Users shall provide wastewater treatment as necessary to comply with this article and shall achieve compliance with all categorical pretreatment standards, local limits, and the prohibitions set out in section
13.08.031 of this article within the time limitations specified by the EPA, the state, the control authority, or the DCO, 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 DCO for review, and shall be acceptable to the DCO 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.
(2005 Code, sec. 13.4.120)
(a) Whenever deemed necessary, the DCO 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 DCO 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 DCO, 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 a type and capacity approved
by the DCO 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 DCO.
(2005 Code, sec. 13.4.121)
At least once every two (2) years, the DCO shall evaluate whether
each permitted significant industrial user needs an accidental discharge/slug
control plan. The DCO 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 DCO and control authority of any accidental or slug discharge, as required by section
13.08.186 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.
(2005 Code, sec. 13.4.122)
(a) Septage waste may be introduced into the POTW only at locations designated
by the DCO and control authority, and at such times as are established
by the DCO and control authority. Such waste shall not violate division
2 of this article or any other requirements established by the city.
The DCO 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.
