Problems/Comments
In 1995, six test pits were advanced in a site assessment for a closure by removal of regulated underground storage tanks (USTs) and petroleum contamination of soil was identified. Although 524 tons of contaminated soil was recovered during the excavation to remove the USTs, the limits of impacted soil were not found in the interim removal action. Release investigation found that concentrations of gasoline and diesel hydrocarbon fractions in soil at the limits of excavation were an order-of-magnitude above migration to groundwater cleanup screening levels. The concentration and proximity of the residual soil contamination to the southern property line indicated that petroleum could be migrating off-site but groundwater was not investigated for contamination. For more information, see site file 1513.38.100.

| 6/17/2015 | Potentially Responsible Party/State Interest Letter | DEC sent by electronic mail to the City and Borough of Juneau Director of Finance, a standard notification of liability for the contamination identified at the CBJ – Capital Transit Bus Barn site located at 10099 Bentwood Place in Juneau. Because CBJ is documented as the current managing owner/operator of the site, CBJ is identified to be financially responsible or liable under AS 46.03.822 (Strict Liability for the Release of Hazardous Substances) for the investigation and cleanup of any hazardous substance contamination that might be present. Consultant for the CBJ, Carson Dorn Inc., plans to submit a site investigation work plan for the Site in 2015 for DEC approval. The effort is ongoing phased-approach project to complete the cleanup process for these last few of many petroleum release events that began in the late 1990s with decommissioning the CBJ underground tanks. | Bruce Wanstall |
