Drain HVAC Closed Loop Hydronic System, Ironwood State Prison
Document Type
NOE - Notice of Exemption
Document Description
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.

Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
Categorical Exemption Class 1, CEQA Guidelines Section 15301 (Existing Facilities)
Reasons for Exemption
The project is categorically exempt from CEQA under the “Class 1” (14 CCR §15301) exemption per the CEQA Guidelines because the project involves negligible to no expansion of use. The project site is located within a previously disturbed area that is not considered environmentally or historically sensitive. This is one of a class of projects that the Secretary for Resources has found do not have a significant effect on the environment, and therefore is declared to be categorically exempt from the requirement for preparing an environmental document
