Blue Grass Army Depot – Temporary Authorization Request Approval

Temporary Authorization Request: On June 23, 2014, the Blue Grass Army Depot (BGAD) and systems contractor Bechtel Parsons Blue Grass (BPBG), submitted a Temporary Authorization Request (TAR) to Kentucky Department for Environmental Protection (KDEP). This submittal, along with the information required in accordance with the provisions of Resource Conservation Recovery Act (RCRA), allow for only beginning the site work and partial construction of an Explosive Destruction Technology (EDT) system, while the Class 3 RCRA Permit Modification to add the EDT is being reviewed by KDEP. This TAR was approved by KDEP on Aug. 22, 2014, for the regulatory time period of 180 days.

The BGAD located near Richmond, Ky., provides conventional ammunition services, chemical defense equipment management and other industrial services for the Department of Defense. BGAD is also responsible for safekeeping and storage of the chemical weapons stockpile at the depot as well as demilitarization through tenant support operations.

The tenant, Blue Grass Chemical Activity (BGCA) is responsible for executing the storage mission. The Program Executive Office, Assembled Chemical Weapons Alternatives program, known as PEO ACWA, is the agency responsible for managing the chemical demilitarization mission through the Blue Grass Chemical Agent-Destruction Pilot Plant (BGCAPP). This plant is being built at the depot to safely and efficiently destroy GB (sarin) and VX nerve agents in rockets and artillery projectiles, utilizing neutralization followed by supercritical water oxidation (SCWO).

Additionally, an EDT system will augment BGCAPP’s main pilot plant to destroy approximately 15,000 mustard agent filled 155mm projectiles and two Department of Transportation (DOT) 3A bottles, currently in the Blue Grass stockpile. BGCAPP has selected an EDT system to destroy the mustard stockpile because solidification of the mustard agent was found in a significant number of mustard projectiles, rendering them unsuitable for the automated neutralization process that will be used at the BGCAPP. The EDT system will be employed to destroy the entire Blue Grass mustard stockpile to augment the main pilot plant destruction process.

As such, the mustard-filled projectiles and two DOT bottles are subject to a Class 3 Modification to BGAD’s RCRA Hazardous Waste Permit. BGAD, in collaboration with the systems contractor BPBG, formally submitted this permit modification request to the KDEP in March 2014. This permit modification has completed the 60-day public notice process in coordination with KDEP, as required by the RCRA regulations.
