EASEMENT ACCESS PROCEDURE
Sewer Maintenance SOP
EASEMENT ACCESS PROCEDURES
AFTER RECEIVING A SEWER COMPLAINT FROM CITY HALL OR DISPATCH… Maintenance crew arrives at address and knocks on door.
IF RESIDENT IS HOME:
Inform resident that there is a need to inspect the sewer system located in the sewer easement on their property.
Proceed to yard and perform required maintenance activities as neatly as possible. Try not to disturb landscaping.
Replace manhole cover and remove all signs of activities, equipment, debris, etc. Ensure gate(s) are shut on the way out.
Inform resident(s) of the condition encountered, work completed and if there is any necessary follow-up. If so, provide an anticipated date and time when crews need to return. If necessary, identify the location of the upstream and/or downstream manhole(s) in the underground map book. Proceed to that residence and start process again.
If resident refuses entry:
Hand the resident the “Access Required” door hanger and allow them a moment to read and u
nderstand the City ordinance that residents must provide unobstructed access to public mainlines and manholes located on private property. If necessary, hand resident manager’s business card and wait for resident to call.
If resident STILL refuses entry:
Return to yard and ask supervisor to mail an “Access Ordinance” letter to the resident. The letter should provide a date and time upon which crews will return and require access.
Daytime: IF NO ONE IS HOME AND YARD IS ACCESSIBLE:
Fill out the “Access Required” door hanger explaining that there was a need for sewer crews to access the public sewer mainline/manhole on the property. Leave on the door knob(s) of doors expected to be used by returning residents.
Go to gate and call out (make noise) in case there is a dog in the yard. Enter yard and proceed with maintenance activities as neatly as possible. Try not to disturb landscaping.

SPILL VOLUME CALCULATION
The purpose of this worksheet is to capture the data and method(s) used in estimating the volume of a spill.
Since there are many variables and often unknown values involved, this calculation is just an estimate.
Additionally, it is useful to use more than one method, if possible, to validate your estimate.

Measured Volume Method (this may take several calculations as may have to break down the odd shaped spill to rectangles, circles, and polygons)
If the entire spill is settled in one area, calculate the volume of spill in feet (L' X W' X D') and convert to gallons (X7.48 for gallons in a square area, and X.785 for gallons in a circular area). It is important when guessing depth to measure, if possible in several locations and use an average depth.

5. Upstream Connections Method
If you are dealing with a spill that has been running into a storm drain, you must estimate the gallons by: the amount of the spill times the number of upstream connections on the receiving line (200 gal. per household per 24 hr) and estimate the time that the flow has been occurring. Each residence contributes about 240 gallons per day or about 10 gallons per hour.
Multiply the number of residences by 10 and by the number of hours. This gives you the number of gallons.
EXAMPLE A: If you have a line with 6 houses on it and it has been spilling for 24 hours :
6 houses x 200 gallons per house per 24 hours = 1,200 gal.
EXAMPLE B: If you have 60 houses on a line that has been overflowing for 4 hours :
60 houses x 10 gallons per house per hour x 4 hours= 2,400 gal.
Pump Station Method
If the flow is coming from a pump station, use the previous day's (same weather) flow and pump capacity to estimate the flow.

CALCULATION AND ESTIMATION METHODS
Sewer Maintenance Spill
Calculation and Estimation Methods
Outlined in this document are three methods that are most often employed for estimating the volume of sanitary sewer spill. The City staff preparing the estimate should utilize the most appropriate method for the sewer spill in question and use the best information available.
Method 1: Eyeball method
The volume of small spills can be estimated using an “eyeball estimate”. To use this method imagine the amount of water that would spill from a container listed on the table below. A jug contains 1 gallon, a bucket contains 5 gallons, and a drum contains 55 gallons. If the spill is larger than 55 gallons, try to break the standing water into 55 gal drums and then multiply by 55 gallons. This method is useful for contained spills up to approximately 220 gallons.

