• Rules. Oregon operates its underground injection control (UIC) program through authorization from the U.S. Environmental Protection Agency (EPA). The Oregon Department of Environmental Quality (DEQ) has made it official policy to restrict the further construction and use of cesspools and sewage drain holes as a means of disposing of inadequately treated sewage or wastes in the state, particularly in the lava terrain of central Oregon. Most state wells are regulated via DEQ's Water Pollution Control Facilities (WPCF) permit program.
