Site Characterization Report Approved |
Four soil samples were collected on 4/27/06 and delivered to the lab by the PERP the same day for laboratory analysis. Three samples were analyzed for DRO using method AK Method 102, and one for GRO, and benzene, toluene, ethylbenzene, and xylenes (BTEX) using AK Method 101 & 8021B. Samples were collected from depths ranging from 10" to 18" bgs. Laboratory results for DRO ranged from 2,680 mg/kg to 6,780 mg/kg. GRO was 6,100 mg/kg. Total BTEX was 1.9598 mg/kg with benzene at 0.0128 mg/kg, toluene at 0.212 mg/kg, ethylbenzene at 0.220 mg/kg, and total xylenes at 1.515 mg/kg. The sample results indicate that further cleanup work needs to occur for this spill. Sent a letter this date requesting more a corrective action plan for ADEC review prior to any further cleanup work and that you retain a qualified impartial third party to assist you with the remainder of the cleanup operations per 18 AAC 75.355. Please be aware that cleanup work taking place within the State right-of-way may need to be permitted by the Alaska Department of Transportation. |

Update or Other Action |
Received a letter with this date from Randy Elliott who was asked by job superintendent Mervyn Gilbertson of Big States Logistics to contact the ADEC regarding a spill remediation being conducted at mile 83 of the Richardson Highway south of Glennallen. After visiting the site, Mr. Elliott decided to construct a lagoon on his property at Kenny Lake (mile 10.2 Edgerton cutoff) to finish the processing of the contaminated soil. There are 280 c.y. of soil involved which contains #2 diesel fuel. This material will be dried using mechanical agitation and covered whenever weather prohibits evaporation e.g. rain or snow conditions. Mr. Elliott is aware that this process may take as long as five years and he is prepared to be responsible for at least that length of time or until the soils are dried fully. Once it is in his possession, he will accept liability for its disposal according to ADEC direction.
There are no documented wells in the subdivision in which Mr. Elliott lives due to water depths in excess of 500 feet. |

Spill Transferred from Prevention Preparedness and Response Program |
After review of the Alaska Resources & Environmental Services, LLC (ARES) “Big State Logistics Phase II ESA & Site Characterization Report, Mile 83.5 Richardson Highway, Alaska” dated January 2007, a letter was sent out this date indicating that effective 4/9/07 this site sould be transferred to the CSP for management. Site transferred by PERP staff Eric Henry. Spill no. 06229905801; spill date = 2/27/06; substance = diesel; quantity = unknown.
Approximately 115 cubic yards of contaminated soil were excavated during the ARES Phase II ESA on July 14 & 15, 2006. Randy Elliot, a third party landowner in the area, agreed to accept the soil knowing it was contaminated. He has constructed an area on his property located at milepost 10.2 of the Edgerton Highway where the soil is spread. ADEC had no objections to Mr. Elliott receiving the contaminated soil provided the location of the land farm was not a threat to human health or to the environment and that the soil would be tilled at least annually. At which time field screening would take place and analytical samples collected to verify the success of the treatment method. Information provided to ADEC by Mr. Elliot about the location of the land farm and its proximity to potential receptors was sufficient to assure the proposed soil treatment method would not pose a threat to human health or the environment.
Due to the contaminated soil remaining at the spill site surrounding the fiber optic cable and the contaminated soil generated during the execution of the Phase II ESA that is being land farmed at Mr. Elliott's property, regulatory management of this site will require an institutional control to record the location and amount of contaminated soil remaining at the site; therefore, this site is transferred from the ADEC Prevention & Emergency Response Program to the ADEC Contaminated Sites Program - effective April 9, 2007. |

