A.
It is one explicit purpose of these rules, regulations
and ordinances to deter, prevent and eliminate, as far as possible,
the introduction of unpolluted waters into the City of Schenectady
sanitary sewer system and all sewers tributary thereto. However, it
is recognized that in certain areas the immediate enforcement of these
rules, regulations and ordinances against existing subsurface drainage
connections would be unfeasible and unreasonable.
B.
This statement shall not be construed to mitigate
in any way the enforcement of these rules, regulations and ordinances
against the construction of any new sanitary sewers or against any
new connections discharging unpolluted waters to the City of Schenectady
sanitary sewage system, or sewers tributary thereto, or to the alleviation
of unreasonable flows of unpolluted waters; nor shall this statement
of policy be used as a reason or not making any changes which may
be ordered by governmental regulatory agencies.
No person shall discharge or cause to be discharged
any stormwater, surface water, ground water, roof runoff, subsurface
drainage, uncontaminated cooling water or unpolluted industrial process
waters to any sanitary sewer.
It shall be unlawful to discharge to any natural
outlet within the City of Schenectady or in any area under the jurisdiction
of said City any sewage or other polluted waters, except where suitable
treatment has been provided in accordance with subsequent provisions
of this Part 2.
[Amended 12-12-1988 by Ord. No. 88-91; 12-27-2010 by Ord. No. 2010-23]
Stormwater and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as combined sewers or storm sewers approved by the Director and City Engineer. Industrial cooling water or unpolluted process waters may be discharged on issuance of a permit, as described in § 220-44 of this chapter, to a storm sewer or combined sewer.
[Amended 12-12-1988 by Ord. No. 88-91; 12-27-2010 by Ord. No. 2010-23]
A.
General prohibitions. A user may not introduce, directly
or indirectly into the City POTW, any pollutant(s) or wastewater which
will pass through or cause interference with the operation or performance
of the City POTW. These general prohibitions and the specific prohibitions
below apply to each user introducing pollutants into the City POTW
whether or not the user is subject to other national pretreatment
standards or any national, state, or local pretreatment requirements.
(40 CFR § 403.5.)
B.
Specific
prohibitions.
(1)
Fire or explosion hazards.
(a)
Any liquids, solids or gases which by reason of their nature or quantity
are, or may be, sufficient either alone or by interaction with other
substances to cause fire or explosion or be injurious in any other
way to the POTW or to the operation of the POTW. At no time shall
two successive readings on an explosion hazard meter at the point
of discharge into the system (or at any point in the system) be more
than 5%, nor any single reading over 10% of the lower explosive limit
(LEL) of the meter.
(b)
Pollutants which create a fire or explosion hazard in the POTW, including,
but not limited to, waste streams with a closed cup flashpoint of
less than 140° F. or 60° C. using the test methods specified
in 40 CFR 61.21.
(2)
Solid or viscous substances which may cause obstruction
to the flow in a sewer or other interference with the operation of
the wastewater treatment facilities, such as but not limited to grease
and garbage with particles greater than 1/2 inch in any dimension.
Solid or viscous pollutants in amounts which will cause obstruction
to the flow in the POTW resulting in interference.
(3)
Other hazards.
(a)
Any wastewater or pollutants having a pH less than 5.5 or greater
than 9.5, unless a permit is specifically issued to accommodate such
wastewater, or wastewater having any other corrosive property capable
of causing damage or hazard to structures, equipment and/or personnel
of the POTW. Pollutants which will cause corrosive, structural damage
to the POTW, but in no case discharges with pH lower than 5.0, unless
the works is specifically designed to accommodate such discharges.
(b)
Any pollutant, including oxygen-demanding pollutants (BOD, etc.),
released in a discharge at a flow rate and/or pollutant concentration
which will cause interference with the POTW.
(c)
Petroleum oil, nonbiodegradable cutting oil, or products of mineral
oil origin in amounts that will cause interference or pass through.
(4)
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, to produce
toxic effect in the receiving waters of the POTW or to exceed the
limitation 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 Act.
(5)
Pollutants which result in the presence of toxic gases,
vapors, or fumes within the POTW in a quantity that may cause acute
worker health and safety problems. This shall include any noxious
or malodorous liquids, gases or solids which, either singly or by
interaction with other wastes, are sufficient to create a public nuisance
or hazard to life or are sufficient to prevent entry into the sewers
for maintenance and repair.
(6)
Any substance which may cause the POTW treatment plant
effluent or any other product of the treatment plant, such as residues,
sludges or scums, to be unsuitable for reclamation and reuse or to
interfere with the reclamation process. In no case shall a substance
discharged to the treatment plant cause the POTW to be in noncompliance
with sludge use or disposal criteria, guidelines or regulations developed
under Section 405 of the Act; any criteria, guidelines or regulations
affecting sludge use or disposal developed pursuant to the Solid Waste
Disposal Act, the Clean Air Act or the Toxic Substances Control Act:
or state criteria applicable to the sludge management method being
used.
