Problems/Comments
Two 515 gallon USTs one gasoline and one diesel were removed from one excavation in 1989, contaminated soil was used as backfill. In 1993, 10 soil borings did not detect TPH above 2,000 mg/kg. Groundwater was impacted, 4 monitoring wells were installed. Samples detected DRO up to 3.31 mg/L in one well; the remaining wells were below table C cleanup levels. A 2004 geoprobe investigation delineated the area. Soil was impacted in a thin zone 4-9' bgs in an area covering approximately 10 x 20 feet. Monitoring wells were inspected in 2007 and were no longer serviceable. Five new wells were installed in 2011 and sampled for DRO and BTEX. DRO was detected in soil borings and groundwater samples but all samples were below the most stringent cleanup levels. The ETM ranking was updated based on site conditions described in the 2011 Site Cleanup Investigation and all pathways were either incomplete or deminimus exposure.
Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 10/20/1989 | Update or Other Action | REM; Federal Avaiation Administration removed two USTs, one gasoline and one diesel. Three analytical soil samples were collected and analyzed, and indicated up to 80,000 ppm TPH. Excavation was backfilled with original soil before analytical results were received. Tanks disposed of at Nenana landfill. | Former Staff |

| 12/4/1989 | Site Added to Database | Former Staff | |
| 12/5/1989 | Leaking Underground Storage Tank Cleanup Initiated - Petroleum | LCAU; Removal of a gasoline and a heating oil tank. Soil contamination remains on-site. : LCAU date changed DB conversion | Former Staff |
| 2/23/1993 | Update or Other Action | RPL2; Peterson sent PRP-CS Database Notification Letter to RP requesting update and more environmental information concerning the contaminated site. RP responded with corrections on ADEC site report. | Former Staff |
| 10/15/1993 | Site Characterization Report Approved | HLA prepared Release Investigation Report for Julius H-Marker facility. Drilled 4 monitoring wells, and sampled soil from the borings. Soil contained up to 1900mg/kg TPH and groundwater contained 2.24mg/L TPH. BTEX was below cleanup levels. | Kim DeRuyter |
| 6/6/1994 | Update or Other Action | CORR; Wingerter sent letter informing RP of their financial liability under new ADEC cost recovery policy. State is authorized, under Section 9003(h) of the Resource Conservation and Recovery Act to take action on this LUST facility. | Former Staff |
| 5/25/2000 | Update or Other Action | Eileen Olson sent file review letter at FAA staff request. FAA wanted to know the site status. Additional characterization is required. | Mitzi Read |
| 1/10/2005 | Document, Report, or Work plan Review - other | US Army Core of engineers prepared an Environmental Restoration Investigation for the Julius H-Marker Facility. Samples collected from soil borings were analyzed for GRO, DRO, RRO and BTEX. DRO was detected to 1080mg/kg. Groundwater samples were collected and analyzed for GRO, DRO, RRO, and BTEX. DRO was detected at 3.31mg/L. | Kim DeRuyter |
| 12/13/2007 | Document, Report, or Work plan Review - other | Reviewed November 9, 2007 draft wrokplan for 4 FAA Nenana sites. The Julius H- Marker GW monitoring wells installed previously will be decommissioned and replaced. 2004 groundwater samples contained DRO up to 3.31 mg/L. | Kim DeRuyter |
| 1/10/2008 | Exposure Tracking Model Ranking | Future exposure to groundwater, low potential exposure to ecological receptors, and deminimis exposure to subsurface soil were the complete pathways at the site. RP proposes monitored natural attenuation. | Kim DeRuyter |
| 3/2/2009 | Update or Other Action | Reviewed and approved the Final Site Characterization Work Plan received 2/26/09. | Kim DeRuyter |
| 12/30/2011 | Document, Report, or Work plan Review - other | The Site Cleanup and investigation (SCI) report dated December 14, 2011 describes the installation of 5 new monitoring wells at the Julius H-Marker. | Kim DeRuyter |
| 12/30/2011 | Cleanup Complete Determination Issued | The site was ranked based on the current site conditions described in the 2011 Site Cleanup and Investigation report. All pathways were either incomplete or deminimis exposure. Soil and groundwater concentrations were all below the most stringent cleanup levels with the exception of soil from one boring that detected 352 mg/kg DRO. This sample contained chips of preserved wood and a review of the chromatographs indicated that the contaiminant was creosote. This site has been determined to be protective of human health, welfare, and the environment and a cleanup complete letter was issued on May 31,2012. | Kim DeRuyter |
| 8/27/2018 | Document, Report, or Work plan Review - other | Remedial Investigation WP reviewed and DEC comments provided. Objectives include: • Advance soil borings and collect surface and subsurface soil samples to delineate the presence and extent of contamination in soil adjacent to the Former Fuel Storage and Pipeline Facility. • Install test pits to assess landfill contents and collect analytical soil samples in the Former Landfill Site. • Decommission historical groundwater monitoring wells at the Former Julius H-Marker site. | Gretchen Caudill |
| 3/11/2019 | Update or Other Action | Monitoring wells decommissioned during the 2018 SI | Gretchen Caudill |
