A.
No person shall discharge wastes, directly or indirectly,
into the City sewer system or into any private sewer drain emptying
into the City sewer system which cause, threaten to cause or are capable
of causing, either alone or by interaction with other substances.
(1)
Any liquids, solids or gases which, by reason of their
nature or quantity, are or may be sufficient, either alone or by interaction

in any other way to the treatment works or to the operation of the
treatment works, including but not limited to waste streams with a
closed-cup flashpoint of less than 140º F. (60º C.), using
the test methods specified in 40 CFR 261.21. 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 shall any single reading be over 10% of the lower explosive
limit (LEL) of the meter. Prohibited materials include but are not
limited to gasoline, kerosene, naphtha, benzene, toluene, xylene,
ethers, alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates,
bromates, carbides, hydrides and sulfides and any other substance

[Amended 1-5-2009 by L.L. No. 1-2009]
A.
Only generators and haulers who have obtained a permit
from the City shall be allowed to discharge trucked or hauled pollutants
at the wastewater treatment plant.
(1)
The terms and conditions of the foregoing permit shall reflect the standard operating procedure for acceptance of hauled waste at the City's wastewater treatment plant that has been approved by the United States Environmental Protection Agency. Except as modified herein, the limitations referenced in § 253-68 shall also apply to the discharge of hauled waste at the wastewater treatment plant.
(2)
Notwithstanding anything in this section to the contrary, a generator of hauled waste that is considered holding tank waste, as defined in § 253-23B, shall be allowed to discharge at the wastewater treatment plant, provided it uses a hauler who has been permitted under this section and 6 NYCRR Part 364 and it seeks to discharge only holding tank waste that can be accepted at the wastewater treatment plant in compliance with all applicable federal, state and local laws, rules, ordinances and regulations, including requirements associated with the SPDES permit held by the City for the discharge of treated wastewater from the treatment plant ("applicable law"). Although no separate generator's permit shall be required for the discharge of holding tank waste, the generator of such waste shall be responsible, in addition to the hauler, for offering for discharge only holding tank waste that can be accepted at the wastewater treatment plant in accordance with applicable law.
B.
Hauled waste with analytical sample data meeting the hauled waste effluent limitations set forth in § 253-29 (total) and holding tank waste authorized for discharge under the Code shall be discharged either at the tanker dump port at Influent A headworks or the gravity thickeners depending upon the percentage of solids in the hauled waste. The discharge points and guidance for placement of the hauled waste based on the percentage of solids are shown on the City of Watertown POTW Wastewater Flow Diagram,[1] a copy of which is attached.
[1]
Editor's Note: Said diagram is on file in
the City offices.
C.
Should analyses indicate that the hauled waste contains materials that would exceed any of the "24-Hour Allowable Effluent Concentration" limits listed at § 253-29 (that is, the hauled waste effluent limitations), the tanker will not be allowed to discharge at the headworks of the wastewater treatment plant.
D.
Should analyses (total) indicate that the hauled waste
contains metals that would exceed any of the hauled waste effluent
limitations, but the dissolved component of the elevated analyte(s)
would not, the tanker may discharge the hauled waste either before
or after the gravity thickeners on the sludge handling side of the
wastewater treatment plant, as shown on the City of Watertown POTW
Wastewater Flow Diagram, a copy of which is attached.[2] For the purposes of this section, the "dissolved component"
of the analyte is defined as the concentration of analyte in an aqueous
sample that will pass through a 0.45 micron membrane filter assembly
prior to sample acidification.
[2]
Editor's Note: Said diagram is on file in
the City offices.
E.
Hauled waste that does not qualify for discharge under either § 253-28B or § 253-28C is prohibited from being discharged at the wastewater treatment plant until such time that it can be demonstrated through analytical results that the characteristics of the hauled waste have been modified by pretreatment or process or material change so as to qualify for discharge under § 253-28.
F.
At a frequency of no less than once per calendar year,
a representative sample randomly selected by the City that has been
taken from each of the trucked or hauled loads originating from a
permitted generator delivered to the wastewater treatment plant shall
be submitted by the City for additional analysis at the hauler's expense
to confirm that the hauled waste meets all the conditions of the applicable
permit(s).
(1)
In the event that testing of the hauled waste indicates
that its discharge at the wastewater treatment plant would violate
a term of a generator's or hauler's permit, the control authority:
(a)
Shall withhold permission to discharge the hauled
waste being tested until it receives the results of testing and/or
other documentation, showing that the proposed discharge will meet
all the conditions of the applicable permit(s); and
(b)
May, in addition to any other remedies available
under applicable law, revoke the permit(s) to discharge the hauled
waste to the wastewater treatment plant.
(2)
The hauler and the generator of the hauled waste shall
be jointly and severally responsible to reimburse the City for any
damages that the City incurs for a discharge of hauled waste that
violates the conditions of a permit authorizing the discharge at the
wastewater treatment plant.
G.
Fees for the acceptance of hauled waste for treatment
at the wastewater treatment plant shall be as follows:
[Amended 6-16-2014 by L.L. No. 1-2014; 6-19-2017 by L.L. No. 4-2017]
(1)
Five and one-half cents ($0.055) per gallon for hauled
waste less than or equal to 5.6% solids by weight.
(2)
For all leachate: five and one-half cents ($0.055)
per gallon.
(3)
Twelve cents ($0.12) per pound (dry weight) for hauled
waste over 5.6% solids by weight.
(4)
Minimum charge of $39.29 per delivery.
H.
Permit fees.
(2)
The payment for the first term shall be due and payable
at the time of permit application and payment for subsequent terms
shall be due and payable 30 days prior to the end of the prior term.
At the discretion of the control authority, the fee for a hauler's
permit may be waived if the applicant for the hauler's permit has,
or will have, prior to discharge of the hauled waste, a valid generator
permit that covers the waste that is the subject of the hauler's permit
application, and is not in arrears for payment of the applicable generator
permit fee.
[Amended 1-5-2009 by L.L. No. 1-2009]
The concentration in wastewater discharged into
the City sanitary sewer system of any of the following pollutants,
when averaged over a thirty-day period, shall not exceed the values
specified below. The thirty-day average concentrations shall be computed
using at least four individual twenty-four-hour composite samples
taken during a thirty-day period. In addition, the concentration of
any single twenty-four-hour composite sample shall not exceed three
times the thirty-day average. These limitations shall apply to each
and every individual industrial sewer lateral at a point immediately
prior to discharge to the City sanitary sewer system.

