No person shall discharge or cause to be discharged any stormwater, groundwater, roof runoff, subsurface drainage or drainage from downspouts, yard drains, sump pumps, yard foundations and ponds or lawn sprays into any sanitary sewer, except as provided by the Town of Tonawanda Code. Water from swimming pools and unpolluted industrial water, such as water drains, blowoff pipes or cooling water from various equipment, shall not be discharged into sanitary sewers if a closed storm sewer is available. If a closed storm sewer is not available, such water may be discharged into the sanitary sewer by indirect connection whereby such discharge is cooled, if required, and flows into the sanitary sewer at a rate not in excess of five gallons per minute, provided that the waste does not contain materials or substances in suspension or solution in violation of the limits prescribed by this Part
1.
No person shall transfer title to another person nor accept from any other person the transfer of title to any structure or parcel of land upon which a structure is located unless and until the Plumbing Inspector or other authorized agents of the Town shall have inspected the sump pump system, footing drains, yard drains and downspouts on said structure or parcel of land and issued a certificate of compliance stating that the same is found to be in compliance with the provisions of this chapter, specifically Article
IV, §
165-18, restricting the discharge of unpolluted waters into the sanitary system. This section shall not apply to transfers of property by gift, intestacy or testamentary disposition, transfers pursuant to the Federal Bankruptcy Act, transfers for which consideration is $100 or less and transfers in connection with a partition.
[Amended 3-26-2007 by L.L. No. 2-2007]
A. The Code Enforcement Officer may temporarily waive the requirement of a certificate of compliance as a prerequisite to transfer of title, as specified in §
165-18.1, provided that the purchaser:
(1)
Shall have filed with the Code Enforcement Officer
a written guaranty to correct any deficiencies to the sump pump system,
footing drains, yard drains and downspouts within a period of time
to be specified by the Code Enforcement Officer; and
(2)
Shall have provided a sum of $1,500, which shall
be held in escrow, and which sum shall be returned to the purchaser
if the corrections are completed within the time specified in the
guaranty, but which sum shall be forfeited to the Town of Tonawanda
if needed corrections are not completed within the time specified
in the written guaranty.
B. In the event that the needed corrections are not completed within the time specified in the written guaranty, the temporary waiver issued by the Code Enforcement Officer shall immediately expire and the purchaser shall be subject to the penalties prescribed in Article
VI hereof.
No person shall discharge or cause to be discharged
any of the following described waters or wastes to any public sewer:
A. Any pollutants such as gasoline, benzene, naphtha,
fuel oil or other flammable or explosive liquid, solid or gas or any
pollutant which creates a fire or explosion hazard in the POTW, including,

less than 140° F. or 60° C. using the test methods specified
in 40 CFR 261.21.
B. Any waters or wastes containing solids, liquids or
gases which, by reason of their nature or quantity, are or may, singly
or by interaction with other wastes, cause injury or interfere with
any sewage treatment process, constitute a hazard to humans or animals,
create a public nuisance or create any hazard in the receiving waters
of the sewage treatment plant; any wastewater containing toxic pollutants
in sufficient quantity, either singly or by interaction with other
pollutants, to injure or interfere with any wastewater treatment process,
constitute a hazard to humans, animals, create a toxic effect in the
receiving waters of the treatment works or to exceed the limitations
set forth in a categorical pretreatment standard. A "toxic pollutant"
shall include, but not be limited to, any pollutant identified pursuant
to Section 307 (a) of the Federal Act.
C. Any waters or wastes having a pH lower than 5.0 or
in excess of 9.5 or having any other corrosive property capable of
causing damage or hazard to structures, equipment and personnel of
the sewage works.
D. Solid or viscous substances in quantities or of such
size capable of causing obstruction to the flow in sewers or other
interference with the proper operation of the sewage works, such as
but not limited to ashes, cinders, sand, mud, straw, shavings, metal,

wastes or concentrated plating solutions, whether neutralized or not.
