EPA Finalizes Clean Air Standards for Industrial Boilers, Incinerators and Cement Kilns

Friday, December 21st, 2012

On December 20th, the U.S. Environmental Protection Agency (EPA) finalized changes to Clean Air Act standards for boilers and certain incinerators that will achieve extensive public health protections by slashing toxic air pollution, including mercury and particle pollution, while at the same addressing feedback provided by industry and labor groups, increasing the rule’s flexibility and dramatically reducing costs. As a result, 99 percent of the approximately 1.5 million boilers in the U.S. are not covered or can meet the new standards by conducting periodic maintenance or regular tune-ups.

The final adjustments to the standards are based on an extensive analysis of data and input from states, environmental groups, industry, lawmakers and the public. As a result of information gathered through this review, including significant dialogue and meetings with public health groups, industry, and the public, the final rule dramatically cuts the cost of implementation by individual boilers that EPA proposed in 2010. At the same time, these rules will continue to deliver significant public health benefits. EPA estimates that for every dollar spent to reduce these pollutants, the public will see $13 to $29 in health benefits, including fewer instances of asthma, heart attacks, as well as premature deaths.

Today’s rules set numerical emission limits for less than one percent of boilers – those that emit the majority of pollution from this sector. For these high emitting boilers and incinerators, typically operating at refineries, chemical plants and other industrial facilities, EPA is establishing more targeted emissions limits that protect public health and provide industry with practical, cost-effective options to meet the standards.

EPA has also finalized revisions to the Non-Hazardous Secondary Materials Rule to provide clarity on what types of secondary materials are considered non-waste fuels and provide greater flexibility in rule implementation. This final rule classifies a number of secondary materials as categorical non-wastes when used as a fuel and allows for operators to request that EPA identify specific materials through rulemaking as a categorical non-waste fuel.

Particle pollution and other harmful pollutants released by boilers and incinerators can lead to adverse health effects including cancer, heart disease, aggravated asthma and premature death. In addition, toxic pollutants such as mercury and lead that will be reduced by this rule are linked to developmental disabilities in children. These standards will avoid up to 8,100 premature deaths, prevent 5,100 heart attacks and avert 52,000 asthma attacks per year in 2015.

In a separate EPA action today, to meet a court deadline, the agency issued final amendments to the 2010 clean air standards for the cement manufacturing industry. The final amendments maintain the significant emission reductions from the 2010 standards, while providing industry additional time to implement the revised rules.

EPA Sets First National Standard to Reduce Mercury Emissions from Gold Production

Friday, December 17th, 2010

WASHINGTON – The U.S. Environmental Protection Agency (EPA) is cutting emissions from gold ore processing and production facilities with a new standard that will reduce annual mercury emissions by more than 75 percent from 2007 levels.  This action is one of several steps EPA is taking to reduce mercury levels in our environment, which can damage children’s developing brains and nervous systems even before they are born.

EPA’s action sets the first national standard for mercury air emissions from industrial gold production, the seventh largest source of mercury air emissions in the country. Cuts made to meet the standard will build on the progress that has already been made under the state of Nevada’s successful program for controlling mercury emissions from precious metal mining.

 There are more than 20 facilities that extract gold from ore that will need to meet the requirements of the rule within three years.  Some facilities in Nevada already are making significant progress toward the federal requirements under that state’s program.

Portland Cement MACT: EPA Sets First National Limits to Reduce Mercury and Other Toxic Emissions from Cement Plants

Tuesday, August 10th, 2010

 WASHINGTON –The U.S. Environmental Protection Agency (EPA) is issuing final rules that will protect Americans’ health by cutting emissions of mercury, particle pollution and other harmful pollutants from Portland cement manufacturing, the third-largest source of mercury air emissions in the United States. The rules are expected to yield $7 to $19 in public health benefits for every dollar in costs. Mercury can damage children’s developing brains, and particle pollution is linked to a wide variety of serious health effects, including aggravated asthma, irregular heartbeat, heart attacks, and premature death in people with heart and lung disease.

“Americans throughout the country are suffering from the effects of pollutants in our air, especially our children who are more vulnerable to these chemicals,” EPA Administrator Lisa P. Jackson said. “This administration is committed to reducing pollution that is hurting the health of our communities.  With this historic step, we are going a long way in accomplishing that goal. By reducing harmful pollutants in the air we breathe, we cut the risk of asthma attacks and save lives.”

 This action sets the nation’s first limits on mercury air emissions from existing cement kilns, strengthens the limits for new kilns, and sets emission limits that will reduce acid gases. This final action also limits particle pollution from new and existing kilns, and sets new-kiln limits for particle and smog-forming nitrogen oxides and sulfur dioxide.

When fully implemented in 2013, EPA estimates the annual emissions will be reduced:

 Mercury – 16,600 pounds or 92 percent

  • Total hydrocarbons – 10,600 tons or 83 percent
  • Particulate Matter – 11,500 tons or 92 percent
  • Acid gases – (measured as hydrochloric acid): 5,800 tons or 97 percent
  • Sulfur dioxide (SO2)– 110,000 tons or 78 percent
  • Nitrogen oxides (NOx) – 6,600 tons or 5 percent

 Mercury in the air eventually deposits into water, where it changes into methylmercury, a highly toxic form that builds up in fish.  People are primarily exposed to mercury by eating contaminated fish. Because the developing fetus is the most sensitive to the toxic effects of methylmercury, women of childbearing age and children are regarded as the populations of greatest concern.

EPA estimates that the rules will yield $6.7 billion to $18 billion in health and environmental benefits, with costs estimated at $926 million to $950 million annually in 2013. Another EPA analysis estimates emission reductions and costs will be lower, with costs projected to be $350 million annually.
