A document connected to the Horse Heaven wind and solar project in Washington state remains under wraps. The Energy Facility Site Evaluation Council declined to release a document detailing its reasons for recommending Washington Gov. Jay Inslee approve the contentious Horse Heaven wind and solar project. The council voted 5-2 on April 17 to send a report to Inslee that supports allowing up to 222 turbines and more than 5,000 acres of solar panels on rolling hills, mostly farmland, near the Tri-Cities.
