' Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceeI�dance for the same parameter at the same outfall.
z For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
3The total precipitation must be recorded using data from an on -site rain gauge. Unattended sites ma be eligible for a waiver of the rain gauge requirement.
4 See General Permit text, Table 3 or Table 4, identifying protected receiving water classifications wher the more protective TSS benchmark applies.
5 Stormwater discharges into receiving waters classified as saltwater are subject to the second listed b nchmark.
Note: Results must be reported in numerical format. For example, do not report Below Detection Limit, BDL, <PQL, Non -detect, ND, or other similar non -
numerical format. When results are below the applicable limits, they must be reported in the format, "<XX mg/If, where XX is the numerical value of the
detection limit, reporting limit, quantitation limit, etc. in mg/L.
in excess of the benchmark, you must implement Tier 1, Hier 2, or Tier 3 responses. See General P
