Bonneville Power Administration (BPA) proposes to replace the rooftop heating, ventilation, and air conditioning (HVAC) system at BPA's Ostrander Substation control house in Clackamas 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.