Method 2: Measured Volume
The volume of most small spills that have been contained can be estimated using this method.
The shape, dimensions, and the depth of the contained wastewater are needed. The shape and dimensions are used to calculate the area of the spills and the depth is used to calculate the volume.
Common Shapes and Dimensions
Steps for Volume Calculation
Step 1 Sketch the shape of the contained sewage (see figure above).
Step 2 Measure or pace off the dimensions.
Step 3 Measure the depth at several locations and select an average.
Step 4 Convert the dimensions, including depth, to feet.
Step 5 Calculate the area in square feet using the following formulas:
City of San Mateo
Public Works Department
Environmental Services Division
SPILL EMERGENCY RESPONSE PLAN SPILL
CALCULATION AND ESTIMATION METHODS
Rectangle: Area = length (feet) x width (feet)
Circle: Area = diameter (feet) x diameter (feet) x 0.785 Triangle: Area = base (feet) x height (feet) x 0.5
Step 6 Multiply the area (square feet) times the depth (in feet) to obtain the volume in cubic feet.
Step 7 Multiply the volume in cubic feet by 7.5 to convert it to gallons Method 3: Duration and Flowrate
Calculating the volume of larger spills, where it is difficult or impossible to measure the area and depth, requires a different approach. In this method, separate estimates are made of the duration of the spill and the flowrate. The methods of estimating duration and flowrate are:
Duration
The duration is the elapsed time from the time the spill started to the time that the flow was restored.
Start Time: The start time is sometimes difficult to establish. Here are some approaches:
1. Local residents can be used to establish start time. Inquire as to their observations.
Spills that occur in rights-of-way are usually observed and reported promptly. Spills that occur out of the public view can go on longer. Sometimes observations like odors or sounds (e.g. water running in a normally dry creek bed) can be used to estimate the start time.
2. Changes in flow on a downstream flowmeter can be used to establish the start time.
Typically the daily flow peaks are “cut off” or flattened by the loss of flow. This can be identified by comparing hourly flow data during the spill event with flow data from prior days.
This method will likely only be effective with consistent weather.
3. Conditions at the spill site change over time and can be used to establish the start time.
Initially there will be limited deposits of toilet paper and other sewage solids. After a few days to a week, the sewage solids form a light-colored residue. After a few weeks to a month, the sewage solids turn dark. The quantity of toilet paper and other materials of sewage origin increase over time. These observations can be used to estimate the start time in the absence of other information. Taking photographs to document the observations can be helpful if questions arise later in the process. This method is valid for spills that have been occurring for a long time and may be used in conjunction with either of the above methods.
4. It is important to remember that spills may not be continuous. Blockages are not usually complete (some flow continues). In this case the spill would occur during the peak flow periods (typically 10:00 to 12:00 and 13:00 to 16:00 each day). Spills that occur due to peak flows in excess of capacity will occur only during, and for a short period after, heavy rainfall.
End Time: The end time is usually much easier to establish. Field crews on-site observe the “blow down” that occurs when the blockage has been removed. The “blow down” can also be observed in downstream flowmeters.
Flow Rate
The flowrate is the average flow that left the sewer system during the time of the spill.
There are three common ways to estimate the flowrate:
City of San Mateo
Public Works Department
Environmental Services Division
SPILL EMERGENCY RESPONSE PLAN SPILL
CALCULATION
AND ESTIMATION METHODS
1. The San Diego Manhole Flowrate Chart: This chart, included as at the end of this appendix, shows sewage flowing from manhole covers at a variety of flowrates. The observations of the field crew can be used to select the appropriate flowrate from the chart. If possible, photographs are useful in documenting basis for the flowrate estimate.
2. Flowmeter: Changes in flows in downstream flowmeters can be used to estimate the flowrate during the spill.
3. Counting Connections: Once the location of the spill is known, the number of upstream connections can be determined from the sewer maps. Multiply the number of connections by 200 to 250 gallons per day per connection or 8 to 10 gallons per hour per connection.
For example: 22 upstream connections * 9 gallons per hour per connection = 198 gallons per hour / 60 minutes per hour
= 3.3 gallons per minute
Spill Volume
Once duration and flowrate have been estimated, the volume of the spill is the product of duration (hours or days) and the flowrate (gallons per hour or gallons per day).
For example: Spill start time = 11:00
Spill end time = 14:00
Spill duration = 3 hours
3.3 gallons per minute x 3 hours x 60 minutes per hour
= 594 gallons

