Stormwater Monitoring CENTRAL FILES
DWR SECTION
Enclosed is the monthly Stormwater Discharge Monitoring Report for June 2016. Orange
County is currently in Tier II monitoring for the facility due to high TSS. The report indicates no
discharge for this month.
There were two qualifying rain events during the month. The events occurred during a time
period that the first flush discharge could not be captured in time to be collected or started too
late to be delivered to the testing laboratory within the hold time requirements for the testing
laboratory (maximum 6 hrs for E.Coli.).
Orange County continues to monitor the installed BMP's that help to control the amount of
onsite erosion and subsequent discharge of contaminated water; this includes the monitoring the
growth of our vegetative cover and minimizing the amount of disturbed land.
If you have any questions,please contact me at [e-mail] or 919-.968-2788.
Sincerely
Gordon Dively, PE

(mo/dd/yr) Inches3 Chemical Oxygen Demand Fecal Coliform Total Suspended Solids
Benchmarks===> - - 120 mg/L 1000 count per 100 mL 100 mg/L or 50 mg/L4
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.
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 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.
