RE: Orange County MSW& C&D Landfills,NCG120065
Enclosed is the monthly Storm water Discharge Monitoring Report for May 2020. Orange County is
currently in Tier II monitoring for the facility due to high TSS. There were some minor storm/rain events
during the month of May 2020. A sample was collected from each of the two outfalls at the start of the rain
event on May 28,2020 approximately 30 minutes after it had begun.
Results indicate that both C&D outfall and the MSW exceed the limits of e coli outlined in the County's
NPDES Permit. Analyses are entered on the enclosed Storm water DMR reporting form as well as copies of
both analyses.
The sampling results over the last twelve months for the outfalls have shown high levels of e coli following
periods of low rainfall. The landfill is surrounded by heavily wooded areas and wildlife is frequently spotted
on the landfill property which is the only way to explain fecal coliform presence in the discharge from C&D
outfall. The C&D landfill only accepts construction and demolition debris which should not be a source that
would lead to the presence of fecal coliform. The presence of fecal coliform in the MSW outfall is most
likely from the wildlife as well as the MSW landfill was officially closed in July 2013 and officially capped
with a subtitle D final landfill cap. The rainfall that follows a dry period appears to wash the accumulated
animal droppings to the outfalls.
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 kwitosky(a,ornagecountync.gov 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.

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
] The reported value is between the laboratory method detection limit(MDL)and the laboratory method
reporting limit(MRL),adjusted for actual sample preparation data and moisture content,where applicable.
U The analyte was analyzed for but not detected to the level shown,adjusted for actual sample preparation
data and moisture content,where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument.This value is considered an estimate.
MRL Method Reporting Limit.The MRL is roughly equivalent to the practical quantitation limit(PQL)and is
based on the low point of the calibration curve,when applicable,sample preparation factor,dilution
factor,and, in the case of soil samples, moisture content.
PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL.
N The analysis indicates the presence of an analyte for which there is presumptive evidence(85%or greater
confidence)to make a"tentative identification".
P Greater than 25%concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
[CALC] Calculated analyte-MDL/MRL reported to the highest reporting limit of the component analyses.
Q-01 Analysis performed outside of method -specified holding time.
