Action Information

Action Date Action Description DEC Staff
8/13/1998 Site Characterization Workplan Approved Phase II site assessment work plan. Sally Schlichting
10/4/1999 Site Ranked Using the AHRM By ADEC staff. Bill Janes
10/5/1999 Voluntary Cleanup Program VCP application approved. Bill Janes
10/8/1999 Site Added to Database BTEX, GRO, and DRO contamination. Bill Janes
6/25/2001 Update or Other Action 1500 cubic yards of material excavated last week and stockpiled on Whitestone property near airport. Jason Ginter will keep me posted on final disposal or treatment options. Says further excavation is problematic due to spread of contamination at water table. GW does not appear to be contaminated though. Bill Janes
1/8/2002 Update or Other Action Project tickler update - email sent to Jason Ginter at Smith Bayliss asking for status report. His reply is in my Outlook site file for this date. Thick report expected soon! Bill Janes
3/8/2002 Update or Other Action Project tickler update - A report is supposedly ready. Second email sent to Ginter. Bill Janes
6/7/2002 Update or Other Action Reviewed 4/24/02 Corrective Action Final Report. Not approved. Sent an email to Ginter at SBL. No GW sampling conducted and it appears this should occur. Email this date stored in site file Jnu-Fbks Outlook public folder, SE C Sites. Bill Janes
10/31/2006 Update or Other Action Email from Jason Ginter at Smith Bayliss. Whitestone interested in sampling the 1,500 cy stockpile to see if it meets cleanup levels at this time. The site remains vacant. GW ranges from 14 to 19 feet bgs. The wells that Whitestone installed never produced any water as they were too shallow. Bill Janes
5/11/2007 Update or Other Action Ledger Code requested for project manager change to Wanstall. Sampling of contaminated soil stockpile was discussed with consultant. Bicknell Construction has apparently bought the quarry property where the soil is stockpiled and is funding the sampling. Bruce Wanstall
1/18/2008 Update or Other Action Review database record and discuss workplan DQOs for the property in downtown Hoonah where the residual petroleum contamination smear zone is over 15 feet below ground surface. Groundwater at the site is intermittent making sampling for a contamination trend not feasible. Groundwater is unlikely potable due to the influence of marine and surface water. Bruce Wanstall
3/12/2008 Exposure Tracking Model Ranking Contamination cleanup at the former bulk fuel tank farm property was evaluated using the environmental tracking module. A conceptual site model for the contaminated site property is needed to address undetermined exposure risk for the ground water ingestion and vapor intrusion pathways. Bruce Wanstall
5/24/2011 Potentially Responsible Party/State Interest Letter DEC has sent a Soil and Groundwater Site Assessment Work Plan Request letter by regular mail to Mr. Keith Walker owner of Whitestone Logging concerning historical petroleum contamination from the bulk fuel tank farm formerly located on USS 2571 Tract #1 in Hoonah. The letter provides Alaska Statutes establishing cost recovery procedures and notification of State Interest in seeking recovery from responsible parties, expenditures associated with State oversight of the cleanup process and/or assumption of the lead role in the investigation and cleanup efforts to seek a permanent and timely cleanup remedy in accordance with Alaska Administrative Code Title 18 Chapter 75.325. Bruce Wanstall
11/7/2013 Exposure Tracking Model Ranking A new updated ranking with ETM has been completed for source area 73669 bulk fuel tank farm. Bruce Wanstall
12/23/2014 Institutional Control Record Established Institutional Controls established and entered into the database. As landowner and responsible party, Keith Walker (Whitestone Logging) agrees to the terms and conditions of the DEC Corrective Action Complete Determination, as stated in decision letter for the L Kane Tank Farm, dated December 23, 2014. Failure to comply with the terms and conditions of the determination may result in DEC reopening this site and requiring further remedial action in accordance with 18 AAC 18 AAC 75.380(d)(2). Bruce Wanstall
12/23/2014 Institutional Control Periodic Reporting Any future change in land use may impact the exposure assumptions cited in the cleanup complete decision document. If land use and/or ownership changes, the institutional control management conditions may not be protective and DEC may require additional remediation and revised conditions. Therefore the Whitestone Logging Company shall report to DEC every five years to document land use, or report as soon as Whitestone becomes aware of any change in land ownership and/or use, if earlier. The report can be sent to the local DEC office or electronically to DEC.ICUnit@alaska.gov. Bruce Wanstall
12/23/2014 Cleanup Complete Determination Issued Petroleum contamination remains on-site in soil above approved cleanup levels in a subsurface layer saturated with water. Removal of the contamination below the 15 foot depth via excavation is technically unfeasible. Nevertheless, DRO and GRO levels exceed human health exposure limits in this deep layer of soil and shall be documented and maintained to limit exposure to these concentrations. Attempts to characterize groundwater contamination in this subsurface lens found insufficient supply of water to collect samples. Based on information currently available, DEC finds that groundwater at the site lacks sufficient productivity to be source of drinking water or to transmit contamination to surface water. DEC concludes, in concurrence with recommendations in the environmental consultant’s final report, that there is no unacceptable risk to human health or the environment as long as the contamination is properly managed. A Notice of Environmental Contamination (deed notice) is recorded in the State Recorder’ Office as an institutional control (IC) that identifies the nature and extent of contamination at the property and the conditions that the owners and operators are subject to in accordance with this decision. This determination is in accordance with 18 AAC 75.380(d)(2) and does not preclude DEC from requiring additional assessment and/or cleanup action if future information indicates that this site may pose an unacceptable risk to human health or the environment. Bruce Wanstall
12/24/2014 Institutional Control Compliance Review IC compliance review conducted and staff changed from Bruce Wanstall to IC Unit. The IC Unit will have the deed notice recorded. Expecting the signed agreement page to be returned within 30 days of Closure Letter. Reminder system set to follow-up on land use conditions with the responsible party in five years. Kristin Thompson
1/9/2015 Institutional Control Update Signed agreement to the terms and conditions of the 2014 Corrective Action Complete Determination with institutional controls received from the responsible party. Kristin Thompson
9/11/2020 Institutional Control Compliance Review IC review conducted on this date and sent to the RP on record. 5 year review period to document land use. Next IC compliance review due in 2025. Cascade Galasso-Irish

Contaminant Information

Requirements

Description Details
Restricted to Industrial / Commercial Land Use Any future change in land use may impact the exposure assumptions cited in the cleanup complete decision document. If land use and/or ownership changes, the institutional control management conditions may not be protective and DEC may require additional remediation and revised conditions. Therefore the Whitestone Logging Company shall report to DEC every five years to document land use, or report as soon as Whitestone becomes aware of any change in land ownership and/or use, if earlier. The report can be sent to the local DEC office or electronically to DEC.ICUnit@alaska.gov.
Excavation / Soil Movement Restrictions Soil contamination is located in a thin layer of contaminated clay at depths of 16 feet and greater and intermittently saturated with water influenced by tidal waters from Port Frederick in Hoonah. The contamination is located more than fifty feet from any occupied structure, as indicated in Attachments C: Site Figure and Attachment D: Plat Map in the Cleanup Complete wICs decision letter. Any proposal to excavate soil in the area of identified contamination must receive approval from the DEC and a work plan describing how the soil will be tested and how it will be managed for remediation must be submitted for review and approval prior to excavation.
Groundwater Use Restrictions Installation of groundwater wells requires coordinated with DEC for approval before any proposed work begins.
Advance approval required to transport soil or groundwater off-site. Standard condition.
Movement or use of contaminated material (including on site) in a manner that results in a violation of the water quality standards is prohibited (18 AAC 70) Standard condition.
