'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 4requirement. 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 me/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 rer 1, rer 2, or Tier 3 responses. See General Permit text.

All permits require qualitative monitoring to be performed during a "measurable storm event." A "measurable storm event" is a storm event that results in an actual discharge from the permitted site outfall. The previous measurable storm event must have been at least 72 hours prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter interval is representative for local storm events during the sampling period, and the permittee obtains approval from the local DEMLR Regional Office.
