RE: Orange County MSW& C&D Landfills,NCG120065
Enclosed is the monthly Storm water Discharge Monitoring Report for June 2020. Orange County is
currently in Tier II monitoring for the facility due to high TSS. There was only one significant storm/rain
event during the month of June 2020; however,unfortunately,the events occurred at a time when a first
flush sample could not be collected.
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 monitoring of the growth of our
vegetative cover and minimizing the amount of disturbed land.
If you have any questions,please contact me via email [e-mail] or by phone at
919-918-4916.

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.
