Small arms ammunition burning area used in 1954.  Two trenches were observed in historical aerial photos (CSSA, 1991a) and confirmed during field study.  57mm, 128A1 ammunition cannisters and fire brick/ammunition piles were also observed.

Outside the security fence line in the northeastern section of facility.

B-3

Landfill area used primarily for garbage disposal and burning trash that was filled in 1990-91 (CSSA, 1991a).  The garbage disposal was field verified.

Inner cantonment area northeast of the main compound, and near well 16.

B-4

Classified burn area used to burn classified documents and trash (CSSA, 1991a).  This area makes up part of a large area of no vegetation surrounding the oxidation pond.  The field survey revealed additional SWMUs in the immediate vicinity.

Inner cantonment area northeast of the main compound, near well 16, in a large unvegetated area.

B-5

Area reported to be used as a fired small arms ammunition brass area.  This area could not be located during the field survey even though the area had been recently cleared.

North pasture near gate

B-6

An area near the homesteads and well G (a low spot near the bend in the road) was reported to be used for miscellaneous solid waste, but could not be found.

10

Fired small arms ammunition brass area where it was reported, but not documented, that CSSA personnel found live rounds.  Field investigation revealed weapons crates and packing near the road, and numerous types of small caliber ammunition scattered brass throughout the field behind them.

B-10

Ammunition disposal area

North of oxidation pond

B-11

Miscellaneous solid waste disposal area used for disposal of ammunition, scrap metal, and construction debris.  Field survey indicated miscellaneous ammunition boxes and arms packing crates, and construction debris adjacent to the creek.

B-12

12, 13

Landfill area for large pieces of scrap metal and weapons were embedded in the 20-foot high hillside and in adjacent pond.

Behind the F-14 storage area

B-13

Engineering trash dump area.  Field survey indicated an area where miscellaneous solid waste was disposed of.  This area has been covered sand semi-compacted, but there are several areas where the cover has eroded, revealing the trash.

East of quarry

B-14

An area believed to be a fired brass area.  This area could not be located during the field survey even with the area upturned from fence repair operations.

Reported to be in the east pasture.

B-15

14

Landfill area for target vehicles and weapons mounts.  The area was observed to be two large rectangular areas of settled soil and stressed vegetation.

Near firing range

B-16

15, 16

Landfill for target vehicles and weapons mounts in the form of two trenches.  Field survey indicated tow trenches in which metal objects were visible on the surface partly covered by soil that had settled into the trenches.

Near firing range

B-19

Miscellaneous solid waste, metal, and weapons identified on CSSA's original list, unable to locate.

West of oxidation pond

B-20

17, 18

Large demolition area where up to 150 pound bombs were destroyed, and a rocket engine was tested.  The area was last used April 30, 1987.  The area was equipped with eleven standpipes for rocket burning and a remote firing bunker.  CSSA personnel indicated that only one standpipe was used once.  The others were never used.  These were probably built in the early 1980s.  Several drums were found in this area but have since been removed in addition to the ten unused stand pipes.

An oxidation pond constructed in 1975, however, a relatively small cleared area can be seen in the aerial photo from 1973 (CSSA 3/17/92).  The pond was lined with a vinyl plastic with a life expectancy of 10 years.  Waste liquids and sludges were tank-collected from the bluing operation are pumped out and trucked to the evaporation pond.  A sample of the top liquid and sludge was taken to Brooks AFB on 20 April 1984 for evaluation at the request of the Texas Department of Health and tested for metals (CSSA, 1984).  In 1985, the RRAD prepared a recommended procedure for closure of the evaporation pond (RRAD, 1985).  the evaporation pond was filled in with dirt in the fall of 1985 (CSSA, 3/17/92).

Inner cantonment area, northeast of main compound

F-14

An inactive, unregistered fenced, diked, materials storage area for drummed halogenated solvents used in degreasing operations (tetrachloroethylene), pesticides, herbicides, used oil, spent chemicals from fingerprint removing operations, and transformers containing PCBs.  This area was used from at least 1984 to 1992, and is the subject of an on-going investigation and remediation.  Additional information can be obtained in the F-14 Accumulation Point Site Assessment Report 9ES, 1993).
