RE: Discharge Monitoring Report — December 2019
Halifax County Landfill
Certificate of Coverage #NC6120040
Dear Sir/Madam:
RECE11/FD
JAN 10 2020
CENTP,AL FILES
D" SECTION
On behalf of Halifax County, Smith Gardner, Inc. (S+GI is pleased to submit the attached Tier
3 Discharge Monitoring Report (DMR) and associated analytical report for stormwater
monitoring at the Halifax County Landfill. The facility is permitted to discharge stormwater
related to landfilling activities under Certificate of Coverage (CDC) Number NCG120040,
General Permit Number NCG120000. The facility is required to monitor discharge at
Stormwater Discharge Outfall (SDO) Basin #1.
Basin # 1 entered Tier III status for chemical oxygen demand 1COD) in November 2019. There
were no exceedances for this sampling period (December 20191. The initial increase in COD
results occurred during landfill closure activities in June 2019. Since landfill closure was
completed in October 2019, COD concentrations have reduced and we anticipate that flow to
this basin will decrease over time. Based on the landfill now being closed, Halifax County and
S+G plan to submit a permit modification application to reduce or remove monitoring for this
facility. Additionally, a C&O landfill will be starting operation soon and the permit
modification application will also address this change.
We are providing two (2) copies of the December DMR report for this submittal. If you have
any questions, or require further information, please contact us via phone at [919) 828-0577
or by email.
Sincerely,
SMITH GARDNER, INC.

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.
'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 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 mR/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.
