EPA EPA Proposes Removing a Portion of New Brighton/Arden Hills/ Twin Cities Army Ammunition Plant (TCAAP) from Superfund List Ramsey County, Minnesota Public Comments Accepted through Aug. 22, 2019 U.S. Environmental Protection Agency (EPA) is issuing a document called a Notice of Partial Deletion for the New Brighton/Arden Hills/Twin Cities Army Ammunition Plant (TCAAP) Superfund site in Arden Hills, Minn., from the National Priorities List. EPA requests public comments on this proposed action. The NPL is a roster of the nation's most hazardous waste sites eligible for cleanup under the Superfund program. The Agency with the concurrence of the Minnesota Pollution Control Agency, has determined that under CERCLA (the Superfund law) all appropriate response actions for soil and five aquatic sites in OU2 have been completed, other than maintenance, monitoring, and five-year reviews. "OU" is the abbreviation for operable unit. EPA is interested in your opinion regarding this proposal. The deletion will be effective Sept. 21, 2019, unless EPA receives comments against the deletion by Aug. 22, 2019. If that happens, the Agency will reconsider its proposal in light of those comments. The partial deletion is for all soil located in OU2 of the NB/AH/TCAAP site and for the surface water and sediment (mud) in the five aquatic sites within the OU2 boundary. The aquatic sites are Rice Creek, Sunfish Lake, Marsden Lake North, Marsden Lake South and Pond G. The remaining areas at the NB/AH/TCAAP site, including OU1, OU3, groundwater (underground water) in OU2 and a sixth aquatic area, Round Lake, will remain on the NPL and are not being considered for deletion as part of this action.
