The Honorable Gregory W. Meeks

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 Generating 

Units 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.

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 Engel 

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 Generating 

Units 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

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 1-leinrich: 

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 Generating 

Units 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.

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 Peter Welch 

U.S. House of Representatives 

Washington, DC 20515 

Dear Congressman Welch: 

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 Generating 

Units 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

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 Charles B. Rangel

Washington, DC 20515 

Dear Congressman Rangel 

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 Generating 

Units 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 McDermott: 

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 Generating 

Units 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.

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.

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 Generating 

Units 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.
