Problems/Comments
In September 1993, certified underground storage tank worker John Bertholl with Petroleum Services Inc. (PSI) removed a 500-gallon used-oil, underground storage tank (UST) from the Alaska Airlines Cargo Building at the Juneau International Airport. Concurrent with the UST removal, Smith Bayliss LeResche Inc (SBL) conducted an assessment of the site. Once petroleum contamination was identified in the excavated soil to remove the UST, SBL began a release investigation and identified a volume of fifteen cubic yards by field screening. DEC authorized PSI to transport the soil to Channel Sanitation where it was thermally remediated. In January 1994, SBL submitted the Release Investigation Report to the DEC which cited piping connectors as the source of the release. The tank had no sign of faulty material and was cleaned and then scrapped off-site in accordance with UST regulations. Two existing, active USTs used to store diesel and gasoline were situated on either side of the waste oil tank, prohibiting the complete removal of contaminated soil. Due to sloughing walls and the close proximity of other UST systems, the excavation was lined and then backfilled with clean material before the limits of subsurface contamination were found. Field screening and observation of the contaminated material indicated that soil contaminated with waste oil was fully removed and that the remaining contaminated soil was impacted by a release from one of the other UST systems. No groundwater was encountered in the excavation and therefore was not investigated for contamination.
Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 10/1/1992 | Update or Other Action | NOR; Leaking underground pipe connection and infrequent overfills over a 15-year period. | Former Staff |
| 1/27/1994 | Release Investigation | RELR; 500gallon used oil UST removed. Leaky pipe connection was discovered upon decommissioning. Other source of contamination: approximately 3 overfills in 15 years. 15cy oily soil were excavated and incinerated per DEC approval. Currently the UST pit is sealed pending a cleanup plan for the underground contamination. | Former Staff |

| 10/2/2001 | Update or Other Action | Changed Project Manager from Paul Horwath to Bill Janes. | Cynthia Pring-Ham |
| 12/12/2001 | Update or Other Action | Project manager changed from Janes to Wanstall. | Bill Janes |
| 1/14/2002 | Underground Storage Tank Site Characterization or Assessment | Supplelmental Release Investigation recieved investigating UST releases at the site. Groundwater moving downgradient to the southwest past the UST footprints: MW 02 had 73ppm GRO and 4.4ppm benzene, MW04 had GRO of 49ppm and benzene at 0.071, MW08 had 33ppm GRO and 2.3ppm benzene, MW07 had 22ppm GRO and 1.7ppm benzene, MW09 had 17ppm GRO and 1.7ppm benzene. | Bruce Wanstall |
| 7/5/2002 | Update or Other Action | Additional UST release investigation and remediation progress for this facility will be logged on database UST Event ID 2677. Unregulated heating oil tank removals at the adjacent Wings Air Cargo Building are managed as a site on the CS Database. | Bruce Wanstall |
| 7/26/2004 | Update or Other Action | Results of the June groundwater monitoring event were received for review. Concentrations of dissolved GRO in groundwater exceed cleanup level in 3 wells; concentrations of benzene exceed cleanup level in 5 wells; elevated dissoved oxygen compared with previous sampling events is attributed to ozone sparging unit remedial operation. | Bruce Wanstall |
| 10/12/2007 | Exposure Tracking Model Ranking | Environmental status evaluated using the environmental tracking module for the waste oil tank site assessment. Release Investigation data and the Corrective Action Remedy controls are used in this initial review. | Bruce Wanstall |
| 12/2/2009 | Document, Report, or Work plan Review - other | DEC approves the URS 2009 Ground Water Monitoring Report data and recommends continuing active treatment of a residual subsurface gasoline contaminated ground water and annual monitoring well sampling in the summer season. BTEX concentrations in ground water have declined but GRO and DRO concentrations in ground water still exceed Table C cleanup levels. | Bruce Wanstall |
| 12/29/2010 | Exposure Tracking Model Ranking | A new updated ranking with ETM has been completed for source area 77880 underground waste oil tank. | Bruce Wanstall |
| 11/25/2011 | Exposure Tracking Model Ranking | A new updated ranking with ETM has been completed for source area 77880 underground waste oil tank. The soil contaminated by the waste oil UST has been transported to the local treatment facility and thermally treated. Any remaining contamination in subsurface soil above MTG levels was released from another UST at the site and is managed under hazard ID 22996. | Bruce Wanstall |
| 12/13/2011 | Cleanup Complete Determination Issued | The DEC has concluded that a UST closure by removal release investigation and cleanup in 1994 at the Alaska Airlines Cargo Facility in Juneau satisfies 18 AAC 78 regulations allowing closure of the record on the contaminated sites database. Although the records for this Hazard ID 24525 and file 1513.26.014 will be Corrective Action Complete, the records for Hazard ID 22996 and file 1513.26.054 remain active to manage on-going soil and groundwater contamination stemming from the 1998 closure by removal of gasoline and diesel USTs at the Cargo Facility in Juneau. | Bruce Wanstall |
| 10/31/2014 | Exposure Tracking Model Ranking | A new updated ranking with ETM has been completed for source area 77880 underground waste oil tank. | Bruce Wanstall |
Contaminant Information
| Name | Level Description | Media | Comments |
|---|---|---|---|
| GRO | Between Method 2 Migration to Groundwater and Human Health/Ingestion/Inhalation | Soil | Of the samples taken from soils which remained underground following the release investigation, contaminants at only one sampling location (Sample B) exceeded DEC soil cleanup levels for the site. That location is below the center of the former used oil UST at a depth of 8.5 feet below the surface. In Sample B and its duplicate, the maximum concentration in soil for GRO was 610 mg/kg, |
| BTEX | Between Method 2 Migration to Groundwater and Human Health/Ingestion/Inhalation | Soil | Of the samples taken from soils which remained underground following the release investigation, contaminants at only one sampling location (Sample B) exceeded DEC soil cleanup levels for the site. That location is below the center of the former used oil UST at a depth of 8.5 feet below the surface. In Sample B and its duplicate the maximum concentration of benzene was 1.1 mg/kg, for ethylbenzene was 11 mg/kg, for toluene was 22 mg/kg and for total xylenes was 74 mg/kg. All other VOCs detected were below instrument detection in the 1994 laboratory analysis. |
