of seven hundred fifty (750) gallons or more, the interceptor must have three (3) chambers, each with a man-way.

• Installed with a two-way clean-out within five (5) feet before and five (5) feet after the interceptor.

• Constructed with the appropriate traffic rated cover. The cover(s) must not be marked with any wording indicating it is owned by the BSD.

5.3.1 Sizing method based on pipe diameter size and slope

When the final configuration of fixtures in a facility is not known or to allow for additional fixtures in the future, this method shall be used or to size the interceptor for the maximum flow that the drain line from the facility can carry.

5.3.2 Procedure for sizing GGI

The table below is provided to show the standard formula in steps for sizing grease interceptors to suit requirements of specific fixtures. An example of this sizing formula application is included to illustrate the steps.

Steps Formula Example 1 Determine cubic content of fixture.

Multiply length x width x depth. (In Inches)

A sink 48’ long by 24” wide by 12” deep. Cubic

Content

48x24x12=13,824 cubic

9

inches.

2 Determine capacity in gallons. 1 gallon=231 cubic inches

Content in gallons. 13,824 / 231 = 59.8 gallons.

3 Determine actual drainage load. The fixture is normally filled to about 75% of capacity with water. The items being washed displace about 25% of the fixture content, thus actual drainage load = 75% of fixture capacity.

Actual drainage load 0.75 x 59.8 x = 44.9 gallons

4 Determine flow rate and drainage period. In general, good practice dictates a 1 minute drainage period: however, where conditions permit, a 2 minute drainage period is acceptable. Drainage period is the actual time required to completely drain the fixture. Flow rate = Actual drainage load / drainage period

Calculate flow rate For 1 minute period: 44.9 / 1 = 44.9 gpm For 2 minute period: 44.9 / 2 = 22.5 gpm

5 Select interceptor. From Table 1 below, select interceptor which corresponds to the flow rate calculated. Note: select next larger size when flow rate falls between two sizes listed.

Select interceptor. For 1 minute period: 44.9 gpm requires PDI size 50. For 2 minute period: 22.5 gpm requires PDI size 25.

5.3.4. Dishwashers

A separate grease interceptor is recommended for each commercial dishwasher. The size of the interceptor is determined by the GPM discharge rate of the dishwasher as specified by the manufacturer. Select proper interceptor of equivalent or next higher rate from table 5.3.2.

5.3.5. Multiple Fixtures

Where multiple fixtures are served by a single interceptor calculate the interceptor size per section 5.3.1 or, calculate the capacity of each fixture and total the fixture capacities up, or establish the total capacity of the maximum number of fixtures that may be drained simultaneously. Then using the GPM capacity calculated proceed with sizing of the interceptor to the nearest PDI size, larger than the calculated capacity based on a one minute or two minute drain down time. Common or shared GGI’s are not permitted unless a variance is granted. Any common or shared GGI’s must be sized appropriately for each individual restaurant and the sizes must be added together to obtain the final GGI size. Common or shared GGI’s may be reevaluated for proper sizing and capacity as facilities change business operations, practices, or owners or tenants.

5.3.6 GGI Location

Each GGI shall be so installed and connected that it shall be at all times easily accessible for inspection, cleaning, pumping, and maintenance. Each GGI manhole cover shall be readily accessible and safely removable for servicing and maintaining the GGI in good working condition. The use of ladders, the removal of bulky equipment, or any other circumstances that impedes safe access in order to service or inspect GGI shall constitute a violation of accessibility. GGI are not permitted to be located in parking spaces or drive-thrus. GGI shall not be installed in any part of a building where food is handled. Location of all GGI shall be shown on the approved building plan.

