[Ord. 1073, 11/8/2007, § 3.1]
Users shall provide wastewater treatment as necessary to comply with this Part and shall achieve compliance with all categorical pretreatment standards, local limits, and the prohibitions set out in §
18-405 of this Part within the time limitations specified by EPA, the state, or the City, 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 City for review, and shall be acceptable to the City 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 Part. The issuance of any permit by the City for pretreatment facilities pursuant to this Part does not constitute an approval of the design of any such pretreatment system. The user remains responsible for the design, construction, operation and maintenance of an acceptable pretreatment facility. The City shall have no responsibility or liability to any user whose system fails for any reason whatsoever to produce a discharge acceptable to the City.
[Ord. 1073, 11/8/2007, § 3.2]
1. Whenever deemed necessary and with reasonable justification, the
City 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 such
other conditions as may be necessary to protect the POTW and determine
the user's compliance with the requirements of this Part.
2. Grease, oil, and sand interceptors shall be provided when 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 City 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. Maintenance records shall
be made available to the City upon request.
3. Users with the potential to discharge flammable substances may be
required to install and maintain an approved combustible gas detection
meter.
[Ord. 1073, 11/8/2007, § 3.3]
1. At least once every two years, the City shall evaluate whether each
significant industrial user needs an accidental discharge/slug control
plan. The City may require any user to develop, submit for approval,
and implement such a plan. Alternatively, the City 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 that have the reasonable potential
to discharge to the POTW.
C. Procedures for immediately notifying the City of any accidental or slug discharge, as required by §
18-439 of this Part.
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 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.
[Ord. 1073, 11/8/2007, § 3.4]
Prior to installation of a zero discharge pretreatment system,
the user must submit a zero discharge pretreatment system design plan
for City acceptance. In order to obtain City acceptance, the user
must demonstrate that he or she will provide full pretreatment of
all wastewater and will cease to discharge process wastewater to the
facilities by an effective date prescribed by the City and the user
must obtain a zero discharge permit from the City.
