70. The operator must measure the following at the sampling stations referred to in section 46:

(1)  TSS:

(a)  on each production day if an effluent is discharged into the environment, into a storm sewer or into a sewer system if, in the latter case, an effluent is also discharged into the environment or into a storm sewer;

(b)  3 times a week, on non-consecutive production days, if effluents are discharged into a sewer system;

(c)  on each day or 3 times a week, as the case may be, for the first 10 days following a total production stoppage and throughout the duration of equipment maintenance work performed during the total production stoppage if such work continues for more than 10 days; and

(d)  once a week for the remainder of the stoppage if wastewater from a storage area, leachate, municipal or industrial wastewater or septic tank sludge is discharged into the process water collection or treatment system or if cooking liquor or chemicals are stored in tanks of more than 1,000 litres;

(1.1)  BOD5:

(a)  3 times a week, on non-consecutive production days;

(b)  3 times a week for the first 10 days following a total production stoppage and throughout the duration of equipment maintenance work performed during the total production stoppage if such work continues for more than 10 days; and

(c)  once a week for the remainder of the stoppage if wastewater from a storage area, leachate, municipal or industrial wastewater or septic tank sludge is discharged into the process water collection or treatment system or if cooking liquor or chemicals are stored in tanks of more than 1,000 litres;

(2)  toxicity: once a month at an interval of at least 21 days, except in the case of an effluent discharged into a sewer system;

(3)  chemical oxygen demand, copper, lead, zinc, nickel and aluminum: once a month at an interval of at least 21 days;

(4)  (subparagraph revoked);

(5)  AOX

(a)  once a week on a day on which bleached pulp is produced, where a chlorinated product is used as a pulp bleaching agent, for an effluent discharged into the environment, into a storm sewer or into a sewer system if, in the latter case, an effluent is also discharged into the environment or into a storm sewer;

(b)  once a month, at an interval of at least 21 days, for an effluent discharged into a sewer system;

(6)  except if an effluent is discharged into a sewer system, chlorinated dioxins and furans: once every quarter, in January, April, July and October, on a day on which bleached pulp is produced if a chlorinated product is used as a bleaching agent, if section 47 does not apply; the congeners of dioxins and furans to be analyzed are those listed in Schedule II; and

(7)  (subparagraph revoked).

In the case of a total production stoppage, the requirements of subparagraphs 2 and 3 of the first paragraph no longer apply from the 60th day that follows the day on which the stoppage occurs if the standard provided for in subparagraph 2 of the first paragraph is complied with. The requirements continue to apply in the cases referred to in subparagraph d of subparagraph 1 and subparagraph c of subparagraph 1.1 of the first paragraph.

(2)  toxicity: once a month at an interval of at least 21 days, except in the case of an effluent discharged into a sewer system;

(3)  chemical oxygen demand, copper, lead, zinc, nickel and aluminum: once a month at an interval of at least 21 days;

(4)  petroleum hydrocarbons C10-C50: once a week for an effluent discharged into the environment or into a storm sewer and once a month, at an interval of at least 21 days, for an effluent discharged into a sewer system, except if they are already measured at the sampling stations referred to in section 47;

(5)  AOX

(a)  once a week on a day on which bleached pulp is produced, where a chlorinated product is used as a pulp bleaching agent, for an effluent discharged into the environment, into a storm sewer or into a sewer system if, in the latter case, an effluent is also discharged into the environment or into a storm sewer;

(b)  once a month, at an interval of at least 21 days, for an effluent discharged into a sewer system;

(6)  chlorinated dioxins and furans: once every quarter, in January, April, July and October, on a day on which bleached pulp is produced if a chlorinated product is used as a bleaching agent, if section 47 does not apply; the congeners of dioxins and furans to be analyzed are those listed in Schedule II; and

(7)  polychlorinated biphenyls: once every quarter, in January, April, July and October, if the quantity of recycled paper or paperboard exceeds 1,000 t per month, if section 47 does not apply; the homologous groups of polychlorinated biphenyls to be analyzed are those listed in Schedule III.

In the case of a total production stoppage, the requirements of subparagraphs 2, 3 and 4 of the first paragraph no longer apply from the 60th day that follows the day on which the stoppage occurs if the standards provided for in subparagraphs 2 and 4 of the first paragraph are complied with.