5.3.7 GGI Maintenance

GGI’s shall be maintained, at the expense of the user, by regularly scheduled cleaning so that they will properly operate as intended to efficiently intercept the FOG from the user’s wastewater and prevent the discharge of said materials into the District’s wastewater collection system. A GGI shall be serviced at a minimum of every 90 days or more frequently as needed to ensure that the total depth of FOG and settled

12

solids does not exceed twenty five percent (25%) of the GGI’s total capacity or the capacity of an individual compartment. The District may allow a less frequent pumping schedule if the user can demonstrate the GGI does not need to be pumped every 90 days. All users are required to structurally maintain all components of their GGI’s as per the design requirements in accordance with Section 5.3 of this document. Maintenance of GGI shall be done in a workman like manner only by a business or professional normally engaged in the servicing of such plumbing fixtures. Partial removal of contents (i.e., removal of grease layer, oil layer, or sludge layer) is not allowed. Contents removed from GGI’s shall be hauled offsite and disposed of properly. Under no circumstances shall GGI contents be reintroduced to the sanitary sewer system. The user must take reasonable steps to assure that all waste is properly disposed of at a facility in accordance with federal, state and local regulations (i.e., through certification by the hauler included on the waste manifest or trip ticket for each load.) All records, receipts, and manifests of GGI maintenance, removal of GGI contents and of offsite hauling of FOG waste shall remain onsite and accessible for review by the District for a minimum of three (3) years. The District may require a user that falls under the provisions of this policy to submit copies of all records, receipts, and manifests of GGI and/or WGB maintenance, removal of GGI and/or WGB contents and of offsite hauling of FOG waste. In the event a GGI is not properly maintained by the user, the District may authorize such maintenance work to be performed on behalf of the user. The cost of such maintenance shall be billed directly to the user and shall become part of the charges due and owing to the District and shall constitute a lien against the property until paid in full. Biological treatment of enzyme treatment shall not be a substitute for the servicing of the GGI. Use of enzymes or any other products to emulsify FOG is prohibited.

5.3.8 GGI Closure

The District may determine that a GGI is no longer necessary. This may occur when the wastewater flow through the GGI is significantly lower to due changes in kitchen practices. A lack of flow through the GGI often causes the GGI to become septic producing noxious sulfide gases, serious odor problems, and other potential health and safety hazards. Abandoned GGI’s shall be closed by:

13

• Complete removal of GGI contents (oils, grease, solids, water, etc.), generally performed by a grease interceptor service company.

• Installing of a direct pipe connection from the inlet to the outlet,

• Filling of the empty GGI with an appropriate fill material such as sand, and approved by the County Health Dept. and/or any applicable jurisdictional agency

• Securing the opening(s) to the GGI (e.g. cement, etc.) Inspections of closure activities may be required by the District

5.3.9 Facilities with Existing GGI’s

Some facilities may have GGI in place. An existing GGI may be undersized for a user according to the sizing requirements of Section 5.3.1. The District may approve a new user or a user who is required to submit plans for review under Section 5.1 to use the existing GGI if the District determines it can adequately protect the sanitary sewer from FOG. The existing GGI must have two chambers and be retrofitted to meet the requirements of Section 5.0.

5.4 Grease Traps

Grease traps are allowed only when there are four (4) or fewer than four (4) fixtures used for food preparation. Any facility installing a dishwasher shall install a grease interceptor. For the purpose of sizing a grease trap, a fixture means the entire unit; e.g., a 3-compartment sink is considered one unit. Grease traps must be installed as follows:

1. A grease trap shall be installed whenever a 3-compartment sink is required by La

Paz County.

2. The minimum size grease trap to be installed shall be rated no smaller than fifty (50) gallon-per-minute with a 100-pound grease capacity.

3. A flow restriction device valve shall be installed upstream of the grease trap and

vented properly. If placed below floor level, the flow restriction valve must be installed in a manner which allows for inspection and maintenance. If the flow restriction valve is not accessible for inspection and maintenance purposes, the installation will not be approved.

14

The following are examples of those facilities that may install a grease trap in lieu of a gravity grease interceptor (GGI):

Delicatessens, sandwich shops, coffee shops, and pizza take-out facilities (only pizza being served), and ice cream parlors. These facilities must have limited preparation of pre-cooked meals/food, minimal cooking, food preparation and where minimal cleanup from food service would take place.

