I. The director may develop best management practices (BMPs) in individual wastewater
discharge permits, to implement local limits and the requirements of this chapter.
J. The contents of swimming pools and/or spas (including filter backwash from swimming
pools and/or spas) shall only be discharged into the sanitary sewer in the manner specified
herein.
1. The water is discharged by pumping and shall not exceed the capacity of the
sewer lateral and/or public main.
2. Each swimming pool discharging to a sewer system shall be equipped with an
indirect waste connection to preclude any possibility of a backflow of sewage into the
swimming pool or piping system.
3. Draining, pools, reservoirs, or tanks with a capacity of five hundred thousand
gallons or greater require an approved drainage schedule. This drainage schedule shall
be submitted to and approved by the director or designee at least fourteen days prior to
starting drainage, to reduce the likelihood of a sanitary sewer overflow or POTW upset.
(Ord. 1734 § 8, 2024; Ord. 1598 § 1, 2014)
Industrial users must comply with the categorical pretreatment standards found at 40 CFR

Article III. Pretreatment of Wastewater
Users shall provide wastewater treatment as necessary to comply with this chapter and
shall achieve compliance with all categorical pretreatment standards, local limits, and the
prohibitions set out in Section 13.08.040 within the time limitations specified by EPA, the
state, or the director, whichever is more stringent. Any facilities necessary for compliance
shall be provided, operated, and maintained at the user’s expense. Detailed plans
describing such facilities and operating procedures shall be submitted to the director for
review, and shall be acceptable to the director before such facilities are constructed. 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 city under the provisions of this chapter. All pretreatment facilities must comply with all
other applicable laws. (Ord. 1598 § 1, 2014)
A. Sanitary sewer overflows (SSOs) are a major concern to wastewater agencies
throughout the state of California. The Statewide General Waste Discharge Requirements
for Sanitary Sewer Systems requires the city to have a FOG discharge control program. A
frequent cause of SSOs is the blockage of sewer lines due to discharge of fats, oils, and
grease (FOG) into the sanitary sewer systems from food preparation and clean-up
operations. To prevent SSOs in its sanitary sewer system, the city of San Luis Obispo has
developed and implemented a program, as set forth herein, to reduce the discharge of FOG
from restaurants and other food service establishments (FSEs) to mitigate blockages in
sewer lines. This program enables the city of San Luis Obispo to comply with requirements
of the California State Water Resources Control Board.
B. This program helps to protect public health and safety through:
1. Reducing the potential for blockages of and sewage releases from the city’s sewer
systems due to accumulation of fats, oils, or grease;
2. Reducing the city’s costs of operating the sewer system;
3. Promoting proper handling and disposal of fats, oils, and grease through
educational and regulatory programs.
C. Upon adoption of the ordinance codified in this chapter, all food service establishments
(FSEs) shall be subject to this chapter to the extent permitted by law. Any facility with a
permanently plumbed connection to the city sewer system that has the potential to generate
discharges of fats, oils, or grease (FOG) must comply with this chapter.
D. Except as otherwise provided herein, the director shall administer, implement, and
enforce the provisions of this chapter. Any powers granted to or duties imposed upon the
director may be delegated by the director to a duly authorized city of San Luis Obispo
employee. (Ord. 1734 § 8, 2024; Ord. 1598 § 1, 2014)

Page 17 of 53
A. Permit Required. All new FSEs and all existing FSEs shall have a current Class II
industrial user permit issued by the director and at least one grease control device (GCD).
B. Permit Fees. Section 13.08.140 specifies that the city shall have the authority to assess
and collect fees from users of the sanitary sewer system to recover costs incurred by the
city when regulating discharges into the system. The fees specified therein are applicable to
all FSEs. For a current cost of the annual permit fee, refer to the current city fee schedule.
C. Re-Inspection Fee. If an inspection by city staff determines that a permittee is in
violation of one or more requirements of this chapter, the permittee shall be charged a re-
inspection fee to reimburse the city for the cost of a re-inspection to determine that the
violation has been corrected. Additional fees may be assessed if an administrative citation is
issued to the permittee, as discussed in Chapter 1.24.
D. Used Cooking Oil Container. All FSEs shall have a container or drum for collecting
waste kitchen grease and used cooking oil unless deemed unnecessary by the director.
FOG removed from GCDs shall not be placed in this container, as it is more difficult to
recycle. The container shall be used and maintained appropriately so as to prevent spills or
leaking. The container shall be serviced (emptied or exchanged) and recycled by a waste
hauler at an appropriate frequency as defined by Section 13.08.093 (Maintenance and
operation of grease control devices). Receipts or other documentation of such service shall
be retained at the FSE and presented to the city on request. The FSE shall maintain
adequate employee training and/or signage to assure that the container is used and
maintained in an appropriate manner, as discussed in subsection G of this section, Kitchen
Best Management Practices. Any oil on or around collection container or drum shall be
cleaned up immediately. Failure to maintain this area may constitute a violation of Section
13.08.096.
E. Stormwater Pollution. All FSEs shall operate in a manner which prevents any discharge
of FOG or other wastes to the stormwater drain system. Any outdoor spills or washing
activities may constitute a violation of Chapter 12.08.
F. Inspections.
1. To the extent permitted by law, city representatives may enter upon a facility’s
premises to determine compliance with this chapter. The city shall attempt to perform
inspections in a manner so as to minimize the impact on the operation of the food
service establishment. However, the FSE shall provide the city, at all times that the FSE
is open to the public and/or in operation, with access to the premises, specifically the
GCDs, used cooking oil containers and maintenance records. If the GCD or used
cooking oil container is inaccessible to city representatives due to placement of
vehicles, mats, utensils, etc., FSE staff shall immediately remove such obstacles upon
city entry for inspection.
2. Inspections may occur during normal operating hours without warning to verify
appropriate grease control device maintenance and operation as well as during an
emergency response or blockage investigation. Inspections will include all parts of the
FSE that discharge or have the potential to discharge to the sanitary sewer system.
City representatives will comply with all reasonable facility safety requirements as
provided by the FSE operator at the time of entry.
3. Below is an outline of the city’s routine inspection and enforcement procedures.
a. Inspect the GCD by assessing the amount of grease and solids as a
percentage of the total volume;
13.08.091
Food service establishment requirements.
https://sanluisobispo.municipal.codes/Code/13.08.020 17/53
Page 18 of 53
b. Inspect the structural integrity of the GCD;
c. Assess whether the GCD maintenance frequency is sufficient as defined by
Section 13.08.093 (Maintenance and operation of grease control devices);
d. Inspect that all floor drains have strainer baskets not to exceed 3/16-inches in
hole diameter;
e. Ensure that all kitchen best management practices are being implemented as
set forth in subsection G of this section to minimize FOG from entering the sewer;
and
f. Inspect recycled oil storage and trash areas for cleanliness and compliance
with applicable stormwater codes (Chapter 12.08).
G. Kitchen Best Management Practices. The following best management practices
(BMPs) must be followed by all FSEs:
1. Always dry wipe all pots, pans, and cooking equipment to remove leftover fat, oil,
grease, and food waste prior to pre-rinsing or washing.
2. Install and maintain screens in all floor and sink drains. The floor drain screens
must be a basket style and have a hole diameter of 3/16-inches or smaller. Dome style
strainers are prohibited. The sink drains must be a fine mesh style, where applicable, or
a similar type approved by the director.
3. Maintain grease control device(s) (GCD) to comply with the following:
a. In accordance with the manufacturer ’s instructions when the grease storage
capacity of the GCD can be validated to exceed twenty-five percent of the total
liquid volume by third-party performance testing; or
b. If the grease storage capacity of the GCD cannot be validated by third-party
performance testing, the total depth of the floating FOG layer, plus the settled
sludge layer cannot exceed twenty-five percent or more of the total liquid depth of
the GCD.
4. Regularly maintain vent hood and filters and dispose of the waste to a drainage
fixture connected to a GCD.
5. Wash all floor mats, grills, and greasy kitchen equipment in a drainage fixture
connected to a GCD. Never wash equipment outside.
6. Place source-separated food and green waste in the organic material container
pursuant to Section 8.04.213.
7. Display the FOG poster for all employees to see, ideally in the kitchen or
dishwashing area.
8. Place “No Grease” stickers in dishwashing areas. Stickers are provided by the city
at no charge and are available in English and Spanish.
H. Staff Training Requirements.
1. An annual training on kitchen BMPs as stated in subsection G of this section must
be completed and documented for all staff. Records of this training must be kept on site
for a minimum of three years and must be made available to city staff upon request
during an inspection.
2. The training record must include the following:
a. What was covered during the training.
b. A list of names and signatures of all who attended the training.
https://sanluisobispo.municipal.codes/Code/13.08.020 18/53
Page 19 of 53
I. Any FSE undergoing a kitchen remodel, as defined in Section 13.08.020, shall be
required to submit GCD plans to the city for review.
J. Any FSE or other facilities identified under Section 13.08.090(C) must notify the city
within thirty days, and may be required to install a grease control device, when any of the
following changes occur or are planned:
1. Facility or operational modifications;
2. Changes to the type of food service;
3. Change of operator of the facility; or
4. Installation of a new GCD or transfer of responsibility for a GCD. (Ord. 1734 § 8,
2024)
A. GCDs must be sized according to both of the following steps:
1. Calculate Flow Rate. The minimum flow rate for a GCD may be calculated by
either fixture volume or pipe diameter, as stated in the CPC, using either a one-minute
or two-minute drainage period. Use a one-minute drainage period when the GCD will
be installed within twenty feet of directly connected fixtures and/or has indirectly
connected fixtures. When the interceptor will be installed beyond twenty feet of the
connected fixtures, use a two-minute drainage period.
Note: per subsection J of this section, each GCD shall receive the drainage from all
plumbing fixtures, equipment, and drain lines located in the food preparation, food
service, alcohol service, and clean-up areas of FSEs, including but not limited to multi-
compartment sinks, utensil sinks, food preparation sinks, pre-rinse sinks, dishwashers,
hand washing sinks, floor sinks, floor drains, trench drains, and mop sinks.
2. Calculate Grease Capacity. Once the minimum flow rate has been established in
step one, calculate the minimum grease storage capacity for the GCD required for the
desired cleaning frequency, noting that required cleaning cannot be more frequent than
ninety days. Use the following formula to correctly calculate the grease capacity
required.
To determine the appropriate grease factor, using Table 13.08.092.A, select the menu
type (1 through 33), then the correct column (A through D) for whether there is a fryer,
and whether the establishment uses disposable or washable plates, glasses, knives,
forks, and spoons (flatware). The table was produced from guidance in the American
Society of Plumbing Engineers (ASPE) Plumbing Engineering Design Handbook 4,
Plumbing Components and Equipment, Chapter 8, Grease Interceptors.

