Mar 20, 2012 Administrator Dennis McLerran EPA Region 10, 1200 Sixth Avenue, Suite 900 Seattle, WA 98101 Dear Administrator McLerran, I urge you to strengthen Alaska's regional haze plan. Clean and clear air in Denali National Park and Preserve is important to me. Unfortunately, one industrial facility, Healy Units 1 and 2, is less than five miles from Denali, and is not being required to clean up enough to significantly decrease its impact on the park. Please improve your proposal and require greater pollution reductions from these park polluters. As a national park visitor and advocate for the parks, I value Denali's pristine air and breathtaking views. Unfortunately, EPA has approved an Alaska haze plan that will not adequately protect the places that I care deeply about. For Healy Unit 1, an older power plant, modern controls should be required to stem the haze pollution that currently threatens Denali's majestic lands. For Healy Unit 2, a newer facility, no pollution controls were proposed. This plan would allow the Healy Unit 2 to operate for five years or more, next door to Denali, without being evaluated for modern, haze-limiting controls. I ask that EPA require modern and effective pollution controls to mitigate haze before this facility restarts operations. Reduced views and compromised air quality are problems that Congress sought to fix by setting aside these lands for special air quality protection. And we need to fix these problems. The EPA cannot let Alaska power plants escape pollution controls; please require an adequate Alaska haze plan that would ensure clean air in Denali, and throughout the region for present and future generations. Thank you for considering my request. Sincerely,Mr. Robert Harrison 40374 Waterman Rd Homer, AK 99603-9404

Mar 20, 2012 Administrator Dennis McLerran EPA Region 10, 1200 Sixth Avenue, Suite 900 Seattle, WA 98101 Dear Administrator McLerran, I have been enjoying Denali's clear and awe-inspiring views of Mt.McKinley for almost 30 years. While Denali's air is very clean, air pollution problems in the lower 48 (like at Great Smoky Mountains national park) began with just one power plant. The purpose of the Clean Air Act is to protect our nation's air quality, especially at special places like Denali - the only national park in Alaska classified as a Class 1 area. I urge you to strengthen Alaska's regional haze plan. Clean and clear air in Denali National Park and Preserve is important to me. Unfortunately, one industrial facility, Healy Units 1 and 2, is less than five miles from Denali, and is not being required to clean up enough to significantly decrease its impact on the park.

Mar 20, 2012 Administrator Dennis McLerran EPA Region 10, 1200 Sixth Avenue, Suite 900 Seattle, WA 98101 Dear Administrator McLerran, I urge you to strengthen Alaska's regional haze plan. Clean and clear air in Denali National Park and Preserve is important to me. Unfortunately, one industrial facility, Healy Units 1 and 2, is less than five miles from Denali, and is not being required to clean up enough to significantly decrease its impact on the park. Please improve your proposal and require greater pollution reductions from these park polluters. As a national park visitor and advocate for the parks, I value Denali's pristine air and breathtaking views. Unfortunately, EPA has approved an Alaska haze plan that will not adequately protect the places that I care deeply about. For Healy Unit 1, an older power plant, modern controls should be required to stem the haze pollution that currently threatens Denali's majestic lands. For Healy Unit 2, a newer facility, no pollution controls were proposed. This plan would allow the Healy Unit 2 to operate for five years or more, next door to Denali, without being evaluated for modern, haze-limiting controls. I ask that EPA require modern and effective pollution controls to mitigate haze before this facility restarts operations. Reduced views and compromised air quality are problems that Congress sought to fix by setting aside these lands for special air quality protection. And we need to fix these problems. The EPA cannot let Alaska power plants escape pollution controls; please require an adequate Alaska haze plan that would ensure clean air in Denali, and throughout the region for present and future generations. Thank you for considering my request. Sincerely,Mr. Leon Koenck 200 W 34th Ave # 539 Anchorage, AK 99503-3969 (907) 529-2558

Are we going to be saying: "Oh! You can't see Denali today because of the smog"? I, as an Alaskan want to keep the air here as clean and pristine as possible. No coal plants would be best, but if we must have them, then they must be required to have adequatehaze-limiting controls and be monitored. Thank you for considering my request. Sincerely, Miss R.

