Problems/Comments
Historical petroleum contamination was discovered during new building construction activity at the site of the Former Colliseum Theatre in Sitka. Site Assessment indicated soil contamination begins at the corner with Lincoln Street and extends along the alley on the northeastern property boundary. Field screening of excavation soils on 11/18/02 segregated 120 cubic yards of soil above default Method 2 cleanup levels for petroleum. Soils were stockpiled on a liner on property owned by the Responsible Party on Charcoal Island in Sitka.
Action Information
Action Date | Action | Description | DEC Staff |
---|---|---|---|
11/18/2002 | Interim Removal Action Approved | Soils taken to Shee Atika property on Charcoal Island. | Bill Janes |
1/13/2003 | Site Added to Database | Historical petroleum release. | Bruce Wanstall |
1/13/2003 | Site Ranked Using the AHRM | Initial ranking, three values unknown. | Bruce Wanstall |
7/24/2003 | Cleanup Level(s) Approved | Method 2 migration to groundwater | Bill Janes |
7/24/2003 | Cleanup Plan Approved | Biocell design was included in the final cleanup report for the site and approved for construction. | Bill Janes |
7/24/2003 | Long Term Monitoring Established | Four biocells to undergo periodic sampling until it is determined that cleanup levels have been met. | Bill Janes |
7/24/2003 | Update or Other Action | Letter sent to RP stating cleanup complete but final closure will not occur until biocell soils meet cleanup level. Deminimis amount ot contamination above cleanup levels (estimated less than 2 cy) remains along the Cathedral Way property line. | Bill Janes |
2/4/2004 | Site Ranked Using the AHRM | Surface water use and index updated. | Bill Janes |
2/4/2004 | Update or Other Action | Per SE Mgmt Services email, this past fall TM Construction completed the screening of all of the material and set up the first of the 30'x100' bioremediation cells. The remaining 3 cells were set up and completed last month. Fertilizer has been added to all 4 cells, and the cells will remain covered until spring. | Bill Janes |
2/27/2004 | GIS Position Updated | Updated lat/long data using GPS readings from Bill Janes 2/13/04 field trip. | Cliff Walden |
7/5/2005 | Update or Other Action | Verbal report from Tom Hanna regarding June 3, 2005 soil stockpile sampling. Two cells have reached cleanup levels; two still need additional work. | Bill Janes |
8/9/2005 | Update or Other Action | Biocells report received. Biocells 1and 4 can be closed based on a 95% UCL of the mean. Biocell 4 95% UCL of 252 mg/kg DRO is slightly above the cleanup level but this level is insignificant when considering sampling variability. Biocell 2 95% UCL is at 336 mg/kg DRO; biocell 3 95% UCL isl at 859 mg/kg DRO. Treatment at these two cells will be continued through the fall with confirmation sampling to occur just before winter. | Bill Janes |
1/13/2006 | Update or Other Action | Telecon with Tom Hanna - Remaining two biocells will not be sampled until spring. | Bill Janes |
7/27/2006 | Update or Other Action | Email from Tom Hanna. Shee Atika had the soil in the two Charcoal Island biocells turned over earlier this year, but Bob Loiselle has indicated that he would like to have the soil turned over once more before sampling takes place. Final soil tilling and sampling will probably take place sometime in August | Bill Janes |
10/6/2006 | Update or Other Action | Biocells 2 and 3 sampled this date. | Bill Janes |
11/13/2006 | Update or Other Action | Charcoal Island Bioremediation Summary Report received. Biocell # 2 - 95% UCL for DRO 220 mg/kg and for RRO 133 mg/kg. Biocell # 3 - 95% UCL for DRO 374 mg/kg and for RRO 143 mg/kg. Some issues with the data package need to be resolved. | Bill Janes |
12/12/2006 | Update or Other Action | Lab QA checklist completed this date in-house. Email communication sent to Tom Hanna regarding questions with data pakage. | Bill Janes |
2/15/2007 | Update or Other Action | Correspondence received from Tom Hanna resolving questions with Charcoal Island biocell sampling data package. | Bill Janes |
3/20/2007 | Update or Other Action | Final site closure and biocell closeout approval - Biocells 1 and 2, totaling about 185 cy, have met closure levels and will be left at their original Charcoal Island treatment location. Soil from biocells 3 and 4 are slightly above migration to gw cleanup levels still. This soil, totaling about 185 cy, will be moved approximately 1,000 feet to the northeast and placed behind the 601 ALP builiding. It will be spread in a 6-9 inch layer and seeded with grass. No further testing is required as the average DRO concentration is expected to meet the migration to gw cleanup level once this is done. | Bill Janes |
3/20/2007 | Long Term Monitoring Complete | Administrative action on 5/1/2013. | Kristin Thompson |
3/20/2007 | Site Closure Approved | Closure action added 11/3/15 during data quality review | Mitzi Read |
5/16/2007 | Update or Other Action | Modification to biocell closure plan. approved All biocell soils to be spread on-site and seeded versus removing part of the material to a new location. | Bill Janes |
