2/6/2001 Update or Other Action Met with RPCON (John Janssen) to discuss proposal for FAP work plan. Agreed to conduct additional SA to delineate the extent of impact, and then determine if corrective action is necessary. It may be appropriate to leave in place without removal. Future work will likely be funded on a future grant. John Carnahan
11/19/2001 Release Investigation Release Investigation submitted by Oasis. Maximum allowable levels exceeded for GRO in soil at 10 and 25 feet depths. Permafrost found at 20 to 30 feet depth throughout site. Water sample from on-site drinking water well; two PAHs were detected below cleanup levels and were attributed to plastic piping in the water system. Janice Wiegers
2/22/2002 Leaking Underground Storage Tank Corrective Action Underway Approved SVE alternative in 2002 FAP grant application. SVE system will treat soil contamination to 15 foot depth with ingestion and inhalation target cleanup levels. Janice Wiegers

6/9/2004 Update or Other Action Final excavation and closure sampling report submitted. Three confirmation soil borings were installed in April. Based on soil sampling results, 138 tons of contaminated soil were excavated from the west side of the Denali RV Park office building. Limited contamination remained at the south side of the excavation where utility lines prevented further soil removal. Contamination also remains below 15 feet. The SVE system was decommissioned in May during the excavation work. Janice Wiegers
7/21/2004 Institutional Control Record Established Deed notice recorded in the Nenana Recording District. Limited soil contamination containing concentrations above ingestion/inhalation cleanup levels may remain between 8 and 23 feet. ADEC notification is required if contamination is exposed or becomes accessible. Janice Wiegers
5/13/2005 Conditional Closure Approved NFRAP letter sent to Wendel Neff. Limited residual contamination above the Alternative Cleanup Levels remain above 15 feet. Untreated contamination is also present above the permafrost which is located at approximately 25 feet, but this contamination is not expected to migrate to groundwater. Janice Wiegers
5/13/2005 Update or Other Action Environmental Health contacted about 2001 drinking water results. Contaminated Sites recommended periodic monitoring of the public drinking water well for petroleum contaminants. Janice Wiegers
7/13/2005 Update or Other Action Coordinated with the ADEC Drinking Water Program concerning Class B Public Well and Denali RV Park. Drinking water required sampling for VOCs. No VOCs were detected in drinking water. Sent letter to Ken Engles at Denali RV Park stating that these analyses would not longer be required but periodic testing for petroleum compounds are still recommended. Janice Wiegers
12/20/2011 Update or Other Action Site management staff changed to IC Unit. Evonne Reese
12/20/2011 Institutional Control Compliance Review IC review conducted. Evonne Reese
11/1/2012 Institutional Control Update Groundwater use restriction IC requirement removed due to 2005 testing that found VOCs were non-detect in the drinking water well onsite. Evonne Reese
6/12/2015 Institutional Control Compliance Review Schedule to send an IC reminder letter to the Denali RV Park & Motel. Evonne Reese
6/22/2015 Institutional Control Update An IC reminder letter was issued to the responsible party on this date. Kristin Thompson
4/4/2017 Institutional Control Update An IC detail was placed on this site record that had been omitted in error. A note was added in the IC requirements that even though there is no need to continue sampling groundwater, DEC should be coordinated with before installing new wells due to the potential of drilling through contamination which could be carried to the groundwater. Evonne Reese
4/12/2017 Institutional Control Compliance Review IC compliance review conducted. Closure/ID Details updated. An ICs verification letter was issued. Reminder system set for follow-ups to occur every three years. Kristin Thompson
5/1/2017 Institutional Control Periodic Reporting Received a call from the landowner providing their email address for future electronic correspondence. Kristin Thompson
