Same as Note I plus continuous monthly field parameters and 4`h quarter full suite analysis. <br />3. Field parameters twice, June through October. Full suite 3'd quarter if sample is available. <br />4. Discharge and field parameters twice during June through October. <br />5. CDPS requirements including quarterly WET testing. <br />6. USGS Gage used for stream flow purposes only. <br />7. D to B Seam water transfer wells (D2B and D2B2) are monitored for annual flow, TSS, pH and water level <br />twice/year. <br />8. B-2 and B-3 are surface flow and field parameters only.