B. The approved GCD will meet the minimum flow rate from step one and the minimum
grease capacity from step two above. In order to meet the minimum grease capacity in step
two, a GCD with a higher flow rate may be required than is determined in step one.
C. Prior to installing or replacing a GCD as may be required by this chapter, FSEs must
complete the city’s GCD sizing and selection worksheet with all required information and
submit to the community development department for review and approval. Incomplete
worksheets submitted will not be accepted and could delay project approval.
D. All FSEs installing or replacing a GCD pursuant to this chapter must submit a building
permit application and the following documents to the community development department:
1. Map/drawing of all plumbing fixtures that will discharge to the proposed GCD.
2. Calculations for sizing of proposed GCD on the city’s GCD sizing and selection
worksheet.
3. Manufacturer ’s specification sheet of proposed GCD. (See subsection E of this
section for prohibited materials and conditions of approval.)
E. The following CGDs are prohibited unless otherwise approved by the director:
1. Gravity grease interceptors.
2. Grease removal devices built from concrete.
3. GCDs built from metal, including metal GCDs with acid-resistant enamel or epoxy
coatings.
https://sanluisobispo.municipal.codes/Code/13.08.020 20/53
Page 21 of 53
F. Any facility identified as needing to install or replace a GCD must do so in accordance
with this chapter within one hundred eighty days of notification from the city, unless
approved otherwise by the director.
G. Hydromechanical grease interceptors (HGIs) shall meet the following minimum
requirements:
1. Be constructed of a corrosion-resistant polymer.
2. No injection ports for chemicals or bacteria.
3. Installed per manufacturer ’s specifications.
4. Appropriate flow restrictors, whether integral or external to the device, must be
installed.
5. Shall meet the specifications and be constructed in accordance with the applicable
provisions of the California Plumbing Code.
6. Shall be third-party tested and rated for efficiency and capacity in accordance with
ASME A112.14.3, CSA B481, or PDI G101.
H. Each GCD shall be installed and connected at an exterior location such that it is at all
times easily accessible for visual inspection, sampling, cleaning and removal of grease and
other matter from all surfaces. The location of the GCD must be approved by the county,
and shall not be located in a food or utensil handling area unless specifically approved by
the county. The GCD must be installed prior to final city permit inspections.
I. A GCD shall be situated outdoors on the FSE’s premises, except when such a location
would be impractical or cause undue hardship on the FSE. The city may issue an
encroachment permit to allow the GCD to be installed in the public street or sidewalk area
and located so that it will not be obstructed by landscaping or parked vehicles. If the GCD
cannot be located outdoors pursuant to the terms of this provision, and the city does not
issue an encroachment permit, then the FSE may install a GCD at an approved interior
location that meets the requirements of applicable plumbing codes and this chapter at the
discretion of the director.
J. Each GCD shall receive the drainage from all plumbing fixtures, equipment, and drain
lines located in the food preparation, food service, alcohol service, and clean-up areas of
FSEs, including but not limited to multi-compartment sinks, utensil sinks, food preparation
sinks, pre-rinse sinks, dishwashers, hand-washing sinks, floor sinks, floor drains, trench
drains, and mop sinks.
K. All FSEs shall ensure that wastes collected by GCDs are disposed of at a facility
permitted to receive such wastes. FOG wastes must not be allowed to discharge to any
private or public portion of the sanitary or stormwater collection systems.
L. The use of additives, emulsifiers, enzymes, or biological agents to break down or digest
FOG for discharge to the sewer system is prohibited, unless authorized by the director.
M. Food waste disposers are prohibited.
N. Any waste material from routine cleaning of exhaust hoods, ducts, floor mats, and mop
water shall be plumbed to the GCD prior to discharge to the sanitary sewer.
O. No drains from toilets, showers, or other domestic discharges shall be connected to the
GCD. (Ord. 1734 § 8, 2024)
https://sanluisobispo.municipal.codes/Code/13.08.020 21/53
Page 22 of 53
A. GCDs shall be maintained in efficient operating condition by periodic removal of the
accumulated grease. No accumulated grease shall be introduced into any drainage piping
or public or private sewer. The total depth of FOG layer shall not exceed the maximum rated
capacity as established by the manufacturer of the GCD. If this information is not available,
then the FOG layer plus the settled sludge layer cannot exceed twenty-five percent or more
of the total liquid depth of the GCD.
B. GCDs shall be cleaned on a sufficient frequency to prevent objectionable odors,
surcharge of the GCD, or interference with the operation of the sanitary sewer system. The
required minimum frequency for maintaining the GCDs shall be determined during a routine
inspection. A re-inspection may be requested to re-evaluate the required cleaning
frequency. In the absence of a frequency determined and set by the city, the following is the
required minimum frequency of cleaning for each type of GCD, unless otherwise approved
by the director:
1. HGIs shall be cleaned at least once every thirty days.
2. Nonconforming existing GGIs shall be cleaned at least once every ninety days.
C. If a GCD is properly sized and installed, yet requires cleaning and maintenance at a
greater frequency than the frequency determined in accordance with this section, then the
director can require a GCD with a higher flow rate and grease capacity to be installed.
D. GCDs shall be cleaned by being pumped dry and all accumulated sludge on all
surfaces shall be removed by washing down the sides, baffles, tees, and any other interior
components. No water removed from the device during cleaning shall be returned to the
GCD.
E. The director may grant an exception to the requirements of subsections (B)(1) and (B)
(2) of this section where the director finds, based on evidence presented by the FSE, that a
less frequent cleaning schedule will be sufficient to assure that the GCD will continue to
operate efficiently and will not bypass FOG to the sanitary sewer system. The director may
require more frequent cleaning if inspections indicate that cleaning at the current frequency
is not adequate. Documentation provided by the FSE shall be based on a minimum of one
year of cleaning and shall be verified by city inspections.
1. Waste Hauler Requirements. All GCD cleaning shall be performed by waste
haulers who are certified by the California Department of Food and Agriculture (DFA) as
an “inedible kitchen grease commercial transporter.” The pumper shall transport the
pumped waste to an “authorized receiving facility,” as defined by the DFA.
F. Persons cleaning a GCD shall ensure that all grease and sediment is removed and
appropriately disposed. They shall also ensure that all baffles, flow control devices, and
other equipment are properly installed subsequent to the cleaning. All wastes removed from
the GCD during cleaning shall be placed in a dedicated container and be removed by an
“inedible kitchen grease commercial transporter,” as described above. The waste may not
be placed in the used cooking oil container, unless the grease hauler provides written
certification that this is acceptable, and the hauler complies with all DFA regulations for
“inedible kitchen grease.”
G. FSEs may not clean GCDs themselves, unless specific approval is granted by the
director.
H. All FSEs shall implement best management practices (BMPs) in their operations to
minimize the discharge of grease to the sanitary sewer system. See Section 13.08.091(G).

