We make every effort to ensure the data presented here is accurate based on the best available information currently on file with DEC. It is therefore subject to change as new information becomes available. We recommend contacting the assigned project staff prior to making decisions based on this information.
Problems/Comments
Due to a line failure, up to 250 gallons of diesel were released from an aboveground heating oil tank into the crawlspace beneath the building. DEC requested the soil be removed from the site to reduce the risk of exposure to the fuel contamination. The facility manager responded by hand-removing approximately 10 tons of contaminated soil from the crawlspace to a depth of four feet below ground surface. The contaminated soil was transferred to a shipping container and was sent to Waste Management’s Arlington, Oregon disposal facility for remedial treatment.
Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 8/20/2007 | Spill Transferred from Prevention Preparedness and Response Program | Site transferred by PERP staff Scot Tiernan. Spill No. 07119917902; Spill Date 6/28/07; Substance = Diesel; Quantity = ~250 gallons; PERP File No. 1526.02.036. | Mitzi Read |
| 8/21/2007 | Site Added to Database | Site added to the database. | Mitzi Read |
| 8/27/2007 | Exposure Tracking Model Ranking | Initial ranking completed. | Mitzi Read |
| 11/21/2007 | Update or Other Action | DEC letter of State Interest request for site assessment was sent to G & C Inc relating to a heating oil spill that migrated into soil beneath structures on the property. | Bruce Wanstall |
| 1/23/2008 | Update or Other Action | Received Nortech Site Assessment Report; laboratory data are acceptable and are adequate to determine that 30-50 cubic yards of heavily contaminated material is present beneath the building in the crawlspace. Corrective action is recommended and suggestion are made to the responsible party. Assessment of the oil impacts to the building/property was conducted in July, 2007. | Bruce Wanstall |
| 1/29/2008 | Update or Other Action | Met with the PERP staff project manager to discuss the level of urgency that may be necessary to address the spill of several hundred gallons of heating oil into the building crawlspace; discuss with Jason at Nortech who was involved with response actions; a vapor barrier (plastic) is the site control used to limit vapor intrusion; the crawlspace is very shallow. | Bruce Wanstall |
| 3/24/2008 | Update or Other Action | ADEC letter was sent today requesting information within 60 days on the cleanup remedy and site controls taken on the property by the responsible party/owner/operator. Oil spill site conditions may warrant that ADEC take the lead conducting remedial action on the property. | Bruce Wanstall |
| 4/1/2008 | Update or Other Action | ADEC reviewed the status of the site cleanup and recent correspondence with the responsible party. Contact the apparent environmental consultant concerning additional action at the site. Copy of each of the ADEC data request letters mailed to ALS in November 2007 and March 2008 were forwarded to Nortech via email | Bruce Wanstall |
| 4/17/2008 | Update or Other Action | The responsible party contacted ADEC to discuss site cleanup workplan and contaminated soil disposal options. Certified letter return receipt was received by the ADEC 3/26/08. | Bruce Wanstall |
| 4/22/2008 | Update or Other Action | ADEC received a proposed contaminated soil disposal plan for review and comment. | Bruce Wanstall |
| 8/23/2010 | Update or Other Action | Evaluate the Site Assessment and contaminated soil removal workplan for status of the cleanup and off-site disposal; inquire with consultant Nortech on status of a Final Report and fate of the contaminated material. | Bruce Wanstall |
| 1/25/2012 | Final Cleanup Report Reviewed | DEC has approved the Final Cleanup Report by Nortech Environmental Engineering for the cleanup process conducted at the facility located on 290 2nd Ave in Skagway. Closure samples collected at the perimeter of the hand-excavated removal site in the crawlspace indicate that the cleanup was successful in capturing all accessible contaminated material. A minor quantity of contaminted material remains under the concrete foundation wall in concentration between Method Two migration to groundwater and ingestion soil cleanup levels. It was not feasible to remove this material without threatening the stability of the building. A cleanup complete determination is recommended. | Bruce Wanstall |
| 2/1/2012 | Exposure Tracking Model Ranking | An updated ranking with ETM has been finalized for source area 75437 Aboveground Diesel HOT. | Bruce Wanstall |
| 2/15/2012 | Cleanup Complete Determination Issued | The contaminated soil was transferred to a shipping container and was sent to Waste Management’s Arlington, OR disposal facility for remedial treatment. Based on the information provided to date, the DEC has determined that the contaminant concentrations remaining on site do not pose an unacceptable risk to human health or the environment, and this site will be closed. | Bruce Wanstall |
Contaminant Information
| Name | Level Description | Media | Comments |
|---|---|---|---|
| DRO | Between Method 2 Migration to Groundwater and Human Health/Ingestion/Inhalation | Soil | The concentrations of DRO in the confirmation soil samples collected from soil remaining at the site were 211 mg/kg, 204 mg/kg, 403 mg/kg and 2,380 mg/kg. The 2,380-mg/kg result was in soil collected at a depth of four feet. This soil, located under the concrete foundation wall, is a de minimis quantity, which could not be removed without threatening the stability of the building. |
