Client: Shell Oil Company
Project: Environmental Investigations & Transfer of Anacortes Refinery
Location: Anacortes, Washington

Background
In 1997, the Shell Oil Company began negotiations to sell its Anacortes Refinery. PGG assisted with this property transfer and continues to serve as an environmental consultant for the new owner.

Challenges
The refinery had been in operation for over 40 years; as such, it had a long environmental history, despite its highly favorable hydrogeologic setting, which generally discouraged contaminant migration.

Approach
During our 15-year association with this refinery, we have consulted on many environmental issues. Consequently, for this project, we leveraged on our historical knowledge of the area’s hydrogeology, RCRA permitting work and investigations, and long-term monitoring data for soils, pore water, and groundwater. One particularly useful tool in this property transfer was a Geographic Information System we developed to view the refinery’s hydrogeology in three dimensions, along with contaminant transport pathways such as utility corridors. This system also allows users to query and view environmental chemistry data.

Outcome
Our extensive institutional knowledge of the refinery’s environmental history proved valuable to this project. Shell described our contribution as a key element in the property’s smooth transfer.