(Ord. 1734 § 8, 2024; Ord. 1598 § 1, 2014)
Article VI. Reporting Requirements
A. Any discharger of nondomestic wastewater may be required to submit to the director a
report indicating the nature, concentration and daily flows of all limiting pollutants. The
report shall also state whether the applicable pretreatment standards and requirements are
being consistently met.
B. After meeting the requirements set forth in subsection A of this section, the user shall
submit self-monitoring reports, as required by the director, to assess and assure continued
compliance with pretreatment standards and requirements, including, but not limited to, the
reports required in 40 CFR 403.12. These reports shall contain the results of sampling and
analysis of the discharge, done in accordance with the procedures approved by the POTW.
C. Reports, such as but not limited to those identified in subsections A and B of this
section, shall be signed and certified by an authorized representative of the discharging
facility.
D. All industrial users shall be required to retain for a minimum of three years any records
and/or reports of monitoring activities or results and shall make such records/reports
available for inspection and copying by the POTW. This period of retention shall be
extended during the course of any pending litigation regarding the industrial user.
E. Notification of the Discharge of Hazardous Waste.
1. Any user who commences the discharge of hazardous waste shall notify the
POTW, the EPA Regional Waste Management Division Director, and state hazardous
waste authorities, in writing, of any discharge into the POTW of a substance which, if
otherwise disposed of, would be a hazardous waste under 40 CFR Part 261. Such
notification must include the name of the hazardous waste as set forth in 40 CFR Part
261, the EPA hazardous waste number, and the type of discharge (continuous, batch,
or other). If the user discharges more than one hundred kilograms of such waste per
calendar month to the POTW, the notification also shall contain the following
information to the extent such information is known and readily available to the user: an
identification of the hazardous constituents contained in the wastes, an estimation of
the mass and concentration of such constituents in the wastestream discharged during
that calendar month, and an estimation of the mass of constituents in the wastestream
expected to be discharged during the following twelve months. All notifications must
take place no later than one hundred eighty days after the discharge commences. Any
notification under this subsection need be submitted only once for each hazardous
waste discharged. However, notifications of changed conditions must be submitted
13.08.160
Reporting requirements for permittees.
https://sanluisobispo.municipal.codes/Code/13.08.020 29/53
Page 30 of 53
under this article. The notification requirement in this section does not apply to
pollutants already reported by users subject to categorical pretreatment standards
under the self-monitoring requirements of this article.
2. Dischargers are exempt from the requirements of subsection A of this section
during a calendar month in which they discharge no more than fifteen kilograms of
hazardous wastes, unless the wastes are acute hazardous wastes as specified in 40
CFR 261.30(d) and 261.33(e). Discharge of more than fifteen kilograms of nonacute
hazardous wastes in a calendar month, or of any quantity of acute hazardous wastes
as specified in 40 CFR 261.30(d) and 261.33(e), requires a one-time notification.
Subsequent months during which the user discharges more than such quantities of any
hazardous waste do not require additional notification.
3. In the case of any new regulations under Section 3001 of RCRA identifying
additional characteristics of hazardous waste or listing any additional substance as a
hazardous waste, the user must notify the director, the EPA Regional Waste
Management Waste Division Director, and state hazardous waste authorities of the
discharge of such substance within ninety days of the effective date of such
regulations.
4. In the case of any notification made under this section, the user shall certify that it
has a program in place to reduce the volume and toxicity of hazardous wastes
generated to the degree it has determined to be economically practical by the director.
5. This provision does not create a right to discharge any substance not otherwise
permitted to be discharged by this chapter, a permit issued thereunder, or any
applicable federal or state law. (Ord. 1734 § 8, 2024; Ord. 1598 § 1, 2014)
A. Within either one hundred eighty days after the effective date of a categorical
pretreatment standard, or the final administrative decision on a category determination
under 40 CFR 403.6(a)(4), whichever is later, existing categorical industrial users currently
discharging to, or scheduled to discharge to, the POTW shall submit to the director a report
containing the information listed in subsection C of this section.
B. At least ninety days prior to commencement of their discharge, new sources, and
sources that become categorical industrial users subsequent to the promulgation of an
applicable categorical standard, shall submit to the director a report containing the
information listed in subsection C of this section. A new source shall report the method of
pretreatment it intends to use to meet applicable categorical standards. A new source shall
also give estimates of its anticipated flow and quantity of pollutants to be discharged.
C. IUs described above shall submit the information set forth below:
1. Identifying Information. The IU shall submit the name and address of the facility,
including the name of the operator and owners.
2. Permits. The IU shall submit a list of any environmental control permits held by or
for the facility.
3. Description of Operations. The IU shall submit a brief description of the nature,
average rate of production, and standard industrial classification of the operation(s)
carried out by such IU. This description shall include a schematic process diagram that

Page 31 of 53
4. Flow Measurement. The IU shall submit information showing the measured
average daily and maximum daily flow, in gallons per day, to the POTW from each of
the following:
a. Regulated process streams; and
b. Other streams as necessary to allow use of the combined waste stream
formula of 40 CFR 403.6(e). The city may allow for verifiable estimates of these
flows where justified by cost or feasibility considerations.
5. Measurement of Pollutants.
a. The IU shall identify the pretreatment standards applicable to each regulated
process; and
b. The IU shall submit the results of sampling and analysis identifying the nature
and concentration of regulated pollutants in the discharge from each regulated
process. Both daily maximum limit and daily discharge concentrations shall be
reported. The sample shall be representative of daily operations.
c. A minimum of four grab samples must be used for pH, cyanide, total phenols,
oil and grease, sulfide, and volatile organics. For all other pollutants, twenty-four-
hour composite samples must be obtained through flow-proportional composite
sampling techniques where feasible. The city may waive flow-proportional
composite sampling for any IU that demonstrates that flow-proportional sampling is
infeasible. In such cases, samples may be obtained through time-proportional
composite sampling techniques or through a minimum of four grab samples where
the IU demonstrates that this will provide a representative sample of the effluent
being discharged.
d. The IU shall take a minimum of one representative sample to compile the data
necessary to comply with the requirements of this section.
e. Samples should be taken immediately downstream from pretreatment facilities
if such exist or immediately downstream from the regulated process if no
pretreatment facility exists. If other wastewaters are mixed with the regulated
wastewater prior to pretreatment, the IU shall measure the flows and
concentrations necessary to allow use of the combined waste stream formula of 40
CFR 403.6(e) in order to evaluate compliance with the pretreatment standards.
Where an alternate concentration has been calculated in accordance with 40 CFR
403.6(e) this adjusted limit along with supporting data shall be submitted to the city.
f. Sampling and analysis shall be performed in accordance with the techniques
prescribed in 40 CFR Part 136 and amendments thereto. Where 40 CFR Part 136
does not contain sampling or analytical techniques for the pollutant in question, or
where the director determines that the 40 CFR Part 136 sampling and analytical
techniques are inappropriate for the pollutant in question, sampling and analyses
shall be performed by using validated analytical methods or any other applicable
sampling and analytical procedures, including procedures suggested by the city or
other parties, and approved by the director.
g. The city may allow the submission of a baseline report that utilizes only
historical data so long as the data provides information sufficient to determine the
need for industrial pretreatment measures.
h. The baseline report shall indicate the time, date, and place of sampling, and
methods of analysis, and shall certify that such sampling and analysis is
representative of normal work cycles and expected pollutant discharges to the
POTW.
https://sanluisobispo.municipal.codes/Code/13.08.020 31/53