As such, its air quality should not be allowed to degrade. I urge you to strengthen Alaska's regional haze plan. Clean and clear air in Denali National Park and Preserve is important to me. Unfortunately, one industrial facility, Healy Units 1 and 2, is less than five miles from Denali, and is not being required to clean up enough to significantly decrease its impact on the park. Please improve your proposal and require greater pollution reductions from these park polluters. As a national park visitor and advocate for the parks, I value Denali's pristine air and breathtaking views. Unfortunately, EPA has approved an Alaska haze plan that will not adequately protect the places that I care deeply about. For Healy Unit 1, an older power plant, modern controls should be required to stem the haze pollution that currently threatens Denali's majestic lands. For Healy Unit 2, a newer facility, no pollution controls were proposed. This plan would allow the Healy Unit 2 to operate for five years or more, next door to Denali, without being evaluated for modern, haze-limiting controls. I ask that EPA require modern and effective pollution controls to mitigate haze before this facility restarts operations. Reduced views and compromised air quality are problems that Congress sought to fix by setting aside these lands for special air quality protection. And we need to fix these problems. The EPA cannot let Alaska power plants escape pollution controls; please require an adequate Alaska haze plan that would ensure clean air in Denali, and throughout the region for present and future generations. Thank you for considering my request.Sincerely, Mr. Richard Anderson 2321 Legacy Dr Anchorage, AK 99516-2643 (907) 522-0202

Mar 21, 2012 Administrator Dennis McLerran EPA Region 10, 1200 Sixth Avenue, Suite 900 Seattle, WA 98101 Dear Administrator McLerran, I urge you to strengthen Alaska's regional haze plan. Clean and clear air in Denali National Park and Preserve is important to me. Unfortunately, one industrial facility, Healy Units 1 and 2, is less than five miles from Denali, and is not being required to clean up enough to significantly decrease its impact on the park. Please improve your proposal and require greater pollution reductions from these park polluters. As a national park visitor and advocate for the parks, I value Denali's pristine air and breathtaking views. Unfortunately, EPA has approved an Alaska haze plan that will not adequately protect the places that I care deeply about.

Mar 21, 2012 Administrator Dennis McLerran EPA Region 10, 1200 Sixth Avenue, Suite 900 Seattle, WA 98101 Dear Administrator McLerran, As an Alaskan I urge you to strengthen Alaska's regional haze plan and to please stop exempting Alaskans from the protections offered via EPA's authority. The Alaskan people, our wildlife, and the environment all need the help of EPA's regulations, especially considering how polluted our state ALREADY is and that many of Alaska's decisions makers tend to favor development over the health concerns of the public and that of the environment. And our state now leads the rest of the country in Toxic Chemical releases. We need EPA's help to prevent more pollution from spilling into our environment not allowing more of it to continue. Coal, Coal Ash is one the worst pollutants, and our state already has a growing acidification problem. Our marine life and fisheries are also already suffering from pollution Please improve your proposal and require greater pollution reductions from the Healy Coal Power Plants. The EPA cannot let Alaska power plants escape pollution controls; please require an adequate Alaska haze plan that would ensure clean air in Denali, and throughout the region for present and future generations. Thank you for considering my request. Sincerely, Ms. Lorraine Murray PO Box 210192 Auke Bay, AK 99821-0192

Mar 22, 2012 Administrator Dennis McLerran EPA Region 10, 1200 Sixth Avenue, Suite 900 Seattle, WA 98101 Dear Administrator McLerran, I urge you to strengthen Alaska's regional haze plan. Clean and clear air in Denali National Park and Preserve is important to me. Unfortunately, one industrial facility, Healy Units 1 and 2, is less than five miles from Denali, and is not being required to clean up enough to significantly decrease its impact on the park. Please improve your proposal and require greater pollution reductions from these park polluters. As a national park visitor and advocate for the parks, I value Denali's pristine air and breathtaking views. Unfortunately, EPA has approved an Alaska haze plan that will not adequately protect the places that I care deeply about. For Healy Unit 1, an older power plant, modern controls should be required to stem the haze pollution that currently threatens Denali's majestic lands. For Healy Unit 2, a newer facility, no pollution controls were proposed. This plan would allow the Healy Unit 2 to operate for five years or more, next door to Denali, without being evaluated for modern, haze-limiting controls. I ask that EPA require modern and effective pollution controls to mitigate haze before this facility restarts operations. Reduced views and compromised air quality are problems that Congress sought to fix by setting aside these lands for special air quality protection. And we need to fix these problems. The EPA cannot let Alaska power plants escape pollution controls; please require an adequate Alaska haze plan that would ensure clean air in Denali, and throughout the region for present and future generations. Thank you for considering my request. Sincerely,Ms. Tiffany Derenzy PO Box 244595 Anchorage, AK 99524-4595

