The United States Army Corps of Engineers Tribal Nations Technical Center of Expertise (TNTCX) was established in order to provide a cost-effective administrative tool to improve USACE’s quality and effectiveness in delivering USACE missions and Federal Trust responsibilities to Federally recognized tribes. In that role, the TNTCX can engage with each of the 574 Federally recognized Native American Tribes, national and regional organizations representing Native American governments, Native American communities, and the USACE Commands serving those communities. The TNTCX program is vital to the successful management of our relationships with Tribal Nations, which helps us maintain and operate key infrastructure projects that contribute to the Nation’s economy, environment, safety, and quality of life - now and in the future.
