CITY
The City of Union, Missouri.
CITY ENGINEER, PUBLIC WORKS DIRECTOR, OR SUPERINTENDENT
The person designated by the City to supervise or oversee
the operation of the POTW, and who is charged with certain duties
and responsibilities by this Article. The term also means a duly authorized
representative of the City Engineer, Public Works Director, or Superintendent.
DAILY MAXIMUM
The arithmetic average of all effluent samples for a pollutant
collected during a calendar day.
DAILY MAXIMUM LIMIT
The maximum allowable discharge limit of a pollutant during
a calendar day. 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.

to the flow in the waste stream and over a period of time not to exceed
fifteen (15) minutes.
INSTANTANEOUS 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 that, 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 any more stringent State or local
regulations: § 405 of the Act; the Solid Waste Disposal
Act, including Title II, commonly referred to as the "Resource Conservation

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 § 307(c) of the Act that 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; 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 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 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 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 Subsection.
NON-CONTACT COOLING WATER
Water used for cooling that 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.
pH
A measure of the acidity or alkalinity of a solution, expressed
in standard units.
POLLUTANT

sewage, garbage, sewage sludge, munitions, medical wastes, chemical
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.
PUBLIC WORKS DIRECTOR, CITY ENGINEER, OR SUPERINTENDENT
The person designated by the City to supervise or oversee
the operation of the POTW, and who is charged with certain duties
and responsibilities by this Article. The term also means a duly authorized
representative of the City Engineer, Public Works Director, or Superintendent.
PUBLICLY OWNED TREATMENT WORKS OR POTW
A treatment works, as defined by § 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.
SEPTIC TANK WASTE
Any sewage from holding tanks such as vessels, chemical toilets,
campers, trailers, and septic tanks.
SEWAGE
Human excrement and gray water (household showers, dishwashing
operations, etc.).
SIGNIFICANT INDUSTRIAL USER (SIU)
Except as provided in Subsections (3) and (4) of this definition,
a significant industrial user is:
1.
An industrial user subject to categorical pretreatment standards;
or
2.
An industrial user that:
a.
Discharges an average of twenty-five thousand (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 five percent
(5%) 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.
The City may determine that an industrial user subject to categorical
pretreatment standards is a non-significant categorical industrial
user rather than a significant industrial user on a finding that the
industrial user never discharges more than one hundred (100) gallons
per day (gpd) of total categorical wastewater (excluding sanitary,
non-contact cooling and boiler blowdown wastewater, unless specifically
included in the pretreatment standard) and the following conditions
are met:
a.
The industrial user, prior to the City's finding, has consistently
complied with all applicable categorical pretreatment standards and
requirements;
b.
The industrial user annually submits the certification statement
required in § 6.14B [see 40 CFR 403.12(q)], together with
any additional information necessary to support the certification
statement; and
c.
The industrial user never discharges any untreated concentrated
wastewater.
4.
Upon a finding that a user meeting the criteria in Subsection
(2) of this definition 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 an industrial 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 OR SLUG DISCHARGE
Any discharge at a flow rate or concentration which could cause a violation of the prohibited discharge standards in Section
710.190 of this Article. A slug discharge is any discharge of a non-routine, episodic nature, including but not limited to an accidental spill or a non-customary batch discharge, which has a reasonable potential to cause interference or pass through, or in any other way violate the POTW's regulations, local limits or permit conditions.
STORMWATER
Any flow occurring during or following any form of natural
precipitation, and resulting from such precipitation, including snowmelt.
SUPERINTENDENT, CITY ENGINEER, OR PUBLIC WORKS DIRECTOR
The person designated by the City to supervise or oversee
the operation of the POTW, and who is charged with certain duties
and responsibilities by this Article. The term also means a duly authorized
representative of the Superintendent, City Engineer, or Public Works
Director.
WASTEWATER