(7)
Any substance which will cause the POTW to violate
its New York State Pollutant Discharge Elimination System permit or
the receiving water quality standards.
(8)
Any wastewater with objectionable color not removed
in the treatment process, such as but not limited to dye wastes and
vegetable tanning solutions.
(9)
Heat in amounts which will inhibit biological activity
in the POTW resulting in interference, but in no case heat in such
quantities that the temperature at the POTW treatment plant exceeds
40° C. (104° F.) unless the approval authority, upon request
of the City, approves alternate temperature limits.
(10)
Any pollutants, including oxygen demanding pollutants
(BOD, etc.) released at a flow rate and/or pollutant concentration
which a user knows or has reason to know will cause interference to
the POTW treatment plant or is in contravention of permit conditions.
(11)
Any wastewater containing any radioactive wastes
or isotopes of such half-life or concentration as may exceed limits
established by the Director in compliance with applicable state or
federal regulations.
(12)
Any water or waste containing fats, wax, grease
or oils, whether emulsified or not, or containing substances which
may solidify or become viscous at temperatures between 32º and
104º F. (0º and 40º C.)
(13)
Any garbage that has not been properly shredded.
(14)
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 the receiving
waters.
(15)
Any trucked or hauled pollutants, except at discharge points designated
by the POTW.
C.
When the Director determines that a user is contributing to the POTW any of the above-enumerated substances in such amounts as to interfere with the operation of the POTW, the Director shall advise the user of the impact of the contribution on the POTW pursuant to procedures in § 220-81 et seq. of this Part 2.
[Amended 12-12-1988 by Ord. No. 88-91]
Upon the promulgation of the Federal Categorical
Pretreatment Standards for a particular industrial subcategory, the
federal standard, if more stringent than limitations imposed under
this Part 2 for sources in that subcategory, shall immediately supersede
the limitations imposed under this Part 2. The Director shall notify
all affected users of the applicable reporting requirements under
40 CFR Part 403.12.
No person shall discharge substances directly
into a manhole or other sanitary opening in a sanitary sewer, other
than through an approved building sewer.
[Amended 12-12-1988 by Ord. No. 88-91]
No person shall discharge any holding tank waste
into a manhole or other opening in a sanitary sewer. All holding tank
waste discharged within the Schenectady POTW system shall be discharged
at a facility at locations designated by the Director. Each separate
load of holding tank waste shall be registered with the operator of
the treatment facility. The user shall pay the applicable charges
and fees and shall meet such other conditions as required by the Department.
The Department shall have the right to inquire about the type of waste,
the approximate volumes and the origin of holding tank wastes. The
transporter of such wastes shall also have a waste haulers permit
from the NYSDEC.
Where the City's wastewater treatment system
achieves consistent removal of pollutants limited by federal pretreatment
standards, the City may apply to the Approval Authority for modification
of specific limits in the federal pretreatment standards. "Consistent
removal" shall mean reduction in the amount of a pollutant or alteration
of the nature of the pollutant by the wastewater treatment system
to a less toxic or harmless state in the effluent which is achieved
by the system in 95% of the samples taken when measured according
to the procedures set forth in 40 CFR Part 403.7(c)(2), General pretreatment
regulations for existing and new sources of pollution, promulgated
pursuant to the Act. The City may then modify pollutant discharge
limits in the federal pretreatment standards if the requirements contained
in 40 CFR Part 403.7 are fulfilled and prior approval from the Approval
Authority is obtained.
[Amended 12-12-1988 by Ord. No. 88-91; 12-27-2010 by Ord. No. 2010-23]
A.
No user shall discharge wastewater to the sanitary
sewer system when any of the pollutant concentrations exceed the limits
specified herein. These concentrations shall be applied to wastewater
effluents at a point just prior to discharge into the City sewer system.
With the express written consent of the Director of Water and Wastewater,
users with multiple discharge outfalls may combine waste streams by
calculation to report on wastewater characteristics.

The City reserves the right to establish by local law more stringent limitations or requirements on discharges to the wastewater disposal system if deemed necessary to comply with the objectives presented in § 220-5 of this chapter.
No user shall ever increase the use of process
water of, 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 City or state.
No connection with or opening into any sewer,
manhole or appurtenances thereto shall be made without the written
approval of the appropriate City agency. The connection of a building
sewer into any City sewer shall conform to the requirements of the
applicable City regulations.
[Amended 12-12-1988 by Ord. No. 88-91; 12-27-2010 by Ord. No. 2010-23]
A.
