Common use of Tesoro Alaska Pipeline Clause in Contracts

Tesoro Alaska Pipeline. The pump station for the Tesoro Alaska Pipeline is adjacent to the Kenai Refinery Lower Tank Farm. Multiple historic tank and buried pipeline releases have impacted soil and groundwater in the area; however there are no documented releases from the pipeline pump station. The soil and groundwater surrounding the pump station is considered characterized and undergoing groundwater monitoring and treatment. • A pipeline release in 2001 resulted in soil, groundwater and surface water impacts in an undeveloped area of the Kenai Peninsula. The quantity of the release is not known. Soil surrounding the release was excavated and stockpiled at the Kenai Refinery while groundwater and surface water were remediated on-site. The Alaska Department of Environmental Conservation issued a No Further Action letter for this cleanup effort in 2008. There are no other known release sites on the pipeline between the Kenai Refinery and Anchorage. • Historic spills and releases have impacted the Anchorage #1 terminal, including past releases from the Tesoro Alaska Pipeline receiving station. Groundwater remediation monitoring is ongoing across the Anchorage #1 terminal. In addition, a soil vapor venting system is being installed to address a flame suppressant compound detected in soils near the receiving station control room. None Area of significant groundwater and soil impacts: (1) lower tank farm groundwater impact source area including 1988 jet fuel release and unknown light products release in area of Tank 63, (2) process unit historic releases from oily water sewer system including releases from failed grout in subsurface sewer hubs, (3) groundwater issues generally 35 to 40 feet below ground surface and groundwater impacts in three water-bearing zones below refinery and off-site and (4) possible contributor to refinery-wide groundwater impacts.
