(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 exceeded the benchmark threshold for COD this sampling period (January 2020). 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&D landfill will be starting operation soon and the permit modification application will also address this change. i DocuSign Envelope ID:66F2F9E9-76D4-444A-8A2E-33BEB2DDDFAF We are providing two 12) copies of the January 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.

'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.
