The Missouri Department of Natural Resources is planning to install air monitors near two power plants that officials say are the largest sources of sulfur dioxide emissions in the state.
DNR is working on an agreement with Ameren Missouri to add sulfur dioxide monitors near two of the utility's plants. They are the Labadie plant in Franklin County and the Rush Island plant in Jefferson County.
But an environmental group that has long advocated for more monitoring data is concerned the plan could delay action to limit the pollutant, which can cause respiratory ailments like asthma. The St. Louis Post-Dispatch reports the Sierra Club worries that state officials may use the monitors to start a long, time-consuming process to collect and analyze data.
