a grab sample.
ENVIRONMENTAL PROTECTION AGENCY (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

pretreatment standards which will be applicable to such source if
the standards are thereafter promulgated in accordance with Section
307 of the Act.

or business or from the development or recovery of any natural resources.
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 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 more stringent state or local regulations):
Section 405 of the Clean Water Act; the Solid Waste Disposal Act (SWDA),
including Title II, commonly referred to as the "Resource Conservation

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

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 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 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 at 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 subsection
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, including clearing, excavation,
or removal of existing buildings, structures or facilities, which
is necessary for 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 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.
NON-CONTACT 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, are 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 its legal representatives, agents,
or assigns. This definition includes all federal, state, or local
government entities.
pH
A measure of the acidity or alkalinity of a substance, expressed
in standard units.
POLLUTANT
Any dredged spoil, solid waste, residue, sewage, garbage,
sewage sludge, munitions, medical wastes, chemical wastes, biological
materials, radioactive materials, heat, wrecked or discharged equipment,
rock, sand, cellar dirt, agricultural and industrial wastes and the
characteristics of the wastewater [i.e., pH, temperature, TSS, turbidity,
color, BOD, chemical oxygen demand (COD), toxicity, or odor].
PRETREATMENT
The reduction of the amount of pollutants, the elimination
of the 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 (POTW)
A treatment works, as defined by Section 212 of the Act (33
U.S.C. § 1292), which is owned by the City. 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. The term also means the City.
SEWAGE
Human excrement and gray water (household showers, household
dishwashing 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, non-contact cooling, and boiler blowdown
wastewater);
(b)
Contributes a process waste stream which makes up 5% or more
of the average dry hydraulic or organic capacity of the POTW treatment
plant; or
(c)
Is designated as such by the City on the basis that it has a
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 City may at any time, on its 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 industrial user.
SLUG LOAD
Any discharge at a flow rate or concentration which could cause a violation of the prohibited discharge standards in §
375-26A of this article or any discharge of a nonroutine, episodic nature, including but not limited to an accidental spill or a noncustomary batch discharge.
STORMWATER

removable by laboratory filtering.
TOXIC POLLUTANT
One of 126 pollutants, or combination of those pollutants,
listed as toxic in regulations promulgated by the EPA under Section
307 of the Act (33 U.S.C. § 1317).
WASTEWATER
Liquid and water-carried industrial wastes and sewage from
residential dwellings, commercial buildings, industrial and manufacturing
facilities, and institutions, whether treated or untreated, which
are contributed to the POTW.
