Enclosed is the monthly Storm water Discharge Monitoring Report for February. Orange County is
currently in Tier II monitoring for the facility due to high TSS. There were several measurable
storm/rain events during the month of February 2020. A sample was collected from each of the two
outfalls at the start of the rain event on February 3, 2020 approximately 30 minutes after it had begun.
Results indicate that the C&D and MSW outfalls threshold for fecal coliform were not exceeded. The
MSW outfall does 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.
The landfill is surrounded by heavily wooded areas and wildlife is frequently spotted on the landfill
property which explains fecal coliform presence in the discharge from C&D outfall.
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 kwitoskygorna eg coun nc.gov or call 919-918-
4916.

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.
