Offsite Soil or Groundwater Disposal Approved |
In response to review of the Shannon & Wilson "Request to Transport and Treat Impacted Soil and Groundwater, Big Su Lodge, Mile 104 Parks Highway, Talkeetna, Alaska" dated 9/18/09, to facilitate the request in absence of the regular project manager, approval to transport and remediate impacted soil and groundwater generated during release investigation activities at the above site was granted this date.
The impacted media consists of drill cuttings and development water from Boring BIIMWI. The media is contained in 55-gallon drums and will be transported and treated by Emerald Alaska.
The ADEC indicated approval for transportation and treatment of the impacted media
by signing the line at the bottom of this letter and returned a copy to Shannon & Wilson.
This approval applies only to the HOT portion of the site. |

Reviewed the S&W "Release Investigation; Big Su Lodge, Mile 104 Parks Highway; Talkeetna, Alaska" dated September 2009. Between 6/8-11/09, the project consisted of collecting near-surface and subsurface soil samples, advancing soil borings, installing MWs in the borings, measuring depth to water and collecting GW samples from each MW, and surveying. Soil samples were screened for VOCs using a PID. The near-surface soil was evaluated for the magnitude and extent of contamination based on grid laid out on 5’ centers and samples were collected for field screening and visual classification from each square at depths between 0.5 and 1’ bgs using hand shovels. Grid locations with the higher field screening readings generally corresponded to topographic low areas. 7 samples, including one duplicate sample, were selected for analytical testing based on field screening results and/or sample locations.
4 soil borings were advanced to evaluate the nature and extent of soil and GW contamination at the site. Boring B1 was positioned at the source area, the former AST HOT, and two were advanced south and down gradient of the source area with respect to the GW flow direction. Boring B1 had to be relocated about 6‘ south of the initial location for completion after auger refusal occurred at 13.2’ bgs where soil sampling was completed and a monitoring well installed. GW was encountered between about 9.8 and 11.5’ bgs during drilling. Soil samples were collected from each borehole generally at 2.5’ intervals.
Borings B1 through B4 were completed as monitoring wells MW1 through MW4, respectively, and developed on 6/10-11/09. MW1 was installed ~20' mostly cross-gradient from the AST site. The screened intervals of the wells were approximately centered on the GW contact depths at time of drilling. A closed-loop elevation survey of the top of the MW casings was conducted and water depth relative to the top of the well casings was measured on 6/11/09 and varied between about 8.8 and 11‘ bgs. This information was used to develop GW elevation contours that indicated that GW flowed south at that time at a gradient of about 0.03 foot per foot.
The on-site public drinking water well is ~25' from the former AST location and oriented at ~45 degrees down gradient of it.
The decontamination water from Borings B1 and B3 was discharged on the ground at the AST release area. The decontamination water from Boring B4 was added to the 55-gallon drum containing development water from Well MW1. The drill cuttings from Boring B1, decontamination water, and development water from MW1 were reportedly disposed at an off-site facility. The soil and water associated with the remaining borings and wells may be land spread and discharged at the site in a non-environmentally sensitive area.
7 soil samples, including one duplicate were taken from between 0.7 and 0.9’ bgs and analyzed for GRO, DRO, RRO, and BTEX. The duplicate sample was also analyzed for PAHs. GRO, DRO, RRO, benzene, toluene, total xylenes, benzo(b)fluoranthene, benzo(k)fluoranthene, and pyrene were detected. The DRO exceeded the 18 AAC75.345 Method Two Migration to Groundwater cleanup levels of 250 mg/kg by values as high as 2,600 mg/kg. However, these levels did not exceed the dermal contact/ingestion cleanup levels. The four benzene levels were estimates by the laboratory and determined to be ND. Their reported levels were twice the DL but below their LOQs which exceeded the cleanup level.
5 boring soil samples and a duplicate sample were submitted for laboratory analysis of GRO, DRO, RRO, and BTEX. The only analytes not detected were benzene and toluene. Most analytical results were ND and the LOQs were below cleanup levels except for one benzene sampling result for the duplicate sample from Boring B1 which was above the 0.025 mg/kg soil cleanup level at 0.0256 mg/kg. However, the laboratory estimated value for the benzene was 0.016 mg/kg which is below its cleanup level. DRO from Boring 1, collected from 7.5 to 9.5 feet bgs, contained the only sampling result concentration greater than any site ADEC cleanup level.
No soil sampling results exceeded the dermal contact/ingestion cleanup levels.
One GW sample each from MW1, MW 3, and MW4, and one duplicate from MW1, were analyzed for GRO, DRO, RRO, BTEX. The main sample from MW1 was also sampled for PAHs. Analytical results for all MWs except for MW1 were ND with their LOQs below the 18 AAC 75.345 Table C GW cleanup levels. GRO, DRO, RRO, BTEX, 1-methylnaphthalene, 2-methylnaphthalene, and naphthalene were all detected in MW1. GRO, DRO, RRO, and benzene were above their applicable ADEC cleanup levels in mg/l at 6.7, 17.2, 1.59, and 0.0178, respectively. Their respective cleanup levels in mg/l are 2.2, 1.5, 1.1, and 0.005.
Sent a letter in response to the review requesting a work plan for continued site characterization, copies for disposal of contaminated IDW, and an updated CSM. |

