' Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
2 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, 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.
