If the holder determines that water treatment equipment or operational check equipment at a drinking water system may be bypassed, or discovers any other problem with the drinking water system that, in his or her opinion, may lead to improperly treated water being delivered to users of the drinking water system but does not constitute a failure to comply with Schedule 2, 6, 8 or 9 to the Drinking Water Systems Regulation, he or she shall include in the report a description of the problem, together with recommendations that would rectify the problem or mitigate risks associated with it. 16. If at any time during the assessment of the drinking water system or the preparation of the report the holder determines that the drinking water system does not comply with a requirement in Schedule 2, 6, 8 or 9 to the Drinking Water Systems Regulation and that the lack of compliance may lead to improperly treated water being delivered to users of the drinking water system, he or she shall immediately inform the owner of the drinking water system in writing of the fact, identifying those provisions of the Drinking Water Systems Regulation with which the drinking water system does not comply and the problems that need to be resolved, and recommending changes that would bring the drinking water system into compliance. 17. If the holder makes the determination described in paragraph 16, the holder shall not complete the report, subject to paragraph 18. 18. If the owner of the drinking water system notifies the holder in writing that the changes recommended under paragraph 16 have been made, the holder shall review the changes, and if, in the holder’s opinion, the altered drinking water system is in compliance with Schedules 2, 6, 8 and 9 to the Drinking Water Systems Regulation, the holder shall complete the report. 19. On completing a report, the holder shall promptly sign and give to the owner of the drinking water system a declaration, in the form provided for the purpose by the Ministry of the Environment, containing the opinion of the holder that is required to be provided for the purposes of clause 21-5 (b) of Schedule 21 to the Drinking Water Systems Regulation.
