RE: NPDES Permit Issuance
Permit No. NC0086193
Mid South Water Systems-
Maplecrest Subdivision
Gaston County
Pursuant to our telephone conversation this morning, I am writing to provide you with several
technical type changes that need to be made to our permit referenced above. I do not understand
how we missed getting a draft but appreciate your willingness to work with us on this matter.
On the supplement to permit cover sheet, item 1 begins with "Continue to discharge filter
backwash ...". There has been no discharge so the "change to" needs to be deleted.
In section A(1). Effluent Limitations and Monitoring Requirements - Final, the Flow (MGD)
measurement frequency is listed as weekly. This needs to be changed to Quarterly since the flow
per day is considerably less than 5000 gallons.
At well site No. 2 (outfall 002) there does not need to be an upstream measurement of discharge.
Thank you for taking care of these matters for us.
Sincerely,
MID SOUTH WATER SYSTEMS, INC
