The U.S. Bureau of Land Management has released a draft environmental analysis for the proposed 400-megawatt China Mountain wind farm  near the Idaho-Nevada border.  The Times-News reports that the agency has released the 1,200-page document and will take public comments through July 6.  RES Americas is a United Kingdom-based company behind the plan to build up to 170 wind turbines southwest of Rogerson, Idaho.  The company says some 200 megawatts would go to a Nevada utility.  The analysis cites possible ramifications of the wind farm on sage grouse habitat, and potential harm to visual aesthetics and cultural resources.  The analysis also notes concerns about being able to fight wildfires near the turbines.
