Representative Outfall Status Request
Moen Inc.
Lee County
Dear Ms. Briner:
The Raleigh Regional Office staff have reviewed your request dated September 25, 2017 for a
determination that stormwater discharge outfall OF -1 and OF -2 be granted representative outfall
status for stormwater outfalls OF -3 and OF -4. Based on the information, maps and the site visit we
are approving the request for representative outfall status but with the alternate outfalls OF -1 and
OF -3 being representative of OF -2 and OF -4. In accordance with 40 CFR §122.21(g)(7), you are
authorized to sample outfall number OF -1 and OF -3 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 outfalls, 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 be address for OF -1 as outlined in the tiered
regulatory relief letter dated December 19, 2017.
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 outfalls, or reapply to this office for representative outfall status based on updated
