Users shall provide wastewater treatment as necessary to comply with this ordinance and shall achieve compliance with all categorical pretreatment standards, local limits, and the prohibitions set out in section
86-101 of this ordinance within the time limitations specified by EPA, the state, the control authority, or the director of public works, whichever is more stringent. Any facilities necessary for compliance shall be provided, operated, and maintained at the user’s expense. Detailed plans describing such facilities and operating procedures shall be submitted to the director of public works for review, and shall be acceptable to the director of public works 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 article.
(Ordinance 1574, § 1, 2-11-03)
(a) Whenever
deemed necessary, the director of public works may require users to
restrict their discharge during peak flow periods, designate that
certain wastewater be discharged only into specific sewers, relocate
and/or consolidate points of discharge, separate sewage wastestreams
from industrial wastestreams, and require such other conditions as
may be necessary to protect the POTW and determine the user’s
compliance with the requirements of this article.
(b) The
director of public works may require any person discharging into the
POTW to install and maintain, on their property and at their expense,
a suitable storage and flow-control facility to ensure equalization
of flow. A wastewater discharge permit may be issued solely for flow
equalization.
(c) Grease,
oil, and sand interceptors shall be provided when, in the opinion
of the director of public works, they are necessary for the proper
handling of wastewater containing excessive amounts of grease and
oil, or sand; except that such interceptors shall not be required
for residential users. All interception units shall be of type and
capacity approved by the director of public works and shall be so
located to be easily accessible for cleaning and inspection. Such
interceptors shall be inspected, cleaned, and repaired regularly,
as needed, by the user at their expense.
(d) Users
with the potential to discharge flammable substances may be required
to install and maintain an approved combustible gas detection meter,
or other control device as deemed necessary by the director of public
works.
(Ordinance 1574, § 1, 2-11-03)
At least once every two years, the director of public works
shall evaluate whether each permitted significant industrial user
needs an accidental discharge/slug control plan. The director of public
works may require any user to develop, submit for approval, and implement
such a plan. An accidental discharge/slug control plan shall address,
at a minimum, the following:
(1) Description
of discharge practices, including nonroutine batch discharges;
(2) Description
of stored chemicals;
(3) Procedures for immediately notifying the director of public works and control authority of any accidental or slug discharge, as required by section
86-131 of this article; and
(4) 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,
building of containment structures or equipment, measures for containing
toxic organic pollutants, including solvents, and/or measures and
equipment for emergency response.
(Ordinance 1574, § 1, 2-11-03)
(a) Septage
waste may be introduced into the POTW only at locations designated
by the director of public works and control authority, and at such
times as are established by the director of public works and control
authority. Such waste shall not violate Division 2 of this article
or any other requirements established by the city. The director of
public works and/or control authority may require septic tank waste
haulers to obtain wastewater discharge permits.
(b) Septage
waste haulers must provide a waste-tracking form for every load. This
form shall include, at a minimum, the name and address of the waste
hauler, permit number, truck identification, names and addresses of
sources of waste, and volume and characteristics of waste. The form
shall identify the type of generator, known or suspected waste constituents,
and whether any wastes are RCRA hazardous wastes.
