OAK RIDGE NATIONAL LABORATORY MANAGED BY MARTIN MARIElTA ENERGY SYSTEMS, INC. Dr. Ronald 0. Hultgren, Deputy Assistant Manager Energy Research and Development DOE Oak Ridge Field Office Post Office Box 2008 Oak Ridge, Tennessee 37831-6269 POST OFFICE BOX 2008 OAK RIDGE, TEM S SEE 37831-8198 Notification of Planned Radiotracer Study - Oak Ridge National Laboratory WaLker Branch This letter notifies the Department of Energy (DOE) that research personnel at the Oak Ridge National Laboratory (ORNL) plan to release small amounts of radiotracers into Walker Branch. The purpose of the planned release is to determine the effect of hydrologic backwater zones on biological uptake and cycling of phosphorus in the stream. While this release is not a wastewater discharge and the amount of radiotracers involved is small, notification of the release to the Tennessee Department of Environment and Conservation (TDEC) is prudent. The radiotracers used will include approximately 5 millicuries ( m a ) of tritium as water (H20) and approximately 1.5 mCi of phosphorus-33 (P-33) as phosphate. The radiotracers will be released over a period of 1.5 hours. The approximate radiotracer concentrations, based on a stream flow of 6 liters/second (L/s) in Walker Branch, are described below. Radiotracer concentrations in Walker Branch, as the plume leaves the Oak Ridge Reservation under Bethel Valley Road, will be only slightly above background concentrations. In-Stream, at the Point of Release In-Stream, before Walker Branch goes- under Bethel Vallev Road Human Subjects Project

All personnel involved in the studies will be trained in the safe use of radionuclides, will wear appropriate protective clothing, and will be monitored by a health physicist during the experiment. This study will be conducted in late June unless notified otherwise. Monday, June 22, 1992, is the target date for the study, but the exact date will depend on weather and stream flow conditions. Please forward this information to TDEC at the following address.
