Notice of determination

Québec - March 06, 2023 – Indigenous Services Canada has determined that the proposed project Increase of the drinking water reserve – Manawan is not likely to cause significant adverse environmental effects.

This determination was based on a consideration of the following factors:

• technically and economically feasible mitigation measures.

Main mitigation measures taken into account for this determination are:

• ensure that vehicles are in good working and don't let the engine idle unnecessary;
• limit intensive construction activities before 7:00 a.m. and after 7:00 p.m.;
• provide an oil spill emergency kit at all times at machinery storage and refuelling areas;
• place drums and containers containing hydrocarbons or other hazardous products in a bin or between berms that can collect 125% of the volume of the stored reserves;
• avoid deforestation between April 30 and August 31 to protect migratory bird nesting. If unavoidable, check for nests in trees at all times;
• keep machinery away from water bodies, watercourses and wetlands;
• avoid working during heavy rainfall which could generate significant flow in intermittent streams;
• Install still fences;
• Develop a drinking water source protection plan;
• Monitor groundwater quality in observation wells three times a year for at least 3 years.

Indigenous Services Canada is satisfied that that the carrying out of the project is not likely to cause significant adverse environmental effects.

Therefore, Indigenous Services Canada may carry out the project, exercise any power, perform any duty or function, or provide financial assistance to enable the project to be carried out in whole or in part.