5.5 Chemical or Bacteriological Additives in Interceptors and/or Traps

The BSD recommends that no chemical or bacteriological additive be introduced into the grease interceptors and/or traps. Although these products have beneficial

15

uses in the correct conditions, contact time in pretreatment device, upstream use of disinfection products required by the health department, temperature of effluent flow, and contact with wetted surface area of piping should be considered prior to use of such products. At no time shall any additive be introduced that causes emulsification and/or saponification to occur.

5.6 Cleaning Methods and Requirements

5.6.1 Grease Traps

The contents of the trap shall be pumped at least every 30 business days. No partial pumping shall be allowed. All liquid shall be removed from the trap and placed into a suitable container for disposal. The contents of the trap and any wash water shall not be pumped back into any private sanitary sewer, pretreatment device, or any other connection leading to the BSD sanitary sewer system

The sidewalls, bottom, and permanently installed baffles shall be scraped to remove all fats, oils, grease, and solids. Trap with removable baffles – the baffle(s) shall be removed, cleaned, inspected, and then re-installed. The cover gasket shall be inspected. If repairs are necessary, they must be made prior to placing the trap back into service.

Self-cleaning of grease traps is allowed. Prior to self-cleaning a trap, the owner must produce a written standard operating procedure and submit to the County Health Department for approval. A Health Department Inspector will review the procedures and conduct an inspection to review the procedure as the trap is being cleaned. Written documentation will be provided if the process in place is deemed inadequate. Disposal of the trap contents shall be placed into a suitable storage container and disposed of into a solid waste container only if the trap owner has written permission from the solid waste disposal firm and owner of the solid waste container if the trap owner is not the owner of the solid waste container.

If not self-cleaning, the owner of the trap must hire a non-hazardous liquid waste hauler (NHLWH) approved by La Paz County Public Works Department, Solid Waste Section and permitted by ADEQ and assigned an ADEQ ID number.

The NHLWH shall remove all liquid and solids from the trap and pump into the permitted vehicle. The sidewalls, bottom, and baffles shall be scraped to remove all fats, oils, grease, and solids. Trap with removable baffles – the baffle(s) shall be removed, cleaned, inspected and then re-installed. The cover gasket shall be inspected. If repairs are necessary, they must be made prior to placing the trap back into service.

16

The contents of the trap and any wash water shall not be pumped back into any private sanitary sewer, pretreatment device, or any other connection leading to the BSD Sanitary Sewer System.

5.6.2 GGI

The contents of the interceptor shall be pumped at a minimum of at least every 90 business days or more frequently if the solids content reaches 25% of the interceptor volume, or when the final compartment contains more than three (3) inches of grease. At the time of cleaning, all liquid and solid contents shall be removed from ALL compartments of the interceptor. The contents of the interceptor shall be pumped into an approved NHLWH vehicle. The NHLWH shall scrape and rinse all side walls, baffles, and bottom of the interceptor. The rinse water and remaining solids shall be pumped into the approved NHLWH vehicle. Any damage caused by the NHLWH and/or observed by the NHLWH must be reported to the BSD at 928-667-7197 at the time the damage is caused and/or observed. Notification to the owner of the interceptor is to also be made immediately after notifying the BSD.

Only full pump outs are authorized. Skimming and partial pumping shall NOT be conducted. The contents shall not be pumped back into any sanitary sewer. The contents of the interceptor and any wash water shall not be pumped back into any sanitary sewer, pretreatment device, or any other connection to the BSD Sanitary Sewer System.

After cleaning, the interceptor shall be filled with fresh water only, provided by normal facility discharge from permanently installed fixtures. The use of water hoses to fill the trap may create a backflow hazard, if at any time the hose is allowed to be placed below the flood plain of the interceptor.

The pumping frequency shall be at a minimum of every 90 days. Depending on the use and size of interceptor, more frequent pumping may be required.

5.7 Best Management Practices (BMPs)

The purpose of BMPs is to minimize the discharge of FOG into the District’s Sanitary Sewer System. The following BMPs shall be implemented by nondomestic users to whom this policy applies. This includes employee training and kitchen practices that are essential in minimizing FOG discharges:

• Installation of drain screens. Drain screens shall be installed on all drainage pipes in food preparation areas. This includes kitchen sinks, floor drains and mop sinks. Drain screens shall be cleaned as needed.

