The Shell Guam terminal needs to clean up its act before it is sold.
The US Environmental Protection Agency (EPA) has ordered Shell Guam to continue cleaning up hazardous waste at its terminal before it is sold to another
Shell Guam has been voluntarily cleaning up the facility for many years under US and Guam EPA oversight, but the impending sale has put pressure on the formality of the procedure.
Tristar Terminals Guam, which is jointly owned by Agility Defense & Government Services of Alexandria, Vancouver, and Dubai-based Tristar Transport, agreed to buy the operation from the Shell subsidiary in February.
Currently, we are satisfied with Shells response activities at the site, but with the impending sale of the facility, it is time to formalise clean-up responsibilities to ensure that site work continues into the future, Jeff Scott, waste management division director in EPAs southwest region, says.
Monitoring stations have found that groundwater beneath the terminal is contaminated with petroleum, benzene, toluene, and other petroleum constituents and additives.
The EPA says that while there are no drinking water supply wells in the immediate vicinity, groundwater generally flows to the ocean west of the site and can have impacts on the Tenjo and Big Guatali rivers. Nearby wetlands and the Big Guatali River also received surface discharges from the facility, it added.
EPA ordered Shell Guam to summarize current conditions and historic cleanup operations, develop and implement an investigation plan for the facilitys solid waste areas, submit a corrective measures study, and notify and respond to any identified immediate or potential new hazardous waste releases and implement any response actions.
