Welcome to the web site of the Restoration Advisory Board (RAB) of the Twin Cities Army Ammunition Plant.  The mission of the RAB is to provide community involvement in the remediation of the Twin Cities Army Ammunition Plant (TCAAP) located in Arden Hills, Minnesota, which is officially known as the New Brighton/Arden Hills Superfund Site.  The RAB consists of community members and non-community members.  The community members consist of local citizens that live in the area that is affected by the contamination from the TCAAP facility.  Non-community members consist of representatives from the United States Army, the Minnesota Pollution Control Agency (MPCA), the Environmental Protection Agency (EPA Region 5), and Orbital ATK.

The RAB advises the U.S. Army and the regulators (MPCA and EPA) about the cleanup process taking place under the Installation Restoration Program.  It provides an opportunity for local citizen input into the cleanup process.  This input is critical in maintaining community acceptance of the decisions made by the U.S. Army and the regulators.

RAB meetings are held at 7:00 p.m. at the Ramsey County Public Works/Partners Facility, 1425 Paul Kirkwood Drive, Arden Hills, Minnesota.  See the RAB meetings tab for dates of upcoming scheduled meetings.  The public is welcome to attend the meetings.  Minutes of meetings are available in pdf format (meeting minutes).

TCAAP was originally a 4 square mile, U.S. Army-owned facility located in the Twin Cities metropolitan area of Minnesota; however, the U.S. Army has transferred control/ownership of most of the TCAAP property to the Minnesota Army National Guard, Ramsey County, and the City of Arden Hills, and intends to transfer the little remaining TCAAP property in the near future.  The facility was used for the manufacture of small arms ammunition from World War II until the mid 1970’s.  Soil and groundwater contamination has resulted from past manufacturing and waste management practices.  The contamination exists in soil and groundwater on the TCAAP facility itself and in groundwater that extends off the facility.  The U.S. Army in cooperation with Orbital ATK is providing cleanup of the site.  The cleanup is conducted under the outline of the Installation Action Plan (2015 IAP-Public.pdf).
