(Old R:Base Action Code = SA1A - Phase I Site Assessment Approval). Draft Report for Preliminary Assessment/Site Investigation dated February 1997 reviewed (received 12/12/97, prepared by Ogden Environmental and Energy Services). GRO detected in 3 of 5 soil samples ranging from 210 to 500 mg/kg; DRO in 6 or 7 samples ranging from 99 to 150,000 mg/kg; benzene in 1 of 4 samples at 1.5 mg/kg; TPH in 6 or 7 samples from 360 to 204,000 mg/kg. Matrix score indicates Level B cleanup standard. |

Update or Other Action |
A Site Assessment was done by Portage Environmental under NALEMP. The conclusion is that the DoD and AKARNG are not responsible for the contamination and therefore the site is not eligable for further work under NALEMP. Site is reported to be the Old BIA school and the contamination related to the BIA activities. Report is of a 1997 assessment. |

Draft Tuntutuliak Federal Scout Readiness Center, Data Gap Investigation Report, March 2013
Similar to other recent DGI reports, this one also does not include all supporting data, misapplies the EPH/VPH from multiple source areas and duplicates. This one even creates a relatively high cumulative risk from all non-detected results.
Please have this report reviewed by the contractor and resubmitted with all data and the appropriate use of the data.

Site Characterization Report Approved |
Final Tuntutuliak 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 11,482 mg/kg for the main source area and 11,147 mg/kg for the generator 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.

Sent approval letter and minor comments for draft Remedial Action Report. The draft report documented excavation activities at the site in preparation for site closure without ICs. 36 yd3 was excavated from three source areas and shipped in SuperSacks to an appropriate landfill for disposal. Soils in the area are characteristic of tundra and have high organic matter (peat) content and low solid content (as low as 13%) especially for the surface layer (up to two feet below ground surface). The laboratory data reflected these characteristics and diesel range (DRO) and residual range (RRO) organics analyses were run both with and without silica gel cleanup. These analyses demonstrated that the peat in the soil co-elutes with DRO and RRO and results in higher petroleum values than are actually present. The chromatograms and chemist’s comments verify these conclusions. Therefore, the ADEC concurs that naturally-occurring organic material is quantified erroneously as RRO at concentrations exceeding site-specific cleanup levels in several samples at the site. Aside from these erroneous values, all of the confirmation samples collected post-excavation have concentrations lower than the site-specific cleanup levels, and the ADEC anticipates issuing a Cleanup Complete without ICs designation once a finalized copy of the report is received by our office. |