Mar 23, 2012 Dennis McLerran Dear McLerran, I care deeply about protecting public health, air quality at national parks and wilderness areas, and local economies supported by recreation and tourism. Golden Valley Electric Association's Healy Unit No. 1 plant ("Healy") is a coal-fired boiler that was constructed over forty years ago. Its emissions cause substantial visibility impairment in Denali National Park, and around the region. Denali is one of the nation's most magnificent national parks. Denali is a popular tourist destination that encompasses more than six million acres of open tundra gleaning with wildflowers, spruce trees, and valleys with glacier-fed rivers and lakes. Because Healy contributes to visibility impairment in Denali, it is subject to "Best Available Retrofit Technology" (BART) limits under EPA's Regional Haze Rule. . EPA should impose lower BART emissions limits for sulfur dioxide and nitrogen oxides at Healy that are consistent with modern pollution control technology to protect public health, the environment and Denali N ational Park. In the long term, Alaska's energy future is best founded on clean, efficient energy not coal. Sincerely, Renae Thompson 9731 Vanguard Dr Apt 16 Anchorage, AK 99507-5308

Mar 23, 2012 Dennis McLerran Dear McLerran, Coal fired power plants should be outlawed unless they can meet the standards of no emissions, like a plant burning hydrogen. We know they can't do that. Large corporations control our country. We are a long way from democracy. Until we regain control of our country, we are basically screwed. Big business will keep skimming off the profits produced by the workers and keep their wages low. If you think about that, that makes no sense, because if you don't pay workers they can't buy industries products, and the plants lay off or shut down. When you drive to Healy from the south at 40 below F. , you see a yellow brown smudge in the sky over most of Healy. Pollution from the power plant is not so visible in summer, although on windless days, the monitors would pick up particulates.

Mar 23, 2012 Dennis McLerran Dear McLerran, I care deeply about protecting public health, air quality at national parks and wilderness areas, and local economies supported by recreation and tourism. Golden Valley Electric Association's Healy Unit No. 1 plant ("Healy") is a coal-fired boiler that was constructed over forty years ago. Its emissions cause substantial visibility impairment in Denali National Park, and around the region. Denali is one of the nation's most magnificent national parks. Denali is a popular tourist destination that encompasses more than six million acres of open tundra gleaning with wildflowers, spruce trees, and valleys with glacier-fed rivers and lakes. Because Healy contributes to visibility impairment in Denali, it is subject to "Best Available Retrofit Technology" (BART) limits under EPA's Regional Haze Rule. .

Golden Valley Electric Association's Healy Unit No. 1 plant ("Healy") is a coal-fired boiler that was constructed over forty years ago. Its emissions cause substantial visibility impairment in Denali National Park, and around the region. Denali is one of the nation's most magnificent national parks. Denali is a popular tourist destination that encompasses more than six million acres of open tundra gleaning with wildflowers, spruce trees, and valleys with glacier-fed rivers and lakes. Because Healy contributes to visibility impairment in Denali, it is subject to "Best Available Retrofit Technology" (BART) limits under EPA's Regional Haze Rule. .

Mar 24, 2012 Dennis McLerran Dear McLerran, As an Alaskan resident it makes absolutely no sense to me to burn coal with anything but the best technology if coal has to be burned. I don't know how much the Golden Valley Electric Association's Healy Unit No. 1 plant ("Healy") coal burning plant will affect the views in national parks, and this should certainly be considered. However, adding unnatural levels of mercury to the food chain, from coal power plant emissions, is very much is a concern to me, especially since many Alaskans, at least partially, get their food from subistence resources that are predominantly pretty high up on the food chain when it comes to aquatic foods like salmon. Alaska is one of the last places on Earth where almost all of our fish is still safe for pregnant women and children to eat. This also contributes to the high market price Alaskan Wild Salmon and other Alaska seafood fetches in the world market. Lets keep it that way, especially considering that fish (especially salmon) is one of the best foods for pregnant woman and children to eat has the omega 3 fatty acids it contains are critical for proper brain development. Please subject the Healy coal plant to "Best Available Retrofit Technology" (BART) limits under EPA's Regional Haze Rule. The only thing better than this would be to not let coal be burned at all in a way that releases mercury into the atmosphere. Regardless the EPA should impose lower BART emissions limits for sulfur dioxide and nitrogen oxides at Healy that are consistent with modern pollution control technology to protect public health, the environment and Denali N ational Park. In the long term, Alaska's energy future is best founded on clean, efficient energy not coal. Sincerely, Lance Westing PO Box 622 Kotzebue, AK 99752-0622 (907) 442-4474

