users and which appear in 40 CFR chapter I, subchapter N, parts 405–471.
Composite wastewater sample.
A combination of individual samples of water or wastewater
taken at selected intervals, generally hourly for some specified period,
to minimize the effect of the variability of the individual sample.
Individual samples may have equal volume or may be roughly proportioned

measured during that month.
Daily maximum limit.
The maximum concentration (or loading) of a pollutant allowed
to be discharged during a calendar day or any 24-hour period that
reasonably represents the calendar day for purposes of sampling. For
pollutants with limitation expressed in units of mass, it is calculated
as the total mass of the pollutant discharged over the day. For pollutants
with limitations expressed in other units of measurement, it is calculated
as the average measurement of the pollutant over the day.

which commenced prior to the publication by the 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.

and discharged, permitted to flow, or escaping from any industrial,
manufacturing, or food-processing operation or process, or from the
development of any natural resource including oil or gas, or any mixture
of these with water or domestic wastewater. (This term is generally
synonymous with “nondomestic wastewater” or nondomestic
waste.)
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
discrete or composite 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 or of the prevention of sewage sludge use or disposal
in compliance with any of the following statutory/regulatory provision
or permits issued thereunder (or 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 Act; and the Marine Protection,
Research, and Sanctuaries Act.
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 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 section (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:
(i)
Any placement, assembly, or installation of facilities or equipment;
or
(ii)
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 that are intended to be used in its operation
within a reasonable time. Options to purchase or contract 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, pollutant, intermediate product, waste product,
or finished product.
Normal waste.
Waste which, when analyzed, indicates that:
(1)
The concentration of biochemical oxygen demand (BOD) in the
waste will not exceed two hundred milligrams per liter (200 mg/l)
average over any 24-hour period;
(2)
The concentration of total suspended solids (TSS) in the waste
will not exceed two hundred milligrams per liter (200 mg/l) average
over any 24-hour period;
(3)
The concentration of total organic carbon (TOC) in the waste
will not exceed two hundred milligrams per liter (200 mg/l) average
over any 24-hour period;
(4)
The concentration of free or emulsified animal oil, vegetable
oil or grease (FOG) will not exceed one hundred milligrams per liter
(100 mg/l); and
(5)
The concentration of total petroleum hydrocarbons (TPH) will
not exceed twenty milligrams per liter (20 mg/l).
Pass-through.
A discharge which exits the POTW into water of the United
States in quantities or concentration 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, co-partnership, firm, company,
corporation, association, joint stock company, trust, estate, governmental
entity; or their legal representatives, agents, or assigns. This definition
includes all federal, state, and local governmental entities.

or discarded equipment, rock, sand, dirt, municipal, agricultural
and industrial waste, and certain characteristics of wastewater (i.e.,
pH, temperature, TSS, turbidity, color, BOD, chemical oxygen demand
(COD), toxicity, 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.

of the act (33 U.S.C. section 1292) that 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.

Contributes a process wastestream which makes up five (5) percent
or more of the average dry weather 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 director 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.