WATER QUALITY MONITORING PROGRAM
WATER QUALITY MONITORING PROGRAM
INTRODUCTION
This Water Quality Monitoring Program supplements the description of City response activities and standard operating procedures to be utilized in the SERP, in the event a sanitary sewer spill exceeds 50,000 gallons and enters surface waters. This program is reviewed periodically and may
be updated as necessary.
SAFETY
Be aware of safety issues and do not subject personnel to unsafe conditions in order to comply with this Water Quality Monitoring Plan. Sampling will not be conducted if there are any concerns regarding field crew safety. These concerns may include heavy rain events, which compromise access points through flooding and swift currents. Thunderstorms will also be avoided when lightning is occurring. Employ the buddy system as required to maximize employee safety when sample collection is required.
ESTIMATION OF SPILL TRAVEL TIME
The following methods are recommended to estimate spill travel time and direction:
• Method 1: Use a velocity probe (such as a Global Water FP111-S Flow Probe). To determine the rate of flow in the surface water or
• Method 2: Visual ft/sec measurement. This may be done by observing or dropping floatable debris in the surface water and timing how long it takes to travel over a measured distance (e.g., 100 feet). Include sections in the surface water where there are bends, bottlenecks, or other characteristics that may slow down the flow. If the first measurement is uncertain, this estimate may be performed three to five times, and the values averaged to determine an estimated travel time.
Either method will provide a means to estimate the distance traveled and identify where the spill may be headed within the waterway.
City of San Mateo
Public Works Department
Environmental Services Division
SPILL EMERGENCY RESPONSE PLAN
WATER QUALITY MONITORING PROGRAM
WATER QUALITY SAMPLING PROCEDURES
• In the event a spill reaches a surface water or (flowing) drainage channel tributary and the volume is estimated as greater than 50,000 gallons, samples are required within 48 hours of first knowing of the release. The purpose of water quality sampling is to determine the nature and extent of the impact of the spill. Note: Water quality sampling should not be given precedence over stopping the spill or protection of public health. • When sampling a spill, collect a minimum of three samples as conditions allow. One sample shall be located 100 feet upstream of the point where sewage entered the waterway. The second sample shall be taken at the discharge location. A third sample shall be taken 100 feet downstream of the point where sewage entered the waterway.
When possible, collect samples from the middle of the waterway where the water is actively flowing.
• Sample for Total Coliform, E. coli, enterococcus, and Ammonia as a minimum. Conduct additional sampling for pH if practical.
• Additional follow-up samples may be required by the County Health Department to confirm the surface water quality has returned to baseline conditions. The timing and location of samples shall be determined through discussions with the County Health Department. Follow-up samples may be used to determine if posting of warning signs should be discontinued (if signs were posted).
• Collaboration with the County Health Department should continue until closure is obtained.
WATER QUALITY SAMPLING EQUIPMENT
The following list describes equipment that should be stocked and readily available for each water quality sampling event.
• Personnel protective equipment including latex/nitrile gloves and eye protection • 3 – 120 mL sterile plastic containers for Bacteria sample collection. • 3 – 250 mL plastic containers preserved with H2SO4 for Ammonia analysis. • 3 – 250 mL plastic containers (for collecting the sample and transferring to the preserved container for ammonia. Also can be used for checking pH, if desired) • 1 – Sample Collection Tool (extension pole with attachment to hold sample bottle) • Cooler with ice packs
• Chain of Custody forms for WWTP Lab, Caltest Labs, and County Health Lab, Ensure that there are adequate quantities of sample containers-kits if there are more than three sample locations.

ample container and fill it under water, if possible, without collecting surface or bottom debris. Pour off excess sample volume so that the container is filled to the 100-mL fill line. Secure the lid and dry the outside of bottle with a paper towel.
5. I mmediately place the filled & labeled sample container inside the cooler with ice or cold packs.
6. R epeat Steps 1 through 5 for each bacteria sample location. Proceed to Section III (after collecting ammonia samples if necessary).
II. Ammonia Sample Collection – Do NOT Dip Sample Bottle into Water Use Secondary Container
1. O ne 250 -mLplastic ammonia sample bottle (containing sulfuric acid as preservative) must be filled at a point 100 feet upstream of where the spill entered the receiving water, one sample collected at a point 100 feet downstream of where the spill entered the receiving water, and a sample where the spill entered the receiving water. USE THE UNPRESERVED SAMPLE CONTAINER (does not contai n
s
ulfuric acid) TO COLLECT THE SAMPLE AND TRANSFER THE CONTENTS TO THE PRESERVED SAMPLE CONTAINER. Sampling personnel must wear gloves and safety glasses while collecting samples for ammonia because of pot
ential contact with sulfuric acid, which is highly corrosive.
2. U se a pen that does not smear when wet to record on the bottle label (1) the s
ample ID*, (2) date and (3) time of sample collection, and (4) the sampler’s initials.

III. Chain-of-Custody & Sample Delivery
1. De p ending on which lab the bacteria samples will be delivered to, complete the appropriate Chain-of-Custody (COC) form for the bacteria samples (either the WWTP Lab or County Health Lab); include the Sample IDs, Date & Time of Sample C
ollection and Sampler’s Name & Signature. Note the approximate upstream and downstream distance in the “Notes” field on the COC if the samples were collected f
rom a distance other than 100 feet.
The COC is a legal document and must be complete.
2. S pecify on the COC the analyses requested for each sample. Each sample should be anal
yzed for: Total coliform, E. coli, and Enterococcus. Each COC is pre-filled for
three samples; add additional lines if more samples were collected.
3. C omplete the Caltest Lab COC form for all samples that will be analyzed for ammonia. Include the Sample IDs, Date & Time of Sample Collection and Sampler’s Name & Signature. Note the approximate upstream and downstream distance in the “Notes” field on the COC if the samples were collected from a distance other than 100 feet.
The C OC is a legal document and must be complete.
4. De liver bacteria samples to the WWTP Laboratory during normal business hours (Mon – Sun 6:30 a.m. to 3 p.m.). If after business hours, deliver to the County Health Lab.
5. A mmonia samples will be picked up by Cal test from the WWTP Lab. A sample r
efrigerator labelled “Caltest Pickup” is in the sample receiving room of the WWTP Lab. Place the labelled ammonia samples in the refrigerator. MAKE SURE THE City of San Mateo