6. Compliance Certification. The IU shall submit a statement, reviewed by an
authorized representative of the IU (as defined in Section 13.08.160 and certified to by
a qualified professional) indicating whether pretreatment standards are being met on a
consistent basis, and, if not, whether additional operation and maintenance (O&M)
and/or additional pretreatment is required for the IU to meet the pretreatment standards
and requirements.
7. Compliance Schedule. If additional pretreatment and/or O&M will be required to
meet the pretreatment standards, the IU shall submit the shortest schedule by which
the IU will provide such additional pretreatment and/or O&M. The completion date in
this schedule shall not be later than the compliance date established for the applicable
pretreatment standard. A compliance schedule shall meet the requirements set forth in
Section 13.08.180.
8. All baseline monitoring reports must be certified in accordance with this section
and be signed by an authorized representative of the discharging facility. (Ord. 1734 § 8,
2024; Ord. 1598 § 1, 2014)
A. The schedule shall contain progress increments in the form of dates for the
commencement and completion of major events leading to the construction and operation of
additional pretreatment required for the IU to meet the applicable pretreatment standards
(such events include, but are not limited to, hiring an engineer, completing preliminary and
final plans, executing contracts for major components, commencing and completing
construction, and beginning and conducting routine operation).
B. No increment referred to above shall exceed nine months.
C. The IU shall submit a progress report to the director no later than fourteen days
following each date in the schedule and the final date of compliance, including in such
progress report, at a minimum, whether it complied with the increment of progress, the
reason for any delay, and if appropriate, the steps taken by the IU to return to the
established schedule. In no event shall more than nine months elapse between submissions
of such progress reports to the director. (Ord. 1734 § 8, 2024; Ord. 1598 § 1, 2014)
Within ninety days following the date for final compliance with applicable categorical
pretreatment standards, or in the case of a new source, following commencement of the
introduction of wastewater into the POTW, any user subject to such pretreatment standards
and requirements shall submit to the director a report containing the information described
in 40 CFR 403.12(d). (Ord. 1598 § 1, 2014)

A. All SIUs must, at a frequency determined by the director, submit no less than twice per
year, in June and December or on other dates specified, reports indicating the nature and
concentration of pollutants in the discharge that are limited by pretreatment standards, and
the measured or estimated average and maximum daily flows for the reporting period. In
cases where the pretreatment standard requires compliance with a best management
practice or pollution prevention alternative, the SIU must submit documentation required by
the director or the pretreatment standard necessary to determine the compliance status of
the SIU. The director may modify the months during which the above reports are to be
submitted.
B. All periodic compliance reports must be signed and certified by an authorized
representative of the discharging facility. (Ord. 1734 § 8, 2024; Ord. 1598 § 1, 2014)
A. All IUs must promptly notify the director in advance of any substantial changes to the
IU’s operations or system which might alter the nature, quality, or volume of its wastewater.
B. SIUs are required to notify the director immediately of any changes at its facility
affecting the potential for a slug discharge. (Ord. 1598 § 1, 2014)
All users not required to obtain an individual wastewater discharge permit shall provide
reports to the director as the director may require. (Ord. 1598 § 1, 2014)
If sampling performed by an IU indicates a violation, the IU must notify the director within
twenty-four hours of becoming aware of the violation. The IU shall also repeat the sampling
and analysis and submit the results of the repeat analysis to the city within thirty days of
becoming aware of the violation. Where the city has performed the sampling and analysis in
lieu of the IU, the city must perform the repeat sampling and analysis unless it notifies the IU
of the violation and requires the IU to perform the repeat analysis. Resampling is not
required if:
A. The city performs sampling for the IU at a frequency of at least once per month, or
B. The city performs sampling for the IU between the time the initial sampling was
conducted and the time the IU or the city receives the results of this sampling. (Ord. 1598 § 1,

A. Each IU shall provide protection from accidental discharge of prohibited materials or
other wastes regulated by this chapter. Facilities shall be provided to prevent accidental
discharges of prohibited materials and shall be maintained at the IU’s expense. Detailed
plans showing facilities and operating procedures to provide this protection shall be
submitted by the IU when requested, to the city for the city’s review, and shall be approved
by the director before construction of the facility. Review and approval of such plans and
operating procedures shall not relieve the IU from the responsibility to modify its facility as
necessary to meet the requirements of this chapter or of any other applicable rule,
regulation, order or ordinance of a governmental authority.
B. Any direct or indirect connection to the IU’s plumbing or drainage system that allows
the discharge of wastes to the public sewer system in violation of this chapter, shall be
eliminated. Where such action is impractical or unreasonable, as determined by the city, the
IU shall appropriately label such entry points to warn against discharge of such wastes.
C. A notice shall be permanently posted on the IU’s bulletin board or other prominent
place advising employees who could cause such a discharge to occur, of the emergency
notification procedure. (Ord. 1598 § 1, 2014)
All pollutant analyses, including sampling techniques, to be submitted as part of a
wastewater discharge permit application or report shall be performed in accordance with the
techniques prescribed in 40 CFR Part 136 and amendments thereto, unless otherwise
specified in an applicable categorical pretreatment standard. If 40 CFR Part 136 does not
contain sampling or analytical techniques for the pollutant in question, or where the EPA
determines that the Part 136 sampling and analytical techniques are inappropriate for the
pollutant in question, sampling and analyses shall be performed by using validated
analytical methods or any other applicable sampling and analytical procedures, including
procedures suggested by the director or other parties approved by the EPA. (Ord. 1598 § 1,
2014)
A. Samples collected to satisfy reporting requirements must be based on data obtained
through appropriate sampling and analyses performed during the period covered by the
report and be representative of conditions occurring during the reporting period.
B. Except as indicated in subsections C and D below, the IU must collect wastewater
samples using twenty-four-hour flow proportional composite sampling techniques, unless
time proportional composite sampling or grab sampling is authorized by the director. Where
time proportional composite sampling or grab sampling is authorized by the director, the
samples must be representative of the discharge. Using protocols (including appropriate

compositing procedures as documented in approved EPA methodologies may be authorized
by the city, as appropriate. In addition, grab samples may be required to show compliance
with instantaneous limits.
C. Samples for oil and grease, temperature, pH, cyanide, total phenols, sulfides, and
volatile organic compounds must be obtained using grab collection techniques.
D. For sampling required in support of baseline monitoring reports and ninety-day
compliance reports pursuant to Sections 13.08.170 and 13.08.510 (40 CFR 403.12(b) and
(d)), a minimum of four grab samples must be used for pH, cyanide, total phenols, oil and
grease, sulfide and volatile organic compounds for facilities for which historical sampling
data do not exist; for facilities for which historical sampling data are available, the director
may authorize a lower minimum. For the reports required by Section 13.08.200 (40 CFR
403.12(e) and (h)), the IU is required to collect the number of grab samples necessary to
assess and assure compliance with applicable pretreatment standards and requirements.
E. If an IU subject to the reporting requirement in this section monitors any regulated
pollutant at the appropriate sampling location more frequently than required by the director,
using the procedures set forth in Section 13.08.270, the results of this monitoring shall be
included in the report.
F. All required sampling shall be done at the IU’s expense. (Ord. 1598 § 1, 2014)
All wastewater samples must be representative of the IU’s discharge. Wastewater
monitoring and flow measurement facilities shall be properly operated, kept clean, and
maintained in good working order at all times. The failure of an IU to keep its monitoring
facility in good working order shall not be grounds for the IU to claim that sample results are
unrepresentative of its discharge. (Ord. 1598 § 1, 2014)
Written reports will be deemed to have been submitted on the date postmarked. For reports
that are not mailed, postage prepaid, from a mail facility serviced by the United States
Postal Service, the date of receipt of the report shall govern. (Ord. 1598 § 1, 2014)
Any IUs subject to the reporting requirements of this chapter shall retain, and make
available for inspection and copying, all records of information obtained pursuant to any
monitoring activities required by this chapter, any additional records of information obtained
pursuant to monitoring activities undertaken by the IU independent of such requirements,
and documentation associated with best management practices established under Section
13.08.040. Records shall include the date, exact place, method, time of sampling, the
name(s) of the person(s) taking the samples; the dates analyses were performed; who
performed the analyses; the analytical techniques or methods used; and the results of such
analyses. These records shall remain available for a period of at least three years or during
the pendency of any litigation. (Ord. 1598 § 1, 2014)

