[Ord. 486, 3/21/2002, § 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 §
18-305 of this Part within the time limitations specified by EPA, the state, or MACM, 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 MACM for review, and shall be acceptable to MACM 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 MACM under the provisions of this Part.
[Ord. 486, 3/21/2002, § 3.2]
1. Whenever deemed necessary, MACM may require user's to restrict their
discharge 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 such other conditions as may be necessary to protect
the POTW and determine the user's compliance with the requirements
of this Part.
2. MACM 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.
3. Grease, oil, and sand interceptors shall be provided when, in the
opinion of MACM, 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 MACM
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.
4. Users with the potential to discharge flammable substances may be
required to install and maintain an approved combustible gas detection
meter.
[Ord. 486, 3/21/2002, § 3.3]
1. At least once every two years, MACM shall evaluate whether each significant
industrial user needs an accidental discharge/slug control plan. MACM
may require any user to develop, submit for approval, and implement
such a plan. Alternatively, MACM 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 MACM of any accidental or slug discharge, as required by §
18-335 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. 486, 3/21/2002, § 3.4]
1. Septic tank waste or municipal digested sewage sludge may be introduced into the POTW only at locations designated by MACM, and at such times as are established by MACM. Such waste shall not violate §
18-305 of this Part or any other requirements established by MACM. MACM may require waste haulers to obtain wastewater discharge permits.
2. MACM shall require haulers of industrial waste to obtain wastewater
discharge permits. MACM may require generators of hauled industrial
waste to obtain wastewater discharge permits. MACM also may Prohibit
the disposal of hauled industrial waste. The discharge of hauled industrial
waste is subject to all other requirements of this Part.
3. Industrial waste haulers may discharge loads only at locations designated
by MACM. No load may be discharged without prior consent of MACM.
MACM may collect samples of each hauled load to ensure compliance
with applicable standards. MACM may require the industrial waste hauler
to provide a waste analysis of any load prior to discharge.
4. Industrial waste haulers must provide a waste-tracking form for every
load. This form shall include, at a minimum, the name and address
of the industrial 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 industry, known or suspected
waste constituents, and whether any wastes are RCRA hazardous wastes.
