Clear, well written laws are often needed to effectively manage ongoing environmental issues within Indian Country. Many tribes currently need to create or revise water, waste, air, or other environmental codes to address the unique issues and objectives within their community. This session provides a summary of a step-by-step approach to developing tribal environmental codes regularly taught in multiday workshops by Josh Simmons on behalf organizations such as the Institute of Tribal Environmental Professionals (ITEP). Examples will be drawn from the Josh’s work as Director of the Santa Ynez Chumash Environmental Office and as an attorney. In addition, Bill Nelson will share his experience in developing waste code for the La Jolla tribe, and his learnings from the recent ITEP Waste Codes Development workshop he participated in this past September.
