Project Description

The Bureau of Land Management (BLM) has prepared this supplemental National Environmental Policy Act (NEPA) analysis to provide further analysis of the impacts to air quality and greenhouse gas (GHG) emissions that may result from future development of certain leases, in response to several lawsuits challenging the original analysis. This supplemental Environmental Assessment (EA) provides information to assist the BLM in choosing among the alternatives considered to make decisions regarding 285 authorized leases that were issued as a result of being sold at 14 competitive oil and gas lease sales in Colorado between May 2015 and December 2020, along with 21 pending leases from the BLM Colorado’s Northwest District’s September 2019 sale, which are located in Kremmling, Little Snake and White River Field Offices. These 21 pending leases are sold parcels; however, the BLM did not issue leases pending release of a Record of Decision (ROD) for the Greater Sage Grouse (GRSG) Resource Management Plan Amendment (RMPA).  The 285 authorized leases are comprised of 238,960 acres, while the 21 pending leases are comprised of 24,260 acres; total acreage across the 306 subject leases is approximately 263,220 acres.
