Midrex Technologies, Inc. has requested approval of the following two chemicals, 3D TRASAR 3DT289 &
STABREX ST70. These products will be discharged into Outfall 001 & in to Sugar Creek.
Calculations predict the use of these products, 3D TRASAR 3DT289 & STABREX ST70, at the stated dosage
rates, will not cause toxic impacts to aquatic life in the receiving stream, Sugar Creek. Therefore, the use of
these products as an additive to their cooling water system at Midrex Technologies, Inc. is acceptable.
