SOR-2012-139 Wastewater Systems Effluent Regulations

These Regulations apply in respect of a wastewater system that, when it deposits effluent via one or more final discharge points, deposits a deleterious substance prescribed in section 5 in any water or place referred to in subsection 36(3) of the Act and that

Despite paragraph (1)(a), these Regulations do not, for the subsequent calendar year, apply in respect of a wastewater system referred to in that paragraph that, during a calendar year, collected an average daily volume of less than 100 m 3 of influent.

These Regulations do not apply in respect of a wastewater system located

These Regulations do not apply in respect of a wastewater system that is located on the site of an industrial, commercial or institutional facility if the wastewater system is designed to collect influent whose volume consists of less than 50% blackwater and greywater combined.

These Regulations do not apply in respect of a mill as defined in section 2 of the Pulp and Paper Effluent Regulations.

If an owner of at least two original wastewater systems — none of which treats its wastewater in a manner that would permit the deposit of effluent, via its final discharge points, that meets the condition set out in paragraph 6(1)(a) or (b) — plans to consolidate those original wastewater systems into a future consolidated wastewater system, the original wastewater systems that will be consolidated constitute a fictional consolidated wastewater system during the period beginning on the day on which a consolidation plan that meets the requirements of subsection (3) is received by an authorization officer and ending on the day on which the future consolidated wastewater system is put into service.

The final discharge point of the fictional consolidated wastewater system is considered to be the final discharge point of the original wastewater systems that is allocated the greatest number of points under the table to Schedule 2.

The consolidation plan must contain a description of the modifications to be made to each of the original wastewater systems, including a description of the modifications to be made to their processes, so that the effluent deposited via the final discharge point of the future consolidated wastewater system will not be acutely lethal and will meet the conditions for authorization set out in subsection 6(1), along with a schedule for implementation of the plan.

For the purpose of paragraph 36(4)(b) of the Act, the owner or operator of a wastewater system may — during a given calendar year, quarter or month, as determined in accordance with subsection (2) — deposit or permit the deposit of effluent that contains any of the deleterious substances prescribed in section 5 of these Regulations via each of the system’s final discharge points in any water or place referred to in subsection 36(3) of the Act if the effluent is not acutely lethal as determined in accordance with section 15, the maximum concentration of un-ionized ammonia in the effluent is less than 1.25 mg/L, expressed as nitrogen (N), at 15˚C ± 1˚C, and — during the previous calendar year, previous quarter or previous month, as the case may be — the effluent met the following conditions:

The maximum concentration and the averages referred to in subsection (1) must be determined on the following basis:

The averages referred to in paragraphs (1)(a) and (b) must be determined

The determination of averages made in accordance with subsection (3) must take into account the results of the determination, by a laboratory referred to in section 16, of the elements referred to in subsection 10(6) for any sample in excess of the number of samples required by subsections 10(1) to (4).

For an intermittent wastewater system or a continuous wastewater system with a hydraulic retention time of five or more days, the determination of the average referred to in paragraph (1)(b) is not to take into account the result of any determination of the concentration of suspended solids in a sample of effluent referred to in paragraph 10(6)(b) that was taken during any four months during the period beginning on May 1 and ending on November 30, if that result is greater than 25 mg/L and is caused by a bloom of algae or proliferation of aquatic invertebrates.

If subsection (5) applies to every sample referred to in paragraph (3)(a) or (b) that is used to determine the average referred to in paragraph (1)(b), that average is deemed to be 0 mg/L.

The authorization granted to an owner or operator under subsection (1) is conditional on the owner or operator

The owner or operator of a wastewater system must, for each calendar year, calculate the average daily volume of effluent deposited via all of the system’s final discharge points by

The volume of effluent during each day referred to in paragraph (1)(a) must be determined

For the purpose of paragraph (1)(a), if the owner or operator estimates the daily volume of effluent deposited via the final discharge point based on the measured rate of flow referred to in clause (2)(a)(i)(B) or (b)(i)(B), the estimation is to be done as follows:

The owner or operator of a wastewater system who has established a method of estimation of the volume of effluent must ensure that it is based on generally accepted engineering practices and use it to estimate the daily volume of effluent deposited via the final discharge point with a margin of error of ±15%.

If the average daily volume of effluent deposited via the final discharge point of a wastewater system for a previous calendar year cannot be determined under paragraph 7(2)(a) or (b), as the case may be, that average daily volume must be determined on the basis of the system’s average design rate of flow of influent.

If subsection (1) has been applied in respect of a wastewater system for a calendar year, it is not to be applied in respect of the wastewater system for any subsequent calendar year.

