Problems/Comments
Six underground storage tanks removed in 2000. 275 cubic yards of DRO contaminated soil removed and thermally treated at OIT. Four tanks were 4,500 gallons, one tank was 1,500 gallons, and one tank was 10,000 gallons. Tank locations were located at Michaels, the Bently Mall, Safeway, The east and west satellite buildings and the National Bank of Alaska. All tank excavations met soil cleanup levels of less than 200 mg/kg DRO except the Michaels tank (4,500 gallons). Localized contamination left in place per the recommendation of structural engineer to prevent undermining of building foundation. Analytical from edge of excavation was 5,870 mg/kg ten feet bgs.Contamination is thought to be from fuel transfer activities rather than a leak. No soil analysis for BTEX or PAHs, no groundwater sampling.
Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 9/2/1996 | Site Added to Database | Phase I ESA completed for Bentley Mall property by Nortech. Recommends testing the underground heating oil tanks for leaks. Added in 2007 to reflect administrative file. | Shannon Oelkers |
| 12/20/2000 | Update or Other Action | All tank excavations met soil cleanup levels of less than 200 mg/kg DRO except the Michaels tank. Localized contamination left in place per the recommendation of structural engineer to prevent undermining of building foundation. Analytical from edge of excavation was 5,870 mg/kg ten feet bgs. Added in 2007 to reflect administrative file. | Shannon Oelkers |
| 12/20/2000 | Site Characterization Report Approved | Site Assessment and tank removal report received for 6 underground storage tanks used for heating oil located at the Bentley Mall property. Added in 2007 to reflect administrative file. | Shannon Oelkers |
| 12/20/2000 | Update or Other Action | BTEX and PAHs were not analyzed. Table 2 (page 54) of the Underground Storage Tanks Procedures Manual indicates that DRO, BTEX and PAH lab analysis be done on soil and groundwater samples. If #3-#6 fuel oils are used, RRO analysis must also be performed. Added in 2007 to reflect administrative file. | Shannon Oelkers |
| 12/20/2000 | Update or Other Action | 275 cy of contaminated soil disposed of at OIT facility. ADEC approval not obtained before transport. New tanks were installed at old tank locations, backfilled with clean soils and re-paved. It is unknown what size and construction type the tanks were. Added in 2007 to reflect administrative file. | Shannon Oelkers |
| 3/30/2001 | Site Ranked Using the AHRM | Preliminary ranking. Headwaters of Isabella Creek may or may not be evident in the immediate area of the site but has hydrological connection to stream flowing north through the Bentley Trust Tax Lot 201 (2000310925901). | Bruce Wanstall |
| 7/10/2002 | GIS Position Updated | Changed the Latitude, Longitude, Method Accuracy, Accuracy and Unit fields. | Heather Goldman |
| 1/23/2007 | Update or Other Action | Updated to reflect administrative file. | Shannon Oelkers |
| 1/24/2007 | Update or Other Action | Spoke with Doug Bauer. Groundwater monitoring associated with the East Satellite solvent plume are too far away to provide useful information. | Shannon Oelkers |
| 4/25/2007 | Update or Other Action | Received Alaska Resources and Environmental Services letter report titled Ground Water Results fro Michael's Building dated 4/25/2005. A ground water monitoring well was installed hydraulically down gradient from the Michaels store's heating oil UST. Results indicate no impact to ground water from former tank excavation and residual soil contamination beneath Michaels store's northwest corner. | Douglas Bauer |
| 4/27/2007 | Update or Other Action | A lab QA/QC review revealed that the LCS and LCSD out of control for the ARES 4/25/2007 report. ARES advised to re-sample the Michaels' ground water monitoring well. | Douglas Bauer |
| 5/4/2007 | Update or Other Action | ARES reports that the re-sampled ground water results indicate no impacts to ground water and lab QA/QC is good this time. | Douglas Bauer |
| 5/4/2007 | Conditional Closure Approved | Conditional Closure issued. See attached letter and NEC. | Douglas Bauer |
| 5/4/2007 | Institutional Control Record Established | Administrative update (10/25/07) | Evonne Reese |
| 7/2/2012 | Update or Other Action | Staff changed from Ann Farris to IC Unit. | Kristin Thompson |
| 7/3/2012 | Institutional Control Compliance Review | An IC review was conducted on this site and the reminder system was updated with follow up requirements. A search for a recorded deed notice will be conducted at the Recorder's Office. | Evonne Reese |
| 5/14/2015 | Institutional Control Update | After a file review it was found that the 2007 Notice of Environmental Contamination was never filed with the Recorder's Office. A copy of the document was sent to the Recorder's Office for filing. | Evonne Reese |
| 7/13/2015 | Institutional Control Update | Received the recorded Notice of Environmental Contamination from the Recorder's Office. | Evonne Reese |
| 11/29/2018 | Institutional Control Compliance Review | IC compliance review conducted. Contact information updated. Reminder system set to follow-up with landowner in 5 yrs. | Mossy Mead |
| 2/23/2023 | Institutional Control Compliance Review | IC compliance review conducted on this date and a reminder letter was issued. The next compliance review will be in 2028. | Jennifer McGrath |
