ISSUE
State Law and District Code require that a public hearing be held to receive public comment on ordinances
which revise District Code.
BACKGROUND
District Code Section 6.12.040 - Capacity Fee Program (Residential Capacity Fees)
Senate Bill 477 made certain revisions to the California Government Code which revised the section
numbers for sections relating to Accessory Dwelling Units orADUs. The bill included an urgency clause
which caused the changes to take effect on March 25, 2024. Central San references those section
numbers in our District Code. As the section numbers have changed in the Government Code, it is
appropriate to revise the references in Central San's District Code to match the updated section numbers.
District Code Section 10.04.020 and 10.04.030 - Source Control (Pretreatment) - (Definitions and
Abbreviations)
May 21, 2024 Regular FINANCE Committee Meeting Agenda Packet - Page 131 of 190
Page 2 of 23
Staff believes that it is appropriate to add a definition for the Cross -Media Electronic Reporting Rule or
CROMERR and to add the corresponding abbreviation to District Code.
District Code Section 10.32.035 - Source Control (Pretreatment) - (Interceptor/Trap Maintenance
Standards)
Staff believes that it is appropriate to make two minor revisions to Section 10.32.035. The first revision
extends a requirement regarding accumulated grease and solid waste to include traps. The second
revision deletes a requirement that traps be cleaned at least once every ninety days. Note that District
Code retains requirements that grease traps be cleaned according to manufacturers' recommendations
and that all liquids and solids be pumped and removed from grease traps by a licensed and permitted
waste hauler at least once every 90 days.
ALTERNATIVES/CONSIDERATIONS
The Board of Directors (Board) could choose to give staff different direction on the proposed revisions to
District Code.
FINANCIAL IMPACTS
No financial impacts are anticipated by this action.
COMMITTEE RECOMMENDATION
The Finance Committee reviewed this matter at its May 21, 2024 meeting and recommended

REVISING DISTRICT CODE
CHAPTERS 6.12.040, 10.04.020, 10.04.030, and 10.32.035
WHEREAS, the Central Contra Costa Sanitary District (Central San) has determined
that there is a need to update certain provisions within Chapters 6 and 10 of the District
Code; and
WHEREAS, a public hearing was noticed pursuant to Government Code Sections
50022.3 and 6066 for June 10, 2024 at 2:30 p.m. at the District Board of Directors
Regular Meeting scheduled for that date; and
WHEREAS, a properly noticed public hearing was held on June 10, 2024 at 2:30 p.m.
where all interested parties were given an opportunity to be heard, and thereupon the
public hearing was closed; and
WHEREAS, the District Counsel has reviewed these proposed Code revisions and
concluded that adoption of these Code modifications does not constitute a California
Environmental Quality Act (CEQA) Project as defined under Title 14 of California Code
of Regulations; specifically it does not constitute a Project pursuant to §§ 15378(b)(2),
(4) and (5) because:
i) this action is continuing administrative in nature, and deals with general
policy and procedure making; and
ii) it does not create any governmental funding mechanism or fiscal activity
involving a commitment to any specific project; and
iii) it is an organizational and administrative activity that will not result in any
direct or indirect changes to the environment; and
WHEREAS, the Board of Directors duly considered all oral and documented evidence.
NOW, THEREFORE, the Board of Directors of the Central Contra Costa Sanitary
District does ordain as follows:
Amendment of Section 6.12.040 C

