To ensure that any drinking water threat in the vicinity of a transport pathway ceases to be or will not become a significant drinking water threat; or that a transport pathway ceases to endanger the raw water supply of a drinking water system, municipalities have the following obligation under O. Reg 287/07 s. 27(3):

If a person applies to a municipality for approval of a proposal to engage in an activity in a wellhead protection area or a surface water intake protection zone that may result in the creation of a new transport pathway or the modification of an existing transport pathway, the municipality shall give the source protection authority and the source protection committee notice of the proposal and shall include a description of the proposal, the identity of the person responsible for the proposal and a description of the approvals the person requires to engage in the proposed activity.

Municipalities shall ensure that information on any proposals involving transport pathways are provided to the parties noted in the regulation (future activity).

Monitoring policy MP-20 applies.

MP-20: Municipalities should, within a reasonable timeframe after receiving a proposal that may involve a transport pathway, provide the necessary documents to the parties noted in O. Reg. 287/07 s 27(3).
