Plum Brook Ordnance Works

PBOW Historical PhotoPlum Brook Ordnance Works (PBOW), located near Sandusky, Ohio, produced trinitrotuluene (TNT), dinitrotuluene (DNT) and Pentolite from 1941 to 1944 for use during World War II. Currently the National Aeronautics and Space Administration (NASA) Glenn Research Center occupies the site.

Possession of the property was transferred to the Ordnance Department in 1946, then to the War Assets Department, and finally to the General Services Agency (GSA) in 1949. NASA acquired the property in 1963 and presently maintains and utilizes approximately 6,500 of the original 9,000 acres.

Numerous environmental investigations have been conducted at the site to determine the level of contamination from the ordnance manufacturing processes. Current investigations began in the early 1980s and since then 16 areas of concern (AOC) have been identified. Recent investigations conducted by U.S. Army Corps of Engineers (USACE) Huntington District have initiated remediation activities under the Defense Environmental Restoration Program for Formerly Used Defense Sites (DERP-FUDS). The USACE is the federal agency responsible for environmental restoration at Department of Defense installations. Huntington District USACE works closely with the Ohio Environmental Protection Agency (EPA), National Aeronautics and Space Administration (NASA) and the Restoration Advisory Board (RAB), a group of concerned citizens from the communities surrounding the PBOW area.

PBOW is located near Sandusky, Ohio, four miles south of the Lake Erie Port of Sandusky, and consists of 9,009.32 acres of land plus 1.35 acres for a pump station. Located primarily in Perkins Township, most of the southeastern portion of PBOW lies in Oxford Township. The eastern edge of the site extends into Huron and Milan Townships. The site is bounded by U.S Route 250 on the east, County Road 43 on the west, Bogart Road on the north and Mason Road on the south. Most of PBOW is situated on undisturbed forested land, while the area surrounding the site is rural and agriculturally developed.

This website is intended to provide information concerning the environmental restoration activities at PBOW to the general public. The material contained herein will be updated as activities at the site progress, so check back often or contact USACE Huntington District at 1-800-822-8413.

Site History

PBOW Historical Photo The original site was acquired by the Department of Defense (DoD) in 1938 for the manufacture of ordnance, and consisted of 9,009.32 acres of land plus 1.35 acres for a pump station. In the early 1940s the U. S. Army contracted with the Trojan Powder Company to manufacture 2.4.6-trinitrotoluene (TNT), dinitrotoluene (DNT), and pentolite at Plum Brook Ordnance Works (PBOW). Production began on December 16, 1941 and continued through late 1945. During production more than one billion pounds of ordnance was manufactured. The Army conducted decontamination and decommissioning of many of the buildings and structures associated with the manufacturing of ordnance. It is estimated that 65% of the necessary decontamination of PBOW was completed by December 1945. At midnight on December 17, 1945, physical custody of the PBOW was transferred from the Trojan Powder Company to the U. S. Army Ordnance Department. Renamed Plum Brook Depot, it was used for ammunition storage. The Ordnance Department became the accountable agency and the U. S. Army Corps of Engineers assumed responsibility for maintenance and custodial duties at the PBOW from January 1 through June 30, 1946. The property was further decontaminated and then transferred to the War Assets Administration in August 1946. From 1946 to 1949 the property was protected and maintained by Matthew-Levio and Sons. In 1949 it was transferred to the General Services Administration which maintained oversight of the facility. Ravenna Arsenal conducted further decontamination efforts from 1954 to 1958. The National Aeronautics and Space Administration (NASA) accepted approximately 8,400 acres of the facility in 1963 after Ravenna Arsenal certified that the PBOW had been completely decontaminated and was suitable for unrestricted future use. After acceptance of the PBOW, NASA identified further areas that required decontamination. In 1964, NASA continued site decontamination and the removal of structures. In 1978, NASA declared approximately 2,150 acres of land as excess. The Perkins Township Board of Education uses 46 of the excess acres as a bus transportation center while much of the remaining excess property was reclaimed for farmland. In 1994 the PBOW was determined to be eligible for the Defense Environmental Restoration Program for Formerly Used Defense Sites.
