The Montagne-de-la-Croix landfill site facilities have been designed according to the socio-economic, environmental and technical standards so that solid wastes are buried according to methods that are not harmful to the environment. Wastes that are buried at the site come from all over the territory served by the North West Regional Service Commission (NWRSC).
The NWRSC Solid Waste Service also accepts 50% of the wastes from the Valley Solid Waste Commission. The other 50% of their wastes are buried at the site operated by the South West Solid Waste Commission in Lawrence Station. Wastes from northern Maine, coming from the Frenchville, St-John Valley and Van Buren transfer stations, are also sent to the Montagne-de-la-Croix site, at an extra cost of $18 per tonne.
The Solid Waste Service operates under a fixed annual budget and additional volumes, such as those from Maine, help reduce the total cost per tonne for Canadian taxpayers.
