Subject: Representative Outfall Status Request
Grede II, LLC/American Axle & Manufacturing
NPDES Stormwater Permit NCS000255
Montgomery County
Dear Mr. Kurtz:
Staff with the Fayetteville Regional Office of the Division of Energy, Mineral and Land Resources (DEMLR) has reviewed
your request received on September 20, 2019 for a determination that stormwater discharge outfall (SDO) 001 be granted
representative outfall status for stormwater outfalls 002 and 003. Based on the information and site map provided as well
as a compliance inspection conducted on June 27, 2019, we are approving this request. In accordance with 40 CFR
§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. 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 SDO 001, 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that significantly alter the basis of this approval, representative outfall status is no longer valid.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 concerns, please contact me at [phone] or by e-mail at [e-mail].
Sincerely
Michael Lawyer, CPSWQ
