[Ord. 1073, 11/8/2007, § 14.1]
1.
Purpose. Nothing contained in this section shall be construed as prohibiting any special agreement or arrangement between the City and any person or municipality whereby industrial waste of unusual strength or character may be admitted into the sewerage system by the City; provided, that such agreement does not violate any National Pretreatment Standards or local limits, and subject to payment of a surcharge therefore by such person or municipality or by proper and continuous pretreatment prior to discharge into the sewerage system. The surcharge shall be based on present invested costs and operating costs. The City may impose mass limitation, concentration limits based on mass proportion or selected industrial reductions methods in allocating the maximum pollutant loading to the wastewater treatment plant. In accordance with § 18-407, changes to local limits must be submitted to the approval authority for approval.
2.
Additional Charges for Strong Wastes. There shall be additional charges
for nondomestic wastes, discharged to the POTW from any industry,
business or commercial enterprise and having BOD5, TSS, and/or NH3-N in excess of the average
BOD5, TSS, and/or NH3-N of normal domestic sewage. Normal domestic sewage shall be defined
as having the following concentrations:
3.
Surcharge Formula. In order to determine the additional charge for
non-domestic wastes with strength greater than that of normal domestic
sewage, the following formula shall be used:
|
Q = 0.00834 QI [(BOD5 - 300) TA + (TSSI
- 325) TB + (NH3 - NI - 20) TC]
|
|
Where:
| ||
|
SQ is the quarterly surcharge to be added to the quarterly sewer
rental charge.
| ||
|
0.00834 is a constant to convert waste strength expressed in
mg/L to thousand pounds of waste.
| ||
|
QI is the quarterly volume of nondomestic wastewater flow expressed
in millions of gallons.
| ||
|
BOD5 is the five-day biochemical oxygen
demand of the nondomestic wastewater expressed in mg/L.
| ||
|
TSSI is the total suspended solids in mg/L of the nondomestic
wastewater.
| ||
|
NH3-NI is the ammonia, expressed as nitrogen
in mg/L of the nondomestic wastewater.
| ||
|
300, 325 and 20 are constants expressing wasteload strength
of domestic waste in mg/L for the respective pollutant parameters.
TA represents the cost incurred by the City in treating 1,000 pounds
of BOD5. TB represents the cost of treating
1,000 pounds of total suspended solids. TC represents the cost incurred
by the City in treating 1,000 pounds of ammonia. TA, TB and TC vary
each year as treatment plant operation and maintenance costs change.
Therefore, TA and TB and TC shall be determined at the beginning of
each calendar year by the City based upon budgeted operating costs,
and adopted by resolution by the City.
| ||
|
When a value of BOD5 and/or total suspended
solids and/or ammonia of a nondomestic waste is less than 300, 325,
and 20 mg/L respectively, the value of 300, 325, and 20 mg/L respectively
shall be used in the calculation of the strong waste discharge in
place of the actual value which is less than 300, 325, and 20 mg/L,
respectively.

[Ord. 1073, 11/8/2007, § 14.2]
1.
Septage haulers or any other person disposing of sanitary or other
waste into the sewage system of the City at designated points as herein
provided shall pay a dumping fee to include the following charges:
A.
Testing fee for each and every delivery to the City of Reading's
wastewater treatment system.
B.
Per gallon treatment charge based on the rated capacity of the waste
delivery vehicle.
C.
Per gallon surcharge based on the rate capacity of the waste delivery
vehicle as payment for excessive BOD5, total
suspended solids, and total dissolved solids common to septic waste.
2.
The rates shall be revised annually at the beginning of each year
by the City through resolution.
