No person shall discharge or cause to be discharged
any unpolluted waters, such as stormwater, groundwater, roof runoff,
subsurface drainage or cooling water, to any sanitary sewer.
Stormwater and all other unpolluted drainage
shall be discharged to such sewers as are specifically designated
as storm sewers or to a natural outlet approved by the Superintendent
and other regulatory agencies. The discharge of unpolluted industrial
cooling water or process waters requires a NYSDEC SPDES permit and
is subject to federal and state regulations.
Each user of the Chittenango sewage treatment
plant will comply with all applicable federal categorical pretreatment
standards and requirements.
Except as hereinafter provided, no person shall
discharge or cause to be discharged any of the following-described
waters or wastes to any public sewer:
A.
Any water or wastes with heat in amounts which will
inhibit biological activity in the sewage treatment plant, resulting
in interference. In no case shall the temperature of the liquid or
vapor exceed 65° C. (150° F.) or such wastes be discharged
in quantities such that the temperature at the sewage treatment plant
influent exceeds 40° C. (104° F.) unless the plant is designed
to accommodate such heat.
B.
Any waters or wastes which contain grease or oil or
other substance that will solidify or become discernibly viscous at
temperatures between 32° and 150° F.
C.
Any waters or wastes containing fats, wax, grease
or oils, whether emulsified or not, exceeding an average of 50 milligrams
per liter (417 pounds per million gallons) or other soluble matter.
D.
Any gasoline, benzine, naphtha, fuel oil or mineral
oil or other flammable or explosive liquid, solid or gas.
E.
Any noxious or malodorous gas, such as hydrogen sulfide,
sulfur dioxide or nitrous oxide, or other substance which, either
singly or by interaction with other wastes, is capable of creating
a public nuisance or hazard to life or preventing entry into sewers
for their maintenance and repair.
F.
Any garbage that has not been properly shredded. The
installation and operation of any garbage grinder equipped with a
motor of 3/4 horsepower or greater shall be subject to the review
and approval of the Superintendent.

cesspool, or the discharge or effluent from any air-conditioning machine
or refrigeration unit.
M.
Any waters or wastes containing a toxic or poisonous
substance, a high chlorine demand or suspended solids in sufficient
quantity to injure or interfere with any sewage treatment process,
constitute a hazard to humans or animals or create any hazard in the
receiving waters or the effluent of the sewage treatment plant. Such
toxic substances shall be limited to the average concentrations listed
hereinafter in the sewage as it arrives at the treatment plant, and
at no time shall the hourly concentration at the sewage treatment
plant exceed three times the average concentration. If concentrations

A.
If any waters or wastes are discharged or are proposed to be discharged to the public sewers, which waters contain the substances or possess the characteristics enumerated in § 115-45 and which, in the judgment of the Superintendent, may have a deleterious effect upon the sewage works, processes, equipment or receiving waters or which otherwise create a hazard to life or constitute a public nuisance, the Superintendent may recommend to the Board one or more of the following:
B.
If the Superintendent permits the pretreatment or
equalization of waste flows, the design and installation of the plants
and equipment shall be subject to the review and approval of the Board
and subject to the requirements of all applicable codes, ordinances
and laws.
A.
Grease, oil and sand interceptors shall be provided
when, in the opinion of the Superintendent, they are necessary for
the proper handling of liquid wastes containing grease in excessive
amounts or any flammable wastes, sand and other harmful ingredients,
except that such interceptors shall not be required for private living
quarters or dwelling units. All interceptors shall be of a type and
capacity approved by the Superintendent and shall be located as to
be readily and easily accessible for cleaning and inspection.
B.
Grease and oil interceptors shall be constructed of
impervious materials capable of withstanding abrupt and extreme changes
in temperatures. They shall be of substantial construction, watertight
and equipped with easily removable covers which, when bolted in place,
shall be gastight and watertight.
C.
Where installed, all grease, oil and sand interceptors
shall be maintained by the owner, at his expense, in continuously
efficient operation at all times and shall be readily accessible and
open to inspection by the Superintendent at any time.
