The Idaho Legislature determined it was in the interest of the state and its citizens to establish a Department of Environmental Quality to carry out programs to protect human health and the environment, to enforce environmental laws, and to develop pollution, compliance assistance, and other environmental incentive programs (Idaho Code §39-102A(4)).  

Rules and guidance determine how DEQ, its partners, and regulated entities comply with state and federal laws to protect human health and the quality of Idaho’s air, land, and water.
