Document, Report, or Work plan Review - other |
On this date, ADEC received the Work Plan for Soil Borings and Sampling Whittier Rail Yard, submitted by Clarus and dated May 2010. Three soil borings will be advanced at the former UST location. Two soil samples will be collected from each boring at 5 foot intervals. The soil samples will be collected from the groundwater interface and/or from the highest field screen result. The soil samples will be analyzed for BTEX and GRO. A total of seven soil samples will be analyzed, which includes the duplicate. |

Document, Report, or Work plan Review - other |
On this date, ADEC received Subsurface Soil Investigation Whittier Rail Yard, submitted by Clarus, dated December 27, 2010. Three soil borings were advanced at the former UST location: one within the footprint of the former gas UST excavation; and two advanced, east and north, downgradient toward the harbor. Two soil samples were collected from each boring at 5 foot intervals. The soil samples were collected from 4ft. bgs, 8.0 ft. bgs, and 11.0 ft. bgs. A total of seven soil samples were analyzed for BTEX and GRO, which includes the duplicate. A soil sample collected from the north bore hole at the 11 ft bgs GW interface, contained benzene at 0.0459 mg/kg, toluene at 7.22 mg/kg, ethylbenzene at 19.3 mg/kg, and GRO at 1,550 mg/kg. All other soil samples were either ND or below cleanup levels. |

On this date, ADEC received the Work Plan for Soil Boring Groundwater Whittier Railyard submitted by RSE. Three soil borings will be advanced and completed as monitoring wells. One boring will be advanced at the UST area and two borings will be advanced downgradient toward the ocean. Two soil samples will be collected per boring plus one duplicate. One sample will be collected from the GW interface and one will be collected from the highest PID reading. One groundwater sample will be collected from each MW plus one duplicate. |

Update or Other Action |
On this date, ADEC received the Subsurface Soil and Groundwater Investigation Whittier Rail Yard submitted by RSE, dated January 2012. Three soil borings were advanced and completed as monitoring wells RSE-1, RSE-2, and RSE-3. One boring was advanced at the UST area (RSE-3) and two borings were advanced down gradient toward the ocean (RSE-1 & RSE-2). One soil sample was collected per boring at the GW interface 7 to 9 ft. bgs plus a duplicate. The soil samples did not contain petroleum constituents above ADEC cleanup levels, however a hydrocarbon sheen and odor was noted. Soil screened at RS-3 at a depth of 1 to 3 feet bgs contained a PID reading of 103.1 ppmv and HC odor, but an analytical soil sample was not collected. Groundwater samples collected from the three monitoring wells did not contain contamination above ADEC cleanup levels with the exception of RSE-1, which contained DRO at 1.79 mg/L. |

Site Characterization Report Approved |
On this date ADEC received the ARRC Whittier Rail Yard Ground Monitoring Report submitted by RSE, dated January 2013. DRO, the only detectable petroleum constituent, was encountered in RSE-1 at 0.219 mg/L and RSE-3 at 0.232 mg/L. A petroleum sheen was also noted in the RSE-1 purge water. Groundwater was encountered 12.08 to 12.92 feet below top of casing. A soil sample collected 18 inches bgs (adjacent to RSE-3 from an area with an historic elevated PID reading 0 to 3 feet bgs) contained detectable petroleum constituents but below migration to GW cleanup levels. |

Site Characterization Report Approved |
On this date, ADEC received the Groundwater Monitoring Report Whittier Rail Yard submitted by FES dated November 20, 2013. RSE-2 was not sampled due to damage and surface water infiltration. Three groundwater samples collected from RSE-1 and RSE-3 did not contain detectable levels of petroleum constituents. Depth to groundwater was 10.5 and 9.39 ft. bgs in RSE-1 and RSE13 respectively. Groundwater samples were collected during high tide and during a period of rain. |

Site Characterization Report Approved |
On this date, ADEC received the Groundwater Monitoring Report Whittier Rail Yard submitted by FES dated October 9, 2014. Depth to groundwater was 12 to 14 feet bgs and appeared to be heavily influenced by tidal activity. Groundwater samples were collected during low tide. Four groundwater samples collected from RSE-1, RSE-2, and RSE-3 did not contain contaminant concentration above ADEC cleanup levels. |

Cleanup Complete Determination Issued |
The Alaska Department of Environmental Conservation (ADEC), Contaminated Sites Program, has completed a review of the environmental records associated with the ARRC Whittier Rail Yard site. Based on the information provided to date and the administrative record, the ADEC has determined that the contaminant concentrations remaining on site do not pose an unacceptable risk to human health or the environment. No further remedial action will be required as long as the site is in compliance with established institutional controls. |
