The Army advertised a hearing at 6 p.m. on Sept. 14 at the Edgewood Library, at 629 Edgewood Road, on the proposal.
The request, to both the U.S. Environmental Protection Agency and the Maryland Department of the Environment, would add the Munitions Assessment and Processing System (MAPS) to the existing Aberdeen Proving Ground's permits.
The MAPS was built in 2003 and has operated intermittently under an MDE-issued research, development and demonstration permit originally issued in 2001.
The system was designed to access, drain, decontaminate and detonate legacy chemical munitions that are periodically recovered at APG, according to the advertisement.
The Edgewood Chemical Biological Center, which runs the facility, wants to transition it from the research and development permit to APG's normal controlled hazardous substance permit.
The biological center plans to use parts of the system to support hazardous waste operations on a limited, part-time basis. The MAPS is located in a remote area of APG's Edgewood test range complex.
The application amends two previous requests to add hazardous waste treatment or storage units to the post's organic air emissions control permit. With MAPS, the post will be asking to include six units under the permit
Most of the units affected by the EPA permit have been in operation for years and have complied with the air control requirements, according to the Army's advertisement.
