We make every effort to ensure the data presented here is accurate based on the best available information currently on file with DEC. It is therefore subject to change as new information becomes available. We recommend contacting the assigned project staff prior to making decisions based on this information.


On November 20, 2009, crude oil-contaminated soil was discovered during a construction project beneath the pipe headers at the West Metering Building at the Valdez Marine Terminal. An immediate response was conducted and additional effort is planned for 2010. This is believed to be a historic release.

11/29/2010 Report or Workplan Review - Other Date of receipt of Valdez Marine Terminal West Metering Spill Remediation Report. Review included Laboratory Data Review Checklist. In July and August of 2010, about 238 cubic yards of contaminated soil was removed. Extent of excavation was limited by bedrock. One confirmation sample exceeded ADEC most conservative criteria. Benzene was found at 0.148 mg/kg. Aquazyme was added to the excavation before it was backfilled. Prior to excavation, test pits were advanced to determine the extent of contamination and to further characterize the site. There were data quality issues with benzo(a)pyrene and anthracene, however a request for additional information from the laboratory showed that MS/MSD non-client samples had acceptable recoveries for these compounds. Also, downgradient surface water monitoring has not detected these compounds (groundwater daylights repeatedly as surface water before leaving the VMT). Also, methylene chloride was reported by the laboratory in some test pit samples as above the DL but below the LOQ and therefore was J flagged as an estimated result. The laboratory is currently not able to meet our cleanup levels and these results are above cleanup levels but not likely to really be COPCs. These factors in combination with the fact that the confirmation samples were also mostly non-detect, some present at very low levels and only one above the most conservative criteria for benzene only - leads me to conclude that this site may still be a candidate for a CC with ICs.

1/10/2011 Cleanup Complete Determination Issued Contaminated Sites staff has completed a review of the environmental records associated with Alyeska VMT West Metering Building site located at the Valdez Marine Terminal in Valdez, Alaska. Based on the information provided to date, it has been determined that the contaminant concentrations remaining on site do not pose an unacceptable risk to human health or the environment and no further remedial action will be required as long as the site is in compliance with established institutional controls (ICs). Keather McLoone
1/12/2011 Institutional Control Record Established Institutional Controls established and entered into the database. Keather McLoone
12/1/2011 Update or Other Action The current project manager chose to retain management of this site with the Cleanup Complete Determination that has Institutional Controls. Kristin Thompson
1/14/2013 Institutional Control Periodic Reporting Alyeska continued to use this facility as of 1/14/2013, so assumptions of site closure have not changed. Richard Bernhardt
11/6/2013 Institutional Control Compliance Review Staff changed from Richard Bernhardt to IC Unit. IC compliance review conducted. Reminder system set-up to follow-up with the responsible party in 2016. Kristin Thompson
1/7/2016 Institutional Control Compliance Review We received verification from Alyeska Pipeline Service Company in writing that land use for this property has not changed. The reminder system has been set to do another compliance review in 2021. Evonne Reese
