Hawthorne Army Depot Installation Action Plan MARCH 2001 INSTALLATION ACTION PLAN 2001 Hawthorne Army Depot PURPOSE The purpose of the Installation Action Plan (IAP) is to outline the total multi-year restoration program for an installation. The plan will define all Installation Restoration Program (IRP) requirements and propose a comprehensive approach and associated costs to conduct future investigations and remedial actions at each Solid Waste Man- agement Unit (SWMU) at the installation and other areas of concern. In an effort to coordinate planning information between the IRP manager, major army commands (MACOMs), installations, executing agencies, regulatory agencies, and the public, an IAP has been completed for Hawthorne Army Depot. The IAP is used to track requirements, schedules and tentative budgets for all major Army installation restoration programs. All site specific funding and schedule information has been prepared according to projected overall Army funding levels and is therefore subject to change during the document’s annual review. Under current project funding, all remedies will be in place at Hawthorne Army Depot by the end of 2010.

Hawthorne Army Depot - Installation Action Plan Installation Information & Description - Page 2 INSTALLATION DESCRIPTION HWAD is currently a Government owned/Contractor operated (GOCO) facility. Day & Zimmermann Hawthorne Corporation [DZHC, Former Day and Zimmermann/Basil Corporation (DZB)] is the current operating contractor. The government and DZHC employ approximately 500 personnel. The current mission of HWAD is to receive, issue, store, renovate, inspect, demil, and dispose of conventional ammunition. The installation was originally constructed in 1928 as a US Naval Ammunition Depot. The early mission of the depot was to store, service, and issue ammunition to the Pacific Area. Following World War II, the Depot was actively involved in the demolition of various types of allied and enemy ammunition. The role of the Depot was also expanded to include receiving, renovating, loading, maintaining, storing, and issuing ammunition, explosives, expendable ordnance items, and/or weapons and technical ordnance materials. The Depot was also used to test weapons and dispose of unserviceable and/or dangerous ammunition and explosives. In 1977 the Depot was transferred to the U.S. Army renamed Hawthorne Army Ammunition Plant (HWAAP). After the transfer, HWAAP was redesignated as a GOCO Plant in 1980 and operating under the direction of DZB. Its mission in 1980-1994 was to (1) receive, produce, assemble, load, issue, store, renovate, inspect, test demilitarize, and dispose of conventional ammunition; (2) operate and/or maintain in operational readiness cast and fuel-air explosive loading plants, rocket assemble plants, and medium/major caliber assembly lines; (3) provide special/experimental high explosive casting, extruding, and pressing; fuel air explo- sive loading and support services to designated research and development activities; (4) provide storage facilities for war reserve ammunition, and maintain designated ammunition in a state of readiness for mobilization, including assembling or otherwise providing base unit materials; and (5) conduct testing of solid propelled munitions, high explosive warheads, mechanical
