JUDGE REJECTS ACTIVISTS' BID TO BLOCK EXPORT OF TOXIC NAVAL VESSELS

A federal judge has cleared the way for the Bush administration to export contaminated naval vessels for dismantling abroad, after dismissing environmentalists' lawsuit that charged the scheme violated U.S. environmental laws.

But environmentalists are still declaring a victory, saying the suit forced the Department of Transportation's Maritime Administration (MARAD) to conduct additional environmental analyses of its plans and apply to EPA for a rulemaking to determine whether the plan violated a long-standing ban on exports of polychlorinated biphenyls (PCBs).

EPA CHILDREN'S HEALTH ADVISERS TOLD PERCHLORATE LIMIT IS ADEQUATE

Researchers from the National Academy of Sciences (NAS) told an EPA advisory panel on children's health that an exposure limit recently adopted by the agency for the contaminant perchlorate is adequate to protect children and pregnant women. The exposure limit could be the basis of upcoming drinking water standards and cleanup requirements for the pollutant, and the EPA advisory panel is considering whether those measures are sufficient to protect children.

EPA RESEARCHERS REJECT INDUSTRY-BACKED METHOD FOR ASSESSING RISKS

EPA researchers say there is insufficient scientific research to support a new method industry favors for evaluating how people respond differently to toxic exposures.

EPA will announce the finding in a draft agency article that agency scientists plan to publish in a scientific journal, and is part of a broader agency effort to examine the scientific basis of so-called "safety factors" in EPA risk approaches.

PERCHLORATE DISPUTE SPARKS PLAN FOR BROADER FEDERAL TOXICS REVIEWS

Disagreement between the Department of Defense (DOD) and EPA on the risks posed by perchlorate has sparked interest from White House regulatory officials and other federal agencies in exploring ways to step up oversight of a key EPA database of chemical risk values that state and federal regulators use.

EPA FACES TOUGH CHOICE IN RE-REGISTRATION OF KEY WOOD PRESERVATIVE

EPA is facing a tough choice over whether to re-register a controversial wood preservative that the electric utility industry says is vital to transmitting power nationwide via wooden poles, but which states and environmentalists say harms human health and water quality through runoff to surface waters.

Revised DOD Environment Bill Offers Air Quality Concessions To States

In an apparent concession to states, the Pentagon has revised a legislative plan to grant the military exemptions from environmental laws by including a provision that would require a "written occurrence" by states for any project that might degrade air quality. State opposition to the Pentagon's plan is widely credited with having killed the effort last year in Congress, and environmentalists and other opponents of the draft legislation are raising concerns that it could be approved this year as part of an annual defense authorization bill.

LACK OF DATA TRANSPARENCY SOURS EPA ADVISERS ON NEW RISK MODEL

EPA science advisers appear split over the approach agency researchers have taken in building a cutting-edge quantitative risk model for pesticide exposure, with some questioning the agency's reliance on industry input and suggesting the tool's design is too ambitious, while others say only minor changes are necessary.
