CommTank provided this removal service for a 500-gallon underground storage tank (UST) at 251 Mason Road Townsend, Ma. Pelletier Properties LLC was working at this bank owned property and discovered a 500-gallon UST. The tank needed to be pumped out immediately. The contractor obtained all the permitting and needed 6" of sludge/oil removed from the tank. The tank was intact when it was pulled from the ground and no holes or leaks were found.
