A.
The rules and regulations set forth in this chapter shall be in addition to the Uniform Codes (Title 15) of the Stockton Municipal Code and in no way diminish the authority set forth therein.
B.
No
user shall contribute or cause to be contributed directly or indirectly,
any pollutant or wastewater which will interfere with the operation
or performance of the POTW. These general provisions apply to all
such users of the POTW whether or not the user is subject to National
Categorical Pretreatment Standards or any other national, State or
local pretreatment standards or requirements.
C.
For
the purpose of verifying compliance with this section, the Director
and/or the Director's designated representative may use a single grab
sample collected from any tank, treatment unit and sink, holding tank,
trench, sump, process or other device which may discharge waste to
the sanitary sewer. The above sample may be collected at the source
of discharge prior to the dilution with any other streams.
D.
A user
may not contribute the following substances to any POTW:
1.
Pollutants
introduced into POTWs by a nondomestic source shall not pass through
the POTW or interfere with the operation or performance of the POTW.
These general prohibitions and the specified prohibitions in this
section apply to all nondomestic sources introducing pollutants into
a POTW whether or not the source is subject to other national pretreatment
standards or any national, State, or local pretreatment requirements.
2.
Any
liquids, solids or gases which by reason of their nature or quantity
within the waste stream are, or may be, sufficient, either alone or
by interaction with other substances, to cause fire or explosion,
cause the waste stream to have a closed cup flashpoint of less than
140 degrees F or 60 degrees C when tested following the procedures
and methods specified in 40 CFR 261.21, or may be injurious in any
other way to the POTW or to the operation of the POTW. At no time
shall two successive readings on an explosion hazard meter at the
point of discharge into the system (or at any point in the system)
be more than 5% nor any single reading more than 10 percent of the
lowest explosive limit (LEL) of the meter. Prohibited materials include,
but are not limited to, gasoline, kerosene, naphtha, benzene, toluene,
xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorates,
perchlorates, bromates, carbides, hydrides, and sulfides.
3.

sewer or other interference with the operation of the wastewater treatment
facilities.
4.
Any
wastewater having a pH less than 5.0, more than 10.0, or in excess
of the limitations specified in any more stringent permit or regulation
or wastewater the user knows or has reason to know has any other corrosive
property capable of causing damage or hazard to structures, equipment
and/or personnel of the POTW. Excursions in pH greater than 10.0 but
less than 12.5 may be allowed providing the duration of these excursions
does not exceed:
5.
Any
waste defined as hazardous by any definition set forth in any Federal,
State, or local regulation, statute, or ordinance, unless such waste
has been delisted or decertified by the agency having authority to
do so or a variance has been granted by the appropriate Federal, State,
or local agency, including provisions for discharge to the City sewer,
which variance must be approved by the Director.
6.
Any
wastewater containing toxic pollutants in sufficient quantity, either
singly or by interaction with other pollutants, to injure or interfere
with any wastewater treatment process, constitute a hazard to humans
or animals, create a toxic effect in the receiving waters of the POTW,
or to exceed the limitation set forth in a categorical pretreatment
standard. A toxic pollutant shall include, but not be limited to,
any pollutant identified pursuant to the Act.
7.
Any
noxious or malodorous liquids, gases, or solids which, either singly
or by interaction with other wastes, are sufficient to create a public
nuisance or hazard to life or health, or is sufficient to prevent
entry into the sewerage system for maintenance and repair.
8.
Any
substance which may cause the POTW's effluent or any other product
of the POTW such as residues, sludges or scums, to be unsuitable for
reclamation and reuse or to interfere with the reclamation process.
In no case shall a substance discharged to the POTW cause the POTW
to be in noncompliance with sludge use or disposal criteria, guidelines
or regulations developed under the Act; any criteria, guidelines,
or regulations affecting sludge use or disposal developed pursuant
to the Solid Waste Disposal Act, or State criteria applicable to the
sludge management method being used.

of discharge.
12.
Any pollutants, including oxygen-demanding pollutants (BOD, etc.),
released at a flow rate and/or pollutant concentration which a user
knows or has reason to know will cause interference to the POTW unless
the user was in compliance with local limits applicable to its discharge
or, if no local limits for parameters discharged exist, can demonstrate
that its discharge directly prior to and during the instance of pass
through or interference, did not change substantially from its prior
discharges when the POTW was in compliance with its NPDES permit.
In no case shall a sudden unexpected discharge have a flow rate or
contain concentrations or qualities of pollutants that exceed, for
any period longer than 15 minutes, more than five times the average
24-hour concentration, quantities, or flow during normal operation.
13.

a manner that they could be discharged to the POTW. All floor drains
located in process or materials storage areas must discharge to the
industrial user's pretreatment facility before connecting to the POTW.
F.
The
City may approve the temporary discharge of such water only when no
reasonable alternate method of disposal is available.
G.
When
the Director determines that a user(s) is contributing to the POTW
any of the above-enumerated substances in such amounts as to interfere
with the operation of the POTW, the Director may take such action
as deemed necessary to correct the interference with the POTW.
(Ord. 2015-12-08-1601 C.S. § 2)
The quantity of waste to be discharged from an industry shall
be limited to the capacity of the existing public sewerage facilities

No
user who commences contribution to the POTW after the effective date
of the ordinance codified in this chapter shall be permitted to introduce
pollutants into the system until accidental discharge procedures and
slug load plans have been approved by the City. Review and approval
of such plans and operating procedures shall not relieve the user
from the responsibility to modify the user's facility as necessary
to meet the requirements of this chapter. Users are required to notify
the Director immediately of any changes at its facility affecting
the potential for a slug discharge. In the case of an accidental or
slug load discharge, it is the responsibility of the user to immediately
notify the POTW of the incident. Notification shall identify the location
of the discharge, the type, concentration, and volume of waste, and
corrective actions taken and/or anticipated.
B.
Written
Notice. Within five calendar days following an accidental or slug
load discharge, the user shall submit to the Municipal Utilities Department
a detailed written report describing the cause of the discharge and
the measures to be taken by the user to prevent similar future occurrences.
Such notification shall not relieve the user of any expense, loss,
damage or other liability which may be incurred as a result of damage
to the POTW, fish kills, or any other damage to person or property;
nor shall such notification relieve the user of any fines, civil penalties,
or other liabilities which may be imposed by this chapter or other
applicable law.
C.
Notice
to Employees. A notice shall be posted on the user's bulletin board
or other prominent place advising employees who to call in the event
of an accidental or slug load discharge. Employers shall insure that
all employees who may cause such an accidental or slug load discharge
to occur are advised of emergency notification procedures.
(Ord. 2015-12-08-1601 C.S. § 2)
A user proposing to discharge holding tank waste into a sanitary
sewer must secure prior written approval 90 calendar days prior to
the anticipated discharge, or at such other time as prescribed by
the Director. Unless allowed by the City under the terms and conditions
of the approval, a separate written approval must be secured for each
separate discharge. Application to the City will state the specific
location of the discharge, the time of day the discharge is to occur,
the volume of the discharge and the wastewater constituents and characteristics
of the discharge. If approval is granted for the discharge of such
waste into a sanitary sewer, the user shall pay the applicable user
charges and fees and shall meet such other conditions as required
by the City.
