Event: Public Comment Period on Proposed Updates to Permit for Hanford Dangerous Waste Management Units
Category: Comment Period / Feedback Opportunity
Event Date: March 25 – May 23, 2013

The U.S. Department of Energy Richland Operations Office (DOE-RL) is holding a 60-day comment period (March 25 through May 24, 2013) on proposed Class 2 modifications to the Hanford Facility Dangerous Waste Permit. These changes involve the Liquid Effluent Retention Facility and 200 Area Effluent Treatment Facility (LERF/ETF), and the Integrated Disposal Facility (IDF).
Proposed Class 2 modifications involve Treatment, Storage, and Disposal (TSD) units in Part III (Unit-Specific Conditions for Operating Units) of Hanford’s Dangerous Waste Permit. The proposed modifications include updates to tank volumes based on new engineering calculations and changes to emergency pumping procedures at the LERF/ETF. The proposed modification at IDF involves a change to the monitoring schedule for the leak detection system. IDF has not received waste for disposal and is now being monitored.

LERF & 200 Area ETF is a waste water storage and treatment system in the 200 East Area (in the center of the Hanford Site). The system receives process waste water from the 242 A Evaporator, 200 West Area groundwater, and other Hanford remediation and waste management activities. The LERF consists of lined surface basins. Waste water from LERF is pumped to ETF for treatment in process units that remove contaminants.

The IDF) is a permitted, lined landfill in the 200 East Area (in the center of the Hanford Site) for disposal of mixed low-level and low-level waste from Hanford cleanup activities. The IDF has not received any wastes to date.
The permittee’s compliance history during the life of the permit being modified is available from the Washington State Department of Ecology contact person, Ron Skinnarland at (509) 372-7924or Copies of the proposed permit modification and supporting documentation are available at the Administrative Record, 2440 Stevens Drive, Richland, Washington, or at
