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.
NEW SOURCE
1.
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) of the Act which will be applicable
to such source if such standards are thereafter promulgated in accordance
with that Section, provided that:
a.
The building, structure, facility or installation is constructed
at a site where no other source is located;
b.
The building, structure, facility or installation totally replaces
the process or production equipment that causes the discharge of pollutants
at an existing source; or
c.
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.
2.
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 Subparagraphs (1)(b) or (c) above but otherwise
alters, replaces or adds to existing process or production equipment.
3.
Construction of a new source as defined under this Subparagraph
has commenced if the owner or operator has:
a.
Begun or caused to begin as part of a continuous on-site construction
program:
(1)
Any placement, assembly or installation of facilities or equipment;
or
(2)
Significant site preparation work 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
b.
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 Subparagraph.
NORMAL DOMESTIC WASTEWATER
Any combination of waters from water closets, urinals, lavatories,
sinks, bathtubs, showers, household laundries, household garbage grinders,
bars, soda fountains, cuspidors, refrigerators, dryers, drinking fountains
and all other liquid and water-carried wastes, except industrial wastes
and cooling water, having a BOD concentration of not more than three
hundred (300) milligrams per liter and a suspended solids concentration
of not more than three hundred fifty (350) milligrams per liter.
PASS THROUGH
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).
POLLUTION
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.
POTW
Means 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.
PRETREATMENT
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).
PRETREATMENT REQUIREMENTS
Any substantive or procedural requirement related to pretreatment,
other than a national pretreatment standard, imposed on an industrial
user.
PRIVATE SEWER COLLECTION SYSTEM

stormwater, rainwater, downspouts, foundation drains runoffs, etc.
Stormwater, rainwater, downspouts, foundation drain runoffs, etc.,
are prohibited to discharge into the sanitary sewer system.
SIGNIFICANT INDUSTRIAL USER
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 wastestream 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.
SIGNIFICANT NON-COMPLIANCE
Any one (1) of the following:
1.
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;
2.
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-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);

any required reports, including baseline monitoring reports, ninety-day
compliance reports, periodic self-monitoring reports and reports on
compliance schedules;
7.
Failure to accurately report non-compliance; or
8.
Any other violation(s) which the City determines will adversely
affect the operation or implementation of the local pretreatment program.
