Portsmouth city and school officials are negotiating an agreement with federal regulators to clean up a contaminated property. If approved, the agreement with the Environmental Protection Agency wouldn’t cost any local tax dollars. Deputy City Manager Nita Mensia-Joseph tells The Virginian-Pilot that the agreement would allow the EPA to dump contaminated soil from the Elizabeth River onto the 5-acre tract. The EPA would then clean up all the contamination and demolish seven structures on the property. The land would be sold once the four-year project is completed. Mensia-Joseph says the property was contaminated when the school district acquired it. A cleanup would cost the school district $3 million to $5 million.