H. Any substance which may cause the treatment works'
effluent or any other product of the treatment works, such as residues,
sludges or scums, to be unsuitable for reclamation and reuse to interfere
with the reclamation process where the treatment works is pursuing
a reuse and reclamation program. In no case shall a substance discharged
to the treatment works cause the treatment works to be in noncompliance
with sludge use or disposal criteria, guidelines or regulations developed
under Section 405 of the Federal Act and criteria, guidelines or regulations
affecting sludge use or disposal developed pursuant to the Solid Waste
Disposal Act, the Clean Air Act, the Toxic Substances Control Act
or Department of Environmental Conservation criteria applicable to
the sludge management method being used.
I. Any pollutants, including chlorine-demanding or oxygen-demanding
pollutants (BOD, chlorine demand etc.), released at a flow rate and/or
pollutant concentration which a user knows or has reason to know will
cause interference or pass-through at the Town of Tonawanda POTW.
In no case shall a slug load have a flow rate or contain concentration
or qualities of pollutants that exceed for any time period longer
than 15 minutes more than five times the average twenty-four-hour
concentration, quantities or flow during normal operation.
J. Any wastewaters containing radioactive wastes or isotopes
of such half-life or concentration as may exceed limits established
by the Pretreatment Administrator in compliance with applicable state
or federal regulations.
K. Any wastewater having a temperature which will inhibit
biological activity in the treatment works, resulting in interference,
but in no case wastewater with a temperature at the introduction into
the sewer system which exceeds 150° F. (65.5° C.) unless the
treatment works is designed to accommodate such temperature or in
such quantities that the temperature at the treatment works influent
exceeds 104° F. (40° C.).
L. Any discharges of petroleum, oil, nonbiodegradable
cutting oil or products of mineral oil origin that will cause interference
or pass-through.
M. Waters or wastes containing substances which are not
amenable to treatment or reduction by the sewage treatment processes
employed or are amenable to treatment only to such degree that the
sewage treatment plant effluent cannot meet the requirements of other
agencies having jurisdiction over discharge to receiving waters.
N. Any trucked or hauled pollutants, except at discharge
points designated by the POTW.
No person shall discharge or cause to be discharged
the following described substances, materials, waters or wastes if
it appears likely, in the opinion of the Pretreatment Administrator,
that such wastes, in addition to similar wastes from other dischargers,
can harm either the sewers, sewer treatment process or equipment,
have an adverse effect on the receiving stream or can otherwise endanger
life, limb or public property or constitute a nuisance. In forming
his opinion as to the acceptability of these wastes, the Pretreatment
Administrator will give consideration to such factors as the quantities
of subject wastes, including similar wastes from other users, in relation
to flows and velocities in the sewers, construction materials of the
sewers, nature of the sewage treatment process, capacity of the sewage
treatment plant, degree of treatability of wastes in the sewage treatment
plant and other pertinent factors. The restricted substances are:
A. Any commercial, institutional or industrial wastes
containing total oils and greases, whether floatable or emulsified,
in a concentration exceeding 300 milligrams per liter (mg/l) or total
extractable hydrocarbons, whether floatable or emulsified, in excess
of 100 mg/l at any time as measured by the analysis of a single grab
sample.
B. Any garbage that has not been properly shredded. The
installation and operation of any garbage grinder equipped with a
motor of 3/4 horsepower (0.76 horsepower metric) or greater shall
be subject to the review and approval of the Pretreatment Administrator.
C. Any waters or wastes containing phenois or other taste-
or odor-producing substances in such concentrations exceeding limits,
which may be established by the Pretreatment Administrator as necessary,
after treatment of the composite sewage, to meet the requirements
of the state, federal or other public agencies of jurisdiction for
such discharge to the receiving waters.
D. Materials which exert or cause:
(1) Unusual concentrations of inert suspended solids,
such as but not limited to fuller's earth, lime slurries and lime
residues, or of dissolved solids, such as but not limited to sodium
chloride and sodium sulfate.
(2) Excessive discoloration, such as but not limited to
dye wastes and vegetable tanning solutions, where, in the opinion
of the Pretreatment Administrator, such discoloration would not be
removed in the treatment process.
(3) Unusual BOD, chemical oxygen demand or chlorine requirements
in such quantities as to constitute a significant load on the sewage
treatment works.
(4) Unusual volume of flow or concentration of wastes
constituting slugs as defined herein.
