Problems/Comments
On January 6, 2015 the U.S. Forest Service (USFS) reported to DEC encountering petroleum-contaminated soil in the DOT right of way under a culvert draining the USFS Cascade Creek Facility at 2108 Halibut Point Road in Sitka. The excavation was exploratory in preparation for a sewer and other renovations to the facility. DEC approval was given to return the contaminated soil to the excavation with the condition that the location was marked and investigated for an upgradient source on USFS land when the culvert is removed in spring 2015. DEC's consultation with USFS led to the determination that the source, although unidentified, is most likely not from an active release. Later the same month, on January 20, 2015, the USFS reported that a contractor working on the USFS Cascade Facility renovation project encountered an additional area of soil contamination apparently from a historic release of diesel fuel in an area southeast of the fuel/paint shed, near a fuel tank. Approximately 2 cubic yards of contaminated soil were excavated and DEC staff advised the USFS to: not put the contaminated material back into the excavation; store the contaminated soil in a temporary storage cell – 10mil or greater poly liner material under the soil and cover it with 10mil or greater poly to keep water off of it; have a qualified third party environmental consultant take confirmation samples at the area the contamination was found – from the bottom and the side walls; if they want/need to backfill the area to take confirmation samples as noted above and cover the area with a minimum 10mil liner material to delineate the area of contamination from the clean backfill; if additional discrete, unconnected areas of contaminated soil are encountered, USFS and its contractors should follow the same procedure – all contaminated soil encountered can be stockpiled in one lined and covered stockpile - with one caveat: if obviously different contamination is encountered USFS may make separate stockpiles so as to not co-mingle different types of contamination.

| 1/30/2015 | Site Added to Database | A new site has been added to the database | Mitzi Read |
| 4/2/2015 | Potentially Responsible Party/State Interest Letter | DEC letter was prepared and sent by electronic and regular mail today to the US Forest Service (USFS), owner/operator of the Cascade Creek Facility in Sitka, Alaska (State). The letter provides the USFS with notice of environmental contamination, notice of liability for the costs of the State providing cleanup oversight, and notice of cleanup responsibility. Although informal discussion of work plan design with the USFS has established an mutual understanding, the DEC letter provides a formal request that the USFS submit a sampling work plan for approval before any site work begins. The purpose of the letter is to ensure the pollution is contained and that the migration of contamination is not presenting a risk of exposure that could affect human health and safety or the environment. | Bruce Wanstall |
| 6/5/2015 | Meeting or Teleconference Held | Meeting held today in the DEC/CS Juneau office with Mike Wilcox from the USFS to discuss the physical attributes of the Sitka facility site, preliminary field and laboratory data on site media, contaminated soil screening and removal criteria, and department guidance for remedial options to manage lightly contaminated soil on-site. | Bruce Wanstall |
| 3/25/2016 | Meeting or Teleconference Held | DEC met with USFS Engineer Mike Wilcox to discuss a draft report compiling environmental information on the characterization and cleanup at the site in 2015, submitted this date. | Bruce Wanstall |
| 9/29/2016 | Document, Report, or Work plan Review - other | DEC evaluated and approves the interim report Final Site Characterization Report, US Forest Service Cascade Creek Facility, Tongass National Forest, Sitka, Alaska, with comments and requests for additional site characterization of three areas at the facility. The report narrowed the scope of future work at the site and contributed to what is known at the site. Complete exposure pathways for current receptors included ingestion of surface and subsurface soil, dermal absorption of soil contamination, and dermal absorption of groundwater. The groundwater pathway would only be encountered during construction activities as it is not currently used at the site. Additionally, inhalation of indoor and outdoor are pathways are considered complete, and pose an insignificant risk due to the contaminant levels detected in soil and groundwater. | Bruce Wanstall |