17

• Segregation and collection of waste cooking oil and grease. All waste cooking oil and grease shall be collected and stored properly in waste grease bins (WGBs) or similar devices. Such WGBs shall be maintained to ensure that they do not leak and are weather tight. WGBs shall be pumped before they are 90% full by a licensed nonhazardous liquid waste hauler (NHLWH) or an approved recycler to dispose of waste cooking oil.

• Disposal of food waste. Food wastes shall be disposed of directly into the trash or garbage and not into the drain.

• Employee training. Employee training shall be provided as part of the normal orientation process and annually thereafter including, at a minimum, the following subjects:

o How to scrape excess food into the garbage and “dry wipe” pots, pans, dishware and work areas before washing to remove grease,

o The location, use, and disposal of absorption products to clean any spills under fryer baskets and other locations where grease may be spilled or dripped,

o How to properly dispose of grease or oils from cooking equipment into a grease receptacle without spilling.

o The need for and cleaning of drain screens, and o Proper clean techniques of cleaning product or other chemical

spills, if safe to do so. o Training shall be documented and employee signatures retained

indicating each employee’s attendance and understanding of the practices reviewed. Training records shall be made available for review at any reasonable time by the District.

o Kitchen Signage. Signs shall be posted above all sinks prohibiting the discharge of oil, grease, and food waste down the drains.

5.8 Spill Prevention

All users are required to have measures in place to control unwanted discharge to the sanitary sewer. Chemicals, cooking oils, and other liquid products must be stored away from drains or within a containment to reduce the potential for spills reaching the sanitary sewer drainage system.

5.9 Variances

A variance as to the requirements of this policy for existing users may be granted by the District for good cause. The user has the burden of proof of demonstrating through data and other information why a variance should be granted. The granting of any variance shall be at the discretion of the District and requires the approval of the District Manager. If a variance is granted, the user shall institute BMPs and other mitigation measures as determined by the District.

18

6.0 Recordkeeping

All food service establishments shall maintain an inspection and maintenance log for each GGI. The inspection log is to include date of the inspection, who conducted the inspection, an indication if maintenance or cleaning is necessary and any other observations/comments. The maintenance log is to include the date of maintenance and/or cleaning, the name of the person/company providing maintenance and/or cleaning, who observed the maintenance/cleaning and the volume removed with each cleaning. If grease is hauled for recycling, the record shall contain the date it was hauled, the company providing the hauling and the volume hauled. All records shall be maintained on site for a minimum of three (3) years and are to be made available for inspection by the District, if requested.

7.0 Inspections and Sampling

As deemed necessary, the District having jurisdiction may conduct inspections of food service establishments which discharge into the sanitary sewer collection system. The purpose of the inspections will be to determine if the facilities are complying with the terms of this program and, if applicable, their wastewater pretreatment permits. Owners or their occupants shall allow the District access at all reasonable times to all areas of the facility that contribute FOG for the purpose of inspection, records review and sampling. In addition, the District shall have the ability to set up sampling devices on the property to verify effluent quality. Denial of access for the purpose of inspections, records review and/or sampling will be deemed a violation of this program and/or permit. Any unreasonable delays in allowing the inspections may also be considered access denial and thus a violation. Based on the results of sampling, surcharges may be applied to the facility’s sewer bill as per Buckskin Sanitary District’s Sewer Use Ordinance and Fee Schedule on high strength waste.

The BSD will provide written notices to all facilities following inspections of a user’s improvement is required. For those facilities for which improvement is required, the BSD may assist the facility in the identification of the source/cause of the inadequacies noted on the written report. Once the sources/causes of the inadequacies are identified, the BSD will request that the facility correct the inadequacies as soon as practicable. In the case of cleaning, the action shall be within five working days. For mechanical correction such as plumbing/equipment change, the BSD and facility will reach a consensus, but the correction period shall not be longer than 60 days from the date of written notice. Those facilities determined to be in continued violation of BSD requirements, and of this policy, will be provided a written notice of violation (NOV). Follow-up inspections will
