The BLM is preparing the Final Supplemental EIS. 

Comments submitted during the 90-day public comment period that closed on June 9, 2016, are being 
analyzed and where appropriate, changes are being made to the analysis that will appear in the Final SEIS. 

Responses to substantive comments are reflected in changes to the analysis or text of the document.  

The Final SEIS will identify the Environmentally Preferable Alternative and the BLM Preferred Alternative, 
along with the land use plan amendments that would be needed to authorize the Preferred Alternative.

Mailing List
Join the mailing list to receive future updates and announcements about the supplemental EIS.


Mitigation measures or practices avoid, minimize, 
rectify, reduce over time or eliminate adverse effects to biological, physical or socioeconomic resources.

If an action alternative for segments 8 and 9 is selected in the Final Supplemental EIS, the BLM will identify what mitigation is required for the effects of the route alignments. 

Compensatory mitigation will be required for any 
impacts that would remain once avoidance, minimization and rectification measures are applied.
