Biosolids Management Master Plan

Halton Region has initiated a comprehensive Master Plan Study for the management of biosolids generated by the Region's wastewater treatment plants (WWTPs).


Study initiated May 2009.


XCG Consultants Ltd./Tetra Tech

Study Purpose

The primary purpose of this study is to evaluate biosolids management alternatives and methods, and to recommend a strategy that responds to the current and future challenges through to the year 2031.

Study Process

The study is being conducted in accordance with the requirements for Master Plans under the Municipal Class Environmental Assessment (EA) (Municipal Engineers Association, 2007).

The Class EA process includes:

  • Public and review agency consultation.
  • An evaluation of alternatives and methods.
  • An assessment of the potential environmental effects of the proposed projects.
  • The identification of reasonable measures to mitigate any adverse environmental impacts.

The intent of the Master Plan is to:

  • Fulfil the Class EA requirements for Schedule B projects - those having a minimal environmental impact and require only a screening.
  • Complete Phases 1 and 2 of the process for Schedule C projects - those with a greater degree of environmental impact.

Projects identified as Schedule C undertakings will proceed to Phases 3 and 4 of the Class EA process following the completion of the Master Plan, which entails additional study and consultation.

Background Information

The 7 WWTPs owned and operated by Halton Region currently generate approximately 11,000 dry tones of anaerobic biosolids per year. In 1999, a Biosolids Management Strategy was undertaken which recommended program diversification and flexibility to address issues related to biosolids management.

Since that time there have been additional changes in the regulation of biosolids management, as well as biosolids treatment technologies. Given these changes, it is an appropriate time for the Region of Halton to undertake a Biosolids Master Plan that would consider specific program needs and long term sustainability.