The owner or operator of a wastewater system must install monitoring equipment that provides a continuous measure of the daily volume or of the rate of flow of the influent or effluent.

The owner or operator must maintain the monitoring equipment so that it may be used to determine the volume of effluent deposited via the final discharge point.

The owner or operator must calibrate the monitoring equipment in accordance with the recommendations of the manufacturer or licensed professional or, in the absence of such recommendations, must calibrate the equipment at least once in every calendar year and at least five months after the most recent calibration.

The monitoring equipment must determine the volume or rate of flow with a margin of error of ±15%.

The owner or operator of an intermittent wastewater system must, during each period referred to in paragraph 3(a), take at each of the system’s final discharge points a grab or composite sample of effluent at the following minimum frequencies:

Despite subsection (1), if a grab or composite sample of effluent has been collected at a sampling location referred to in subsection (5) within two weeks of the period referred to in paragraph 3(a) for the government of the province where the wastewater system is located or under an Act of Parliament, and if the determinations referred to in subsection (6) and, if applicable, paragraph 38(b) were made, the owner or operator of a system is not required to take a sample during the first 30 days of deposit and may use the results of the determinations made on the sample of effluent collected prior to deposit.

The owner or operator of a continuous wastewater system must take at each of the system’s final discharge points, during each calendar year, a sample of effluent of the type set out in column 2 of the table to this subsection that corresponds to the average daily volume of effluent set out in column 1 that is deposited via all final discharge points during the previous calendar year and must do so at the frequency set out in column 3. TABLE Item Column 1 Column 2 Column 3 Average Daily Volume, Deposited (m 3) Type of Sample To Be Taken Minimum Sampling Frequency 1≤ 2 500 Grab or composite Monthly, with each sample taken at least 10 days after any previous sample 2> 2 500 and ≤ 17 500 Composite Every two weeks, but at least seven days after any previous sample 3> 17 500 and ≤ 50 000 Composite Weekly, with each sample taken at least five days after any previous sample 4> 50 000 Composite Three days per week, with each sample taken at least one day after any previous sample

Despite subsections (1) and (4), the owner or operator of an intermittent wastewater system, or of a continuous wastewater system with a hydraulic retention time of five or more days, may take a grab or composite sample of effluent at a sampling location other than the final discharge point if the sampling location yields a representative sample as if the sample had been collected at the final discharge point and if the sampling location and sampling procedure are determined by a licensed professional.

The owner or operator must, for each sample referred to in subsection (1) to (4), determine or cause the determination of the following elements:

The owner or operator of an intermittent wastewater system must take at each of the system’s final discharge points, for each period referred to in paragraph 3(a) during each calendar year, a grab sample of effluent on the day a deposit begins if the average daily volume of effluent deposited via all of the final discharge points during the previous calendar year was more than 2 500 m 3.

The owner or operator of a continuous wastewater system must take at each of the system’s final discharge points, during each calendar year, a grab sample of effluent at the minimum sampling frequency set out in column 2 of the table to this subsection that corresponds to the average daily volume of effluent set out in column 1 deposited via all of the system’s final discharge points during the previous calendar year. TABLE Item Column 1 Column 2 Average Daily Volume Deposited (m 3) Minimum Sampling Frequency 1> 2 500 and ≤ 50 000 Quarterly, with each sample taken at least 60 days after any previous sample 2> 50 000 Monthly, with each sample taken at least 21 days after any previous sample

For each sample taken under subsection (1) or (2), the owner or operator must determine or cause the determination of whether it is acutely lethal in accordance with section 15.

If a sample is determined to be acutely lethal, the owner or operator must take a grab sample without delay, and then subsequently once every two weeks, but at least seven days after the previous sample, and determine or cause the determination of whether it is acutely lethal in accordance with section 15.

If three consecutive samples taken in accordance with subsection (4) are determined not to be acutely lethal, subsections (1) to (3) apply to subsequent samples.

For greater certainty, subsection (4) applies to any subsequent sample referred to in subsection (5) that is determined to be acutely lethal when tested under subsection (3).

The minimum sampling frequency set out in column 2 of the table to subsection (2) is reduced

The concentration of un-ionized ammonia in the effluent must be determined in accordance with the following formula: total ammonia × 1 1 +10 9.56 – pH where total ammonia is the concentration of total ammonia determined in accordance with subsection (2), expressed in mg/L as nitrogen (N); and pH is the pH of the effluent adjusted to 15°C ± 1°C and determined in accordance with subsection (3).

The concentration of total ammonia in the effluent must be determined by using an aliquot of the same sample of effluent from which the pH of the effluent was determined and testing it in accordance with a total ammonia test.
