<br />STANDARD PROVISIONS AND REPORTING REQUIREMENTS, JANUARY 2012 - 20 - <br />FOR WASTE DISCHARGE REQUIREMENTS <br />FOR DISCHARGES REGULATED BY SUBTITLE D AND/OR TITLE 27 <br /> <br /> <br /> <br />25. The water quality protection standard shall consist of the constituents of <br />concern (COC), concentration limits, and the point of compliance. The water <br />quality protection standard shall apply during the active life of the waste <br />management unit, closure period, post-closure maintenance period, and any <br />compliance period under Title 27, section 20410 [Title 27, § 20390]. <br /> <br />26. The point of compliance at which the water quality protection standard applies <br />is a vertical surface located at the hydraulically downgradient limit of the waste <br />management unit that extends through the uppermost aquifer underlying the <br />unit [Title 27, § 20405). <br /> <br />27. The compliance period is the minimum period of time during which the <br />Discharger shall conduct a water quality monitoring program and is the number <br />of years equal to the active life of the waste management unit plus the closure <br />period [Title 27, § 20410(a)]. <br /> <br />28. The groundwater monitoring system shall include a sufficient number of <br />monitoring points, installed at appropriate locations, to yield groundwater <br />samples from the uppermost aquifer that represent the quality of groundwater <br />that has not been affected by a release from the waste management unit <br />[Title 27, § 20415(b)(1)(A)]. <br /> <br />29. The Detection Monitoring Program shall include a sufficient number of <br />monitoring points, installed at appropriate locations and depths to yield <br />groundwater samples from the uppermost aquifer that represent the quality of <br />groundwater passing the point of compliance to allow the detection of a release <br />from the waste management unit [Title 27, § 20415(b)(1)(B)1.]. <br /> <br />30. Additional monitoring points shall be added as necessary to provide the best <br />assurance of the earliest possible detection of a release from the waste <br />management unit [Title 27, § 20415(b)(1)(B)2.]. <br /> <br />31. The Detection Monitoring Program shall also include a sufficient number of <br />monitoring points installed at appropriate depths and locations to yield <br />groundwater samples from other aquifers or perched zones not already <br />monitored to provide the earliest possible detection of a release from the <br />waste management unit [Title 27, § 20415(b)(1)(B)3. and 4., and §20420(b)]. <br /> <br />32. A surface water monitoring system shall be established to monitor each surface <br />water body that could be affected by a release from the waste management unit <br />[Title 27, § 20415(c)]. <br /> <br />33. An unsaturated zone monitoring system shall be established for each waste <br />management unit [Title 27, § 20415(d)].