iii. The written authorization is submitted to the District.
C. "Best management practices (BMPs)" means schedules of activities, prohibitions
of practices, maintenance or operating procedures, and other management
practices to implement that which is listed in 40 CFR 403.5(a)(1) and to prevent
or reduce the pollution of "waters of the United States." BMPs also include
treatment requirements, operating procedures, and practices to control plant site
runoff, spillage or leaks, sludge or waste disposal, or drainage from raw materials
storage. Best management practices may be proposed by an individual user and
accepted by the District or, as set forth in this title, mandated and set by the
District.
D. "Biochemical oxygen demand (BOD)" means the quantity of oxygen utilized in
the biochemical oxidation of organic matter under standard laboratory procedure,
five days at twenty degrees centigrade expressed in terms of weight and
concentration (milligrams per liter, mg/1).
E. "Carbonaceous biochemical oxygen demand (CBOD)" means the quantity of
oxygen utilized in the biochemical oxidation of organic matter, excluding
oxidation due to nitrogenous bacteria, under standard laboratory procedure, five
days at twenty degrees centigrade expressed in terms of weight and
concentration (milligrams per liter, mg/1).
F. "Categorical standards" means national pretreatment standards which specify
quantities or concentrations of pollutants or pollutant properties that may be
discharged by industrial users in specified industrial subcategories.
G. "Class I industrial user" means any nondomestic user who requires a significantly
greater level of administrative services and/or oversight by the District
Environmental Compliance Program than a Class II user, based on the unusual
character of the wastewater due to its volume, strength, composition, or its
derivation from a hazardous waste or substance, or the potential variability in the
character of the wastewater, or on the potential for increased administrative cost
to the District due to the unusual character of the waste.
H. "Class II industrial user" means any nondomestic user of the District's facilities
who-
1. Has a discharge flow of twenty-five thousand gallons or more per average
work day; or
2. Contributes process wastewater which makes up five percent or more of
the District treatment plant's average dry weather hydraulic or organic
capacity; or

District to meet the objectives of this title or for violating any pretreatment
standard or requirement.
I. "Class III industrial user" means any nondomestic user who may, in the opinion
of the District, have an impact on the District's ability to meet the objectives of
this title. This impact may be of a lesser degree than for a Class II industrial user
due to the volume, characteristics, or the nature of the process producing the
waste. Any non -domestic user who generates hazardous waste, whether or not
said waste is, in the normal course of the industrial process, discharged into the
sanitary sewer system, may be considered a Class III industrial user. A
nondomestic user may be classified as a Class III Industrial user if any of the
hazardous waste is being discharged into the sewer, or if, in the opinion of the
District, there is a potential for this waste to be discharged into the sewer, even
through accident in non -process or process of handling of the waste. This
classification applies to, but is not limited to, those industrial users who are not
designated as Class I or Class II users and who are required to have a county
hazardous waste facility license. This Class III industrial user category shall also
include industrial users who store or use hazardous materials, whether or not a
hazardous waste is produced in the industrial or commercial process if, in the
determination of the District, a potential exists for a significant impact upon the
District facilities due to a release of these materials into the environment. This
classification also applies to those industrial users not designated as Class I or
Class II industrial users who are required by statute or county regulations to have
a hazardous materials response plan and inventory. A Class III industrial user
shall also include all varieties of nondomestic users for which the general
pretreatment regulations promulgated by the EPA under a 40 CFR 403.8(f)(2)(iii)
may require the District to provide an industrial user (IU) notification regarding
the applicability of RCRA requirements. Class III industrial users may be
individually designated by the District based on the criteria set forth above or on
categorization of the user as a member of a particular business category.
J. "Class IV industrial user" means any non -domestic user who is not included
within the definitions and parameters of Class I, Class II, or Class III industrial
users.
K. "Collection system" means the District pipelines, pump stations, manholes, and
other similar facilities which accept, collect, and convey sanitary sewage to the
treatment plant.
L. "Constituent" means a pollutant parameter that may be subject to monitoring or
other control measures by a user.

garages, grease traps serving only a trash enclosure without a wash
station) shall be cleaned at least once every year). Less frequent cleaning
shall be subject to District approval through the interceptor/trap
maintenance variance.
5. Finding of No "Project"
The District Board's action in adopting the proposed Code revisions does not constitute
a Project as envisioned by CEQA, as this action is consistent with defined
circumstances which do not constitute a Project pursuant to the provisions of Title 14

