Navajo Nation EPA

The Navajo Nation Environmental Protection Agency (NNEPA) was created in 1994, but its enabling legislation's, the Navajo Nation Environmental Protection Act, was not approved by the Navajo Nation Council until April 21, 1995. Before becoming NNEPA, the organization was known first as the Navajo Tribal Environmental Protection Commission, then as the Environmental Protection Administration. The Navajo Nation Council in 1972 recognizing the importance of environmental protection established the initial commission.

The NNEPA organization is subdivided into four departments. Those Departments are: Surface and Ground Water Protection Department, The Waste Regulatory and Compliance Department, The Air and Toxics Department, The Enforcement Department.

Today, NNEPA consists of over sixty-five (65) staff members, with expertise in compliance inspections, permit review and renewal, legislative rule making, criminal enforcement, and environmental review
