Cleanup Level(s) Approved |
Teleconference with Reinsma. See my site log this date for details. |
Bill Janes |
10/30/2000 |
Site Characterization Report Approved |
Teleconference with Reinsma. Changing recommendations in report. RRM now to say something such as "no immediate remediation but in the event that it is necessary Chevron will be prepared to move forward" in order to remove the implication that they are seeking a NFRAP at this time.
Get idea of where GW contamination is, at what levels to take into account seasonal fluctuations, and to determine if point of compliance is being met at the property boundary. Four quarters of monitoring thru 3rd quarter of 2001. More wells could potentially be placed depending on the results of each quarterly event.
Subsurface soil GRO and DRO contamination above table B2 levels - Dave to integrate into report why excavation should not be done right now. I will look into details of regulations to see if we can find a way to leave this contamination in place as it does not appear problematic. Told Dave that perhaps FW could extrapolate the results of the Willoughby risk assessment work to the airport situation since sub-surface soil contamination also remains at the Willoughby site. |

Bill Janes |
3/22/2001 |
Update or Other Action |
Final report on additional assessment and soil remediation dated 12/19/00 received January 4, 2001. Approximately 1000 tons of soil above method 2 for benzene, GRO, DRO estimated to remain. RRM recommends no further active remediation of the material because it is in the GW smear zone. Continued GW monitoring recommended. Drafted an email to RRM expressing my concerns.Not enough documentation showing that contamination was removed to the maximum extent practicable. |
Bill Janes |
5/10/2001 |
Update or Other Action |
Teleconference with Reinsma. Agreed to put project on hold regarding additional cleanup of soils for now. Cochran to communicate with airport regarding leaving it in place.

Update or Other Action |
Email from Reinsma. Based on four quarters of data from June 2000 to June 2001, hydrocarbon concentrations in the four site wells are stable and decreasing. Three out of four wells have values well below Table C cleanup levels. The only well that does not meet Table C levels is the source area well that is screened in perched groundwater.
RRM recommends annual groundwater monitoring for this site starting next year. Delta/RRM will be submitting the second quarter 2001 monitoring report with this recommendation to ADEC shortly. This will be the last report for this site during 2001.
RRM/Delta will also be submitting a project status update document to the Juneau Airport administration office summarizing past assessment and remedial activities, current soil and groundwater conditions, future groundwater monitoring plans, and notification protocol for future possible development activities at the site. |

Update or Other Action |
Telecon with David Wiegner of SECOR. Proposed September monitoring at what we thought would be low water table and thus below smear zone will be placed on hold. Historic data shows September is not a low water table period. We will probably not be able to get below the smear zone as we thought we could. David will discuss with Stacie H. at Chevron and get back to me. |

Document, Report, or Work plan Review - other |
Conestoga Rovers & Associates has reported the results of environmental site activity in 2012. DEC letter accepts the current evaluation of ongoing remediation of petroleum contamination performed by CRA for Chevron using a solar panel powered ozone injection system. The current results indicate that the cleanup remedy has stabilized contamination at levels that may be acceptable for regulatory site closure with institutional controls controlling any off-site transport of soil and/or groundwater and the installation of wells to access and use groundwater. If the land manager (City and Borough of Juneau) finds the controls are consistent with the Airport Management Plan then an agreement can be reached. |

Document, Report, or Work plan Review - other |
DEC evaluated the CRA Sampling Report for 2013 site activity at the JIA Fuel Facility for CS Program approval criteria. A Report Approval letter was sent by regular and electronic mail to Dan Carrier at Chevron copied to consultant Conestoga Rovers & Associates project manager Darek Wilken, Juneau Airport Manager Patricia deLaBruere and Delta Western Environmental Manager Bev Niemann. Consistent with previous correspondence, the DEC letter accepts the current evaluation of ongoing remediation of petroleum contamination performed by CRA for Chevron using a solar panel powered ozone injection system. Although only an estimate due to laboratory quality deficiencies, the 2013 results indicate that contamination is at levels that are acceptable for regulatory site closure with institutional controls (ICs) on the property. ICs include standard conditions for a contaminated site (controlling any off-site transport of soil and/or groundwater) and in addition a restriction that the installation of wells to access and use groundwater be coordinated with the CS Program. If the JIA Manager and Board (City and Borough of Juneau) find these IC controls are consistent with the Airport Management Plan then a closure determination can be achieved. |

Document, Report, or Work plan Review - other |
DEC reviewed the letter/report: Annual 2014 Groundwater Monitoring Report (Report), dated November 5, 2014 and provided approval by letter mailed today to Chevron and copied by electronic mail to the CBJ Juneau International Airport (JIA) Manager, the Delta Western Environmental Manager and Conestoga-Rovers & Associates Inc. (CRA). CRA completed the report documenting sampling activity at the Site. The site activity met the objectives of the approved work plan and the Report data is of sufficient quality for use in the decision making process. In accordance with 18 AAC 75.360, qualified person(s) performed data collection consistent with DEC methodology. The DEC laboratory report checklist indicate the data meet Contaminated Sites Program quality assurance criteria, therefore the Report is approved in accordance with 18 AAC 75.335(d). The CRA Report stated that conversations with the JIA Engineer Ken Nichols on June 2, 2014 indicated that the Master Plan for the airport is currently being written and is projected to be completed in approximately 2 years. Chevron and CRA will continue to work with the JIA to ensure implementation of the Institutional Controls denoted in the DEC's May 12, 2014 correspondence. |
