No person shall discharge, deposit, or throw, or cause, allow
or permit to be discharged, into any public sewer or plumbing fixture
or to any drain, manhole, culvert, catchbasin, sanitary catchbasin,
or private sewer which connects to the sewerage system, any substance
of any kind whatsoever tending to obstruct or injure the sewerage
system, or cause a nuisance, or which shall in any manner interfere
with the proper repair or maintenance of the sewerage system, or which
shall in any way render it difficult for any workmen to operate or
repair the sewerage system, or render it impossible to meet the effluent
or solid residues disposal requirements which may be set by the regional
water quality control board, including, but not limited to, any discharge
of waste into the sewerage system which causes, threatens to cause,
or is capable of causing, either alone or by interaction with other
substances, any of the following:
B. Obstruction
of the flow in, or injury to, the sewerage system, or any portion
thereof;
C. Danger
to the life or safety of any person;
D. Condition
inhibiting or preventing the effective maintenance or operation of
the sewerage system;
E. Strong
or offensive odor, air pollution, or any noxious, toxic or malodorous
gas or substance, or gas-producing substances;
F. Interference
with the wastewater treatment process, or excessive collection or
treatment costs;
G. Use
of a share of the capacity of the sewerage system in excess of that
permitted;
H. Interference
with any wastewater reclamation process which does or may operate
in conjunction with the sewerage system, or any overloading or breakdown
of such reclamation process, or excessive reclamation costs, or which
results in any product of the treatment process which renders such
reclamation process impracticable or infeasible under normal operating
conditions;
I. Detrimental
environmental impact, or a nuisance wherever located or a condition
unacceptable to any public agency having regulatory jurisdiction over
operation of the sewerage system;
J. Discoloration,
or any other adverse condition in the quality of the effluent from
the sewerage system such that discharge wastewater quality requirements
established by any applicable law, rule, regulation, chapter, or permit
condition cannot reasonably be met by the treatment works; or
K. Conditions
at or near the sewerage system, or any portion thereof, which cause,
or may cause, the city or the district to be in violation of the requirements
of any applicable law, rule, regulation, chapter or permit.
(Prior code § 2-15.40.01; Ord. 1082 § 2, 1983)
All sewage shall be discharged to the sewerage system except
as provided in this chapter. Discharge shall be through a city-approved
sewer connection to a service lateral unless a special permit has
been issued by the director to allow direct discharge into a manhole
or other part of the sewerage system.
(Prior code § 2-15.40.02; Ord. 1082 § 2, 1983)
A. Protection
from Accidental Discharge. As required by the director, users shall
provide protection from accidental discharges of prohibited materials
or other wastes regulated by this chapter. Facilities to prevent accidental
discharge of prohibited materials shall be provided and maintained
at the user's expense. Detailed plans showing facilities and
operating procedures to provide this protection shall be submitted
to the city for review and shall be approved by the city prior to
construction of the facility. The review and approval of such plans
and operating procedures shall in no way relieve the user of the responsibility
for modifying the facility as required by the city to provide the
protection necessary to meet the requirements of this chapter.
B. Notification
Required. All users shall notify the director and the treatment plant
by telephone immediately upon accidentally discharging, or discovering
the discharge of, wastes in violation of this chapter so that the
city and/or the district may take countermeasures to minimize damage
to the sewerage system, treatment plant, treatment process and the
receiving waters. The telephone notification shall be followed within
15 days of the date of occurrence by a detailed written statement,
delivered to the director, describing the cause of the accidental
discharge and the measures being taken to prevent similar future occurrences.
Such notification shall not relieve the user of liability for any
loss, cost or expense incurred by the city and/or district as a result
of such discharge, including, without limitation, loss or damage to
the sewerage system, treatment plant or treatment process and any
fines imposed by any agency of the city and/or district on account
thereof.
C. Notice
to Employees. The director may require that notice be permanently
posted on a bulletin board in the offices of each commercial and/or
industrial user, and shall require similar posting by each major contributing
industry, advising such user's employees of the numbers to call
in case of an accidental discharge in violation of this chapter.
(Prior code § 2-15.40.03; Ord. 1082 § 2, 1983)
No person shall discharge, cause to be discharged, or permit
to be discharged into the sewerage system any stormwater, ground water,
rainwater, street drainage, subsurface drainage, swimming pool drainage,
roof runoff, yard drainage, water from irrigation, water from cooling
condensers, unpolluted industrial process water, water from processing
or other sources which produces an unpolluted effluent satisfactory
for direct discharge into the storm drains or surface waterways. However,
if the director determines that no reasonable alternative method of
disposal other than discharge into the sewerage system of such waters
is available, the director may permit discharge into the sewerage
system of such waste if a contract is entered into between such person
and the city providing for payment by such person of additional processing
and facilities expansion costs, if any.
