1 Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
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.
4 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 me/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".
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.

FOR PART A AND PART B MONITORING RESULTS:
• A BENCHMARK EXCEEDANCE TRIGGERS TIER 1 REQUIREMENTS. SEE PERMIT PART II SECTION B.
• 2 EXCEEDANCES IN A ROW FOR THE SAME PARAMETER AT THE SAME OUTFALL TRIGGER TIER 2 REQUIREMENTS. SEE PERMIT PART II SECTION B.
• TIER 3: HAS YOUR FACILITY HAD 4 OR MORE BENCHMARK EXCEEDENCES FOR THE SAME PARAMETER AT ANY ONE OUTFALL? YES ❑ NO ❑
IF YES, HAVE YOU CONTACTED THE DWQ REGIONAL OFFICE? YES ❑ NO ❑
