We make every effort to ensure the data presented here is accurate based on the best available information currently on file with DEC. It is therefore subject to change as new information becomes available. We recommend contacting the assigned project staff prior to making decisions based on this information.
Problems/Comments
The release site is within a controlled access facility fenced to preclude public access. Workers frequenting the site are trained and prepared for hazardous conditions and potential exposure risk. Groundwater and surface water in the area, if present, have neither sufficient quantity nor quality to be used as a drinking water source. Soil samples were collected from bare soil near the storage shed for hazardous materials. Laboratory results for this sample (KS-4) had a DRO concentration of 609 milligrams per kilogram (mg/kg) and an RRO concentration of 5930 mg/kg. Sample KS-4 required a dilution in order to quantify the RRO. DEC visited the Site in March with R&M Engineering-Ketchikan. R&M collected samples at the hazmat shed and found no DRO or RRO in the sample.

| 3/24/2016 | Site Visit | DEC met with Airport Manager Mike Carney and R&M Engineering Robert Badgett at the Ketchikan International Airport to perform site investigation sampling at the airport rescue and fire fighting building (ARFF) HazMat Shed Site and the paint debris stockpile Site. Later DEC met with Robert Badgett at the R&M office to resolve technical issues with the laboratory report for previous samples collected at the ARFF Bldg. | Bruce Wanstall |
| 7/13/2016 | Document, Report, or Work plan Review - other | DEC approved Ketchikan Airport ARFF Closure Report by R&M Engineering-Ketchikan Inc. R&M completed the report on sampling at the site during the March 2016 site visit. The Report concludes that confirmation soil sample results indicate no measureable release has occurred at the site and recommends the KS-4 site be closed. DEC concurs with the Report conclusions and recommendations without comment. | Bruce Wanstall |
| 7/29/2016 | Exposure Tracking Model Ranking | A new updated ranking with ETM has been completed for source area 79886 HazMat Shed. | Bruce Wanstall |
| 9/22/2016 | Cleanup Complete Determination Issued | Based on the information provided to date, DEC has been determined that the contaminant concentrations remaining on site do not pose an unacceptable risk to human health or the environment and no further remedial action will be required unless new information becomes available that indicates residual contaminants may pose an unacceptable risk. | Bruce Wanstall |
