• Marginal note:Maintenance and calibration

  (2) The owner or operator of a wastewater system who has installed monitoring equipment must maintain and calibrate that equipment so that it may be used to determine the volume of effluent deposited via the final discharge point in accordance with, as the case may be, subparagraph 7(2)(a)(i) or paragraph 7(2)(b).
