The ban on road building and most logging in a third of the country’s national forests will be revised by the Bush administration to allow decisions to be made locally on a forest-by-forest basis. Until a new rule is devised, however, the access ban put in place by former-president Bill Clinton will remain in place until each forest is analyzed. Exactly how the new rule would be crafted was still unclear, but officials said the Agriculture Department, which oversees the Forest Service, hoped to have new regulations ready in a matter of months.

The forest rules, announced Jan. 5, were supposed to take effect in March. The Bush administration delayed implementation until May 12 while it conducted a review. Official announcement of the decision to revise the plan was expected Friday at a news conference by Agriculture Secretary Ann Veneman, whose agency oversees the Forest Service.
