The Labadie Energy Center and the Sioux Energy Center in Missouri will have two extra years to limit emissions of mercury and other hazardous air pollutants.

The bill has dozens of policy changes that affect how utility companies are allowed to operate and charge customers in Missouri.

Both Evergy and Ameren Missouri asked a Missouri House committee to support legislation that would allow them to charge customers for natural, or methane, gas power plants even before they’re completed, saying the state needs more electrical power.

Currently, Missouri utilities rely on audited past expenses — called a “test year” — to set rates. Critics say that allowing gas, water and sewer utilities to base rates on upcoming expenses would hurt customers.

The Environmental Protection Agency estimates Rush Island released 275,000 tons of sulfur dioxide after it was updated without required pollution controls in 2007 and 2010.

Evergy saw blowback from customers over time-of-use pricing, which places a premium on electricity at times of high demand. Under one of the plans, power used on summer days between 4 p.m. and 8 p.m. would be almost four times as expensive as the rest of the day. Now Evergy is requesting permission for customers to opt out.

The North Omaha Station, a coal burning power plant, was supposed to stop burning coal next year. But its owner wants an extension to keep burning coal for three more years.

Missouri environmental groups are decrying proposed state rules that would allow power plants to discharge contaminants like coal ash into groundwater through a general permit for multiple facilities. Power plants currently have individual, site-specific permits.

The coal ash basins at Labadie Energy Center contain 15 million cubic yards of waste, the largest volume of Ameren’s four coal-fired power plants in Missouri.

Of the nation's 10 coal-fired power plants that produce the most sulfur dioxide, four are located in the Midwest. And yet, none violate Environmental Protection Agency (EPA) standards.

Environmental advocates say water used for cooling Ameren’s Labadie Energy Center, along with toxic contaminants leaching from coal ash ponds, pose a risk to wildlife and the surrounding area.

Missouri's sole nuclear power plant is back online after being shut down for more than three weeks. Ameren Missouri's Callaway Energy Center was taken off
