EPA Proposes to Reduce Toxic Pollutants Discharged into Waterways by Power Plants

WASHINGTON — In accordance with a consent decree and in line with requirements under the Clean Water Act, the U.S. Environmental Protection Agency (EPA) today will propose a range of options to help reduce dangerous pollutants, including mercury, arsenic, lead, and selenium that are released into America’s waterways by coal ash, air pollution control waste and other waste from steam electric power plants. Today’s proposal includes a variety of options for whether and how these different waste streams should be treated. EPA will take comment on all of these options, which it will use to help inform the most appropriate final standard.

Steam electric power plants currently account for more than half of all toxic pollutants discharged into streams, rivers and lakes from permitted industrial facilities in the United States. High exposure to these types of pollutants has been linked to neurological damage and cancer as well as damage to the circulatory system, kidneys and liver.Toxic heavy metals do not break down in the environment and can also contaminate sediment in waterways and impact aquatic life and wildlife, including large-scale die-offs of fish.

"America’s waterways are vital to the health and well-being of our communities," said Acting Administrator Bob Perciasepe. "Reducing the pollution of our waters through effective but flexible controls such as we are proposing today is a win-win for our public health and our economic vitality. We look forward to hearing from all stakeholders on the best way forward."

EPA has put a focus on ensuring any final rule would protect public health while being sensible and achievable, and in line with that goal, under every preferred option proposed by EPA today, more than half of America’s coal fired power plants would be in compliance without incurring any additional cost.

The proposal updates standards that have been in place since 1982, incorporating technology improvements in the steam electric power industry over the last three decades as required by the Clean Water Act. The proposed national standards are based on data collected from industry and provide flexibility in implementation through a phased-in approach and use of technologies already installed at a number of plants. Under the proposed approach, new requirements for existing power plants would be phased in between 2017 and 2022, and would leverage flexibilities as necessary.

Fewer than half of coal-fired power plants are estimated to incur costs under any of the proposed preferred options, because many power plants already have the technology and procedures in place to meet the proposed pollution control standards.

The four preferred options differ in the number of waste streams covered (such as fly ash handling systems, treatment of air pollution control waste and bottom ash), the size of the units controlled and the stringency of the treatment controls to be imposed. EPA estimates that the regulations would reduce pollutant discharges by 470 million to 2.62 billion pounds annually and reduce water use by 50 billion to 103 billion gallons per year.

EPA also announced its intention to align this Clean Water Act rule with a related rule for coal combustion residuals (CCRs, also known as "coal ash") proposed in 2010 under the Resource Conservation and Recovery Act. The two rules would apply to many of the same facilities and would work together to reduce pollution associated with coal ash and related wastes. EPA is seeking comment from industry and other stakeholders to ensure that both final rules are aligned to reduce pollution efficiently and minimize regulatory burdens.

There are approximately 1,200 steam electric power plants that generate electricity using nuclear fuel or fossil fuels such as coal, oil, and natural gas in the U.S. Approximately 500 of these power plants are coal fired units which are the primary source of the pollutants being addressed by the proposed regulation. Power plants that are smaller than 50 megawatts would not be impacted by these new standards, and the majority of coal-fired power plants would incur no costs under the proposed standards.

The public comment period on the proposed rule will be open for 60 days after publication in the Federal Register. The agency is under a consent decree to take final action by May 22, 2014.

EPA ISSUES UPDATES ON NEW POWER PLANT MERCURY AND AIR TOXICS STANDARDS

EPA Updates Mercury and Air Toxics Standards for New Power Plants

Agency also proposes updates to oil and gas storage tank standards

WASHINGTON -- The U.S. Environmental Protection Agency (EPA) has issued updates to pollution limits for new power plants under the mercury and air toxics standards, based on new information and analysis that became available to the agency after the rule was finalized.

The updates are largely technical in nature and will have no impact on the sensible, achievable and cost-effective standards already set for existing power plants. The public health benefits and costs of the rule remain unchanged. EPA estimates that the standards, which will protect the health of millions of families, especially children, will prevent as many as 11,000 premature deaths and 4,700 heart attacks every year. The standards will also help America’s children grow up healthier-- preventing 130,000 cases of childhood asthma symptoms and about 6,300 fewer cases of acute bronchitis among children each year.

The updated standards only apply to future power plants and do not change the types of pollution control technology that plants would install. The updates ensure that emissions limits are achievable and that pollution levels can be measured continuously.

EPA’s mercury and air toxics standards are the first national standards to protect American families from power plant emissions of mercury and toxic air pollution like arsenic, acid gas, nickel, selenium and cyanide. EPA considered dozens of public comments from a range of stakeholders, including industry and environmental groups, as part of the public process to update the new source standards.

Also on March 28, 2013, EPA proposed updates to the agency’s 2012 performance standards for storage tanks used in oil and natural gas production. The proposed changes reflect recent information showing that more higher-volume storage tanks will be coming on line than the agency originally estimated and would provide storage tank owners and operators additional time to comply with a requirement to reduce volatile organic compound emissions while equipment to reduce those emissions is being manufactured. EPA will take comment on today’s proposal for 30 days after it is published in the Federal Register and will hold a public hearing if requested.
