The National Environmental Policy Act (NEPA) of 1969 established a national policy addressing the effect of human activities on the natural environment, particularly the influences of population growth, resource exploitation, and urbanization, while also recognizing the vital importance of protecting and maintaining environmental quality. CNEP staff conducts formal environmental review records (ERR) to examine the potential negative or beneficial effects that are associated with activities such as rehabilitation, utility expansion, land acquisition, and new construction. These ERRs are conducted in accordance to NEPA as well as regulations established by the US Department of Housing and Urban Development, the US Department of the Interior, and the US Department of Health and Human Services.
