In response to the benchmark value exceedances,the County implemented a Tier II response. There was no discharge from Outfall 3 in July 2016. Per the Tier II response requirements,samples will be collected monthly for COD from Outfall 3 until three consecutive sampling events show the parameter is below the benchmark value.The County will maintain a record of the Tier II response and monitoring results at the landfill.

'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. 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,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.
