RE: Orange County MSW& C&D Landfills,NCG120065
Enclosed is the monthly Storm water Discharge Monitoring Report for December 2019. Orange County
is currently in Tier II monitoring for the facility due to high TSS. A sample was collected from each of
the two outfalls on December 2, 2019.
Results indicate that both the C&D outfall and the MSW outfall do not exceed any of the limits outlined
in the County's NPDES permit. The results of the analysis are entered on the enclosed Storm water
DMR reporting form as well as copies of both analyses.
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 at [e-mail] or 919-918-4916.
Sincerely,

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, 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.
J 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.
