Mr. Van Gelder:
The Raleigh Regional Office staff have reviewed your request dated June 3, 2018 for a
determination that stormwater discharge outfall (SDO) 001 be granted representative outfall
status for stormwater outfalls 002, 003 & 004. Based on the information and maps provided
and the site visits by Thad Valentine, we are approving this request. In accordance with 40 CER
§122.21(g)(7), you are authorized to sample outfall number 001 as a representative outfall.
This approval is effective with the next sampling event. We also want to remind you that the
permit still requires qualitative Monitoring be performed at all SDO's, regardless of
representative status. Additionally the outfall observed that drains from the new products
storage area that was not depicted on the site map should be added to the site map and
qualitative data should be taken with the other outfalls.
Please remember that any actions you initiate in response to benchmark exceedances as
directed in the tiered response provisions of your permit must address all drainage areas
represented by SDO 001, where appropriate.
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 alter the
basis of this approval, representative outfall status may no longer be valid. You should either
