Subject: Request for Additional Information
Modification Application
NPDES Permit NC0049778
Southern Pines WTP
Moore County
On August 1, 2014, the Division of Water Resources (DWR) issued a General Permit NPDES permit
(NCG590000) for wastewaters from Greensand and Conventional type water treatment plants. This
permit was' developed -to expedite the issuance and reissuance of these types of permits.
The Town of Southern Pines's existing Individual NPDES permit for its Southern Pines Water Treatment
Plant (WTP) is up for modification and qualifies for coverage under this new General Permit. The annual
permit fee for the general permit is $100 verses $860 for an Individual permit and monitoring is less
frequent than that listed in your current permit.
Similar to Individual NPDES permits; general permits expire every five years but can be renewed by
completing a short and simple general permit renewal. form. The General Permit is reissued every five
years and is sent to all the Permittees covered under it, all at the same time.
To switch to the General permit, the Town will need to make a written request to DWR. Please note, the
issuance of the General Permit would require. the recession of your individual permit. The Division
suggests that you review the attached file containing the General Permit NCG590000 and decide whether
you would like the Division to modify the individual permit or proceed with issuance of the General
permit via a Certificate of Coverage for the WTP. Note that the Town of Southern Pines operates a
conventional water treatment system that discharges to freshwater, so the facility would be subject to the
limitations listed on page 5 (B. (3.) Conventional WTP Effluent Limitations and Monitoring
Requirements — Discharging to Freshwater) in the attached General permit.
To request that the Division proceed with 'issuing the General Permit instead of modifying the existing
Individual permit, the Town should respond with something like the following:
The Town of Southern Pines has reviewed the Division of Water Resources General
Permit NCG5900000 for greensand and conventional type water treatment plants and
requests thatthe discharge from the Southern Pines WTP be covered under this new
general permit. The Town understands that the Division will rescind the individual
NPDES permit for the Southern Pines WTP — NC0049778 when the Certificate of
Coverage for the General Permit NCG590000 is issued to the Town for the WTP.