The admission into the public sewers of any waters or wastes having a five-day biochemical oxygen demand greater than 300 milligrams per liter, or containing more than 350 milligrams per liter of suspended solids, or containing more than 15 milligrams per liter of chlorine requirement, or containing any quantity of substances having the characteristics described in § 115-45, or having an average daily flow greater than 2% of the average daily sewage flow of the Village shall be subject to the review and approval of the Engineer or Superintendent. Where necessary, in the opinion of the Engineer or Superintendent, the owner shall provide, at his expense, such preliminary treatment as may be necessary to reduce the biochemical oxygen demand to 300 milligrams per liter and the suspended solids to 350 milligrams per liter by weight, or reduce the chlorine requirements to 15 milligrams per liter, or reduce objectionable characteristics or constituents to within the maximum limits provided for in § 115-45, or control the quantities and rates of discharge of such waters or wastes. When pretreatment standards are adopted by the United States Environmental Protection Agency and the New York State Department of Environmental Conservation for any given class of industries, then such industries must immediately conform to the timetable for adherence to these standards. Plans, specifications and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for the approval of the Engineer and of the New York State Department of Environmental Conservation, and no construction of such facilities shall be commenced until said approvals are obtained in writing. Failure to comply with one or more of the remedial procedures as required by the Engineer or Superintendent will constitute a violation of this chapter.
Where preliminary treatment or flow equalizing
facilities are provided for any waters or wastes, they shall be maintained
continuously in satisfactory and effective operation by the owner
at his expense.
When required by the Superintendent, the owner
of any property served by a building sewer carrying industrial wastes
shall install a suitable control manhole, together with such necessary
meters and other appurtenances in the building sewer, to facilitate
observation, sampling and measurement of the wastes. Such manhole,
when required, shall be accessibly and safely located and shall be
constructed in accordance with plans approved by the Superintendent.
The manhole shall be installed by the owner at his expense and shall
be maintained by him so as to be safe and accessible at all times.
The Superintendent may require a user of sewer
services to provide information needed to determine compliance with
this chapter. These requirements may include:
A.
Wastewaters discharge peak rate and volume over a
specified time period.
B.
Chemical analyses of wastewaters.
C.
Information on raw materials processes and products
affecting wastewater volume and quality.
D.
Quantity and disposition of specific liquid, sludge,
oil, solvent or other materials important to sewer use control.
E.
A plot plan of sewers on the user's property showing
sewer and pretreatment facility location.
F.
Details of wastewater pretreatment facilities.
G.
Details of systems to prevent and control the losses
of materials through spills to the municipal sewer.
All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in this chapter shall be determined in accordance with the most recent edition of Standard Methods for the Examination of Water and Wastewater upon suitable samples taken at the control manhole provided for in § 115-50. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewage works and to determine the existence of hazards to life, limb and property. The particular analysis involved will determine whether a twenty-four-hour composite of all outfalls of a premise is appropriate or whether a grab sample or samples should be taken. Normally, but not always, BOD and suspended solids analyses are obtained from twenty-four-hour composites of all outfalls whereas pH's are determined from periodic grab samples.
A.
Nothing in this article shall be construed as preventing
any special agreement or arrangement between the Village and user
of the wastewater facilities whereby wastewater of unusual strength
or character is accepted into the system and specially treated, subject
to any payments or user charges as may be applicable.
B.
In entering into such a special agreement, the Village
Board must consider whether the agreement will:
C.
No discharge in violation of federal pretreatment
standards will be allowed under the terms of such special agreements.
All of the preceding standards are to apply
at the point where the industrial wastes are discharged into the public
sanitary sewerage system. Any chemical or mechanical corrective treatment
required must be accomplished to practical completion before the wastes
reach that point. The laboratory methods used in the examination of
all industrial wastes shall be those set forth in the latest edition
of Standard Methods for the Examination of Water and Wastewater published
by the American Public Health Association. However, alternate methods
for the analysis of industrial wastes may be used, subject to mutual
agreement between the Village Board and the producer of such wastes.
The frequency and duration of the sampling of any industrial waste
shall not be less than once every three months for a twenty-four-hour
period. However, more frequent and longer periods may be required
at the discretion of the Village Board.
No user shall ever increase the use of process
water or in any way attempt to dilute a discharge as a partial or
complete substitute for adequate treatment to achieve compliance with
the limitations contained in the federal categorical pretreatment
standards or in any other pollutant specific limitation developed
by the Village or state unless authorized by state or federal regulations.
A user shall notify the Village and the operator
of the POTW immediately upon accidentally discharging wastes in violation
of this chapter. This notification shall be followed, within 15 days
of the date of occurrence, by a detailed statement describing the
causes of the accidental discharge and the measures being taken to
prevent future occurrence. Such notification will not relieve users
from liability for any expense, loss or damage to the sewer system,
treatment plant or treatment process or for any fines imposed on the
Village under applicable state and federal regulations.
