Work to clean and clear the former Twin Cities Army Ammunition Plant in Arden Hills is complete, county officials announced Friday.
The 427-acre site, once the largest contaminated site in Minnesota, has been cleaned to residential standards, officials said in a statement. Ninety-three percent of the materials removed from the site were recycled or reused in new roadways there and in other parts of the Twin Cities.
The cleanup paves the way for redevelopment of the site, now called Rice Creek Commons.
“When we decided to purchase the TCAAP site in 2013, our goal was to return this vacant property into the economic and social engine that it once was,” said Ramsey County Commissioner Rafael Ortega. “Completing the cleanup puts us one step closer to creating a vibrant development that will strengthen our community.”
Saint Paul-based Carl Bolander & Sons completed the demolition and environmental remediation work on time and on budget, county officials said.
The county is now working with the Minnesota Pollution Control Agency (MPCA) through its Voluntary Investigation and Cleanup program and the Environmental Protection Agency to verify the work. The county will then request that the MPCA and EPA remove the site as a Superfund for soil contamination in 2016.
