Document, Report, or Work plan Review - other |
Reviewed 2008 work. Five test pits were advanced and three USTs were removed from the ground. GRO, DRO and other petroleum COCs were detected at concentrations above ADEC method 2 cleanup levels. An oily sheen was observed on the groundwater pooled at the base of one excavation. Other potential sources of contamination exist- numerous 55-gallon drums, refuse piles, and two existing ASTs. A release investigation and cleanup plan to address contaminated soil is needed. Also needs a CSM, well search, and UIC search. |

The purpose of the meeting was to discuss the objective for the work planned at the site (Property Assessment and Cleanup Plan) and to give the consultants an opportunity to ask any questions pertaining to the field work. |

Document, Report, or Work plan Review - other |
Received final Preliminary Assessment and Cleanup Planning for ADOT&PF Glenn Highway Maintenance Station and ADF&G Glennallen Facility. Several areas were identified as likely having soil contamination, and additional areas where contamination could have been released to the environment at both the DOT and the DF&G facilities. Contamination was confirmed at 6 DOT locations, yet the extent was not determined although groundwater is presumed contaminated in at least one location. Contamination was confirmed at one location on the DF&G property. Recommendations for additional action provided. |

Site Visit |
DEC staff visited the site during a trip to the Copper River Valley to attend a public meeting. Current site conditions were noted and documented with photographs. Site conditions at the former maintenance station and at the ADF&G properties were discussed with ADF&G Glennallen staff. The community is using two of the structures on the former ADOT&PF site; debris removal and environmental cleanup would help ensure safe continued beneficial use of the property. |

Update or Other Action |
DNR has indicated that the Glennallen Volunteer Fire Department has been lobbying for funding to build a new fire hall and it may be determined during this legislative session. They are still in the beginning stages of planning, but they are trying to identify their first choice for the new site. They are interested in building in the same tract they are currently using, but closer to the hill; probably where the old garage which is just to the north of the current hall is. Preliminary data will be provided to better coordinate. A meeting may be planned with the parties to further discuss the issues. |

Site Characterization Report Approved |
The work consisted of evaluation of approximately 420-cy of soil stockpiled, and sampling the 20 existing groundwater monitoring wells, laboratory analyses of soil and groundwater, and investigative derived waste disposal. The stockpiled soil was characterized for contaminant concentrations to evaluate treatment alternatives. DRO was detected in each stockpile soil sample at concentrations that exceeded the cleanup level for migration to groundwater. In addition, the DRO concentration in one of the project soil samples exceeded the cleanup level for direct contact/outdoor inhalation. One project soil sample also contained a benzene concentration (0.0272 mg/kg) that exceeded the cleanup level (0.025 mg/kg). Based on the results of the stockpile soil sampling, the treatment alternatives will focus on methods effective in the reduction of DRO concentrations in soil, such as using land farming techniques. Groundwater monitoring was carried out to evaluate groundwater quality with respect to known and suspected contaminant sources, as well as on a regional basis. Contaminants of concern exceeding cleanup levels were measured in two of the twenty site wells sampled in October 2013 (Wells MW8 and MW12).
