RE: Discharge MonitoringReport—March 2020
OWE
Halifax County Landfill
Certificate of Coverage#NCG120040
Dear Sir/Madam:
On behalf of Halifax County, Smith Gardner, Inc. (S+G) 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 (COC) 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 (COD) in November 2019. Basin
#1 samples were below benchmark thresholds for COD, fecal coliform, and TSS this
sampling period. 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&D landfill will be starting operation soon and the permit modification
application will also address this change.
We are providing two (2) copies of the March DMR report for this submittal. If you have any
questions, or require further information, please contact us via phone at [phone] 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.
`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.
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 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.
