8. (1) Each discharger shall, by November 24, 1994, establish a sampling point on each process effluent, cooling water effluent, and salt evaporator effluent stream at the discharger’s plant, as necessary so that the plant loadings calculated under sections 12, 13 and 14 for total suspended solids and the concentrations determined under sections 15, 16 and 17 of total suspended solids accurately reflect the level of discharge of total suspended solids from the plant. (2) Despite subsection (1), a discharger need not establish a sampling point on a by-pass. (3) If circumstances change so that a new sampling point is necessary at a discharger’s plant in order to permit the calculation of plant loadings under sections 12, 13 and 14 for total suspended solids and the determination of concentrations under sections 15, 16 and 17 of total suspended solids that accurately reflect the level of discharge of total suspended solids from the plant, the discharger shall, within 30 days of the change, establish the new sampling point. (4) A discharger may eliminate a sampling point established under subsection (1) or (3) if the sampling point is no longer necessary to permit the calculation of plant loadings under sections 12, 13 and 14 for total suspended solids and the determination of concentrations under sections 15, 16 and 17 of total suspended solids that accurately reflect the level of discharge of total suspended solids from the plant. (5) For the purposes of this section, a plant loading for total suspended solids or a concentration of total suspended solids that is based on analytical results that are significantly affected by dilution or masking due to the merging of streams upstream of a sampling point at a plant is not a loading or a concentration that accurately reflects the level of discharge of total suspended solids from the plant. (6) In determining what is necessary to meet a discharger’s obligations to establish sampling points under this section, the discharger shall consider both which streams should have sampling points and where on a stream a sampling point should be located.  O. Reg. 561/94, s. 8. Reports on Sampling Points

9. (1) By December 5, 1994, each discharger shall submit to the Director a list and plot plan showing the sampling points established under this Regulation at the discharger’s plant as of November 24, 1994. (2) Within 30 days after establishing a sampling point under this Regulation that is not shown on a list and plot plan submitted under this section, the discharger shall give the Director a written notice describing the location of the sampling point, together with a revised list and plot plan showing the sampling point. (3) Within 30 days after eliminating a sampling point under this Regulation that is shown on a list and plot plan submitted under this section, the discharger shall give the Director a written notice describing where the sampling point used to be, together with a revised list and plot plan without the sampling point.  O. Reg. 561/94, s. 9. Use of Sampling Points Established under this Part

10. Subject to section 24, each discharger shall use the sampling points established under this Part for all sampling required by this Regulation.  O. Reg. 561/94, s. 10. PART III   CALCULATION OF LOADINGS AND CONCENTRATIONS Calculations under this Part — General

11. (1) For the purposes of performing a calculation under sections 12 to 17, a discharger shall use the actual analytical result obtained by the laboratory.  O. Reg. 561/94, s. 11 (1). (2) Despite subsection (1), where the actual analytical result is less than one-tenth of the analytical method detection limit set out in the Ministry of the Environment publication entitled “Protocol for the Sampling and Analysis of Industrial/Municipal Wastewater”, as amended from time to time, the discharger shall use the value zero for the purpose of performing a calculation under sections 12 to 17.  O. Reg. 235/07, s. 2. (3) Each discharger shall ensure that each calculation of a process effluent loading required by section 12 and each calculation of a process effluent concentration required by section 15 is performed as soon as reasonably possible after the analytical results on which the calculation is based become available to the discharger.  O. Reg. 561/94, s. 11 (3). (4) Each discharger shall ensure that each calculation of a cooling water effluent loading required by section 13 is performed in time to comply with subsection 37 (4) and each calculation of a cooling water effluent concentration required by section 16 is performed in time to comply with subsection 37 (6).  O. Reg. 561/94, s. 11 (4). Calculation of Loadings — Process Effluent

12. (1) Each discharger shall calculate, in kilograms, a daily process effluent stream loading for total suspended solids in each process effluent monitoring stream of the discharger for each day on which a sample is collected under this Regulation from the stream for analysis for total suspended solids. (2) When calculating a daily stream loading under subsection (1), the discharger shall multiply, with the necessary adjustment of units to yield a result in kilograms, the analytical result obtained from the sample for total suspended solids by the daily volume of effluent, as determined under section 30, for the stream for the day. (3) Each discharger shall calculate, in kilograms, a daily process effluent plant loading for total suspended solids for each day for which the discharger is required to calculate a daily process effluent stream loading for total suspended solids under subsection (1). (4) For the purposes of subsection (3), a daily process effluent plant loading for total suspended solids for a day is the sum, in kilograms, of the daily process effluent stream loadings for total suspended solids calculated under subsection (1) for the day. (5) Where a discharger calculates only one daily process effluent stream loading for total suspended solids for a day under subsection (1), the daily process effluent plant loading for total suspended solids for the day for the purposes of subsection (3) is the single daily process effluent stream loading for total suspended solids for the day. (6) Each discharger shall calculate, in kilograms, a monthly average process effluent plant loading for total suspended solids for each month in which a sample is collected under this Regulation more than once from a process effluent monitoring stream at the discharger’s plant for analysis for total suspended solids. (7) For the purposes of subsection (6), a monthly average process effluent plant loading for total suspended solids for a month is the arithmetic mean of the daily process effluent plant loadings for total suspended solids calculated under subsection (3) for the month.
