Teleconference with Marty Cramer with Phillips Conoco. Apparently there are some legal agreements between Unocal, Conoco (Tosco was bought by them) and Bill Privitt, current owner, transferring environmental liability. Marty is working with his legal staff and will be back in touch as soon as he has something to report. |

Update or Other Action |
Telecon with Bill Privitt at Wrangell Oil to let him know that DEC will not be requiring an interception trench between Wrangell Oil and the adjacent, downslope Delta Western facility. Contamination above the Del West facility appears stable at this time and is like small volume. Trenching behind the Del West facility could compromise the facility's new secondary containment liner. |

Potentially Responsible Party/State Interest Letter |
DEC staff issued a potential responsible party letter to Mr. William Privett of Wrangell Oil Inc. DEC informed Mr. Privett of DEC's cleanup process and requested that he respond in writing by July 30, 2010, on his attempts to investigate or treat contaminated soil since 2003. |

Update or Other Action |
DEC issued a letter to Bill Privett comenting on his May 7, 2010 letter. In Mr. Privett's letter he suggests that excavation of contaminated soil is impractical due to the presence of steep slopes and a shale rock ledge. In our letter, we notified Mr. Privett that we will not require he hire a qualified person to excavate any existing contaminated soil. However, we did request that he characterize the contaminated soil further (i.e. identify the nature and extent of contamination). Further characterization of contaminated soil and groundwater is necessary for a closure determination to be issued. By our letter, we requested Mr. Privett hire a qualified person to issue a site investigation work plan to CSP for our review and approval. The deadline for submittal of the work plan is October 31, 2010. |

Site Characterization Workplan Approved |
DEC reviewed and conditionally approved Carson and Dorn, Inc.’s “Site Investigation Work Plan, Wrangell Oil, Inc.”, dated October 2010. Within the plan, Carson and Dorn Inc. (CDI) propose to collect soil samples from ten locations on the Wrangell Oil Facility. CDI will collect soil samples by advancing a soil boring and retrieving samples in a bucket auger or split spoon sampler. Alternatively, they may excavate test pits with a back hoe and collect samples from the excavation pit. Soil samples would be analyzed for GRO, DRO, BTEX, and RRO by DEC approved methods. CDI also proposed to install two stainless steel drive-point piezometers utilizing a slide hammer. Groundwater samples will be collected from the installed piezometers to be analyzed for GRO, DRO, RRO, and BTEX. DEC approved of the work plan in a letter dated December 13, 2010 provided CDI:
1. Collects soil and groundwater samples in accordance with DEC’s May 2010 Draft Field Sampling Guidance.
2. Installs and develops piezometers in accordance with DEC’s February 2009 Monitoring Well Guidance.
3. Completes CSP’s data review checklist for each laboratory received and submits copies of the checklists in their final report.
4. Constructs a preliminary conceptual site model (CSM) in accordance with DEC’s November 2005 Guidance and provides the CSM in their final report.

Cleanup Complete Determination Issued |
Petroleum contamination remains in sub-surface soil and groundwater above approved cleanup levels. Sub-surface soil contamination is located near the shop building and must be evaluated when the building is removed and/or the soil becomes accessible. All groundwater monitoring wells associated with the site must be properly decommissioned and a report documenting decommissioning submitted to ADEC by August 1, 2014. Any proposal to transport soil or groundwater off-site requires ADEC approval. Wrangell Oil, Inc. will report to ADEC every 5 years to document land use or changes in land ownership. |
