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 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 ma/L", where XX is the numerical value of the detection limit, reporting limit, etc. in mg/L. Conversely, where fecal coliform results exceed the dilution upper limit, report the result as ">XX".
