An overview of the regional clean air partnership of 1999

During the summer months, haze is often caused by smoke from fires caused by wildfires, prescribed burning, and agricultural burning. In addition, particles such as nitrates and sulfates contribute to acid rain formation, which makes lakes, rivers, and streams unsuitable for many fish, and erodes buildings, monuments, and paint on cars.

Acid rainwhich includes wet and dry deposition of acidic compounds from the atmosphere, results from emissions of sulfur dioxide and nitrogen oxides. Haze also has an economic consequence.

EPA's first steps to reduce harmful greenhouse gas pollution focused on motor vehicles. The law uses multiple tools including the phase-out of certain chemicals, bans on nonessential products containing or made with such chemicals, and prohibition of the release of ozone-depleting refrigerants during the service, maintenance, and disposal of air conditioners and other refrigeration equipment.

Tribal Governments For Common Pollutants: The Regional Haze Rule called for states to establish goals for improving visibility in national parks and wilderness areas and to develop long-term strategies for reducing emissions of air pollutants that cause visibility impairment in their own states and for preventing degradation in other states.

Public health is protected as economic growth proceeds. Toxic emissions from onroad and nonroad vehicles and engines also are dropping due to requirements for cleaner fuels and engines.

Tribal Resources

Top of Page The scenic vistas in our national parks are clearer due to reductions in pollution-caused haze. Helping developing countries comply through mechanisms like the Montreal Protocol's Multilateral Fund MLF will help assure success in restoring the ozone layer.

Impacts of Haze Haze not only impacts visibility, but some haze-causing pollutants have been linked to serious health problems and environmental damage as well.

Progress Cleaning the Air and Improving People's Health

Between the to and to observation periods, wet deposition of sulfate which causes acidification decreased by more than 55 percent on average across the eastern United States. Preconstruction permits are required for major new and modified stationary sources.

The law required EPA to issue the implementing rules, track the trading of emissions allowances, and monitor compliance.

SawtoothWilderness Area Haze impacts how far we can see and how clear the view appears. Elsewhere, EPA is the permitting authority. Clean Air Act Overview. EPA provides guidance and technical assistance to assist state planning, issues national emissions standards for new stationary sources, and reviews state plans to ensure that they comply with the Act.

Top of Page Interstate air pollution has been reduced. For the latest information about reducing air toxics, see the webpage, Reducing Emissions of Hazardous Air Pollutants. A peer-reviewed EPA Report to Congress reviewed the benefits of the Act from toand concluded that in alone, pollution reductions under the Act preventedearly deaths, This has improved visibility over broad regions, including many of our national parks.

Federal Actions to Address Regional Haze To address the aesthetic, public health, and economic impacts of haze, Congress amended the Clean Air Act in to establish national goals for visibility. Exposure to very small particles in the air can contribute to increased respiratory illness, decreased lung function, and even premature death.

Better air quality through cleaner fuels and vehicles – the Partnership for Clean Fuels and Vehicles (PCFV) Overview • Why? The challenge of air pollution • What is the Partnership for Clean Fuels and Vehicles?

• What have been its successes? • How has the Partnership operated? • What have we learned from this partnership? INTRODUCTION TO THE REGIONAL HAZE RULE REQUIREMENTS Purpose of the Plan adopted the Regional Haze Rule in The Rule lays out specific requirements to ensure improvements in the anthropogenic components of visibility at of the largest national parks and The Western Regional Air Partnership (WRAP) serves this function in the.

Section Two: Overview We disagree with the statement on page 8 claiming that North Dakota has four mandatory federal Class I areas as defined under the Clean Air Act. The Clean Air Status and Trends Network (CASTNET) is a national air monitoring network that provides data for determining relationships between emissions, air quality, deposition, and ecological effects.

The Clean Air Act calls for state, local, federal and tribal governments to implement the Act in partnership to reduce pollution. Roles vary depending on the nature of the air pollution problem. Jul 01,  · Federal Register/Vol.
