1 Monthly sampling (instead of semi-annual) must begin with the second consecutive
same parameter at the same outfall.
' For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
' The total precipitation must be recorded using data from an on -site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
' See General Permit, Table 1 identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
Note: Results must be reported in numerical format. For example, do not report Below Detection Limit, BDL, <POL, Nun-detea, ND, or other similar non -numerical format. When results are below the applicable limits, thw
must be reported in the format. "<XIt mg/L". where XX is the numerical value of the detection limit, reporting limit, etc. in mg/L Conversely, where fecal coliform results exceed the dilution upper limit, report the result as
">%X".
