This feature class represents the product of merge and dissolve operations in ArcGIS with the inputs being the individually submitted EIS boundary datasets. EIS boundaries were developed by each individual EIS in coordination with the Division of Decision Support, Planning and NEPA (WO 210). EIS boundary submissions occurred between Sept. 25th and Sept. 30th, 2013. No modifications to the source data have been made other than to add and calculate the "EIS Name" field.  The following EIS boundaries are included in the dataset: 9-Plan, Bighorn Basin, Billings/Pompey's Pillar NM, Buffalo, HiLine, Idaho and SW Montana, Lander, Lewistown, Miles City, NW Colorado, Nevada and NE California, North Dakota, Oregon, South Dakota, Upper Missouri River Breaks NM, and Utah.
