'For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a check mark 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 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, <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 mR/L where XX 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 text.
