EPA STUDIES COULD SPARK NEW RISK LEVELS FOR ENDOCRINE DISRUPTORS

Three new EPA-funded animal studies examining the impact of endocrine-disrupting chemicals at extremely low doses could fine-tune agency risk levels for the controversial substances, environmentalist and agency sources say. The current risk levels were set by making extrapolations from high-dose effects.

LONG-AWAITED EPA GUIDANCE ON METAL RISKS ECHOES INDUSTRY CRITICISM

EPA's long-overdue draft framework for assessing the risks from metals emphasizes the need to incorporate more factors specific to these pollutants, echoing industry criticism of the agency's current risk review practices and possibly paving the way for relaxed toxic release reporting requirements.

In issuing the draft framework document Dec. 3, more than a year after it was promised, EPA is one step closer to completing a regulatory review process that began in 2002 and was aimed at updating its metals risk assessments.

EPA DECISION TO DELAY FORMALDEHYDE RISK REVIEW SPARKS UNCERTAINTY

EPA has agreed to a request from Senate environment panel Chairman James Inhofe (R-OK) to delay a formaldehyde risk review, creating uncertainty for plywood makers, the natural gas turbine industry and states about Clean Air Act exemptions for the pollutant the industries have been granted or are seeking.

The industry groups sought the exemptions by arguing that formaldehyde emissions from their operations posed minimal risks. But the delay in EPA's risk review may alter the data that the agency relied on when initially proposing to grant the regulatory waivers, sources say.

EPA, States Moving To Fill Policy Void For Asbestos In Soil Cleanups

EPA and state regulatory agencies are responding to a current void in asbestos cleanup standards and new risk analyses to develop guidance and regulations for addressing asbestos in soil, regulators say.

As part of those efforts, EPA is finalizing new guidance on asbestos risk assessment, field sampling and analytical methods, and at least two states are developing regulations on how to handle the discovery of asbestos-containing materials during the redevelopment of former industrial property.

EPA PLAN FOR SETTING SELENIUM PERMIT LIMITS COULD BE MODEL FOR MERCURY

EPA is proposing a controversial mathematical formula to calculate permit limits for a new fish tissue-based water quality criterion for selenium, a plan that may foreshadow how the agency will develop similar permit limits for its mercury fish tissue standard.

EPA officials say the plan for developing selenium permit limits could draw fire from industry officials opposed to agency efforts to develop a similar plan for mercury.

EPA FACES PRESSURE TO INCLUDE NEUROLOGIC TESTS IN PESTICIDE DECISIONS

EPA is facing 11th-hour pressure from children's health groups to routinely require tests evaluating the impact of pesticides on children's nervous systems when registering the chemicals.

The request comes as agency pesticide officials are finalizing negotiations with the White House Office of Management & Budget (OMB) over proposed revisions to regulatory requirements for data that support decisions on pesticide registration.