Article VIII. Publication of Users in Significant Noncompliance
A. The director shall publish annually, in a newspaper of general circulation that provides
meaningful public notice within the jurisdictions served by the POTW, a list of the IUs which,
at any time during the previous twelve months, were in significant noncompliance with
applicable pretreatment standards and requirements. The term significant noncompliance
shall be applicable to all SIUs (or any other IU that violates subsection (A)(3), (4) or (8) of
this section) and shall mean:
1. Chronic violations of wastewater discharge limits, defined here as those in which
sixty-six percent or more of all the measurements taken for the same pollutant
parameter taken during a six-month period exceed (by any magnitude) a numeric
pretreatment standard or requirement, including instantaneous limits as defined by 40
CFR 403.3(1);
2. Technical review criteria (TRC) violations, defined here as those in which thirty-
three percent or more of all of the measurements taken for the same pollutant
parameter during a six-month period equal or exceed the product of the numeric
pretreatment standard or requirement including instantaneous limits, as defined by 40
CFR 403.3(1) multiplied by the applicable TRC (TRC equals 1.4 for BOD, TSS, fats, oil
and grease, and 1.2 for all other pollutants except pH);
3. Any violation of a pretreatment effluent limit (daily maximum or longer term
average) that the city determines has caused, alone or in combination with other
discharges, interference or pass-through (including endangering the health of POTW
personnel or the general public);
4. Any discharge of a pollutant that has caused imminent endangerment to human
health, welfare or to the environment or has resulted in the POTW’s exercise of its
emergency authority as stated in this chapter to halt or prevent such a discharge;
5. Failure to meet, within ninety days after schedule date, a compliance schedule
milestone contained in a local control mechanism or enforcement order for starting
construction, completing construction, or attaining final compliance;
6. Failure to provide, within thirty days after the due date, required reports such as
baseline monitoring reports, ninety-day compliance reports, periodic self-monitoring
reports, and reports on compliance with compliance schedules;
7. Failure to accurately report noncompliance;
8. Any other violation or group of violations which the city determines will adversely
affect the operation or implementation of the local pretreatment program. (Ord. 1598 § 1,

Article IX. Sewer Connection
Before a permit shall be issued for a sewer connection in any area now outside the city
limits which shall hereafter be annexed to the city, the owner or applicant shall pay to the
city for such privilege a sum of money to be the property’s share of the cost of the existing
sewerage facilities of the city to be used by the property. (Ord. 1598 § 1, 2014)
The sum of the fee described in Section 13.08.330 shall be the equivalent of the cost to
similar properties then within the city which have paid for the facilities so to be used. (Ord.
1734 § 8, 2024; Ord. 1598 § 1, 2014)
The sum of the fee described in Section 13.08.330 shall not include any amounts from
which bonds of the city are then outstanding and to which the property shall become subject
upon annexation. (Ord. 1734 § 8, 2024; Ord. 1598 § 1, 2014)
A. Sewer mains may be extended by developers or other interested parties that would
benefit by their extension, at their cost, provided the improvements are designed to current
city standards and policy and are approved by the director of public works and director of
utilities.
B. The owner or developer who installs improvements which abut property other than that
being developed, or in a greater size or capacity than that required for the development of
the property under consideration, may be eligible for reimbursement as provided in Section
16.20.110. (Ord. 1734 § 8, 2024; Ord. 1598 § 1, 2014)
A. Payment of Costs Prior to Sewer Connection Permit Issuance. Before a permit shall be
issued for a sewer connection in any areas within the city, which property shall use any
existing city sewerage facilities which were constructed by a developer under a

reimbursement agreement for which such property shall not have made full payment of its
share of the cost thereof, the owner or applicant shall pay to the city a sum of money for
such privilege in the same manner as provided in this chapter.
B. Installation of Water Meters on Private Wells Serving Properties for Determining Sewer
Service Charges. All properties where private well water is used and associated wastewater
is discharged to the existing sewer system shall install a water meter on the well in order to
determine the appropriate sewer charges. Installation of the water meter shall be at the
private owner ’s expense in accordance with the standards established by the city engineer.
Water meters on private wells shall be owned by the city, consistent with Section 13.04.130,
and property owners shall enter into a private well metering agreement with the city for
meter reading.
C. Existing on-site septic tanks and/or leach fields may continue serving existing
structures. Where city sewer service is available, use of existing private waste disposal
systems (septic systems, leach fields, etc.) to serve new development (meaning projects
that add plumbing fixture units) will not be permitted. In the event of abandonment or failure
of the existing septic tank and/or leach field, owner shall comply with applicable state and
county regulations regarding septic system abandonment and immediately connect to the
city’s sewer system. Where city sewer facilities are not available within two hundred feet of
the parcel as defined in the Plumbing Code 713.4, the owner may be allowed to repair or
replace the failed septic system at the discretion of the utilities director and consistent with
county requirements. (Ord. 1704 § 13, 2021; Ord. 1598 § 1, 2014)
A. All sewer mains whether built on public streets or in public easements shall be
designed by a registered engineer and shall conform to the uniform design standards
adopted by the city.
B. Except in public roadways, public easements, or at the discretion of the utilities director,
where sewer infrastructure is proposed in private streets, yards, parking lots, drive aisles,
etc., sewer infrastructure shall be privately owned and privately maintained consistent with
Section 13.08.395.
C. Orderly construction and/or replacement of the city’s wastewater collection system
infrastructure shall occur with proposed development or redevelopment of a parcel within
the city limits. Wastewater collection system infrastructure shall be designed and
constructed consistent with the city’s standard specifications and engineering standards and
uniform design criteria and the applicable wastewater collection system planning documents
and policies. In lieu of construction/installation of sewer mains within the city limits, a surety
approved by the city may be provided at the discretion of the utilities director in
conformance with city bonding requirements.
D. Rain harvesting systems using an emergency overflow into the sewer must not include
drainage from roof gutters or storm capture devices. (Ord. 1704 § 14, 2021; Ord. 1598 § 1,
2014)

A. Drainage Piping Serving Fixtures. Drainage piping serving fixtures, the flood level rims
of which are located below the elevation of the curb or property line, at the point where the
building sewer crosses under the curb or property line, and above the crown level of the
main sewer, shall drain by gravity into the main sewer, and shall be protected from backflow
of sewage by installing a backwater valve that is compliant with the CPC, and each such
backwater valve shall be installed only in that branch or section of the drainage system
which receives the discharge from fixtures located below the elevation of the curb or
property line. If the drainage piping is lower than the next upstream manhole, the property
owner must install a backwater valve. It is the property owner ’s responsibility to determine
whether a backwater valve is required.
B. Director Empowered to Stop Overflow. The city is not liable for damage caused by or
resulting from a property owner ’s failure to install and maintain a CPC-compliant backwater
valve. If the property owner fails to install and maintain a backwater valve to be free of
obstruction and function as designed, when required under this section, the director may
order and require the plumbing fixture to be disconnected and removed and the outlet
plugged or capped. In the event that the property owner fails to disconnect and plug or cap
the sewer connection within ten days after written notice by the director, then the director
shall arrange for such disconnection and capping, the cost of which may be collected by
court action or may be declared to be a lien by action of the council after public hearing and
notice of the property owner and shall be added to and collected as part of the tax roll.
C. Alternate Right to Terminate Water Service. Failure to comply with this section shall be
considered an unauthorized action by the property owner. As an alternate to the procedure
set forth in subsection B of this section, if the property owner fails to install and maintain a
backwater valve in good working condition when requested under this chapter, the director
may order and require termination of water service to the parcel and all structures
connected to the sewer outlet subject to overflow. The water service shall not be reinstated
until the maintenance or installation of the backwater trap or backwater valve has been
approved by the director.
D. Maintenance of House Sewer Connections. Maintenance of house sewer connections
shall comply with Section 13.08.395(B). (Ord. 1734 § 8, 2024; Ord. 1704 § 15, 2021; Ord. 1665
§ 2, 2019; Ord. 1598 § 1, 2014)
A. Purpose. Inflow and infiltration (I/I) is a serious problem for the city in that during wet
weather events, a significant amount of water is introduced into the city’s wastewater
collection system from breaches in the public and private sewer pipeline system. Studies
have shown that private sewer laterals are a significant source of I/I for the city. The city has
determined that it is in the interest of the public’s health, safety, and welfare to address I/I
contributed by private sewer laterals and, as such, it is a city priority to require the
inspection of private sewer laterals.
B. Ownership, Maintenance, and Repair.
1. The entire lateral, from the building connection up to and including the “wye”
connection or other tie-in to the city-owned sewer main, shall fall within the owner ’s
responsibility for installation, maintenance, repair, and replacement.

