The Sierra Club says Ameren has been routinely violating air quality standards at its St. Louis-area power plants.

In a Notice of Intent to Sue delivered to Ameren on Wednesday afternoon, the Sierra Club alleges the company's Labadie, Meramec, and Rush Island plants have exceeded air pollution limits almost 10,000 times since 2008.

The Environmental Protection Agency is holding a public hearing Thursday evening about a proposed agreement to address water pollution from the illegal disposal of coal ash from Ameren’s Rush Island Power Plant.

According to the EPA, approximately 140,000 tons of ash containing heavy metals and other toxic substances contaminated Jefferson County wetlands, an unnamed tributary to Plattin Creek and a portion of Willers Lake.

Environmental groups are once again urging state officials to require groundwater monitoring at Ameren’s coal-fired power plants in eastern Missouri.

The Sierra Club and Labadie Environmental Organization submitted a letter to the Missouri Department of Natural Resources on Thursday asking the state not to allow Ameren to build new coal ash landfills before testing groundwater for contamination.

Original story posted 5:53 p.m. Aug. 7, 2012:

The St. Louis-based utility company Ameren is proposing to build a coal ash landfill at its Rush Island power plant in Jefferson County, about 10 miles southeast of Festus.

The Missouri Department of Natural Resources is holding a public awareness session tonight to describe the permitting process for the landfill.

Ameren Missouri is asking a federal judge to dismiss a lawsuit filed against the company by the US Environmental Protection Agency.

The suit filed in January alleges that Ameren violated the Clean Air Act by making multi-million-dollar modifications to its coal-fired power plant in Festus without installing required pollution controls and obtaining the necessary permits.
