    Qm = 0.338 x A x D

    where

    A
    is the average daily BOD of the BOD matter in the effluent before it is treated by the off-site treatment facility, calculated for the preceding calendar year and expressed in kilograms,
    D
    is the number of calendar days in the month,
    Qd
    is the maximum quantity of suspended solids that may be deposited during a daily period, expressed in kilograms, and
