Problems/Comments
On 11/21/13 approximately 130 gallons of diesel fuel was released from a fitting in the fuel line leading to an underground heating oil tank at Jillian Square Apartments Building A Pod 2. Fuel was released to the subfloor, structural supports, and the floor of the crawlspace. Initial response actions included temporarily relocated affected residents until air quality returned to background levels, removal of approximately 22 cubic yards of contaminated soil and installation of a temporary crawlspace ventilation system. Excavation was limited due to structural considerations. Following the initial response, a vapor extraction system, vapor barrier and concrete cap has been permanently installed in the crawlspace and ventilated above the apartment building.

| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 3/28/2014 | Spill Transferred from Prevention Preparedness and Response Program | Spill transferred by PERP staff Paul Lhotka. Spill no. 13309932502; spill date = 11/21/13; substance = diesel; quantity = ~130 gallons; source = failure of fitting on fill line to heating oil underground storage tank; PERP file no. 102.02.001. | Mitzi Read |

| 4/3/2014 | Exposure Tracking Model Ranking | Initial ranking with ETM completed for source area id: 79621 name: ~130 Gal Diesel from Line to Heating Oil UST | Mitzi Read |
| 8/6/2014 | Site Characterization Workplan Approved | Work Plan for Site Assessment reviewed and approved. | Willett Boger |
| 9/18/2014 | Potentially Responsible Party/State Interest Letter | PRP letter sent to Responsible Party. | Willett Boger |
| 8/8/2016 | Site Visit | Staff from DEC met with Nortech and Jillian Square Apartments staff to discuss site status and possible action timelines. PID measurements were taken from locations that had previously been impacted by vapor intrusion. Air measurements for volatile organics did not exceed 1 ppm except beneath the vapor barrier in one area. This is in contrast to the initial readings shortly after the spill which ranged up to 15 ppm. Nortech will be submitting a work plan to the DEC reflecting what was discussed at the visit. | Shawn Tisdell |
| 8/12/2016 | Site Characterization Report Approved | A Corrective Action and Site Characterization report prepared by Nortech on July 26 was reviewed and approved. The report documented activities conducted at the site and proposed additional remediation and management strategies to control exposure risk at the site. A work plan was requested to provide details the installation of a vapor mitigation system, backfilling of the crawlspace and the air sampling methodology. | Shawn Tisdell |
| 8/29/2016 | Document, Report, or Work plan Review - other | The Site Mitigation Work Plan dated August 26, 2016 was reviewed and approved. Work plan tasks include 1) an additional groundwater monitoring event from the temporary well (to be decommissioned if clean); 2)the vapor extraction system (VES) will be modified for potential long-term use and covered with vapor barrier and concrete; 3)air will be tested in the crawlspace for petroleum vapors using EPA the TO-17 method; 4)Documentation of the three tasks as well as of the operation and maintenance of the VES and any additional site monitoring requirements will be provided. | Shawn Tisdell |
| 9/23/2016 | Site Visit | Staff from DEC met with consultant to view work done at site and air sampling event. Since the previous visit, pea gravel, a vapor barrier and slab had been installed. The vapor extraction system was prepared, but not running so that representative air samples could be taken. Air sampling was using active sorbent samplers to be analyzed by the EPA Toxic Organic (TO)17 method. | Shawn Tisdell |
| 10/10/2016 | Exposure Tracking Model Ranking | A new updated ranking with ETM has been completed for source area 79621 ~130 Gal Diesel from Line to Heating Oil UST. | Shawn Tisdell |
| 10/31/2016 | Document, Report, or Work plan Review - other | 2016 Mitigation Report received by DEC and is under review. | Shawn Tisdell |
| 11/3/2016 | Document, Report, or Work plan Review - other | An October 31, 2016 mitigation report prepared by Nortech was reviewed and approved by DEC staff. The report indicated that site work associated with installation of the vapor mitigation system and vapor extraction system (VES) is completed. The VES can exhaust petroleum vapors from beneath a vapor barrier, through an insulated chase to the building roof. The system is to be used as indicated in a VES Operations and Maintenance Manual that was prepared by Nortech for Jillian Staff. No additional site work is recommended, and Nortech recommends Jillian Square Request site closure. | Shawn Tisdell |
| 11/21/2016 | Cleanup Complete Determination Issued | The Alaska Department of Environmental Conservation, Contaminated Sites Program (ADEC) has completed a review of the environmental records associated with the site Jillian Square Apartments Bldg A Pod 2 located in Fairbanks, Alaska. Based on the information provided to date, it has been determined that the contaminant concentrations remaining on site do not pose an unacceptable risk to human health or the environment and no further remedial action will be required unless new information becomes available that indicates residual contaminants may pose an unacceptable risk. | Shawn Tisdell |
