Note: If any difference terms in the equation above is negative,
then that portion of the equation shall not be used; that is, the
difference shall be set to zero when it is negative.
|
Note: All averages are arithmetic averages determined from available
data during the billing period.

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
Mount Morris 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 option, of the type, design,
installation, and maintenance standards of the Superintendent, at
the owner's expense.
The billing period for the debt retirement charge shall be annually,
in January of each year. The billing period for the user charge shall
be quarterly.
The additional charges and fees associated with the operation
of the pretreatment program shall be assessed the user, and include:
A. Reimbursement of costs of setting up and operating the pretreatment
program.
C. Monitoring, inspections, and surveillance procedures.
D. Costs of equipment and supplies.
E. Reviewing accidental discharge procedures.
F. Construction inspections.
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 chapter, the NYSDEC, and the federal government.
The Town of Mount Morris Sewer Use Law does not have provisions
for accepting trucked and hauled septage.
The Town of Mount Morris 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 waste from
those persons discharging such wastewaters into the POTW.
Provisions of Article
XI of this chapter relating to the collection of penalties shall apply to the collection of sewer service charges and abnormal sewage service surcharges.
The POTW shall be operated on the basis of a calendar year commencing
on the first day of January and ending on the 31st day of December.
The Town of Mount Morris Board shall have the authority to impose
impact fees on new development, which development may:
A. Cause enlargement of the service area of the POTW.
B. Cause increased hydraulic and/or treatment demands on the POTW.
Revenues derived from user charges and associated penalties
and impact fees shall be credited to a special fund. Monies 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 Mount Morris 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 Mount Morris POTW; and
D. For the extension, enlargement, replacement of, and/or additions
to the Town of Mount Morris POTW, including any necessary appurtenances.
