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
Crude oil contamination. Contaminated soils were discovered under and above the liner during liner replacement operations in 1992. Oil appears to have penetrated into subsurface soil between the containment area's concrete side slope and the catalytically blown asphalt liner. Soil was excavated both above and below the liner to maximum extent practical, considering stability of the containment dike's slope. Bioventing and monitoring is conducted and reported under the East Tank Farm record (1200.38.017). Initial reports simply estimated the release to have involved "more than 50 gallons," but onsite personnel indicate there may have been multiple (or a massive) release(s). Free product continued to be collected from recovery well T14-MW2 through 2012.
Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 3/25/1993 | Update or Other Action | Receipt of Tank 14 - East Tank Farm Site Assessment Report dated November 1992. Results also reported with Nov 1993 report. 23 soil samples and one water sample analyzed for EPH (diesel), VPH (gas), TRPH, and BTEX compounds. In soil, only EPH above the project target cleanup level (200 mg/kg) and current 2009 Table B Method 2 cleanup for DRO (230 mg/kg) at up to 780 mg/kg. Water sample results were 273 mg/L EPH and 880 mg/L TRPH , the other analyses were invalidated due to lab contamination. This water sample was collected from borehole T14-11. | Keather McLoone |
| 5/14/1993 | Site Added to Database | Crude oil contamination. | Former Staff |
| 6/1/1993 | Update or Other Action | June 1993 Workplan Tank 13/14 Dike Investigation. | Keather McLoone |
| 11/1/1993 | Update or Other Action | Report entitled Tank 13/14 Dike Investigation Valdez Marine Terminal - Spill Report Number 1992247 dated November 1993. Results from both the 1992 and 1993 work were up to 19,200 mg/kg TRPH and 780 mg/kg EPH but extent of contamination is estimated to be extremely limited in extent in thin discontinous layer over the top of bedrock and under liner. | Keather McLoone |
| 1/6/1995 | Site Number Identifier Changed | Region changed from 40 to 71. Old Reckey was 1992400125401. | Scott Rose |
| 4/21/1998 | Site Ranked Using the AHRM | Ranking action added now because it was not added when the site was originally ranked. | Bill Petrik |
| 12/5/2000 | Site Ranked Using the AHRM | Changed Population Density Value from 0 to 5. | Former Staff |
| 12/28/2007 | Exposure Tracking Model Ranking | Initial ranking with ETM completed. | Pam Clemens |
| 8/25/2008 | Update or Other Action | Status update by phone from SLR that the plan is still to reinstall recovery well (T14-MW3) pump as it would appear to be designed to address this source area. Observations made in 2007 showed oil droplets in the well. | Keather McLoone |
| 12/17/2012 | Site Characterization Report Approved | Reporting for this site is done under the East Tank Farm's "informational" file (1200.38.017). Monitoring wells T14-MW1, T14-MW2, and T14-MW3 continued to have free-phase product present. Thus, water quality samples were not collected. T14-MW2 continues to be used as a recovery well, using a pump and treat strategy. 11,533 gallons of hydrocarbon-impacted GW was recovered from T14-MW2 in 2012. | Richard Bernhardt |
| 4/24/2013 | Update or Other Action | Coordinates updated by comparing the 2012 work report to Google Earth Imagery. | Richard Bernhardt |
