Scientifically Based Plans

The Sudbury Source Protection Plan identifies potential threats (as defined in the Clean Water Act and described in the Assessment Report) to municipal sources of drinking water and prescribes policies, actions and programs to reduce or eliminate these threats. The Source Protection Plan was originally approved on September 19, 2014 and became effective April 1, 2015. Updates under Section 36 of the Clean Water Act, 2006 were completed with an effective date of March 16, 2021.

The Explanatory Document provides the intent and rationale behind the policy decisions made in the Source Protection Plan.
