1. Although the sewage treatment works will be capable of treating certain industrial wastes, the actual treatment of such wastes may increase the cost of operating and maintaining the public sanitary sewage system. Therefore, there will be imposed upon each person discharging such industrial waste into public sanitary sewage system a surcharge, or surcharges which are intended to cover such additional costs. Such surcharges shall be in addition to regular sewage service surcharges and shall be payable as herein provided.
2. Determination of Surcharges. The strength of any industrial/commercial waste discharge which is to be subject to surcharge as determined by subsection .3 of this Section, shall be determined quarterly, or more frequently as the Borough shall determine, from samples taken either at the manhole or metering chamber referred to in this Part, or at any other sampling point mutually agreed upon by the Borough and the producer of such waste. The frequency and duration of the sampling period shall be such as, in the opinion of the Borough, will permit a reasonably reliable determination of the average composition of such waste, exclusive of stormwater runoff. Samples shall be collected by the Borough, or their collection supervised by the Borough and shall reasonably reflect the characteristics of the waste over a 24-hour period, exclusive of stormwater runoff. Except as hereinafter provided, the strength of the waste so found by analysis shall be used for establishing the surcharge or surcharges. However, the Borough may, if it so elects, accept the results of routine sampling and analyses by the producer of such wastes in lieu of making its own sampling and analyses.
3. Calculation of Surcharges. In the event that, after sampling and analysis as prescribed in subsection .2 hereof, any industrial waste is found by the Borough to have pollutants of BOD concentration in excess of 204 milligrams per liter and/or non-filterable residue concentration in excess of 240 milligrams per liter, the producer of said waste shall pay a strength of waste surcharge in addition to the regular sewage service charge, which surcharge shall be computed by using the following industrial waste surcharge formula:
SQ = 0.00834QI[(BODI - 204)TA + (SSI - 204)TB]
A. Where:
(1) SQ is the quarterly surcharge to be added to the basic user charge.
(2) 0.00834 is a constant to convert waste concentrations expressed in million gallons.
(3) QI is the quarterly industrial/commercial waste flow expressed in million gallons.
(4) BODI and SSI are the respective concentrations of BOD5 and suspended solids of the industrial waste expressed in mg/l.
(5) 204 is a constant which expresses the waste load concentrations of BOD and suspended solids for normal domestic wastes in mg/l.
(6) TA and TB are actual treatment costs incurred by the Borough per 1,000 pounds of BOD and suspended solids, respectively. These costs are determined annually by the Borough based upon actual costs of operation and maintenance.
When a value of BOD and/or suspended solids is less than the maximum allowable concentration set forth in the industrial waste surcharge formula, then the maximum allowable concentration shall be used in the calculation of the industrial waste surcharge.
5. Sampling Fees and Schedules. All industrial users requiring an industrial/commercial waste discharge permit will be assessed a fee or service charge for each scheduled sampling to be performed by the Borough. The charge to the industrial/commercial user for each scheduled sampling will be set by the Borough. This fee will be in addition to the costs of analysis for which the indus trial/commercial user will reimburse the Borough.
