Comments on the Draft SEIS are being reviewed for response in the Final SEIS. 

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

Substantive comments require a response in the form of a change to the analysis or text 
in the main body of the document or in an appendix.  

Substantive comments challenge the accuracy of information presented, challenge the adequacy, methodology or assumptions of the environmental or social analysis (with supporting rationale), present new information relevant to the analysis, or present reasonable alternatives (including mitigation) other than those presented in the Draft SEIS.

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.
