Dear Congressman Meeks

Thank you for your letter of June 21, 2011, co-signed by 105 of your colleagues, to the U.S. Environmental Protection Agency in which you stated your support for the proposed "National Emission Standards for Hazardous Air Pollutants from Coal- and Oil-Fired Electric Utility Steam GeneratingUnits and Standards of Performance for Fossil-Fuel-Fired Electric Utility, Industrial-CommercialInstitutional, and Small Industrial-Commercial-Institutional Steam Generating Units" (the Mercury and Air Toxics Standards rule), which was published in the Federal Register on May 3, 2011. The Administrator asked that I respond on her behalf.

We sincerely appreciate your support for the proposed rule. The EPA remains committed to protecting public health as required by the Clean Air Act. By updating the public health safeguards to reduce mercury, acid gasses, and other life-threatening pollutants in our air, the EPA is protecting families from illness and premature deaths. Toxic air pollutants like mercury from coal- and oil-fired power plants can cause neurological damage, especially in young children, reducing their IQ and impairing their ability to learn. In addition to mercury, the proposed standards would also reduce emissions of other toxic metals like arsenic, chromium and nickel that are known or suspected carcinogens. These toxic pollutants contribute to fine particle pollution, which can cause premature death, and heart disease, aggravate asthma, and contribute to missed days of work and school due to illness.

Improved air quality from reduced power plant emissions would provide up to $140 billion annually in public health benefits. These benefits are especially important for minority and low-income populations that are disproportionately affected by asthma and other debilitating health conditions. The proposed standards would also keep people working and avoiding sick days while enhancing productivity, and creating thousands of high-quality American jobs. EPA estimates the proposed rule would support 31,000 short-term construction jobs and 9,000 long-term utility jobs as pollution control equipment is manufactured, installed, maintained, and operated on an ongoing basis.

The Honorable Shelley Berkley U.S. House of Representatives Washington, DC 20515

Dear Congresswoman Berkley:

Thank you for your letter of June 21, 2011, co-signed by 105 of your colleagues, to the U.S. Environmental Protection Agency in which you stated your support for the proposed "National Emission Standards for Hazardous Air Pollutants from Coal- and Oil-Fired Electric Utility Steam GeneratingUnits and Standards of Performance for Fossil-Fuel-Fired Electric Utility, Industrial-CommercialInstitutional, and Small Industrial-Commercial-Institutional Steam Generating Units" (the Mercury and Air Toxics Standards rule), which was published in the Federal Register on May 3, 2011. The Administrator asked that I respond on her behalf.

We sincerely appreciate your support for the proposed rule. The EPA remains committed to protecting public health as required by the Clean Air Act. By updating the public health safeguards to reduce mercury, acid gasses, and other life-threatening pollutants in our air, the EPA is protecting families from illness and premature deaths. Toxic air pollutants like mercury from coal- and oil-fired power plants can cause neurological damage, especially in young children, reducing their IQ and impairing their ability to learn. In addition to mercury, the proposed standards would also reduce emissions of other toxic metals like arsenic, chromium and nickel that are known or suspected carcinogens. These toxic pollutants contribute to fine particle pollution, which can cause premature death, and heart disease, aggravate asthma, and contribute to missed days of work and school due to illness.

Improved air quality from reduced power plant emissions would provide up to $140 billion annually in public health benefits. These benefits are especially important for minority and low-income populations that are disproportionately affected by asthma and other debilitating health conditions. The proposed standards would also keep people working and avoiding sick days while enhancing productivity, and creating thousands of high-quality American jobs. EPA estimates the proposed rule would support 31,000 short-term construction jobs and 9,000 long-term utility jobs as pollution control equipment is manufactured, installed, maintained, and operated on an ongoing basis.

