Accident Classified As: No Information Given

Cause of Problem: No Information Given

The affected soil was identified through soil sampling beneath tank T-106, which was conducted to assess odors in the work area when the tank was elevated for maintenance. Upon sampling and analysis, it was determined that VOCs and Total Petroleum Hydrocarbons-Gasoline Range Organics (TPH-GRO) exceeded the RECAP Soil_SSi and Soil_ssgw. No soil staining, free phase material, or sheen was observed beneath the tank. The tank resides atop a clay lined foundation and ring structure which isolates the tank bottom from the surrounding soil and ground water. No removal was completed as integrity of the ring structure and cribbing could be compromised by adjacent soil removal.

Discharge Preventable - No Information Given

Notes/Remedial Actions

The site was investigated on 11/13/13 and odors were detected while lifting Tank 106. Samples of soil varying from 0-12 inches came back with levels of PPHGRO and Benzene above RECAP. Report does not mention specific quantities. On a follow up date sampling at 3 ft was conducted and nothing above RECAP was detected. No sheen or signs of league in or around the tank was observed. No removal was completed as integrity of the ring structure and cribbing could be compromised by adjacent soil removal. A work plan for Tank 106 soil and ground water assessment has been submitted to Remediation Services, dated 12/23/2013 and is viewable in EDMS.
