(3)  the pH value must be between 6.0 and 9.5.

Compliance of the concentrations provided for in subparagraphs 1 and 2 of the first paragraph is assessed periodically on the basis of an average effluent discharge calculated for the periods listed in Schedule I.

The operator of a treatment plant must collect samples or take measurements of the effluent from its plant at the frequencies provided for in Schedule I and the operator must analyze them according to the procedure established in the Schedule.

O.C. 1305-2013, s. 6.

7. The effluent from a treatment plant may not show acute toxicity for rainbow trout Oncorhynchus mykiss or daphnia Daphnia magna, or both. Acute toxicity corresponds to a mortality rate of more than 50% of the organisms exposed to the undiluted effluent.

ASSESSMENT OF COMPLIANCE WITH DISCHARGE STANDARDS OF THE EFFLUENT FROM A TREATMENT PLANT

(1) Compliance with the standards relating to CBOD5 and SS provided for in subparagraphs 1 and 2 of the first paragraph of section 6 is assessed by collecting samples of the effluent from a treatment plant at the frequencies appearing in Table 1, according to the class of treatment plant concerned.

(2) All the samples collected must be analyzed by laboratories accredited under section 118.6 of the Environment Quality Act (chapter Q-2).

(3) The results of the analyses of samples collected are compiled in a manner to establish an average of those results for the periods appearing in Table 1, according to the class of treatment plant concerned.

(4) The laboratory produces a certificate of analysis which is sent to the operator of the treatment plant concerned.

(5) Compliance with the standards relating to pH provided for in subparagraph 3 of the first paragraph of section 6 is assessed by taking one-time measurements of the effluent from a treatment plant at the frequencies appearing in Table 1, according to the class of treatment plant concerned.

(6) The pH measurements are taken using a measuring device able to assess the pH with a precision to the tenth of a unit.

(7) The samples collected and the measurements taken during the period of periodic emptying of a treatment plant of the non-aerated lagoon type, regardless of the class of treatment plant to which it belongs, must be done after the first third and after the second third of each of the emptying periods.

(8) The frequencies and the calculation periods of the averages provided for in Table 1 do not apply if the operator of a treatment plant is the holder of a depollution attestation issued under section 31.33 of the Environment Quality Act and that attestation provides different frequencies and periods of calculation to ensure stricter periodic monitoring than that provided for in Table 1.

TOXICITY TEST OF THE EFFLUENT FROM A TREATMENT PLANT

(1) The effluent from a treatment plant must undergo an acute toxicity test performed on rainbow trout (Oncorhynchus mykiss) and another performed on daphnia Daphnia magna in accordance with the most recent version of one of the following methods:

(1) for rainbow trout (Oncorhynchus mykiss): biological test method EPS1/RM/13 “Biological Test Method: Reference Method for Determining Acute Lethality of Effluents to Rainbow Trout”, published by Environment Canada, carried out according to the single-concentration or multi-concentration procedure, as the case may be;

(2) for daphnia Daphnia magna: MA 500 – D.mag. 1.1 lethal toxicity method “Détermination de la toxicité létale CL50 48h Daphnia magna”, published by the Centre d’expertise en analyse environnementale du Québec of the Ministère du Développement durable, de l’Environnement, de la Faune et des Parcs.

(2) Acute toxicity tests are performed at the following frequencies, according to the class of treatment plant concerned, unless different frequencies are provided in the depollution attestation issued under section 31.33 of the Environment Quality Act (chapter Q-2) for the municipal wastewater treatment works concerned:

                                     - Daphnia magna

1. Quarterly tests must be at intervals of at least 2 months.

2. Monthly tests must be at intervals of at least 3 weeks.

(3) If a positive result is obtained for an acute toxicity test, the operator must, within 7 days, have a second test performed on the same species. If the result of the second test is negative, the operator must have a third test performed on the same species, within 7 days, to determine the final result of the test.

For rainbow trout (Oncorhynchus mykiss), the second and third tests must be performed according to the multi-concentration procedure of the method provided for in paragraph 1 of section 1.