SAMPLE LABELS AND COC ARE COMPLETE. Place the CalTest COC in the clip on the refrigerator door. Call Caltest for a pickup (707-258-4000). The courier will sign the COC when they pick up the samples and leave a copy of the signed COC in the clip.
6. If unable to deliver the bacteria samples to the WWTP Lab, they can be delivered to the San Mateo County Public Health Laboratory at:
225 W.
37th Ave, Room 113. Hours of operation are Mon – Fri 8a m to 5pm.* Have the Lab Analyst sign the COC form & make a copy.
7. Place the signed COC forms (or photocopies) in the spill file.
SAM
PLING COLLECTION BEST PRACTICE
• Collect all grab samples approximately 3’ - 6” below the surface (or if shallower, as close as possible to this depth) to avoid sampling debris or scum from the surface. • Collect the sample in a safe manner in the middle of the flow, against the direction of water flow.
• Photo-document the spill locations.
• Leave approximately one inch of head space in individual sample bottles. Do not overfill. • Once the lid is opened for the individual sample bottle, do not touch the inside surface of the bottle or lid.
• For the sample bottles that contain a preservative, take care to keep the preservation material in the container.
• Immediately place all sample bottles on ice.
SAMPLING TIME CONSTRAINTS
Bacteria samples have a 6-hour (chilled) regulatory holding time. Samples will not be analyzed if the holding time has been exceeded. The WWTP Lab and County Lab need about 30 minutes to set up the tests.
Ammonia samples have a 28-day regulatory holding time. Samples must be maintained at < 6oC (on ice or refrigerated) from the time of collection until receipt by the analytical laboratory. *If the WWTP Lab and County Public Health lab is Closed… If the WWTP Lab or County Health Lab will be opening within 5 hours from the time the samples were collected, keep samples in a refrigerator or in the cooler containing the cold packs/ice and immediately deliver samples as soon as either Lab is open for business.
Otherwise, call the County Health Lab’s After Hours Contact List (starting with #1 – Office/Pager/Cell
) and arrange to meet a lab analyst. They have agreed to meet us at the lab to receive samples during off-hours.

Grease Removal Devices and Maintenance / Records
If you generate grease, you will need a grease removal device (GRD). - A GRD is either a grease trap or a grease interceptor. To stop pipes from plugging, keep your GRD in continuous operation and clean. - At a minimum, clean the device every six months ; or when the combined thickness of the floating fats, oil and grease, and solids layers exceeds 25% of the total depth of the device. Keep a record of GRD cleanings in a logbook or binder for the Environmental Compliance Inspector to review:
- Document the date
- Who performed the cleaning
- How much waste was removed
- Where the waste was deposited
If you hire a contractor to clean the GRD:
- Confirm the work was performed as agreed
- Keep the receipts in a folder as proof of service
Restaurant Operating Practices
Greasy, dirty, water from cleaning the exhaust FILTERS should be drained into the sink connected to the grease trap or interceptor - or disposed of offsite by your contractor. - Water from cleaning the exhaust HOODS is too dirty and should be disposed of offsite by your contractor. Waste oil should be collected in a tallow bin and disposed of by a grease-waste hauling company. To save money on GRD cleaning costs, use dry clean -up methods such as dry wiping with ru bber scrapers and paper towels. These practices reduce the solids and grease load to the GRD:
Scrape off excess food from plates and cookware into the trash.
Wipe the excess grease with paper towels and dispose of the towels in the trash.
Wash plates, pots, pans and utensils.
Keep the ingredients in the bowl, not on the floor! To prevent spills:
- Cover large containers when transporting
- Securely store liquid materials away from floor drains To prevent solids from clogging pipes, keep strainers or screens over floor drains.
Storm Drain Protection
It’s against the law to drain any water into a storm drain from washing floor mats or other equipment. Storm drains lead directly to local creeks and the bay, and are for rain water only. Instead, pour dirty water in the mop sink or an area connected to a sanitary drain.
Don’t throw mop water out the back door! It is illegal to dump mop water to a storm drain.
Put it into a sink or sanitary drain instead.
Keep it clean! Cover your dumpsters and clean your trash enclosure, tallow bins, or barrels to prevent trash and grease waste from getting washed into the storm drain. Don’t rinse spills into the storm drain. Use dry clean-up methods (absorbents/kitty litter for oil spills) or a wet-dry vacuum to clean outdoor spills.

