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.
'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 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, tfy-must be reported in the format, "<XX ma/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 Per►nR text.
