1 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.
A 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 mg/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.
