Problems/Comments
Site was utilized during construction of Alyeska Pipeline. Observed soil staining in various locations throughout the pad. Suspected buried wastes.

Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 3/13/1995 | Site Added to Database | Soil staining. | Scott Rose |
| 10/1/1995 | Site Characterization Workplan Approved | Site investigation workplan was approved and conducted during October 1995. Contamination was identified that warranted additional investigation. | Jim Frechione |
| 10/12/1995 | Preliminary Assessment Approved | Term Contractor (E&E) was contracted to perform a preliminary assessment on this site. Site is a DNR Memorandum of Agreement site. | Scott Rose |
| 4/21/1998 | Site Ranked Using the AHRM | Ranking action added now because it was not added when the site was originally ranked. | Bill Petrik |
| 10/1/1998 | Site Characterization Report Approved | Additional areas of contamination were identified that exceed the most stringent migration to groundwater levels. However, risk based cleanup levels may be applicable due to the remote nature of the site. | Jim Frechione |
| 12/8/1999 | Update or Other Action | ADNR owns and manages the property. They objected to the use of risk based cleanup levels because of the effect higher contaminant levels have on the value of the property. | Jim Frechione |
| 12/13/1999 | Update or Other Action | ADEC letter to Alyeska Pipeline Service Co. regarding need for additional information and request of landowner (ADNR) to require most stringent cleanup levels. ADEC requests Alyeska intentions on this matter. | Jim Frechione |
| 1/8/2001 | Update or Other Action | ADEC received a letter from Alyeska. IT completed a soil boring at the Isabel Pass Camp to confirm the depth to groundwater. According to the soil boring logs that were submitted with the letter, no groundwater was found down to 50' below ground surface. | Deborah Williams |
| 1/12/2001 | Institutional Control Record Established | Institutional Controls Established for the site. | Deborah Williams |
| 1/12/2001 | Conditional Closure Approved | ADEC issued a no further remedial action on this site. Alyeska paid for additional sampling in order to receive a NFRAP determination. The fact that no groundwater was detected 0 - 50' below ground surface, was applied to the October 2000 soil attenuation model using the maximum soil contamination identified at the site. It was concluded that the soil contaminant concentrations would not pose a risk to groundwater and other possible pathways (ingestion and inhalation). | Deborah Williams |
| 11/5/2003 | Update or Other Action | Changed Justification to "N" because the site is in NFRAP Status. | Former Staff |
