[Amended 11-18-2013 by Ord. No. 1563]
Users shall provide wastewater treatment as necessary to comply with this chapter and shall achieve compliance with all categorical pretreatment standards, local limits, and the prohibitions set out in § 553-18 of this chapter within the time limitations specified by the EPA, the state, or the Director, whichever is more stringent. Any facilities necessary for compliance shall be provided, operated, and maintained at the user's expense. Detailed written plans describing such facilities and operating procedures shall be submitted to the Director for review and acceptance 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 Director under the provisions of this chapter.
A.
Whenever he deems it necessary, the Director 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 waste streams
from industrial waste streams, and impose such other conditions as
may be necessary to protect the POTW and determine the user's compliance
with the requirements of this chapter.
B.
The Director may require any persons 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, they are necessary for the proper handling
of wastewater containing excessive amounts of grease and oil or sand,
except that such interceptors may not be required for residential
users. All interception units shall be of type and capacity approved
in writing by the Director and shall be so located as to be easily
accessible for cleaning and inspection. Such interceptors shall be
inspected, cleaned, and repaired regularly, as needed, by the users
at their expense.
[Amended 11-18-2013 by Ord. No. 1563]
At least once every two years, the Director shall evaluate whether
each significant industrial user needs an accidental discharge/slug
control plan. The Director may require any user to develop, submit
for approval, and implement such a plan. Alternatively, the Director
may develop such a plan for any user. An accidental discharge/slug
control plan shall address, at a minimum, the following:
A.
Description of discharge practices, including nonroutine batch discharges;
B.
Description of stored chemicals;
C.
Procedures for immediately notifying the Director of any accidental or slug discharge as required by § 553-47 of this chapter; and
D.
Procedures to prevent adverse impact from any accidental or slug
discharge. Such procedures shall 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.
Septic tank waste, generated only in the City, may be introduced into the POTW only at locations designated in writing by the Director and at such times as are established in writing by the Director. The introduction of such wastes shall not violate Article III of this chapter or any other requirements established by the City. The Director may require septic waste haulers to obtain wastewater discharge permits.