2. Each property owner shall be responsible for maintenance and repair of their
private sewer lateral in compliance with this section in a safe and sanitary condition,
including:
a. Private sewer laterals shall be free of displaced joints, breaks, offsets,
structural defects, damage, open joints, missing portions of pipe, root intrusion,
cracks, leaks, sediment deposits, bellies in the pipe or any other similar conditions,
defects or obstructions likely to cause or contribute to blockage of the private
sewer lateral or the public sewer.
b. Private sewer laterals shall be equipped with cleanouts.
c. Private sewer laterals shall not be constructed, either in whole or in part, of
“Orangeburg pipe.”
d. As described in Section 13.08.030(A), it is unlawful for any individual to
connect the following to a private sewer lateral: storm drains, roof drains, yard
drains, surface or subsurface drainage, groundwater, or other non-sewage pipes or
drains.
3. If a property owner fails to maintain the abovementioned wastewater facilities in a
safe and sanitary condition, the director may order and require termination of water
service to the parcel and all structures connected to the sewer outlet subject to these
conditions. The water service shall not be reinstated until the maintenance or
installation of appropriate wastewater disposal facilities has been approved by the
director.
4. Before granting any permit authorizing construction of a private sewer lateral or
private sewer main serving multiple properties, the city shall require a private easement
setting forth responsibilities for each parcel served (including responsibility for
maintenance, inspection, and improvement of the shared sewer lateral).
C. Inspection of Existing Private Sewer Laterals.
1. Except as set forth in subsection (C)(2) of this section, after January 1, 2020, all
private sewer laterals connected to the city’s sewer system shall be inspected per
subsection F of this section at the property owner ’s sole expense, when any of the
following events occur:
a. Whenever the city has issued a notice of violation following a sanitary sewer
overflow event from a property’s private sewer lateral.
b. Upon submittal of a building permit for the addition of a bedroom, bathroom, or
kitchen in a residential structure or the addition of nonresidential space or an
additional plumbing fixture unit in nonresidential structures.
c. A change of the use of the structure from: (i) residential to nonresidential use;
(ii) to a nonresidential use that will result in a higher flow than the previous
nonresidential use; or (iii) to a nonresidential use where the structure served has
been vacant or unoccupied for more than three years.
d. Increase in size of the domestic water meter serving the property or adding a
new domestic water meter.
e. Whenever property located in the city and containing one or more structures
which are served by a private sewer lateral or laterals is subdivided. The inspection
shall occur prior to recordation of the final map.
f. Within thirty days of notification by the city that “smoke testing” or closed-
circuit television (CCTV) sewer main inspection indicates the presence of inflow or
infiltration from private property that impacts the operation of the public wastewater
https://sanluisobispo.municipal.codes/Code/13.08.020 41/53

collection system.
g. Upon any change in ownership of real property within the city, which shall be
implemented as follows:
i. “Change in ownership” shall have the meaning set forth in California
Revenue and Taxation Code Sections 60 and 61. A change in ownership shall
not include those transactions as set forth in California Revenue and Taxation
Code Section 62.
ii. Before close of escrow for any change in ownership of real property within
the city, the seller(s) of such property shall disclose to the buyer(s) the results
of the private sewer lateral inspection as set forth in subsection F of this
section.
h. For events identified in subsections (C)(1)(a) through (C)(1)(g) of this section,
repair or replacement shall be made pursuant to subsection G of this section.
i. For events identified in subsection (C)(1)(g) of this section, repair or
replacement requirements pursuant to subsection G of this section shall not be
effective until January 1, 2027.
2. Exceptions. An inspection required pursuant to subsection (C)(1) of this section
shall not be required in the following circumstances:
a. New Construction or Prior Replacement of Lateral. If the owner(s) (or the
owner ’s predecessor-in-interest) has originally installed or has replaced the private
sewer lateral within the twenty years prior to the date the inspection would
otherwise be required.
b. Prior Inspection of a Lateral. If the owner(s) (or the owner ’s predecessor-in-
interest) has completed an inspection of the sewer lateral in accordance with the
inspection requirements of subsection F of this section within the past five years.
c. The private sewer lateral is located within a common interest development
system that is not owned and operated by the city, which is regulated under
subsection D of this section and serves more than two separate units or properties
within the common interest development.
The owner shall bear the burden of proving that the inspection requirements of
subsection (C)(1) of this section do not apply. The owner shall provide proof of any
prior replacement, inspection or repair of a private sewer lateral in the form of a
validly issued permit or other documentation that ensures such prior replacement,
repair or inspection of a private sewer lateral occurred pursuant to the exceptions
above. The form and content of the document or proof must be deemed sufficient
by the city’s utilities director.
D. Private Sewer Laterals Within Common Interest Developments.
1. For purposes of this section, the term “common interest development” shall include
any community apartment project, condominium project, planned development, or stock
cooperative.
2. Private sewer laterals located within a common interest development shall be
inspected pursuant to the requirements of subsection F of this section as follows:
a. Whenever the city has issued a notice of violation following a sanitary sewer
overflow event from a common interest development’s private sewer lateral.
b. Increase in size of the water meter serving the common interest development.
https://sanluisobispo.municipal.codes/Code/13.08.020 42/53
Page 43 of 53
3. Exceptions. An inspection required pursuant to subsection (D)(2) of this section
shall not be required in the following circumstances:
a. Prior Replacement of Lateral. If the private sewer lateral serving the common
interest development in its entirety was installed or replaced within the twenty
years prior to the date the inspection would otherwise be required.
b. Prior Inspection or Repair of a Lateral. If the private sewer lateral serving the
common interest development in its entirety was inspected in accordance with the
inspection requirements of subsection F of this section within the five years prior to
the date the inspection would otherwise be required.
E. Inspection of Shared Private Sewer Laterals. Each property owner served by a shared
private sewer lateral shall be responsible for compliance with subsection B of this section
and shall be subject to the inspection requirements identified in subsection C of this section.
For purposes of this subsection E, a “shared private sewer lateral” shall mean laterals
serving more than one property that are not part of a common interest development.
F. Inspection Requirements.
1. Property owners must submit documentation of the sewer lateral inspection to the
city prior to the close of escrow. Testing may be accomplished by either a water
exfiltration test, an air test, or closed-circuit video recording observation. Installation of
cleanouts and removal of existing P-traps may be necessary to accomplish the video
inspection. If a closed-circuit video recording observation is selected as the method of
inspection, then the video shall meet the following requirements:
a. Shall be in digital format.
b. Shall be in color (black and white or otherwise unclear video will not be
accepted).
c. Shall show the address of the lateral.
d. Shall show the date the video was taken.
e. Shall inspect the entire lateral from the house connection to the city-owned
sewer main.
f. Shall have a running foot or time marker clearly visible on the screen.
g. Where joints are present, shall briefly stop the camera at each to clearly
indicate their integrity.
h. Shall have the telephone number for the point of contact for the company
providing the inspection.
i. A map shall be provided with the video inspection to clearly show the lateral
location including the cleanout or access point at the house connection used to
insert the camera into the lateral and the wye connection to the city-owned sewer
main.

