After six years of building demolitions and excavations, workers have finished cleaning up the Carter Carburetor Superfund site in north St. Louis. 

The site, the former location of an oil and diesel carburetor manufacturing plant, closed in 1984. Nearly a decade later, the Environmental Protection Agency included it in the federal Superfund program, which investigates and cleans up hazardous waste sites. It left behind high levels of heavy metals and toxic chemicals, like PCBs, that are known to cause cancer.

The Metropolitan St. Louis Sewer District is building a three-mile sewer line underneath the city of Ladue to address overflow problems in the area.

The $62.5 million project, which began in September, is being constructed along Deer Creek in St. Louis County. The work will help the utility comply with a $4.7 billion consent decree from a 2012 Clean Water Act lawsuit

Workers are building a 2.6-mile trunk sewer to help prevent sewer overflows when it rains, said Rebecca Losli, a program manager for MSD.

A federal judge on Monday ordered Ameren Missouri to install devices at its power plants in Festus and Labadie to remove harmful air pollutants. 

U.S. District Judge Rodney Sippel ruled that Ameren has 90 days to apply for a Clean Air Act permit from the Missouri Department of Natural Resources to install scrubbers at the Rush Island Energy Center in Festus.

Missouri Mining Inc. plans to create up to 700 jobs by reopening a mine at a Superfund site in Fredericktown, Missouri. 

The company wants to extract cobalt from the Madison Mine, which it purchased last year. The mine has been inactive since the 1960s and is a part of the Madison County Mines Superfund site, an area contaminated by historic lead mining. 

Environmental Operations, a Missouri Mining subsidiary, plans to begin cleaning up the site this winter. Missouri Cobalt, another Missouri Mining subsidiary, could hire as many as 400 temporary workers and 250 permanent workers to rebuild and operate the mine.

People who live near the West Lake Landfill want to know how they will be protected from exposure to radiation when the Environmental Protection Agency begins removing nuclear contamination from the Superfund site in three years.

At a meeting late Thursday, EPA officials sought to assure residents they would be protected during the excavation. The federal agency last fall decided it would remove 70% of the site’s radioactivity.

Several residents said that they would like to be relocated while the waste is being removed.

The Environmental Protection Agency is allowing Veolia North America-Trade Waste Incineration, a facility in Sauget that runs a hazardous waste incinerator, to relax heavy-metal emissions monitoring, local environmentalists say.

A new permit issued by the EPA, which goes into effect on July 18, requires Veolia to install and operate mercury emissions controls on two incinerators that previously did not have mercury controls. The facility accepts waste such as propellants and explosives, reactive metals and poisonous materials for disposal, according to the company’s website.

The Missouri Department of Natural Resources has scrapped its proposal to regulate disposal sites for coal-fired power plants, a plan that environmentalists and federal regulators heavily criticized.

The plan would have required utilities monitor groundwater and clean up contamination near ponds and landfills that store byproducts of coal combustion, which contain toxic chemicals like mercury, arsenic and lead. Environmental groups, residents near power plants and the Environmental Protection agency wrote letters to the state agency earlier this year saying that the plan won’t address groundwater contamination.

DNR officials chose not to submit the proposed regulations to the Environmental Protection Agency because the federal agency did not give clear guidance on enforcing cleanup at the sites, said Chris Nagel, DNR’s solid waste director.

The Environmental Protection Agency has decided to conduct additional tests for radioactive contamination at the West Lake Landfill, which would delay its excavation of the Superfund site.

When the EPA region that oversees Missouri released its final plan last September to remove 70% of the radioactivity at the site, officials said the cleanup would begin after they spent 18 months planning how to remove the World War II-era waste.

EPA officials announced this week that parties responsible for the landfill signed an agreement with the agency to design the excavation plan. Because of the additional testing, the cleanup won’t begin for two and a half years, EPA spokesperson Ben Washburn said.

