The Sierra Club is appealing to Ameren shareholders in an attempt to prompt the utility to move away from coal-based energy.

The organization has submitted a resolution to shareholders calling for at least 30-percent wind and solar sourced energy by 2030 and at least 70-percent by 2050.

Updated 5:00 p.m., Sept. 24 with vote result - The Missouri Air Conservation Commission has voted to designate parts of Franklin and St. Charles counties as "unclassifiable" for sulfur dioxide pollution.

Thursday's vote follows a recommendation by the Missouri Department of Natural Resources earlier this week.

The Sierra Club says Ameren's Labadie power plant in Franklin County does not meet state and federal water quality standards and wants it brought into compliance.

On Friday, the environmental group filed an appeal with the state, alleging the plant’s operating permit does not do enough to protect wildlife or groundwater.

Coal has continued to fuel arguments over health hazards, hidden costs, and energy efficiency since “St. Louis on the Air” tackled Missouri’s problematic coal dependence in a July show featuring an ex-miner from Appalachia.

Ameren is not moving forward with plans for a second reactor at its Callaway Nuclear Power Plant in mid-Missouri near Fulton. Ameren's application for a second reactor at Callaway was filed with the Nuclear Regulatory Commission in 2008.  But funding issues hampered the project. State lawmakers have balked at the utility's efforts to allow Ameren to charge customers for the facility as it was being built.

During a conference call Friday morning with analysts, Chief Executive Officer Warner Baxter cited several reasons for the decision to pull the plug.

Updated 10 a.m. Tuesday with cost information from Ameren.

The U.S. Supreme Court has ruled against the Obama administration, saying the U.S. Environmental Protection Agency should have considered costs to industry when it set limits on mercury and other emissions from power plants.

The court's 5-to-4 decision was a victory for industry groups and more than 20 states — including Missouri — that had sued the EPA over its 2011 Mercury and Air Toxics Standards.

The Missouri Supreme Court has ruled that Ameren Missouri is not responsible for the deaths of two young children who drowned after being electrocuted on the Lake of the Ozarks.

Ameren owns the lake, which is part of its Osage power plant. Alexandra and Brayden Anderson were swimming in the lake on July 4, 2012, when they were shocked by a stray current from the family's dock and drowned. Their mother sued Ameren, saying the company regulated the installation of docks on the lake and was therefore liable for the deaths.

The coal ash landfill hearing got underway at 9 a.m. and lasted into the evening. Ameren employees wearing bright yellow vests attended the hearing in shifts throughout the day.

The chambers of the Franklin County Commission were filled to near capacity for much of the day on Thursday for a public hearing about proposed changes to the county’s coal ash landfill regulations.

The regulations will affect a coal ash landfill that Ameren wants to build next to its power plant in Labadie.

In April, Franklin County considered a proposal to ease its restrictions on coal ash landfills. Even though that meeting was open to the public, county residents were not allowed to speak. This Thursday they’ll get their chance.

The all-day hearing with county’s board of commissioners is the latest installment in a six-year battle over Ameren’s plans to build a coal ash landfill next to its power plant in Labadie.

The Missouri Coalition for the Environment filed a federal lawsuit Thursday over a federal agency’s renewal for Ameren’s Callaway Nuclear Power Plant.

Ameren is asking for more time and pitching an alternative plan to the Environmental Protection Agency's proposal to cut power plant carbon emissions by 30 percent by 2030.

The EPA's Clean Power Plan would require states to meet incremental goals starting in 2020, to measure progress toward the final target reduction.

There’s a new twist in the legal wrangling over Ameren’s plans to build a coal ash landfill in Franklin County.

On Tuesday, Ameren and Franklin County together filed a lawsuit against the Labadie Environmental Organization, a nonprofit made up of area residents opposing the landfill.

St. Louisans wishing to comment on the possibility of an increase in their electric bill will have two chances to speak with the Missouri agency that regulates investor-owned utilities Monday.

The Missouri Public Service Commission is holding a public hearing at noon at the Holiday Inn on Watson Road near Kirkwood and another at 6 p.m. at St. Louis Community College-Florissant Valley.

In Dec. 2008, a dike collapsed at TVA's coal-fired power plant near Kingston, Tenn., releasing 1.1 billion gallons of coal ash into the Emory and Clinch rivers and covering about 300 acres of land.

A local environmental group is asking state regulators to deny Ameren’s request to build a new coal ash landfill next to its Labadie power plant in Franklin County, on the basis that the landfill would not comply with new federal regulations.

Ameren Missouri officials say the utility will invest $135 million in a three-year energy efficiency plan to begin in 2016.  

Ameren filed the plan with the Missouri Public Service Commission Monday. The utility said it's expected to provide more than $260 million in customer benefits over 20 years.

Ameren’s director of energy efficiency, Dan Laurent, said the plan also is expected to save about 426,000 megawatt hours.

Ameren’s 2,400-megawatt plant near Labadie, Missouri, is the state’s largest coal-fired power plant. It produces an average of 550,000 tons of coal ash each year.

Updated 10/1/2014 to add comments.

Missouri is making headway toward developing a Comprehensive State Energy Plan Wednesday with the inaugural public meeting in St. Louis of the plan's steering committee.

Also on Wednesday, the state's largest electric energy provider, Ameren, released its energy plan for the next two decades.

As expected, the Missouri Public Service Commission has blocked the effort by Noranda Aluminum Inc. to get its electrical bill cut by about 25 percent.

Ameren contended that the cut would have forced rate hikes for most other Missouri customers in the state.

The Environmental Protection Agency's proposed Clean Power Plan will be a historic milestone in the vein of the 1970’s Clean Water and Clean Air acts.

That was Karl Brooks’ message to members of the St. Louis Regional Chamber at a breakfast event Wednesday morning. Brooks is the administrator of EPA’s Region 7, which includes Missouri, Iowa, Kansas and Nebraska.

The Clean Power Plan proposes cutting power plants' carbon emissions by 30 percent by the year 2030.

Updated 7/25/14 with information on a new lawsuit.

The Labadie Environmental Organization (LEO) has filed another lawsuit in their long-running campaign to prevent Ameren from building a coal ash landfill in Franklin County.
