In 1992, Congress passed the Indian Environmental General Assistance Program Act. This act authorized the U.S. Environmental Protection Agency (EPA) to provide General Assistance Program (GAP) grants to federally recognized tribes and tribal consortia for planning, developing and establishing environmental protection programs in Indian country, and for developing and implementing solid and hazardous waste programs on tribal lands. The goal of the GAP is to assist tribes in building capacity to administer tribal environmental programs consistent with the federal laws the EPA is charged with implementing, according to their individual needs. The program funds a range of activities and projects. As much as possible, the attempt has been made to highlight the activities in this guide that are eligible for support through the program, including those that have an approved Quality Assurance Project Plan (QAPP).
