response plan adopted by the POTW.
The following words, terms and phrases, when used in this Part
4, shall have the meanings ascribed to them in this section, except where the context clearly indicates a different meaning:
ALTERNATIVE DISCHARGE LIMIT
Limits set by the YCUA in lieu of the promulgated National
Categorical Pretreatment Standard for integrated facilities in accordance
with the combined wastestream formula as set by the EPA.
AUTHORIZED REPRESENTATIVE OF INDUSTRIAL USER
A.
A responsible corporate officer, if the industrial user is a
corporation, who shall be a president, secretary, treasurer, or vice
president of the corporation in charge of a principal business function,
or any other person who performs similar policy or decisionmaking
functions for the corporation; or the principal manager of one or
more manufacturing, production, or operation facilities employing
more than 250 persons or having a gross annual sales or expenditures
exceeding $25,000,000 (in second quarter 1980 dollars) if authority
to sign documents has been assigned or delegated to the manager in
accordance with corporate procedures;
B.
A general partner or proprietor if the industrial user is a
partnership or proprietorship, respectively;
C.
A duly authorized representative of the individual designated
above and if all of the following apply:
(1)
The authorization is made in writing by the individual described in Subsection
A or
B of this definition;
(2)
This authorization specifies either an individual or a position
having responsibility for the overall operation of the facility from
which the industrial discharge originates, such as the position of
plant manager, operator of a well, or well field superintendent, or
a position of equivalent responsibility, or having overall responsibility
for environmental matters for the company; and
(3)
The written authorization is submitted to the Director. If an
authorization is no longer accurate because a different individual
or position has responsibility for the overall operation of the facility,
or overall responsibility for environmental matters for the company,
a new authorization satisfying the requirements of this definition
shall be submitted to the Director prior to or together with any reports
to be signed by an authorized representative.
BEST MANAGEMENT PRACTICES (BMP)
Programs, practices, procedures or other directed efforts,
initiated and implemented by users, which can or do lead to the reduction,
conservation or minimization of pollutants being introduced into the
ecosystem, including but not limited to the YCUA publicly owned treatment
system. BMPs include, but are not limited to, equipment or technology
modifications, process or procedure modifications, reformulation or
design of products, substitution of raw materials, and improvements
in housekeeping, maintenance, training, or inventory control, and
may include technical and economic considerations. BMP's may
be structural or nonstructural or both. In determining what BMPs will
be required of a user in a particular case, the Director may consider
all relevant technological, economical, practical, and institutional
considerations as determined relevant and appropriate by the Director,
consistent with achieving and maintaining compliance with the requirements
of this Part 4 and other applicable laws and regulations.
BIOCHEMICAL OXYGEN DEMAND (BOD)
The quantity of oxygen utilized in the biochemical oxidation
of organic matter under standard laboratory procedure, five days at
20° C. expressed in terms of weight and concentration (milligrams
per liter).
BOARD
The Board of Trustees of Pittsfield Charter Township.
BUILDING DRAIN
That part of the lowest horizontal piping of a drainage system
which receives the drainage from soil, waste and other drainage pipes
inside the walls of the building and conveys it to the building sewer,
beginning five feet outside the inner face of the building wall.
BUILDING SEWER
That extension from the building drain to the public sewer
or other places of disposal. The building sewer includes all pipe
and or conduit, which transports waste from the building up to and
including any connection to the public sewer. The Township shall not
be responsible for any sewer from the point of connection, including
the connection itself, to the building even if the sewer is located
within the public right-of-way.
BYPASS
Intentional diversion of waste streams from any portion of
an industrial user's treatment facility.
CHEMICAL OXYGEN DEMAND (COD)
A measure of the oxygen-consuming capacity of inorganic and
organic matter present in water or wastewater. It is expressed as
the amount of oxygen consumed from a chemical oxidant in a specified
test. It does not differentiate between stable and unstable organic
matter and thus does not necessarily correlate with biochemical oxygen
demand. Also known as OC and DOC, oxygen consumed and dichromate oxygen
consumed, respectively.
CHLORINE DEMAND
The difference between the amount of chlorine added to water
or wastewater and the amount of residual chlorine remaining at the
end of a specified contact period. The demand for any given water
varies with the amount of chlorine applied, time of contact and temperature.
COMBINED WASTESTREAM
The wastestream at industrial facilities where regulated
process effluent is mixed with other wastewaters (either regulated
or unregulated) prior to treatment.
COMPATIBLE POLLUTANT
A substance amenable to treatment in the wastewater treatment
plant such as biochemical oxygen demand, suspended solids, pH and
fecal coliform bacteria, plus additional pollutants identified in
the NPDES permit if the publicly owned treatment works was designed
to treat such pollutants, and in fact does remove such pollutant to
a substantial degree. Examples of such additional pollutants may include:
chemical oxygen demand, total organic carbon, phosphorus and phosphorus
compounds, nitrogen compounds, fats, oils and greases of animal or
vegetable origin.
COMPOSITE SAMPLE
A sample formed either by continuous sampling or by mixing
discrete samples obtained at intervals over a period of time. The
individual samples which shall be obtained through flow-proportional
composite sampling techniques, unless time-proportional composite
sampling or grab sampling is authorized by the YCUA. Where time-proportional
composite sampling or grab sampling is authorized by the YCUA, the
samples must be representative of the discharge. Manual generation
of a composite sample through the collection and combining of grab
samples may be approved if the user demonstrates to the satisfaction
of the Director that this will provide a representative sample of
the effluent being discharged. The decision to allow the alternative
sampling must be documented in the industrial user's file for
that facility or facilities. Composite sampling protocols delineated
in the user's permit take precedence.
COOLING WATER
The water discharged from any use such as air conditioning,
cooling or refrigeration, or to which the only pollutant added is
heat.
DAILY MAXIMUM
The concentration or mass loading that shall not be exceeded
on any single calendar day. Where daily maximum limitations are expressed
in terms of a concentration, the daily discharge is the arithmetical
average measurement of the pollutant concentration derived from all
measurements taken that day. Where daily maximum limitations are expressed
in units of mass, the daily discharge is the total mass discharged
during the day. If a composite sample is required for a parameter,
the determination whether the daily maximum limitation for that parameter
has been exceeded on a single calendar day shall be based on the composite
sample collected for that parameter on that calendar day. If grab
samples are required for a parameter, the determination whether the
daily maximum limitation for that parameter has been exceeded on a
calendar day shall be based on the average of all grab samples collected
for that parameter on that calendar day. If only one grab sample is
collected for a parameter on a given day, the determination whether
the daily maximum limitation for that parameter has been exceeded
for the day shall be based on the results of that single grab sample.
If the pollutant concentration in any sample is less than the applicable
detection limit, that value shall be regarded as zero when calculating
the daily maximum concentration.
DEBT SERVICE CHARGES
The charges levied to customers of the wastewater system,
which are used to pay principal, interest and administrative costs
of retiring the debt incurred for construction of the sewage works.

The maximum concentration of a pollutant allowed to be discharged
at any instant in time (independent of the flow rate or duration of
the sampling event). If the concentration determined by analysis of
any grab sample, composite sample, or discrete portion of a composite
sample exceeds the instantaneous maximum concentration, the instantaneous
maximum concentration shall be deemed to have been exceeded. Any discharge
of a pollutant at or above a specified instantaneous maximum concentration
is a violation of this Part 4 and the YCUA or POTW industrial pretreatment
program.

after the publication of proposed pretreatment standards under Section
307(c) of the Clean Water Act will be applicable to the source if
the standards are thereafter promulgated in accordance with Section
307(c), and if any of the following provisions apply:
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.
