4/15/2008 Site Characterization Report Approved The report does provide additional characterization data for the Tununak FSA and is approved under 18 AAC 75.335. As explained in the comments on the draft of this report, the samples analyzed for total organic carbon are not representative of the soil where the contamination was detected. To be able to calculate an alternative cleanup level (ACL), the soil properties must be determined in an uncontaminated area that has similar soil properties. DEC can not approve an ACL based on this data. Debra Caillouet

5/3/2013 Site Characterization Report Approved Final Toksook Bay Federal Scout Readiness Center, Data Gap Investigation Report, April 2013 The report recommends alternative soil cleanup levels based on the aliphatic/aromatic split determined by the Washington EPH/VPH methods. The total DRO based on this is 10,962 mg/kg for the main source area and 10,621 mg/kg for the 2011 source area. These values are calculated from the ingestion cleanup levels of 4100 mg/kg DRO aromatic and 10,000 mg/kg DRO aliphatic. ADEC has no objection to the use of these cleanup levels. Confirmation sampling will be necessary to show all three levels,(total DRO by AK102, DRO Aromatic and DRO Aliphatic) are met for each site. Debra Caillouet
6/4/2013 Cleanup Level(s) Approved DRO Aliphatic 10,000 mg/kg, DRO Aromatic 4100 mg/kg, DRO AK102 10,962 mg/kg Debra Caillouet
