[Amended 1-26-2012 by Res. No. 12-01-003]
A. Regular surcharge:
(1) Whenever the Authority consents to accept industrial waste into the
sewer system which has total suspended solids (SS) in excess of 250
milligrams per liter (mg/l), total biochemical oxygen demand (BOD)
in excess of 250 milligrams per liter, total phosphorous (TP) in excess
of 12 mg/l, and/or total nitrogen (TN) in excess of 40 mg/l, the following
surcharge shall be applicable for BOD in excess of 250 mg/l, SS in
excess of 250 mg/l, TP in excess of 12 mg/l, and/or TN in excess of
40 mg/l.
(2) The surcharge shall be computed in accordance with the following
formulas:

(b)
Calculation of cost per pound for BOD, SS, TP, and/or TN treatment.
Refer to Appendix BE for the calculation of the yearly audited operating
cost directly related to the treatment of BOD, SS, TP, and/or TN.
The rate will be subject to yearly adjustment based upon the audited
yearly cost of operation for the previous fiscal year ending March
31. This adjustment will take effect with the acceptance and approval
by the Board for the Authority, of the fiscal year ending audit as
prepared by the Authority's auditors, in the month that it is approved.

B. Additional surcharge calculation:
(1) Whenever the Authority consents to accept industrial waste into the
sewer system which has total suspended solids in excess of 2,000 mg/l
and/or total biochemical oxygen demand in excess of 2,000 mg/l, an
additional surcharge will be applied. The additional surcharge will
be computed as follows:
|
R
|
=
|
(A x 0.000001) x (S) x 8.34
|
|
T
|
=
|
R x J x 3
|
|
U
|
=
|
(A x 0.000001) x (V) x 8.34 W = U x K x 3
|
|
Where:
|
|
A
|
=
|
Discharge gallons per month
|
|
R
|
=
|
Additional pounds BOD
|
|
S
|
=
|
Reported BOD—2,000
|
|
T
|
=
|
Additional surcharge for BOD
|
|
U
|
=
|
Additional pounds SS
|
|
V
|
=
|
Reported SS — 2,000
|
|
W
|
=
|
Additional surcharge for SS
|
(2) The additional surcharge will be added to the normal surcharge to
arrive at the total industrial waste surcharge bill.
C. Measurement of concentration of wastewater:
(1) Wastewater being discharged into the sewer system shall be subject
to sampling and inspection to be used as a basis for determining the
surcharge due to excessive concentrations of BOD, total suspended
solids, total phosphorous, and/or total nitrogen, and also as a basis
for evaluating compliance with any other Authority rule, regulation,
permit condition, pretreatment requirement, prohibited discharge or
any EPA or DEP pretreatment standard or pretreatment requirement.
All measurements, tests and analyses of the characteristics of wastewater,
including sewage and industrial wastewater, shall be determined by
a laboratory that the Authority determines is qualified to perform
such measurements, tests and analyses.
(2) The cost of all sampling and testing shall be borne by the respective
user. Refer to Appendix BG for the schedule of rates, charges, and
fees for sampling and testing of wastewater.
(3) For the purpose of determining strength of waste surcharge, the user
may request that multiple samples be taken for a given billing period.
The cost of taking these samples and making the analyses shall be
borne by the user. Whenever multiple samples are obtained during a
given billing period, the concentrations for BOD, total suspended
solids, total phosphorous, and total nitrogen shall be totaled and
divided by the number of samples taken to derive an average for each.
These averages will then be utilized in the computation of the strength
of waste surcharge for that billing period.
If use or classification of any property should
change within a month, the difference in sewer rental, prorated on
a monthly basis, will be charged or credited, as the case may be,
on the bill for the succeeding month. Additional classifications and
additional sewer rentals may be established by the Authority from
time to time.
Sewer rentals or charges shall be paid monthly/quarterly.
All bills shall be due and payable not later than the 25th of the
month for and in which the bill was rendered. Owners shall be subject
to all applicable sewer rentals and charges when connection is made
to the sewer system. This section shall become effective and be in
force as of April 1, 2006.