The Environmental Protection Agency notified Missouri environmental regulators this month that the state’s plan for overseeing the disposal of toxic waste from coal-fired power plants is not strong enough to protect human health and the environment.

In a recent letter to the Missouri Department of Natural Resources, EPA officials noted several provisions in the state’s plan that are weaker than the 2015 federal coal ash rule. Some allow the Missouri Department of Natural Resources to waive requirements for utility companies to clean up groundwater contamination or even monitor groundwater for toxic chemicals if they can show that it doesn’t affect drinking-water supplies or harm the environment.

Every Missouri utility that’s dumping waste from coal-fired power plants into massive pits in the ground has posted data that shows significant levels of nearby groundwater contamination, according to an analysis by the Washington University Interdisciplinary Environmental Clinic.

Missouri has never regulated these pits, known as coal ash ponds, even though they’ve existed for more than 50 years.

Bridgeton Landfill LLC and other companies responsible for cleaning up the West Lake Landfill are developing a plan to study radioactive contamination in groundwater at the site.

Federal officials and community members became concerned about groundwater contamination especially after the U.S. Geological Survey released a report in 2014 that found high levels of radium in samples taken from wells at the landfill. But at the time, scientists could not conclude that it was caused by the radioactive waste at the site.

Republic Services subsidiaries Bridgeton Landfill and Rock Road Industries, the Cotter Corporation, and the U.S. Department of Energy have until June 6 to submit a plan to the Environmental Protection Agency for how they will study the groundwater.

The Environmental Protection Agency is considering making changes to its 2012 mercury standards, which were responsible for major improvements to Missouri’s air quality in recent years.

In 2011, a report from Environment America showed that Missouri was one of the top mercury-polluting states in the country. Since then, mercury emissions in the state have dropped by more than 75 percent.

The EPA’s mercury regulations are largely responsible for that major drop in emissions of the toxic metal. Utility companies installed pollution-control equipment at coal-fired power plants in order to comply with strict federal standards. However, the federal agency last week announced that it’s proposing to revise the rule, based on its conclusion that it’s too costly for the coal industry.

Dicamba, the controversial herbicide used on soybeans and cotton, is responsible for thousands of acres of damaged crops in recent years.

Experts say that despite new federal rules that go into effect in 2019, the drift will continue but the victims will be different.

The Environmental Protection Agency is giving the Metropolitan St. Louis Sewer District a $48 million loan to build pump stations and sewers to help divert stormwater runoff in St. Louis County.

The federal loan funds nearly half of the $97 million cost to construct the series of wastewater projects that will be connected to the Deer Creek Sanitary Tunnel. The 4-mile underground tunnel, which would run through Webster Groves, Brentwood, Richmond Heights and other nearby municipalities, is designed to collect and separate wastewater from sewage. MSD began building the tunnel earlier this year.

The Environmental Protection Agency is looking to remove thousands of acres of wetlands and miles of waterways from Clean Water Act protections.

The EPA said Tuesday it believes the proposed changes to the “Waters of the United States” rule will reduce inefficiencies and allow landowners to have the freedom they need over their property.

The city of St. Louis and the U.S. Geological Survey this month are starting a study to determine if filling demolition sites with clean soil instead of building materials can help address one of St. Louis’ biggest environmental problems: sewage overflows.

Typically, contractors working for the city fill the basement with concrete and other materials from the demolished building. In north St. Louis, they recently began filling some basements with soil that’s been tested for environmental toxins. City and federal officials want to compare how well the two methods can absorb stormwater runoff.

The Environmental Protection Agency has finalized its plan to remove radioactive waste from the West Lake Landfill Superfund site.

The $205 million plan intends to remove about 70 percent of the site’s radioactivity and dispose of the waste at an out-of-state facility. The EPA will spend the next year and a half determining how to clean up the site and how to keep workers and the area residents safe during excavation.

