On October 22, 2019, the U.S. District Court for the Eastern District of Missouri partially stayed its remedy decision in United States v. Ameren Missouri pending Ameren’s appeal. Ameren had requested that the report stay its entire remedy decision pending appeal to the Eighth Circuit. The court declined, but did grant Ameren partial relief. Under the partial stay, Ameren must continue to prepare and submit a PSD permit application to the Missouri Department of Natural Resources, including the request for wet flue gas desulfurization as BACT, but is not required to begin construction until the Eighth Circuit appeal is completed.
