FACILITY INFORMATION
The Shell Oil Products US (OPUS) refinery is located at 8505 South Texas Road in Anacortes, WA. The refinery processes crude oil into a variety of petroleum products. It has the ability to process between 135,000 and 160,000 barrels of crude oil each day.
Oily Water Sewer
The refinery’s permit identified the oily water sewer as a solid waste management unit with potential for releases to soil and groundwater. Ecology is not aware of any current releases from the unit. The refinery will submit a plan for ongoing investigation of releases from the oily water sewer with corrective action, remediation, and monitoring, as needed. Contaminants of concern include metals, volatile organics, and semi-volatile organics.
West Impounding Basin
Hydrocarbons were discovered in the refinery’s West Impounding Basin in 1990. The facility installed a light non-aqueous phase liquid recovery system to recover the hydrocarbons from the groundwater. Since the startup of the system, groundwater monitoring takes place quarterly and samples are collected every six months. Other contaminants of concern include 15 metals, volatile organics, and semi-volatile organics.
