(matières totales en suspension) [Repealed, SOR/95-426, s. 1] Subject to subsection (2), these Regulations apply to every new plant and every expanded plant. Where a plant becomes an expanded plant, these Regulations apply to the expanded plant on the first day of the month following the month in which the plant becomes an expanded plant. For the purpose of the definition deleterious substance in subsection 34(1) of the Act, the following substances resulting from the operations of a plant to which these Regulations apply are hereby prescribed as deleterious substances: biochemical oxygen demanding matter; and total suspended matter. Subject to these Regulations, the owner of a plant of a class set out in Column I of Schedule I may deposit a deleterious substance prescribed by section 4 if the actual daily deposit of each deleterious substance, determined in accordance with subsection 11(1), does not exceed the authorized daily deposit of that substance for that class of plant as set out in Column III of that Schedule; the average daily deposit of each deleterious substance during a month, determined in accordance with subsection 11(2), does not exceed the authorized average daily deposit of that substance for that class of plant as set out in Column IV of that Schedule; and the pH of each composite sample of effluent, determined in accordance with subsection 9(3), is between 6.0 and 9.0. The owner of a plant shall, for each type of effluent deposited by the plant, install and maintain facilities, including sampling connections and flow measuring devices, of such type as the Minister may in writing approve for sampling and analysing effluents for the purpose of enabling the Minister to determine whether the owner is complying with the limits of authorized deposits prescribed by section 5; take a composite sample on the regular basis prescribed by section 8; analyse the sample referred to in paragraph (b) in accordance with section 9; measure the flow in accordance with section 10; and determine the actual and average daily deposits of each deleterious substance in accordance with section 11. A composite sample shall be obtained by collecting effluent discharged from a plant during a processing day continually during a sampling period of 24 hours at a rate in proportion to the flow rate of the effluent discharged; or in such a manner that equal volumes of effluent are delivered into a receptacle at equal intervals not longer than one hour during a sampling period of 24 hours. The sampling referred to in paragraph 6(b) shall be made in the case of a plant where the weekly quantity of raw potatoes processed is less than 400 tonnes, on one processing day each week; and in the case of a plant where the weekly quantity of raw potatoes processed is 400 tonnes or more, on two processing days each week. For the purposes of paragraph 6(c), the concentration in milligrams per litre of a substance described in an item of Schedule II, in each composite sample, shall be determined using the test method set out in Column I and modified in Column II of that item; or any other method, approved in writing by the Minister, the results of which can be confirmed by the method referred to in paragraph (a). For the purposes of paragraph 6(c), procedures pertaining to sampling, preservation and storage of samples and prevention of interference relating to the test methods referred to in paragraph (1)(a), as outlined in the general sections of the publication Standard Methods for the Examination of Water and Waste Water, 14th edition (1975), published jointly by the American Public Health Association, American Water Works Association and the Water Pollution Control Federation, shall be adhered to. For the purposes of paragraph 6(c), the pH of a composite sample shall be determined using the test method prescribed by section 424 of the publication referred to in subsection (2); or For the purpose of paragraph 6(d), the flow of each type of effluent deposited by a plant shall be measured continuously and recorded. For the purposes of paragraph 6(e), the actual daily deposit per unit of production of each deleterious substance prescribed by section 4 shall be determined using the data obtained under subsection 9(1) and section 10 and shall be expressed in terms of kilograms per tonne of raw potatoes processed per day. For the purposes of paragraph 6(e), the average daily deposit per unit of production during a month of each deleterious substance prescribed by section 4 shall be determined by calculating the average of the results obtained under subsection (1) and shall be expressed in the terms set out in that subsection. The owner of a plant shall, within 30 days after the end of each month, sign, date and forward to the Minister a report, in such form as the Minister may in writing approve, showing for that month the actual daily deposit of deleterious substances deposited by the plant on each day that samples were taken, determined and expressed in accordance with subsection 11(1); the average daily deposit of deleterious substances deposited by the plant, determined and expressed in accordance with subsection 11(2); the pH of composite samples, determined in accordance with subsection 9(3); the daily production of the plant for each day that samples were taken expressed in terms of tonnes of raw potatoes processed; the weekly production of the plant for each week during the month, expressed in terms of tonnes of raw potatoes processed; the number of operating days; and the total daily flow, in litres, of each type of effluent discharged on each day that samples were taken. The owner of a new plant shall, before he deposits any deleterious substance prescribed by section 4, and the owner of an expanded plant shall, within 30 days of becoming subject to these Regulations, sign, date and forward to the Minister a declaration, in such form as the Minister may in writing approve, showing the projected weekly production of the plant expressed in terms of tonnes of raw potatoes processed; showing the projected annual production of the plant expressed in terms of tonnes of raw potatoes processed; and listing the major products produced. The owner of a plant shall, within 30 days after the end of each calendar year, sign, date and forward to the Minister a declaration, in such form as the Minister may in writing approve, showing the actual production of the plant for the previous year in terms of tonnes of raw potatoes processed. Where the owner of a plant establishes to the satisfaction of the Minister that for scientific and technical reasons a scheme of sampling and analysis, measurement or reporting referred to in sections 7, 9, 10 and 12 other than at the regular time interval frequencies required by section 8 is sufficient to enable the Minister to determine whether the owner is complying with the limits of authorized deposits prescribed by section 5, the Minister may, in writing, permit the owner to take and analyse samples of each effluent in accordance with the scheme on a regular basis specified in the letter of permission, measure the volume of each effluent in accordance with the scheme on a regular basis specified in the letter of permission, or report to the Minister in accordance with the scheme on a regular basis specified in the letter of permission and sections 7, 8, 9, 10 and 12 do not apply to the owner if he complies with the scheme on the regular basis specified in the letter of permission. NOTE: Other Potato Products Plants include plants that produce canned potato products, dehydrated potato products, frozen potato products and potato starch.
