1. (1) In this Regulation, “assessment parameter”, in relation to a plant, means a parameter that is listed in the Table for the plant in Schedule 3; “blowdown water” means recirculating water that is discharged from a cooling water system for the purpose of controlling the level of water in the cooling water system or for the purpose of discharging from the cooling water system materials contained in the cooling water system the further build-up of which would impair the operation of the system; “cooling water effluent” means water and associated material that is used in an industrial process for the purpose of removing heat and that has not, by design, come into contact with process materials, but does not include blowdown water; “cooling water effluent monitoring stream” means a cooling water effluent stream on which a sampling point is established under section 8; “cooling water effluent sampling point” means a sampling point established on a cooling water effluent stream under section 8; “Director”, in relation to obligations of a discharger, means a Director appointed under section 5 of the Act and responsible for the region in which the discharger’s plant is located and includes an alternate named by the Director; “discharger” means an owner or person in occupation or having the charge, management or control of a plant to which this Regulation applies; “limited parameter”, in relation to a plant, means a parameter for which a limit is specified for the plant in Column 3 or 4 of the Table for the plant in Schedule 2; “pick-up”, in relation to a sample, means pick-up for the purposes of storage, including storage within an automatic sampling device, and transportation to and analysis at a laboratory; “plant” means an industrial facility and the developed property, waste disposal sites and wastewater treatment facilities associated with it; “process change” means a change in equipment, production processes, process materials or treatment processes; “process effluent” means, (a)  effluent that, by design, has come into contact with process materials, (b)  blowdown water, (c)  effluent that results from cleaning or maintenance operations at a plant during a period when all or part of the plant is shut down, and (d)  any effluent described in clauses (a) to (c) combined with cooling water effluent or storm water effluent; “process effluent monitoring stream” means a process effluent stream on which a sampling point is established under section 8; “process effluent sampling point” means a sampling point established on a process effluent stream under section 8; “process materials”, in relation to a discharger’s plant, means raw materials for use in an industrial process at the plant, manufacturing intermediates produced at the plant, or products or by-products of an industrial process at the plant, but does not include chemicals added to cooling water for the purpose of controlling organisms, fouling and corrosion; “quarter” means all or part of a period of three consecutive months beginning on the first day of January, April, July or October; “semi-annual period” means all or part of a period of six months beginning on the first day of January or July; “storm water effluent” means run-off from a storm event or thaw that is not used in any industrial process. O. Reg. 307/17, s. 1. (2) For greater certainty, this Regulation applies both to effluent streams that discharge continuously and to effluent streams that discharge intermittently. (3) An obligation on a discharger to do a thing under this Regulation is discharged if another person has done it on the discharger’s behalf.  O. Reg. 562/94, s. 1. Purpose
