The presentation will be on how to use EPA's Enforcement Compliance History Online (ECHO) data tool to access data on regulated facilities on Tribal lands. This information can be used to better understand EPA's Direct Implementation responsibilities in Indian Country. Data from ECHO is also used by General Assistance Program (GAP) project officers and Tribal counterparts when developing or updating EPA-Tribal Environmental Plans (ETEPs) to identify regulated facilities on Tribal lands and EPA's related direct implementation responsibilities, and can also be used to identify programs Tribes may want to take delegation for. The presentation will also identify Direct Implementation Tribal Cooperative Agreements (DITCAs) as an opportunity for Tribes to become involved in program implementation without having to take sole responsibility for implementing the program. By using ECHO, Tribes can determine if a direct implementation program that is eligible for a DITCA is located within their boundaries.
