PART 2Conditions Governing Authority to Deposit (continued)

DIVISION 2Effluent Monitoring Conditions (continued)

Reduced Frequency of Acute Lethality Testing (continued)

 [Repealed, SOR/2018-99, s. 15]

Obligation to Record All Test Results

 The owner or operator of a mine shall record without delay the data referred to in section 9.1 of Reference Method EPS 1/RM/10, section 8.1 of Reference Method EPS 1/RM/13, section 8.1 of Reference Method EPS 1/RM/14 and section 9.1 of Reference Method STB 1/RM/60 for each acute lethality test.

Volume of Effluent

  •  (1) The owner or operator of a mine shall record, in cubic metres, the total monthly volume of effluent deposited from each final discharge point for each month during which there was a deposit.

  • (2) The total monthly volume of effluent deposited shall be either

    • (a) determined on the basis of the average of the flow rates, expressed in cubic metres per day, measured and calculated as follows:

      • (i) by measuring the flow rate at the same time as samples are collected under section 12,

      • (ii) by calculating the average monthly flow rate by adding the flow rate measurements taken during the month and dividing the total by the number of times the flow rate was measured, and

      • (iii) by multiplying the average monthly flow rate by the number of days during the month that effluent was deposited; or

    • (b) determined by using a monitoring system that provides a continuous measure of the volume of effluent deposited.

  • (3) The owner or operator shall

    • (a) measure the flow rate or volume of effluent deposited by using a monitoring system that is accurate to within 15% of measured flow rate or volume; and

    • (b) maintain and calibrate the monitoring system at least once in each year and record the results, as well as the date on which and the manner in which the requirement to maintain and calibrate has been met.

  • SOR/2012-22, s. 5
  • SOR/2018-99, s. 17

Calculation of Monthly Mean Concentration and Loading

  •  (1) With respect to the deleterious substances that are contained in the effluent deposited from each final discharge point, the owner or operator of a mine shall, for each month during which there is a deposit and during which samples are collected, record the monthly mean concentration

    • (a) in mg/L for deleterious substances referred to in paragraphs 3(a) to (g) and (i); and

    • (b) in Bq/L for a deleterious substance referred to in paragraph 3(h).

  • (2) If the analytical result from any test conducted under section 12 or 13 is less than the method detection limit used for that test, the test result shall be considered to be equal to one half of the detection limit used for the purpose of calculating the monthly mean concentration.

  • SOR/2006-239, s. 9
  • SOR/2018-99, s. 18
  •  (1) With respect to the deleterious substances that are contained in the effluent deposited from each final discharge point, the owner or operator of a mine shall, for each month and for each calendar quarter during which there was a deposit and during which a sample is collected, record the loading

    • (a) in kg for deleterious substances referred to paragraphs 3(a) to (g) and (i); and

    • (b) in MBq for a deleterious substance referred to in paragraph 3(h).

  • (2) The owner or operator shall determine the loading for each month using the following formula:

    ML = C × V / 1,000

    where

    ML
    is the loading for a month;
    C
    is the monthly mean concentration of the deleterious substance, recorded under section 19.1; and
    V
    is the total monthly volume of effluent deposited from each final discharge point, recorded under section 19.
  • (3) The owner or operator shall determine the loading for each calendar quarter using the following formula:

    QL = C × V / 1,000

    where

    QL
    is the loading for a calendar quarter;
    C
    is the mean of the monthly mean concentrations of the deleterious substance for that calendar quarter, recorded under section 19.1; and
    V
    is the total volume of effluent deposited from each final discharge point during that calendar quarter, based on the sum of the total monthly volumes of effluent deposited from each final discharge point, recorded under section 19.
