Since 2010, ITEP has delivered the TLEF: a joint effort between the Institute for Tribal Environmental Professionals (ITEP), the Tribal Waste and Response Steering Committee (TWAR SC), and US EPA’s Office of Land and Emergency Management (OLEM). The ninth annual forum took place in 2019 for environmental professionals from Tribes, US EPA, State/Local/Federal agencies, community organizations, and other interested parties to meet, share knowledge and learn from one another how to improve management and protection of Tribal lands and human health.
