Groundwater Sampling Report received. The report states that 13 soil borings and 6 monitoring wells were installed in August 2004. The highest contaminant levels were observed in boring MW-1. Soil from the boring taken at 4 ' bgs contained 30,900 mg/kg DRO and exceeded clean up levels for GRO and BETX analytes. Groundwater contamination in MW-1contained 27,200 and 33,400 ug/L GRO and Diesel respectively in 2004, all BETX analytes exceeded cleanup levels; benzene was observed at 1,770 ug/L. Analytes in this same MW were significantly lower during the 2005 sampling event. GRO and DRO were 9,000 and 436 ug/L respectively. MW-1 is near the property boundary along Airport Industrial Road. The FIA Fuel Hydrant pipeline runs approximately 15' to the southeast of MW-1 and could potentially be contributing to contamination at the site. |

Meeting or Teleconference Held |
Janice Wiegers, and Kim DeRuyter met with Gerald O'Regan (ChevronTexacon) and Steve Krci k Red Hills Environmental) to discuss further delineation at the site. Groundwater contamination at MW-1contained 27.2 mgL GRO, 33.4 mg/L DRO in August 2004. MW-1 is placed near the location of an elbow in a former fuel line which transferred fuel from the ASTs to a fuel dispenser. The FIA - Fuel Hydrant line ran through this property not far from MW-1 also. Gerald agreed to further delineate groundwater contamination in this area though he did feel that contamination could be the result of non-Texaco sources. |

Update or Other Action |
Groundwater (GW) Sampling Report - September 19, 2005 Sampling Event received. The significant difference between this sampling event and the previous data is the lack of GRO in MW-1, and MW-3. Also, DRO and RRO are notably absent from MW-2. The depth to water was about midrange between previous high and low groundwater elevations at this site. GW elevation measurements continue to support previous evidence that GW flow in this area is to the SE. This is the opposite direction of the groundwater flow direction at sites nearby. However, GW gradients in this area are very flat. |

Site Characterization Workplan Approved |
Site Characterization report received from Brady Nagle at SAIC. The workplan outlines 5 tasks:
Task 1 - create a CSM which will compare site conditions to cleanup levels and evaluate potential risk to human and ecological receptors; and evaluate the need for ICs.
Task 2 - obtain permits and locate utilities; prepare a health and safety plan
Task 3 - perform a GORE survey to further delineate the contamination and determine if additional soil borings or GW wells need to be installed.
Task 4 - analyze the data
Task 5 - report data and consult ADEC regarding potential soil borings or GW monitor wells. |

Update or Other Action |
ADEC received the 2006 Groundwater Sampling Report for the Former Texaco Bulk Fuel Terminal. According to the report, groundwater samples were collected from wells MW-1 through MW-6. Groundwater samples were analyzed for GRO, BTEX, DRO, RRO, and selected VOCs. Concentrations of dissolved-phase benzene and GRO above ADEC cleanup levels during the July 27, 2006 sampling event were only detected in the sample from MW-1. The DRO,GRO and BTEX conc. at well MW-1 have shown a decreasing trend since monitoring began in August 2004. The levels above ADEC cleanup levels in MW-1 were 3.79 ppm GRO and 152 ppb benzene. |

Update or Other Action |
ADEC received a Soil Survey Assessment on the property. The conclusions of the report stated that the TPHd (diesel) is most highly concentrated at the eastern and northeastern border of the site, downgradient of the former USTs. Some TPHd mass is also concentrated southwest of the former pump house. A separate off-site plume appears to be located southwest of the site. A TPHg mass appears to be localized at one of the module locations east of the site just prior to Industrial Airport Road. BTEX was minimal at the site, with a localized mass east of the site near the TPHg mass. |

Document, Report, or Work plan Review - other |
DEC reviewed the First Semi Annual 2009 Groundwater Monitoring Report and Geochemical Parameter Monitoring results. Groundwater flow direction was to the south -southwest as opposed to the east -southeast observed during previous events. Wells MW3 and MW5 were not sampled due to the presence of ice. GRO and benzene exceeded cleanup levels in well MW-1. Geochemical parameters suggest aerobic conditions outside of the contaminated area and anaerobic conditions near well MW-1 (mostly based on methane and ferrous iron results). However, detectable amounts of methane were also observed in MW-5, were contamination has been non-detect. Arcadis recommends that future monitoring events are conducted later in the year when groundwater is less likely to be frozen and natural attenuation parameters may be more observable. |

Document, Report, or Work plan Review - other |
DEC received the Second Semi-Annual 2009 Groundwater Monitoring and Geochemical Parameter Monitoring Results from Arcadis. Well MW-1 was not sampled due to a light sheen. All contaminants were below cleanup levels in wells MW-2, MW-4, and MW-6. Only DRO exceeded the cleanup level in MW-3 and MW-5 with 2.64 ppm and 3.31 ppm respectively. Anaerobic biodegradation activities within the hydrocarbon plume could not be determined with the results obtained. |

Tamara Cardona-Marek |
| 8/28/2012 |
Meeting or Teleconference Held |
DEC met with Chevron and Arcadis to discuss actions for 2012-2013. Currently hand augered samples are being collected at the site to delineate contamination near MW-1 at different depths (particularly near 4 feet where contamination has been identified in the past). Results will help determine whether Chevron will request a cleanup complete determination. |

Meeting or Teleconference Held |
DEC, Chevron, Arcadis, and FIA met to discuss several Fairbanks area sites. Recent results for soil sampling at the site indicate that contaminants remain above direct contact levels in surface and sub-surface soils around MW-1 and the southeast property boundary. Because of the utilities in the area and the potential for workers to use the site, this is a current complete exposure pathway. Arcadis suggests to excavate soils from 0-2 feet with a vaccuum truck. Further excavation and other active remediation is not practicable because of the buried utility lines in this area, however airport staff is aware of the issue and will notify DEC and Chevron if utility work will take place in the area. Arcadis also suggested using surfactant and/or redeveloping MW-1 to enable a more robust evaluation of contaminant trends. |

Site Characterization Report Approved |
DEC reviewed the Annual 2013 Groundwater Monitoring report. The groundwater gradient was generally to the south, which is consistent with past groundwater monitoring events, but inconsistent with nearby sites at which groundwater flows west to northwest. MW-1 was the only well with contaminants above cleanup levels, including DRO at 234,000 ug/L, GRO at 10,100 ug/L, RRO at 1,400 ug/L, and Benzene at 80.9 ug/L. The only other well containing detectable concentrations of hydrocarbons was MW-3, which contained DRO below the regulatory limit at 830 ug/L. |

Meeting or Teleconference Held |
DEC met with Chevron and ARCADIS to discuss the status of several Fairbanks-area sites. Removal of contaminated surface soil and continued groundwater monitoring are planned for the near future at this site. Long-term plans may include monitored natural attenuation and/or institutional controls. |
Robert Burgess |
| 9/12/2014 |
Cleanup Plan Approved |
DEC reviewed and approved the 2014 Cleanup Plan after discussion and comment resolution with the ARCADIS project manager. Cleanup will consist of excavating surface soils to a depth of 2 feet to eliminate the direct contact and inhalation pathways for surface soil; sub-surface soil is not feasible to remove due to utility lines running through the contaminated area--it will be removed in the future if excavation occurs for utility upgrades or replacement. ARCADIS and Chevron propose that institutional controls will be placed on the property. |
