Peatland Mining in Manitoba’s Interlake: Cumulative impacts analysis focusing on potential nutrient loading and greenhouse gas emissions

The analysis finds that potential nutrient loads from peat mining operations represent a small proportion of the yearly phosphorus and nitrogen loads to Lake Winnipeg, with total loads from all Manitoba lease holdings not exceeding 12 tonnes P yr-1 and 449 tonnes N yr-1. Greenhouse gas emissions from land-use change due to active mines in Manitoba are estimated not to exceed 13.47 tonnes CO2e ha-1 yr-1, with total emissions from all current lease holdings in the province not exceeding 0.4 million tonnes CO2e yr-1.

• Nutrient leaching from active peat mines in Manitoba is estimated to stay below 0.40 kg P ha-1 yr-1 and 15.00 kg N ha-1 yr-1. Total phosphorus and nitrogen loads to Lake Winnipeg from all current peat lease holdings in Manitoba are projected not to exceed 12 tonnes P yr-1 and 449 tonnes N yr-1, respectively, which constitutes a small proportion of the lake's total yearly loads.
• Greenhouse gas emissions resulting from land-use change for active peat mines in Manitoba are estimated not to exceed 13.47 tonnes CO2e ha-1 yr-1. The total emissions from all current peat lease holdings across Manitoba are projected to be no more than 0.4 million tonnes CO2e yr-1, while those specifically in the Interlake region would not exceed 0.17 million tonnes CO2e yr-1.