E. Any water or waste that contains more than 10 parts
per million of the following gases: hydrogen sulfide, sulphur dioxide
or nitrous oxide.
F. Drains receiving acid waste shall be constructed of
any acid-resisting material. Such drains located outside of a building
shall be constructed of vitrified clay or earthenware pipe or other
approved acid-resisting material. Joints shall be constructed by caulking
with asbestos-rope wicking and by pouring a heated sulphur and carbon
compound or a heated bituminous compound in such manner as to secure
tight joints. In no case shall corrosive waste be discharged into
a drain, sanitary sewer, storm sewer or soil or waste pipe without
being first neutralized in such manner as to render such wastes noncorrosive.
These wastes shall be treated by passing through a properly trapped
neutralizing catch basin which shall function automatically.
G. Any water or waste containing hair, fine filament
growth, pile, nap or similar substances that will form a thick, dense
mass or mat.
H. Cooling water shall not be discharged into any public sewer, except in accordance with the provisions of §
165-18 and
165-19 hereof.
Grease, oil and sand interceptors shall be provided
when, in the opinion of the Plumbing Inspector and/or Pretreatment
Administrator, they are necessary for the proper handling of liquid
wastes containing grease in excessive amounts or any flammable wastes,
sand or 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 Plumbing
Inspector or the Pretreatment Administrator and shall be located as
to be readily and easily accessible for cleaning and inspection.
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.
All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in this Part
1 shall be determined in accordance with the laboratory methods set forth in Environmental Protection Agency regulation 40 CFR 136, Approved Analytical Methods.
A. Measurement of flow.
(1) The volume of flow used in computing abnormal sewage
surcharges shall be based upon metered water consumption as shown
in the records of meter readings maintained by the Town Water Department.
In the event that a person discharging waste into the public sewer
system produces evidence to the Pretreatment Administrator demonstrating
that a substantial portion of the total amount of water used for all
purposes does not reach the sewer system, an estimated percentage
of total water consumption to be used in computing charges may be
established by Pretreatment Administrator.
(2) Any person discharging industrial waste into the public
sewers of the Town of Tonawanda who procures any part or all of his
water supply from sources other than the Town Water Department, all
or part of which is discharged into the public sewer, shall install
and maintain at his expense water meters of the type approved by the
Pretreatment Administrator for the purpose of determining the proper
volume of flow to be used in computing sewer service charge. Such
meters shall be read monthly and tested for accuracy when deemed necessary
by the Pretreatment Administrator. Where it can be shown to the satisfaction
of the Pretreatment Administrator that a substantial portion of the
water, as measured by the aforesaid meter or meters, does not enter
the public sewer system of the Town of Tonawanda, then the Pretreatment
Administrator may require or permit the installation of additional
meters at the owner's expense in such manner as to measure the quantity
of water actually entering said public sewerage system from the lot,
parcel of land, building or premises of such owner or occupant, and
the quantity of water used to determine the sewer service charge and
abnormal sewage surcharge may be the quantity of water actually entering
the sewerage system as so determined, if the Pretreatment Administrator
so elects.
B. Determining the character and concentration of waste.
The industrial waste discharged or deposited into the public sewers
shall be subject to periodic inspection and sampling as often as may
be deemed necessary by the Pretreatment Administrator. Samples shall
be collected in such manner as to be representative of the character
and concentration of the waste under operation conditions. The laboratory
methods used in the examination of said waste shall be those set forth
in Environmental Protection Agency regulation 40 CFR 136, Approved
Analytical Methods. The determination of the character and concentration
of industrial waste shall be made by the Pretreatment Administrator
at such times and on such schedules as may be established by the Pretreatment
Administrator. Should an owner or occupant discharging industrial
waste to the public sewers desire a determination of the quality of
such industrial waste to be made at some time other than that scheduled
by the Pretreatment Administrator, such special determination may
be made by the Pretreatment Administrator at the expense of the owner
or occupant discharging the waste.
No statement contained in Part
1 hereof shall be construed as preventing any special agreement or arrangement between the Town of Tonawanda and any industrial, business or commercial center whereby an industrial waste of unusual strength or character may be accepted by the Town of Tonawanda for treatment, subject to payment therefor by the industrial user, for an abnormal sewage surcharge, based upon the following formula. The abnormal surcharge in dollars shall be added to any other charge computed or levied by the Town.