6.12.040 - Residential capacity fees.
A. Policy. Any new residential connection shall be subject to payment of capacity fees in an
amount which will fund its proportionate share of the cost of District services and
needed upgrades, replacements, renovations and improvements of existing District
wastewater and household hazardous waste collection, treatment, recycling, reuse and
disposal facilities to maintain their capacity, and to add to and/or expand these facilities
in the future when needed, all of which services and facilities will ultimately be shared
by current and future users. These facility costs shall be estimated pursuant to the
policies and findings set forth within this chapter.
B. Basis for Capacity Fees. Capacity fees for residential units shall be set from time to time
as provided in this chapter based on the District's determination of the then -current
value of all District assets divided by the then -current number of residential unit
equivalents receiving District wastewater utility service. The residential unit fees
established pursuant to the provisions of this chapter shall be representative of both the
volume of flow and strength characteristics for an average residential unit as determined
by wastewater industry standards and specific studies undertaken by the District and
other sewering entities.
C. Capacity Fees for Accessory Dwelling Units (ADUs), as defined in Title 71 Division 1,
Chapter 13 Article 2 of the California Government Code [Section 66313 et seg.6 01
2],
which includes efficiency units as defined in 17958.1 of the Health and Safety Code,
shall conform to the requirements therein. "Existing Space" is defined as space for
which a building permit has been issued, all conditions of the building permit have been
satisfied, and the building permit has been closed for at least three years.
D. Other Additional Residential Units not meeting the criteria forADUs. Each residential
unit shall be subject to each of the residential unit fees for the zone within which the
residential unit is located as set forth in this chapter.
In the event a separate additional residential unit is constructed on a parcel, whether or
not in compliance with applicable government regulations, additional capacity fees for
that residential unit shall become due. The creation of a dwelling space that
accommodates an additional separate living area within a parcel, whether or not said
additional separate living area is constructed within the original building or is a detached
building, shall subject the parcel to assessment of applicable additional residential unit
fees. An additional separate living area shall be defined as an area designed for the
purpose of separate habitation that (1) will be, or can be, physically separated by a wall
or door from other residential units on the parcel, and (2) contains a full bathroom
consisting of a sink, a toilet, and a shower or a tub; an additional sink located outside
the bathroom area; a multipurpose or bedroom area; and an exterior entrance. The time
for payment of capacity fees for the added burden arising from the construction of a
separate additional residential unit shall be as set forth in Section 6.12.030(D) (Time for
Payment and Penalties for Delinquent Payment).

a principal business function, or any other person who performs similar policy- or
decision -making functions for the corporation, or
The manager of one or more manufacturing, production, or operating facilities,
provided, the manager is authorized to make management decisions which govern
the operation of the regulated facility, including having the explicit or implicit duty
of making major capital investment recommendations, and initiate and direct
other comprehensive measures to assure long-term environmental compliance
with environmental laws and regulations; can ensure that the necessary systems
are established or actions taken to gather complete and accurate information for
control mechanism requirements; and where authority to sign documents has
been assigned or delegated to the manager in accordance with corporate
procedures.
By a general partner or proprietor if the industrial user is a partnership or sole
proprietorship respectively.
By a duly authorized representative of the individual designated in paragraph 1 or 2 of
this section if:
The authorization is made in writing by the individual described in paragraph 1 or

position of equivalent responsibility, or having overall responsibility for
environmental matters for the company; and
iii. The written authorization is submitted to the District.
C. "Best management practices (BMPs)" means schedules of activities, prohibitions of practices,
maintenance or operating procedures, and other management practices to implement that
which is listed in 40 CFR 403.5(a)(1) and to prevent or reduce the pollution of "waters of the
United States." BMPs also include treatment requirements, operating procedures, and

the biochemical oxidation of organic matter, excluding oxidation due to nitrogenous bacteria,
under standard laboratory procedure, five days at twenty degrees centigrade expressed in
terms of weight and concentration (milligrams per liter, mg/1).
F. "Categorical standards" means national pretreatment standards which specify quantities or
concentrations of pollutants or pollutant properties that may be discharged by industrial
users in specified industrial subcategories.
G. "Class I industrial user" means any nondomestic user who requires a significantly greater level
of administrative services and/or oversight by the District Environmental Compliance Program
than a Class II user, based on the unusual character of the wastewater due to its volume,
strength, composition, or its derivation from a hazardous waste or substance, or the potential
variability in the character of the wastewater, or on the potential for increased administrative
cost to the District due to the unusual character of the waste.
H. "Class II industrial user" means any nondomestic user of the District's facilities who:
1. Has a discharge flow of twenty-five thousand gallons or more per average work day; or
2. Contributes process wastewater which makes up five percent or more of the District
treatment plant's average dry weather hydraulic or organic capacity; or
3. Has in its wastes hazardous pollutants; or