3. A contractor, plumber, or a person experienced in lateral inspections who prepares
a false lateral inspection report shall be subject to punishment under Article XII of this
chapter in addition to any other legal remedies or punishment provided by law.
4. Verification. The city reserves the right to verify the sewer lateral inspection results
prior to being accepted.
G. Sewer Lateral Repair or Replacement Requirements. Upon receipt of the private sewer
lateral inspection report pursuant to this chapter, the city shall review the private sewer
lateral inspection and lateral inspection report to verify the plumber/contractor findings and
provide the owner with a determination on whether the lateral meets the criteria described in
subsection B of this section. If the private sewer lateral is not in compliance with subsection
B of this section, then it shall be repaired or replaced to conform to such standards within
one hundred eighty days of the city’s determination. If an inspection of a noncompliant
lateral was conditioned due to a sanitary sewer overflow or from findings of infiltration and
intrusion, or a lateral with defects having not met the required pipe material requirements, it
must be completely replaced rather than repaired. No person shall repair or replace a sewer
lateral without first obtaining a permit from the city.
H. Punishment for Violation of This Chapter. Violations of this article shall be punishable
pursuant to the remedies identified in Article XII of this chapter. It is considered a violation
for any property owner to have a sewer lateral system that does not comply with subsection
B of this section, unless the repair or replacement of such system is being pursued in good
faith. The city may withhold building permits or other discretionary approvals for a property
with a private sewer lateral that is determined to be not in compliance with subsection B of
this section until the private sewer lateral is brought into compliance with city standards.
Final building approval will be conditioned upon repair or replacement of any noncompliant
lateral systems to the satisfaction of the director.
I. Rebate Programs. The city may establish by resolution one or more programs to assist
owners with the replacement of private sewer laterals.
J. Fees. The city council may from time to time establish, by resolution, fees for issuing
permits, reviewing inspection reports and other activities of the city performed pursuant to
this chapter. (Ord. 1756 § 2, 2026; Ord. 1734 § 8, 2024; Ord. 1704 §§ 16—18, 2021; Ord. 1665 § 3,

Wastewater flow offset.
https://sanluisobispo.municipal.codes/Code/13.08.020 44/53
Page 45 of 53
Nothing in this chapter shall prohibit the city from imposing conditions of approval for
wastewater flow capacity offsets deemed proportional, reasonable, and necessary to protect
the public health, safety, and general welfare and ensure compliance with this chapter and
all applicable city regulations and policies.
1. Major development review entitlements and general plan and zoning amendments
citywide and moderate development review projects within wastewater system capacity
constrained areas shall be subject to engineering analysis, such as wastewater flow
estimates and wastewater flow modeling provided by the applicant with the entitlement
application to determine available sewer system capacity and the project’s effect on the
municipal wastewater collection system. Subdivision and use permit entitlements
resulting in the range of development as identified in the major and moderate
development review tiers shall be subject to this requirement.
2. The results of the engineering analysis and flow modeling shall determine
associated conditions of approval, which may include but not be limited to public or
private sewer improvements, such as upsizing sewer mains, and/or replacing private
sewer laterals to offset capacity deficiencies. (Ord. 1756 § 3, 2026; Ord. 1734 § 8, 2024;
Ord. 1704 § 19, 2021; Ord. 1665 § 3, 2019)
Article X. Charges and Fees
A. A schedule of charges and fees shall be adopted by the city by resolution and may be
amended from time to time which will enable the city to comply with the revenue
requirements of the State Clean Water Grant Program. Charges and fees shall be
determined in a manner consistent with regulations of the grant program.
B. All users shall be classified as either a significant industrial user, Class I user, or a
Class II user, according to the principal activity conducted on the user ’s premises and
appropriate nonindustrial classifications as determined by the city. The purpose of such
classification is to facilitate the regulation of wastewater discharges based on wastewater
constituents and characteristics to provide an effective means of source control, and to
establish a system of user charges and industrial user wastewater discharge permit fees
which will ensure an equitable recovery of the city’s cost for operation of the pretreatment
program.
C. The charges for each wastewater constituent and characteristic shall be established by
the city and set forth in the city’s schedule of charges and fees, which may include, but shall
not be limited to:
1. User classification charges.
2. Fees for monitoring and inspections.
3. Charges and fees based on wastewater constituents and characteristics to include
industrial cost recovery provisions of the Federal Act (i.e., PL 92-500).
4. In case a residence or place of business becomes vacant, the minimum sewer
charge shall be collected until the city is requested to shut off the water.

5. All charges for such sewage service shall be paid at the same time as water
charges are paid to the city and shall be billed upon the same water bill sent to the
user; and both amounts must be paid or the city may, in addition to other remedies,
shut off the water service.
6. Any person failing to pay the sewer service charge when due, and if the water
service has been disconnected, shall pay the water restoration-reconnection charge
provided for in Section 13.04.060.
D. When user classification charges are established, they shall be based upon a minimum
basic charge for each premises, computed on the basis of wastewater from a domestic
premises. (Ord. 1734 § 8, 2024; Ord. 1598 § 1, 2014)
Revenue derived by the city under the provisions of the ordinance codified in this chapter

Article XII. Administration and Enforcement Remedies
A. Notification of Discharge.
1. Users shall notify the director immediately upon discharging wastes in violation of
this chapter to enable countermeasures to be taken by the city to minimize damage to
the community sewer, treatment facility, treatment process, treatment personnel and
the receiving waters.
2. This notification shall be followed within fifteen days of the date of occurrence by a
detailed written statement describing the causes of the accidental discharge and the
measures being taken to prevent future occurrence.
3. Such notification will not relieve users of liability for any expense, loss or damage
to the sewer system, treatment plant, or treatment process, or other public or private
property, or for any fines imposed on the city by any public entity on account thereof.
B. Notices to Employees. In order that employees of users be informed of city
requirements, users shall make available to their employees copies of this chapter, together
with such other wastewater information and notices which may be furnished by the city from
time to time directed toward more effective water pollution control. A notice shall be
furnished and permanently posted at the premises advising employees whom to contact in
case of an accidental discharge in violation of this chapter.
C. Preventive Measures. Any direct or indirect connection or entry point for persistent or
deleterious wastes to the user ’s plumbing or drainage system should be eliminated. Where
such action is impractical or unreasonable, the user shall appropriately label such entry
points to warn against discharge of such wastes in violation of this chapter. (Ord. 1734 § 8,
2024; Ord. 1598 § 1, 2014)
A. Notice of Violation. When the director finds that a user has violated or continues to
violate, any provision of this chapter, a wastewater discharge permit or order issued
hereunder, or any other pretreatment standard or wastewater requirement of the city, state
or federal government, or is found to have improperly used or maintained sewers, the
director may serve that user a written notice of violation. Within thirty days of the receipt of
such notice, an explanation of the violation and a plan for the satisfactory correction and

prevention thereof, to include specific required actions, shall be submitted by the user to the
director. Submission of such a plan in no way relieves the user of liability for any violations
occurring before or after receipt of the notice of violation.
B. Nothing in this section shall limit the authority of the director to take any action,
including emergency actions or any other enforcement action, without issuing a notice of
violation; however, such notice of violation shall be issued as soon as possible.
C. Consent Orders. The director may enter into consent orders, assurances of
compliance, or other similar agreements with any user responsible for noncompliance. Such
agreement shall include specific actions to be taken by the user to correct the
noncompliance within the time period specified in the agreement. Such documents shall
have the same force and effect as the administrative orders issued pursuant to Sections
13.08.500 and 13.08.510 and shall be judicially enforceable.
D. Compliance Orders. When the director finds that a user has violated, or continues to
violate, any provision of this chapter, a wastewater discharge permit, or order issued
hereunder, or any other pretreatment standard or requirement, the director may issue an
order to the user responsible for the discharge directing that the user come into compliance
within a specified time. If the user does not come into compliance within the time provided,
water service may be discontinued unless adequate treatment facilities, devices, or other
related appurtenances are installed and properly operated. Compliance orders may also
contain other requirements to address the noncompliance, including additional self-
monitoring and management practices designed to minimize the amount of pollutants
discharged to the sewer. A compliance order may not extend the deadline for compliance
established for a pretreatment standard or requirement, nor does a compliance order relieve
the user of liability for any violation, including any continuing violation.
E. Cease and Desist Orders. When the director finds that a violation of this chapter has
occurred, or appears imminent, and the violation appears to present an imminent
endangerment to the health or welfare of persons, or the environment, or which threatens to
interfere with the operation of the POTW or cause pass-through, the director may, after
informal notice to the violator, issue an order to cease and desist and direct those persons
not complying with this chapter to:
1. Comply forthwith; or
2. Comply in accordance with a time schedule set forth by the director; or
3. Take appropriate remedial or preventive action in the event of a threatened
violation.
F. When the director finds that a discharge of wastewater has taken place, in violation of
prohibitions or limitations prescribed in this chapter, or wastewater source control
requirements, effluent limitations or pretreatment standards, or the provisions of a
wastewater discharge permit, the director may require the user to submit to the appropriate
POTW representative a report containing methods to eliminate illegal discharges, a time
schedule for the commencement and completion of any equipment installation or
maintenance necessary to comply with discharge limitations and methods of assurance of
continued compliance. (Ord. 1598 § 1, 2014)
A. Within five days of issuance of a notice to correct/notice of violation of this chapter, a
person receiving such notice(s) and citation may request in writing that the director review a
contested notice to correct and/or notice of violation. Director review will proceed under the
13.08.480
Appeals.
https://sanluisobispo.municipal.codes/Code/13.08.020 48/53

