Developing a new paradigm for managing fine particulate air pollution.
Annette C. Rohr and Ronald E. Wyzga
The Environmental Protection Agency regulates emissions of particulate matter based on the mass of those emissions—not on the toxicity of the particular components. A growing body of evidence shows that different kinds of particulates affect health differently. Research by the Electric Power Research Institute suggests that in order to most effectively protect public health, the EPA’s next round of air quality standards should differentiate between relatively benign sulfate or nitrate compounds, and more harmful trace metals in particulate emissions.
An integrated approach could prove more effective for controlling emissions.
Sam Napolitano, et al.
Despite political challenges, the EPA and Congress have made strides toward a more coherent and integrated approach to regulating air emissions. The time is right to reach consensus on a multi-pollutant strategy.
How new market-based regulations fit with today’s programs.

What do the Clean Air Interstate Rule, the Clean Air Mercury Rule, and the Clean Air Visibility Rule require of the power sector? Authors from the Environmental Protection Agency review implementation progress.
THE ENVIRONMENTAL PROTECTION AGENCY HAS PROPOSED wide-ranging regulations that will increase the cost of electricity production, particularly at the nation's lowest-cost, coal-fired generators.
Despite a doubling of electricity generation since 1970, atmospheric concentrations of sulfur dioxide and nitrogen oxide have declined. Title IV acid rain provisions of the Clean Air Act Amendments of 1990 will result in even greater reductions over the next few years. EPA has nevertheless charted a course to reduce utility emissions of these pollutants even further.

LAST YEAR, IN JUSTIFYING THE PROPOSED NEW NATIONAL AMBIENT Air Quality Standards (NAAQS) for particulate matter and ozone, Environmental Protection Agency Administrator Carol Browner testified that: "During the 1990 debates on the Clean Air Act's acid rain program, industry initially projected the costs of an emission allowance¼ to be approximately $1,500¼ Today those allowances are selling for less than $100." %n1%n
Later in 1997, at the White House briefing announcing President Clinton's Global Climate Change Plan, Katie McGinty, chairwoman of the Council on Environmental Quality, sa