Municipal Code Applicable to
Food Service Establishments
Chapter 7.38 Sanitary Sewer Use
7.38.160. Requirements for Food Service Facilities
(a) The owner of every commercial, industrial, or institutional food service facility, shall install or cause to be installed a pretreatment system for grease removal which meets or exceeds minimum sizing requirements of the Uniform Plumbing Code, by no later than January 1, 2001. The Director shall approve final sizing.
7.38.100 Pretreatment of Industrial Waste
(c) Food service facilities shall have a pretreatment system for grease removal designed to serve all drains that may discharge grease into the sewer, including floor drains.
7.38.120 Specific Discharge Prohibitions
(h) Oil and grease shall not be discharged into the sewer system if average concentration of floatable oil and grease exceeds 20 mg/L, defined as that which is subject to gravity separation at a temperature of 20 degrees Celsius and at pH 4.5; nor shall the total oil and grease concentration exceed 200 mg/L.
7.38.170 Operation and Maintenance of Pretreatment Systems (a) Pretreatment systems shall be inspected and maintained by the user as needed to ensure continuous efficient operation.
(c) A record of all inspection and maintenance activity shall be kept by the user at the facility showing the date of inspection or maintenance, the activity completed, and the disposition of the removed contents, filters cartridges, or other components.
(d) Failure to operate or maintain the pretreatment system in a way so as to ensure optimum efficiency, or failure to keep records of pretreatment system maintenance shall constitute a violation of this chapter.
7.38.210 Waste Discharge Permit
(a) The Director shall require each significant industrial user to obtain a waste discharge permit. (b) The Director may require other users to obtain waste discharge permits as necessary to carry out the purposes of this chapter.
7.38.390 Best Management Practices
(a) Where best management practices (BMP’s) have been established or adopted by the Director for an activity, operation, or facility which may cause a prohibited dischar ge to the sanitary sewer or stor m drain systems, persons undertaking such activity or o peration, or owning or operating such facility shall comply with such requirements as may be specified by the Director in waste discharge permits, compliance directives, printed material, or verbal notice. (Ord. 2006-1 § 1; Ord. 2003-7 § 1) Chapter 7.39 Stormwater Management and Discharge Control
7.39.090 Discharge of Pollutants
(a) Non-stormwater discharges to the City storm drain system are prohibited.
7.39.110 Illicit Discharge
(a) It is prohibited to establish, use, maintain, or continue illicit drainage connections to the City storm drain system, and to commence or continue any illicit discharges to the City storm drain system. This prohibition applies to connections made in the past, regardless of whether made under a permit or whether permissible under the law or practices applicable or prevailing at the time of the connection.
7.39.120 Reduction of Pollutants in Stormwater
Any person engaged in activities, which will or may result in pollutants entering the City storm drain system shall undertake all practicable measures to reduce such pollutants.
Storm drains flow directly into creeks, San Francisco
Bay and the Pacific Ocean without any treatment. Non-
stormwater and other wastes that flow into a storm
drain cause pollution. Food handling facilities can cease stormwater pollution through proper cleanup practices that ensure food particles, oil and grease, litter, wash water and cleaning products flow to interior sewer connections, which ensures the water is treated prior to being released.
NEVER RINSE OUTDOOR
AREA WITH HOSE
Only rain water is allowed down the
storm drains, because storm drains
connect directly to local creeks.
It is the responsibility of your business to use appropriate Best Management Practices (BMPs) to keep wind or rain
from carrying pollution into the street.
GENERAL BEST MANAGEMENT PRACTICES
Keep Dumpster Area Clean
Close dumpster lids.
Routinely inspect dumpster area for cleanliness.
• If dumpsters overfill, consider having more dumpsters, or increasing trash pick-up service.
• Replace leaking or cracked dumpsters.
• If loose waste is on the ground, then sweep up.
Educate all staff on keeping dumpster areas tidy. With
high rates of employee turnover, or when sharing a
dumpster area, post signs or have routine meetings on
proper BMPs.
Cooking Oil & Grease
Store oil and grease properly in permitted tallow bins; never pour oil or grease in the trash, storm drain, street, sinks or floor drains.
Keep tallow bins clean & lids sealed.
Have tallow bin collection scheduled to maintain
adequate storage capacity.
Check rooftop exhaust fans at least monthly. Place tray under exhaust fan shrouds to collect oil; empty weekly at a minimum.
Clean up spills right away (See back of this sheet).
Manage Outdoor Areas (Parking Lots, Outdoor Seating,
Staff Break Areas, Outdoor Storage)
Empty trash bins into dumpster regularly.
Sweep frequently in trash-prone places.
If frequent litter issues, consider adding trash cans.
Place ash trays in cigarette-prone areas.

