Projects :: Unexploded Ordnance (UXO)
Ordnance and Explosives Services for Range Decontamination, Clearance, Scrap Disposal and Target Placement, Leach Lake Tactics Range Nellis Air Force Base, Ft. Irwin, CA
NWT's UXO division provided personnel and materials necessary to destroy all OEW encountered, clear both live and inert ordnance, perform battle damage assessments, place targets and dispose of target residue and debris.
Clearance operations involved surface sweeps for the location and identification and removal of all Unexploded Ordnance (UXO), Target Area Debris (TAD), Target Area Scrap (TAS) and Target Area Residue (TAR). Authorized ordnance included, but was not limited to:
- 20/30 mm strafe
- Live and inert general purpose (GP) type munitions up to 200 lbs.
- Training ordnance
- 2.75-inch white phosphorous (WP) marker rockets
- AGM-65 maverick missiles, illumination flares
- Aircraft self-protection chaff and flares
All scrap materials were collected and segregated on the range and certified by UXO personnel prior to removal for disposal. Live UXO items were marked and destroyed by detonation utilizing commercial explosives.
The detonation of ordnance on the active range had been a requirement of NWT from contract inception.
Targets failing QA criteria for acceptable profiles were removed and replaced using Government-supplied, contractor-prepared vehicles from the holding area at ISAFAF.
NWT removed over 500 tons of material from range.
NWT received Exceptional performance reviews in all evaluated categories
Contract Value - $6 Million
Depleted Uranium Clearance and UXO Removal and Disposal, Vieques Live Impact Area, Naval Target Range, Vieques Island, Puerto Rico
New World Technology was contracted to perform radioactive surveys of a live fire range at the Vieques Live Impact Area (LIA) maintained by the U.S. Navy.
NWT was required to treat the RFP as an emergency response request due to the limited time frame of the project and was on-site on site with less than 3 weeks notice of project start date.
NWT mobilized over 25 field personnel (HP Technicians, UXO Technicians, Support and Supervisory personnel) and equipment to the remote location within three weeks of issuance of the RFP.
NWT utilized DGPS equipment and mapping software to develop a complete three dimensional radioactive profile of the operations area.
All areas within the 2.5 square mile operation zone were swept by UXO and HP personnel in order to detect and recover as many Depleted Uranium (DU) projectiles as possible. All wastes recovered were packaged and shipped for disposal by NWT personnel.
All UXO items were marked for disposal by Navy EOD teams.
NWT completed all tasks within 30 days so as not to interfere with the existing training schedule.
Contract Value: $1.3 million
UXO avoidance and clearance operations, Fort Huachuca OB/OD RCRA Pit Closure, U.S. Army, Fort Huachuca, Sierra Vista, Arizona
As part of ongoing RCRA closure activities at Fort Huachuca, several Open Burn (OB) and Open Detonation (OD) pits were identified on the East, West and South ranges. Military personnel utilized these pits, to destroy obsolete, expired, dud and emergency action munitions. Munitions utilized included small arms (such as 5.56 mm, 7.62 mm, .30 caliber, .50 caliber and 20 mm) as well as light and medium infantry munitions (such as 60 mm, 81 mm and 4.2 inch mortars, 4 inch bazooka rounds, as well as 105 mm and 155 mm artillery projectiles.)
NWT performed UXO avoidance and clearance operations in support of the RCRA investigations occurring on the ranges at Ft. Huachuca. The primary goal of the operation was to provide a safe working environment for personnel performing sampling and RCRA removal operations.
NWT developed initial work plans to include prove-out areas for geophysical instruments to be used during subsurface clearance tasks.
Results of testing as well as all work, health & safety and environmental protection plans were approved.
NWT provided Final Survey
Contract Value: $1 Million
Radiological Clearance Including UXO Identification, Naval Air Weapons Station China Lake (NAWSCL), Ridgecrest, CA
NWT was contracted to develop contamination profiles of various gunnery ranges utilized
in the testing of Depleted Uranium (DU) projectiles. Four areas were surveyed:
- Kennedy Stands Area - approximately 1,000 meters by 1,000 meters
- K2 Area - approximately 100 meters by 100 meters
- G6 Area North - 48 meters by 100 meters
- G6 Area South - 48 meters by 100 meters
The total area surveyed was approximately 1,019,600 square meters (~ 252 acres).
UXO sweeps were performed prior to any radiological work. UXO personnel were cross-trained as radiological technicians.
NWT developed and utilized a large multi-sensor towable array to locate DU sources across vast areas of three different ranges. The array utilized Differential Global Positioning System (DGPS) equipment and software to establish grid map coordinates of the separate radiological survey areas on the base. Maps of the area were generated from the DGPS.
Intrusive sampling was performed at one gun butt to determine the level and extent of DU contamination within the berms behind the target.
NWT prepared work plans, including Health and Safety Plans, Quality Assurance Plans and Characterization Survey Plans. The characterization survey plans were designed in accordance with MARSSIM guidance.
Project Value – $677,000
