WATER QUALITY PROTECTION STANDARDS <br /> The Water Quality Protection Standard (Standard) shall consist of the following elements : <br /> 1 . Constituents of Concern 4 . Points of Compliance <br /> 2 . Concentration Limits 5 . Compliance Period <br /> 3 . Monitoring Points <br /> Each of these is described as follows : <br /> 1 . Constituents of Concern <br /> The ` COC list ' (list of Constituents of Concern required under 27 CCR 20395 ) shall include all <br /> constituents listed in Attachment D . The Dischargers shall monitor all COCs every five years , or <br /> more frequently if required under a corrective action monitoring program . <br /> a. Monitoring Parameters <br /> Monitoring parameters are constituents of concern that are the waste constituents , <br /> reaction products , hazardous constituents , and physical parameters that provide a reliable <br /> indication of a release from a surface impoundment. The monitoring parameters for the <br /> specified monitored medium are those listed in Table I through IV . <br /> 2 . Concentration Limits <br /> The Discharger shall determine the Concentration Limit for any given Constituent of Concern or <br /> Monitoring Parameter in a given monitored medium (i . e . , groundwater and surface water) at the <br />
