We make every effort to ensure the data presented here is accurate based on the best available information currently on file with DEC. It is therefore subject to change as new information becomes available. We recommend contacting the assigned project staff prior to making decisions based on this information.

Problems/Comments

Texaco leased the property and operated a bulk plant at the site from 1958 to 1982. Willner’s Fuel Distribution then leased the site and operated a bulk plant at the site from 1982 to 1993. A total of 12 aboveground storage tanks (ASTs), five 2,020-barrel capacity and seven 476-barrel capacity, were located on the southern portion of the site. The five larger AST’s were removed from the site in 1994 and historically contained No. 1 and No. 2 diesel, unleaded gasoline, and regular leaded gasoline. The smaller ASTs historically contained No. 10 oil. Two of the ASTs (one large and one small) were reportedly rented to a chemical company and contained silicone. The fuel holding and dispensing facilities were removed from the site sometime between 1994 and 2000. Groundwater at this site is contaminated with diesel range organics (DRO), gasoline range organics (GRO), residual range organics (RRO), and benzene, ethylbenzene, toluene, and xylenes (BTEX). Groundwater conditions are being monitored annually. Also see ADEC File #102.38.006, Saupe Enterprises, Inc.

Action Information

Action Date Action Description DEC Staff
4/1/1989 Update or Other Action (Old R:Base Action Code = SA1 - Phase I Site Assessment (General)).

Samples from monitoring wells MW-1, MW-9, AR-81 and AR-85 did not contain target analytes above the DEC cleanup level. DRO's in wells MW-2 and MW-3 doubled from the previous sampling event. Other wells levels remained fairly consistent with previous levels. ARCADIS BBL recommends eliminating PAH, volatiles (continue BTEX), and EDB analysis in these wells. Tamara Cardona-Marek
1/31/2008 Update or Other Action DEC received the 2007 Site Assessment Report for the Former Chevron Bulk Plant, Former Texaco Bulk Plant, and Former Unocal Bulk Plant. Soil samples and vapor probe gas samples were collected at the site.

ADEC requested that only one sampling event takes place this year and efforts are focused on developing graphs and plume maps that demonstrate contaminant reduction over time. MNA parameters should also be measured at the site during sampling events. Arcadis will do a Phase I assessment to determine if additional plume delineation to the west is needed. Tamara Cardona-Marek

5/14/2014 Meeting or Teleconference Held DEC met with Chevron and ARCADIS to discuss several Fairbanks area sites. Recent investigations suggest that the "western plume" may have a different source than the petroleum plume on this site or the other two adjacent sites, however it is unclear what that source may be. For the near future, Chevron plans on continuing monitoring at this site. Monitored natural attenuation may be proposed as the remedial action in the future. Robert Burgess

Control Type

Type Details
Other The groundwater should not be used for drinking water (or any other purpose) on the site and those properties down-gradient (West) from it until such time that groundwater cleanup levels are achieved. If there is a groundwater well on a property, the water must meet regulatory cleanup levels . If contaminated soil is excavated or groundwater is encountered and must be discharged, DEC should be notified prior to any transport or discharge from the property.

Requirements

Description Details
Groundwater Use Restrictions The groundwater should not be used for drinking water (or any other purpose) until such time that groundwater cleanup levels are achieved. If there is a groundwater well on your property, the water must meet regulatory cleanup levels . If the groundwater exceeds the cleanup levels (as determined by approved water sample analysis), it should either be treated to meet those levels or the well should be decommissioned in accordance with ADEC procedures. The installation of any new groundwater wells should be coordinated with ADEC.
Excavation / Soil Movement Restrictions If contaminated soil is excavated or groundwater is encountered and must be discharged, ADEC should be notified prior to any transport or discharge from the property. Information regarding how the excavated soil is to be stored and/or transported and how groundwater will be contained and/or discharged should be provided to ADEC prior to transport or discharge.
Advance approval required to transport soil or groundwater off-site. Information regarding how the excavated soil is to be stored and/or transported and how groundwater will be contained and/or discharged should be provided to ADEC prior to transport or discharge.
