calculated by adding all the daily discharges measured during the
calendar month and dividing the sum by the number of daily discharges
measured during that month.

calculated by adding all the daily discharges measured during a calendar
week and dividing the sum by the number of daily discharges measured
during that week.

The quantity of oxygen utilized in the biochemical oxidation
of organic matter under standard laboratory procedures, after five
days at 20° C., expressed in terms of weight and concentration
(milligrams per liter).

A sewer conveying wastewater from the premises of a user
to the POTW.
CATEGORICAL STANDARD
Any regulation containing pollutant discharge limits promulgated by the U.S. EPA in accordance with Sections 307(b) and (c) of the Act (33 U.S.C. § 1317), which applies to a specific category of industrial users, and which appears in 40 CFR Chapter
1, Subchapter N, Parts 405 through 471, and is incorporated in this article by reference.
COMPOSITE SAMPLE
A combination of individual samples of water or wastewater

DAILY DISCHARGE
The discharge of a pollutant measured during a calendar day
or any twenty-four-hour period that reasonably represents the calendar
day for purposes of sampling. For pollutants with limitations expressed
in units of weight, daily discharge is calculated as the total mass
of the pollutant discharged over the day. For pollutants with limitations
expressed in other units of measurement, daily discharge is calculated
as the average measurement of the pollutant over the day.
DIRECTOR OF PUBLIC WORKS (DPW)

including those discharges that prevent the use or disposal of sludge
by the POTW in accordance with any federal or state laws, regulations,

NEW SOURCE
A.
Any source of a discharge, the construction or operation of
which commenced after the publication of proposed categorical pretreatment
standards under Section 307(c) of the Act [33 U.S.C. § 317(c)]

promulgated in accordance with Section 307(c), provided that:
(1)
No other source is located at that site;
(2)
The source completely replaces the process or production equipment
of an existing source at that site; or
(3)
The new wastewater generating process of the source is substantially
independent of an existing source at that site and the construction
of the source creates a new facility rather than modifies an existing
source at that site.
B.
For purposes of this definition, construction or operation has
commenced if the owner or operator has:
(1)
Begun, or caused to begin, as part of a continuous on-site construction
program:
(a)
Any placement, assembly, or installation of facilities or equipment;
(b)
Significant site preparation work, including clearing, excavation,

are necessary for the placement, assembly, or installation of new
source facilities or equipment; or
(2)
Entered into a binding contractual obligation for the purchase
of facilities or equipment which are intended to be placed in 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 contractual
obligations under this definition.
PASS-THROUGH

or concentrations which cause, in whole or in part, a violation of
any requirement of the POTW's VPDES permits, including an increase
in the magnitude or duration of a violation.
pH

wrecked or discharged equipment, rock, sand, cellar dirt, or agricultural
waste.
POLLUTION
The manmade or man-induced alteration of the chemical, physical,
biological, or radiological integrity of water.
PRETREATMENT
The reduction of the amount of pollutants, the elimination
of pollutants, or the alteration of the nature of pollutant properties
in wastewater to a less harmful state prior to or in lieu of discharging
or otherwise introducing such pollutants into the POTW. Such reduction
or alteration may be obtained by physical, chemical, or biological
processes, process changes, or by other lawful means.
PRETREATMENT STANDARD OR REQUIREMENT
Any substantive or procedural requirement related to pretreatment,
including national pretreatment categorical standards, or prohibitive
discharge standards, and local limits imposed on an industrial user.

causing pass-through or interference at either the City's or
the county's POTW.
SIGNIFICANT NONCOMPLIANCE

of wastewater measurements taken during a six-month period equal or
exceed 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 pollutants except pH);
(3)
Any other violation of an effluent limit (average or daily maximum)
that the City has reason to believe has caused, alone or in combination
with other discharges, interference, pass-through, sludge contamination,
or the endangerment of the health of sewage treatment personnel or
the public; or
(4)

to human health or to the environment or has resulted in the City's
exercise of administrative enforcement action to halt or prevent such

to aquatic life, detrimental effects on human health, or other adverse
environmental effects.
TOXIC POLLUTANT
Any material, including, but not limited to, those listed
under Section 307(a) of the Act, which, after discharge, will, on
the basis of available information, cause toxicity.
UPSET
An exceptional incident in which there is unintentional and
temporary noncompliance with technology-based permit effluent limitations
due to factors beyond the permittee's reasonable control. An
upset does not include noncompliance caused by operational error,
improperly designed treatment facilities, inadequate treatment facilities,
lack of preventive maintenance, or careless or improper operation.
