Site Characteristics

General Site Description:
Site History: (5/12/02 BPM/FUDS) In 1962, the range was essentially divided into two almost equal parts. From 1941 to 1945, the U.S. Army Air Corps used the range for precision bombing. The Air Force used the bombing range from 1948 to 1960. Department of Defense (DOD) improvements to the site consisted of approximately 20 buildings, a flight strip, gunnery range, and five target sites. The Air Force declared the entire site in excess in 1960, and transferred the eastern half of the range to the Department of Navy for use as a practice bombing range (still active - ECSI #3300). After years of negotiating with the State of Oregon, the Air Force transferred the western half to the Oregon Division of State Lands. However, this property, along with other state-owned land in the area (totaling approximately 90,000 acres) was recently sold to a private company for use as irrigated agriculture and dairy. Oregon had also leased this property to Boeing AGRI-Industrial Company. Other landowners include the Port of Morrow, PGE, and the Corps of Engineers. PGE has constructed a coal-fired plant and Boeing has constructed other facilities at the site. Part of the Boeing site is currently in DEQ’s Voluntary Cleanup Program (see ECSI #2595).
Contamination Information: Cantonment Area - There are four trenches on-site, about 4 feet deep, which appear to contain debris and trash. They may contain hazardous materials/wastes. At least one abandoned UST, once used to store gasoline, is on-site. One area is reported to be littered with tattered remnants of heating pipe insulation that may contain friable asbestos.

(7/1/92 DJH) No hazardous materials found in trenches. Site has two bombing ranges. There are possibly small quantities of hazardous substances that likely burned when the bombs were dropped. UST removed under DEQ scrutiny.

(4/26/02, JPD/SAS) pending recordation of deed notice for solid waste disposal treanches, conditional NFA recommended for Cantonment area adjacent to Airport.

(4/11/03 BPM/FUDS) DEQ's Water Quality Program has found high levels of nitrates immediately downgradient of the site, which could be a result of explosives (nitrogen based TNT and RDX both show up in the nitrate test). Nitrate concentrations ranged as high as 50 parts per million (ppm - the drinking-water standard is 10 ppm). In addition, DEQ has found perchlorate contamination in shallow groundwater at the Boeing Engine Test Facility site (ECSI #2595), which is located on the fomer Boardman Air Force Range site. This perchlorate contamination cannot be attributed solely to Boeing's operations, and likely originated from other sources.
Manner and Time of Release:
Hazardous Substances/Waste Types: 1992 - Fire and explosion hazards thought to exist from explosives, phosphorus, and metal incendiaries. Hazardous wastes thought to have been buried in four trenches on-site.
Environmental/Health Threats:
Status of Investigative or Remedial Action: (5/12/02 BPM/FUDS) In 1992, DEQ completed a federal PA at the site. The PA identified concerns related to unexploded ordnance (UXO) at Bomb Target #1 and Bomb Target #2. The PA also identified asbestos and an underground storage tank (UST), which were removed around 1990. The PA concluded that no further action would be performed under the federal CERCLA program, although the site would be listed on DEQ’s ECSI database as needing further action regarding UXO. Follow-up on this site should be performed.

(7/18/05 GMW/SAS) EPA removed this site from its CERCLIS archives in August 2003, as a result of its decision that further activity at the federal level may be necessary at the site. EPA is currently conducting a Site Inspection.

(1/14/08 KJR/SAS) Site proposed for listing on CRL and Inventory (3/20/08 KJR/SAS) No comments received on proposal to list site. Site listed on CRL & Inventory.
