Pollution Prevention Control Plan Update Study

Background

The City of London is developing an updated Pollution Prevention Control Plan (PPCP). The PPCP will be a 5-year action plan that outlines remediation activities and strategies to proactively manage the wastewater system in London, while demonstrating that the wastewater system meets the requirements set out by the Ministry of the Environment, Conservation, and Parks.

The project will:

  • Identify an effective management strategy to limit the volume and frequency of untreated wastewater discharges into the Thames River and receiving streams
  • Review the Phase 3 of the 2018 PPCP Implementation Plan to identify areas of improvement and address future needs
  • Consider options for how the frequency and volume of sewer system overflows can be reduced
  • Incorporate a cost-benefit analysis to support prioritization of pollution source reduction options
  • Evaluate projects and programs to maximize benefits, feasibility, and participation of the public
  • Align potential servicing strategies to meet the Province of Ontario’s requirements for the proper treatment of wastewater (F-5-5)
  • Engage the public and First Nations communities in the development of the updated action plan
