Subject: Request for Additional Information
Stormwater Permit No. SW5220101
Hardee's — Main Street
Franklin County
Dear Mr. Watson and Mr. Barnacascal:
The Division of Energy, Mineral and Land Resources (DEMLR), received a Stormwater
Management Permit Application for the subject project on January 20, 2022. A review of that
information has determined that the application is not complete. The following information is
needed to continue the stormwater review:
Please QA/QC the submission items prior to resubmitting the requested information for
this project. There were numerous inconsistencies in the submission materials noted
during the review and it was difficult to ascertain which values were the "correct" values.
This review was performed to the best of our abilities given the provided information.
2. The parcel areas shown on plan sheet C2.00 (1.72 ac for parcel 1 and 0.66 ac for parcel 2)
do not add up to the property area as shown in Section IV, 4 of the Application (2.07 ac)
or other sheets of the plan set (cover page, C1.00, etc...). Please revise as needed.
3. The provided purchase agreement lists Tommy E. Twitty as the seller of parcel 1 whereas
the provided property deed shows Mr. & Mrs. Floyd as the Property Owners. Please
clarify who owns the property and revise the Application and/or Purchase Agreement as
needed.

4. As noted in the administrative completeness review, the deed restrictions and protective
covenants have not yet been provided for this project. Please provide these documents as
they are required prior to issuing the permit.
5. Adding up the BUA types shown in Section IV, 10 of the Application and the Drainage
Area Page of the Supplement-EZ Form results in a total BUA within the drainage area of
61,958 sf (61,956 sf is shown as the total BUA). This might be a rounding error but
should be corrected.
6. There appears to be an issue with the temporary pool of the stormwater wetland. Please
revise as needed:
a. The temporary pool is shown at elevation 272.87 in the Supplement-EZ Form.
This results in a temporary storage volume of only 4,069 cf (a minimum design
volume of 4,967 cf is required for this drainage area) and the provided forebay
area (889 sf per the Supplement-EZ Form) is more than the allowable 15%
(Stormwater Wetland MDC 6) of the wetland surface area (5,740 sf per the
Supplement-EZ Form) [889 sf / 5,740 sf = 15.5%].
b. The temporary pool is at elevation 273.5 on plan sheet C9.02, as indicated by the
riser elevation. This results in a temporary pool ponding depth in excess of 15
inches (Stormwater Wetland MDC 1). The plans show the permanent pool at
elevation 272.0, but also show the drawdown orifice invert at elevation 271.5 so it
is unclear from the plans where the permanent pool surface elevation would be at,
but either of these elevations result in a temporary pool ponding depth in excess
of 15 inches.
c. The temporary pool is shown at elevation 273.25 per the calculations. This results
in a temporary storage volume of 5,954 cf.
7. As previously mentioned, plan sheet C9.02 shows the drawdown orifice invert at
elevation 271.5 which contradicts the shown permanent pool elevation of 272.0. Please
revise.
8. As designed, the stormwater wetland appears to short-circuit (Stormwater Wetland MDC
5). Incoming stormwater runoff enters the stormwater wetland at its midpoint and does
not utilize the entire provided stormwater wetland. Please revise (you may wish to direct
the stormwater runoff to the southwestern most deep pool, this would allow the
stormwater runoff to utilize the entire length of the stormwater wetland).
9. Per Stormwater Wetland MDC 6, the forebay area may not exceed 15% (and must be at
least 10%) of the wetland surface area. Per the provided information in the Supplement-
EZ Form and calculations, the forebay is about 15.5% of the wetland surface area. Please
revise.