The Honorable Louise M. Slaughter U.S. House of Representatives Washington, DC 20515

Dear Congresswoman Slaughter:

Thank you for your letter of June 21, 2011, co-signed by 105 of your colleagues, to the U.S. Environmental Protection Agency in which you stated your support for the proposed "National Emission Standards for Hazardous Air Pollutants from Coal- and Oil-Fired Electric Utility Steam GeneratingUnits and Standards of Performance for Fossil-Fuel-Fired Electric Utility, Industrial-CommercialInstitutional, and Small Industrial-Commercial-Institutional Steam Generating Units" (the Mercury and Air Toxics Standards rule), which was published in the Federal Register on May 3, 2011. The Administrator asked that I respond on her behalf

We sincerely appreciate your support for the proposed rule. The EPA remains committed to protecting public health as required by the Clean Air Act. By updating the public health safeguards to reduce mercury, acid gasses, and other life-threatening pollutants in our air, the EPA is protecting families from illness and premature deaths. Toxic air pollutants like mercury from coal- and oil-fired power plants can cause neurological damage, especially in young children, reducing their IQ and impairing their ability to learn. In addition to mercury, the proposed standards would also reduce emissions of other toxic metals like arsenic, chromium and nickel that are known or suspected carcinogens. These toxic pollutants contribute to fine particle pollution, which can cause premature death, and heart disease, aggravate asthma, and contribute to missed days of work and school due to illness.

Improved air quality from reduced power plant emissions would provide up to $140 billion annually in public health benefits. These benefits are especially important for minority and low-income populations that are disproportionately affected by asthma and other debilitating health conditions. The proposed standards would also keep people working and avoiding sick days while enhancing productivity, and creating thousands of high-quality American jobs. EPA estimates the proposed rule would support 31,000 short-term construction jobs and 9,000 long-term utility jobs as pollution control equipment is manufactured, installed, maintained, and operated on an ongoing basis.

Dear Congresswoman Hanabusa:

Thank you for your letter of June 21, 2011, co-signed by 105 of your colleagues, to the U.S. Environmental Protection Agency in which you stated your support for the proposed "National Emission Standards for Hazardous Air Pollutants from Coal- and Oil-Fired Electric Utility Steam GeneratingUnits and Standards of Performance for Fossil-Fuel-Fired Electric Utility, Industrial-CommercialInstitutional, and Small Industrial-Commercial-Institutional Steam Generating Units" (the Mercury and Air Toxics Standards rule), which was published in the Federal Register on May 3, 2011. The Administrator asked that I respond on her behalf.

We sincerely appreciate your support for the proposed rule. The EPA remains committed to protecting public health as required by the Clean Air Act. By updating the public health safeguards to reduce mercury, acid gasses, and other life-threatening pollutants in our air, the EPA is protecting families from illness and premature deaths. Toxic air pollutants like mercury from coal- and oil-fired power plants can cause neurological damage, especially in young children, reducing their IQ and impairing their ability to learn. In addition to mercury, the proposed standards would also reduce emissions of other toxic metals like arsenic, chromium and nickel that are known or suspected carcinogens. These toxic pollutants contribute to fine particle pollution, which can cause premature death, and heart disease, aggravate asthma, and contribute to missed days of work and school due to illness.

Improved air quality from reduced power plant emissions would provide up to $140 billion annually in public health benefits. These benefits are especially important for minority and low-income populations that are disproportionately affected by asthma and other debilitating health conditions. The proposed standards would also keep people working and avoiding sick days while enhancing productivity, and creating thousands of high-quality American jobs. EPA estimates the proposed rule would support 31,000 short-term construction jobs and 9,000 long-term utility jobs as pollution control equipment is manufactured, installed, maintained, and operated on an ongoing basis.

The proposed standards would also keep people working and avoiding sick days while enhancing productivity, and creating thousands of high-quality American jobs. EPA estimates the proposed rule would support 31,000 short-term construction jobs and 9,000 long-term utility jobs as pollution control equipment is manufactured, installed, maintained, and operated on an ongoing basis.

Dear Congressman Grijalva:

Thank you for your letter of June 21, 2011, co-signed by 105 of your colleagues, to the U.S. Environmental Protection Agency in which you stated your support for the proposed "National Emission Standards for Hazardous Air Pollutants from Coal- and Oil-Fired Electric Utility Steam GeneratingUnits and Standards of Performance for Fossil-Fuel-Fired Electric Utility, Industrial-CommercialInstitutional, and Small Industrial-Commercial-Institutional Steam Generating Units" (the Mercury and Air Toxics Standards rule), which was published in the Federal Register on May 3, 2011. The Administrator asked that I respond on her behalf.

