3. Acronyms and Definitions
Ammonia: A nutrient that contains nitrogen and hydrogen. Its chemical formula is NH 3 in the un-ionized state and NH 4+ in the ionized form. Total ammonia is the sum of both NH3 and NH 4+. Ammonia can be converted to nitrite and nitrate by bacteria. The neutral, un-ionized form (NH3) is highly toxic.
CAM 17: A list of heavy metals in the California Administrative Manual, which includes antimony, arsenic, barium, beryllium, cadmium, chromium, cobalt, copper, lead, mercury, molybdenum, nickel, selenium, silver, thallium, vanadium, and zinc
Corrosive: A substance that causes visible destruction of, or irreversible alteration in, living tissue at the site of contact.
Department: City of Santa Clara Water and Sewer Utilities Dissolved Oxygen : O xygen is measured in its dissolved form as dissolved oxygen (DO). If more oxygen is consumed that is produced, dissolved oxygen levels decline and some sensitive animals may move away, weaken, or die. DO levels vary with water temperature and altitude.

SANITARY SEWER OVERFLOW SAMPLING REV. 001 PAGE 5 OF 20
Employee: Any regular, full -time, part -time or temporary employee employed by the department at any level in the organization, including Managers and Supervisors.
Fecal Coliform: Bacteria found in the intestinal tracts of mammals. Their presence in water or sludge is an indicator of possible contamination by pathogens Managers: All unclassified employees in the department, including the Director of Water and Sewer Utilities, Assistant Director of Water and Sewer Utilities, Water and Sewer Superintendent, Assistant Water and Sewer Superintendent, Compliance Manager, Principal Engineer and any employee in an acting role or out of class assignment as a manager within the Water and Sewer Utilities Department. pH: a measure of the number of hydrogen ions or a solution's acidity. In water, small numbers of water molecules will break apart into hydrogen ions (H+) and hydroxide ions (OH-). Other compounds entering the water may react with these, leaving an imbalance in the numbers of hydrogen and hydroxide ions. When more hydrogen ions react, more hydroxide ions are left in solution and the water is basic; when more hydroxide ions react, more hydrogen ions are left and the water is acidic.
POTW: Publicly Owned Treatment Works
Sampling Apparatus: Device used to obtain sample directly from surface water discharge site and transfer to appropriate containers.
Sanitary Sewer Overflow (SSO) : A condition whereby untreated sewage is discharged into the environment prior to reaching the wastewater treatment plant.
Qualifying SSO : For purposes of this procedure a qualifying SSO shall mean any Sanitary Sewer Overflow greater than or equal to 50 gallons which reaches surface waters.
4. Responsibilities
4.1. Sanitary Sewer Operations & Maintenance Employees

Ecotoxicity: No data available. No information available.
Environmental: Terrestial: During transport through the soil, nitric acid will dissolve some of the soil material, in particular, the carbonate based materials. The acid will be neutralized to some degree with adsorption of the proton also occurring on clay materials. However, significant amounts of acid are expected to remain for transport down toward the ground water table. Upon reaching the ground water table, the acid will continue to move, now in the direction of the ground water flow.

Grease Management
Grease Interceptor
Maintenance
What is the Purpose of
a Grease Interceptor?
• A grease interceptor is designed
to separate Fats, Oils, and Grease
(FOG) and solid food waste from
your kitchen wastewater.
• Buildup of FOG and solid
food waste in your plumbing
may cause blockages in either
your plumbing or the sanitary
sewer lines. This can lead to a
sanitary sewer overflow into your
building, a neighbor’s building,
streets, or the environment. It is
important to clean your grease
interceptor regularly .
Cleaning Frequency
• Grease interceptors shall be
cleaned at least once every
90 days. More frequent cleaning
may be necessary to keep your
interceptor operating properly .
Twenty-Five Percent Rule
• Pump your interceptor when
the final chamber is twenty-
five percent (25%) full of FOG
and solid food waste or within
90 days of the last pumping,
whichever comes first
.
Grease in the system causes problems in storm drains and sanitary sewers — and increases your operating costs.
Standards for Evaluating
Grease Interceptors
• Manhole and sample box lids
should be easily r emovable
for cleaning and inspections.
• The baffle wall and all three
standpipes must be in place
and u nbroken , above and below
the water and grease levels.
• If any standpipes are under
water or grease, they must be
raised above the grease level.
High water or grease level
could result from a blockage
in the downstream pipes.
• Downstream blockages could
indicate inadequate interceptor
cleaning frequency .
Grease
Interceptor
Kitchen Best Management Practices (BMPs)
• Grease and solid food waste can build up inside the i nterceptor a nd m ay cause the interceptor to operate less efficiently .
• Scraping grease and food waste to the garbage before wa shing di shes will minimize the amount of grease and solid s going into the grease interceptor and will improve interceptor performance.
Tips on Routine Grease Interceptor Maintenance
• The pumping service should wash and scrape all sides, standpipes, and surfaces inside the interceptor and completely pump out all contents. • The pumping service shall not decant (return) wastewater back into the interceptor; the grease concentration in interceptor wastewater is very hi gh. • Make sure your pumping service cleans the sample box and effluent standpipe of the interceptor. You may need to pump more often if you see fresh grease being discharged into your sample box.
• Require the pumping service to show the disposal destination for your waste on the pumping invoice. Your business may be liable for any illegal dumping or discharge of waste from your facility .
• Do visual inspections after pumping services are performed or when plumbers snake or hydro-jet plumbing or laterals to make sure the interceptor standpipes are not damaged.
• Keep grease interceptor pumping records on site for a minimum of three years. Refer to the Grease Control Device Maintenance Recordkeeping sheet for more information.
Failure to maintain records on site for a minimum of three years is a violation of your local sewer ordinance and may result in fines. See the “Grease Control Device Maintenance Recordkeeping” factsheet for more information.

