EPA Data Not Reliable, Business Lobby Says

The U.S. Chamber of Commerce has red-penciled what it views as errors in 16 databases that the Environmental Protection Agency uses to make regulatory decisions about chemical cleanups and other policies that affect states and business. The chamber is not accusing the agency of manipulating the data, but of negligence in assuring users that the numbers are reliable.

Because the numbers are key to creating mathematical models that predict the behavior of various chemicals in the environment -- for example how they might move in soil or how concentrated they might be -- the group has asked for corrections. The issue is important to the business community, the chamber argues, because determinations based on these databases might result in rules that are too protective, and hence more costly.

In filing a petition at the EPA a year ago, the chamber noted, for example, that a numerical value for a benzene compound differed by a factor of more than 10 billion from one EPA database to another. Such discrepancies, it said, have led to "serious mistakes and erroneous conclusions" affecting estimates of how chemical exposure affects human health, what prevention measures are necessary and how much solving the problem should cost. It also charged that EPA's peer reviews did not uncover the mistakes.

The powerful business lobby told EPA "erroneous or inconsistent parameters in these databases" can have "huge financial implications" for its members who have to pay for Superfund cleanups or comply with other regulations that may be overly protective.

The chamber invoked the 2002 Information Quality Act in seeking the changes. The law requires federal agencies to respond to complaints directed at the reliability and accuracy of information they disseminate to the public and use in public policymaking decisions.

"We aren't trying to force withdrawal, but to get the numbers right," said William Kovacs , chamber vice president of environment, technology and regulatory affairs. "We want them to 'fess up and get it right. Our contention is if they disseminate this data, they are responsible for its correctness."

The EPA, by and large, did not buy the arguments.

In a Jan. 12 response, the agency said in general, the databases and models conformed to EPA information quality guidelines. It said it added two sentences to one database to "clarify appropriate use of the data" and it removed for review another used to assess how chemicals move in the soil.

The chamber came back to EPA in April and asked it to reconsider, an appeal allowed under the law. "EPA's response . . . is alarming in that it rejects a requested review of erroneous data, largely disclaims or ignores the fact that problems exist, and blatantly fails to address the public need for quality information . . . thereby placing the onus for examining and assuring data quality on the users," the document said.

The trade group asked the agency to convene an interagency task force, including officials from the National Institute of Standards and Technology , to formulate a way to assure the information is consistent and reliable.

Reginald Cheatham , director of EPA's quality staff, said the agency will convene an executive panel of EPA senior managers to review the appeal and will have an answer to the chamber by July. "We are working on it here and in the regions. We have at least 16 [people] working on this," he said. He said he could not address the debate on the merits or draw any conclusions while the agency is deliberating.

Cheatham said the agency took a "proactive step" in adding a disclaimer on one of the databases and removing another. "We have to recognize that EPA is continuing its effort to provide high-quality data and information in all its decisions," he said.
