5/21/2008 Institutional Control Record Established Recommendations established and provided to tenants on a Fact Sheet. Tamara Cardona-Marek
6/24/2008 Update or Other Action ADEC received the Work Plan for Additional Site Assessment. Work Plan includes installation of 4 vapor probes to sample soil gas near buildings. ADEC recommends the addition of 4 vapor probes to the plan (2 per building) and the analysis of additional volatile petroleum components from the vapor samples collected. Tamara Cardona-Marek
7/11/2008 Leaking Underground Storage Tank Corrective Action Underway Met with Dan Carrier (Chevron) and Greg Montgomery (Arcadis) to discuss current activities at the site and plans to do additional assessment. ADEC recommended doing vapor probes on two sides of the buildings on site to assess the potential for vapor intrusion. Additional plume delineation to the west was discussed since the boundary of the plume has not been determined Tamara Cardona-Marek
8/29/2008 Update or Other Action Received and reviewed the First Semi-annual 2008 Groundwater Monitoring Report for Former Chevron, Texaco and Unocal bulk plants. Results are consistent with previous results. ARCADIS recommends eliminating PAH's analysis , EDB and VOC's. ADEC agrees but requires analysis for PCE/TCE. ADEC also agrees with wells TH-7, TH-17 and TH-18 to be sampled annually instead of semi-annually. Tamara Cardona-Marek
8/29/2008 Update or Other Action ARCADIS requests approval to transport waste soil resulting from installation of vapor probes. Transport approved although not necessary, all super-sack sample results were below cleanup levels. Tamara Cardona-Marek
12/18/2008 Update or Other Action ADEC received the Second Semi-annual 2008 Groundwater Monitoring Report for Former Chevron, Texaco and Unocal bulk plants. Results are consistent with previous monitoring events. Tamara Cardona-Marek
3/13/2009 Meeting or Teleconference Held ADEC discussed site with Arcadis and Chevron on 3/3/2009. ADEC requested that only one sampling event takes place this year and efforts are focused on developing graphs and plume maps that demonstrate contaminant reduction over time. MNA parameters should also be measured at the site during sampling events. Arcadis will do a Phase I assessment to determine if additional plume delineation to the west is needed. Tamara Cardona-Marek
1/22/2010 Report or Workplan Review - Other DEC reviewed the Annual 2009 Groundwater Monitoring and MNA Report. Contaminant concentrations seem consistent with previous monitoring events. Wells TH17, TH18 and TH13 could not be sampled due to access issues that need to be resolved with ARRC. Wells MW-25 and TH-2 could not be sampled due to the presence of LNAPL. Tamara Cardona-Marek
2/17/2010 Meeting or Teleconference Held DEC met with Chevron and Arcadis to discuss 2010 activities. Additional plume delineation to the West of the property will be performed. The completion of a risk assessment is being evaluated and a plan will be submitted in 2010. Tamara Cardona-Marek
5/26/2010 Update or Other Action DEC requested that Chevron sample for sulfolane one well within the source area to determine if sulfolane may be a COC. Tamara Cardona-Marek
7/22/2011 Cleanup Plan Approved DEC reviewed and approved the Work Plan for Surfactant Enhanced LNAPL Recovery Pilot Study submitted by Arcadis. Tamara Cardona-Marek
6/19/2012 Report or Workplan Review - Other DEC received and reviewed the 2012 Groundwater Monitoring Workplan from Arcadis. Tamara Cardona-Marek
8/28/2012 Meeting or Teleconference Held DEC met with Chevron and Arcadis to discuss actions for 2012-2013. It was discussed how to establish a "baseline" of the contamination . DEC suggested an in depth file review with a document that summarizes the current sttaus of the site and how it will be moved forward. A "Record of Decision" was discussed as an alternative to document the current status and the actions already completed. Tamara Cardona-Marek
4/29/2013 Meeting or Teleconference Held DEC met with Chevron and Arcadis to discuss the current status of the site and upcoming activities. Arcadis performed groundwater monitoring in 2012; results were consistent with previous events and contamination was documented in several wells. LNAPL was present in MW-25. Arcadis will continue with annual groundwater monitoring and will prepare a conceptual site model report in 2013. Robert Burgess
5/14/2014 Meeting or Teleconference Held DEC met with Chevron and ARCADIS to discuss the status of several Fairbanks-area sites. Current plans for this site are to continue annual groundwater monitoring. Nearby sites are a higher priority for Chevron, and heavy hydrcarbons in the diesel range (DRO) are the primary contaminants. DRO does not respond well to air sparge or soil vapor extraction treatment, so monitored natural attenuation may be the most likely long-term remedy for this site. Robert Burgess
1/12/2016 Report or Workplan Review - Other DEC reviewed the Annual 2015 Groundwater Monitoring Report covering this site and an adjacent site. Contaminant concentrations and groundwater gradient are consistent with past events. Robert Burgess
10/6/2016 Meeting or Teleconference Held Meeting with RP and consultant on multiple Chevron sites to discuss current site status and upcoming site action. Shawn Tisdell
