Several states have published specific guidelines to remove or appropriately close in-place underground storage tanks (USTs). According to the Massachusetts Department of Environmental Protection’s (DEP) UST Closure Guidance Manual, “when any UST is permanently closed (removed or closed in-place), Massachusetts law requires that an assessment be performed to determine if contamination is present in the environment.”
While the presence of contamination can be confirmed by visual and olfactory observations, the absence of visual and olfactory signs of a release are not clear indications that the Site is free from contamination. Analytical data is necessary to rule out contamination at a UST closure.
PES Associates’s Underground Storage Tanks Removal Service:
Our experienced staff of environmental scientists, geologists, hydrologists, and project managers play a critical role in the removal and/or closure process. Providing direction to licensed contractors is a key element in the implementation of sound engineering practices during UST closure activities. If contamination is encountered, we take a pro-active role (upon Client approval) in assessing the most cost-effective approach in managing and removing contaminated media.
