Supplement Analysis for Rail Tie Wind Project Environmental Impact Statement; Albany County, Wyoming
WAPA prepared a Supplement Analysis (SA) to evaluate the Rail Tie Wind Project Environmental Impact Statement (DOE/EIS-0543) in consideration of changes that could have bearing on the potential environmental impacts previously analyzed. Based on the analysis in the SA, WAPA determined that the refinements to the Federal action analyzed in the Final EIS do not constitute a substantial change nor present significant new circumstances or information relevant to environmental concerns warranting a supplemental EIS. No further NEPA documentation or agency decisions are required.
