It is the purpose of this section to provide for the recovery
of costs related to the POTW from all dischargers to the Borough's
POTW. The applicable charges or fees shall be set forth in the Borough's
schedule of charges and fees which may be adopted by either ordinance
or resolution of the Borough Council.
[Amended 9-15-2010 by Ord. No. 1796; 12-21-2011 by Ord. No. 1816]
A. Sewer rates, charges and fees may be established and changed from
time to time by resolution of the Borough Council and include, without
limitation:
(1) Fees for reimbursement of costs for construction and operation of
the POTW, as well as fees for setting up and operating the Borough's
pretreatment program.
(3) Fees for monitoring, inspections, and surveillance procedures.
(4) Fees for reviewing accidental discharge procedures and construction.
(5) Fees for permit applications.
(6) Fees for filing and conducting appeals.
(7) Fees for consistent removal by the Borough of pollutants otherwise
subject to federal pretreatment standards.
(8) Fees for the various discharges into the POTW, including special
fees for certain waste streams as deemed appropriate by the Borough.
(9) Other fees the Borough may deem necessary to carry out the requirements
contained herein.
B. Strength surcharge.
(1) A user, with the permission of the Borough, may discharge wastewater
to the Borough's wastewater treatment plant (WWTP) having concentrations
of five-day biochemical oxygen demand (BOD
5), total suspended solids (TSS), ammonia-nitrogen (NH
3-N) and total phosphorus (TP) in excess of the average concentration of these pollutants in domestic sewage (hereafter referred to as "high-strength wastewater") in accordance with this §
323-19. For purposes of this section, domestic sewage shall be considered as having the following concentrations:
(2) Notwithstanding the above, the discharge of high-strength wastewater shall be prohibited, or the program will be amended, if deemed advisable by the Borough, if the discharge violates or has the potential to violate Article
II of this Chapter
323 (referring to narrative or numeric prohibitions on discharges); in the event that the Borough's WWTP is or has the potential to be in violation of its NPDES permit limits; the Borough's WWTP receives new, stricter NPDES permit limits; or in the event that the Borough's WWTP is or has the potential to become organically overloaded.
(3) There shall be additional charges imposed by the Borough for the
treatment of high-strength wastewater discharged by a user (hereafter
"surcharges").
(a)
These surcharges shall be calculated using the following formulas:
|
SQ1 = 8.34 x Qd x {(DBOD5 - 230) x TCBOD5} —
Additional charge for BOD5 treatment;
|
|
SQ2 = 8.34 x Qd x {(DTSS - 200) x TCTSS} —
Additional charge for TSS treatment;
|
|
SQ3 = 8.34 x Qd x {(DNH3N - 25) x TCNH3N} —
Additional charge for NH3-N treatment;
|
|
SQ4 = 8.34 x Qd x {(DTP - 10) x TCTP} —
Additional charge for TP treatment.
|
|
SQT = SQ1 + SQ2 + SQ3 + SQ4;
|
(b)
The following shall apply to the formulas set forth hereinabove:
[1]
"SQT" is the surcharge. The surcharge
shall be assessed in addition to the user's basic sewer bill. The
normal billing period shall be quarterly, unless a different billing
period is identified by the Borough in writing (quarterly surcharge
billing periods shall coincide with quarterly water use billing periods).
The surcharge shall be based on the total pounds of BOD5, TSS, NH3-N and TP, greater
than that of domestic sewage, discharged by the user during the billing
period.
[2]
"8.34" is a constant to convert concentrations expressed in
mg/l to pounds.
[3]
"Qd" is the total wastewater flow for the user, expressed in
millions of gallons. This value shall be calculated based on the total
water use at the facility for the billing period, unless the user
can provide, to the satisfaction of the Borough, an accurate measurement
of the total wastewater flow from a properly designed, installed,
operated and maintained flow meter. Flow meter calibration records
shall be provided to the Borough upon request. Flow measurements from
deduct meters will be considered on a case-by-case basis, and their
use in the surcharge calculations will be at the sole discretion of
the Borough.
[4]
"DBOD5," "DTSS," "DNH3N" and "DTP" are the respective average concentrations of BOD5, TSS, NH3-N and TP in the user's
wastewater, expressed in mg/l, for the billing period. These values
will be determined by periodic sampling of the user's wastewater and
the completion of laboratory analyses on the wastewater samples. Samples
will be collected and analyzed in accordance with state and federal
requirements and at a frequency determined by the Borough to be appropriate
to properly characterize the quality of the user's wastewater. The
results of analyses on all samples, resamples, and split samples obtained
by the Borough or user for the billing period shall be included in
such average to determine DBOD5, DTSS, DNH3N and DTP. Results from samples which were not collected
or analyzed following state and federal protocols will not be considered.
The user shall be responsible for all costs of sampling and analyses
associated with the calculation of high-strength wastewater surcharges.
[5]
"230," "200," "25" and "10" are constants which express the
waste concentrations for the respective constituents, in mg/l, contained
in domestic sewage.
[6]
A dollar-per-pound treatment cost will be determined by the
Borough for every pound of BOD5 TSS, NH3-N and TP removed at the wastewater treatment plant
on an annual basis. Annual operating, administrative, general, capital
and/or debt service costs may be considered by the Borough in its
determination of the dollar-per-pound treatment costs for these four
parameters. The total annual treatment costs identified for each of
these four parameters will be divided by the total pounds of each
of these four parameters removed at the wastewater treatment plant
to calculate the corresponding dollar-per-pound treatment costs. Dollar-per-pound
treatment costs for these four parameters will be updated in annual
intervals deemed appropriate by the Borough.
[7]
"TCBOD5" is the dollar-per-pound treatment
cost calculated by the Borough for BOD5.
[8]
"TCTSS" is the dollar-per-pound treatment
cost calculated by the Borough for TSS.
[9]
"TCNH3-N" is the dollar-per-pound treatment
cost calculated by the Borough for NH3-N.
[10] "TCTP" is the dollar-per-pound
treatment cost calculated by the Borough for TP.
[11] In the event that a user's wastewater concentration
contained in a sample or samples used for purposes of calculating
the billing period average concentration of BOD
5, TSS, NH
3-N and/or TP is less than the domestic sewage concentration(s) values set forth in Subsection
B(3)(b)[5] above, then the domestic sewage concentration(s) values set forth in Subsection
B(3)(b)[5] above shall be used.
