Problems/Comments
The Kokamiut Corporation operated this AST farm for the storage, supply and dispensing of gasoline and fuel oil to its village customers. These operations have since been moved to the new consolidated bulk fuel facility in Akiak. In 1999, the former AST farm was located approximately 30 feet from the Kuskokwim River and approximately 100 feet from a private well. The Kuskokwim River bank is rapidly eroding and will eventually overtake this AST farm. The two existing ASTs, which are believed to be empty, are within a lined 2-foot-high dirt and gravel dike. The liner is torn and misplaced throughout the AST farm. Petroleum odor and stained soil was noted around the fuel dispensing pumps. There is no fence around this facility. The AST farm consists of two vertical, welded steel, single wall tanks; both have the capacity of approximately 24,000 gallons. The ASTs sit on 12-by 12-inch timbers with 4-by-12-inch planking within the diked area. The former third tank that existed at this tank farm was a 10,000-gallon, horizontal, welded steel, single wall integral diked tank mounted on steel skids sitting directly on a grade south of the existing berm. The AST formerly stored gasoline. The one soil sample that was collected at 16 inches bgs was non-detect for any contaminants, however a PID reading taken at the south east side of the fuel dispensing station, 15 to 17 inches bgs, adjacent to the gasoline pump, was 1,240 ppm. A picture of the tank farm area taken by ADEC in August 2008 indicates the riverbank is rapidly eroding. It appears the tank farm, which was located 30 feet from the Kuskokwim River in 1999, is now located approximately 20 feet from the River due to erosion. The tanks were removed from the site in 2009. Pictures taken by Solid Waste In October 2012 indicate the former tank farm footprint has eroded into the Kuskokwim River. Therefore, the site status has been updated from active to informational.

| 4/16/2003 | Site Added to Database | Possible DRO and GRO contamination. | Deborah Williams |
| 4/16/2003 | Site Ranked Using the AHRM | Preliminary ranking. | Deborah Williams |

| 8/1/2008 | Update or Other Action | A picture of the tank farm area taken by Doug Huntman from the Solid Waste Program, in August 2008, indicates the riverbank is rapidly eroding. It is estimated that the tank farm, which was located 30 feet from the Kuskokwim River in 1999, is now located approximately 20 feet from the River due to erosion. | Grant Lidren |
| 12/2/2008 | Exposure Tracking Model Ranking | Initial ranking with ETM completed for source area id: 74344 name: former ASTs | Grant Lidren |
| 1/22/2009 | Update or Other Action | An ADEC telephone conversation with Kokarmuit Corp., indicates the Kuskokwim River is rapidly eroding and the tanks, which are approximately 20 ft. away, could potentially be overtaken by the River in the fall of 2009. | Grant Lidren |
| 1/27/2009 | Update or Other Action | As per the ADEC PM, the following is reported in the the most recent site reconnaissance report dated December 2000. The section titled, “ Old Corporation Tank Farm” pages 7-9, pertains to the contaminated site of interest (Akiak Kokarmuit corporation TF file # 2402.38.004). In summary the report states that in 1999, the former AST farm, which consists of two vertical ASTs, was located approximately 30 feet from the Kuskokwim River. During the site visit, petroleum odor and stained soil was noted around the fuel dispensing pumps near the tanks. The one soil sample that was collected at 16 inches bgs was non-detect for any contaminants, however a PID reading collected at 17 inches bgs, adjacent to the gasoline pump, was 1,240 ppm. It appears there is no analytical sampling data that confirms contamination above ADEC CU levels. | Linda Nuechterlein |
| 1/28/2009 | Update or Other Action | Follow-up with John Brown/PERP concerning the eroding Akiak Tank Farm. He said that PERP would write a letter to the village requiring them to first clean the tanks (due to sludge), and then move them away from the river. John Brown requested additional information from the CS file which was supplied by Grant Lidren (PM) so that he (John Brown) could follow-up with Gary Folley/Soldotna. This site is in Gary’s management area and it sounded like he may get Bob Carlson/PERP in Bethel involved also. | Linda Nuechterlein |
| 3/9/2009 | Update or Other Action | PERP sent a letter on March 5th to the Kokarmuit Corp. requesting the removal of the TF | Grant Lidren |
| 9/28/2009 | Site Visit | A site visit, performed by SLR, was completed on September 28 & 29 2009. The tanks have been removed. The damaged liner from the former TF is still present and sheen was noted within the diked area. The community is concerned this area will erode into the Kuskokwim River. Furthermore, it was reported that the Army Corp of Engineers considers Akiak to be greatly affected by future flooding and erosion events. | Grant Lidren |
| 12/8/2011 | Potentially Responsible Party/State Interest Letter | PRP letter sent to the Kokarmiut Corp. on this date. | Grant Lidren |
| 1/20/2012 | Update or Other Action | ADEC received phone call from Kokarmiut Corp. on this date. They plan on having meeting with City to discuss contaminated sites. | Grant Lidren |
| 10/10/2012 | Update or Other Action | Pictures taken by Solid Waste In October 2012 indicate the former tank farm footprint has eroded into the Kuskokwim River. Therefore, the site status has been updated from active to informational. | Grant Lidren |
| 5/10/2013 | Site Visit | The Solid Waste Program performed a site visit during the week of May 6th. Residents indicate the location of this old tank farm has since eroded into the river. | Grant Lidren |
