Regulation Changes For Treated Septage As A Nutrient On Agricultural Land

Regulation changes 

On January 1, 2011 the Ministry of the Environment and the Ministry of Agriculture, Food and Rural Affairs (OMAFRA) put new rules and guidelines into effect for applying non-agricultural source materials (NASM) to farmland. This change was designed to strengthen the rules and remove overlapping approval processes for farmers and generators of NASM.

Under these new rules, treated septage to be used as a nutrient on agricultural land is treated as a nutrient under the Nutrient Management Act. Previously, it was considered a waste under the Environmental Protection Act.

Please see the chart below for how this change specifically impacts septage handlers

Developing new septage treatment options 

Since 2004, the ministry has been working cooperatively with its provincial partners, the Ontario Association of Sewage Industry Services, the University of Guelph and municipalities to develop cost effective septage treatment/management options. This includes several pilot projects and studies which supported the development of standards for treated septage and screening of septage.
The pilot projects and studies include treatment of septage by alkaline stabilization, geomembranes, reed beds and in lagoons.

Reports or links for other pilot projects and studies will be posted as they become available.
