Dangerous Waste Permit, Agreed Order & Public Participation Plan

Agreed Order (AO)

Ecology has invited the Army to sign an AO for cleanup where releases of hazardous substances occurred. This AO requires the Army to improve polluted areas at 8 Solid Waste Management Units and 13 Areas of Concern at the YTC.

Draft Permit (Permit Lite)

For environmental cleanup at YTC to continue, the Army must have a Corrective Action Permit. The Resource Conservation and Recovery Act (RCRA) requires this permit and outlines how to manage hazardous waste at a facility by federal law.

Public Participation Plan (PPP)

The Public Participation Plan (PPP) encourages community involvement in the cleanup process. It outlines how people can comment on the cleanup process decisions.

When the public comment period ends, we will consider all public comments and may change the documents based on them. After considering all public comments, the documents will become final.

SITE BACKGROUND

The Yakima Training Center (YTC) is a sub-installation of Joint Base Lewis-McChord (JBLM) and is located approximately 100 air miles east of JBLM and is about 10 miles north of the city of Yakima. It encompasses 327,231 acres within Yakima and Kittitas Counties in central Washington State. The YTC population is predominantly transient soldiers performing maneuvers and weapons training with a few permanent residents and on-site workers.

The YTC has been in use for military training since 1941. The Center houses several military or federal government tenants, including the State of Washington Army National Guard Materials and Training Equipment Site, the Marine and Army Reserve Centers, and the Yakima Research Station.

The United States Army is and has been the owner, and JBLM is and has been the operator of the Dangerous Waste Management Facility at the Yakima Training Center since 1941. 

An annual report detailing groundwater monitoring work conducted in 2018 is available. The report covers groundwater monitoring in the Fire Training Pit and Tracked Vehicle Repair/Old Mobilization and Training Equipment Site.

Ecology and the Army are negotiating a legal agreement, called an Agreed Order (AO). The Agreed Order outlines the steps needed to clean up contamination at the Yakima Training Center.


SITE CONTAMINATION

Since 1980, the Army has owned and operated Yakima Training Center as a Dangerous Waste Management Facility. Although the Yakima Training Center has been in nearly continuous use since the early 1940s, there are few records of waste management practices prior to 1984. Available data indicate that potentially hazardous wastes had been generated at the Center in the past. The environmental problems to be addressed include various releases of hazardous substances from all historical military and maintenance operations at the Center including, but not limited to, the use of petroleum-based fuels, solvents, lead-acid batteries, and ordnance, explosives, and other pyrotechnics.


CLEANUP ACTIVITIES

A 1995 Facility Assessment report identified 115 known or potentially contaminated areas within YTC. About a dozen more sites have been discovered and investigated since that time.   As of 2013, all the sites have been investigated and cleanup is nearly complete.  The investigation and cleanup of the sites is summarized in a Draft RCRA Corrective Action Completion Report

Twenty-one sites do not currently meet soil and/or groundwater cleanup standards.
