Basic Information

Compliance with the nation’s environmental laws in Indian country is the ultimate objective; enforcement is a vital part of encouraging governments, businesses and other companies who are regulated to meet their environmental obligations. EPA provides compliance assistance, conducts compliance monitoring, and pursues enforcement in areas that yield the most environmental benefit and/or reduce risk to human health.

EPA works with federally-recognized Indian tribes on a government-to-government basis and recognizes the right of Indian tribes to self-government in the implementation and administration of environmental programs.

In November 1984, Administrator William Ruckelshaus signed the EPA Policy for the Administration of Environmental Programs on Indian Reservations.

Information resources contains additional policies regarding relationships with tribes in the compliance assurance and enforcement context.
