Monthly <br />monitoring at NPDES sites will be conducted during all months (winter monitoring exemption may <br />apply). <br />Triannual =Water quality samples (analyzed 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 (native), spoil springs, and stream sites, when sarpling for the <br />surface water parameter long list is required and flow is less than 5 gpm, only field parameters will be <br />measured. <br /> <br /> <br /> <br />C~ <br />TR-58 15-3a-4 Revised 04/07 <br />
