All nonresidential persons discharging or depositing
wastes into the public sewers shall pay a sewer service charge proportional
to the liquid volume of waste so deposited, which charge shall be
collected as a sewer rent. Residential sewer service charges are determined
by the Town of Seneca Falls (Board) and are based upon metered water
consumption.
All persons discharging or depositing wastes
with concentrations in excess of the pollutant concentrations in normal
sewage shall pay a surcharge.
The total sewer service charge (which shall
be called the "user charge") is comprised of two parts, as follows:
|
UC(t) = UC(n) + UC(an)

that is, the difference shall be set to zero when it is negative.

The service area of the POTW may be segmented
to assist in a fair distribution of user charges, especially if there
is a pump station serving a segment.
The volume of flow to be used in computing sewer
service charges and abnormal sewage surcharges shall be based upon
metered water consumption as shown on the records of meter readings
maintained by the Town of Seneca Falls Water Department. In the event
that a person discharging wastes into the POTW produces evidence to
the Superintendent demonstrating that a substantial portion of the
total amount of metered water does not reach the POTW, then the Superintendent
shall either establish a percentage of the total metered water to
be used as a basis for such computations or direct the installation
of appropriate flow-measuring (and totalizing) devices to measure
and record the actual amount of flow into the POTW. In the event that
a person discharging wastes into the POTW procures all or part of
his water supply from unmetered sources, the Superintendent shall
either direct the installation of water meters on the other sources
of water supply or direct the installation of appropriate flow-measuring
devices to measure and record the actual amount of flow into the POTW.
Any water meters and/or flow-measuring devices installed pursuant
to this section shall be of a type and design acceptable to the Superintendent
and shall be installed, maintained and periodically tested as required
by the Superintendent, at the owner's expense. All such meters and/or
flow-measuring devices shall be subject to periodic inspection, testing
and reading by the Superintendent. Any person discharging wastes into
the POTW may install a flow-measuring device at his or her option,
of the type, design, installation and maintenance standards of the
Superintendent, at the owner's expense.
The billing period shall be monthly for industrial
users and bimonthly for nonindustrial users.
The additional charges and fees associated with
the operation of the pretreatment program shall be assessed to the
user and include:
A.
Reimbursement of costs of setting up and operating
the pretreatment program.
B.
Issuing permits.
C.
Monitoring, inspections and surveillance procedures.
D.
Costs of equipment and supplies.
E.
Reviewing accidental discharge procedures.
F.
Construction inspections.
G.
Filing appeals.
H.
Application for consistent removal status as outlined
in 40 CFR 403.
I.
Other reasonable expenses to carry out the program
to satisfy the requirements of this Part 2, the NYSDEC and the federal
government.
The charge for treatment and disposal of trucked
or hauled waste which has been introduced into the POTW shall be as
established by the Town Board. The manner of determining the volume
dumped shall be at the discretion of the Superintendent.
The Town of Seneca Falls may institute an equitable
procedure for recovering the costs of any capital improvements of
those parts of the POTW which collect, pump, treat and dispose of
industrial wastewaters from those persons discharging such wastewaters
into the POTW.
The POTW shall be operated on the basis of a
fiscal year commencing on the first day of January and ending on the
31st day of December.
The Town of Seneca Falls (Board) shall have
the authority to impose impact fees on new development, which development
may:
Revenues derived from user charges and associated
penalties and impact fees shall be credited to a special fund. Moneys
in this fund shall be used exclusively for the following functions:
A.
For the payment of the operation and maintenance,
including repair and replacement costs, of the Town of Seneca Falls
POTW.
B.
For the discovery and correction of inflow and infiltration.
C.
For the payment of interest on and the amortization
of or payment of indebtedness which has been or shall be incurred
for the construction or extension of the Town of Seneca Falls POTW.
D.
For the extension, enlargement, replacement of and/or
additions to the Town of Seneca Falls POTW, including any necessary
appurtenances.
A.
The Town of Seneca Falls shall maintain and keep proper
books of records and accounts for the POTW, separate from all other
records and accounts, in which shall be made full and correct entries
of all transactions relating to the POTW. The Town of Seneca Falls
will cause an annual audit of such books of record and account for
the preceding fiscal year to be made by a recognized independent certified
public accountant and will supply such audit report to authorized
officials and the public on request.
B.
In conjunction with the audit, there shall be an annual
review of the sewer charge system to determine if it is adequate to
meet expenditures for all programs for the coming year.
C.
Classification of old and new industrial users should
also be reviewed annually.
D.
The Town of Seneca Falls shall maintain and carry
insurance on all physical properties of the POTW, of the kinds and
in the amounts normally carried by public utility companies and municipalities
engaged in the operation of sewage disposal systems. All moneys received
for losses under any such insurance policies shall be applied solely
to the replacement and restoration of the property damaged or destroyed.
