Problems/Comments
On 10/15/90, ADEC was informed that a diesel spill from the fuel tank of a piece of heavy equipment contaminated approximately 400 pounds of soil at the Hughes airport. All contaminated gravels were removed promptly, ADEC approved plans for landfarming of the contaminated soils. No further treatment of the soil was reported to the ADEC. In 2005, the Alaska Department of Transportation and Public Facilities (ADOT&PF) provided additional information that identified the location of the area formerly leased by Central Alaska Gold Company at the Hughes Airport. The site is approximately ¼ mile from the village of Hughes and down gradient from the village’s drinking water source. In 2006, ADEC staff visited Hughes in response to extreme flooding of the Koyukuk River and saw no evidence of a soil stockpile and it appeared the subject soil was either graded into the landing strip or washed away during the flood. Site transferred from PERP. Need to affirm that land is owned by state. (rpltr) Last staff assigned was Basketfield.

| 8/17/2006 | Record of Decision | Shannon Oelkers | |
| 8/18/2006 | Site Closure Approved | The site is a commercial/industrial facility located at the Hughes Airport. It was used for storage and maintenance of equipment by the Central Alaska Gold Company but is currently vacant. It is expected to be used for commercial/industrial airport purposes in the future. The removal of contaminated soil and subsequent stockpiling of the contaminated soil at the Hughes Airport site has removed the source(s) of contamination and the majority of soil impacted from the small diesel spill. Based on the information provided to date, ADEC has determined that the amount of contamination was minor in extent and was removed to the extent practicable. As a result, site closure is approved for this property. | Shannon Oelkers |
