Dear Ms. Richards,
Enclosed are 3 signed permit renewal applications for the Wallace Regional Wastewater Treatment
plant (NC0003450). Our current permit expires at the end of this month, and I apologize for this
application being late. We had contracted our engineer to submit the application and look at an
expansion request at the same time and he took longer than expected to return the form. At this time
we are asking for a renewal with no expansion of the WWTP.
If you need any more data for the application, my contact information is below.

2 Facilities that do not use chlorine for disinfection,do not use chlorine elsewhere in the treatment process,and have no reasonable potential to discharge chlorine in their effluent are not
required to report data for chlorine.
Chlorine results were not done by a certified lab as the WWTP is not field certified for
Chlorine. Testing was done for operational process control only and not per NPDES permit.
Disinfection by chlorine was only used when UV system was not operational due to storm
flooding.
