Representative Outfall Status Request
Alcami Corporation
New Hanover County
Dear Mr. Smith:
The Wilmington Regional Office staff of the Division of Energy, Mineral, and Land Resources has
reviewed your request for determination that Outfall1 be granted representative outfall status for
Outfalls 2 and 3. Based on Brian Lambe's site inspection on August 19, 2020, we are approving this
request. In accordance with 40 CFR §122.21(g)(7), you are authorized to sample Outfall 1 as the
representative outfall. This approval is effective with the next sampling event. However, this approval
is contingent on the following requirements:
(1) All outfalls, regardless of representative status, must have a cleared path and the right of way to
the outfall must be properly maintained.
(2) The permit still requires that Qualitative Monitoring be performed at all Stormwater Discharge
Outfalls, regardless of representative status.
In addition, please remember that any actions you initiate in response to benchmark exceedences as
directed in the tiered response provisions of your permit must address all drainage areas represented by
Outfall 1, where appropriate.
Please append this letter to your Stormwater Pollution Prevention Plan 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 storm
water discharge outfalls, or reapply to this office for representative outfall status based on updated
information.
If you have any questions or concerns concerning this letter and the attached report, please contact Dan
Sams or me at [phone].
Sincerely,
FU44 zaf&
