A petroleum leak was first found at the station’s Underground Storage Tank (UST) site in 2015 after a follow-up investigation years after the station’s closure in 2003. According to investigators and the Tri-County Times press release, the contents in the UST taken after the initial investigation surpassed the Department of Licensing and Regulatory Affairs (LARA) limits.
The investigation showed the surrounding soil and groundwater was contaminated and had migrated off-site. The settlement agreement concluded in May 2018 with the landowner responsible for resolving the cleanup obligations. Also, the agreement allowed the DEQ to initiate site cleanup and work began in September 2018.
Clean-up and restoration activities include removal of the UST’s and contaminated soil and asbestos building materials. In addition to removal, sheet piling will be installed to ensure that the excavation efforts do not damage roadways or pavement. The total removal, cleanup, and demolition will total $595,000. Once cleanup efforts conclude, the site will continue to be monitored for leak detection and soil contamination for a year after excavation. Once their initial investigation concludes, the DEQ will create a report documenting the release available in January 2019.Sources: https://www.tctimes.com/news/deq-cleaning-up-leak-at-old-fairbanks-gas-station/article_bf9ef8c2-dec7-11e8-a096-f70ddb84fe93.html http://lindenmi.us/index.php/news/216-remediation-at-former-fairbanks-marathon.html
