SA 82, P-80/P-81 Buildings, USTs 10579, 10587, and AST 10333 Petroleum Site

Background
The P 80/P 81 Buildings were used by the former NSGA. One above ground storage tank (AST), two underground storage tanks (USTs), and associated piping near Building P-80 are likely sources of petroleum hydrocarbons detected at the site. Investigations were performed from 1996 to 2000. Hydrocarbon concentrations in groundwater exceeded established cleanup levels.

The OU A Record of Decision (ROD) identified free-product recovery as the interim remedy for this site in 2000. Free product was detected intermittently in the two wells situated in the former UST locations. Passive product recovery yielded a total of 0.04 gallon. Free product has not been observed in any monitoring well in the vicinity of the P 80/P 81 Buildings since July 1998, and the criterion to cease free-product recovery was met. The 2005 Decision Document identified limited groundwater monitoring as the final remedy selected for this site.

Petroleum Institutional Controls

  • Inspections and Reporting
    The ICs identified in this plan will be inspected and reported on an annual basis, or as necessary. Annual site inspection reports will present the results of inspections. The annual reporting requirements will be included in CERCLA 5-year reviews.

  • Land Use Restrictions
    Commercial and industrial land uses and continuing residential land uses where housing exists in the Downtown Area are permitted in accordance with the Interim Conveyance document. Residential housing is allowed in existing housing units located at Amulet Housing, Arctic Acres Housing and SWMU 62. Future residential housing construction will be evaluated for impacts to ongoing petroleum cleanup activities.

  • Soil Excavation Restrictions
    Soil excavation notifications are required for all the Downtown Area Petroleum sites with ICs. The excavation notifications will be required for each proposed excavation below 2 feet. The notifications will be evaluated to determine whether a proposed project at an IC site is consistent with the land use restrictions. The notifications are an additional tool for the Navy to receive timely information (in the absence of local zoning requirements) to monitor land use restrictions.


Petroleum Engineering Controls

  • Other Engineering Controls
    Other engineering controls include landfill caps (CERCLA sites), free-product recovery wells (SAERA sites), and free-product recovery trenches (SAERA sites).