Written approval by the Director is required for all new discharges from industrial users or any planned significant changes to the user’s operations or system added to the City sewer system. The Director reserves the right to deny or condition new or increased contributions of wastes or changes in wastewater constituents and characteristics, to require an industrial user to obtain an industrial wastewater discharge permit as specified in § 220-44, to require the development of a schedule of compliance for an industrial user for the installation of technology required to meet pretreatment standards and requirements and/or to require the industrial user to submit to the Department self-monitoring reports. Any industrial facility expansion, production increase, or other modifications which result in new, different, or increased discharges of pollutants must be reported to the Department at least 90 days prior to any such discharge.
B.
Industrial
users required to obtain an industrial waste discharge permit shall
complete and file with the Department an application in the form prescribed
by the City at least 90 days prior to connecting to or contributing
to the City. In support of the application, the user may be required
to submit, in units and terms appropriate for evaluation, the following
information:
(1)
A
description of all activities, facilities and plant processes directly
related to sewer discharges. This description shall include all those
materials which are or could reasonably be expected to be discharged,
including hazardous materials as defined by regulations promulgated
under the federal Resource Conservation and Recovery Act (42 U.S.C. § 6901).
[Added 12-27-2010 by Ord. No. 2010-23]
A.
Septic tank waste may be introduced into the POTW only at locations designated by the City, and at such times as are established by the City. Such waste shall not violate § 220-32 or any other requirements established by the City. The City may require septic tank waste haulers to obtain wastewater discharge permits.
B.
Haulers of industrial wastes shall obtain wastewater discharge permits.
The City may require generators of hauled industrial waste to obtain
wastewater discharge permits. The City also may prohibit the disposal
of hauled industrial waste. The discharge of hauled industrial waste
is subject to all other requirements of this part.
C.
Industrial waste haulers may discharge loads only at locations designated
by the City. No load may be discharged without prior consent of the
City. The City may collect samples of each hauled load to ensure compliance
with applicable standards. The City may require the industrial waste
hauler to provide a waste analysis of any load prior to discharge.
D.
Industrial waste haulers must provide a waste-tracking form for every
load. This form shall include, at a minimum, the name and address
of the industrial waste hauler, permit number, truck identification,
names and addresses of sources of waste, and volume and characteristics
of waste. The form shall identify the type of industry, known or suspected
waste constituents, and whether any wastes are RCRA hazardous wastes.
[Added 12-27-2010 by Ord. No. 2010-23]
A.
Any user who commences the discharge of hazardous waste shall notify the POTW, the EPA Regional Waste Management Division Director, and state hazardous waste authorities, in writing, of any discharge into the POTW of a substance which, if otherwise disposed of, would be a hazardous waste under 40 CFR Part 261. Such notification must include the name of the hazardous waste as set forth in 40 CFR Part 261, the EPA hazardous waste number, and the type of discharge (continuous, batch, or other). If the user discharges more than 100 kilograms of such waste per calendar month to the POTW, the notification also shall contain the following information to the extent such information is known and readily available to the user: an identification of the hazardous constituents contained in the wastes, an estimation of the mass and concentration of such constituents in the waste stream discharged during that calendar month, and an estimation of the mass of constituents in the waste stream expected to be discharged during the following 12 months. All notifications must take place no later than 180 days after the discharge commences. Any notification under this Subsection need be submitted only once for each hazardous waste discharged. However, notifications of changed conditions must be submitted under § 220-42. The notification requirement in this section does not apply to pollutants already reported by users subject to categorical pretreatment standards under the self-monitoring requirements of § 220-46M.
B.
An existing user must submit the above notification no later than
at the time it submits its next renewal application after the effective
date of this provision.
C.
Dischargers are exempt from the requirements of Subsection A of § 220-42.2, above during a calendar month in which they discharge no more than 15 kilograms of hazardous wastes, unless the wastes are acute hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(c). Discharge of more than 15 kilograms of nonacute hazardous wastes in a calendar month, or of any quantity of acute hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(c), requires a one-time notification. Subsequent months during which the user discharges more than such quantities of any hazardous waste do not require additional notification.
D.
In the case of any new regulations under Section 3001 of RCRA identifying
additional characteristics of hazardous waste or listing any additional
substance as a hazardous waste, the user must notify the City, the
EPA Regional Waste Management Waste Division Director, and state hazardous
waste authorities of the discharge of such substance within 90 days
of the effective date of such regulations.
E.
In the case of any notification made under this section, the user
shall certify that it has a program in place to reduce the volume
and toxicity of hazardous wastes generated to the degree it has determined
to be economically practical.
F.
This provision does not create a right to discharge any substance
not otherwise permitted to be discharged by this part, a permit issued
thereunder, or any applicable federal or state law.
