Colorado conservation groups are rallying the troops in Golden today for one of only three forums nationwide that the U.S. Bureau of Land Management (BLM) is conducting on the controversial natural gas drilling process called hydraulic fracturing, or “fracking.” BLM director Bob Abbey is weighing whether to require public disclosure of chemicals used in fracking operations on federal lands. Today’s BLM meeting will be held from 4 p.m. to 9 p.m. at the Denver Marriott West in Golden.
