' Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the 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.
3The 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 3, 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, <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/L". where XX is the numerical value of the
detection limit, reporting 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 text.
