Update or Other Action |
Sundet discussed site with Jerome Summerlin of Padre Associates, Baker Hughes consultant. Subsequently, Summerlin faxed to Bill Janes and Sundet a VCP application. Summerlin also noted that Padre had performed an assessment of the site in 2000. Two contaminated sites exist on Tract 12 (AMENDED-One site on Tract 12, one site on Tract 73A. THIS SITE is on Tract 73A, not Tract 12. (O'Connell 5/4/06)) Summerlin noted that he would mail copies of the EA to Janes and Sundet for their review as it would be an attachment to the VCP application. |

On 8/23, Sundet discussed the VCP application with Gary Schultz and Leon Lynch of DNR and provided them a draft copy of DEC's acceptance letter for the site into the VCP. DNR had no objections other than it appeared that the site was on either Tract 73a or 73b and not on Tract 12.
On 8/23, Sundet discussed via phone with Summerlin that ADEC had reviewed the file and VCP application and was preparing to send a letter to Baker Hughes accepting the site into the VCP. However, it appears that the Northern Test Lab specified to be used in the work plan at Deadhorse is not approved by DEC, but its offices in Fairbanks and Anchorage are approved. The Deadhorse lab could be used to verify PID sample results but not be used for confirmation purposes. Summerlin acknowledged this and noted that he would use the Deadhorse lab only as a portable lab and confirmation samples would be sent to one of the approved Northern Test Labs. Sundet also informed Summerlin that DNR had reported that the site appeared to be on Tracts 73a or 73b and not on Tract 12 as the application stated. Summerlin confirmed that the site was probably on either of the two tracts on 73 and that other contamination problems exist on Tract 12, which are not part of the scope for this project.
Later on 8/23, ADEC issued a letter to Baker Hughes accepting the site into the VCP with conditions. |

GIS Position Updated |
Improved the latitude and longitude using area parcel maps in conjunction with TopoZone Pro. Obtained coordinates at 1:25,000 Scale and plotted at 1:50,000 Scale on a 1:24,000 Scale USGS Topo Base Map on a Large Size Map. NAD 83. Coordinates are only approximate, have a low degree of confidence in accuracy, and need improvment. |
