HWAAP-C04
OLD BOMB POPPING FURNACE 1
SITE DESCRIPTION
This site is a metal furnace designated as Popping Furnace No. 1 located approximately ½ mile southwest of Rocket Mountain. It measures 10-ft x 10-ft x 5-ft. It  has metal sides and a door with a grated top and dirt floor. The incinerator is bermed and partially covered with soil. Ash and burn residue cover the furnace floor. An open pit is located behind the site and was used as a disposal site for ash and burn residue. The period of operation began in the 1930's and ended in the 1950's. A 1987 U.S. Army Environmental Hygiene Agency report indicates that the furnace was used to destroy all types of PEP (pyrotechnic, explosives and propellants) by soaking the dunnage with diesel fuel and igniting it. A 1989 investigation conducted by International Technology Corporation included soil sampling of three pits. Evidence of elevated concentrations of metals was found. An investigation in 1994 included airborne ground penetrating radar surveying over the entire site at several target locations. Long term monitoring for the Old Bomb Area started in 1997 and will continue.
PROPOSED PLAN
All ranges, which include some disposal areas at the Hawthorne Army Depot, were originally included in the Installation Restoration Program (IRP), but no progress on restoration could be made because of the dangers of unexploded ordnance (UXO) and inaccessibility to the sites. These sites have now undergone review under the U.S. Army Active/Inactive Range Inventory. Under the Phase II Range Inventory, ranges associated with Old Bomb, Walker Lake Test Range and the NIOTC Range have been determined to be active ranges. Corrective action is required by RCRA permit. NDEP considers this site an uncharacterized site that will be addressed by the U.S. Army when the active range is closed/transferred/transferring. HWAAP-C04 has been incorporated into the Military Munitions Response Program (MMRP). Corrective action requirements at this site will be assessed in five year reviews (next review in FY08) based on groundwater results and change in range status.
Groundwater monitoring for pesticides, volatile organic compounds, and explosives will continue in accordance with the approved base-wide groundwater monitoring plan. There are three wells that cover the eleven Old Bomb sites -- HWAAP-A06B, -A06C, -A06D, -A06E, -C04, -C05, -G01B, -G01C, -I22, -I23, and -K07. Over the years, the monitoring frequency has been reduced and the analyte suite has been refined. No detects have ever been found.
