Is a DEQ permit required for dry wells, sumps, and other underground injection control systems (UICs)?
All underground injection control (UIC) systems are required to register with the Department. UIC systems include, but are not limited to, onsite sewage systems with a capacity to serve more than 20 persons a day, dry wells, sumps, and waste disposal wells. In addition to the registration requirement, some UICs need to be permitted. A permit is required if the UIC is not allowed outright by Oregon Administrative Rule (OAR) 340-044. For example, stormwater runoff to UICs may be allowed without a permit if the conditions of OAR 340-044-0050 are met. However, most wastewater discharges to UICs require a Water Pollution Control Facilities permit. Please visit the UIC web site for more information.
