The Division of Energy, Mineral and Land Resources (DEMLR), received a Stormwater Management

determined that the application is not complete. The following information is needed to continue the
stormwater review:
1. Provide a completed Supplement EZ form for each SCM; only the cover page was submitted.
This is available on our website at: https://deg.nc.gov/about/divisions/energy-mineral-land-

2. Revise the O&M Agreement:
Provide a completed O&M Agreement (with original signature) using the O&M EZ form;
only the cover page was submitted [MDC 11]. This is available on our website at:
https://deq.nc.gov/about/divisions/energy-mineral-land-resources/energy-mineral-
land-permit-guidance/stormwater-bmp-manual

Spencer is not listed for that LLC.
3. There are multiple plan sheets with the same sheet number, C-403.
4. Two different versions of SWU-101 were submitted signed by different people. Some listed as
LLC member/managers, some not.

The DA and BUA is not consistently shown between the talcs, plans, and SWU-101.
Revise the volume and SA talcs, and the DA map as needed to reflect any changes to
make these consistent.

a. The vegetated shelf slope on the plan view does not appear to scale to 6:1 (C-405).
The DA and BUA is not consistently shown between the talcs, plans, and SWU-101.
Revise the volume and SA talcs, and the DA map as needed to reflect any changes to
make these consistent.
The plans show a 1.5" orifice, but the talcs show 1.75".
7. Provide pdfs of all revisions, 2 hardcopies of revised plan sheets, and 1 hardcopy of other
documents. Pdfs must be uploaded using the form at:
