Additional information on the Craney Island sites.

1)  The estimated recovery to date for Tank 125 (PC#1994-0101) is about

17,000 gallons.

2)  I initially told you that the plume for Tank 275 (PC#1988-0664) was

about 8 acres, but I believe that was the estimated size for the Tank

275 and Tank 272 plumes combined.  I think the more accurate estimate is

5 acres for Tank 275 and 3 acres for Tank 272.

3)   I am attaching maps for each site showing the fully delineated

plumes.  As you will see from the dates, these were done early on and do

not reflect the remediation that has been done subsequently.  These

plumes are substantially reduced at this time.

  Subject:    Releases related to field constructed tanks

 

Below is a quick summation of the cases I think you would be interested

in.  

PC#1990-0039 Old Aviation Fuel Tank Farm - Wallops Island Flight

Facility (Opened 7/11/1989)

            The tank farm had different types of tanks.  Three appear to

            have been field constructed.  The product Released was Jet

            Fuel and Aviation Gas.  The tanks, piping and 4,700 tons of

            soil were removed in 1991. The receptor of concern has been

            Town of Chincoteage Water Supply Wells 3A, B, and C,

            although 3A is no longer in use.  No impact to these wells

            has been verified.

In 1958, the base wells across the street shut down due to fuel products

in water

PC#1994-0101 Tank 125 - Craney Island Fuel Depot (Opened 7/11/1993)

            One (1) 2.1 million gallon field constructed tank

            constructed in 1940's, removed from service 1993.

            Product Released: Jet Fuel

            Potential Receptor: Tributary to Craney Island Creek

            Release may have been from the lines to and from the tank

PC#1988-0664 Tank 275 - Craney Island Fuel Depot (Opened 5/16/1986)

            One (1) 2.1 million gallon field constructed tank

            constructed in 1950's and removed from service in mid 1980's

            Product: JP-5

            Threatened receptor: Craney Island Creek - Free product

            found within 20 feet of Craney Island Creek in 1987.

            Release attributed to tank and/or piping failures.  This may

            have involved more than one tank.  Nearby Tank 276 also had

            had a 127,000 gallon overfill in 1996.

            Plume covers between 5 to 8 acres. Volume released estimated

            between 300,000 and 500,000 gallons.  Estimated 143,000

            gallons recovered to date.

PC#2000-5225  Tank 272 - Craney Island Fuel Depot (Opened 5/16/2000)

            One (1 ) 2.1 million gallon field constructed tank

            constructed in the 1950's and taken out of service in May

            2000

            Product: JP-5

            Threatened Receptor: Craney Island Creek

            Release was attributed to piping failures.  I need to check

            the file to see if the tank itself was ruled out.

            Plume covers 3 acres.  Volume released estimated between

            175,000 and 250,000 gallons. Estimated 107,000 gallons

            recovered to date.

PC#2003-5062 Tank 174 - Norfolk Naval Shipyard (Opened 12/2/2002)

            2 million gallon field constructed tank.  Inactive since

            1986.

            Product: #6 Fuel Oil

            Leakage from bottom and wall seams.  Free product was found

            in nearby electrical manhole.

PC#1991-1429 SP Fuel Farm - Norfolk Naval Station (Opened 4/11/1991;

closed 1/6/2009)

            Four field constructed tanks ranging from 230,000 to 565,000

            gallons.  These tanks operated from 1943 to 1992 and stored

            aviation gas. Release may have been due to fuel distribution

            lines.

PC#1988-0665 - Fuel Farm - Oceana Naval Air Station (Opened 10/5/1983)

            Five (5) 570,000 gallon field constructed tanks stored JP-5

            from 1955 to 1997.  Release was from the tanks. Estimated

            56,000 gallons recovered to date.

            Threatened receptor - nearby wetlands.

PC#1988-0666 - Daytank - Oceana Naval Air Station (Opened 10/5/1983)

        One (1) 210,000-gallon tank storing JP-5.  The tank was relined

and is still in use.

There have been multiple releases at this site.  At least one was traced

to holes in the tank.

Two other cases which may have involved field constructed tanks are:

PC#1991-1711 LP Fuel Farm - Norfolk Naval Station

            This site is a 13 acre fuel farm with 4 field constructed

            tanks and 20 regular USTs.  Multiple releases involved.

            Multiple fuel types.   The field constructed tanks are still

            in use. I will have to review the file to determine whether

            the field constructed tanks were involved.  Threatened

            receptor is Bousch Creek Culvert leading to Willoughby Bay.

PC#1991-0436 - The Pier Areas - Norfolk Naval Station

            The CEP area has three 1.2 million gallon field constructed

            USTs which have been relined.  I am not certain whether this

            release was from the tanks or the transmission lines from

            Craney Island.  Product was NSFO and diesel.  Threatened

            receptor is the Elizabeth River.  Sheens were noted on the

            river at one point early on.
