Monthly monitoring at NPDES sites <br />will be conducted during all months. <br />Triannual =Water quality samples lanalyzed according to the surface water parameter long <br />list) are collected during the key hydrologic events of spring snowmelt, late spring-early summer <br />baseflow, and fall baseflow. <br />Continuous =Continuous flow monitoring except during the winter months when the stilling <br />wells and flumes are frozen. <br />NOTE: For all springs (nativel, spoil springs, and stream sites, when sampling for the <br />surface water parameter long list is required and flow is less than 5 gpm, only field parameters <br />will be measured. <br />153a-3 Revised 01102 <br />
