During this quaver, four NPDES outfalls were active. Outfalls 001 and 002 discharged <br />routinely throughout the quarter. Outfall 011 commenced discharging in February and continued for the <br />remainder of the quarter. Outfall 017 discharged intermiventiy in response to snowmelt runoff during March. <br />Outfalls 003, 005, 006, 008, 009, 010, 012, 013, 014, 015, 016, 019, and 020 did not discharge during the <br />quaver. Outfall 018 is associated with a sediment pond which has not yet been constructed. No discharge is <br />repotted for this outfall. Values reported on the enclosed DMRs represent the maximum (or minimum as <br />applicable) monthly/daily values generated at each outfall during the quarter. <br />Also enclosed are monthly NOAA weather s~mma~es for the reporting period, seep volume data fot site 011, and <br />WET test repov forms as applicable.
