NELPCo is a partnership between the Na-Cho Nyäk Dun Development Corporation (NND-DC) and Tetra Tech Canada Inc. (Tetra Tech) and is recognized as an Aboriginal Business by the governments of Canada and the Yukon. NELPCo provides engineering and environmental services to both public and private sector clients focusing on mining, energy, community infrastructure, transportation, and development market sectors.

A primary goal of the partnership is to maximize environmental and engineering services, business, and employment opportunities in the traditional territory of Na-Cho Nyäk Dun First Nation (NND-FN).

The partnership has brought employment and training opportunities to NND-FN citizens, as well as profits to the NND-DC, which holds a majority interest in the limited partnership.

Since incorporation, NELPCo has successfully completed more than 50 projects for more than 20 clients. NELPCo has completed work for federal and municipal governments including agencies such as Yukon Government, First Nation of Na-Cho Nyäk Dun, Indigenous and Northern Affairs Canada (INAC), and the Village of Mayo; industrial clients including Alexco Resources, Victoria Gold Corporation, ATAC Resources, and Strata Gold; and various other private industry clients.