No person shall discharge or permit the discharge or infiltration into the City sewer system of the following wastes unless prior written approval is granted by the City Engineer, subject to the limitations and requirements of § 253-31 of this Part 3:
A.
Wastes containing more than 300 milligrams per liter
of BOD.
[Amended 4-18-1994]
B.
Wastes containing more than 350 milligrams per liter
of total suspended solids.[1]
[1]
Editor's Note: Former Subsection C, which
immediately followed this subsection and restricted wastes containing
phosphorus, was deleted 4-18-1994. Said ordinance also relettered
former Subsection D as Subsection C.
C.
Wastes containing more than 40 milligrams per liter
of total Kjeldahl nitrogen.
A.
Effluent limitations promulgated by the Federal Act shall apply in any instance where they are more stringent than limitations in this Part 3. 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 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 public owned treatment works to 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.
B.
Nothing in this Part 3 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 §§ 253-29 and 253-30 of this Part 3 may be supplemented with more stringent limitations when, in the opinion of the City Engineer:
(2)
The limitations in §§ 253-29 and 253-30 of this Part 3 may not be sufficient to enable the Department's treatment works to comply with the water quality standards or effluent limitations specified in the Department's National Pollutant Discharge Elimination System (NPDES) permit or State Pollutant Discharge Elimination System (SPDES) permit.
C.
All industrial users, whether permitted in accordance with Article VIII of this chapter or not, shall provide written notice to the City Engineer of any discharge that would otherwise be considered hazardous waste under 40 CFR 261 if disposed of in any manner other than to the City's POTW, consistent with requirements of notice contained within 40 CFR 403.12(p).
[Added 3-20-1995 by L.L. No. 2-1995]
No discharger into the City sewer system shall
augment his use of process water or otherwise intentionally dilute
his discharge as a partial or complete substitute for adequate treatment
to achieve compliance with any effluent limitations specified in this
Part 3.
Waste not permitted to be discharged into the
City sewer system must be transported in accordance with Federal Resource
Conservation and Recovery Act regulations to a state or federally
approved waste disposal site.
No connection with or opening into any sewer,
manhole or appurtenances thereto shall be made without the written
approval of the City Engineer. The connection of a building sewer
into any City sewer shall conform to the requirements of the Department
and Administration Rules and Regulations Governing Plumbing Installations.
[Amended 3-20-1995 by L.L. No. 2-1995]
Prior written approval by the City Engineer
is required for all new discharges, increased contributions of wastes
or changes in waste characteristics to the City's sewer system. The
City Engineer reserves the right to deny or condition new or increased
contributions of wastes or changes in waste characteristics.
