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 § 11.10 of this chapter within the time limitations specified by EPA, the State, or the Superintendent, 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 Superintendent for review, and shall be acceptable to the Superintendent 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 chapter.
A.
The City shall require to be provided and operated at the industrial
user's own expense monitoring facilities to allow inspection,
sampling, and flow measurement of the building sewer and/or internal
drainage systems. The monitoring facility normally should be situated
on the industrial user's premises, but the City may, when such
a location would be impractical or cause undue hardship on the industrial
user, allow the facility to be constructed in the public street or
sidewalk area, and located so that it will not be obstructed by landscaping
or parked vehicles.
B.
There shall be ample room in or near such sampling manhole or facility
to allow accurate sampling and preparation of samples for analysis.
The facility, sampling, and measuring equipment shall be maintained
at all times in a safe and proper operating condition at the expenses
of the industrial user.
C.
Whether constructed on public or private property, the sampling and
monitoring facilities shall be provided in accordance with the City's
requirements and all applicable local construction standards and specifications.
Construction shall be completed within 90 days following written notification
that the City requires a sampling manhole unless the City otherwise
grants a time extension.
D.
Monitoring facilities shall be constructed and maintained in accordance
with the specifications for a gauging manhole as detailed in the most
current edition of "Standard Specifications for Sewer and Water Construction
in Wisconsin."
E.
When more than one industrial user can discharge into a common sewer,
the Superintendent may require installation of separate monitoring
equipment for each industrial user. When there is a significant difference
in wastewater constituents and characteristics produced by different
operations of a single industrial user, the Superintendent may require
that separate monitoring facilities be installed for each separate
discharge.
A.
Whenever deemed necessary, the Superintendent 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 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 Superintendent 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 Superintendent, 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 Superintendent 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.
At least once, the Superintendent shall evaluate whether each
significant industrial user needs an accidental discharge/slug control
plan. The Superintendent may require any user to develop, submit for
approval, and implement such a plan. Alternatively, the Superintendent
may develop such a plan for any user. The Superintendent shall review
the need for said plan, or other actions, as part of the ongoing oversight
of the 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 Superintendent of any accidental or slug discharge, as required by § 11.32F of this chapter; and
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.
A.
Inititial report. At least 180 days before the commencement of discharge,
a new centralized waste treater shall provide the Superintendent with
the following information:
(1)
Name, location, mailing address, and names of the owner and operator;
(2)
A description of the treatment equipment and processes, a schematic
diagram and a discussion of performance capabilities;
(3)
The types of waste the centralized waste treater intends to treat,
identified by industrial category and manufacturing process, and estimated
volumes for each type of waste;
(4)
A description of the waste acceptance procedures developed according to Subsection C of this section;
(6)
Any other information required by the Superintendent.
B.
New wastestream report. At least 60 days before accepting wastes from an industrial category or manufacturing process not included in the report required by Subsection A of this section, a centralized waste treater shall submit to the Superintendent the following information for the new type of waste:
C.
Waste acceptance procedures. Each centralized waste treater shall
implement waste acceptance procedures sufficient to ensure that wastes
accepted for treatment are within the centralized waste treater's
treatment capabilities and have no characteristics that could reasonably
be expected to prevent compliance with the applicable pretreatment
standards and requirements. These acceptance procedures shall include
sampling and analysis, treatability studies and any other procedures
necessary to identify the source and character of the waste.
D.
Effluent monitoring. Sampling and analysis of the centralized waste treater effluent shall be sufficient to assess consistent compliance with the applicable pretreatment standards and requirements. Samples shall be analyzed according to § 11.32J of this chapter.
E.
Periodic compliance reports. On a schedule established by the Superintendent,
each centralized waste treater shall provide to the Superintendent
the following information for all wastes treated since the previous
report:
(1)
The name and address of the generator of each waste received by the
centralized waste treater;
(2)
The volume and arrival date of each wastewater shipment to the centralized
waste treater, and the name and address of the transporter;
(3)
The applicable pretreatment standards, including the generator's
production data, if production based standards apply;
(4)
Effluent volume and effluent sampling and analysis results; and
(5)
Any other information requested by the Superintendent.
F.
Combined waste streams.
(2)
Alternative limits.
(a)
The centralized waste treater shall comply with alternative
discharge limits determined by the Superintendent when:
[1]
The Superintendent determines that the calculation of alternative discharge limits according to § 11.11C are not practical; and
[2]
The DNR has approved the Superintendent's determination and alternative limits, which have been developed according to § 11.24F(2)(b) as follows.
(b)
Alternative limits developed according to this subsection shall
assure treatment equivalent to that prescribed in the categorical
standards, which apply to the contributing waste streams. Alternative
limits shall be based on the most stringent categorical limit for
each pollutant or the best available treatment technologies for the
contributing waste streams.
(3)
Neither dilution nor mixing may be used in lieu of treatment to achieve
compliance with applicable limitations, the Superintendent shall require
segregated treatment of waste streams.
