UNDERGROUND STORAGE TANK IOON-SS-28 CLOSURE
Enclosed are the completed Permanent Closure/Change-In-Service Checklist and
the Site Check/Site Assessment Checklist (two copies) for underground storage
tank 100N-SS-28, which was permanently closed (removed) on July 17, 1991.
These checklists are submitted in accordance with the requirements of
WAC 173-360-630 (12).
The tank which was previously emptied and rinsed has been transported to the
100-B Area where it is awaiting final disposal (salvage). The remaining
system piping (two lines approximately ten feet long) and pumps are being
scheduled for removal. As far as can be determined, no product remains in
these lines.
If you have any questions or require additional information, please call
Mr. Eric Goller at (509) 376-7326.
