The facility's certificate of coverage is NCG110012. • Mallard Creek WWTP (12400 US Highway 29 North,Charlotte, NC 28262). The facility's certificate of coverage is NCG110114. • McAlpine Creek WWTP (12704 Lancaster Highway, Pineville, NC 28134). The facility's certificate of coverage is NCG110010. • McDowell Creek WWTP (4901 Neck Road, Huntersville, NC 28078).

Below are tables that provide the coordinates for all stormwater discharge outfalls(SDOs)at each facility, including all Representative Outfalls outlined in the settlement agreement between CLTWater and DEMLR(dated 11/28/23). You will notice that the numbering of these outfalls may not be sequential as some outfalls were previously designated as unregulated many years ago. For consistency with our program, we have decided to maintain the numbering/naming convention from the past. Additionally,we have highlighted all of the SDOs that will require analytical data be collected and will need to be set up in the Stormwater eDMR system.
