RE: Dennis & Sheri Medlin
Open Shelf Storage Facility — 2ND Submittal
Dear Jim:
The purpose of this letter is to respond to your review comments dated June 12, 2020, for the above
referenced project. Your comments and corresponding responses are summarized below:
Division of Energy, Mineral and Land Resources
1. Please ensure that the percent impervious area for the project is calculated correctly
(Section IV, 81. Per the Soil Weighted CN Values calculation pages in the stormwater
management report, there will be 5,54 acres (5.38 + 0 + 0.10 + 0.06) of BUA within the project
area in proposed conditions and the project area is shown as 9.59 acres, resulting in a
percent BUA of 58% whereas 63% is shown in the Application. Revise as needed for
correctness and consistency.
The numbers have been updated. We have separated the different bypass areas and their
corresponding impervious areas. The impervious for the entire property is 58% whereas
the impervious for what drains to the pond is 66%.
2. Per the NC Surface Water Classification Map, the receiving stream appears to be NeiRs
(Neals) Creek (Section IV, 10).
You are correct. This has been corrected.
3. The drainage area to the proposed wet pond is shown as 8.55 acres in Section IV, 10 of the
Application and Water Quality & Surface Area Calculation page whereas on plan sheet SW-02
and on the Soil Weighted CN Values page the drainage area is shown as 8.18 acres. Revise as
needed for correctness and consistency. The drainage area column of Section IV, 10 should
be an accounting of the entire drainage area to the proposed SCM.
8.18 acres to the pond is correct. This has been corrected.
4. Please break down the "Other" type of BUA for the drainage area in Section IV, 10. The
storage lots can be considered "On -site Parking" and the access road can be considered
"On -site Streets". Revise as needed for correctness and consistency.
This has been revised.

5. Please provide 2 signed, sealed, & dated copies of the plans (Section VI, 81. The provided
plans were not signed.
Revised plans are now signed.
It is noted that basic dimensioning for the BUA is provided on plan sheet C-02, however, the
information provided in the calculations and Application should be verifiable on the plan sets
(Section VI, 8i). Please either provide callouts showing the type and area of each BUA or a
BUA table similar to the one in Section IV, 10 of the Application. Also, the total BUA for the
site, as shown on plan sheet C-00 (177,643 sf) does not coincide with the rest of the
submission.
See revised site data table and application with reconciled values.
7. Please delineate the wetlands on the plans or provide a note stating that no wetlands exist.
Provide documentation of the qualifications and identity of the individual who made this
determination (Section VI, 8m).
We are requesting a letter from our environmental consultant documenting this and will
forward ASAP.
8. Please initial the items from Section VI, 9-11 if they are included in the submission.
See updated form.
9. Section IX is not required since the Applicant is the Property Owner. With your permission, I
will cross out this item in red pen on the original, signed copy. If that is not acceptable to
you, please provide revised original signature pages without Section IX signed.
That is fine. Thanks.
10. It does not appear that sufficient impervious area is being treated in the proposed SCM (15A
NCAC 02H .1002(43)). In order to meet the definition of runoff treatment, "the volume of
stormwater runoff generated from all of the built -upon area of a project at build -out... is
treated in one or more primary SCMs."
The only areas not treated are small portions of the entrance driveways in the current
and future configurations. The actual impervious area not collected (shown in bypass
area #3) is a programmed amount that will likely be reduced once that property is
developed.
11. The pond cross-section on plan sheet C-05 appears to have the bottom/sediment storage
top elevations for the main pool and forebay switched. Revise as needed for correctness and
consistency.
This has been corrected.
12. The cross -sectional area of the main pool at elevation 307 appears to be incorrect (Pond
Volumes calculation page). Revise as needed for correctness and consistency.
This has been corrected.
13. When calculating the volume of the main pool and the forebay, the sediment storage area
should not be included. Revise as needed for correctness and consistency.
Additional depth was provided at the pond to account for this_
14. The project narrative states that the project area is 6.32 acres whereas the Application
indicates that the project area is 9.59 acres. Revise as needed for correctness and
consistency.
The narrative has been revised to explain the total site including future development,
which is 9.59 ac.

