As outlined in the Work Plan Specifications prepared by CDCR, the project will involve flushing and filtering the existing HVAC closed loop chilled water supply at Ironwood State Prison (ISP) and discharging the water into the existing storm water drainage system which flows to the onsite storm water retention basin. In order to comply with the State Water Resources Control Board Water Quality Order No. 2003-003-DWQ: General Waste Discharge Requirements (WDRs) for Discharges to Land With a Low Threat to Water Quality (General WDRs), the water will be tested for pH, Chemical Oxygen Demand, Total Copper and Iron, Total Dissolved Solids, Silica, Molybdenum, Azole, and microbiological constituents. The water quality results will meet the required water quality objectives before it is discharged into the retention basin. This project is a one-time discharge of water within hydronic loop system, due to debris issues. Approximately 1.7 million gallons will be discharged to onsite storm drains and eventually into the onsite retention basin. The project is needed to prolong the continued use of the HVAC system at ISP.
