Problems/Comments

On November 9, 2015, soil samples were collected from an area where illicit dumping is believed to have occurred. The dump site is located in a low-lying marshy area and appears to be a wetland, although not mapped by the National Wetlands Inventory. A sampling grid was established in the low-lying area and field-screening samples were collected from the center of each grid. The soil samples were field-screened using heated headspace methodology with a Mini Rae 3000 Photoionization Detector (PID). One sample destined for laboratory analysis was collected from the location of highest field screening result (15-LRID7-10). Because of the high percentage of organic material observed at the dump site, a background sample was collected from roughly 30 feet west of the sampling grid (15-LRID11-12) to determine if organics would bias results. An additional sample was also collected from the east end of a gravel pullout located at the end of Eldorado Drive (15-LRID12-6); where a stockpile of unknown origin was observed but has since been removed. Analytical samples were submitted for laboratory analysis of gasoline range organics, diesel range organics (DRO), residual range organics, volatile organic compounds, polycyclic aromatic hydrocarbons, and Toxicity Characteristic Leaching Procedure metals. Samples 15-LRID7-10 and 15-LRID12-6 exhibited concentrations of DRO at 500 mg/kg and 1060 mg/kg, respectively; both of which exceed the migration-to-groundwater cleanup level of 250 mg/kg for DRO. The background sample (15-LRID11-12) exhibited a concentration of DRO at 45.3 mg/kg, which could be biased by the percentage of organic material characteristic of some hydric soils. The origin of dumped soils is reportedly from a diesel pickup truck that was being staged at 4621 East Palmer-Wasilla Highway. The originating release is being managed under a separate record, see Hazard ID 26478, file number 2265.38.041.

7/14/2020 Workplan Requested A letter was sent following the June 16th ADEC letter requesting a work plan (by July 13) and the June 22 phone call with the RP. This letter documented the June 22 phone call and requested follow up and a work plan immediately. Lisa Krebs-Barsis
10/7/2022 Site Visit CSP personnel Naomi Mason and Alena Voigt conducted a site visit and met with Mr. Huber. Mr. Huber identified where the dumping occurred. The area had grown over with vegetation. CSP dug shallow test pits in the area and conducted warm water sheen field screening and headspace field screening. No sheen was observed during the warm water sheen screening and the maximum PID reading was 4.6 ppm. No visual or olfactory signs of contamination were observed. Lisa Krebs-Barsis
12/13/2022 Workplan Requested A letter was sent by the department requesting a work plan by January 31, 2023. The letter identified the steps toward compliance. Lisa Krebs-Barsis
12/16/2022 Enforcement Action On December 2, the responsible party informed the department that he had conducted a removal action on the property and disposed of the excavated material at a landfill. The work and transport was not done with approval by the department and a Notice of Violation was sent on December 16, 2023. Lisa Krebs-Barsis
5/8/2023 Compliance Advisory Letter A compliance advisory was sent noting that the responsible party had not provided a work plan by the most recently requested date of January 31 and described the outstanding cost recovery for department oversight. Lisa Krebs-Barsis
6/21/2023 Document, Report, or Work plan Review - other A workplan to collect soil samples was submitted by the responsible party's consultant. Comments were sent. Lisa Krebs-Barsis
6/22/2023 Site Characterization Workplan Approved A work plan to collect confirmation soil samples was approved. The responsible party obtained right of entry for his consultant on both properties. Lisa Krebs-Barsis
6/23/2023 Site Visit CSP personnel Naomi Mason and Alena Voigt conducted a site visit to observe soil sampling conducted by the responsible party's consultant. Lisa Krebs-Barsis
1/3/2024 Site Characterization Report Approved A site characterization report was approved. In June 2023 screening and sampling was done in the area at the base of the slope where soil had been removed without coordination in October 2022 by the RP. Three samples were collected and a duplicate and were analyzed for PAH and DRO. DRO was detected but all results were well below the most stringent cleanup levels. Lisa Krebs-Barsis
4/3/2024 Exposure Tracking Model Ranking A new updated ranking with ETM has been completed for source area 79842 Illegal Dumping of Petroleum Contaminated Soil. Lisa Krebs-Barsis
6/28/2024 Cleanup Complete Determination Issued Based on a review of the environmental record, analytical results indicate detectable concentrations for Diesel Range Organics (DRO) remain in the soil at concentrations between 26.4 mg/kg and 36.3 mg/kg. These results are below ADEC Method Two Soil Cleanup Levels in 18 AAC 75.341 Tables B1 and B2 and ADEC has determined that residual contaminant concentrations meet the human health cumulative risk criteria for residential land use.
