16. (1) Each discharger shall ensure that each daily process effluent plant loading calculated for a parameter under section 12 in connection with the discharger’s plant does not exceed the daily plant loading limit specified for the parameter and the plant in Column 3 of the Table for the plant in Schedule 2.  O. Reg. 63/95, s. 16 (1); O. Reg. 313/17, s. 3 (1). (2) Each discharger shall ensure that each monthly average process effluent plant loading calculated for a parameter under section 12 in connection with the discharger’s plant does not exceed the monthly average plant loading limit specified for the parameter and the plant in Column 4 of the Table for the plant in Schedule 2.  O. Reg. 63/95, s. 16 (2); O. Reg. 313/17, s. 3 (1). (3) Each discharger shall ensure that each process effluent batch stream loading calculated for a parameter under section 13 in connection with the discharger’s plant does not exceed the batch loading limit specified for the parameter and the plant in Column 3 of the Table for the plant in Schedule 4.  O. Reg. 63/95, s. 16 (3); O. Reg. 313/17, s. 3 (2). (4) Each discharger shall control the quality of each process effluent monitoring stream and each process effluent batch monitoring stream at the discharger’s plant to ensure that the concentration of 2,3,7,8-tetrachlorodibenzo-para-dioxin and the concentration of 2,3,7,8-tetrachlorodibenzofuran are both non-measurable in any sample collected at a process effluent sampling point or a process effluent batch sampling point at the plant.  O. Reg. 63/95, s. 16 (4). (5) For the purposes of subsection (4), the concentration of 2,3,7,8-tetrachlorodibenzo-para-dioxin in a sample is non-measurable if analysis of the sample shows a concentration of 2,3,7,8-tetrachlorodibenzo-para-dioxin of less than 20 picograms per litre and the concentration of 2,3,7,8-tetrachlorodibenzofuran in a sample is non-measurable if analysis of the sample shows a concentration of 2,3,7,8-tetrachlorodibenzofuran of less than 50 picograms per litre.  O. Reg. 63/95, s. 16 (5). (6) Each discharger shall control the quality of each process effluent monitoring stream and each process effluent batch monitoring stream at the discharger’s plant to ensure that the total toxic equivalent concentration of 2,3,7,8 substituted dioxin and furan congeners in any sample collected at a process effluent sampling point or a process effluent batch sampling point at the plant, calculated in accordance with the methods described in the Ministry of the Environment publication entitled “Protocol for the Sampling and Analysis of Industrial/Municipal Wastewater”, as amended from time to time, does not exceed 60 picograms per litre.  O. Reg. 237/07, s. 3. (7) Subject to subsection (8), each discharger shall control the quality of each process effluent monitoring stream and each process effluent batch monitoring stream at the discharger’s plant to ensure that the pH value of any sample collected at a process effluent sampling point or a process effluent batch sampling point at the plant is within the range of 6.0 to 9.5.  O. Reg. 63/95, s. 16 (7). (8) Throughout any day on which a discharger has used an alternate sampling point on a process effluent monitoring stream for sampling required by section 25, as permitted by subsections 25 (7) and (8), the discharger, (a)  shall control the quality of the stream to ensure that the pH value of any sample collected at the alternate sampling point on the stream is within the range of 6.0 to 9.5; and (b)  need not comply with subsection (7) with respect to the stream.  O. Reg. 63/95, s. 16 (8). Lethality Limits
