17 The owner or operator of a wastewater system must keep the report on each determination made by an accredited laboratory referred to in section 16 and a record that contains the following information:
(a) for any final discharge point,
(i) the date of each day on which effluent was not deposited via the final discharge point,
(ii) the date of each day on which effluent was deposited via the final discharge point, and
(iii) for each of the days referred to in subparagraph (ii)
(A) for a wastewater system whose daily volume of effluent referred to in paragraph 7(1)(a) was determined using monitoring equipment referred to in section 9
(I) the daily volume of the effluent, expressed in m3, if that volume is yielded by a continuous measure, and
(II) the estimated daily volume, expressed in m3, as determined in accordance with subsection 7(3) and the results of the measurement and the calculation referred to in paragraphs 7(3)(a) and (b), in any other case, and
(B) for a wastewater system whose daily volume of effluent referred to in paragraph 7(1)(a) was determined using a method of estimation in accordance with subsection 7(4), the estimated daily volume, expressed in m3 and the method of estimation that was used, and
(iv) the average daily volume of effluent deposited annually, expressed in m3, determined in accordance with subsection 8(1), if applicable;
(b) for each combined sewer overflow point via which effluent is deposited because of precipitation, including the melting of snow or ice, that resulted in excess wastewater in the wastewater system,
(i) the date of each day on which effluent was deposited via the overflow point,
(ii) for each of those days, the duration or estimated duration, expressed in hours, of the deposit, along with an indication of whether it is the duration or an estimated duration and
(A) the daily volume of the effluent deposited, expressed in m3, if that volume is yielded by a continuous measure, and
(B) the estimated daily volume of the effluent deposited, expressed in m3, in any other case,
(iii) the volume or estimated volume, expressed in m3, of effluent for each month during which effluent was deposited via the overflow point, and
(iv) the number of days in each of those months during which effluent was deposited via the overflow point;
(c) for any monitoring equipment referred to in section 9,
(i) a description, including its type,
(ii) if applicable, the manufacturer’s specifications, the year of manufacture and the model number,
(iii) each date on which the equipment was calibrated and its degree of accuracy after each calibration,
(iv) the date on which the equipment was installed and, if applicable, the date on which it ceased to be used for monitoring and on which it was replaced,
(v) the manufacturer’s recommendations for its operation, maintenance and calibration, with supporting documents if they are available, and
(vi) a document setting out the calibration procedure that is prepared, signed and certified by a licensed professional, if the monitoring equipment is calibrated in accordance with the recommendations of the licensed professional;
(d) for each sample referred to in subsection 10(1) to (4), as the case may be, and, if applicable, subsection 6(4),
(i) the results of the determinations referred to in subsection 10(6),
(ii) a statement as to whether the sample is a grab sample or a composite sample and the date on which the sample was taken,
(iii) a document setting out the sampling location and sampling procedure that is signed and certified by the licensed professional, if the sample is taken at a sampling location other than the final discharge point, and
(iv) a statement as to whether the result of the determination of the concentration of suspended solids was not taken into account in the average referred to in paragraph 6(1)(b), in accordance with subsection 6(5);
(e) for any dechlorination system referred to in paragraph 6(7)(h),
(i) a description of the system, including the manufacturer’s specifications, the year of manufacture and the model number, if any, and
(ii) any results of the determination of the concentration of total residual chlorine in the effluent and a description of how that determination was made;
(f) for each sample referred to in section 11 whose acute lethality was determined in accordance with section 15, the information referred to in section 8 of Reference Method EPS 1/RM/13 and, if the acute lethality of the effluent was determined in accordance with that method used with the Procedure for pH Stabilization EPS 1/RM/50, section 3 of that procedure;
(g) if the owner or operator holds of a temporary authorization issued under subsection 36(1),
(i) for each sample referred to in paragraph (d),
(A) the result of the determination referred to in paragraph 38(b),
(B) the results of the determination of the concentration of total ammonia in the effluent and of the pH of the effluent referred to in subsections 14(2) and (3), respectively, that were used to make the determination referred to in clause (A),
(C) a statement as to whether the sample is a grab sample or a composite sample and the date on which the sample was taken, and
(ii) the result of the determination referred to in paragraph 38(c) for each August and a description of how that determination was made.
