Petisie is gerig aan: Yavapai County Board of Supervisors, Town of Chino Valley, Arizona and concerned citizens

A 3.6-megawatt, 5,000 acre utility scale solar farm is planned to be built on ranchland in Yavapai County, Arizona adjacent to an existing rural residential area. The project will also include a Lithium-Ion Battery Energy Storage System (BESS) and a 500-kilovolt transmission line.
Lithium-Ion fires produce hydrogen fluoride HF, phosphorus pentafluoride (PF5) and phosphoryl fluoride (POF3). Compounds containing fluorine can also be present and can linger in soil for an extended period.

The dangers associated with Battery Energy Storage Systems are well documented. I am strongly opposed to utility scale solar systems being built outside of established industrial zones and within 500 ft of residences. Join us in saying NO TO BESS!
