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. Note: Results must be reported in numerical format. 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, 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.

(See information below.) Yes ❑ No Please verify whether Qualitative Monitoring must be performed during a "representative storm event" or "measureable storm event" (requirements vary, depending on the permit). Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be performed during a "representative storm event" or during a "measureable storm event." However, some permits do not have this requirement. Please refer to these definitions, if applicable. A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than 0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no precipitation. 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 DWQ Regional Office.
