By-passes

5. Beginning on April 13, 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. 215/95, s. 5.

PART II
SAMPLING POINTS

Establishment and Elimination of Sampling Points

7. (1) Each discharger shall, by July 12, 1995, establish a sampling point on each non-event process effluent stream and event process effluent stream at the discharger’s plant, as necessary so that the concentrations determined under sections 11 and 12 and the plant loadings calculated under sections 13 and 14 for each limited parameter accurately reflect the level of discharge of each such parameter from the plant.

(2) If circumstances change so that a new sampling point is necessary at a discharger’s plant in order to permit the calculation of concentrations under sections 11 and 12 and the calculation of loadings under sections 13 and 14 for each limited parameter that accurately reflect the level of discharge of each such parameter from the plant, the discharger shall, within 30 days of the change, establish the new sampling point.

(3) A discharger may eliminate a sampling point established under subsection (1) or (2) if the sampling point is no longer necessary to permit the calculation of concentrations under sections 11 and 12 and the calculation of loadings under sections 13 and 14 for each limited parameter that accurately reflect the level of discharge of each such parameter from the plant.

(4) For the purposes of this section, except for subsection (6), a concentration for a parameter or a loading for a parameter 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 concentration or a loading that accurately reflects the level of discharge of the parameter from the plant.

(5) In determining what is necessary to meet a discharger’s obligations to establish sampling points under this section, except for subsection (6), the discharger shall consider both which streams should have sampling points and where on a stream a sampling point should be located.

(6) Each discharger shall, by July 12, 1995, establish a sampling point on each building effluent stream at the discharger’s plant, as necessary so that no building effluent is discharged from the plant to surface water without flowing past a sampling point.  O. Reg. 215/95, s. 7.

8. (1) By July 24, 1995, 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 July 12, 1995.

(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. 215/95, s. 8.

Use of Sampling Points Established under this Part

9. Except as permitted under sections 21, 23, 24 and 26, each discharger shall use the sampling points established under this Part for all sampling required by this Regulation.  O. Reg. 215/95, s. 9.

(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 11 to 15.  O. Reg. 240/07, s. 2.

(3) Each discharger shall ensure that each calculation of a concentration required by section 11 or 12 is performed as soon as reasonably possible after the analytical results on which the calculation is based become available to the discharger.  O. Reg. 215/95, s. 10 (3).

(4) Each discharger shall ensure that each calculation of a loading required by section 13, 14 or 15 is performed in time to comply with subsection 35 (4).  O. Reg. 215/95, s. 10 (4).