CLEANING BEST MANAGEMENT PRACTICES
Use Dry Cleaning Methods
Sweep up dust, debris, and trash.
Vacuum floor mats. If water is needed, rinse mats in
dishwasher or mop utility sink. Never wash floor mats
outdoors or allow wash water to flow to outdoor areas.
Do not clean equipment outdoors.
When hiring cleaning companies (e.g. for cleaning hood/roof equipment), make sure the company uses dry cleaning methods. If wet methods are used, block off gutters & use a pump/wet-vac, so no water spills off roof.
Contain and Manage Spills Promptly
Keep a spill kit near high risk areas (e.g. near
oil tallow bins, loading dock). Kit may include:
Barrier/Sock, Storm Drain Inlet Protection;
Absorbent granules or kitty litter, Towels, Pads;
Dustpan, Broom, Gloves, Trash Bags.
Contain the spill and protect nearby storm
drains immediately.
Use absorbents/towels to manage spill. Sweep
up and dispose of properly.
Make sure staff know spill plan and spill kit
location.
BEST MANAGEMENT PRACTICES FOR
FOOD SERVICE FACILITIES
Information for Restaurants | Cafeterias | Grocery Stores | Food Handling Facilities STORM DRAINS VS.
SANITARY SEWERS:
Do your employees know
the difference?
All outdoor drains are storm drains.
Pollution that enters storm drains
flows directly to creeks and San
Francisco Bay or the Ocean, not
treated or properly cleaned.
Indoor drains (such as sink, toilet,
mop sink, kitchen floor drain)
lead to the sanitary sewer system,
which is connected to a wastewater
treatment plant.
Properly cleaning and disposing of wash waters helps prevent pollution.
Mop sinks go to the sanitary
sewer and wastewater
treatment plant.
Sweeping is an
example of a dry
cleaning method.
Never rinse water
down storm
drains.

Prevent Costly Sewer Back-Ups
Information for Apartment Managers
Pouring grease down drains is an important cause of sanitary sewe r backups and overflows in San Mateo neighborhoods. The City of San Mateo Public Works Depa rtment is working hard to maintain the public sewer through intense cleaning efforts, reha bilitation of old sewer lines and education. We need you to protect and maintain your sewer lateral to help prevent the health threat and environmental damage that overflows can cause.
Follow these tips to keep your lines clear of clogs year-round Clean. Clean sewer lines regularly to prevent problems, or step up the number of cleanings if you’re still experiencing backups. The City strongly recommends cleaning at least annually.
Catch and remove . Train maintenance staff to catch and remove the debris that is dislodged during a cleaning. Be sure any plumbers you contact do th e same to assure that you are getting what you pay for. If materials are not removed or simply push ed down the pi pe, you are not solving the problem—you are simp ly paying for it to recur later.
Educate. Remind tenants of the importance of pr operly disposing kitc hen wastes and other materials. Enclosed are some informational pieces that can be distributed to tenants and posted on bulletin boards or trash collection areas. The City can also provide newsletter articles and on-site training upon request. Call us at 650-522-7300 for more information.
Help residents understand how it helps them
It keeps rent low . With too many costly b ackups, you may have to raise rent. The State of California is also stepping up enforcement of sanitary sewer overflows from the multi-family sector, so preparation is the key.
It protects their property. A sewer backup in a dwelling unit causes significant damage to floors and personal property.
It protects human health and the environment . Overflows contaminate yards, creeks and city streets and expose community residents to health and environmental hazards.
What should residents do?
• Pour grease and oil into a lidded container, and place it in the trash. To help solidify the grease, freeze it or add coffee grounds, kitty litter or other absorbent material. • Use paper towels to wipe excess grease from pans and utensils before washing them. • Never put grease, medications, diapers, paper or other objects down drains or toilets.
For more information, please contact Public Works at 650-522-7300 Please
Help Prevent Sewer Backups
and Overflows
Disposal of grease and solid objects down drains and toilets is a leading cause of sanitary sewer backups. Se wer backups may result in raised rents due to increased maintenance costs, as well as possible penalties for property, health, and environmental damages! Help prev ent sewer blockages by taking these steps:
DO NOT PUT GREASE, PAPER TOWELS, DIAPERS,
MEDICATIONS, DISPOSABLE MOPS, OR OTHER
SOLID OBJECTS DOWN SINKS OR TOILETS.
Pour grease into a lidded container and
place it in the trash. To help solidify the
grease, mix the grease with coffee
grounds, kitty litter, paper towels, or other
absorbent materials.
Use paper towels to wipe excess grease
from pans and utensils before washing
them, and dispose the wipes in the trash.
Dispose of diapers, plastics, disposable
mops and wipes, facial tissue and other
solid objects in the trash
. Do not flush any
of these down a drain!
Please do not throw away old medications
down the drain or in the trash. Instead,
drop them off at a collection container
located at the San Mateo Police
Department, 200 Franklin Parkway.

