The U.S. Department of Energy (DOE) seeks a change to Hanford’s Dangerous Waste
Permit to close the 207 A South Retention Basin (SRB). The basin is a concrete structure
used from 1977 through 1989 to store process condensate from the 242 A Evaporator
Facility. The basin has been empty since use of the facility ended in April 1989. DOE’s
closure process will include removal of the structure followed by sampling and analysis
of the soil to assure that cleanup levels have been met.

DOE is submitting the 207 A SRB closure plan for public comment. This closure plan will
be processed as a Class 3 modification to the permit. Class 3 permit changes call for a 60
day comment period on the proposal led by the permittee (DOE), and a public meeting.
This will be followed at a later date by an Ecology 45 day comment period on the
draft permit change.

To allow the work to be completed in this fiscal year, DOE plans to submit a Temporary
Authorization request to Ecology.

The DOE/RL contact person for this permit change is Kris Skopeck, 509-376-5803. The
Department of Ecology contact person is Nina Menard, 509-372-7950.
Copies of the proposed closure plan and supporting documentation are available at the
Administrative Record, 2440 Stevens Drive, Richland, WA or online
http://pdw.hanford.gov/arpir/

The permittees’ compliance history during the life of the permit being modified is
available from the Washington State Department of Ecology contact person.
