Stormwater UIC System Requirements

The federal Underground Injection Control (UIC) program, enacted in 1974 under the Safe Drinking Water Act (SDWA), is administered by the Oregon Department of Environmental Quality (DEQ) and is intended to protect groundwater resources from contamination. Stormwater UIC systems are any man-made design or structure which allows discharge of stormwater below ground. Common UIC systems include, for example, dry wells, soakage trenches, and infiltration galleries. A UIC must be approved by the DEQ through Authorization by Rule (AR) or under an individual Water Pollution Control Facilities (WPCF) permit. Requirements for obtaining AR, operating a UIC or closing a UIC are set forth in Oregon Administrative Rules (OAR) 340-044-0005 through 340-044-0055.