We sincerely appreciate your support for the proposed rule. The EPA remains committed to protecting public health as required by the Clean Air Act. By updating the public health safeguards to reduce mercury, acid gasses, and other life-threatening pollutants in our air, the EPA is protecting families from illness and premature deaths. Toxic air pollutants like mercury from coal- and oil-fired power plants can cause neurological damage, especially in young children, reducing their IQ and impairing their ability to learn. In addition to mercury, the proposed standards would also reduce emissions of other toxic metals like arsenic, chromium and nickel that are known or suspected carcinogens. These toxic pollutants contribute to fine particle pollution, which can cause premature death, and heart disease, aggravate asthma, and contribute to missed days of work and school due to illness.

Dear Congressman Michaud:

Thank you for your letter of June 21, 2011, co-signed by 105 of your colleagues, to the U.S. Environmental Protection Agency in which you stated your support for the proposed "National Emission Standards for Hazardous Air Pollutants from Coal- and Oil-Fired Electric Utility Steam GeneratingUnits and Standards of Performance for Fossil-Fuel-Fired Electric Utility, Industrial-CommercialInstitutional, and Small Industrial-Commercial-Institutional Steam Generating Units" (the Mercury and Air Toxics Standards rule), which was published in the Federal Register on May 3, 2011. The Administrator asked that I respond on her behalf

We sincerely appreciate your support for the proposed rule. The EPA remains committed to protecting public health as required by the Clean Air Act. By updating the public health safeguards to reduce mercury, acid gasses, and other life-threatening pollutants in our air, the EPA is protecting families from illness and premature deaths. Toxic air pollutants like mercury from coal- and oil-fired power plants can cause neurological damage, especially in young children, reducing their IQ and impairing their ability to learn. In addition to mercury, the proposed standards would also reduce emissions of other toxic metals like arsenic, chromium and nickel that are known or suspected carcinogens. These toxic pollutants contribute to fine particle pollution, which can cause premature death, and heart disease, aggravate asthma, and contribute to missed days of work and school due to illness.

Improved air quality from reduced power plant emissions would provide up to $140 billion annually in public health benefits. These benefits are especially important for minority and low-income populations that are disproportionately affected by asthma and other debilitating health conditions. The proposed standards would also keep people working and avoiding sick days while enhancing productivity, and creating thousands of high-quality American jobs. EPA estimates the proposed rule would support 31,000 short-term construction jobs and 9,000 long-term utility jobs as pollution control equipment is manufactured, installed, maintained, and operated on an ongoing basis.

Dear Congressman Frank:

Thank you for your letter of June 21, 2011, co-signed by 105 of your colleagues, to the U.S. Environmental Protection Agency in which you stated your support for the proposed "National Emission Standards for Hazardous Air Pollutants from Coal- and Oil-Fired Electric Utility Steam GeneratingUnits and Standards of Performance for Fossil-Fuel-Fired Electric Utility, Industrial-CommercialInstitutional, and Small Industrial-Commercial-Institutional Steam Generating Units" (the Mercury and Air Toxics Standards rule), which was published in the Federal Register on May 3, 2011. The Administrator asked that I respond on her behalf

We sincerely appreciate your support for the proposed rule. The EPA remains committed to protecting public health as required by the Clean Air Act. By updating the public health safeguards to reduce mercury, acid gasses, and other life-threatening pollutants in our air, the EPA is protecting families from illness and premature deaths. Toxic air pollutants like mercury from coal- and oil-fired power plants can cause neurological damage, especially in young children, reducing their IQ and impairing their ability to learn. In addition to mercury, the proposed standards would also reduce emissions of other toxic metals like arsenic, chromium and nickel that are known or suspected carcinogens. These toxic pollutants contribute to fine particle pollution, which can cause premature death, and heart disease, aggravate asthma, and contribute to missed days of work and school due to illness.

Improved air quality from reduced power plant emissions would provide up to $140 billion annually in public health benefits. These benefits are especially important for minority and low-income populations that are disproportionately affected by asthma and other debilitating health conditions. The proposed standards would also keep people working and avoiding sick days while enhancing productivity, and creating thousands of high-quality American jobs. EPA estimates the proposed rule would support 31,000 short-term construction jobs and 9,000 long-term utility jobs as pollution control equipment is manufactured, installed, maintained, and operated on an ongoing basis.

