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. 560/94, 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. 234/07, 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. 560/94, 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 38 (4) and each calculation of a cooling water effluent concentration required by section 16 is performed in time to comply with subsection 38 (7).

12. (1) Each discharger shall calculate, in kilograms, a daily process effluent stream loading for each limited parameter 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 the parameter. (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 the parameter by the daily volume of effluent, as determined under section 31, for the stream for the day. (3) Each discharger shall calculate, in kilograms, a daily process effluent plant loading for each limited parameter for each day for which the discharger is required to calculate a daily process effluent stream loading for the parameter under subsection (1). (4) For the purposes of subsection (3), a daily process effluent plant loading for a parameter for a day is the sum, in kilograms, of the daily process effluent stream loadings for the parameter calculated under subsection (1) for the day. (5) Where a discharger calculates only one daily process effluent stream loading for a parameter for a day under subsection (1), the daily process effluent plant loading for the parameter for the day for the purposes of subsection (3) is the single daily process effluent stream loading for the parameter for the day. (6) Each discharger shall calculate, in kilograms, a monthly average process effluent plant loading for each limited parameter 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 the parameter. (7) For the purposes of subsection (6), a monthly average process effluent plant loading for a parameter for a month is the arithmetic mean of the daily process effluent plant loadings for the parameter calculated under subsection (3) for the month.

13. (1) Each discharger shall calculate, in kilograms, a daily cooling water effluent stream loading for each Schedule 2 assessment parameter in each cooling water effluent monitoring stream of the discharger for each day on which a sample is collected under this Regulation from the stream for analysis for the parameter. (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 the parameter by the daily volume of effluent, as determined under section 31, for the stream for the day. (3) Each discharger shall calculate, in kilograms, a daily cooling water effluent plant loading for each Schedule 2 assessment parameter for each day for which the discharger is required to calculate a daily cooling water effluent stream loading for the parameter under subsection (1). (4) For the purposes of subsection (3), a daily cooling water effluent plant loading for a parameter for a day is the sum, in kilograms, of the daily cooling water effluent stream loadings for the parameter calculated under subsection (1) for the day. (5) Where a discharger calculates only one daily cooling water effluent stream loading for a parameter for a day under subsection (1), the daily cooling water effluent plant loading for the parameter for the day for the purposes of subsection (3) is the single daily cooling water effluent stream loading for the parameter for the day. (6) Each discharger shall calculate, in kilograms, a monthly average cooling water effluent plant loading for each Schedule 2 assessment parameter for each month in which a sample is collected under this Regulation more than once from a cooling water effluent monitoring stream at the discharger’s plant for analysis for the parameter. (7) For the purposes of subsection (6), a monthly average cooling water effluent plant loading for a parameter for a month is the arithmetic mean of the daily cooling water effluent plant loadings for the parameter calculated under subsection (3) for the month.  O. Reg. 560/94, s. 13. Calculation of Loadings — Overflow Effluent

14. (1) Each discharger shall calculate, in kilograms, an overflow effluent stream loading for each Schedule 3 assessment parameter in each overflow effluent monitoring stream of the discharger for each eight-hour period during which a sample is collected under this Regulation from the stream for analysis for the parameter. (2) When calculating a 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 the parameter by the volume of effluent, as determined under section 31, for the stream for the eight-hour period. (3) Each discharger shall calculate, in kilograms, a daily overflow effluent stream loading for each Schedule 3 assessment parameter in each overflow effluent monitoring stream of the discharger for each day for which the discharger is required to calculate an overflow effluent stream loading for the parameter under subsection (1). (4) For the purposes of subsection (3), a daily overflow effluent stream loading for a parameter for a day is the sum, in kilograms, of all the eight-hour period overflow effluent stream loadings for the parameter calculated under subsection (1) for the day. (5) Where a discharger calculates only one overflow effluent stream loading for a parameter under subsection (1) for a stream for a day, the daily overflow effluent stream loading for the parameter for the day for the purposes of subsection (3) is the single overflow effluent stream loading calculated for the parameter under subsection (1).
