Problems/Comments

The facilities at the Point Carrew Garrison (AOC C) were built for support of W.W.II military presence in Yakutat between 1940 and 1946. These facilities included an ammunition storage facility, a 155mm rigid-mount gun emplacement and housing, a CA Garrison, warehouses, a small dock on the Ankau Inlet, a plotting room, powerhouses, a pump house, quarters buildings, a mess hall, a post exchange, a motor shed, and a garbage dump. The Ankau area was used to support the gun stations along the west and south coast of Yakutat. The field notes from the USACE 1984 cleanup indicated that most of the materials and building ruins from the area were loaded into trucks and hauled to the city solid waste dump. Some of the materials and structures may still be present. There are seven sites that have been investigated within AOC C; Ankau Bridge Area Garbage / Drum Dump (AOC C1), Point Carrew Garrison Drum Dump (AOC C2), Garrison Area Powerhouse Foundation 1 (AOC C3), Garrison Area Surface Debris (AOC C4), Ocean Cape Powerhouse No. 1092 (AOC C5), 50,000-Gallon Fuel Tank (AOC C6), and Ankau Slough Powerhouse No. 1093 (AOC C7).

4/28/2003	Site Characterization Report Approved	Point Carrew was investigated over two field seasons. In 2000 the dump area was investigated to delineate the extent of buried debris in the drum dump and surface debris areas. DRO was documented in three surface soil samples, two soil boring samples and in the sediment sample. DRO was detected in the groundwater below Table C levels. Silver was reported in one surface soil sample above Method II. Chromium was reported above background levels no PCBs were found. In 2001 Powerhouse 1092, 1093 and a former 50,000 gallon wood stave diesel tank were investigated. The location of powerhouse 1092 could not be found. DRO was detected up to 5800 mg/kg in soil at the tank, and 6.84 mg/l in groundwater. Powerhouse 1093 was identified by the presence of a 12 foot x 18 foot concrete foundation. No evidence of PCBs was found, low levels (below Method II) of fuel were detected. Arsenic and chromium in soil were above background in soil. Lead, arsenic and chromium were in groundwater above Table C.	Debra Caillouet

9/30/2009	Update or Other Action	ADEC staff signed a CON/HTRW project closeout report fort he Formerly Used Defense Sites associated with the Yakutat Air Base. The State of Alaska, through the Department of Environmental Conservation concurs with this USACE project closure. The decision may be reviewed or modified in the future if information becomes available that indicates the presence oif military CON/HTRW that may cause unacceptable risk to human health or the environment. The remeduiation of these sites will continue as necessary, this report only states that no containerized wastes are known to be present at the subject sites.	Jonathan Schick

Surface soil samples were collected at the location of the historical exceedances for chromium. The samples were analyzed for hexavalent chromium, and hexavalent chromium was not detected. Because the chromium at AOCs C1 and C2/C4 was determined not to be hexavalent chromium, the chromium concentrations at the site are below the applicable ADEC cleanup levels.	Jonathan Schick
5/30/2014	Site Characterization Workplan Approved	The ADEC Contaminated Site Program approved the 2014 Supplemental Remedial Investigation Work Plan. The objectives of the investigation at AOC C2, C3, C4 were to 1) determine risk posed groundwater and soil contamination using the ADEC Method Three Calculator and the Hydrocarbon Risk Calculator; 2) determine the type of debris and source material in the dump using test pits; 3) determine the current groundwater condition; 4) determine whether PCB contamination is present in the surface water and sediment.
