An industrial client contacted Braun Intertec to help resolve a petroleum storage tank (PST) discrepancy. During the course of a large-scale cleanup of metal-contaminated soil under the Voluntary Cleanup Program (VCP), the client had been notified by TCEQ that a release determination involving a diesel tank in 2005 was incomplete since the piping had not been removed. This incomplete release determination had the potential of holding up a VCP certificate of completion for several months. Furthermore, it was found that two unrelated PST removals at the site had been linked together in TCEQ’s database, further complicating the VCP closure process.

A waiver to the 30-day construction notification was filed and approved, and excavation of the diesel product lines began. Initial confirmation samples showed polycyclic aromatic hydrocarbons (PAHs) to exceed PST Program Action Levels. Excavation of soil impacted with total petroleum hydrocarbons (TPH) and PAH compounds continued until final soil confirmation samples were below applicable target levels. Excavated soil was manifested and transported off site for disposal. Braun Intertec / W&M filed a release determination report and provided TCEQ with depth to water and chemical data from nearby groundwater monitoring wells installed during the affected property assessment. The groundwater data demonstrated that groundwater was not impacted with TPH or PAHs above action levels or threatened by the release. TCEQ concluded that a release had occurred but that no further action was necessary.
In less than two months, Braun Intertec was able to complete the release determination and obtain a no further action letter from the TCEQ. In addition, a no further action letter was obtained for the other, unrelated PST removal. This allowed the client to proceed with closure under VCP without delay.