may cause blockages in either
your plumbing or the sanitary

to clean your grease trap regularly .
Cleaning Frequency
• Grease traps shall be cleaned at
least once every 30 days. More
frequent cleaning may be
necessary if:
• Your sinks are draining slowly,
possibly due to buildups in the trap.
• Water levels in the trap or floor drains
are high, possibly due to grease-related
blockages in your plumbing.
• The grease trap smells bad because
solids are filling the bottom of the
trap q uickly.
• Y our trap is not sized correctly for
your restaurant operations, menu,
or number of meals served.
Twenty-Five Percent Rule
• Clean the trap when it is twenty-
five percent (25%) full of FOG
and solid food waste or within
30 days of the last pumping,
whichever comes first

Common Problems
Leading to Grease Trap
Repair or Replacement
• Grease trap installed
backwards, without flow
controls, or otherwise in
violation of plumbing codes or
manufacturer s pecifications.
• Missing or damaged parts,
such as the removable
baffle plates.
• Leaks due to rust holes or
punctures in the walls or floors.
• Illegal c onnection to the
dishwasher o r ga rbage g rinder
to the grease trap.
Grease Trap
Kitchen Best Management Practices (BMPs)
• Scraping grease and food waste to the garbage before washing dishes will minimize the amount of grease and solids going into the grease trap and will often improve trap performance.
Tips on Routine Grease Trap Maintenance
• To ensure proper maintenance, we recommend using a professional grease hauling company .
• Cleaning consists of emptying the entire trap, including FOG, wastewater, and solid food waste; making sure the removable baffle plates and parts are thoroughly cleaned and replaced properly after each cleaning.
• Keep a m aintenance l og s heet p osted n ear t he g rease t rap i f y ou self-clean the trap.
• Melt ice in the sink plumbed to the grease trap an hour or two before cleaning. This helps cool and harden the grease in the trap, making cleaning easier and reducing odors.
• Have an extra gasket available for your grease trap lid and use allen screws (which resist stripping) to secure the lid.
• Run your hood fans during cleaning to reduce odors.
• Call a plumber to snake or hydro-flush your sewer lateral (plumbing) pipes to the street periodically to remove any blockages. • If you choose to self-clean your grease trap, please see the "How to Clean Your Grease Trap" poster for guidance.

Hello,
I am a Code Enforcement Technician with the City of Santa Clara. I am here to perform an inspection of your business. Santa Clara conducts inspections of restaurants, cafetereias, and other food service operations. We inspect these businesses to ensure that they are:
1. In compliance with environmental laws, and
2. Not releasing excessive grease into the sanitary sewer that can cause sanitary sewer blockages, backups, and overflows.
The inspection will consist of asking you questions about your business activities, walking through your business site, and reviewing certain records. We will also provide you with educational materials and information that can help your business stay in compliance with water pollution laws and protect the environment.
We appreciate the opportunity to work with you to protect the sanitary sewer system and minimize pollution of our local creeks, rivers, and the Bay. For additional information on this inspection and ways you can help us protect our local waterways, please visit our website www.santaclaraca.gov or call our office at 408.615.2000
Grease Management
Prohibitions on using
Chemicals, Enzymes, or Bacteria
in Grease T raps and Interceptors
Grease in the system causes problems in storm drains and sanitary sewers — and increases your operating costs.
Chemicals: the use
of chemicals to
clean grease traps
or interceptors is
strictly prohibited
because:
• Local sewer use ordinances
prohibit the use of chemicals as
a method to remove grease from
your grease trap or interceptor.
• Cleaners, solvents, caustics,
or other chemicals cannot be
used to dissolve accumulated
grease from your grease trap
or grease interceptor. These
chemicals cause grease to flow
out of your trap or interceptor
in violation of local ordinances.
The grease may deposit on
sewer pipes downstream of your
business, obstructing them and
contributing to sewer overflows.
Enzymes: the use
of enzymes to
clean grease traps
or interceptors is
strictly prohibited
because:
• Whether produced synthetically
or from animals, enzymes cannot
be used to dissolve grease from
your grease trap or interceptor.
• Enzymes can temporarily
alter the chemical form of the
grease, allowing it to dissolve
into the water. However, the
altered grease may reform into
solid matter downstream from
your business, obstructing
sewer pipes.
Bacteria: the use
of bacteria to
clean grease traps
or interceptors is
strictly prohibited
because:
• Bacteria need a reliable
environment to grow and
are sensitive to changes in
temperature, pH, oil and
grease loading, water flow
changes, etc. It is difficult
to maintain the conditions
necessary for bacteria to thrive
in a kitchen environment.
Biological expertise and ongoing
sampling are often needed for
bacteria to be sustainable.
• Even if bacteria survive and
flourish, their effectiveness in
removing grease is limited.
“Partially eaten” (i.e., not broken
down completely) grease may
still enter the plumbing and over
time reform into solid matter
downstream, obstructing the
sewer pipes.

