Discharge Points Receiving Waters & Wetlands:
19) Receiving waters:
What is the name of the body or bodies of water (creek, stream, river, lake, etc.) that the facility stormwater
and/or wastewater discharges will end up in? Upper Little River
To find the waterbody, please see the "MAPS" tab on http://portal.ncdenr.org/web/wq,for a map of NC
Surface Waterbody Classifications.
Receiving water classification(s) for the waters:
If the site will discharge to a separate storm sewer system, name the operator of the separate storm sewer
system (e.g. City of Raleigh municipal storm sewer).
Discharge of Wastewater to receiving waters classified as WS-11 through WS-V, or SA, must be
approved by the Division of Water Resources (DWR) or Division of Marine Fisheries
(DMF). DEMLR cannot grant coverage under NCG020000 without that approval. Also be advised that
no new discharges of Wastewater are permitted in receiving waters classified as WS-1 or
freshwater ORW. Wastewater discharges to saltwater ORW will not be approved under General Permit
NCG02 but may be eligible for an individual permit.

21) Will this mine site discharge wastewater or stormwater to waters classified as Shellfish (SA) waters?
X No
❑ Yes, SA'
"For questions 19-20, be advised that the NCG02 General Permit limits the discharge volume of total combined
wastewaters to 50 percent of the receiving water in -stream flow under 7010 conditions in HOW waters (PNA and
SA waters are considered HQW by definition). You may be required to contact USGS to obtain a 7010 flow.
22) Will this mine site discharge wastewater or stormwater to impaired waters, or to waters with an
approved "Total Maximum Daily Load" (TMDL)?
To find impaired waters, please see the "Impaired Waters" map on the "MAPS" tab on
http://Portal.ncdenr.org/web/wq.
To find approved TMDLs in North Carolina, please see DWR's Water Planning Section website:
