Dear Ms. Garrett:
Shield Engineering, Inc. (Shield) successfully collected stormwater samples for Stormwater Discharge
Outfalls SDO#001 and SDO #002 at the Cleveland facility for the month of September 2022. During the
September 30t'sampling event,Shield's field measurements of pH were 8.1 at SDO#001 and 7.4 at SDO
#002 .The analytical results of the stormwater samples collected during the qualifying storm event'are
attached to this cover letter. In addition,the Qualitative Monitoring Report(QMR)forms and the partially
completed Discharge Monitoring Report (DMR) forms are attached to this cover letter. The Qualitative
Monitoring Report for SDO#002 notes that stormwater is flowing around the rip-rap and not through the
rip-rap lined channel. The QMRs should be kept onsite. Analytical results from the sampling event show
an exceedance of Zinc at SDO#002.
Daimler's Cleveland facility has exited Tier Three at SDO#001 for Copper and is monitored on a quarterly
basis. The facility remains in Tier Three of the NPDES General Permit No. NCG030000 at SDO #002 for
Copper and Zinc.Shield greatly appreciates the opportunity to provide environmental services to Daimler
Truck North America. If you have any questions in reference to this document or require further
information, please feel free to contact undersigned at(704)394-6913.