BEST MANAGEMENT PRACTICES FOR FOOD SERVICE FACILITIES
Implement the following work practices as each may apply to your operation to help minimize discharge of FOG wastes to the sanitary sewer system. For more information call the Regulatory Compliance Division at (650) 522-7300.
Drain Screens. Clean drain screens on all
drains in food preparation areas frequently.
Dispose of food solids in trash or food waste
recycling container.
Dish Cleaning. Scrape or wipe fat, oil,
grease and other food residue from
cookware, utensils, etc., prior to
dishwashing. Dispose food waste in trash or
food recycling container. Use detergents,
not soaps (soaps contain oil)
Used Oils and Grease. Collect all used
cooking oils and grease from pots, pans,
and fryers and dispose in designated
container for recycling. Do not dispose
down drain or in trash.
Spill Prevention. Use container with cover
to transfer cooking oils and grease from
kitchen to outdoor storage container. Empty
containers before they are full to avoid spills.
Spill Cleanup. Use absorbents such as cat
litter or paper towels to pick up oil and
grease spills before mopping. Keep spill
cleanup supplies well marked and readily
available.
Fryers. Use absorbent paper under fryer
baskets. Dispose in trash or with recycled
food waste.
Solid Food Wastes. Dispose of food waste
in trash or food waste recycling container,
not in sinks. Transfer a manageable weight
to prevent spill. Use heavy duty or double
clear container bags to help minimize
container odors and leaks.
Liquid Food Wastes. Do not dispose
liquid food, milk shake syrups, batters and
gravy, or other oily or fatty wastes down the
drain. Use materials to absorb liquid and
dispose in trash or food waste container.
Food Grinder. Minimize or avoid use of
food grinder, as food solids can contribute to
clogged drain pipes and/or fill grease traps
and interceptors.
Trash and Recycling Containers. Inspect
trash and recycling containers regularly for
leaks and replace leaking containers
promptly.
Drain Cleaning Chemicals. Avoid use of
emulsifiers or solvents other than typical
dishwashing detergents. Use of drain
cleaning chemicals is not a substitute for the
required physical cleaning of grease traps
and interceptors.
Mats and Range Hood Filters. Dispose of
oily wastewaters from cleaning operations in
drain connected to grease interceptor; or
use professional service that provides
replacement mats and filters and cleans
mats and filters at off-site location.
Grease Traps and Drains. Use
professional service to pump and off-haul
grease trap wastes. Alternatively, collect
skimmed oils, grease and food solids and
dispose of properly.
Employee Education. Post “no Grease”
best practices signs in appropriate work
areas

