Problems/Comments

In April, 2014 a cracked fitting was discovered on a fuel line between two aboveground heating oil tanks at 363 2nd Avenue in Skagway. An unknown amount of diesel fuel had been released to the surface at the time of discovery. The fuel line was subsequently repaired, and prior to initial remediation the aboveground storage tanks (ASTs) were removed. In October 2014 approximately 200-cubic yards of contaminated soil was removed from the site and transported to Seattle for disposal. Excavation activities were limited due to the building foundation and presence of the groundwater table. Sample analysis confirmed soil contamination remains above DEC cleanup levels and due to remaining contamination at the soil-groundwater interface, groundwater contamination may also be present but has not been evaluated. The upper floor of the building on the property is used for residential rental units and the lower floor is used as seasonal commercial space. October 2015: Soil contamination remaining in the sidewalls and base of the excavation is in the range of 200-740 mg/kg GRO and DRO contamination in the range of 3,300-7,700 mg/kg. Groundwater contamination is under investigation.

1/30/2015 Update or Other Action Introduced myself to RP and requested that monitoring wells be installed and a drinking water well search be conducted. RP plans on having the work done in May, but I expect a work plan well before then, and the ground will likely be thawed before then. Danielle Duncan
5/18/2015 Update or Other Action Was able to contact the RP (via email) and discussed the need for a work plan to install groundwater monitoring wells within 30 days of today's date. The soil contamination left in place is on the order of 33,000-77,000 mg/kg DRO and RRO which presents a significant vapor intrusion hazard. There is an apartment upstairs in the building and the lower floor is used as a store front. I also requested that a drinking water well search be conducted as part of the work. I was told that the site is hooked up to city water. Danielle Duncan
7/13/2015 Update or Other Action Found mathematical error in Golder Associates report "Test pitting and remedial excavation works completed at 363-2nd Avenue, Skagway, Alaska", dated December 22, 2014 and reported to Golder Associates. The issue was that the report author had taken dilution values from the laboratory report and applied them to the data when the laboratory had already done it. I am expecting a revised report soon. The petroleum values will be less than they currently are. Danielle Duncan
7/15/2015 Update or Other Action Rec'd corrected report from Golder Associates - the data values in general have decreased. Danielle Duncan
7/15/2015 Update or Other Action Sent a letter today requesting a work plan within 30 days of receipt to address contamination on the property. Soil contamination remaining in the sidewalls and base of the excavation is in the range of 200-740 mg/kg GRO and DRO contamination in the range of 3,300-7,700 mg/kg. The work plan will include: 1. The installation of groundwater monitoring well(s). 2. A drinking water well search to determine whether there are drinking water wells nearby that may become contaminated as a result of this spill. 3. A vapor intrusion hazard investigation. Danielle Duncan
8/3/2015 Update or Other Action Spoke to the RP and Golder Associates is preparing a work plan for review. The RP said that no fumes or odor are apparent at/inside the property. Danielle Duncan
8/20/2015 Update or Other Action Spoke to Golder - they are preparing a work plan to install monitoring wells and address the vapor intrusion hazard. The building is on a slab foundation. Danielle Duncan
8/28/2015 Document, Report, or Work plan Review - other Rec'd Golder's work plan "Additional Environmental Investigation at 363 2nd Avenue, Skagway, AK" this date. Danielle Duncan
9/4/2015 Site Characterization Workplan Approved Approved Golder's work plan "Additional Environmental Investigation at 363 2nd Avenue, Skagway, AK" this date. The work plan details the installation and sampling of 3 groundwater monitoring wells in order to determine whether groundwater contamination has occurred and if there is a substantial vapor intrusion risk. The City of Skagway has a Class A water system supplied by 3 groundwater wells and Golder is not aware of any private drinking water wells located down gradient of the site. Danielle Duncan

6/21/2018 Workplan Requested Due to the remaining contamination and the risk of vapor intrusion into the building which houses both a business and rental suites, and the observed groundwater contamination, the ADEC is requesting a work plan to delineate the extent of groundwater contamination and the potential for vapor intrusion. This is the ADEC’s third request. If no work plan is received by August 30, 2018, the ADEC may take additional actions including placing a deed Notice of Environmental Contamination on the property. Danielle Duncan
11/6/2018 Site Characterization Workplan Approved Approved the Alaska Fur Gallery Groundwater Monitoring and 2018 Work Plan this date. Further site characterization activities include soil sampling, groundwater sampling, and indoor air sampling. Danielle Duncan
