Connecting WM's RNG production complex in Sainte-Sophie to the existing gas network
WM, North America's largest waste management company, and Énergir are collaborating on the largest renewable natural gas (RNG) production project to date in Quebec.
Once purified, all the biogas extracted from WM's Sainte-Sophie landfill and biomethanization plant will be injected into Énergir's gas network through a dedicated 10 km pipeline connecting WM's facilities to the network in Mirabel.
This project benefits from $14,708,040 in financial assistance from the ministère de l’Économie, de l’Innovation et de l’Énergie, as part of the Programme de soutien à la production de gaz naturel renouvelable (PSPGNR), which comes from the Fonds d’électrification et de changements climatiques, a special fund entirely dedicated to addressing climate change, enabling the implementation of the 2030 Plan for a Green Economy.

Construction of the renewable natural gas pipeline and infrastructure to connect WM's facilities will begin in September and continue until early winter. Keep up to date with construction progress by subscribing to our mailing list by clicking here.
The project at a glance
Ultimately, the projects will inject up to 68 million cubic meters of RNG into Énergir's network. The RNG from WM's Sainte-Sophie facility will thus make a significant contribution to achieving the government's and Énergir's target of distributing 5% RNG in the gas network by 2025.
The WM and Énergir projects could also significantly reduce Quebec’s fossil GHG emissions by nearly 129,000 tonnes of CO2 equivalent, by replacing traditional natural gas.
The projects involve the construction of a plant to process biogas from the technical landfill and the biomethanizer to refine it into RNG, a 10 km high-pressure pipeline and an injection station to connect WM's facilities to the existing gas network.
To keep on schedule, workers will be on site Monday to Saturday, from 7 a.m. to 5 p.m. Soils will be restored to their original state as work progresses, but depending on weather conditions, it is possible that part of the restoration will be postponed until spring 2025.
Although the vast majority of the worksite is located away from traffic lanes and residences, considerable efforts are being made to mitigate impacts on local residents.

Preliminary schedule
Authorizations
The construction of the connection was subject to rigorous and thorough examination by various regulatory bodies:
- Commission de protection du territoire agricole du Québec (Decision 440749)
- Bureau d'audiences publiques sur l'environnement (Report 373)
- Régie de l'énergie (Dossier: D-2024-053)
- Government of Quebec ( Order-in-Council 1042-2024)
- Ministère de l'Environnement, de la Lutte contre les changements climatiques, de la Faune et des Parcs (To come)
Environmental impact assessment and review procedure
In compliance with the process set out in the la Loi sur la qualité de l’environnement, Énergir submitted the project's Environmental Impact Assessment (EIA) to the Ministère de l'Environnement et de la Lutte contre les changements climatiques, de la Faune et des Parcs (MELCCFP) in December 2022.
The Bureau d'audiences publiques sur l'environnement (BAPE) was then mandated to hold a public hearing, following which the BAPE commission concluded in its report that the project should be authorized. (Read the BAPE report)
After analyzing the BAPE and MELCCFP reports, and following the Minister's recommendation, the Quebec government authorized the project by decree (Order-in-Council 1042-2024, July 3, 2024).
Community’s information and consultation process
From the beginning of the project, we wanted to make information on the project accessible in order to understand the concerns of the community regarding the project in order to consider them throughout the development.