Its emissions cause substantial visibility impairment in Denali National Park, and around the region. Denali is one of the nation's most magnificent national parks. Denali is a popular tourist destination that encompasses more than six million acres of open tundra gleaning with wildflowers, spruce trees, and valleys with glacier-fed rivers and lakes. Because Healy contributes to visibility impairment in Denali, it is subject to "Best Available Retrofit Technology" (BART) limits under EPA's Regional Haze Rule. . EPA should impose lower BART emissions limits for sulfur dioxide and nitrogen oxides at Healy that are consistent with modern pollution control technology to protect public health, the environment and Denali N ational Park. In the long term, Alaska's energy future is best founded on clean, efficient energy not coal. Sincerely, Linda McNamara 525 McKee Farm Rd Fairbanks, AK 99712-3647 (907) 687-5117

Mar 23, 2012 Dennis McLerran Dear McLerran, Why not use alcohol all motors diesel, gas, 2 cycle or 4 are able to be converted. Emissions from alcohol is co2 and oxygen, much cleaner then fossil fuels. Heck even if we just added 15% denatured alcohol to current gas motors you would save around 75% of emissions. Also alcohol can be locally produced at a cost of no more then $1.30 a gallon. People seem to want to get rich at the cost of whatever; my kids life, your life my life. Anyway you look at it fossil fuels are uneconomical, environmentally hazardous and will only lead us to destruction of our species and possibly the rest of the life on our one and only planet EARTH.

Its emissions cause substantial visibility impairment in Denali National Park, and around the region. Denali is one of the nation's most magnificent national parks. Denali is a popular tourist destination that encompasses more than six million acres of open tundra gleaning with wildflowers, spruce trees, and valleys with glacier-fed rivers and lakes. Because Healy contributes to visibility impairment in Denali, it is subject to "Best Available Retrofit Technology" (BART) limits under EPA's Regional Haze Rule. . EPA should impose lower BART emissions limits for sulfur dioxide and nitrogen oxides at Healy that are consistent with modern pollution control technology to protect public health, the environment and Denali N ational Park. In the long term, Alaska's energy future is best founded on clean, efficient energy not coal. Sincerely, Steven Bergt 2600 Draper Dr Anchorage, AK 99517-1239 (907) 727-0767

Mar 25, 2012 Administrator Dennis McLerran EPA Region 10, 1200 Sixth Avenue, Suite 900 Seattle, WA 98101 Dear Administrator McLerran, I urge you to strengthen Alaska's regional haze plan. Clean and clear air in Denali National Park and Preserve is important to me. Unfortunately, one industrial facility, Healy Units 1 and 2, is less than five miles from Denali, and is not being required to clean up enough to significantly decrease its impact on the park. Please improve your proposal and require greater pollution reductions from these park polluters. As a national park visitor and advocate for the parks, I value Denali's pristine air and breathtaking views. Unfortunately, EPA has approved an Alaska haze plan that will not adequately protect the places that I care deeply about. For Healy Unit 1, an older power plant, modern controls should be required to stem the haze pollution that currently threatens Denali's majestic lands. For Healy Unit 2, a newer facility, no pollution controls were proposed. This plan would allow the Healy Unit 2 to operate for five years or more, next door to Denali, without being evaluated for modern, haze-limiting controls. I ask that EPA require modern and effective pollution controls to mitigate haze before this facility restarts operations. Reduced views and compromised air quality are problems that Congress sought to fix by setting aside these lands for special air quality protection. And we need to fix these problems. The EPA cannot let Alaska power plants escape pollution controls; please require an adequate Alaska haze plan that would ensure clean air in Denali, and throughout the region for present and future generations. Thank you for considering my request. Sincerely,Ms. Lilli Ohse PO Box 186 Seldovia, AK 99663-0186

Mar 25, 2012 Dennis McLerran Dear McLerran, I care deeply about protecting public health, air quality at national parks and wilderness areas, and local economies supported by recreation and tourism. Golden Valley Electric Association's Healy Unit No. 1 plant ("Healy") is a coal-fired boiler that was constructed over forty years ago. Its emissions cause substantial visibility impairment in Denali National Park, and around the region. Denali is one of the nation's most magnificent national parks. Denali is a popular tourist destination that encompasses more than six million acres of open tundra gleaning with wildflowers, spruce trees, and valleys with glacier-fed rivers and lakes. Because Healy contributes to visibility impairment in Denali, it is subject to "Best Available Retrofit Technology" (BART) limits under EPA's Regional Haze Rule. . EPA should impose lower BART emissions limits for sulfur dioxide and nitrogen oxides at Healy that are consistent with modern pollution control technology to protect public health, the environment and Denali N ational Park. In the long term, Alaska's energy future is best founded on clean, efficient energy not coal. I think we have to decide whether we want to live in a wasteland or to preserve the wilderness that remains. Time to wake up. Sincerely, Jill Burkert PO Box 33403 Juneau, AK 99803-3403
