Chlorine industry says EPA rules ignore good science

Article Abstract:

The Chlorine Chemistry Council alleges that the US Environmental Protection Agency (EPA) did not use the best available scientific information when it established targets for the maximum amount of chloroform permitted in drinking water. EPA scientists undertook an extensive review of chloroform over a five year period, and the EPA concluded as a result of this work that a nonlinear approach is better for extrapolating low-dose cancer risk than a low-dose linear approach. However, the EPA reverted to the linear approach when it ruled in Dec 1998 that the target for chloroform in drinking water should be zero.

Regulators face questioning on particulate rules

Article Abstract:

The American Lung Association has filed a lawsuit against the EPA after the agency failed to upgrade airborne particulate matter (PM) standards, which should be done every five years. The revision of standards required an evaluation of the risk assessment plan by the agency's Clean Air Scientific Advisory Committee (CASAC). CASAC has rejected an earlier standard proposed by EPA due to insufficient supporting data and lack of a detailed scientific methodology for arriving at the proposed regulations for particulates.

US air pollution rules stir up a stink about research

Article Abstract:

A congressional challenge is expected to President Bill Clinton's approval of new US rules on air pollution, which are only slightly looser than the Environmental Protection Agency proposals. Scientists, however, believe that the the issue of new rules could be a way of stimulating greater investment which they feel has been lacking. A further $40 million has already been earmarked for ozone and particulates research.
