NPDES Stormwater Permit NCGl00074
Burke County
Dear Mr. Hemmings:
Staff with the Asheville Regional Office of the Division of Energy, Mineral & Land Resources
has reviewed your request received on July 30, 2018 for a determination that stormwater
discharge outfall 2 be granted representative outfall status for stormwater outfalls 1 and 3.
Based on the information provided and the site inspection conducted on October 09, 2018,
representative outfall status is denied concerning outfall 1. However, we are approving the
request that outfall 2 be granted representative outfall status concerning outfall 3 (See
attached map).
In accordance with 40 CFR §122.21(g)(7), you are authorized to sample outfalls number 1
and 2 as representative outfalls. This approval is effective with the next sampling event.
Please be reminded that the permit requires Qualitative (visual) Monitoring to be
performed at all stormwater discharge outfalls, regardless of representative outfall status.
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 outfall 1 and 2, where appropriate.

Please append this letter to your Stormwater Pollution Prevention Plan (SPPP) 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alter the basis of this approval, representative outfall status is no longer valid. In that case,
you should 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 Isaiah Reed or myself at [phone].
