WASHINGTON (AP)  The Bush administration is proposing to let federal agencies decide for themselves whether highways, dams, mines and other construction projects might harm endangered animals and plants, according to a draft of planned rule changes obtained by The Associated Press.

The proposed regulations, which do not require the approval of Congress, would reduce the mandatory, independent reviews that government scientists have been performing for 35 years.

Interior Secretary Dirk Kempthorne said late Monday that the changes were needed to ensure that the Endangered Species Act not be used as a “back door” to regulate the heat-trapping gases linked to global warming.

The draft rules would bar federal agencies from assessing the emissions from projects that contribute to global warming and its effect on species and habitats.
