Update or Other Action |
JBC Entry - I have coordinated with the RP on this site, and have indicated that they are ready for closure it they address the small contaminated stockpile onsite. They indicated that this is a very low priority with them, although I indicated it would be cost effective to deal with at this time. |

Site Reopened |
In 2009, the same 10,000-gallon diesel tank (UST #2) was temporarily taken out of service while some piping was removed during the installation of a new aboveground tank south of the UST. In February, 2012 the UST Program issued a notice of non-compliance requiring the tank to be permanently closed. Based on information gathered during site assessment activities in October 2012, the site is being reopened. Petroleum contamination was confirmed above DEC cleanup levels in soil and groundwater. |

Underground Storage Tank Site Characterization or Assessment |
Reviewed UST Site Assessment Report completed by Shannon & Wilson for DOT in October 2012. An in-place closure site assessment was completed because the tank is located in a tight location surrounded by security fencing. S&W installed three borings and found near-surface soil contamination at the north end of the UST and subsurface soil contamination south of the UST. A monitoring well (MW-1) was installed south of the UST. Groundwater samples from MW-1 contained DRO up to 14.7 mg/L. Sections of remaining piping were also pressure tested and were determined to be tight. |

Meeting or Teleconference Held |
Met with Department of Corrections, Department of Tranportation, and UST Program to discuss the 10,000-gallon UST site assessment results. DOT/DOC plans to contract with Shannon & Wilson to complete cleaning and filling of the UST, further investigate the release to by installing at least two monitoring wells northwest of MW-1, and to excavate near surface contaminated soil at the north end of the tank. Removal of the tank to expose the deeper contaminated soil observed at the south end of the tank is complicated by the security fence which cannot be undermined or comprised through excavation deeper than a couple of feet. DEC requested a workplan and explained GRO should be retained as a COC until further characterization is completed. |

Document, Report, or Work plan Review - other |
Received workplan for completing the in-place UST closure by removing fuel, excavating to top of tank, and purging and filling the tank. Soil will be screened with a PID and contaminated material will be taken to OIT for thermal remediation. DEC approved the workplan and provided soil transport approval at the same time. |

Document, Report, or Work plan Review - other |
Shannon & Wilson (S&W) submittal of Underground Storage Tank Closure Report received and reviewed. The report summarized the in-place closure of the 10,000 gallon diesel underground storage tank (UST) a the Fairbanks Correction Center (FCC). S&W contracted with Inland Petroservice (IPS) and completed in-place closure on July 3, 2013. On July 5, 2013, the tank was filled with concrete grout using a pump truck. IPS also backfilled the excavation with the excavated soil. Conclusions and recommendations note that no contaminated soil was encountered during work. It is recommended that a release investigation is carried out to evaluate the extent of soil and groundwater contamination associated with the UST. |

Update or Other Action |
Sent letter to Department of Corrections requiring additional release investigation to determine the extent of groundwater contamination. The letter requested a workplan be submitted in August 1. |

Update or Other Action |
Release investigation workplan submitted by Shannon & Wilson. Two borings/monitoring wells will be installed to investigate extend of soil and groundwater contamination associated with 10,000 gallon tank that was closed in place. BTEX, DRO, GRO, and PAHs will be analyzed. Work planned for summer 2017, although DOC does not have identified funding yet. |

Update or Other Action |
Contacted Shannon & Wilson to check on the pressure testing completed on the piping runs in 2011. Piping between the UST and the Prison Industries Building initially failed the hydrotstatic pressure test, when the test was performed at the Prison Industries Buildings. However, it was determined that the piping had been cut at the UST, and once the cut piping was sealed off, the lines passed pressure testing. |

Document, Report, or Work plan Review - other |
DEC provided comments on the November 2016 workplan for release investigation in a letter to Dan Aicher at the Alaska Department of Corrections. DEC requested that the proposed monitoring wells locations be moved closer to the closed UST and that groundwater flow direction and gradient be reported. DEC will require at least two groundwater sampling events to evaluate seasonal conditions. |
