of 350 mg/l or a loading of fats, oils or greases of animal or vegetable
origin or oil and grease or other petroleum or mineral oil products

from any source, including agriculture, forestry, fishing, mining,
manufacturing, transportation, communication, electrical, gas and
sanitary services and other industrial services discharging into the
POTW any industrial waste or discharging into the POTW any waste other
than domestic sewage as defined in this section. This term may also
apply to any other source of pollutant which adversely affects the
POTW.
INDUSTRIAL WASTE
All water, water-carried solids, liquid and gas wastes resulting
from any industrial, manufacturing or food processing operation or
process or from the development of any natural resource or any mixture
of these fluids and domestic sewage or any mixture of these fluids
with any other water or with any other liquid.
INSTANTANEOUS MAXIMUM ALLOWABLE DISCHARGE LIMIT
The maximum concentration or loading of a pollutant allowed
to be discharged at any time, determined from the analysis of any
grab or composite sample collected, independent of the industrial
flow rate and the duration of the sampling event.
INTERFERENCE
A discharge that, alone or in conjunction with a discharge
or discharges from other sources, both:
(1)
Inhibits or disrupts the City's POTW, treatment
processes or operations or its sludge processes, use or disposal;
and
(2)
Which thus contributes to cause a violation
of any requirement of the City's MEPDES permit, including an increase
in the magnitude or duration of a violation, or of the prevention
of sludge use or disposal in compliance with statutory provisions
and regulations or permits issued under Section 405 of the Clean Water
Act, RCRA, the Clean Air Act, SWDA, the Toxic Substances Control Act, the Marine Protection, Research and Sanctuaries Act and

[Amended 6-9-2008 by Ord. No. 08-195]
MASS-BASED LIMITATIONS
Users implementing process changes, including best management
practices, may request permit discharge limitations be based on mass
limitations in lieu of concentration-based limitations. The intent
of mass-based limitations is to encourage and allow best management
practices, pollution prevention and/or water conservation measures
that may result in increased pollutant concentrations while not increasing
actual mass of pollutant discharged. Mass-based limitations shall
be calculated from current, pollutant-specific concentration and user
discharge flow. Mass-based limitations shall not exceed the previous
mass of specific pollutant discharged (prior to the implementation
of process changes or best management practices) based on the historic
performance of that user. Decisions on granting requests for mass-based
limitations will be based on user-specific information and current
operating conditions of the POTW and will be at the discretion of
the Director. Implementation of mass-based limitations shall not contravene
any requirements or limitations of federal or state law and/or regulations
implemented thereunder and may not waive applicable categorical pretreatment
standards.
[Added 6-9-2008 by Ord. No. 08-195]
MEDICAL WASTE
Isolation wastes, infectious agents, human blood and blood
products, pathological wastes, sharps, body parts, contaminated bedding,
surgical wastes, potentially contaminated laboratory wastes and dialysis
wastes.
MILLIGRAMS PER LITER
A weight to volume ratio. The figure appearing before the
symbol "mg/l" shall be the number of milligrams to be found in one
liter of the substance being tested. This figure can be transposed
to pounds per million gallons of water by multiplying said figure
by 8.34.
NATURAL OUTLET
Any outlet into a watercourse, pond, ditch, lake or other
body of surface water or groundwater.
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 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 of the
Act, provided that:
(a)
The building, structure, facility or installation
is constructed at a site at which no other source is located; or
(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 the sources are substantially independent, factors such as
the extent 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 Subsection
1(b) or
(c) of this definition above but otherwise alters, replaces or adds to existing process or production equipment.
(3)
Construction of a new source as defined under
this section has commenced if the owner or operator has:
(a)
Begun, or caused to begin, as part of a continuous
on-site construction program, any placement, assembly or installation
of facilities or equipment or significant site preparation work, including
clearing, excavation or removal of existing buildings, structures
or facilities which is 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 is intended to be
used in their 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.
NONCONTACT COOLING WATER
Water used for cooling which does not come into direct contact
with any raw material, intermediate product, waste product or finished
product.
NORMAL DOMESTIC SEWAGE
Sewage in which the average concentration of TSS does not
exceed 250 mg/l and in which the five-day BOD does not exceed 250
mg/l and fats, oils or greases of animal or vegetable origin or oil
and grease and other petroleum or mineral oil products do not exceed
100 mg/l.

use where water service is metered independently or that discharges
wastewater to the POTW.
