Problems/Comments

This Event ID covers several underground storage tanks which were removed in 1992 and 1996. Decommissioning Reports were reviewed again in 2007 and it was determined that all tanks with the exception of Building 300 Tank 39-A-4 could be closed. Activities associated with regulated tank 39-A-4 will be the only ones tracked on this Event ID. Other contaminated areas will be tracked under the FAA Juneau Station site, hazard ID 1450, as they are not associated with a regulated tank.

3/28/2007	Update or Other Action	From a letter dated 3/28/07: Tank 39-E-1: This 1000 gallon regulated underground storage tank was used for providing gasoline to an emergency generator at Building 622 at the Localizer Display Approach (LDA). The tank was removed in May 1997, as documented in the Decommissioning Assessment Report dated November 1997. Twenty (20) cubic yards of petroleum contaminated soil was removed and sent to a disposal facility in Washington state. Five (5) confirmation samples were collected from the limits of the excavation at depths ranging from 4-4.5 feet bgs and analyzed for DRO, GRO, BTEX, and lead. The highest concentrations detected were DRO: 29 mg/kg, GRO: 8 mg/kg, benzene: 0.014 mg/kg, ethylbenzene: 0.05 mg/kg, toluene: 0.05 mg/kg, xylenes: 0.1 mg/kg, and lead: 5 mg/kg. All analytical results were below DEC’s method two cleanup levels. Site closure is approved for this tank site.	Anne Marie Palmieri
3/28/2007	Update or Other Action	From a letter dated 3/28/07: Tank 39-D-1: This 500 gallon regulated underground storage tank was used for storing diesel fuel at the MALSR. The tank was removed in May 1997, as documented in the Decommissioning Assessment Report, dated November 1997. No petroleum contaminated soil was discovered during the tank removal. Two (2) confirmation samples were collected from the limits of the excavation at 4-5’ bgs and one (1) below the fuel lines at 1’ bgs which were analyzed for DRO and BTEX. All analytical results were non-detect, thus, DEC’s method two cleanup levels were met. Site closure is approved for this tank site.	Anne Marie Palmieri
3/28/2007	Update or Other Action	From a letter dated 3/28/07: Tank 39-B-1: This 100 gallon regulated underground storage tank was used for storing diesel fuel at Building 4213 at the Remote Transmitter Receiver (RTR). The tank was removed in June 1997, as documented in the Decommissioning Assessment Report, dated November 1997. Two (2) cubic yards of petroleum contaminated soil was removed and to a disposal facility in Washington state. The excavation could not be expanded due to the proximity of the building. Three (3) confirmation samples were collected from the limits of the excavation and analyzed for DRO and BTEX. Additional contamination was found to be present in the excavation hole with the highest DRO sample result of 4300 mg/kg. All BTEX results were non-detect. As documented in the Remedial Investigation, dated 1998, six (6) soil borings were advanced with three of those turned into monitoring wells. All soil and groundwater sample results were non-detect, with the exception of one diesel-range organics soil sample result of 23 mg/kg. The location of the former UST has been covered with a concrete pad and a new above-ground storage tank placed there. DEC determines that the contamination at the Tank 39-B-1 location is likely localized in extent with further characterization and removal not possible until the building and concrete pad are removed. As the contamination plume is likely stable, this site can be conditionally closed until the building and concrete pad are removed; at such time the remaining contamination will need to be addressed.

1/14/2010	Site Characterization Workplan Approved	Approved work plan dated November 2009 for (1) characterizing the horizontal and lateral extent of soil contamination resulting from the heating oil release from the AST at the Maintenance Shop and (2) two rounds of groundwater monitoring for DRO, GRO, and BTEX near the former UST at Shop Building 300.	Melody Debenham
1/25/2010	Document, Report, or Work plan Review - other	Received Technical Memorandum summarizing November 2009 groundwater sampling from 3 wells on site. Groundwater samples were analyzed for GRO, DRO, RRO, and BTEX. Benzene is the only compound reported above the cleanup level, at 11.1 ug/L in MW-A18 and 7.41 ug/L in MW-A10.	Melody Debenham
9/29/2010	Document, Report, or Work plan Review - other	Received Technical Memorandum summarizing July 2010 groundwater sampling from 3 wells on site. Groundwater samples were analyzed for GRO, DRO, RRO, and BTEX. Benzene is the only compound reported above the cleanup level, at 11.1 ug/L in MW-A18.	Melody Debenham
1/6/2012	Document, Report, or Work plan Review - other	Approved the technical memorandum describing the hydrologic study at the Juneau Sector Field Office from November 2010 to November 2011.	Melody Debenham
6/23/2015	Document, Report, or Work plan Review - other	Received draft work plan describing petroleum contaminated soil removal and groundwater sampling at the Juneau Sector Field Office yard.	Melody Debenham
12/13/2016	Document, Report, or Work plan Review - other	Received final Contaminated Soil Removal and Groundwater Sampling Report for the Juneau Sector Field Office Yard.	Melody Debenham
9/12/2017	Update or Other Action	Reviewed data for USTs on site and found that there are 3 USTs that were not closed in 2007: 39-A-004, 39-B-001, and 56-C-003. Results of investigation efforts indicate that the UST 39-B-001 can now be closed.	Danielle Duncan
4/27/2018	Update or Other Action	Sent an update on the site needs this date.	Danielle Duncan
1/23/2019	Update or Other Action	Per the FAA, there are no funds available for a cleanup and the site is a low priority for them.	Danielle Duncan