either singularly or in combination with other contributing industries, the District's
treatment plant or the ability of the District to meet the objectives of this title or for
violating any pretreatment standard or requirement.
"Class III industrial user" means any nondomestic user who may, in the opinion of the District,
have an impact on the District's ability to meet the objectives of this title. This impact may be
of a lesser degree than for a Class II industrial user due to the volume, characteristics, or the
nature of the process producing the waste. Any non -domestic user who generates hazardous
waste, whether or not said waste is, in the normal course of the industrial process, discharged
into the sanitary sewer system, may be considered a Class III industrial user. A nondomestic
user may be classified as a Class III Industrial user if any of the hazardous waste is being
discharged into the sewer, or if, in the opinion of the District, there is a potential for this
waste to be discharged into the sewer, even through accident in non -process or process of
handling of the waste. This classification applies to, but is not limited to, those industrial users
who are not designated as Class I or Class II users and who are required to have a county
hazardous waste facility license. This Class III industrial user category shall also include
industrial users who store or use hazardous materials, whether or not a hazardous waste is
May 21, 2024 Regular FINANCE Committee Meeting Agenda Packet - Page 146 of 190
Page 17 of 23
produced in the industrial or commercial process if, in the determination of the District, a
potential exists for a significant impact upon the District facilities due to a release of these
materials into the environment. This classification also applies to those industrial users not
designated as Class I or Class II industrial users who are required by statute or county
regulations to have a hazardous materials response plan and inventory. A Class III industrial
user shall also include all varieties of nondomestic users for which the general pretreatment
regulations promulgated by the EPA under a 40 CFR 403.8(f)(2)(iii) may require the District to
provide an industrial user (IU) notification regarding the applicability of RCRA requirements.
Class III industrial users may be individually designated by the District based on the criteria set
forth above or on categorization of the user as a member of a particular business category.
"Class IV industrial user" means any non -domestic user who is not included within the
definitions and parameters of Class I, Class II, or Class III industrial users.

10.32.035 Interceptor/trap maintenance standards.
Maintenance standards shall be conducted by users in order to ensure the proper operation of
interceptors and traps. If the operations of a specific user modify the need to follow the specified
standards, the user can request a variance from the District in writing on the form provided by the District.
Unless the District issues a written variance to a user, the user is responsible for meeting the specified
minimum maintenance standards of this section:
A. Access to interceptors and traps shall be maintained to allow inspection and maintenance to be
performed. Inspections shall be performed at appropriate frequency to ensure adequate
operation of the interceptor or trap and to evaluate effectiveness of best management practices
to control sources of pollutants.
B. Interceptors and traps shall be operated so that the accumulated grease and solid waste does
not meet or exceed twenty-five percent of the unit's capacity. Determinations shall normally be
made by measuring the depth of the layers within a unit.
C. Interceptors andtraps shall be cleaned at least once every ninety days. Interceptor cleaning shall
be conducted to pump all the liquid and solid contents of the unit, and the sides will be cleaned
of any substantial build-up of grease and solid wastes.
Incidental use separators (e.g. sand/oil interceptors serving parking garages, grease traps
serving only a trash enclosure without a wash station) shall be cleaned at least once every
year). Less frequent cleaning shall be subject to District approval through the
interceptor/trap maintenance variance.
D. Traps shall be cleaned according to the manufacturer's recommended frequency (e.g. daily,
weekly) when conducted by user's employees, and shall be pumped of all the liquid and solid
contents using a licensed and permitted waste hauler at least once every ninety days.
The user may clean smaller traps in lieu of using a licensed and permitted waste hauler at
least once every ninety days provided that all the standards for cleaning traps are met,
including, but not limited to, removal of all liquids and solids and not decanting wastes. The
user shall document the proper disposal of the wastes removed from the trap as required
in Section 10.32.035.G.
Decanting of wastes removed from an interceptor or trap is prohibited when a licensed and
permitted waste hauler is used to clean a unit. Wastes removed from the interceptor or trap
shall not be reintroduced into the unit cleaned or any other connection to the District's sewer
collection system unless the location is specifically authorized in a current waste hauler permit.
Introduction of enzymes, microbes, chemicals, or other materials to interceptors and traps for
the treatment of grease, oils or accumulated materials in the interceptor or trap is prohibited.
Use of such materials to treat drain lines served by an interceptor (not traps) are acceptable
provided the dosage is appropriate for the drain line cleaning and not for the removal of grease
from the interceptor.
G. The user shall maintain records documenting proper maintenance of the interceptor or trap. The
disposal location (name, address, phone number for off -site facilities) for wastes removed from
an interceptor or trap shall be recorded and made available for inspection upon request.
