Stormwater Permit No. SW6191101
SOF Combat Medical Training Facility PN# 85958

Dear Mr. Sesler:
The Division of Energy, Mineral and Land Resources (DEMLR), received a Stormwater
Management Permit Application for the subject project on November 18, 2019. A review of that
information has determined that the application is not complete. The following information is
needed to continue the stormwater review:
Please use "Directorate of Public Works" as the applicant for this project (Section III,
1 a).
2. The stream running parallel to Bastogne Drive, east of the proposed building, is shown on
the most recent USGS topographic map and a portion of it appears to be within the
project area. Please...
a. Include this area in Section IV, 6,
b. Recalculate Section IV, 7 & 8 to accommodate this area,
c. Delineate this area on the plans (Section VI, 8h), and
d. Show the associated buffer on the plans (Section VI, 8p).
3. Please provide an original, signed Supplement-EZ Form (Section V & Section VI, 3).
4. It is noted that some sections of the BUA are dimensioned on the plans, however the
values in the calculations, application, and Supplement-EZ Form should be verifiable
using just the plans (Since we don't have access to/require the CADD files). Please
include something on the plans (Like callouts, a table, etc...) so that the BUA values used
in the submission may be verified (Section VI, 8j).

5. It is noted that the stormwater management report contains a drainage area map for the
SCM, however Section VI lists requirements for the plan set. Please show the drainage
area to the SCM on the plans (Section VI, 8o).
6. Since this project will be using the Limit of Disturbance (LOD) as the project area, please
provide a plan sheet showing the full extent of the LOD.
7. Please correct the following issues with the Supplement-EZ Form:
a. Cover Page Sheet
i. Lines 7, 8, & 9 — Please provide these items.
b. Drainage Areas Sheet
i. General
1. Line 15 — This item should only be used if there is a net decrease
in total BUA from existing conditions to proposed conditions.
ii. Drainage Area 1
1. Line 7 — Please include this item. This item is the sum of the items
listed in line 10.
c. Infiltration System Sheet
i. Lines 2 & 44 — Use the design volume (Based on the design storm, 1") for
these items instead of the volume that the facility can hold.
ii. Lines 12, 13, & 25 — Please indicate that these items are not applicable
(N/A).
iii. Line 20 — Please elaborate in the additional information section what type
of pretreatment is being used for this facility.
iv. Line 45 — Calculate this value based on the design volume instead of the
volume that the facility can hold.
8. 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:
https://edocs.deq.nc.gov/Forms/SW Project Submittal
While it is not required, it is recommended that better pretreatment for fine particles is
incorporated int the design. While the provided pretreatment does screen out large (> 3/8")
refuse, fine particles can still enter the facility and clog up the infiltration media, necessitating
more frequent maintenance.
Please note that this request for additional information is in response to a preliminary review.
The requested information should be received by this Office prior to January 17, 2020, or
the application will be returned as incomplete. The return of a project will necessitate
resubmittal of all required items, including the application fee. Please reference the State
assigned project number SW6191101 on all correspondence.
If you need additional time to submit the information, please submit your request for a time
extension to the Division at the contact below. The request must indicate the date by which you
expect to submit the required information. The Division is allowed 90 days from the receipt of
a completed application to issue the permit.

The construction of any impervious surfaces, other than a construction entrance under an
approved Sedimentation Erosion Control Plan, is a violation of NCGS 143-215.1 and is subject
to enforcement action pursuant to NCGS 143-215.6A.
If you have any questions concerning this matter please feel free to contact me at
[e-mail] or [phone].