Waste Discharge Permits for Food Service Facilities
Frequently Asked Questions
Who Needs a Waste Discharge Permit?
Any food store, eating place, or food preparer
that bakes or cooks food on the premises must
apply for a waste discharge permit.
Why these facilities?
Food service facilities commonly generate fat,
oil, and grease (FOG) wastes in the cooking
process. Wastewater from kitchen cleaning
operations typically contains FOG wastes. FOG
wastes can build up in the sewer system, and
result in partial or total blockage of the sewer.
Blockage can result in sewer backups and
overflows.
Why a permit?
Federal and state regulations, as well as
municipal preventive maintenance costs, are
prompting an increased level of sewer system
monitoring, maintenance, and recordkeeping.
The City/District has found that while periodic
inspection of commercial kitchens helps identify
and correct problems, the message about
effectively preventing FOG discharge into the
sewer system is often lost over time. A permit
provides the means to formally convey sewer
discharge requirements and the consequences of
failure to comply with the requirements. The
permit also serves as ready reference to these
requirements that can be referred to by facility
management and staff at any time.
What does the permit cover?
The permit formally conveys the same items that
have been and will be inspected by the
City/District. These include pretreatment system
maintenance procedures and maintenance
records, and proper handling of pretreatment
system waste . The inspector also inspects for
records of cooking grease handling and disposal,
and other practices that affect discharge of FOG
into the sewer system.
What is a pretreatment system?
An under-counter grease trap and outdoor grease
interceptor are examples of pretreatment
systems. These are devices that are required t o
be installed on drain lines that may carry FOG
wastes in the wastewater.
How do I know if I need to install or upgrade
a pretreatment system?
At minimum, any kitchen utensil cleaning sink
or wok range must drain through a pretreatment
system. Pretre atment systems must conform to
the Uniform Plumbing Code.
When can I anticipate an inspection?
The business will be inspected annually to assure
compliance with permit requirements. The
municipal code authorizes that inspections be
conducted during nor mal business hours and
may be unannounced.
EXHIBIT 7.10F
Doesn’t the county health department already
inspect for compliance with sewer discharge
requirements?
No. The City has primary authority over use of
the sewer system. The county environmental
health ins pector does not inspect sewer
pretreatment systems for proper operation and
maintenance. A county inspector will take
action on a sewer issue if they determine that the
public health is threatened.
What are the penalties for noncompliance?
A Notice of Violation (NOV) is issued if the
noncompliance has likely not resulted in
impairment to the sewer system, such as a
recordkeeping issue. There is no fee or fine with
the first NOV. An administrative citation may
accompany the NOV for likely discharge of FOG
to the sewer and for repeat violations. Follow-up
inspection fees may also apply. There are other
enforcement remedies available for chronic
violations.
Are there fees associated with the permit?
The City of San Mateo has an annual
waste discharge permit fee. For Fiscal Year
2024-25, the fee was $778.00. Foster City/
Estero has adopted a similar fee. The fee
recovers a portion of the cost of the
program. Please submit payment upon
receiving the annual invoice.
How
do I apply for the permit?
The application for a waste discharge permit is
enclosed. Please complete and return
the application
within 10 days of your receipt of
the attached letter (or within 30 days if you have
not yet begun discharging wastewater from
your business). You will have an opportunity
to go over any questions or concerns
with the City/District staff.
Who do I talk to for information and
assistance with this program?
Please contact the City of San Mateo Department
of Public Works, Regulatory Compliance
Division, at (650) 522-7300.

20XX SSMP Triennial Internal Audit
Audit Period: May 2, 20XX to May 2, 20XX
This 20XX SSMP Triennial Internal Audit was prepared for submittal into the online CIWQS Sanitary Sewer System Database per the requirements in section 3.10 of Attachment E1 of State Water Resources Control Board Order WQ 2022-0103-DWQ (“Statewide WDR”). The City’s sewer system operators’ input has been considered in compiling the audit findings below.
This purpose of this audit is as follows:
• Evaluate the implementation and effectiveness of the City’s Sewer System Management Plan in preventing spills;

C. Have the performance trends resulted in modifications or changes to SSMP elements and are the changes identified in the Change Log? C Discussion:
IX.A. The current SSMP includes the assessments described, but does not include them in one section, in Element IX, called Adaptive Management. This information will be consolidated into an Adaptive Management section in the May 2, 2025 SSMP Update. Specifically, Element 10 contains audit findings; prior audits stored in Element 10 have reviewed each plan element for its effectiveness and individual elements have been updated over time in response to these findings. Element 9 has tracked selected performance indicators and provided findings related to these indicators, including summarizing and tracking spill frequency, locations, and estimated volumes.
See the attached charts for updated performance indicators findings for the three-year audit period ending May 2, 2024.
The performance indicators confirm the effectiveness of the City’s Sewer System Management Plan in preventing spills in compliance with the Statewide WDR. Based on the information in this audit as confirmed through performance indicators, there are no deficiencies or modifications recommended in the SSMP, other than the administrative updates that are discussed in this audit.

Element XI – Communications Rating
A.
Does the SSMP include procedures for the City to communicate with the public for:
• Spills and discharges resulting in closures of public areas, or that enter a source of drinking water;
• The development, implementation, and update of the SSMP, including opportunities for public input to Plan implementation and updates; • Coordination with owners/operators of systems that connect into the City’s system, including satellite systems, for system operation, maintenance, and capital improvement-related activities.
SC
Discussion:
XI.A The SSMP discusses the City’s outreach processes and tools for a variety of topics, including spills, community information, and fats, oils, and grease management. The City discusses sewer-related topics, including topics related to SSMP development (up to and including adoption of SSMP updates) at its regularly-scheduled City Council meetings. These meetings are publicly noticed and open to the public.
Although public discussions are held, the SSMP does not include confirmation that the SSMP is discussed at these meetings. Element XI will be updated to include this clarification as part of the May 2, 2025 SSMP Update.

Table 2 shows a decrease in the number of spills in all size categories over the audit period. The only exception to this trend is the number of spills greater than 1,000 gallons in 2023, which were due to wet weather events that have since been resolved through the completion of the City’s Underground Flow Equalization Storage Project (“UFES”) in December 2023. Table 2 confirms the effectiveness of the City’s operations and maintenance program (Element 4) and capacity assurance program (Element 8).
