From the LA Times:
The National Park Service will allow as many as 540 snowmobiles a day to enter Yellowstone National Park -- a compromise that leaves neither environmentalists nor winter recreation advocates happy.
The proposed cap is less than the current limit of 720 but nearly twice the number that have been entering the park in the last four years, and would reverse a trend of cleaner air and less noise, environmentalists and former park employees said.
The decision, issued in Denver Tuesday, will require snowmobiles to use "best available technology" to control emissions and noise, and for access to be "commercially guided."
The new limits will take effect in the winter of 2008-09. T
