Peterson, Jeff
10/12/1994	Update or Other Action	(Old R:Base Action Code = RAPR - Remedial Action Plan Review (CS)). Reviewed and approved conceptual CAP by Gilfilian. CAP included baseline assessment of conditions, and using two computer models to evaluate site data (ARMOS 5.1) and develop Corrective Action system (SpillCAD 3.2). Gilfilian will provide information from each 6 tasks as data are available. ADEC asks that a demonstration be given for each model this winter.	Thomas, Ben
01/18/1995	Update or Other Action	SITE SUMMARY: Extensive ground water impact from the bulk tank farm and possible other sources (RR spur, FAI hydrant system, historic spills). Extensive GW assessment complete by D&M. Gilfilian is proposing using two computer models for fate and transport and treatment selection. Get both programs before approval. Treatment system design planned for spring 1995. Should include Free Product Recovery. Plume moves off site under road onto airport apron.	Thomas, Cindy
08/13/2001	Update or Other Action	Site Characterization Report submitted by Gilfilian. Report summarizes past work at site. Kent & Sullivan is new consultant working on site.	Wiegers, Janice
04/24/2002	Update or Other Action	Pilot Test and Feasibility Study Report reviewed. Air sparging system planned at downgradient plume edge to prevent further off-site migration. Additional data gaps to be filled with regards to corrective action feasibility.	Wiegers, Janice
07/10/2002	GIS Position Updated	Changed the Latitude, Longitude, Method Accuracy, Accuracy and Unit fields.	Goldman, Heather
10/22/2002	Cost Recovery Referral	Cost Recovery referral sent to DOL.	Wiegers, Janice
04/12/2004	Update or Other Action	2003 investigation report submitted. Samples were collected in June and October. EDB and EDC were not detected but further sampling for these compounds will be conducted in the railroad header area. The monitoring wells have frost-jacked and need to be resurveyed. Dissolved concentrations appeared to be lower near the air sparging system, which may indicate some treatment is occurring in this area. The air sparging system was operated three times during the summer. Some soil gas migration into adjacent wells was observed during system operation but the consultant indicated the threat of human exposure was minimal.	Wiegers, Janice
05/17/2005	Brownfield Inventory	Identification 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
08/23/2005	GIS Position Updated	Using a Site Plan from a Corrective Action Work Plan for 2001 Fairbanks Airport Bulk Plant, from Gilfilian Engineering, dated November 8, 2000, in conjunction with TopoZone Pro, entered the coordinates for this site. Metadata includes No Topo Basemap, TopoZone Pro Street Map, Black and White Aerial Photo, on a Medium Size Map, View Scale 1:10,000, Coordinate Datum NAD83. High degree of confidence in accuracy of location.	Hughey, Alyce
09/16/2005	Update or Other Action	2004 Monitoring report reviews result of water level measurements, groundwater monitoring, and details air sparing system operation. LNAPL was present in 2 wells where it had not been observed in the past. The report speculates that the unusually low water table may have been a factor. Two wells near the air sparge system show significant decreases in hydrocarbon concentration. The data supports the thesis that the air sparge system has been effective in containing downgradient migration of the plume. The lead scavanger EDC was detected in monitoring wells at the southern most corner of the plume. The lateral migration of this contaminant has not be delineated.	DeRuyter, Kim
04/10/2006	Update or Other Action	2005 Groundwater monitoring report received. EDC was observed in several wells located in both the source area and the downgradient edge of the plume. Benzene concentrations are decreasing in all wells except those in the central plume area where free product still exists. All sentinal wells remain non-detect for benzene. The air sparge system appears to have been sucessfull in limiting benzene migration.	DeRuyter, Kim
05/23/2006	Meeting or Teleconference Held	Met with Peter Ribbens and Shawn on site yesterday to discuss modifications to the 2006 monitoring plan. Peter has agreed to include spring and fall sampling at some of the downgradient wells in an attempt to further delineate the EDB and EDC contamination.	DeRuyter, Kim
09/05/2006	Update or Other Action	Received an e-mail from Peter Ribbens stating that Clay Sullivan, the Environmental Consultant for the site had reviewed the preliminary FIA dewatering information, and did not believe that the dewatering would impact the Tesoro groundwater plume. A copy of the e-mail was placed in the site file.	DeRuyter, Kim
12/05/2006	Site Characterization Workplan Approved	EDC in Downgradient Wells letter report received. Further investigation of the extent of EDC migration at the site has confirmed that EDC has migrated beyond the SVE system at the site. EDC has been detected below the Drinking water MCL in one well on the western property boundary. The letter report proposes: the installation of two more monitoring wells to close data gaps,year around operation of part or all of the SVE system, source investigation which will include additional monitoring wells, and a focused feasibility study. A complete report is pending. ADEC approves this interm action.	DeRuyter, Kim
05/31/2007	Update or Other Action	ADEC reviewed the 2006 Monitoring Report for the Tesoro Fairbanks Terminal site. According to the report, samples were collected from the wells in both June and October. The air sparging system was run between those dates and the results indicate a substantial decrease in the benzene levels from June to October. The downgradient sentinel wells did not contain detectable BTEX during either sampling event. EDC was detected in wells MW-31, MW-35, MW-38 and MW-42 which are downgradient of the air-sparge line. The 2007 sampling will include sampling to investigate the sources of EDC at the site. Depending on the 2007 data, Tesoro may change running the AS system from continuous to intermittent operation through October 2007 when the system will again be run continuously through the winter months to minimize line freeze up.	Williams, Deborah
06/01/2007	Institutional Control Record Established	An IC is established for a water well survey to be conducted at this site every third year because of the development in the area. The next water well survey will be due in 2008.	Williams, Deborah
03/13/2008	Exposure Tracking Model Ranking	Initial ranking with ETM completed.	Everson, Neal
06/04/2008	Site Characterization Workplan Approved	Reviewed 2007 investigation report and approved 2008 work plan. Semi-annual MW sampling events, delineate EDC plume, sample Caito's dww, and add Air Sparge wells.	Everson, Neal
07/06/2009	Report or Workplan Review - Other	Reviewed 2008 GWM Report. DEC concurs with recommendations and requested information on access to install MWs on off-site properties, requested well survey to the west and requested gw investigation at Tesoro hydrant fuel line site (100.38.171).	Everson, Neal
09/14/2009	Update or Other Action	Project manager changed to Tamara Cardona-Marek.	Wiegers, Janice
11/19/2009	Meeting or Teleconference Held	DEC staff met with RP and consultant to discuss actions done on site in 2009. EDC plume has been delineated using hydropunch samples. Residential drinking water well was sampled and there was detectable EDC. Tesoro is looking at potentially making the residential well deeper or moving it's location. Soil vapor probes were installed adjacent to the residence. No work plan was submitted for most of the work performed in 2009. The 2007 report contained a partial work plan for the plume delineation activities performed at the site.	Cardona-Marek, Tamara