(Prior code § 2-15.40.04; Ord. 1082 § 2, 1983)
As deemed necessary by the director, a user shall provide facilities
for storage of peak flows to prevent flows beyond the capacity of
the sewerage system or the user's allocation of capacity.
(Prior code § 2-15.40.05; Ord. 1082 § 2, 1983)
No person shall discharge or cause to be discharged into the
sewerage system any of the following:
A. Any
liquid or vapor having a temperature higher than 150 degrees Fahrenheit;
B. Any
water or wastes which contain more than 200 milligrams per liter of
fat, oil or grease that is soluble by the freon extraction process;

(Prior code § 2-15.40.07; Ord. 1082 § 2, 1983; Ord.
1896 § 1, 2003)
A. General
Prohibition—Exceptions. No person shall discharge, or cause
to be discharged, any radioactive wastes into the sewerage system,
except where:
1. The
waste is discharged in strict conformance with current radiation control
regulations and federal regulations and recommendations for safe disposal
of such wastes;
2. The
discharging of such radioactive wastes will not cause injury to personnel
or damage to the sewerage system, irrespective of the provisions of
subsection (A)(1) of this section; and
3. A
wastewater discharge permit has been issued pursuant to this chapter.
B. Reports—Accidental
Spills. Any person permitted to discharge a radioactive waste into
the sewerage system in accordance with this section shall submit to
the director such reports as the director may deem necessary. In the
event of any accidental spill of any radioactive material into the
sewerage system, the person responsible shall:
1. Immediately
notify the city and the district; and
2. Render
such technical or other assistance to the city and the district as
may be within such person's power in order to prevent the sewerage
system from becoming contaminated with radioactivity.
(Prior code § 2-15.40.08; Ord. 1082 § 2, 1983)
No septic tank, holding tank, cesspool or chemical toilet waste
shall be discharged into the sewerage system at any points other than
those designated by the director. The director may grant a special
permit for such discharges; provided, that only waste material meeting
the requirements of this chapter shall be discharged. A fee for such
discharge shall be made as determined by the director.
(Prior code § 2-15.40.09; Ord. 1082 § 2, 1983)
Garbage shall be admitted to the sewerage system only if first
passed through a mechanically operated grinder. Garbage which increases
operation costs or decreases the treatment plant's effectiveness,
such as: (a) commercial garbage, (b) disposal of wastes from establishments
such as, but not limited to, restaurants, markets, hospitals, or nursing
homes, or (c) food processing wastes, shall be permitted only when
a special permit has been issued by the director providing for payment
of additional costs incurred as a result of said discharges.
(Prior code § 2-15.40.10; Ord. 1082 § 2, 1983)
In addition to the limitations upon the characteristics or quantity
of wastewater discharged, caused to be discharged or permitted to
be discharged into the sewerage system pursuant to this chapter, the
director may, in connection with the issuance of permits pursuant
to the provisions of this chapter, establish additional specific limitations
on wastewater discharges upon a finding by the director that:
A. The
limitations set forth in this chapter may not be sufficient to protect
the operation of the city's sewerage system, district treatment
facilities, or any portion thereof, or the waste or wastewater proposed
to be discharged otherwise constitutes a hazard to, or unreasonable
burden upon, such operation; or
B. The
limitations expressly set forth in this chapter may not be sufficient
to enable the operation of the sewerage system or district treatment
facilities to comply with water quality standards or effluent limitations
specified in the NPDES permit or any other applicable permit.
(Prior code § 2-15.40.11; Ord. 1082 § 2, 1983)
No user shall increase the use of process water or in any way
attempt to dilute a discharge as a partial or complete substitute
for adequate pretreatment in order to achieve compliance with the
limitations contained in the federal standards, or in any other pollutant
specific limitation developed by the city, state or federal government.
(Prior code § 2-15.40.12; Ord. 1082 § 2, 1983)
Nothing contained in this chapter shall be construed as preventing
any special agreement between the city and any person whereby any
water or waste of unusual strength or character or composition may
be accepted by the city for treatment. Such agreements may be allowed,
and, in the event that any such special agreement or arrangement shall
involve additional or extraordinary expense to the city or district,
such individual shall be required to reimburse the city therefor,
and to post with the city such bond or other guarantee as shall be
acceptable to the city to protect the city against any damage which
may be caused thereby.
(Prior code § 2-15.40.13; Ord. 1082 § 2, 1983)
Upon the promulgation of the federal categorical pretreatment
standards ("federal standards") or any new standards by
the district for a particular industrial subcategory, the federal
standards or the new district standards, if more stringent than limitations
imposed under this chapter for sources in any applicable subcategory,
shall immediately supersede the limitations imposed under this chapter.
