The U.S. Department of Energy, Richland Operations Office (DOE-RL) is holding a 60-day comment period from February 19 through April 15, 2013 on a proposed modification to the Hanford Facility Dangerous Waste Permit. This Class 2 modification involves the 183-H Solar Evaporation Basins Treatment, Storage, and Disposal unit (TSD unit). These basins were removed and closed in the mid-1990s. The proposed permit modification would allow replacement of a groundwater well that is being used to perform post-closure monitoring. DOE-RL is proposing to replace a groundwater monitoring well (199-H4-3) that is blocking access to the 100-H Area where waste site remediation is required. The proposed replacement groundwater monitoring well (199 H4-84) is at the location of the removed basins. The existing monitoring well (199-H4-3) would be decommissioned under Washington State regulations before waste site remediation begins. This well replacement requires modification to the Part VI groundwater monitoring permit requirements for the 183-H Solar Evaporation Basins. For information on permit compliance history, contact Ron Skinnarland, Washington State Department of Ecology at (509) 372-7924 or Hanford@ecy.wa.gov. Copies of the permit modification request and supporting documentation are available at the Administrative Record, 2440 Stevens Drive, Richland. The 183-H Solar Evaporation Basins modification is available in the Administrative Record, www5.hanford.gov/arpir/.
