Bonneville Power Administration (BPA) proposes to replace the heating, ventilation, and air conditioning (HVAC) system at BPA’s John Day Substation control house near Rufus, Sherman County, Oregon. The existing HVAC system has exceeded its useful service life and would be replaced by a modern and more energy-efficient HVAC system with built-in redundancy.
