20.
Any discharge or effluent which violates the limitations imposed
by a wastewater discharge permit issued under the provisions of this
Chapter, or categorical standard, including equivalent concentration
limits based on a mass- or production-based categorical standard and
concentration limits derived in accordance with the combined wastestream
formula.
[Ord. No. 2206 §§1 —
2, 6-5-2000]
A.
When
necessary to protect or to prevent adverse effects on the POTW, its
treatment processes, receiving stream, sludge treatment or disposal
processes, to provide for worker health and safety, to impose categorical
standards, or to address similar concerns of other jurisdictions providing
sewer service to the City, the Director may:
1.
Impose mass limitations in addition to or in place of concentration
limitations provided for in this Chapter or in any applicable categorical
pretreatment standards;
2.
Establish more stringent standards or requirements for discharge
to the POTW in wastewater discharge permits;
3.
Establish limits on the effluent from specific industrial processes
or pretreatment systems in wastewater discharge permits;
4.
Issue wastewater discharge permits to industrial users setting out
special requirements for discharge to the POTW. In no case shall a
permit waive compliance with a categorical pretreatment standard or
allow any discharge which could cause pass through or interference,
except that the Director may establish a reasonable time frame for
compliance with this Chapter;
5.
Require treatment to reduce the BOD, suspended solids, and/or oil
and grease concentrations in a discharge to levels more closely approaching
those of normal sewage; and/or
[Ord. No. 2206 §§1 —
2, 6-5-2000]
No industrial user shall ever increase the use of process water,
or in any way attempt to dilute a discharge, as a partial or complete
substitute for adequate treatment to achieve compliance with a pretreatment
standard unless expressly authorized by an applicable pretreatment
standard.
[Ord. No. 2206 §§1 —
2, 6-5-2000]
The Director may require any industrial user to undertake a
compatibility study for waste proposed for discharge to the POTW to
determine whether the waste may be accepted by the POTW.
[Ord. No. 2206 §§1 —
2, 6-5-2000]
Hauled wastes, including septic tank sludge, contents of cesspools
and privy vaults, and other non-hazardous wastes, shall not be introduced
or accepted into the City's sewers other than through a facility with
a wastewater discharge permit.
[Ord. No. 2206 §§1 —
2, 6-5-2000]
A.
The
Director may require reasonable safeguards to prevent discharge or
leakage of any material stored in areas served by, or draining into,
the POTW which could create a fire or an explosion hazard in the POTW
or in any other way have a deleterious effect upon the POTW's facilities
or treatment processes, or constitute a hazard to human beings or
animals or the receiving stream.
B.
The
Director may require any industrial user to develop and implement
an accidental/slug discharge control plan. This plan shall include
at least the following:
1.
Description of discharge practices, including non-routine batch discharges;
2.
Description and location of stored chemicals;
4.
Procedures for permanently posting a notice in a conspicuous place in a common area of the industrial user's premises advising employees whom to call in the event of a discharge described in Subsection (A) of this Section. Employers shall ensure that all employees who may cause or suffer such a discharge to occur are advised of the emergency notification procedure; and
5.
Procedures to prevent adverse impact from any accidental or slug
discharge. Such procedures include, but are not limited to, inspection
and maintenance of storage areas, handling and transfer of materials,
loading and unloading operations, control of plant site runoff, worker
training, measures for containing materials, and/or measures and equipment
for emergency responses.
[Ord. No. 2206 §§1 —
2, 6-5-2000]
The Director may require the owner of any property occupied
by an industrial user to install and maintain at his own expense suitable
monitoring facilities to facilitate the City's and the industrial
user's observation, sampling and measurement of the discharge of the
building sewer and/or internal drainage systems and/or effluent from
specific processes.
Such facilities shall be easily accessible and safely located
and shall have ample room in or near said facilities to allow accurate
collection and preparation of samples for analysis. Such facilities
shall be constructed in accordance with plans approved by the Director
and shall be located so as to permit the gauging of flow and the collection
of samples truly representing the effluent from regulated processes
or the discharge from the property. The facilities and the sampling
and measuring equipment shall be maintained at all times in a safe
and proper condition at the expense of the industrial user.
