of the discharge or proposed discharge.
Nothing in this section shall prevent the establishment and
application of specific pollutant discharge limits by the Commissioner
on any user or on any individual discharger where materials, substances,
waters, wastes or other pollutants discharged by the user or class
of user have the potential, singly or in combination with other discharges,
to result in pass through or interference in the operation of the
WWTP.
[Ord. No. 1226, § I, 6-23-2020]
Except where expressly authorized to do so by an applicable
pretreatment standard or requirement, no user shall increase the use
of process water or in any other way attempt to dilute a discharge
as a partial or complete substitute for adequate treatment to achieve
compliance with a pretreatment standard or requirement.
[Ord. No. 1226, § I, 6-23-2020]
If any wastewater or wastes are discharged, or are proposed to be discharged to the public sewers, which waters contain the substances or possess the characteristics in §§
19-20 through
19-22 of this article, and which, in judgment of the Commissioner reasonably appear to present an imminent endangerment to the health or welfare of persons, the Commissioner may, with informal notice to any discharger, demand an immediate cessation of, or prevent, said discharge. With notice of the discharger as elsewhere contained in this chapter, the Commissioner may halt or prevent any discharge to the public sewer which presents or may present an endangerment to the environment or which threatens to interfere with the operation of WWTP. In addition to rejecting the wastes, the Commissioner may:
(a) Require pretreatment to an acceptable condition for discharge to
the public sewers;
(b) Require control over the quantities and rates of discharged and/or
(c) Require payment to cover the added cost of handling and treating
the waste not covered by the existing user charge system.
If the Commissioner permits the pretreatment or equalization
of waste flows, the design and installation of the plants and equipment
shall be subject to the review and approval of the Commissioner and
subject to the requirements of all applicable codes, ordinances, laws
and pretreatment standards. Any and all costs associated with the
design, construction, operation and maintenance, and compliance with
the conditions of this chapter are borne by the user, including the
costs for City administration under this chapter.
Any discharger not in compliance with any categorical pretreatment
standard, local limit, or other limit imposed by state or federal
law shall submit to the Commissioner a compliance schedule meeting
the requirements of this chapter, and, in the case of noncompliance
with a categorical pretreatment standard, such schedule shall meet
the requirements of 40 CFR Part 403. Not later than 14 days following
each date in such schedule and the final date for compliance, the
discharger shall submit a progress report to the Commissioner indicating
whether or not an increment of progress or final compliance date was
met and, if not met, when compliance with that increment of progress
or final compliance is expected.
Within 90 days after a final date of compliance with any categorical
pretreatment standard, local limit, or limit imposed by state or federal
law, or, in the case of a new source industrial user, within 90 days
after commencement of discharge to the wastewater system, each industrial
user shall submit to the Commissioner a report of compliance with
the categorical pretreatment standard, local limit, or limit imposed
by state or federal law, said report meeting the requirements of 40
CFR Part 403.
[Ord. No. 1226, § I, 6-23-2020]
Grease, oil and sand interceptors shall be provided when, in
the opinion of the Commissioner, they are necessary for the proper
handling of liquid wastes containing grease in excessive amounts,
or any flammable wastes, sand or other harmful ingredients; except
that such interceptors shall not be required for private living quarters
or dwelling units. All interceptors shall be a type and capacity approved
by the Commissioner, and shall be located as to be readily and easily
accessible for cleaning and inspection.
[Ord. No. 1226, § I, 6-23-2020]
Where pretreatment or flow-equalizing facilities are provided
for any waters or wastes, they shall be maintained continuously in
satisfactory and effective operation by the owner at their expense.
Detailed plans describing such facilities and operating procedures
shall be submitted to the Commissioner for review, and shall be acceptable
to the Commissioner 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.
[Ord. No. 1226, § I, 6-23-2020]
The Commissioner shall evaluate whether each SIU needs an accidental
discharge/slug discharge control plan or other action to control slug
discharges. The Commissioner may require any user to develop, submit
for approval, and implement such a plan or take such other action
that may be necessary to control slug discharges. Alternatively, the
Commissioner may develop such a plan for any user. An accidental discharge/slug
discharge control plan shall address, at a minimum, the following:
(a) Description of discharge practices, including non-routine batch discharges;
(b) Description of stored chemicals;
(c) Procedures for immediately notifying the Commissioner of any accidental
or slug discharge, as required by this chapter; and
(d) 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 runoff, worker
training, building of containment structures or equipment, measures
for containing toxic organic pollutants, including solvents, and/or
measures and equipment for emergency response.
[Ord. No. 1226, § I, 6-23-2020]
Domestic septage may be introduced into the wastewater system only at locations designated by the Commissioner, and at such times as are established by the Commissioner. Such waste shall not violate Section
19-21 of this chapter or any other requirements established by the City. The Commissioner requires domestic septage haulers to obtain annual permits through the City. No load may be discharged without prior consent of the Commissioner. The Commissioner and other duly authorized employees of the City may collect samples of each hauled load to ensure compliance with applicable standards.
[Ord. No. 1226, § I, 6-23-2020]
When required by the Commissioner, the owner of any property
serviced by a building sewer carrying industrial wastes shall install
a suitable control manhole or sampling location together with such
necessary meters, and other appurtenances in the building sewer to
facilitate observation, sampling and measurement of the wastes. Such
manhole or sampling location, when required, shall be accessible and
safely located and shall be constructed in accordance with plans approved
by the Commissioner. The manhole shall be installed by the owner at
their expense and shall be maintained by them so as to be safe and
accessible at all times.
[Ord. No. 1226, § I, 6-23-2020]
(a) All measurements, tests, and analyses of the characteristics of wastewater
and wastes to which reference is made in this chapter shall be determined
in accordance with the test methods and procedures as established
in 40 CFR Part 136 and shall be determined at the control manhole
provided, or upon samples taken at the control manhole or at such
other sampling location or locations as may be specified by the Commissioner.
In the event that no special manhole or sampling location has been
provided, the control manhole or sampling locations shall be as determined
by the Commissioner.
(b) Sampling events shall be carried out by customarily accepted methods
to reflect the effect of constituents upon the wastewater works and
to determine the existence of hazards to life, limb and property.
The sampling and analysis will be consistent with the applicable permit
limits and the facility discharge method. The Commissioner may modify
sampling and analytical methods in order to determine compliance with
this chapter.
(c) All industries discharging into a public sewer shall perform such
monitoring of their discharges as the Commissioner and/or other duly
authorized employees of the City may reasonably require, including
installation, use, and maintenance of monitoring equipment, keeping
records and reporting the results of such monitoring to the Commissioner.
Such records shall be made available upon request by the Commissioner
to other agencies having jurisdiction over discharges to the receiving
waters. Industrial users shall maintain records of any monitoring
activities and sampling results for a period of three years or during
the course of any unresolved litigation regarding the industrial user
to which the such records may be pertinent, whichever shall be the
greater, and shall make such records available for inspection and
copying by the Commissioner or their duly authorized representative
on demand.
(d) Any industrial user subject to a pretreatment standard shall provide
to the Commissioner, at a minimum of once every six months or at such
greater frequency as the Commissioner may require, a report of the
nature, concentration and flow of pollutants in the discharge to the
sewer from the establishment. Such report shall be signed by a responsible
corporate officer or by a general partner or proprietor of the industrial
user or by their duly authorized representative and submitted on a
form and in such detail and extent as the Commissioner may require
pursuant to the performance of their duties under the provisions of
this chapter.