These benefits are especially important for minority and low-income populations that are disproportionately affected by asthma and other debilitating health conditions. The proposed standards would also keep people working and avoiding sick days while enhancing productivity, and creating thousands of high-quality American jobs. EPA estimates the proposed rule would support 31,000 short-term construction jobs and 9,000 long-term utility jobs as pollution control equipment is manufactured, installed, maintained, and operated on an ongoing basis.

Dear Congressman Holt:

Thank you for your letter of June 21, 2011, co-signed by 105 of your colleagues, to the U.S. Environmental Protection Agency in which you stated your support for the proposed "National Emission Standards for Hazardous Air Pollutants from Coal- and Oil-Fired Electric Utility Steam GeneratingUnits and Standards of Performance for Fossil-Fuel-Fired Electric Utility, Industrial-CommercialInstitutional, and Small Industrial-Commercial-Institutional Steam Generating Units" (the Mercury and Air Toxics Standards rule), which was published in the Federal Register on May 3, 2011. The Administrator asked that I respond on her behalf.

We sincerely appreciate your support for the proposed rule. The EPA remains committed to protecting public health as required by the Clean Air Act. By updating the public health safeguards to reduce mercury, acid gasses, and other life-threatening pollutants in our air, the EPA is protecting families from illness and premature deaths. Toxic air pollutants like mercury from coal- and oil-fired power plants can cause neurological damage, especially in young children, reducing their IQ and impairing their ability to learn. In addition to mercury, the proposed standards would also reduce emissions of other toxic metals like arsenic, chromium and nickel that are known or suspected carcinogens. These toxic pollutants contribute to fine particle pollution, which can cause premature death, and heart disease, aggravate asthma, and contribute to missed days of work and school due to illness.

Improved air quality from reduced power plant emissions would provide up to $140 billion annually in public health benefits.

EPA estimates the proposed rule would support 31,000 short-term construction jobs and 9,000 long-term utility jobs as pollution control equipment is manufactured, installed, maintained, and operated on an ongoing basis.

The Honorable Debbie Schultz U.S. House of Representatives Washington, DC 20515

Dear Congresswoman Schultz:

Thank you for your letter of June 21, 2011, co-signed by 105 of your colleagues, to the U.S. Environmental Protection Agency in which you stated your support for the proposed "National Emission Standards for Hazardous Air Pollutants from Coal- and Oil-Fired Electric Utility Steam GeneratingUnits and Standards of Performance for Fossil-Fuel-Fired Electric Utility, Industrial-CommercialInstitutional, and Small Industrial-Commercial-Institutional Steam Generating Units" (the Mercury and Air Toxics Standards rule), which was published in the Federal Register on May 3, 2011. The Administrator asked that I respond on her behalf.

We sincerely appreciate your support for the proposed rule. The EPA remains committed to protecting public health as required by the Clean Air Act. By updating the public health safeguards to reduce mercury, acid gasses, and other life-threatening pollutants in our air, the EPA is protecting families from illness and premature deaths. Toxic air pollutants like mercury from coal- and oil-fired power plants can cause neurological damage, especially in young children, reducing their IQ and impairing their ability to learn. In addition to mercury, the proposed standards would also reduce emissions of other toxic metals like arsenic, chromium and nickel that are known or suspected carcinogens. These toxic pollutants contribute to fine particle pollution, which can cause premature death, and heart disease, aggravate asthma, and contribute to missed days of work and school due to illness.

Improved air quality from reduced power plant emissions would provide up to $140 billion annually in public health benefits. These benefits are especially important for minority and low-income populations that are disproportionately affected by asthma and other debilitating health conditions. The proposed standards would also keep people working and avoiding sick days while enhancing productivity, and creating thousands of high-quality American jobs. EPA estimates the proposed rule would support 31,000 short-term construction jobs and 9,000 long-term utility jobs as pollution control equipment is manufactured, installed, maintained, and operated on an ongoing basis.
