NEW YORK HIGH COURT UPHOLDS STATE'S EMERGENCY ACID RAIN RULES

The New York Supreme Court upheld emergency acid rain rules that require power plants in the state to install year-round nitrogen oxide (NOx) pollution controls, and reduce NOx and sulfur dioxide (SO2) emissions far beyond federal requirements. The court last month rejected an industry appeal of the emergency rules.

With the temporary rules finally taking effect, New York will become the first state to require NOx emission reductions of 70 percent and SO2 reductions of 50 percent, creating the most far-reaching acid rain program in the nation.

NEW CLEAN COAL PLANT MAY EXPAND METHOD'S USE TO MORE COAL TYPES

A Southern power company's planned new advanced coal gasification power plant -- partially funded with over $200 million from the Department of Energy (DOE) -- will rely on technology that could make it less expensive to use what is known as low-ranked coal in energy-efficient gasification facilities, according to sources tracking the issue.

Low-rank or low-heat value coals generate less energy per quantity of coal burned, and their emissions have typically been harder to reduce than emissions from burning other coal types.

MERCURY EXPOSURE STUDY MAY GAUGE HEALTH OF POWER PLANT WORKERS

A pending study on human exposure to mercury could include unprecedented data on power plant employees who may face elevated risks in the workplace, sources involved with the research say. The upcoming study is part of activists' efforts to include groups from outside the environmental community, including labor unions, in a push for EPA to strengthen its rule requiring power plants to reduce mercury emissions.

INDUSTRY DOCUMENT REVEALS STRATEGY TO OPPOSE CLEAN AIR INITIATIVES

An industry group that represents coal producers and suppliers has been carrying out an ambitious strategy for defeating or scaling back a host of ongoing congressional and state initiatives to limit greenhouse gases, mercury and other air pollutants, according to a recent internal letter obtained by Inside Washington Publishers.

EPA ISSUES GUIDANCE FOR CLEAN AIR CREDIT THROUGH VOLUNTARY EFFORTS

EPA has issued a guidance that allows states to win credit for reducing emissions in their clean air plans through use of innovative voluntary and emerging measures. Agency sources say the guidance could help promote and validate these efforts so they could eventually become standard components of state air pollution strategies.

EPA COST-EFFECTIVENESS STUDY ON PM CONTROLS FINDS HUGE BENEFITS

A major new EPA study of the benefits of particulate matter (PM) controls suggests that costly air quality regulations -- like the clean air interstate rule and diesel rules -- have almost three times as many benefits as necessary to be considered cost-effective.

The finding could give agency officials leeway to argue for strict regulatory requirements because they can justify high costs the regulations may impose on regulated entities.

GROUPS CITE 'UNREASONABLE DELAY' RULING TO SPEED EPA AIR TOXICS RULES

Environmentalists are citing a recent federal appeals court's unusually detailed ruling defining when an agency's timetable for action is unreasonable to urge the court to take a particularly strong step to make EPA promptly set new air toxics standards for cement kilns required by a 2000 court order.

EPA CONSIDERS FLEXIBLE PERMIT STRATEGY FOR AREA SOURCE TOXIC RULES

EPA is considering whether to relax federal permit requirements in a host of pending new air toxics standards for industrial categories with relatively low emission levels, classified under the air act's "area source" program, according to state officials engaged in discussions with the agency. The officials are working with EPA on approaches for developing 50 long-delayed area source toxics standards, amid concerns about excessive regulatory burdens on state agencies.

WESTERN AIR CHIEFS CONSIDER NEW MODELING RULES, CHANGES TO AIR ACT

Air officials from Western states may ask EPA to issue a series of rulemakings that would overhaul a controversial industrial permit process with a major impact on the region. The pending recommendations come in the heat of a controversy over how much industrial expansion should be allowed in fast-growing parts of the country near park and wilderness areas.

In addition to regulatory proposals, the air officials could also recommend more far-reaching changes that would require amendments to the Clean Air Act.