(Prior code § 2-15.40.14; Ord. 1082 § 2, 1983)
All measurements, tests and analyses of the characteristics
of water and wastes shall be determined according to the standard
methods.
(Prior code § 2-15.40.15; Ord. 1082 § 2, 1983)
The director may require any user to install, prior to discharging
into the sewerage system and at such user's expense, pretreatment
or screening of such user's sewage, or such other measures as
may be necessary to reduce objectionable characteristics or constituents
so that the discharged sewage conforms with the requirements set forth
in this chapter. All plans and specifications relating to such pretreatment
or screening shall be reviewed by the director prior to construction
thereof. Approval of plans by the director shall not constitute a
guarantee of pretreatment performance. All such plans and specifications
shall be drawn by a registered professional engineer.
(Prior code § 2-15.40.16; Ord. 1082 § 2, 1983)
A. The
director may require any user to install and operate, at the user's
expense, monitoring facilities to allow inspection, sampling and flow
measurement in the side sewer or internal drainage systems. In the
event monitoring facilities are not available on any premises, the
city may monitor the sewage flow at the nearest manholes in the public
trunk sewer upstream and downstream of the service lateral serving
the user's premises and impute any difference therein to the
user's sewage.
B. Monitoring
facilities shall be situated on the user's premises, but the
director may allow, when such location would be impractical or cause
undue hardship on the user, the facility to be constructed within
the public street or sidewalk area in the service lateral, provided
that the same is located in such a manner that it will not be obstructed
by landscaping or parked vehicles.
C. There
shall be ample room in or near such monitoring facility to allow accurate
sampling and composting of samples for analysis. If the monitoring
facility is inside the user's fence, accommodations shall be
made to allow access to the same by city personnel, such as a gate
secured with a city lock.
D. Monitoring
facilities shall be provided in accordance with city design standards
and specifications whether constructed on public or private property.
E. Monitoring
facilities shall be maintained at all times in a safe and proper operating
condition at the full expense of the user.
F. Monitoring
facilities not installed upon initial construction of a project shall
be constructed and completed within 90 days following written notification
by the director that such facilities are required. The director may
grant a time extension upon a finding of good cause.
(Prior code § 2-15.40.17; Ord. 1082 § 2, 1983)
The director is authorized to inspect the premises of any user
at all reasonable times in order to ascertain whether the provisions
of this chapter or the provisions of any permit issued pursuant to
this chapter are being complied with. Owners or occupants of premises
where wastewater is created, held or discharged shall allow ready
access at all reasonable times to all parts of the premises for the
purposes of inspection, sampling, monitoring, records examinations,
or performing any or all of the duties reasonably necessary or appropriate
in carrying out or enforcing the provisions of this chapter or any
permit issued pursuant to this chapter. The director shall further
have the right to install and use on the user's premises such
devices as are reasonably necessary or appropriate to conduct sampling,
metering, or monitoring operations or any other of the aforesaid duties.
In the event a user has established security measures requiring identification
and clearance prior to entry onto such user's premises, the
user shall furnish and provide identification or clearance to the
director so as to permit ready access by the director to the premises
for the purposes described in this section.
(Prior code § 2-15.40.18; Ord. 1082 § 2, 1983)
A. Upon
determination by the director that such information is necessary or
appropriate for the director to reasonably carry out the provisions
of this chapter, the director may require that any person discharging,
causing to be discharged, permitting to be discharged, or proposing
to discharge wastewater into the sewerage system file a periodic discharge
report, the cost of which shall be borne by such person.
B. Discharge
reports shall include the following:
1. Information
relating to the nature of manufacturing, fabricating, or other processes
conducted by the user;
2. Statements
of the amount of fresh or nonwastewater volumes, wastewater volumes,
rates of flow, mass emission rates, production quantities, hours of
operation and number and classification of employees; or
3. Other
information relating to the generation of waste, including wastewater
constituents and characteristics of the pertinent wastewater discharge
as required by the director.
C. The
director may require that discharge reports include the chemical constituents
and quantity of liquid, gaseous, or solid materials stored on the
premises relating to such discharge, even though such materials are
not normally discharged into the sewerage system.
D. Discharge
reports shall be in addition to self-monitoring reports, information
furnished in connection with wastewater discharge permits, or other
permits authorized under this chapter. The reports authorized and
required under this section shall be filed with the director periodically
and/or at such other times as the director may reasonably require.
(Prior code § 2-15.40.19; Ord. 1082 § 2, 1983)
