Please find attached the July 2021 Stormwater Quarterly Discharge Monitoring Report for the Duke
University Transportation Maintenance Garage. An analytical sample was taken at both stormwater discharge
outfalls on 718J2021. All analytical results were within range of or below benchmark values. We will continue
to monitor rainfall at the site in order to collect the next monthly sample at SDO2.
Thank you,
