  • (a) in respect of a daily period, the amounts determined using the formula

    Qd = (F1 × 2.5 × RPR1) + (F2 × 2.5 × RPR2)

and

  • (b) in respect of a month, the amounts determined using the formula

    Qm = (F1 × D × 1.5 × RPR1) + (F2 × D × 1.5 × RPR2)

    where

    D
    is the number of calendar days in the month,
    F1
    is equal to a factor of 5 for BOD and 7.5 for suspended solids, expressed in kilograms per tonne of finished product other than dissolving grade sulphite pulp,

    is equal to a factor of 18 for BOD and 25 for suspended solids, expressed in kilograms per tonne of dissolving grade sulphite pulp,
    Qd
    is the maximum BOD of the BOD matter that may be deposited during a daily period or the maximum quantity of suspended solids that may be deposited during a daily period, as the case may be, expressed in kilograms,
    Qm
    is the maximum BOD of the BOD matter that may be deposited during a month or the maximum quantity of suspended solids that may be deposited during a month, as the case may be, expressed in kilograms,
    RPR1
    is the reference production rate of the mill for all finished product other than dissolving grade sulphite pulp, expressed in tonnes per day, and
    RPR2
