LEWISTON, Idaho (AP) — Environmental groups have written a letter to the U.S. Forest Service requesting more time for public comment on plans for Idaho’s Nez Perce-Clearwater National Forest.

The coalition of a dozen environmental advocacy organizations sent a letter to the agency Monday asking for a 90-day extension due to interruptions caused by the holiday season, The Lewiston Tribune reports.

The letter to Nez Perce-Clearwater Supervisor Cheryl Probert said the Dec. 20 release of the draft forest plan revision and environmental impact statement effectively removes about two weeks from the 90-day comment period.

Even those with time to examine the document are not likely to be able to reach forest service employees during holiday break periods, the groups said.

The Nez Perce-Clearwater National Forest did not immediately return a call from The Associated Press Tuesday.

The two draft documents released by the forest service broadly describe management of Nez Perce-Clearwater for the next 15 to 20 years.

The documents are revisions of the individual Nez Perce and Clearwater forest plans that were last updated in 1987.