15. The entrance of the forebay must be deeper than the exit of the forebay (Wet Pond MDC 5b)
and both the entrance and exit of the forebay must have at least 6 inches of sediment
storage (Wet Pond MDC 3). Both the entrance and exit of the forebay are located on the
"bottom" (not the sides) of the forebay. Please refer to Figure 5 in Part C-3 of the Design
Manual for clarification.
This has been adjusted.
16. The concrete riser detail on plan sheet C-05 shows the pond bottom elevation as 384.
This has been corrected,
17. Please correct the following issues with the Supplement-EZ Form:
a. Cover Page:
i. Lines 7-10 -Vegetated setbacks are only required from "blue line"
streams as shown on the USGS topographic map. Since there aren't any
on or around the project area, these items are not needed.
ii. Re-sign & seal the cover page. Make sure to provide the original hard
copy in the resubmission.
b. Drainage Area Page:
i. Entire Site Column:
1. The entire site column should be a listing of all of the BUA that
will exist within the project area post -construction.
2. Line 7 - This item should be a summation of the items of Line
10.
3. Line 10 - Ensure that these values correspond to the values and
types shown in Section IV, 10 of the Application.
4. Line 16 - Ensure that this item is calculated correctly and
corresponds to Section IV, 8 of the Application.
5, Lines 17-19 - These items are not required for the entire site
column.
ii. Drainage Area 1 Column:
1. The drainage area 1 column should be a listing of all of the BUA
that will exist within the drainage area to the proposed SCM
post -construction.
2. Lines 4, 5, 7, 10, & 16-19 should be filled out.
3. Line 19 - this should be either the "Simple" method, or the
"Discrete NRCS" method.
iii. Line 20 - "Future" BUA has its own line and should not be shown as
"Other".
Wet Pond Page:
i. Line 27 - Revise per earlier comment.
ii. Line 28 - Revise per earlier comment.
iii. Line 29 - Per the calculations, it appears that Equation 3 is used. Revise
as needed.
iv. Line 30 - If Equation 2 was used, this item is not needed.
v. Line 31 - If Equation 3 was used, please provide this item.
vi. Line 32 - Revise per earlier comment.
vii. Line 35 - The design volume should match Line 2 of the Wet Pond Page
and Line 18 of the drainage area 1 column of the Drainage Areas Page.
viii. Line 44 - Revise per earlier comment.
ix. Revise any other items that may change from addressing other issues.
These comments are addressed in the resubmittal.

18, 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:
htt P s: edacs.deq,nc.gov/Form /S PLn eet 5�4bmLittaL
Understood.
While it is no-t required, it is recommended that the depth of the forebay be increased to reduce the
chance of resuspending sediment and to reduce the frequency of required maintenance. It is also
recommended to consider utilizing an SCM more well suited to well drained soils, such as an
infiltration system or bioretention cell.
Acknowledged. Thank you.

Dear Mr. Curry:
The Division of Energy, Mineral and Land Resources (DEMLR), received a Stormwater
Management Permit Application for the subject project on May 5, 2020. A review of that
information has determined that the application is not complete. The following information is
needed to continue the stormwater review:
Please ensure that the percent impervious area for the project is calculated correctly
(Section IV, 8). Per the Soil Weighted CN Values calculation pages in the stormwater
management report, there will be 5.54 acres (5.38 + 0 + 0.10 + 0.06) of BUA within the
project area in proposed conditions and the project area is shown as 9.59 acres, resulting
in a percent BUA of 58% whereas 63% is shown in the Application. Revise as needed for
correctness and consistency.
2. Per the NC Surface Water Classification Map, the receiving stream appears to be Neills
(Neals) Creek (Section IV, 10).
3. The drainage area to the proposed wet pond is shown as 8.55 acres in Section IV, 10 of
the Application and Water Quality & Surface Area Calculation page whereas on plan
sheet SW-02 and on the Soil Weighted CN Values page the drainage area is shown as
8.18 acres. Revise as needed for correctness and consistency. The drainage area column
of Section IV, 10 should be an accounting of the entire drainage area to the proposed
