1. Each industrial user's share of the applicable Federal grant amount is based on that proportion of the design capacity represented by such user's discharge. The annual ICR charge shall be computed by the following formula. For charges applicable to periods of less than 1 year, all references to "annual" or "year" shall be understood to mean the appropriate period of time:
ICRC = K(Q-QD) x cq + (BOD5-BOD5D) x cBOD5 + (SS-SSD) x css + (N-ND) x cn where,
ICRC = Cost to be recovered from an industrial user per year.
K= 1.0 or less depending on conditions defined in subsection (4).
Q= Gallons of wastewater flow contributed by the user during the year, if K = 1.0, gallons of metered water consumption if K is less than 1.0.
QD = Gallons of wastewater flow that is certified as domestic waste contributed by the user during the year.
cq = The charge for Federal grant costs allocable to hydraulic capacity in dollars per thousand gallons.
BOD5 The pounds of 5 day biochemical oxygen demand contributed by a user during the year.
BOD5D = The pounds of 5 day biochemical oxygen demand contributed by the domestic waste component of a user's wastestream during the year.
cBOD5 = The charge for Federal grant costs allocable to BOD5 removal in dollars per pound.
SS = The pounds of suspended solids contributed by a user during the year.
SSD = The pounds of suspended solids contributed by the domestic waste component of a user's waste stream during the year.
css = The charge for Federal grant costs allocable to suspended solids removal in dollars per pound.
N = The pounds of total Kjeldahl nitrogen contributed by a user during the year.
ND = The pounds of total Kjeldahl nitrogen contributed by the domestic waste component of a user's waste stream during the year.
cn = The charge for Federal grant costs allocable to nitrification in dollars per pound of total Kjeldahl nitrogen.
2. The applicable charges are:
cq = $0.00805 per thousand gallons.
cBOD5 = $0.00407 per pound.
css = $0.00356 per pound.
cn = $0.03590 per pound.
3. The average daily wastewater flow and pollutant poundage due to the domestic wastes shall be computed for each industrial user by multiplying the average number 40 hour per week employees times 35 gallons per day per employ and assuming the following concentrations:
BOD: 150 mg/l.
SS: 150 mg/l.
TEN: 30 mg/l.
4. If wastewater discharge is actually measured by means of a sewage meter or other device acceptable to the Township, then K = 1.0 and Q is the measured wastewater flow. If wastewater is not directly measured, then K shall be 0.95 and Q is the metered water consumption, except that the Township may agree with a particular industrial user that K will be some other percentage, based on reasonable estimation of waste discharged to other systems than the Township sewerage system.
