EPA

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.
