TAKING CHARGE Bush delays regulations issued in the last days of Clinton Administration

W

BUSH

ITHIN HOURS OF BECOM-

ing the nation's chiefexecutive, President George W. Bush put the kibosh on the spate of regulations issued at the very end of the Clinton term. The Occupational Safety & Health Administration's revised regulation on how employers track and record workplace injuries and illnesses is one of the rules affected. That rule would update OSHA record-keeping requirements that date back to 1971. Other affected regulations include the Environmental Protection Agency's recently issued

standards lowering the permissible amount of sulfur in diesel fuel and arsenic in drinking water. Bush took the action so his Administration officials can review—and possibly change or withdraw—the crop of rules completed just before Bill Clinton left office. According to an EPA spokesman, such orders are common during presidential transitions. Most regulations affected likely will end up issued after Bush Administration officials get a chance to look them over and make any alterations deemed necessary, he adds.

The directive, issued byWhite House Chief of StaffAndrew H. Card Jr., delays for 60 days the effective date ofjust-issued regulations—those published in the FederalRegister— to allow time for the review Changing these rules would likely be cumbersome, since agencies would have to formally propose alterations, then solicit and review public comments before making any changes final. In addition to rules already issued, the order applies to final or proposed regulations signed by a Clinton Administration official but not yet published in the Federal Register. These rules and proposals are to be formally issued only after they have been reviewed—possibly changed, which requires no public notice —and approved by a Bush appointee.—CHERYL HOGUE
