NAEPC began its border activities with a Border XXI grant. In July 2004, NAEPC became the Tribal Liaison for California Border Tribes. NAEPC hosts Tribal Border Caucus Meetings as funded to enable tribes on both sides of the US-Mexico Border an opportunity to discuss their environmental concerns. NAEPC also compiled the Border 2012 reports and now compiles the Border 2020 Report, when there is a National Coordinators Meeting. If there is no meeting NAEPC contacts the tribes to determine concerns and issues to highlight in a brochure. The full Tribal Accomplishments and Issues Report is presented at the National Coordinators Meeting when they are held.
