Problems/Comments

On 9/6/2007, the owner of a residential rental property removed heating fuel from an aboveground home heating oil tank, placed it in trash cans, and did not cover the cans with lids. Rain water displaced the fuel and it was released to the ground. 7/31/18: An excavation has occurred and one cubic yard of petroleum contaminated soil has been taken to Bicknell Inc. for treatment. The site meets ADEC cleanup levels.

1/21/2011 Update or Other Action DEC addressed a professional inquiry (property investor Phase I Study) into any potential impacts to neighboring properties that may occur as a result of the oil spill. The responsible party was non-responsive when the site was transfer from the SPAR emergency response team to the CS Program in fall 2008. Using evidence of the spill event and personal knowledge of the area, a risk evaluation was prepared for the inquiry. Bruce Wanstall

5/12/2014 Institutional Control Record Established The ownership of the property is currently unclear; issued the following NEC: NOTICE OF ENVIRONMENTAL CONTAMINATION As required by the Alaska Department of Environmental Conservation (ADEC), Grantor, pursuant to 18 AAC 75.375 b (3), Darlene Hoover, Grantee, as the owner [and operator] of the subject property, hereby provides public notice that the property located at: 475 B 7th Avenue, Skagway, AK 99840 has been subject to a discharge or release, regulated under 18 AAC 75, Article 3, as revised April 8, 2012. On September 10, 2007, a pollution incident at 475 B 7th Avenue, Skagway, AK, was reported to the ADEC by the Skagway fire chief. Reportedly, heating oil was removed from a tank and stored in trash barrels and left exposed to the rain. Rain displaced approximately 80 gallons of heating fuel and may have impacted neighboring properties. Numerous attempts were made to contact the property owner and engage him in cleanup efforts at that time, however, no further characterization or cleanup was completed according to ADEC records. Due to the incomplete characterization and cleanup work at this site as required under 18 AAC 75, exposure risks to human health and the environment are determined to be present. Danielle Duncan

5/11/2015 Update or Other Action Last week I spoke with a gentlemen at Rescon who was going to do the Hoovers a personal favor and do some geo-drilling on site, however, I told him that geo-drilling was probably too expensive for the size and scope of this cleanup. What we need is some test pits in the known location(s) of the spill and an excavation using PID readings to guide it. Talked to D. Hoover today and she will call a consultant and get a work plan for test pits etc. Danielle Duncan
8/5/2015 Update or Other Action Requested work plan via certified letter this date. Certified letter was received by RP on 8/12/15. Danielle Duncan
10/1/2015 Update or Other Action Requested a work plan within 30 days this date. Certified letter # 7014 0150 1161 6838 Danielle Duncan
11/3/2016 Update or Other Action Requested a work plan within 30 days this date. Certified letter # 7014 2120 0001 1008 Danielle Duncan
10/31/2017 Document, Report, or Work plan Review - other Approved a report of 7 soil borings in the area of the petroleum release at 1-2 feet (ft.) below ground surface (bgs). Soil from the base of each boring was field screened using a photoionization detector (PID). Two analytical samples and a duplicate were collected and analyzed; both of the samples had DRO above the ADEC cleanup level of 250 mg/kg. Sample CZ-01 had a concentration of 8,300 mg/kg and CZ-06 had a concentration of 530 mg/kg. These results indicate that there is contamination above ADEC cleanup levels and that the contamination may have migrated onto the neighbor’s property. Danielle Duncan
11/13/2017 Update or Other Action Nortech is working on a cleanup plan. Danielle Duncan
12/4/2017 Update or Other Action Per the consultant: NORTECH has met our current scope of work and has not received approval to extend that scope of work to include writing a new work plan or conducting additional work at the Site. However, the responsible party is currently traveling internationally and communication with him is not consistent. As we have not received permission to extend our scope of work, NORTECH will not be able to meet the January 1, 2018 deadline that the ADEC set down for the new work plan. NORTECH does not currently have a timeline for writing a work plan as Mr. Hoover’s availability to respond to emails while he is traveling is not known. NORTECH will update the ADEC once we hear back, and will work with the ADEC to create a timeline for submittal of a new work plan and completion of the work authorized under the new work plan.

12/22/2017 Update or Other Action RP is unable to get a work plan - will get one after the first of the year. Danielle Duncan

2/1/2018 Document, Report, or Work plan Review - other Approved a corrective action plan to excavate the contaminated soil. Danielle Duncan
6/18/2018 Update or Other Action I believe the excavation is complete - sent soil transport form 6/6/18. Danielle Duncan

8/1/2018 Site Characterization Report Approved Approved the Corrective Action Report this date. The report documents the results of an excavation of petroleum contaminated soil guided by a photoionization detector (PID). Nortech excavated approximately one cubic yard of petroleum contaminated soil to a depth of 2.8 feet (ft.) where groundwater was not encountered. The excavation surface area was 80 square ft. and the contamination did not extend off the property. The contaminated soil was taken to Bicknell Inc. for remediation. Six confirmation soil samples were collected from the base and sidewalls of the excavation. These were analyzed for DRO, gasoline range organics (GRO), and volatile organic compounds (VOCs). One sample with the highest PID reading was also analyzed for polycyclic aromatic hydrocarbons (PAHs). The results were below ADEC cleanup levels for all contaminants and the site will be evaluated for closure. Danielle Duncan
8/10/2018 Cleanup Complete Determination Issued Danielle Duncan
