(matières en suspension de toute nature) When storm water is protected, in such manner as the Minister may approve in writing, from contamination by the deleterious substances prescribed in section 4 that originate from the refinery, the storm water shall be deemed not to be storm water for the purpose of these Regulations. When, prior to being deposited, liquid effluent or once-through cooling water has been treated, in such manner as the Minister may approve in writing, at a site outside a refinery for the purpose of removing therefrom the deleterious substances prescribed in section 4, the liquid effluent or once-through cooling water shall be deemed not to be liquid effluent or once-through cooling water for the purpose of these Regulations. These Regulations apply to every refinery that has not commenced the processing of crude oil prior to November 1, 1973 and that commences the processing of crude oil on or after that date. For the purpose of paragraph (c) of the definition deleterious substance in subsection 33(11) of the Act, the following substances are prescribed as deleterious substances; oil and grease; phenols; sulfide; ammonia nitrogen; total suspended matter; and any substance capable of altering the pH of liquid effluent or once-through cooling water. Subject to these Regulations, the owner of a refinery may deposit a deleterious substance prescribed in paragraph 4(a), (b), (c), (d) or (e) if the arithmetic mean of the actual deposits of each such substance during the month in which the deposit is made does not exceed the arithmetic mean of the authorized deposits of that substance in the same month for the refinery, as calculated in accordance with section 7; the actual deposit of each such substance deposited in each day by the refinery does not exceed, for more than one day in each month, the authorized deposit of that substance for the refinery, as calculated in accordance with subsection 8(1); and the actual deposit of each such substance deposited in each day by the refinery does not exceed the authorized deposit of that substance for the refinery as calculated in accordance with subsection 8(2). Subject to these Regulations, the owner of a refinery may deposit the deleterious substance prescribed in paragraph 4(f) if the pH of the liquid effluent or once-through cooling water is within the limits of 6.0 and 9.5. Subject to these Regulations, the owner of a refinery may deposit a deleterious substance prescribed in paragraph 4(a), (b) or (e), if the aggregate quantity of that substance contained in storm water being deposited in any month does not exceed the limit of the deposit authorized of that substance in the same month for the refinery, as calculated in accordance with subsection 9(2). When the owner of a refinery intends to deposit a deleterious substance prescribed in paragraph 4(a), (b), (c), (d) or (e), he shall, before making the deposit, sign, date and forward to the Minister a declaration, in such form as the Minister may prescribe, stating the reference crude rate of the refinery. For the purpose of subsection (1), the reference crude rate of a refinery is the maximum design stream day crude rate of the refinery, divided by 1,000. The owner of a refinery may revise the reference crude rate of the refinery at any time by signing, dating and forwarding to the Minister a declaration, in such form as the Minister may prescribe, stating the revised reference crude rate of the refinery. The owner of a refinery that deposits a deleterious substance prescribed in paragraph 4(a), (b), (c), (d) or (e) shall revise the reference crude rate of the refinery if the arithmetic mean of the stream day crude rates during any two consecutive months, divided by 1,000, excluding days when crude rates have been reduced due to refinery maintenance, is less than 85 per cent of the last declared reference crude rate of the refinery and shall sign, date and forward a declaration, in such form as the Minister may prescribe, stating the revised reference crude rate of the refinery. For the purpose of subsection (3), the revised reference crude rate of a refinery is the arithmetic mean of stream day crude rates sustained in commercial operation for at least seven consecutive days, divided by 1,000. For the purpose of subsection (4), the revised reference crude rate of a refinery is the arithmetic mean of stream day crude rates sustained in commercial operation for at least 14 consecutive days, divided by 1,000. The revised reference crude rate of a refinery takes effect on the first day of the month in which it is declared. For the purpose of paragraph 5(1)(a), the arithmetic mean of the authorized deposits for a refinery for a month shall be calculated using the amounts obtained in the calculations made under subsection (2). The authorized deposit for a refinery of a deleterious substance prescribed in paragraph 4(a), (b), (c), (d) or (e) shall, subject to section 9, be calculated for each day by multiplying the amount in Column II of an item of Schedule I for the deleterious substance set out in Column I of that item by the reference crude rate of the refinery for that month. For the purpose of paragraph 5(1)(b), the authorized deposit for a refinery of a deleterious substance prescribed in paragraph 4(a), (b), (c), (d) or (e) shall, subject to section 9, be calculated by multiplying the amount set out in Column III of an item of Schedule I for the deleterious substance set out in Column I of that item by the reference crude rate of the refinery for that month. For the purpose of paragraph 5(1)(c), the authorized deposit for a refinery of a deleterious substance prescribed in paragraph 4(a), (b), (c), (d) or (e) shall, subject to section 9, be calculated by multiplying the amount set out in Column IV of an item of Schedule I for the deleterious substance set out in Column I of that item by the reference crude rate of the refinery for that month. When storm water is deposited by a refinery in any day, the authorized deposit for the refinery of a deleterious substance prescribed in paragraph 4(a), (b) or (e), calculated in accordance with sections 7 and 8, may be increased for that day by the amount set out in Column II of an item of Schedule II for the deleterious substance set