A. Abnormal BOD and SS sewage surcharge. Persons generating
abnormal sewage may discharge such sewage into the sanitary sewer,
provided that:
(1) The waste will not cause damage to the collection
system.
(2) The waste will not impair the treatment processes.
(3) The person discharging such wastes pays a monthly
surcharge to the Town of Tonawanda in addition to the usual monthly
sewer service charges.
(a)
Computations of such surcharges shall be based
on the following formula:
S = V x 8.34 [A (BOD-250) + B (SS-250)]
|
Where:
|
|
|
|
S

(b)
Values for A and B will be determined annually
by the Pretreatment Administrator based upon the total cost of removing
said pollutant.
B. Other abnormal waste surcharge. Persons generating
other undefined industrial wastes may discharge such waste into the
sanitary sewer, provided that:
(1) The waste will not cause damage to the collection
system.
(2) The waste will not impair the treatment processes.
(3) The person discharging said waste does not violate
any state or federal rule or regulation governing said industrial
waste.
(4) The person discharging such waste pays a monthly surcharge
to the Town of Tonawanda in addition to the usual monthly sewer service
charges. Computations of such surcharges shall be based upon the following
formula:
S (additional) = V x 8.34 [C x Y]
|
Where:
|
|
|
|
C
|
=
|
Unit charge per pound to accept said pollutant
as determined quarterly by the Pretreatment Administrator in dollars
|
|
Y
|
=
|
Pollutant or waste in parts per million by weight
|
C. Abnormal sewage surcharge: phosphate (P) and chlorine
demand (Cl). Persons generating abnormal sewage may discharge such
waste into the sanitary sewer, provided that:
(1) The waste will not cause damage to the collection
system.
(2) The waste will not impair the treatment processes.
(3) The person discharging such waste pays a monthly surcharge
to the Town of Tonawanda in addition to the usual monthly sewer service
charges.
(a)
Computations of such surcharges shall be based
on the following formula:
S = (additional) = V x 8.34 [D(P-6) + E(Cl-8)]
|
Where:
|
|
|

|
(b)
The values for D and E hereof will be determined
annually by the Pretreatment Administrator based upon the total cost
of removing said pollutant.
D. Less than normal strength index. If the strength index
for either BOD, SS, phosphates, chlorine demand or other pollutants
is less than the normal strength index for that category, then there
shall be no surcharge for that category, nor shall there be credit
given to the total surcharge.
E. Increased costs. Any person who discharges any pollutant
into the system who, in the opinion of the Pretreatment Administrator,
causes an increase in the cost of managing the waste, treating the
waste or disposing of the effluent or sludge leaving the treatment
works shall pay for these increased costs in addition to those provided
above.
Effluent limitations promulgated by the Federal Act shall apply in any instance where they are more stringent than limitations in these rules and regulations. Under Section 307 of the Federal Act, pretreatment standards are designed to achieve three purposes: to protect the operation of the publicly owned treatment works; to prevent the discharge of pollutants which pass through such works inadequately treated; and to prevent treatment plant sludges from becoming contaminated with toxic materials which would limit a publicly owned treatment works' sludge disposal alternatives. Users in industrial categories subject to effluent guidelines issued under Section 304 of the Federal Act and discharging pollutants to publicly owned treatment works are required to achieve the level of treatment established by federal regulations. Nothing in these rules and regulations shall be construed to relieve any industrial user from its obligation to comply with the pretreatment standards established pursuant to Section 307 of the Federal Act. Limitations on wastewater strength in §
165-21 hereof may be supplemented with more stringent limitations when, in the opinion of the Pretreatment Administrator:
A. Protection of treatment works. The limitations on §
165-21 hereof may not be sufficient to protect the operation of the Department's treatment works; or
B. Maintenance of effluent limitations. The limitations in §
165-21 hereof may not be sufficient to enable the Department's treatment works to comply with the water quality standards or effluent limitations specified in the state pollutant discharge elimination system (SPDES) permit.
