Dear Ms. McGrath:
ROY COOPER
Governor
MICHAEL S. REGAN
Secretary
S. DANIEL SMITH
Interim Director
"hhe Mooresville Regional Office staff have reviewed your April 11, 2019 request for a determination that
stormwater discharge outfall 2 be granted representative outfall status for stormwater outfalls l and 3. Based on
the information provided and an April 11, 2019 site inspection by MRO staff, we are approving this request. In
accordance with 40 CFR § 122.21(g)(7), you are authorized to sample outfall number 2 as representative for the
entire site. This approval is effective with the next sampling event.
Please append this letter to your Stormwater Pollution Prevention Plan (SPPP) or permit to document that
representative outfall status has been approved. If changes in drainage areas, structures, processes, storage
practices, or other activities occur that significantly after the basis of this approval, representative outfall status
may no longer be valid. You should either resume sampling at all SDOs, or reapply to this office for
representative outfall status based on updated information. If you have any questions or comments concerning
this letter, please contact our office at [phone].
Sincerely,
Zahid S. Khan, CPM, CPESC, CPSWQ

- Day,
If a facility is required to sample multiple discharge locations with very simi'larstormwater dlscharges, the
permittee may petition the Director for Representative Outfoll Status (ROS). DEQ may grant Representative
OutfallStatus if stormwater. discharges from a single outfall are representative of discharges from multiple
outfalls. Approved ROS will reduce the number of outfalls where analYti[al sampling requirements apply.
If Representative Outfall Status is granted, ALL outfalls arestill subject to the qualitative monitoring
requirements of the fccfllty's permit —unless otherwise allowed by the permit (such as NC602000a) and DEQ
approval. The approval letter from DEQ must be kept an site with the facility's Stormwater Pollution
Prevention Plan. The fadllfty must notift,.DEQ in writing1fanychanges affect-representative,status.
