MONTHLY NPDES COMPLIANCE SUBMITTAL FOR MAY 2023
GREAT OAK LANDFILL, RANDOLPH COUNTY, NORTH CAROLINA
PERMIT NO. NCG120107
To Whom It May Concern,
Stormwater monitoring is performed at the Great Oak Landfill under Permit No. NCG120107. The purpose of this
correspondence is to provide Stormwater Discharge Monitoring Report (DMR)for May 2023. Monthly monitoring
was initiated following consecutive exceedances of the total suspended solids (TSS) and fecal coliform
benchmarks at outfalls SB-1, SB-2, SB-3, and SB-4. There was no discharge from any site outfall during a
qualifying storm event within a timeframe that would allow the submittal of the fecal coliform samples to the
laboratory so that analysis could be performed within the required hold time during the May 2023 monitoring
period.
If you have any questions or require any additional information, please contact us. We appreciate your assistance
with this project.
Sincerely,
WSP USA INC