Offsite Soil or Groundwater Disposal Approved |
Received a copy of a Certificate of Disposal/Recycle for investigative derived waste (IDW) soil and groundwater to Emerald Alaska from the June 2009 site work from Stafford Glashan of Shannon & Wilson, Inc. The certificate was dated 6/23/10 and indicated the date of disposal/recycle was 10/20/09. |

Site Characterization Workplan Approved |
The CSP reviewed a copy of the Shannon & Wilson, Inc. (S&W) work plan titled "Groundwater Sampling, Heating Oil Tank Release, Big Su Lodge, Mile 104 Parks Highway" dated and received July 1, 2010. The work plan is for continued GW monitoring of MWs 1 through 3, installed in 2009, on a semi-annual basis scheduled to occur in October 2010 and April 2011. The proposed project consists of GW water sampling, laboratory testing, IDW management and disposal, and preparing a report of our findings. The GW samples will be sent for laboratory analysis of GRO, DRO, RRO, and BTEX. A drinking water well on site will be analyzed for VOC. A resulting summary report will include a description of field procedures, a scaled site plan, laboratory analytical results with completed ADEC laboratory data checklists, a revised CSM, conclusions, and recommendations as necessary. The work plan was approved as submitted. |

Document, Report, or Work plan Review - other |
On 6/24/11, DEC issued a letter of non objection to Stafford Glascon's request to perform another groundwater sampling event in summer 2011 in response to their "Groundwater Sampling, Big Su Lodge, Mile 104 Parks Highway, Talkeetna, Alaska" report that showed that most monitoring wells that they sampled were dry and one had very elevated measurements for DRO. The report was received at DEC via e-mail on June 3, 2011. The report stated that groundwater sampling events occurred at the site on October 15, 2010 and on April 29, 2011. The findings were somewhat inconclusive because low water was present in the monitoring wells that precluded adequate sampling. One monitoring well where adequate groundwater was present was at MWB1 where elevated diesel range organics (i.e., 48.0 mg/L) and residual range organics (i.e, 2.66 mg/L) were detected above 18 AAC 75.345 cleanup levels (DRO cleanup level is 1.5 mg/L and RRO cleanup level is 1.1 mg/L) on April 29. In addition, a water sample was collected from the drinking water well on site. While the findings noted that there were no detections of contaminants, the report noted that it was not known whether a water treatment system is used.
On June 22, 2011, Sundet discussed the findings briefly with the owner's consultant Mr. Stafford Glashan. During that conversation Sundet noted that CSP had no objection to his request of 6/3/2011 (sent via email) to resample the monitoring wells during a period when a higher water table exists. DEC's 6/24 letter formally notified the owner Sandy Apple of DEC's non objection to her consultant proceeding with another sampling event in accordance to your previously approved work plan and in accordance to CSP’s Draft Field Sampling Guidance document dated May 2010.
