Representative Outfall Status Request

Dear Major Ingram:
Dee Freeman
Secretary
The Mooresville Regional Office staff have reviewed your request received on March 16, 2010, for a
determination that stormwater discharge outfall (SDO) 005 be granted representative outfall status for
stormwater outfalls 001, 002, 003, and 004. Based on the information and maps provided and the site
visit of February 3, 2010, we are approving this request. In accordance with 40 CFR §122.21(g)(7), you
are authorized to sample outfall number 005 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 SDOs, regardless of representative 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 SDO 005,
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 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,
Matt Matthews
Section Chief
