The Chula Vista Police Department Headquarters (PDHQ) was constructed in 2003, and the Heating, Ventilation and Air Conditioning (HVAC) system has been operating continuously (7/24) there. The HVAC system provides thermal comfort acceptable indoor air quality for the entire facility. Over the last 12 years it is estimated that the plant, air-handlers and associated control systems are nearing over 100,000 hours of operation. Many components of the HVAC system are reaching the end of their life cycle and are in need of comprehensive maintenance and /or replacement.

Thus, no environmental review is necessary.
