Historical Resources Impact Mitigation
註釋During the summer of 1994, Bison Historical Services Ltd. (BHSL) completed excavations at two sites along the proposed NPS 48 Eastern Alberta System M/L Loop #3 (Matzhiwin Section). The work was done for NOVA Gas Transmission Ltd. (NGTL) prior to construction of the pipeline in response to a previously completed Historical Resources Impact Assessment (NRIA).