Site Characterization Report Approved |
Reviewed the Alaska Resources & Environmental Services, LLC (ARES) “Big State Logistics Phase II ESA & Site Characterization Report, Mile 83.5 Richardson Highway, Alaska” dated January 2007. A utility locate at the site was conducted by GCI personnel and determined that a fiber optic cable was located within the central portion of the spill area at approximately 4-5' bgs. Due to removal limitations in the vicinity of the fiber optic cable (no mechanized digging within 2' of buried cable), ARES obtained verbal approval from ADEC to leave petroleum contaminated soils in place 2 feet either side of the cable.
Sixty-eight field screen soil samples were collected and analyzed on June 14-15, 2006. Soils encountered during excavation and collection of soil samples consisted primarily of dark brown silt and silty gravels. An organic mat ranging from 4-6 inches was observed during excavation activities. Petroleum contaminated soils were removed until cleanup objectives were met based on field screen results. The total area of excavation was approximately 443 square feet and soils were removed to a maximum depth of 10' bgs. Approximately 115 cubic yards of petroleum contaminated soils were removed during excavation. Site restoration included backfilling with clean pit run gravel and leveling backfill material to grade.
Petroleum contaminated soils were transported to the property of Mr. Randy Elliot for landfarming of petroleum contaminated soils. Mr. Elliot is located at milepost 10.2 on the Edgerton Highway. Soils were placed in a secure area, on a bermed pit liner in accordance with ADEC regulations. Fertilizer was added to aid in bio-remediation and enhance microbe growth and lime added to adjust soil for proper pH. The soil was then covered with visquene.
Seven soil samples were collected on June 15, 2006 from the area of excavation. Samples were grab samples and were analyzed for DRO and BTEX. Samples were collected generally from a depth of 5-10 feet bgs. Final confirmation soil samples were collected from sidewalls, end walls and the bottom of the excavation pit in order to delineate the lateral and vertical extent of contamination and to verify site conditions following removal of contaminated soils. Excavation was forced to terminate within 2' either side of the GCI fiber optic cable upon discovery of buried cable. Field screen samples indicated that levels exceeding contaminated soil cutoff levels (> 25 ppm) remained in place surrounding the GCI fiber optic cable. Target cleanup level for the petroleum-contaminated spill site was determined to the default 18 AAC 75.341 Method Two cleanup levels.
As confirmed by laboratory samples, soil levels for DRO and BTEX were non-detect for the sidewalls, endwalls and bottom of the excavation pit except for the immediate area surrounding the GCI fiber optic cable. These analytical results were DRO at 1,580 mg/kg and ethylbenzene at 7.51 mg/kg in Sample BSL6 at 5.0 feet bgs. All practical quantitation limits (PQL) for ND analytical results were below the cleanup levels. Total removal of petroleum contaminated soils was not possible due to presence of the fiber optic cable. Due to excavation restrictions, it is estimated that 15-25 cubic yards of contaminated soils remain in place.
ARES recommended that landfarmed soils should be turned in summer of 2007 to aid in aeration. In addition, field screen samples should be collected in order to monitor cleanup progress. The process should be repeated on an annual basis until field screen samples results indicate that levels of hydrocarbons are <25 ppm. Final confirmation samples would then need to be collected (stockpiled soil and underneath pit liner) in accordance with ADEC regulations. Lab results should then be submitted to ADEC for final site closure. In the event that maintenance activities would need to be conducted in the future on the fiber optic cable, GCI Inc. should be notified that any disturbance to the soil within the spill site be tested for DRO and BTEX compounds prior to dispersal of soils to the surrounding ground.
The depth to groundwater at the site is unknown and is expected to be greater than 50 feet bgs. |

On this day, the ADEC received the Contaminated Soil Stockpile Report, dated January 2014. The report documented soil screening and sampling activities for the soil land-farm located at Mile 10.2 Richardson Highway. According to the report, the landfarm was constructed on June 15, 2006 with 18 inch high soil berms and was lined with polyethylene plastic sheeting prior to placing any soils in the land-farm. Once the soils were placed, the land-farm was measured to be roughly 24 feet wide, 100 feet long, and 3-3.5 feet high. The volume of contaminated soil contained in the land-farm was estimated at 250 cubic yards. The report indicated that no soil tilling or aerating had taken place since the original construction date and the land-farm remains uncovered. On October 31, 2011, ARES personnel collected 20 soil samples from the land-farm at depths ranging between 18 and 30 inches bgs. All of the soil samples were field screened utilizing a PID for the presence of VOCs. Based on field screening results, six confirmation soil samples, including a duplicate soil sample, were collected from the land-farm and were submitted for analysis of DRO and BTEX. Analytical results indicated that DRO, ethylbenzene, toluene, and xylenes were present in the soils below ADEC cleanup criteria. Benzene was not detected above the laboratory method reporting limit (MRL) in any samples; however, the MRL for benzene (up to 0.0400 mg/kg) was identified above the ADEC cleanup level of 0.025 mg/kg in three of the soil samples. On August 10, 2013, ARES staff returned to the site and collected an additional 20 field screening samples and 2 analytical soil samples using the same procedures as described above. These soil samples were only analyzed for polynuclear aromatic hydrocarbons (PAHs). None of the samples collected from 2013 exhibited any PAHs above the ADEC cleanup criteria. |
