Narrative
While conducting the annual inspection of below-grade isolation gaskets on the tank 1283 tank valve, high lel levels were received. A shallow hole was hand-dug around the valve, showing a slight indication of a release. The area was further excavated, contaminated soil was removed, and diapers were placed under each flange and the flanges/diapers were wrapped in plastic. After a 24 hour test, the diapers around the line side flange for the tank valve were wet from product. The next 24 hours, the diapers were dry around that same flange. Initial measurements were taken and the flange did not seem out of alignment, however, when the flange was broken the gap on the top side of the flange was .5 inches greater than the bottom side of the flange. This resulted in the gasket not fully sealing and a 4.13 gallon release, based of the diaper and soil contamination. The line was further excavated to bring the flange into alignment and additional supports were placed under the tank line to prevent settlement.
