Document, Report, or Work plan Review - other |
In September 2013, two 5,000 gallon gasoline underground storage tanks, dispenser, and associated piping was removed. Approximately 70 cubic yards of contaminated soil was placed in super sacks and is currently stored on site. A total of nine soil samples were collected from the excavation and analyzed for gasoline range organics (GRO), benzene, toluene, ethylbenzene, xylenes, and naphthalene. Contamination remains in the base of the excavation. GRO concentrations range from non-detect to 986 mg/kg, benzene concentrations range from non-detect to 3.7 mg/kg, and toluene concentrations range from 0.0477 mg/kg to 14.5 mg/kg. Based on a review of the report, the following information needs to occur before this site can be considered for closure:1.The nature and extent of soil and groundwater contamination must be adequately delineated. 2.A conceptual Site Model (CSM) is required that satisfactorily demonstrates that there is no risk to human health or the environment.

Document, Report, or Work plan Review - other |
The Alaska Department of Environmental Conservation (ADEC) received and reviewed the Site Characterization Work Plan and the Landspreading Work Plan for the C&L Tesoro site. The work plans proposed to advance between 6 and 10 soil borings to delineate the nature and extent of contamination, install three temporary monitoring wells, one permanent monitoring well, and land spread the previously stockpiled material at a proposed location. The Contaminated Sites Program (CSP) did not object to the work; however, requested that one of the water samples be submitted for lead analysis. |

Document, Report, or Work plan Review - other |
Reviewed the Site Characterization Report, dated January 28, 2015. Six soil boring were advanced at this site in August 2014 to better delineate the extent of contamination, and to investigate the potential impacts to groundwater. Most of the borings consisted of a gravely material in the top four feet, followed by clay down to about 18 feet below ground surface (bgs). The deepest boring was advanced to 27 feet bgs. Many of the boring exhibited moisture, but were not saturated, and did not produce necessary levels of water. Therefore, water samples were not collected during this investigation. At least one soil sample from every soil boring was submitted for laboratory analysis of gasoline range organics (GRO), and benzene, toluene, ethylbenzene, and xylenes (collectively known as BTEX). All sample results were below laboratory detection limits and/or ADEC cleanup levels. In addition to the soil boring investigation, water samples were collected from two nearby drinking water wells (DWWs) by the property owner in January 2015. Contamination was not identified in either DWW.

Update or Other Action |
Email correspondence with RP indicates that the stockpile is actively being worked. Samples are slated for summer 2017. |

Document, Report, or Work plan Review - other |
Reviewed the Landspread Soil Evaluation Work Plan, dated May 9, 2017 for the C&L Tesoro site, located at 1610 Kanakanak Road in Dillingham, Alaska. Proposed activities generally consist of collecting analytical soil samples from the base and sidewalls of the land farm soils. |
Joshua Barsis |
| 10/9/2017 |
Update or Other Action |
Landfarm sampling event postponed until September 2018, as the landfarm soils are most likely still contaminated at levels above the applicable ADEC cleanup levels. This assumption is based on odor and the number of tilling events that have occurred. |
Joshua Barsis |
| 9/19/2018 |
Update or Other Action |
Reviewed a letter, dated August 27, 2018, that requested an extension for implementing the approved work plan until 2019. ADEC approved the extension in a letter dated September 19, 2018. |

Workplan Requested |
Overdue work plan request sent to the Responsible Party. No action has been taken since 9/10/2018 when ADEC reviewed a letter, dated August 27, 2018, that requested an extension for implementing the approved work plan until 2019. ADEC approved the extension in a letter dated September 19, 2018. |
