Dear Reporting Section:
Please find attached the March 2021 monthly stormwater Discharge Monitoring Report for SD02 at the Duke

analytical results were within range of or below benchmark values. We will continue to monitor rainfall at the
site in order to collect another monthly sample at SD02 for analysis as soon as possible.
