Subject: NPDES Permit Renewal Application
Hoffer Water Treatment Facility Water Quality
NPDES Permit#NC0076783 Permitting Section
To Whom It May Concern:
Enclosed please find the NPDES permit renewal application (Short Form C - WTP) and a brief narrative found in
this cover letter explaining the management plan for the Hoffer Water Treatment Facility(WTF),which is located in
Cumberland County. The current NPDES permit, NC0076783, was issued on August I, 2015 and expires at
midnight on October 31,2016.
The wastewater to be discharged is supernatant from a settling lagoon. The waste streams discharged to the lagoon
include residuals from filter backwash water and sedimentation basins. Prior to entering the lagoon, the wastewater
is treated by way of physical/chemical processes utilizing, polymer addition and clarification. The clarification
process involves thickening the residuals to approximately 2.5% solids. The thickened ferric residuals are then
pumped to the Cross Creek Water Reclamation Facility for further treatment to include mixing with bio-solids prior
to land application and the supernatant from the thickening process is discharged to the settling lagoon.
All of the requested material is enclosed with the exception of a solids handling plan. Due to the nature of our
process as described above, we do not have a solids handling plan for the water treatment plant. As stated above,
solids generated from the thickening process are blended with biosolids from the Cross Creek Water Reclamation
Facility and disposed of on permitted land application sites. When the lagoon is cleaned, a dredge is used to remove
solids from the lagoon and those solids are also land applied through the PWC biosolids land application program.
If you have any questions regarding this application, you may contact me at 910-223-4733, or via email at
[e-mail].
Sincerely,
Public Works Commission
