| 9/11/2008 | Update or Other Action | On 9/11/08, DEC issued a letter to John Pontus in response to telephone calls John made to DEC within the last week requesting closure of his site. DEC's file was missing so it could not close the file but John provide a Gilfilian report of a cleanup performed in 1992. That report showed that about 35 cy of petroleum contaminated soil was excavated and DRO remained up to about 3,810 mg/kg. John also noted that because elevated contaminantion remained, Gilfilian performed another cleanup that removed an additional five truckloads of contaminated soil. Soil from the second removal was mixed with the first removal and stockpiled on site. John further noted that after about 10 years, someone (but he could not recall who) removed the stockpiled soil to an unknown destination. DEC's 9/11 letter requested clarification of the disposition of the stockpiled soil, and a copy of the report of the second cleanup and if not available provide DEC a workplan to characterize the site. DEC's letter also notified Pontus of the State's cost recovery requirements. In its letter, DEC noted that it had found the missing file it had on this site at its Wasilla office and it would be incorporated into DEC's Anchorage CSP office's file regarding this site. | Rich Sundet |
| 10/13/2008 | Update or Other Action | On 10/13/08, CS issued a letter to John Pontius that was in follow-up to his consultant ChemTrack Alaska, Inc.’s 9/29/2008 response to our letter dated 9/11/2008. In addition, the letter is in follow-up to an 10/1/2008 discussion Sundet had with Ms. Mary Shreves formerly of Gilfilian, Inc. (Gilfilian). Lastly, the letter was in follow-up to a review of the file on the property which was unavailable to CS when we drafted CS's September 10th letter but was located in our Wasilla office and has now been transferred to our Contaminated Sites Program in our Anchorage office. In my discussion with Ms. Shreves, she noted that she went through her notes and records that she had kept while working for Gilfilian. She also noted that Gilfilian had performed two excavations one on September 3, 1992 and another on September 24, 1992, and activities from both are discussed in the 1992 report. She did not recall or have any notes of any other cleanup work that she or Gilfilian had performed at the site. She believed that the two cleanups that Pontius was talking about were the ones in September 1992 and conveyed that information to you during a telephone conversation on September 29, 2008. CS surmised in its letter that it would appear that there were two excavations both in September 1992 but there was no follow-up excavation in 1993 or later. Further review of the 11/1992 dated Gifilian report showed that the site was not fully characterized and that PCE was detected at 0.261 mg/kg in sample S2, and extractable petroleum hydrocarbons (similar to DRO) was detected at 3,810 mg/kg. Therefore, DEC requested a workplan by 11/14/2008 to further characterize the site and provide information regarding the disposition of the 35-45 cy stockpile that had been on site after excavation activities in 1992. | Rich Sundet |
| 11/18/2013 | Document, Report, or Work plan Review - other | Reviewed work plan for Site Closure sampling for Allied Automotive. One borehole will be advanced at the location of the 1992 samples to delineate the extent of DRO and PCE contamination associated with the former floor drain outfall behind the building. | Bill O'Connell |
| 11/18/2013 | Document, Report, or Work plan Review - other | Reviewed Site Closure Sampling report for Allied Automotive. One borehole was advanced in the same location the 1992 samples. In the sample collected from 14-15 feet bgs, DRO was not detected and PCE was detected at 0.0285 mg/kg. In the sample from 20.5-21.5 feet bgs, contaminants were not detected. | Bill O'Connell |

| 11/25/2013 | 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 known as Allied Automotive Mechanics located at 1751 South Audie Street in Wasilla, 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 this site will be closed. | Bill O'Connell |
