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? Unnamed stream in central portion of site ----> South Hyco Creek (Lake Roxboro)
To find the waterbody, please see the NC Surface Waterbody Classifications map at
https://deq.nc.gov/abouttd ivisions/water-resou rces/water-resou rces-science-data
Receiving water classification(s) for the waters: wS-ll, B; Haw
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-II 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.

*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 7Q 10 conditions in HQW waters (PNA and
SA waters are considered HQW by definition). You maybe required to contact USGS to obtain a 7Q10 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 & TMDLs, please see the Impaired Waters Map & TMDL map on
