'Monthly sampling (instead of semiannual) must begin with the second consecutive benchmark exceedance for the same parameter at tnesame outran.
'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 text, Table 1, identifying protected receiving water classifications where the more protective TSS benchmark applies.
'Stormwater discharges into receiving waters classified as saltwater are subject to the second listed benchmark.
/mw*, 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 limbs, they must be reported in the format "<Xx mg/L!' where )0( is the numerical value of the
detection limit, reporting limit, quantitation limit, etc. in mg/L
Note: If you report a sample value in excess of the benchmark you must implement Tier 1 Tier 2 or Tier 3 responses. See General Permit.