Updated at 12:10 p.m. Sept. 28 — The Environmental Protection Agency has finalized its plan to remove radioactive waste from the West Lake Landfill Superfund site.

The chosen solution will remove about 70 percent of the site’s radioactivity and dispose of the waste at an out-of-state facility. The $205 million plan is similar, though less expensive, to what officials proposed in February.

On Thursday, the Environmental Protection Agency approved plans to clean up radioactive waste at the West Lake Landfill Superfund site.

The agency plans to remove about 70 percent of the site’s radioactivity and dispose of the waste at an off-site facility. The entire process is estimated to cost $205 million and take about four and a half years to complete.

The Environmental Protection Agency has changed its regulations to give states more authority over how utilities should dispose and monitor pollution from toxic waste generated by coal-fired power plants. Environmental advocates in Missouri and Illinois warn that the newly revised rule will not do enough to protect water quality and human health.

The amendments, approved Tuesday by acting EPA administrator Andrew Wheeler, lowered standards for several chemicals, such as lead, that are found in coal-ash waste. It also extends the deadline for utilities to close its coal-ash ponds and allows state officials to oversee and stop groundwater monitoring at coal-ash waste sites.

Just before former Gov. Eric Greitens resigned, he signed a bill to regulate coal-ash waste, a toxic byproduct of coal-fired power plants.

Coal ash, also known as coal combustion residuals, contains a number of heavy metals, including lead and arsenic, that are known to cause cancer. While some of the waste does become recycled, Ameren Missouri and other utilities dispose coal ash into landfills and ponds.

The head of the Environmental Protection Agency’s Superfund Task Force resigned Tuesday after one year in the role, leaving residents in northwest St. Louis County unsure about the fate of a proposal to clean up West Lake Landfill.

Albert Kelly, former EPA senior advisor, did not immediately return a call for comment. Media reports say the ex-banking executive resigned after relentless bad press about his financial dealings. Before he joined the EPA, Kelly helped administrator Scott Pruitt get financing to pay for a mortgage and to buy a minor league baseball team. Later, the Federal Deposit Insurance Corp. banned Kelly from the industry because of a previous banking violation.

As environmentalists voiced concerns in Washington about possible changes to the Environmental Protection Agency's rules on disposing coal ash waste, some in Missouri chose to express their opposition by staging a protest at a major utility corporation's doorstep. 

The Missouri chapter of the Sierra Club gathered a small band of supporters Tuesday at Ameren Missouri's headquarters in St. Louis. They held large signs that showed images of Ameren's four power plants in Missouri and listed details about the toxic heavy metals that coal ash contains, such as arsenic.

Ameren Missouri announced recently that it plans to close all of its coal ash ponds by 2022. However, activists want the regulators to address the contamination the ponds have already caused and are unhappy that Ameren has chosen to close its ponds by leaving them in place.

On a bright, brisk winter day in Branson, Mo., several dedicated fishermen tried to catch trout in Lake Taneycomo, a fast-moving, ribbon-shaped lake that snakes around the city.

The water appeared clear, but the lake has some ongoing issues, said David Casaletto, executive director of Ozarks Water Watch, a water quality group. For example, heavy rains in the summer have caused low levels of dissolved oxygen, which has hurt the trout population.

Under a recently proposed water quality rule from the Environmental Protection Agency, Lake Taneycomo, Mark Twain Lake and Lake of the Ozarks are among 113 lakes and reservoirs in Missouri that would be defined as “impaired” or too polluted for human use.

Updated on March 5 to note new deadline for public comments  — The Environmental Protection Agency has released its plan for cleaning up radioactive waste at West Lake Landfill.

But officials say they still want to hear from community members on all the proposed remedies, not just the one the agency selected.

The EPA asked for feedback on three elements of its plan: Does the EPA’s proposed excavation plan address public concerns regarding the thoroughness of the removal? How should excavation differ between waste areas? And, where should the radioactive material go after it’s removed? Access all the plan’s documents on the EPA’s website.
