6. Beginning on February 16, 1998, a discharger shall not permit effluent that would ordinarily flow past a sampling point established under this Regulation to be discharged from the discharger’s plant without flowing past that sampling point, regardless of whether it would be convenient to do so because of a maintenance operation, a breakdown in equipment or any scheduled or unscheduled event.  O. Reg. 64/95, s. 6. Sampling and Analytical Procedures
7. (1) Each discharger shall carry out the establishment of sampling point obligations of this Regulation and the sampling and analysis obligations of this Regulation, including quality control sampling and analysis obligations, in accordance with the procedures 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.  O. Reg. 238/07, s. 1. (2) Each discharger shall maintain the sampling equipment used at the discharger’s plant for sampling required by this Regulation in a way that ensures that the samples collected at the plant under this Regulation accurately reflect the level of discharge of each limited parameter, merged parameter, assessment parameter and specific parameter from the plant.  O. Reg. 64/95, s. 7 (2). PART II   SAMPLING POINTS Establishment and Elimination of Sampling Points
8. (1) Each discharger shall, by May 15, 1995, establish a sampling point at each sampling point location designated as a process effluent sampling point in the Table for the discharger’s plant in Schedule 2. O. Reg. 311/17, s. 2 (1). (2) Each discharger shall, by May 15, 1995, establish a sampling point at each sampling point location designated as a process effluent batch sampling point in the Table for the discharger’s plant in Schedule 4. O. Reg. 311/17, s. 2 (2). (3) Each discharger shall, by May 15, 1995, establish a sampling point at each sampling point location designated as a merged effluent sampling point in the Table for the discharger’s plant in Schedule 5. O. Reg. 311/17, s. 2 (3). (4) Each discharger shall, by May 15, 1995, establish a sampling point at each sampling point location designated as a cooling water effluent sampling point in the Table for the discharger’s plant in Schedule 6. O. Reg. 311/17, s. 2 (4). (5) If the Director is satisfied, on the basis of written submissions from a discharger, that one or more of the circumstances described in subsection (6) exist at the discharger’s plant, with the result that it is impractical to maintain or use a sampling point established at the plant under this Regulation, the Director may give the discharger written permission to eliminate the sampling point. (6) For the purposes of subsection (5), the circumstances at the discharger’s plant that might make it impractical to maintain or use a sampling point are the following: 1. A process change or redirection of or change in the character of an effluent stream has occurred or is expected to occur at the discharger’s plant. 2. Equipment used for sampling or flow measurement at the sampling point is damaged or non-functional. 3. The effluent flowing in the stream on which the sampling point was established under this Regulation has been or is expected to be permanently eliminated. (7) Where a discharger is permitted to eliminate a sampling point because of a circumstance described in paragraph 1 or 2 of subsection (6), the discharger shall, within 90 days after the day on which the sampling point is eliminated, establish a replacement sampling point. (8) The replacement sampling point shall be established on the effluent stream from which the sampling point was eliminated, at a location approved in writing by the Director. (9) The Director shall not approve a location for the replacement sampling point unless he or she is satisfied that monitoring at the new location would yield results that would reflect the level of discharge of each limited parameter, merged parameter and assessment parameter from the discharger’s plant as reliably as did monitoring at the eliminated sampling point. (10) A discharger who replaces a sampling point under subsection (7) has all the same obligations in connection with the replacement sampling point that the discharger had in connection with the eliminated sampling point.
