(a) in respect of a daily period, the amount determined using the formula
Qd = 0.375 x A
and
(b) in respect of a month, the amount determined using the formula
Qm = 0.225 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 BOD of the BOD matter that may be deposited during a daily period, expressed in kilograms, and
- Qm
- is the maximum BOD of the BOD matter that may be deposited during a month, expressed in kilograms.
(2) The maximum quantities of suspended solids that the owner or operator of an off-site treatment facility referred to in paragraph 15(1)(c) may be authorized to deposit under an authorization are as follows:
(a) in respect of a daily period, the amount determined using the formula
Qd = 0.563 x A
and
(b) in respect of a month, the amount determined using the formula
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
- Qm
- is the maximum quantity of suspended solids that may be deposited during a month, expressed in kilograms.
(3) The value of A and the supporting data referred to in paragraph 7(1)(i) for each calendar year shall be submitted to the authorization officer no later than January 31 of the following calendar year.
(4) If there are insufficient data on which to calculate the value of A, an estimate of that value may be made based on the data that are available.
