from time to time as deemed necessary by the City for the purpose
of being a control mechanism and used in issuance of Industrial Waste
Discharge Permits.
Any regulation containing pollutant discharge limits containing
pollutant discharge limits promulgated by the USEPA which applies
to industrial users. This term includes prohibitive discharge limits
established pursuant to 40 CFR 403.5.
Any building, structure, facility
or installation from which there is or may be a discharge of pollutants,
the construction of which commenced after the publication of the proposed
pretreatment standards under Section 307(c)[2] of the Act which will be applicable to such source if
such standards are thereafter promulgated in accordance with that
Section, provided that:
The building, structure, facility
or installation is constructed at a site where no other source is
located; or
The building, structure, facility
or installation totally replaces the process or production equipment
that causes the discharge of pollutants at an existing source; or
The production or wastewater generating
processes of the building, structure, facility or installation are
substantially independent of an existing source at the same site.
In determining whether these are substantially independent, factors
such as the extreme to which the new facility is integrated with the
existing plant, and the extent to which the new facility is engaged
in the same general type of activity as the existing source, should
be considered.
Construction on a site at which an existing source is located results in a modification rather than a new source if the construction does not create a new building, structure, facility or installation meeting the criteria of Subsection (1)(b) or (c) above but otherwise alters, replaces, or adds to existing process or production equipment.
Construction of a new source as defined
under this paragraph has commenced if the owner or operator has:
Begun, or caused to begin as part
of a continuous on-site construction program:
Any placement, assembly, or installation
of facilities or equipment; or

including clearing, excavation, or removal of existing buildings,
structures, or facilities which are necessary for the placement, assembly
or installation of new source facilities or equipment; or
Entered into a binding contractual
obligation for the purchase of facilities or equipment which are intended
to be used in its operation within a reasonable time. Options to purchase
or contracts which can be terminated or modified without substantial
loss, and contracts for feasibility, engineering, and design studies
do not constitute a contractual obligation under this Subsection.
A wastewater discharge which exits the POTW into waters of
the State in quantities or concentrations which, alone or in conjunction
with a discharge(s) from other sources, the City deems to have the
potential for, or causes, the POTW to violate any requirements of
the City's POTW NPDES Permit, including an increase in the magnitude
or duration of violation(s).
The presence of any foreign substance (organic, inorganic,
or biological) in water which tends to degrade its quality so as to
constitute a hazard or impair the usefulness of the water to a degree
which does not create an actual hazard to the public health which
does adversely and unreasonably affect such waters for domestic use.
Publicly owned treatment works and shall include all facilities
or devices that collect, transport and/or treat domestic, commercial
or industrial wastes and are owned and/or operated by the City, or
by sewage systems that convey wastewaters into and through the City
system and which have entered into agreement for transportation and
treatment of wastewater by the City.
The reduction of the amount of pollutants, the elimination
of pollutants or the alteration of the nature of pollutant properties
in wastewater prior to or in lieu of discharging or otherwise introducing
such pollutants into a POTW. The reduction or alteration may be obtained
by physical, chemical or biological processes, process changes or
by other means, except as prohibited by 40 CFR 403.6(d): Appropriate
pretreatment technology includes control equipment, such as equalization
tanks or facilities, for protection against surges or slug loadings
that might interfere with or otherwise be incompatible with the POTW.
However, where wastewater from a regulated process is mixed in an
equalization facility with unregulated wastewater or with wastewater
from another regulation process, the effluent from the equalization
facility must meet an adjusted pretreatment limit calculated in accordance
with 40 CFR 403.6(e).

consumption through pipes or other constructed conveyances, if such
system has at least fifteen (15) service connections or regularly
serves an average of at least twenty-five (25) individuals daily at
least sixty (60) days per calendar year. Such system includes any
collection, treatment, storage or distribution facilities used in
connection with such system.
The connection of the customer service line onto the downstream
end of the water meter.
Shall mean sanitary sewer; all sewage or wastes from a customer's
property or user, excluding stormwater, rainwater, downspouts, foundation
drains runoffs, etc. Stormwater, rainwater, downspouts, foundation
drain runoffs, etc., are prohibited to discharge into the sanitary
sewer system.
Any user which is subject to Categorical Pretreatment Standards
or any non-categorical user that discharges twenty-five thousand (25,000)
gallons per day or more processed wastewater, or that contributes
a processed waste stream which makes up to five percent (5%) or more
of the dry weather hydraulic or organic capacity of the POTW, or any
user that has a reasonable potential, in opinion of the City, for
adversely affecting the POTW's operation or for violating any pretreatment
standard or requirement.
Any one of the following:
Chronic violations of wastewater
discharge limits, defined herein as those in which sixty-six percent
(66%) or more of wastewater measurements taken during a six-month
period exceed the daily maximum limit or average limit for the same
pollutant parameter in any amount;
Technical Review Criteria (TRC) violations,
defined here as those in which thirty-three percent (33%) or more
of wastewater measurements taken for each pollutant parameter during
a six (6) month period equals or exceeds the product of the daily
maximum limit or the average limit multiplied by the applicable criteria
[1.4 for BOD, TSS, fats, oils and grease, and 1.2 for all other pollutants
except pH];
