14 Unless an authorization has been issued authorizing the deposit of BOD matter or suspended solids, as the case may be, the maximum BOD of the BOD matter that may be deposited from a mill and the maximum quantities of suspended solids that may be deposited from a mill are as follows:

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

  Q_d = F × 2.5 × RPR

and

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

  Q_m = F × D × 1.5 × RPR

  where

  D

  is the number of calendar days in the month,

  F

  is equal to a factor of 5 for BOD and 7.5 for suspended solids, expressed in kilograms per tonne of finished product,

  Q_d

  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, expressed in kilograms,

  Q_m

  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, expressed in kilograms, and

  RPR

  is the reference production rate of the mill for all finished product, expressed in tonnes per day.