Per the sewer use ordinance:
“ No person shall
discharge…any
substance of any kind
whatsoever tending
to obstruct or injure
the sanitary sewer
system, or to cause a
nuisance or hazard,
or which will in any
manner interfere with
the proper operation or
maintenance of the
sanitary sewer system.”
In general…
• Greasy wastewater may not be discharged to the sanitary sewer system unless it has been treated using a grease trap or interceptor approved by the Environmental Services Department.
• Floating or solid grease matter must be physically removed from your grease removal device by pumping, scraping, scooping, etc. • Maintain your grease trap and interceptor in efficient operating condition by regular removal of accumulated grease.
• The minimum cleaning frequency required for grease interceptors installed in food service facilities is once every 90 days. However, more frequent cleaning may be necessary.
• The minimum cleaning frequency required for grease traps installed in food service facilities is once every 30 days. However, more frequent cleaning may be necessary.
Grease Management
Proper Cleaning and Rinse
Water Disposal for Exhaust Hoods,
Filters, Ducting, Roof Fans, and Floor Mats
Cleaning Exhaust Hoods
and Exhaust Hood Filters
On Site
• Dr y-wipe and scrape grease off of
all surfaces before washing.
• Empty and clean the grease
co
llection trays located inside of
the exhaust hoods regularly.
Cleaning Exhaust
Hood Filters Off Site
• T he business owner may choose
to use professional services to
ex
change dirty exhaust hood
filters for clean ones.
Cleaning Frequency
• C heck your lease agreements and
fire insurance policies to determine
the minimum frequency that you
must clean your equipment.
• More frequent cleaning may be
necessary if grease collects quickly.
Grease in the system causes problems in storm drains and sanitary sewers — and increases your operating costs.
Cleaning Exhaust
Ducting and Rooftop
Exhaust Fans
• Do not allow wash and rinse
water to go into downspouts.
• Do not leave pooled wash and
rinse water on the roof.
• Collect the wash and rinse
water and discharge to the
sanitary sewer drains inside
your business.
Whether you contract with
a professional service,
perform the cleaning yourself,
or do both, you are liable
for any illegal disposal
of waste or rinse water
resulting from cleaning
your exhaust hood, filters,
ducting, and roof fans. This
includes any cleaning that
occurs off site.
Never clean exhaust hoods
or filters outdoors where
wash water may flow to a
storm drain.
Proper Disposal of Filter Bath Solution
• Used bath solution from soaking exhaust hood filters (both hazardous and non-hazardous) should be taken to an off-site disposal facility. You and your property manager are liable for any illegal disposal of your waste.
Proper Disposal of Water from Equipment Cleaning
• Do not dispose of the concentrated solution, wash water, or rinse water f
rom cleaning or degreasing equipment or exhaust hood surfaces into s
inks leading to a grease trap or mechanical grease removal device. • Do dispose of the concentrated solution, wash water, or rinse water into a mop-sink, sink, or floor drain connected directly to the sani
tary sewer system.
• Do dispose of wastewater from steam cleaning without chemicals to a gre
ase trap or mechanical grease removal device.
• Do not pour concentrated chemicals into sinks, mop sinks, or floor drains plumbed to grease control devices. This may cause liquefied grease to escape the grease control device and could cause a bloc
kage in your drainage system.
Proper Disposal of Water from Cleaning Floor Mats
Wash water from cleaning floor mats must never flow out the back door, onto the parking lots, into a gutter, or into a storm drain. Clean mats:
• In a mop sink or near a floor drain, or
• Outside in a designated area that flows to a sanitary sewer drain, or • In a garbage can; then dispose of the wash water into a mop sink.
Discharging anything,
including oil, grease
waste, wash water, or
rinse water to the
storm drain system
is a violation of the local
sewer
use ordinance.
