'Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmarkexceedance for the same parameter at the same outfall.
2For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a check mark 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 min gauge
'requirement. See General Permit text, Table 1, 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 me/L". where )N is the numerical value of the
detection limit, reporting limit, quantitation limit, etc. in mg/L.
Note: if you report a sample value In excess of the benchmark you must implement Tlerl, 7,er2, or tier 3 responses. See General Permit text

Dear Parker Aivis,
Endosed is a copy of your laboratory report for test samples received by our laboratory on
Wednesday, November 4, 2020.
Unless otherwise noted in an attached project narrative, ail samples were received in
acceptable condition and processed in accordance with the referenced methods/procedures.
Results for these procedures apply only to the samples as submitted.
The analytical results contained in this report are in compliance with NELAC standards, except
as noted in the project narrative if applicable. This report shall not be reproduced except in
full, without the written approval of the Laboratory.
This report contains only those analyses performed by Environmental Conservation
Laboratories. Unless otherwise noted, all analyses were performed at ENCO Cary. Data from
outside organizations will be reported under separate cover.

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected In the associated method blank.
D The sample was analyzed at dilution.
7 The reported value Is between the laboratory method detection limit (MDQ 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 Umit. 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 Umlt. 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.
ICALC] Calculated analyze - MDLJMRL reported to the highest reporting limit of the component analyses.
