Pulp and Paper Effluent Regulations

19 (1) The maximum BOD of the BOD matter and the maximum quantities of suspended solids that the owner or operator of a mill referred to in paragraph 15(1)(a) may be authorized to deposit, or to permit the deposit of, under an authorization are as follows:

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

  Q_d = (F × 2.5 × RPR) + [0.375 × (B_o or S_o)]

and

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

  Q_m = (F × D × 1.5 × RPR) + [0.225 × (B_o or S_o) × D]

  where

  B_o

  is the average daily BOD of the BOD matter in the waste water from sources other than a mill before it is treated by the mill, calculated for the preceding calendar year and expressed in kilograms,

  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,

  RPR

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

  S_o

  is the average daily quantity of suspended solids in the waste water from sources other than a mill before it is treated by the mill, calculated for the preceding calendar year and expressed in kilograms.

(2) The values of B_o and S_o and the supporting data referred to in paragraph 7(1)(h) for each calendar year shall be submitted to the authorization officer no later than January 31 of the following calendar year.

(3) If there are insufficient data on which to calculate the values of B_o and S_o, an estimate of those values may be made based on the data that are available.