10. Per Stormwater Wetland MDC 6, the entrance of the forebay must be deeper than the
forebay exit. The information provided in the plan sheets and the Supplement-EZ Form
does not indicate that this design requirement has been met. Please revise.
11. Per Stormwater Wetland MDC 8, the shallow water zone comprises the portions of the
stormwater wetland that are between zero and nine inches below the permanent pool. The
provided information only shows the shallow water zone as being six inches deep. Per
plan sheet C9.04, the shallow water zone is shown as having a top elevation of 272.0 (the
permanent pool elevation) and a bottom elevation of 271.5 (at which point, the deep pool
zone starts). The deep pool zones should only include the portions of the stormwater
wetland that are at or below elevation 271.25. Please revise.
12. Plan sheet C9.04 indicates that there are an insufficient number of plants planted in the
shallow water zone (Stormwater Wetland MDC 13). The information on this plans sheet
indicates that the shallow water zone is 2,594 sf (which contradicts the information
shown in the Supplement-EZ Form and calculations, 2,230 sf) and has a total of 563
plants (145 + 192 + 226) this results in only 43.4 plants per 200 sf (adding up the
provided areas for each plant in this zone adds up to 2,249 sf which is different than what
is shown elsewhere). Please revise.
13. Adding up the provided planting areas for each of the plants in the temporary inundation
zone (plan sheet C9.04) results in a total surface area of 2,052 sf which is different than
the total temporary inundation zone surface area shown (1,763 sf) which is also different
than the information shown in the Supplement-EZ Form and calculations, 2,066 sf.
Please revise.
14. Please clearly show in the main set of plans how the stormwater maintenance
access/easement connects to the public right-of-way (General MDC 8c & 9). It is noted
that the stormwater maintenance access/easement is shown on the plans, but it is unclear
how it connects to the public right-of-way.
15. The following issues were noted in the Supplement-EZ Form, Stormwater Wetland Page:
a. Line 1 — The drainage area number refers to the number that the drainage area is
assigned on the Drainage Area Page of the Supplement-EZ Form, not the area of
the drainage area in acres. Please revise.
b. Line 20 — Please answer this item.
c. Line 25 — As mentioned previously, a temporary pool surface elevation of 272.87
results in a temporary storage volume of only 4,069 cf per the stage storage table
which is insufficient for this drainage area. Revise as needed.
d. Line 26 — As mentioned previously, there is a discrepancy in the plans with regard
to the actual permanent pool elevation (permanent pool value shown vs.
drawdown orifice invert). Revise as needed.

e. Line 27 — As mentioned previously, the bottom of the shallow water zone must be
nine inches below the permanent pool elevation (per Stormwater Wetland MDC
8). Revise as needed.
f. Lines 28, 29, 43, & 44 — As mentioned previously, the forebay entrance must be
deeper (at a lower elevation) than the forebay exit. Revise as needed.
g. Line 32 — As previously mentioned, the calculations list the temporary inundation
zone area as 2,066 sf and plan sheet C9.04 lists this area as 1,763 sf. Revise as
needed.
h. Line 33 — As previously mentioned, the calculations list the shallow water zone
area as 2,230 sf and plan sheet C9.04 lists this area as 2,594 sf. Please ensure that
the entire shallow water zone (all portions of the wetland that are between zero
and nine inches below the permanent pool) is included in this area. Revise as
needed.
i. Lines 34 & 35 — As previously mentioned, please ensure that the shallow water
zone is not included in these areas.
j. Lines 31-39 — These items may need to be re -calculated in order to address the
above comments.
k. Line 38 — As previously mentioned, the provided forebay area (889 sf) is larger
than 15% of the total surface area of the wetland (5,740 sf). Revise as needed.
1. Lines 40 & 41 — These values will change based on the revised value of Line 25.
m. Line 42 — This value should not exceed 9 in per Stormwater Wetland MDC 8.
n. Line 53 — Please answer this item.
16. Please ensure that all of the files from the initial submission are electronically uploaded.
It appears as though only the items that were requested in my 12/28/21 administrative
completeness review email were uploaded. Items (such as the Supplement-EZ Form,
O&M Agreement Form, calculations, etc...) from the initial 12/21/21 submission were
not uploaded and are required to be.
17. Provide pdfs of all revisions, 2 hardcopies of revised plan sheets, 1 hardcopy of other
documents, and a response to comments letter briefly describing how the comments have
been addressed.
a. Pdfs must be uploaded using the form at:
https://edocs.deq.nc.gov/Forms/SW-Supplemental-Upload
b. Hard copies must be mailed or delivered to the following address:
i. For FedEx/UPS:
Jim Farkas

512 N. Salisbury Street, Office 640E
Raleigh, NC 27604
ii. For USPS:
Jim Farkas
1612 Mail Service Center
Raleigh, NC 27699-1612
iii. Hand Delivery:
Please reach out to me prior to hand delivering a submission to make
sure that I (or someone else in my group) will be able to receive the
submission. Do not leave the package in the foyer with the
security guard.
NOTE: Hard copies should not be sent to a Regional Office. Doing so
will delay the review process and the submission package may be lost
while being sent from the Regional Office to me in the Central Office.
While not required, the following items were noted during the review:
- The minimum recommended drainage area size for a stormwater wetland is 2 acres. This
helps ensure that the wetland remains wet throughout the year and that the plants remain
alive and healthy. You may wish to select acceptable plants that are drought tolerant, or
select a more appropriate SCM for the site.
- An emergency spillway for the SCM is recommended. It is noted that the SCM is
designed to handle the 100-year design storm however, in the event of a clog in the outlet
structure or extreme weather event, an emergency spillway can prevent an embankment
failure.
- You may wish to add a stage -storage table for the portions of the stormwater wetland that
are located below the permanent pool. This can help with verifying that the MDCs
relating to the zone sizing (Stormwater Wetland MDCs 6-9) have been met.
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 April 9, 2022, 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 SW5220101 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.