out in Column I of that item for each 10,000 Canadian gallons of storm water that is deposited. The limit of the deposit authorized in pounds per month of a deleterious substance prescribed in paragraph 4(a), (b) or (e) contained in storm water being deposited by a refinery in any month shall be calculated by multiplying the amount set out in Column III of an item of Schedule II for the deleterious substance set out in Column I of that item by the reference crude rate of the refinery for that month. For the purposes of subsection 5(1), when the owner of a refinery deposits a deleterious substance prescribed in paragraph 4(a), (b), (c), (d) or (e), he shall, within 30 days after the end of the month in which the deposit is made, determine for that month the actual deposit of each substance deposited by the refinery by making the measurements and calculations in accordance with Schedule IV. The owner of a refinery that deposits the deleterious substance prescribed in paragraph 4(f) shall, every day in the month during which the deposit is made or when requested by the Minister, monitor the deposit for the purpose of subsection 5(2) by performing the test referred to in Schedule III. The owner of a refinery that has deposited a deleterious substance prescribed in section 4 in any month shall sign, date and forward to the Minister within 30 days after the end of that month or when requested by the Minister, a report, in such form as the Minister may prescribe, indicating the arithmetic mean of the authorized deposits of that substance in that month for the refinery as calculated in accordance with section 7 and, where applicable, section 9; the authorized deposits of that substance in each day of that month for the refinery as calculated in accordance with sections 7 and 8 and, where applicable, section 9; the actual deposits of the deleterious substance prescribed in paragraph 4(a), (b), (c), (d) or (e) deposited in each day of that month by the refinery as calculated in accordance with Schedule IV; the arithmetic mean of the actual deposits of the deleterious substance prescribed in paragraph 4(a), (b), (c), (d) or (e) deposited in that month by the refinery as calculated in accordance with Schedule IV; the pH of composite samples measured in accordance with Schedule III; the reference crude rate of the refinery in that month; and such other information as may be requested by the Minister to enable him to determine whether the refinery is operating in compliance with the requirements of these Regulations. The owner of a refinery that deposits a deleterious substance prescribed in section 4 shall install and maintain facilities including sampling connections and flow-measuring devices that are acceptable to the Minister to enable the Minister to determine whether the refinery is operating in compliance with the requirements of these Regulations. The pH of composite samples obtained from each liquid effluent outfall and from the once-through cooling water shall be determined using the test method prescribed in section 221 of the publication Standard Methods for the Examination of Water and Waste Water, 13th edition (1971), published jointly by the American Public Health Association, American Water Works Association and the Water Pollution Control Federation; or another equivalent method, approved in writing by the Minister, the results of which can be confirmed by the method referred to in paragraph (a). For the purpose of section 1, composite sample has the same meaning as in subsection 2(2) of Schedule IV. The flow rates of all liquid effluents and once-through cooling water deposited by a refinery shall be measured and recorded continuously in Canadian gallons per minute. The concentration in milligrams per litre of a deleterious substance prescribed in paragraph 4(a), (b), (c), (d) or (e) in composite samples obtained from each liquid effluent outfall and from the once-through cooling water shall be determined every Monday, Wednesday and Friday, or as requested by the Minister, using the test method referred to in Column II of an item of the table to this Schedule and modified as set out in Column III of that item in respect of the deleterious substance set out in Column I of that item; or any other equivalent method, approved in writing by the Minister, the results of which can be confirmed by the method referred to in paragraph (a). For the purpose of subsection (1), a composite sample is the quantity of liquid effluent or once-through cooling water that is collected continually during a sampling period of 24 hours at a rate in proportion to the flow rate of the liquid effluent or once-through cooling water; the quantity of liquid effluent or once-through cooling water that is collected so that a minimum of 96 equal volumes of liquid are delivered into a receptacle at equal time intervals over a sampling period of 24 hours; or in the case where the use of continuous stream analyzers have been approved by the Minister, the liquid effluent or once-through cooling water itself. For the purpose of this section, procedures pertaining to sampling, the preservation and storage of samples and the prevention of interference, as outlined in the general sections relating to the specific test methods set out in Column II of the table to this Schedule, should be adhered to. The actual deposit by a refinery of a deleterious substance prescribed in paragraph 4(a), (b), (c), (d) or (e) shall be calculated by using the amounts obtained under sections 1 and 2 of this Schedule for each day that the concentration of that deleterious substance has been determined. The arithmetic mean of the actual deposits referred to in paragraph 5(1)(a) of the Regulations shall be calculated using the amounts obtained under section 3 of this Schedule. For the purpose of subsection 5(3) of the Regulations, the actual quantity of a deleterious substance prescribed in paragraph 4(a), (b) or (e) of the Regulations contained in storm water deposited each month shall be calculated using the weighted average concentration, based on the quantity of storm water discharged for those days during which the concentration of that deleterious substance has been determined, and the total quantity of storm water discharged in that month.
