Two proposed wind farms to be located south of Glenrock, Wyoming, recently received approval from the state's Industrial Siting Council, a critical step forward for the 31-turbine projects, reports the Casper Star-Tribune.

According to the news source, while the projects were approved, the council added a number of new provisions, including the requirement that the developer limit the visual and audio impacts for nearby residents and put up a bond of $18.8 million.

Additionally, before developer Wasatch Wind can construct the turbines, it needs to demonstrate its financial ability to build, operate, maintain and ultimately raze them if necessary, the news provider said.

"We’re pleased with the outcome and we look forward to continuing to work with the citizens of Converse County, the local and state governments and agencies as we continue to develop this wind energy project," Michelle Stevens, a spokeswoman for the developer, said after the approval was granted.

According to The Associated Press, another condition added by the council is that the turbines themselves feature safety lights as a means of alerting aircraft in the area.
