Some of Our Services
Environmental Regulatory Compliance
In response to a growing concern for the environment, the National Environmental Policy Act of 1969 (NEPA) was passed and has become the national charter for environmental protection. It sets forth a process for analyzing and disclosing significant impacts of a proposed action. Because the majority of activities in Indian Country include Federal funding or approval, nearly all developments require some aspect of the NEPA process. Since tribes have retained their sovereignty for environmental protection on land within their jurisdiction, activities on tribal land often require the approval of both the tribal government as well as the relevant federal agency.
ETD Inc. is often involved in projects that require community outreach and public relations. For example, the National Environmental Policy Act of 1969 (NEPA), requires public scoping to develop an understanding of the public's issues, especially for controversial projects.

She also prepares land use plans that clearly articulate the communities' vision, priority projects and coordination efforts."