terms of Section 1.24.090. There is no separate right to appeal from the director ’s review or
determination on a notice of correction or violation, but any assertions of error or challenges
to the director ’s review or determination may be raised as part of any appeal from an
administrative citation pursuant to Section 1.24.100.
B. Any user, permit applicant, or permit holder affected by any decision, action or
determination, made by the director in issuing an administrative citation, may file with the
city clerk a written appeal within ten days of such decision, action or determination, setting
forth in detail the facts supporting the appeal, in accordance with Section 1.24.100. The
appeal shall include a statement whether the appellant elects either to proceed with a
hearing officer (if no writ will be sought) or to the administrative review board (if the
appellant intends to challenge city action by writ), pursuant to Section 1.24.100(B)(2). The
request for appeal shall be deemed filed on the date received by the city clerk. If no appeal
is filed within ten days of the effective date of the administrative citation, the administrative
citation shall be deemed final.
C. The appeal will be heard either by a hearing officer or the administrative review board,
by appellant’s election, by the procedure set forth in Sections 1.24.110 through 1.24.130.
D. The notice of the decision by either the hearing officer or administrative review board or
construction board of appeals is final and is not subject to appeal to the city council. The
appellant may seek judicial review pursuant to Section 1.24.140. (Ord. 1734 § 8, 2024; Ord.
1598 § 1, 2014)
The actions and remedies available to the director in the sections set forth in this article may
be utilized separately or in combination by the director as it deems appropriate. (Ord. 1598
§ 1, 2014)
The director is authorized to seek injunctive relief to halt the noncompliance by any
industrial user with any pretreatment standard or requirement under this chapter, or permit
issued hereunder. (Ord. 1598 § 1, 2014)
Any person who discharges or causes to be discharged any water or wastewater in violation
of this chapter and such discharge, either singly or by interaction with other discharges,
results in damage to or is otherwise detrimental to or adversely affects the POTW, city
property, city storm drain system or waters of the state shall be liable to the city for
expenses necessary to correct that damage, detriment or adverse effect. The expenses
may include, but are not limited to, costs for labor, material, inspection and overhead. Any
expenses resulting from the investigation of unlawful discharges shall be collected from the
responsible party. In addition, any monetary penalties imposed against the city shall also be
costs for which the violator is liable to the city. (Ord. 1734 § 8, 2024; Ord. 1598 § 1, 2014)

Any person who knowingly makes any false statements, representation, record, report, plan
or other document filed with the director, or who falsifies, tampers with or knowingly renders
inaccurate any monitoring device or method required under this chapter shall be guilty of a
misdemeanor. (Ord. 1598 § 1, 2014)
The director may revoke any wastewater discharge permit, or terminate or cause to be
terminated wastewater and/or water service to any premises if a violation of any provision of
this chapter is found to exist or if a discharge of wastewater causes or threatens to cause a
condition of contamination, pollution or nuisance as defined in this chapter. This provision is
in addition to other statutes, rules or regulations, authorizing termination of services for
delinquency in payment. (Ord. 1598 § 1, 2014)
Article XIII. Affirmative Defenses to Discharge Violations
A. For the purposes of this section, “upset” means an exceptional incident in which there
is unintentional and temporary noncompliance with categorical pretreatment standards
because of factors beyond the reasonable control of the user. An upset does not include
noncompliance to the extent caused by operational error, improperly designed treatment
facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or
improper operation.
B. An upset shall constitute an affirmative defense to an action brought for noncompliance
with categorical pretreatment standards if the requirements of subsection C of this section
are met.
C. A user who wishes to establish the affirmative defense of upset shall demonstrate,
through properly signed, contemporaneous operating logs, or other relevant evidence that:
1. An upset occurred and the user can identify the cause(s) of the upset;
2. The facility was at the time being operated in a prudent and workman-like manner
and in compliance with applicable operation and maintenance procedures; and
3. The user has submitted the following information to the director within twenty-four
hours of becoming aware of the upset (if this information is provided orally, a written
submission must be provided within five days):
a. A description of the indirect discharge and cause of noncompliance;
b. The period of noncompliance, including exact dates and times or, if not
corrected, the anticipated time the noncompliance is expected to continue; and
c. Steps being taken and/or planned to reduce, eliminate, and prevent
recurrence of the noncompliance.

D. In any enforcement proceeding, the user seeking to establish the occurrence of an
upset shall have the burden of proof.
E. Users shall have the opportunity for a judicial determination on any claim of upset only
in an enforcement action brought for noncompliance with categorical pretreatment
standards.
F. Users shall control production of all discharges to the extent necessary to maintain
compliance with categorical pretreatment standards upon reduction, loss, or failure of its
treatment facility until the facility is restored or an alternative method of treatment is
provided. This requirement applies in the situation where, among other things, the primary
source of power of the treatment facility is reduced, lost, or fails. (Ord. 1598 § 1, 2014)
A user shall have an affirmative defense to an enforcement action brought against it for
noncompliance with the general prohibitions in Section 13.08.040(A) or the specific
prohibitions in Sections 13.08.040(B) through (J) if it can prove that it did not know, or have
reason to know, that its discharge, alone or in conjunction with discharges from other
sources, would cause pass-through or interference and that either:
A. A local limit exists for each pollutant discharged and the user was in compliance with
each limit directly prior to, and during, the pass-through or interference; or
B. No local limit exists, but the discharge did not change substantially in nature or
constituents from the user ’s prior discharge when the city was regularly in compliance with
its NPDES permit, and in the case of interference, was in compliance with applicable sludge
use or disposal requirements. (Ord. 1734 § 8, 2024; Ord. 1598 § 1, 2014)
A. For the purposes of this section:
1. Bypass means the intentional diversion of wastestreams from any portion of a
user ’s treatment facility.
2. Severe property damage means substantial physical damage to property, damage
to the treatment facilities which causes them to become inoperable, or substantial and
permanent loss of natural resources which can reasonably be expected to occur in the
absence of a bypass. Severe property damage does not mean economic loss caused
by delays in production.
B. A user may allow any bypass to occur which does not cause pretreatment standards or
requirements to be violated, but only if it also is for essential maintenance to assure efficient
operation. These bypasses are not subject to the provision of subsections C and D of this
section.
C. Bypass Notifications.
1. If a user knows in advance of the need for a bypass, it shall submit prior notice to
the director, at least ten days before the date of the bypass, if possible.

13.08.560
Bypass.
https://sanluisobispo.municipal.codes/Code/13.08.020 51/53
Page 52 of 53
2. A user shall submit oral notice to the director of an unanticipated bypass that
exceeds applicable pretreatment standards within twenty-four hours from the time it
becomes aware of the bypass. A written submission shall also be provided within five
days of the time the user becomes aware of the bypass. The written submission shall
contain a description of the bypass and its cause; the duration of the bypass, including
exact dates and times, and, if the bypass has not been corrected, the anticipated time it
is expected to continue; and steps taken or planned to reduce, eliminate, and prevent
reoccurrence of the bypass. The director may waive the written report on a case by
case basis if the oral report has been received within twenty-four hours.
D. Bypass.
1. Bypass is prohibited, and the director may take an enforcement action against a
user for a bypass, unless:
a. Bypass was unavoidable to prevent loss of life, personal injury, or severe
property damage;
b. There were no feasible alternatives to the bypass, such as the use of auxiliary
treatment facilities, retention of untreated wastes, or maintenance during normal
periods of equipment downtime. This condition is not satisfied if adequate back-up
equipment should have been installed in the exercise of reasonable engineering
judgment to prevent a bypass which occurred during normal periods of equipment
downtime or preventive maintenance; and
c. The user submitted notices as required under subsection C of this section.
2. The director may approve an anticipated bypass, after considering its adverse
effects, if the director determines that it will meet the three conditions listed in
subsection (D)(1) of this section. (Ord. 1598 § 1, 2014)
Article XIV. Miscellaneous Provisions
If any section, subsection, sentence, clause or phrase in this chapter is for any reason held
to be invalid or unconstitutional by a decision of any court of competent jurisdiction, such
decision shall not affect the validity of the remaining portions of these chapters. The city
council hereby declares that it would have passed the ordinance codified in this chapter,
and each and every section, subsection, sentence, clause or phrase not declared invalid or
unconstitutional without regard to whether any portion of this chapter would be subsequently
declared invalid or unconstitutional. (Ord. 1598 § 1, 2014)
