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