Preliminary Assessment Approved |
Reviewed 1998 UST Closure Assessment. Letter to be sent ot ADOT for any data/reports completed since '98 removal. Heating fuel tank excavation and stockpile needs additional assessment/excavation & remediation. Analytical shows contaminant levels > than ADEC cleanup levels. GW encountered in heating fuel tank excavation. Set up file for regulated gasoline tank. Detected contamination at gasoline tank all below ADEC cleanup levels. No GW encountered during gasoline tank removal. Gasoline tank OK to close. |

Telephone call with Kevin Jones (2355217) current airport manager. He was not aware of any site assessment or additional cleanup that was done. He would look through the files to see if there is any documentation. The stockpile generated during the UST removal is no longer on site. He thinks it may have been thermally remediated at the Homer DOT Highway maintenance station years ago when they cleaned up that site. There's no documentation of this that anyone can find. |

It appears that neither DEC nor DOT has any additioanl information on the planned 00 site assessment & cleanup. An RFP has been developed and sent the the contracting section to conduct a site assessment to determine current site conditions. Once the report is received, DOT will be consulted on any cleanup/remediation that may be required to bring the site to closure. |

A file review revealed that remaining contamination at this site has not been adequately characterized. It is reported that ADOT plans to close the old maintenance shop but no schedule has been established yet. This site is on the CIP, State-Owned sites list. The CSP tenatively plans to conduct further characterization either in FY10, or in conjuction with the decommissioning of the old maintenance shop. |

Phone conversation with Kevin Jones (907-235-5217) or (399-4069). I explained to Kevin our interest in undertaking assessment actions at the former heating oil site. Kevin is the airport manager. Kevin told me that the depth to groundwater is rather shallow in the area, just a few feet. Kevin stated that there is no stockpile remaining at the south end of the runway, where the 44 cubic yards of impacted soil were supposedly staged. Kevin believes these soils may have been taken over to the ADOT- Homer site where they attempted to bioremediate soils and eventually thermally treated them. Kevin told me that the area is now paved to the north of the buildings. The aboveground fuel tank is outside of the fence from the airport proper. Miscellaneous debris exists in the area of the former tank, Kevin told me that this could be cleared out for our assessment activities with little effort. Kevin will take several photos for me and e-mail them to me on Thursday. Kevin told me that Melvin Kremer (235-5215) should have historical knowledge regarding the site. Kevin asked that I contact Ken Puch (283-4665 or 394-0498) who works for ADOT&PF Building Maintenance. I spoke with Ken who asked that we keep him informed with regards to our proposed actions.

Site assessment actions begin with borings drilled at the site. Groundwater not encountered in one boring, encountered but appears clean in another, and at the tank site, contamination extends below the perched groundwater. |

Cleanup Complete Determination Issued |
Cleanup Complete Determination Issued. Residual soil contamination remains in the area of the former 3,000-gallon underground heating fuel oil tank removed in November of 1998. Soil concentrations exceed the Table 1B Method Two - Soil Cleanup Levels 'Migration to Groundwater' with DRO at 417 to 10,300 mg/kg at 3 to 9.5 feet bgs, Benzene at 0.0609 to 4.88 mg/kg at 5.5 to 9.5 feet bgs, Toluene at 26.0 mg/kg at 5.5 feet bgs, Ethylbenzene at 18.9 mg/kg at 5.5 feet bgs, and xylenes at 99.5 mg/kg at 5.5 mg/kg. The shallow groundwater is not used as a drinking water source. The entire airport is connected to the City of Homer's municipal water system. The soil quality data submitted to date is located in the December 1998 UST Closure Assessment ADOT&PF Homer Airport Maintenance Facility, prepared by Shannon & Wilson, and in the November 2010 Site Characterization ADOT&PF Homer Airport HOT (Kachemak Drive), Homer, Alaska, prepared by Shannon & Wilson. |
