New air quality regulations, including the Cross-State Air Pollution Rule, have prompted substantial investments in emission control upgrades. But a series of additional standards—for mercury, toxins, cooling water and ash residue—are driving delays and shutdowns in the coal-fired power fleet. Investment decisions depend on a clear understanding of where EPA is headed, and how the new regulations will affect generators’ costs—and market prices.
The great debate over emissions allowance distribution.
Sam Napolitano et al.
Various approaches to distributing emissions allowances spark a heated debate over costs and fairness, but the allocation methodology doesn’t determine whether a regulatory scheme will reduce emissions. Auctioning allowances and distributing them for free both offer advantages and challenges for a successful cap-and-trade system.
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.
The 2008 elections portend federal regulation of greenhouse gases by 2010.
James I. Stewart and M. Sami Khawaja
The outcome of the 2008 elections will determine how the nation deals with greenhouse gas emissions. With the presumptive nominees for president for both parties supporting mandatory GHG regulation, a cap-and-trade system likely will become U.S. law. How soon and how tough depends on the choices voters will make in November.
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.
Eight states blame upwind sources. Agency to revisit emissions targets.
The U.S. Environmental Protection Agency's Sept. 24 rule for 22 eastern states to file plans to reduce nitrogen oxide emissions would ostensibly reduce transport of ground-level ozone, or smog, in so-called "nonattainment areas." But eight of these affected states have filed petitions arguing that NOx emissions blowing in from nearby jurisdictions must be controlled before they can comply.
So far, in preliminary statements, the EPA has indicated that at least some of these petitions have merit.
