Exposure Tracking Model Ranking |
A new updated ranking with ETM has been completed for source area 77599 Diesel and gasoline USTs and Dispenser Island for the vapor intrusion pathway. The subsurface contamination extended beneath the building foundation and the sidewalk; the lateral and vertical limits were not established. The facility currently operates as a restaurant; soil vapors from residual gasoline contamination could pose an exposure risk to the occupants.

Document, Report, or Work plan Review - other |
DEC evaluated the Nortech Site Characterization Work Plan for the Chevron - Hoovers LUST Source Area 77599 and provided approval with comment by electronic mail. Borings will be advanced at locations where the residual benzene and gasoline soil contamination exceeded human health based cleanup levels (dispenser island) and residual diesel contamination exceeded migration to groundwater cleanup levels (Tank 4). Sample collection will begin in April 2011. |

Final Cleanup Report Reviewed |
DEC has reviewed Site Assessment Report by Nortech Environmental Engineering introduces new soil data on the petroleum release from regulated UST systems at the facility. The sample data collection methods were performed by qualified person(s) and are consistent with methodology in the DEC approved site assessment work plan and as prescribed in 18 Alaska Administrative Code (AAC) 78.090 and 18 AAC 78.230. The data meet field and laboratory report quality assurance criteria in Contaminated Sites Program guidance documents and the UST Procedures Manual. The Report documents current and historical results of field and laboratory investigation into petroleum release from regulated UST systems as required by 18 AAC 78.230 - 18 AAC 78.280 and 18 AAC 78.600 - 18 AAC 78.625 and therefore meets the final corrective action reporting requirements in 18 AAC 78.276. The greatest concentration of hydrocarbons in the soil borings were found in one sample: GRO at 3.39 mg/kg, DRO at 31.2 mg/kg, benzene at 0.0142 mg/kg, toluene at 0.110 mg/kg, ethylbenzene was not detected and total xylene compounds at 0.2504 mg/kg.

Cleanup Complete Determination Issued |
The cleanup actions to date have served to excavate and adequately remove contaminated soil from the site. Based on the information available, DEC has determined no further assessment or cleanup action is required. This determination is in accordance with 18 AAC 78.276(f) and does not preclude DEC from requiring additional assessment and/or cleanup action if future information indicates that this site may pose an unacceptable risk to human health or the environment. Although a Corrective Action Complete determination has been granted for this facility, off-site movement or use of potentially contaminated soil in a manner that results in a violation of 18 AAC 70 water quality standards is unlawful and in accordance with 18 AAC 78.600(h) approvals from DEC is required. |
