Meeting or Teleconference Held |
ADEC met with prospective purchaser of the property (Jeff Zuckerman) to discuss possible release from liability. Attorney General (Steve Ross) participated by phone. Mr Zuckerman was requested to provide proposal (eg. remove two heating oil tanks and contaminated soil) in exchange for possible release. |

Update or Other Action |
The prospective purchaser of the property (Jeff Zuckerman) had requested ADEC consider a release from liability for existing contamination. However, he purchased the property before an agreement was negotiated and proposed to remove the two tanks and assess the site for contamination |

Site Characterization Report Approved |
phase II assessment report by Alaska Resources & Environmental Services (Lyle Greshover) indicated the 2 heating oil tanks were removed. the soil data from the 1000 gallon tank did not exceed ADEC cleanup levels but the 300 gallon tank did. It was estimated that 296 cubic yards of soil was excavated. 80 cy were transported off site for thermal treatment and 216 cy were placed in treatment cell on site. The soil samples from the excavation (300 gallon tank) detected 1080 mg/kg DRO at the groundwater interface zone. Only one sample out of 7 exceeded ADEC cleanup levels. Groundwater was not sampled during this phase of the assessment |

Conditional Closure Approved |
the corrective actions to date resulted in the buildings being demolished; the heating oil tanks removed; the contaminated soil excavated (to the extent practicable) and soil treated both off and on site. the groundwater will be monitored in the future to determine quality conditions but there is no indication of off site migration or risk to humans (since groundwater is not used as drinking water). DEC approval is required for any off site transport of soil or groundwater |
Jim Frechione |

Institutional Control Record Established |
the conditional closure requires the following:
1. The soil treatment cell shall be operated and maintained until the soil contamination meets the established cleanup levels for this site or another alternative is proposed by the owner / operator of the property (and approved by ADEC). A post treatment sample plan shall be submitted to ADEC for review and approval prior to sampling.
2. The groundwater shall be monitored in a location hydrologically down gradient from the former tanks in accordance with a monitor plan submitted to ADEC (for review and approval) prior to implementation. The need for future monitoring will be determined by sample results.
3. A Notice of Residual Contamination will be established on the ADEC Contaminated Sites Database identifying the nature and extent of contamination remaining on site.
4. Any proposal to transport soil or groundwater off site requires the prior review (and approval) of ADEC in accordance with 18 AAC 75.325(i).

Update or Other Action |
AK Resources emailed results from sampling the soil that was landspread. DRO ranged from 320 to 669 mg/kg in the 5 samples collected. No BTEX was detected in the soil. One monitoring well was installed and sampled on June 12, 2009. Results indicate benzene at 82.8 ug/L. tolune and ethylbenzene also detected, but below MCLs. Consultant proposes to install 2 more wells. Options for the soil are being evaluated. |

Site Characterization Workplan Approved |
ARES installed two new permanent drive point wells at the site, one at the east edge of the property and one in source area. Staff approved the work plan for sampling the newly installed wells, MW-2 and MW-3. Additional comments were to survey all three wells to estimate gradient, develop CSM, and evaluate data from Gottshalks and Fairview Manor sites. Prelim data should be available by end of July. |

Long Term Monitoring Established |
Staff reviewed groundwater sampling results from July 2009. Three wells were installed this summer and sampled to satisfy a condition of the DEC closure. The upgradient well was clean. The source area well had DRO at 6.4 mg/L. The downgradient well had benzene at 83 ug/L. It appears the downgradient contamination may be from a different site, but semiannual sampling of these wells will continue for at least 2 more years. There is also still a soil treatment cell on site that must be maintained. |

Institutional Control Compliance Review |
IC compliance review conducted, verified the current property owner with the FNSB Tax Assessor's office, updated the Affiliates information in the database, set the reminder system to contact past stakeholders in this property to check on the status. The hardfile has been checked for useful information that was not included in the database record, but no luck. It is believed that the groundwater wells were destroyed or removed during the construction of the new building along with the repaving. Schedule to send an IC reminder letter and inquiry to the current landowner and verify that the building is on city water. |

Institutional Control Update |
I called the water company in Fairbanks and received confirmation that the building on this property is connected to the municipal water source. |

Institutional Control Update |
In response to the IC reminder letter, the property owners have consulted with Alaska Resource & Environmental Services (AK-RES) to address outstanding IC requirements at the site. AK-RES plans to conduct a site visit on April 15, 2016. Reminder system set to follow-up on the findings of the site visit. |

Document, Report, or Work plan Review - other |
A workplan for the re-installation of three monitoring wells to replace the wells that were paved over during the Airport Way Professional Building construction was approved on this date. |

Institutional Control Update |
We have received updated information regarding the soil stockpiled on site during the remediation effort. It was inadvertently moved by a construction contractor to his personal property during the building construction. Field screening was performed on the pile in 2009 by the property owners and the former ADEC project manager and no contaminated soils were identified. |

Document, Report, or Work plan Review - other |
IC Unit staff reviewed the December 2017 Groundwater Monitoring & Well Installation Report prepared by Alaska Resources and Environmental Services, LLC (ARES). Four analytical soil samples (including one blind field duplicate) were collected on September 20-21, 2016 and analyzed for GRO, DRO, BTEX, and PAHs. Soil analytical results were all non-detect or below ADEC cleanup levels at all sampling locations. ARES reinstalled three permanent groundwater monitoring wells at the site on September 20-21, 2016. The wells were developed on September 30, 2016, and sampled on October 14, 2016 and August 15, 2017. The wells were screened for NAPL prior to initiating sampling procedures, but NAPL was not detected in any of the wells. All three monitoring wells were sampled and analyzed for BTEX, GRO, and DRO. Groundwater analytical results for all three wells from the October 14, 2016 sampling event were all non-detect or below ADEC cleanup levels for all analytes tested, with the exception of MW-2 which had concentrations of DRO (1950 ug/L) above ADEC cleanup levels. Groundwater analytical results for all three wells from the August 15, 2017 sampling event were all non-detect or below ADEC cleanup levels for all analytes tested. ARES recommends one additional groundwater monitoring event to verify that the concentration of DRO in groundwater continues on a decreasing trend. |

Institutional Control Compliance Review |
A letter was issued approving the recommendations outlined in the 2017 Groundwater Monitoring & Well Installation Report submitted by ARES. One additional groundwater monitoring event will be required. An excavation/soil movement restriction was added as an institutional control for this site. Prior ADEC approval will be required should excavation of contamination soils in the vicinity of the source area be proposed in the future (such as for road construction, installation of utilities, etc.). All other institutional controls also remain in effect. The next groundwater monitoring event should be continued this field season (2018). |

Document, Report, or Work plan Review - other |
Reviewed the 2018 groundwater monitoring report. Monitoring wells #1, 2, and 3 were sampled for DRO, GRO, and BTEX. All concentrations were below Table C cleanup levels therefore future groundwater monitoring requirements are rescinded. A letter stating this was issued to the landowner. All other institutional controls are still in place and are applicable. |
