(a) Process waste water shall not be discharged to a POTW at a flow rate or pollutant mass loading rate which is excessive over any time period during the peak load at a POTW. Excessive discharges are defined as those in which the flow of BOD 5 or total suspended solids (TSS) exceed the respective values of P from the following formula:
P = K(Q+R)−S
where:
P = maximum allowable peak waste load for the new corn wet milling source to be discharged to the POTW (gallons per one hour for flow and pounds per day for BOD 5 and TSS).
Q = average existing waste load to POTW.
R = average waste load for the new corn wet milling source to be discharged to POTW.
S = existing peak load of POTW.
K = 2. When the ratio of (S/Q) is greater than 1.5, K = 3.
Calculations are to be based on dry weather conditions.
