Site Visit |
Site visit on 5/14/99 by Dick Farnell & Sally Schlichting of DEC and Jason Ginter consultant. Viewed former UST location and confirmed improbability of contamination detected at UST closure as coming from UST due to elevation differences and lateral distances. Letter sent to Delta Western 5/21/99 stated that contamination found did not come from the UST, but that release investigation still needed (by property owner - City) to determine nature and extent of contamination. City (Alan Heese of Airport staff) was encouraged to take a groundwater sample from point of groundwater flow exit into construction excavation for Duck Creek culvert installation to check for petroleum. Case still open. |

Underground Storage Tank Site Characterization or Assessment |
RRM Assessment for Chevron advanced 14 borings to collect subsurface soil and water samples then sampled the contaminated material stockpile. Gasoline range hydrocarbons were detected at concentration of 2,120ppm in boring B-6-; 112ppm in B-7; 140ppm in B-8. GRO in ground water reached 500ppm in B-6, 13.8 GRO in B-7, 9.8 GRO in B-1 and 3.54 GRO in B-2. All DRO and RRO samples were treated by silica gel before analysis; not the GRO samples. Most stringent cleanup levels for contaminated media are recommended for a residential exposure scenario. |

Leaking Underground Storage Tank Corrective Action Underway |
Meeting with Stacy Hartung-Freirchs (Chevron), John Riggi (Cambria), John Cooper (Cooper Consulting Engineer Inc), Bill Janes and Bruce Wanstall concerning new construction on Lots 5 & 6 that is adjacent to the subsurface petroleum smear zone on Lot 8B. Wanstall and Cooper inspected the site in the afternoon; Wanstall assumes site project management. |

Site Visit |
Attended soil boring site investigation at the facility with airport personel and Cambria Environmental representing Chevron Environmental. The pattern of subsurface contamination appeared consistent with conclusions arrived at during the April boring inspection. Samples were collected for laboratory analysis from Lots 5 & 6 in the JIA Fuel Facility proposed new development area. |

Release Investigation |
Meeting with Cooper Engineering, Chevron, Delta Western, and Juneau International Airport staff to develop plans to address a pocket of contamination at the facility that intersects with a current development project. |

Release Investigation |
The ADEC and Chevron met with the Juneau Airport Board of Directors to review the proposed plans for future development of the properties that comprise the facility. The ADEC had requested development of a management plan in the event that petroleum contaminated material is encountered on Lots 5 & 6 during development related earthwork activities. Chevron introduced plans to install an ozone injection remedial system for reducing dissolved-phase hydrocarbons in groundwater in site monitoring well MW-4. |

Release Investigation |
Plans for development involving earthwork on Lots 5 & 6 at the JIA facility are presently on hold. A low flow ozone diffuser equipped with a solar panel is a remedial strategy under consideration by Chevron to reduce diesel range hydrocarbons in shallow subsurface soil and groundwater at the site. |

Document, Report, or Work plan Review - other |
ADEC approved field and laboratory data in Annual 2009 Groundwater Monitoring Report and Ozone System Maintenance Report by Conestoga Rovers & Associates. Diesel contamination of ground water is in stable in concentrations still exceeding regulatory cleanup levels. Active treatment and monitoring will continue in 2010. |
