Additional information received via email 2022-04-05 from Travis Perkins (tperkins@ntpc.com). Spill report updated by ECCC NEEC DGW "I am just wanting to provide updated volumes for the NTPC spill 2022082. We now estimate that 4400 L was released within the plant, and that approximately 1762 L remained in the plant. Clean up efforts of free-standing product have been completed and 15 totes of snow and ice and 7 mega-bags of saturated insulation have been removed. At current, the risk of migration is very low and interceptor trenches and berms are being installed to further prevent migration until soil thaws and more soil is able to be removed. "
