Dear Mr. Hiatt,
Project No. 1913614622.303
Stormwater monitoring is performed at the Great Oak Landfill under Permit No. NCG120107. The purpose of this
correspondence is to provide the Stormwater Discharge Monitoring Report (DMR) for the first quarter of 2022.
Samples were collected from outfalls Pond-1, Pond-2 and Pond-3. Outfall Pond-2 had an exceedance of fecal
coliform. Outfalls Pond-1, Pond-2, and Pond-3 had exceedances of total suspended solids (TSS). Outfall Pond-4
did not discharge during the precipitation event.
If you have any questions or require any additional information, please contact us. We appreciate your assistance
with this project.
Sincerely,
