collected during a calendar day or twenty-four-hour-period.
DAILY MAXIMUM LIMIT
The maximum allowable discharge limit of a pollutant during
a calendar day or twenty-four-hour-period. Where daily maximum limits
are expressed in units of mass, the daily discharge is the total mass
discharged over the course of the day. Where daily maximum limits
are expressed in terms of a concentration, the daily discharge is
the arithmetic average measurement of the pollutant concentration
derived from all measurements taken that day.
ENVIRONMENTAL PROTECTION AGENCY or EPA
The U.S. Environmental Protection Agency or, where appropriate,
the Regional Water Management Division Director, or other duly authorized
official of said agency.
EXISTING SOURCE
Any source of discharge, the construction or operation of
which commenced prior to the publication by EPA of proposed categorical
pretreatment standards, which will be applicable to such source if
the standard is thereafter promulgated in accordance with Section
307 of the Act.
GRAB SAMPLE
A sample which is taken from a waste stream without regard
to the flow in the waste stream and over a period of time not to exceed
15 minutes.
INDIRECT DISCHARGE or DISCHARGE

source regulated under Section 307(b), (c), or (d) of the Act.
INSTANTANEOUS MAXIMUM ALLOWABLE DISCHARGE LIMIT
The maximum concentration of a pollutant allowed to be discharged
at any time, determined from the analysis of any discrete or composited
sample collected, independent of the industrial flow rate and the
duration of the sampling event.
INTERFERENCE
A discharge, which alone or in conjunction with a discharge
or discharges from other sources, inhibits or disrupts the POTW, its
treatment processes or operations or its sludge processes, use or
disposal; and therefore, is a cause of a violation of the City's NPDES
permit (including an increase in the magnitude or duration of a violation)
or of the prevention of sewage sludge use or disposal in compliance
with any of the following statutory/regulatory provisions or permits
issued thereunder, or any more stringent state or local regulations:
Section 405 of the Act; the Solid Waste Disposal Act, including Title
II, commonly referred to as the "Resource Conservation and Recovery
Act" (RCRA); any state regulations contained in any state sludge management
plan prepared pursuant to Subtitle D of the Solid Waste Disposal Act;
the Clean Air Act; the Toxic Substances Control Act; and the Marine Protection, Research, and Sanctuaries Act.
LOCAL LIMIT

upon industrial or commercial facilities to implement the general
and specific discharge prohibitions listed in 40 CFR 403.5(a)(1) and
(b).
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.
MONTHLY AVERAGE
The sum of all daily discharges measured during a calendar
month divided by the number of daily discharges measured during that
month.
MONTHLY AVERAGE LIMIT
The highest allowable average of daily discharges over a
calendar month, calculated as the sum of all daily discharges measured
during a calendar month divided by the number of daily discharges
measured during that month.
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, provided that:
(a)
The building, structure, facility, or installation is constructed
at a site at which no other source is located;
(b)
The building, structure, facility, or installation totally replaced
the process or production equipment that causes the discharge of pollutants
at an existing source; or
(c)
The production of 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 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) above but otherwise alters, replaces, or adds to existing process or production equipment.
(3)
Construction of a new source as defined under this definition
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
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 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 definition.
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.
PASS THROUGH
A discharge which exits the POTW into waters of the United
States in quantities or concentrations which, alone or in conjunction
with a discharge or discharges from other sources, is a cause of a
violation of any requirement of the City's NPDES permit, including
an increase in the magnitude or duration of a violation.
PERSON
Any individual, partnership, copartnership, firm, company,
corporation, association, joint stock company, trust, estate, governmental
entity, or any other legal entity; or their legal representatives,
agents, or assigns. This definition includes all federal, state, and
local governmental entities.

wastes, biological materials, radioactive materials, heat, wrecked
or discarded equipment, rock, sand, cellar dirt, municipal, agricultural
and industrial wastes, and certain characteristics of wastewater (e.g.,
pH, temperature, TSS, turbidity, color, BOD, COD, toxicity, or odor).
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, introducing such pollutants
into the POTW. This reduction or alteration can be obtained by physical,
chemical, or biological processes; by process changes; or by other
means, except by diluting the concentration of the pollutants unless
allowed by an applicable pretreatment standard.
PRETREATMENT REQUIREMENTS
Any substantive or procedural requirement related to pretreatment
imposed on a user, other than a pretreatment standard.
PUBLICLY OWNED TREATMENT WORKS or POTW
A "treatment works," as defined by Section 212 of the Act
(33 U.S.C. § 1292) which is owned and/or operated by the
City and/or Township. This definition includes any devices or systems
used in the collection, storage, treatment, recycling, and reclamation
of sewage or industrial wastes of a liquid nature and any conveyances
which convey wastewater to a treatment plant.
SEPTIC TANK WASTES
Any sewage from holding tanks such as vessels, chemical toilets,
campers, trailers, and septic tanks.
SEWAGE

operations, etc.).
SIGNIFICANT INDUSTRIAL USER
(1)
A user subject to categorical pretreatment standards; or
(2)
A user that:
(a)
Discharges an average of 25,000 gpd or more of process wastewater
to the POTW (excluding sanitary, noncontact cooling, and boiler blowdown
wastewater);
(b)
Contributes a process waste stream which makes up 5% or more
of the average dry weather hydraulic or organic capacity of the POTW
treatment plant; or

reasonable potential for adversely affecting the POTW's operation
or for violating any pretreatment standard or requirement.
(3)
Upon a finding that a user meeting the criteria in Subsection
(2) has no reasonable potential for adversely affecting the POTW's operation or for violating any pretreatment standard or requirement, the Superintendent may, at any time, on his own initiative or in response to a petition received from a user, and in accordance with procedures in 40 CFR 403.8(f)(6), determine that such user should not be considered a significant user.
SLUG LOAD or SLUG
Any discharge of a non-routine, episodic nature, or at a flow rate or concentration which would cause a violation of the prohibited discharge standards in §
102-48A of this article, has the reasonable potential to cause interference or pass-through or in any other way violate the POTW's regulations, local limits or permit conditions.
