(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.

(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.
