The Dubuque City Council voted, 7-0, at a special meeting this week to replace the engineering consultant it hires to manage EPA grants earmarked for polluted brownfield mitigation. Impact 7G, an Iowa firm, will take over the work from Blackstone Environmental of Missouri. The council authorized city staff to negotiate the precise contract which will be worth about $200,000, paid out from the $800,000 EPA grant. The city of Dubuque won the brownfields cleanup grant in 2019, but the COVID-19 pandemic delayed the cleanup, and the EPA did not approve a work plan until 2021. Three specific sites are intended to be cleaned up with this grant — an eastern expansion of Comiskey Park on the North End and two polluted areas at the South Port — an old Sinclair Oil terminal and Dodd’s Terminal.
