05/01/1989Preliminary Assessment ApprovedADOT contracted Shannon and Wilson, Inc. to investigate past uses and potential hazards at the site as part of a right-of-way road project. Shannon and Wilson, Inc. report, "Preliminary Hazardous Waste Site Evaluation, proposed Minnie Street Connector, Fairbanks, Alaska" indicates that no documented releases have occurred at this site, though a site visit revealed evidence of fuel spillage and releases from ASTs and fuel pumps.No Longer Assigned,
12/01/1990Site Characterization Report Approved(Old R:Base Action Code = SI - Site Investigation). DOT contracted Shannon and Wilson, Inc. to investigate site. Their report, "Final Report: Illinois Street and Minnie Street Connector Hazardous Waste Field Investigation, Phase II" dated 12/90 reports that 14 of 18 soil samples from monitoring wells exceeded 100 ppm TPH ranging from 21 - 120,000 ppm with the highest levels found at, or near the water table. All water samples had high levels of BTEX and a floating yellow product was observed in each of the 5 product monitoring wells ranging from 0.06' - 0.57'. 3 of 4 surface soil samples exceeded 100 ppm TPH and 1 sample contained 1.7 ppm PCE.No Longer Assigned,

Asks to submit questions and comments.Thomas, Cindy
12/28/1992Update or Other Action(Old R:Base Action Code = CORR - Correspondence (General)). (OSLP) ARRC submitted comments and preferred Site Assessment plan for Illinois-Minnie Site. This Project was first proposed in 1990.Thomas, Cindy
12/28/1992Update or Other Action(Old R:Base Action Code = CORR - Correspondence (General)). (OSLP) Correspondence returned to ARRC thanking for comments. Will incorporate into ADEC final version. Will keep ARRC and all parties updated on future actions.Thomas, Cindy
01/31/1995Update or Other ActionSITE SUMMARY: Ground water impact known, but cleanup delayed pending the outcome of MSLUG efforts. ADEC notified operator of draft COBC to guide cleanup in 1995.Thomas, Cindy
09/04/2001Update or Other ActionNortech Environmental and Engineering Consultants submit Phase II sampling results and draft remediation workplan. Documented soil contamination associated former ASTs and injection well. Jonathan Williams, EPA UIC Region 10, sent report. Soil contamination consists of petroleum hydrocarbons. Site may in or nearby area-wide groundwater contamination as documented in USGS Water Resources Investigation Report Number 96-4049 dated 1996.Bauer, Doug
10/03/2001Proposed PlanPlan to excavate contaminated vadose zone soil approved. Excavation to be directed by initial Phase II soil boring results and on-site trenching with soil gas screening and/or Hanby assays. Determination of the nature of onsite groundwater contamination and its relationship to area-wide groundwater contamination will be done concurrently with or after excavation.Bauer, Doug
04/11/2002Update or Other ActionPRP Cost Recovery letter and invitation to participate in Fairbanks Area-wide Industrial Reclamation (FAIR) project sent Suburban Corporate headquarters in New JerseyBauer, Doug
04/11/2002Update or Other ActionNortech requested an amendment to the approved cleanup workplan in a March 22, 2002 letter. Response sent stating that alternatives to the approved Method 2 standards requires a limited risk evaluation of additional pathways. Groundwater cleanup will probably be based on area-wide groundwater cleanup approach through FAIR.Bauer, Doug

