Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 9/10/2007 | Update or Other Action | ADEC provides comments on the June 13, 2007 Work Plan For Cleanup Activities. The workplan proposes to excavate soil from some of the areas previously identified as being over cleanup levels, and install monitoring wells in some of the areas previously identified as having groundwater contamination. The RPs consultant is to provide a revised workplan. | Robert Weimer |
| 4/23/2008 | Update or Other Action | ADEC provides comments on the January 23, 2008 Revised Work Plan For Cleanup Activities. The workplan proposes to excavate soil from some of the areas previously identified as being over cleanup levels, and install monitoring wells in some of the areas previously identified as having groundwater contamination. | Robert Weimer |
| 5/15/2008 | Site Added to Database | Site added to the database. | Mitzi Read |
| 5/16/2008 | Exposure Tracking Model Ranking | Site ranked on the new Exposure Tracking Model (ETM). The ETM is a new site ranking system that looks at, based on available data, the potential exposure pathways for the contamination remaining at the site. | Mitzi Read |
| 6/22/2009 | Update or Other Action | ADEC provides comments regarding request to landspread as clean some of the soil excavated at the site. Those soils stockpiled soils need to be field screened and analytical sampled in accordance with an approved sampling plan, or be cosidered as contaminated for treatment. | Robert Weimer |
| 6/23/2009 | Site Characterization Report Approved | In August/September 2008 five test pits, one soil boring, and three monitoring wells were installed. A total of 75 cubic yards of contaminated soil was removed from the five test pits. Up to 112 mg/kg GRO, 488 mg/kg DRO, and 0.723 mg/kg benzene in the excavation soil samples collected. Some of the soil sample results are biased low because they we not properly preserved in the field. Up to 0.740 mg/l GRO, 1.98 mg/l DRO, 5.00 mg/l RRO, and 28 ug/l benzene in the groundwater samples collected. The 75 cubic yards of excavated soil is currently stockpiled on site in a 50 cubic yard and a 25 cubic yard stockpile. Additional site characterization, corrective action, and groundwater monitoring is needed. | Robert Weimer |
| 6/24/2009 | Update or Other Action | ADEC approves request for thermal treatment of 75 cubic yards of excavated soil that is currently stockpiled on site in a 50 cubic yard and a 25 cubic yard stockpile, and 1 drum of contaminated drill cuttings. | Robert Weimer |
| 10/28/2011 | Update or Other Action | To date no documentation that additional site characterization, corrective action, and groundwater monitoring have been provided. | Robert Weimer |
| 1/30/2014 | Update or Other Action | Project manager changed to Amy Dieffenbacher, transferred to Juneau | Annie Ariel |
| 9/30/2014 | Potentially Responsible Party/State Interest Letter | Telephone call to RP, left message on executive assistant's line. Mailed potentially responsible party (PRP) letter to RP. | Amy Rodman |
| 12/10/2014 | Update or Other Action | Received email from RP with 2009 AK Soil Recycling report re: excavated soil remediation status. Email requested site closure with "NFA/Clean up Complete" status. | Amy Rodman |
| 1/23/2018 | Update or Other Action | Site summary/work plan request letter emailed to RP. Updated deadline for work plan is May 18, 2018. | Amy Rodman |
| 5/24/2018 | Site Characterization Workplan Approved | Work plan approved with comments. Proposed activities generally consist of advancing two soil borings, field-screening soil with a photo-ionization detector (PID), installing two temporary groundwater monitoring wells, collecting soil and groundwater samples, decommissioning the temporary groundwater monitoring wells, laboratory analysis of soil and groundwater samples, and managing investigation-derived waste (IDW). | Amy Rodman |
| 11/8/2018 | Site Characterization Report Approved | ADEC reviewed and approved the “Report for Alaska Waste Rosewood Facility Site Characterization” (report) dated September 28, 2018 for the JL Properties – 6301 Rosewood Street site in Anchorage, AK. The report was submitted via email on October 11, 2018 by Restoration Science & Engineering, LLC. The described field effort was conducted on July 10, 2018 and generally consisted of advancing two soil borings, temporary groundwater monitoring well installation at each soil boring location, field-screening soil with a photo-ionization detector, and sample collection (soil and groundwater) for laboratory analysis. | Amy Rodman |
