Meeting Summaries

Next RAB Meeting:

The Army is hosting a RAB/public meeting on July 20, 2021, at 7:00 p.m. CST. Rather than the normal cleanup update, this meeting will be focused on cleanup at Round Lake. The Army has prepared a Proposed Plan to document the preferred alternative of those evaluated in the Feasibility Study for Round Lake. This meeting is being conducted virtually to maintain social distancing and protect the health of the community during the Coronavirus Disease 2019 (COVID-19) public health emergency.

The Army will also be hosting an open house on July 20, 2021, from 10 a.m. until 3 p.m. at the Minnesota National Guard Facility – Arden Hills Army Training Site (AHATS). Army personnel (as well as other government agency representatives) will be on hand to answer any questions about the Proposed Plan to address contamination in Round Lake. Poster stations will be set up in the AHATS gymnasium at 4761 Hamline Ave N in Arden Hills with some of the same information to be presented at the RAB meeting later that evening. Handouts will be available in print. We encourage community members to attend the open house to have their questions answered in person. Please call (651) 282-4420 for directions.

The Proposed Plan Public Comment Period is open from July 9 – August 13, 2021

NOTE: Open house attendees will be required to adhere to all National, Regional, and State COVID-19 mandates and guidelines in place at the time of the Open House.

Both the open house and RAB meeting are open to the public. Anyone interested in or wanting information about the TCAAP cleanup activities for Round Lake is invited to attend.

Previous RAB Meetings:


The TCAAP RAB was established in 1996. It remained active until 2015. The RAB was never dissolved or adjourned. The Army solicited for interest in participating on the TCAAP RAB in April 2020 but did not receive sufficient interest. However, in October 2020 the Army began receiving emails from interested community members and had sufficient interest to continue the RAB. The Army contacted other local stakeholders to solicit their interest in participating and held the first TCAAP RAB meeting in more than five years in January 2021.
The Mission Statement and  Operating Procedures from the former TCAAP RAB are available for review, as well as a list of former members. If you are interested in participating on the RAB, please see below How to Get Involved in the RAB.


What is a Restoration Advisory Board or RAB?

A RAB is a stakeholder group that meets on a regular basis to discuss environmental restoration at a specific property that is either currently or was formerly owned by the Department of Defense (DoD), but where DoD oversees the environmental restoration process. RABs enable people interested in the environmental cleanup at a specific installation to exchange information with representatives of regulatory agencies, the Army, and the community. While the general public can comment on DoD’s environmental restoration program, RABs offer a focused and interactive opportunity to participate in the environmental restoration process.

The RAB provides the community with the opportunity to become involved in the environmental restoration process at the former Twin Cities Army Ammunition Plant either as a RAB member or through attendance at RAB meetings. RABs offer members the opportunity to influence cleanup decisions through discussion and to provide input to the Army’s decision makers. Because representatives of the environmental agencies overseeing cleanup participate in the RAB, the RAB offers members and the public the opportunity to share their questions, concerns, and ideas with agencies involved in the cleanup.

What does the RAB do?

The RAB reviews documents prepared by the Army about the environmental restoration process taking place at the former TCAAP and provides an opportunity for local citizen input into the cleanup process. The status of each of the sites undergoing cleanup is available on this website. Community input is critical to ensure understanding and acceptance of the decisions made by the U.S. Army, the MPCA, and the U.S. EPA. Please review the mission statement and operating procedures or minutes of previous meetings (below) for more information.

How do I get involved in the RAB?

RAB members have been selected and are representative of the affected community near the former Twin Cities Army Ammunition Plant. RAB meetings are open to the public. Meetings are being held virtually during the COVID pandemic to help keep everyone healthy and safe. Meetings are announced on this RAB page, on the front page of the website, and in local newspapers. When there are vacancies on the RAB, the Army will solicit for new members on the website, in local newspapers, and through current RAB members.