12/01/2003Update or Other ActionHart Crowser submitted groundwater monitoring report for ARRC. Four wells on the Van Gas property, as well as six former MSLUG wells were sampled in conjunction with the FAIR project. Highest petroleum concentrations were observed in AR 12 (benzene at 44 ppb). PCE was found in AR-3 at 5.8 ppb.Wiegers, Janice
05/28/2004Update or Other ActionHartCrowser submitted groundwater monitoring report for ARRC. AR12 and AR15 not sampled due to presence of product on the water table. DRO was the only petroleum compound exceeding cleanup levels (2.2 mg/L in AR-9). PCE exceeded cleanup levels in AR3 (0.016 mg/L).Wiegers, Janice
11/12/2004Update or Other ActionHartCrowser submitted groundwater monitoring report for ARRC. AR-12 could not be found due to surface work at the site. AR3, AR9, and A15 were surveyed in May and elevations were compared to benchmarks on the adjacent Saupe's site. The highest level of petroleum contamination was found in AR-15 (DRO at 5.6 mg/L). Benzene and GRO were not detected above cleanup levels. All VOCs were all below cleanup levels, except PCE in AR3 (0.015 mg/L)Wiegers, Janice
05/17/2005Brownfield InventoryIdentification of a site as part of the DEC's Brownfield Inventory does not automatically qualify a site for any specific brownfield benefits, liability protection, or funding. Those determinations must be made in concert with a DEC project manager on a site-specific basis, with consideration of the site history, extent of contamination, ownership, and redevelopment plans or potential.Wiegers, Janice
06/01/2005Update or Other ActionHart Crowser submits groundwater monitoring report for ARRC. Product present in AR-12 and AR-15. AR-12 contained 0.31 ft of product, the largest amount since monitoring began in 2003. File review indicates AR-12 is located near a former Van Gas dispensing area. A product sample was collected but results are not yet available. PCE exceeded cleanup levels in AR-3 (8.9 ug/L).Wiegers, Janice
06/29/2005Update or Other ActionARRC sends letter to Suburban Propane requesting that a plan be submitted to ADEC to address the product observed on site.Wiegers, Janice
07/05/2005Update or Other ActionTelephone call form Peter Beardsley with Nortech. Peter indicated AR-12 was screened at a depth of about 40 ft (observed through a down-hole camera).Wiegers, Janice
07/05/2005Update or Other ActionTelephone call from Peter Beardsley with NORTECH concerning free product at site. Referred him to Janice Wiegers and reports concerning fluctuating water table.Bauer, Doug
12/28/2005Update or Other ActionReceived September 2005 Groundwater Monitoring Report. According to the report, AR-3 and AR-9 were destroyed because of re-grading activities on the site. Floating free-phase product was observed in AR-12 so no sample was collected. One groundwater sample was collected from AR-15 and it had results of 46.7 mg/L DRO and 1.53 ug/L of benzene.Williams, Deborah
08/29/2006Update or Other ActionADEC received the April 2006 Groundwater Monitoring Well Installation and Groundwater Monitoring Report from Hart Crowser. According to the report, three new monitoring wells were installed on the property. AR-9A was installed downgradient of the former excavation area; AR-3A was installed in the northern corner of the property; and AR-9B was installed in the south east corner of the property (upgradient). Soil and groundwater results were non-detect for AR-3A and AR-9A, but AR-9B had DRO levels up to 13,300 ppm and GRO levels up to 512 ppm in the soil and DRO levels up to 18.2 ppm and benzene levels up to 15.5 ppb in the groundwater. AR-12 and AR-15 were not sampled because they both contained free-phased floating hydrocarbons. Williams, Deborah
05/15/2007Update or Other ActionADEC received the March 2007 Groundwater Monitoring Report for the Van Gas site. HartCrowser determined that the groundwater flow direction was in the west-northwest direction. Free-phase hydrocarbons were measured in AR-12 and AR-15 at a thickness of 0.01 foot. GRO, DRO, RRO and BTEX was non-detect in AR-3A and AR-9A. AR-9B had GRO levels up to 2.09 mg/L, DRO levels up to 8.63 mg/L and benzene at 0.026 mg/L. Williams, Deborah

01/26/2009Update or Other ActionADEC received from the Alaska RailRoad the September 2008 Groundwater Monitoring Event Reportfor the Fairbanks Area-Wide Industrial Reclamation Project. Report indicates that DRO is present above cleanup levels in monitoring wells AR-12 and AR-15. Benzene is also above cleanup levels in AR-12. Free product was measured (0.29ft) in well AR-9B. Groundwater flow direction as estimated to be to the southwest. Cardona-Marek, Tamara
