Collected' amount,3Total Suspended Solids
(mo/dd/yr) Inches
Benchmarks===> - - 100 mg/L or 50 mg/L4
001 07/07/2016 0.5 8.3

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.
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 mg/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 Tier 1, Tier 2,or Tier 3 responses. See General Permit text.
