RE: Application NPDES General-Permit NCG500000- Riley Technologies LLC.
Dear Mr. Hennessy,
Riley Technologies is applying for a NPDES General-Permit NCG500000 for non-contact
cooling water to be directly discharged into the local Stormwater Sewer System, the
completed permit form and relevant information is attached.
Riley Technologies LLC. is an automotive engineering, manufacturing and race team facility.
The composite manufacturing department requires the permit for an autoclave oven used in
the manufacture of CFRP components. The discharge is clean, non-contaminated, non-
contact cooling water from this oven. Clean fresh water is used to cool the oven, there are no
chemical additives introduced to it at any stage and clean water is discharged.
The discharged cooling water from the oven is received by the Town of Mooresville Municipal
Stormwater Sewer System closest to the exit point on the building (see diagrams included).
Alternatives to Direct Discharge would be costly and disruptive to our property. Connection
to Municipal or Regional Sewer Collection would require additional plumbing and tear up
road surfaces. Subsurface disposal and Spray irrigation are possible options however these
would also be costly and require additional plumbing and disruption to the site.
Please let me know if you need any further information or clarification on any points.
Sincerely,
Christian Rushforth
General Manager
Riley Technologies, LLC.
