Dear Mr. Heimeshoff:
ROY COOPER
Governor
MICHAEL S. REGAN
Secretary
WILLIAM E. (TOBY) VINSON, JR.
interim Director
On August 6, 2018, the Wilmington Regional Office of the Division of Energy, Mineral and Land
Resources received and accepted a complete minor modification application for changes to the approved
plans for Stormwater Management Permit Number SW8 160501. It has been determined that the nature
of the proposed change meets the definition of a minor modification in that it does not result in an
increase in the size of the permitted stormwater control measure (SCM) and does not increase the amount
of built -upon area. Please refer to Attachment 1 for a detailed description of the current proposed minor
modification and a list of all the past modifications approved during the effective period of the permit.
We are forwarding you an approved copy of the modified plans for your files. Please add the attached
plans to the previously approved plan set. Please replace the previously issued permit with the revised
permit, dated August 10, 2018, attached. This revised permit does not impose new or different terms; it
merely restates some of the previous terms to provide you with a better understanding of your obligations
under the permit.
Please be aware that all terms and conditions of the permit issued on November 7, 2016, remain in full
force and effect, including the requirement to recorded deed restrictions with the built -upon area
allocations. Please also understand that the approval of this minor modification to the subject State
Stormwater Permit is done on a case -by -case basis. Any other changes to this project must be approved
through this Office prior to construction. The approval of this minor modification does not preclude the
permittee from complying with all other applicable statutes, rules, regulations or ordinances which may
have jurisdiction over the proposed activity, and obtaining a permit or approval prior to construction.
If you have any questions concerning this matter, please do not hesitate to call me at [phone] or
via email at [e-mail].
Sincerely,
k
Christine Hall
Environmental Engineer

Wet Detentlon .oyad
The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the vegetated filter if one
is provided.
Important maintenance procedures:
_ Immediately after the wet detention basin is established, the plants on the vegetated shelf and perimeter of the
basin should be watered twice weekly if needed, until the plants become established (commonly six weeks).
No portion of the wet detention pond should be fertilized after the first initial fertilization that is required to
establish the plants on the vegetated shelf.
Stable groundcover should be maintained in the drainage area to reduce the sediment load to the wet detention
basin.
If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment through the
- emergency drain should be minimized to the maximum extent practical.
- Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month and within 24 hours after every storm event

Dear Christine Hall:
Bohler Engineering is pleased to submit on behalf of Wal-Mart .Real Estate Business trust, the revised
Stormwater Management As -Built calculations and associated documentation for Walmart Swansboro
located at 121 W. Corbett Ave., Swansboro, Onslow County, NC. The following is our comment
response letter addressing comments received from the NCDEQ Environmental Quality Division dated
July 13, 2018. Each comment is addressed and responded to as follows:
Minor Modification Review Comments
Comment 1A: Additional rows were provided in the stage -storage tables. However, these tables still
exclude the forebay surface area at the vegetated shelf bottom elevation. Although a
vegetated shelf may not be provided in the forebays, there is still a surface area associated
with that elevation. Please include the forebay surface area at the vegetated shelf bottom
elevation in the forebay stage -storage tables.
Response IA: Forebay surface area at the vegetated shelf bottom elevation provided in stage -storage
tables.
Comment 1B: Additional information was provided demonstrating how the average depths were
determined using the Option 2 calculation. The surface area at the elevation of the
bottom of the vegetated shelf used in this calculation excluded the forebay surface area at
this elevation. In Option 2, the surface area at the bottom of the vegetated shelf is
considered to include both the main pond and the forebay. Please include the forebay
surface area at the vegetated shelf bottom elevation in the average depth calculations
Response 1R: Forebay surface area at the vegetated shelf bottom elevation provided in the aver• ge
depth calculation.

Comment Response Letter
Page 2 of 2
Comment 2: 15A NCAC 02H.1003(g)(7) effective September 1, 1995: The provided storage volume
shown in
the revised stage -storage tables are based on the nearest whole or rounded elevation for both the
permanent pool elevation and the temporary pool elevation. Please demonstrate the amount of
storage volume provided between the provided permanent pool elevation and the provided
temporary pool elevation without rounding to the nearest elevation.
Response 2: Storage volume provided between permanent pool elevation and temporary pool
elevation provided accurately in the wet detention basin supplement.
Comment 3: 15A NCAC 02H.1008(e)(6) effective September 1, 1995, .1008(h), and the 2007 BMP
manual:
In response to Item 3 of the previous request for additional information, it was confirmed that the
forebays provided for Ponds 1, 2, and 3 are smaller than the recommended range of 18-22%. The
response continues to indicate that the forebays are all in compliance with the alternative design
criteria found in 15A NCAC 02H.1008(h). The response also notes that the ponds meet the 85%
TSS removal and drawdown time requirements; however, these are separate requirements of 15A
NCAC 02H. 1008(e) and are not directly related to the purpose of a forebay. Please provide
additional details or justification demonstrating how the provided forebays provide equal or better
stormwater control, equal or better protection of waters of the state, and result in no increased
potential for nuisance conditions. The justification should consider the purpose of the forebays,
which is to enhance sedimentation at the inlet of the pond
Response 3: Per conversations with Christin Hall in July, 2018, it was acceptable to observe the
bottom elevation of the main pool above the elevation that was surveyed, in order to
meet forebay minimum volume requirement between 18-22% of the total permanent
pool volume. This alteration also considers new SAIDA ratios and required SA for all
Ponds affected. Using this method, all (3) ponds are now between 18-22% of total
permanent pool volume as per code requirement. See calculations on stage -storage
tables.
Should you have any questions regarding this project or require additional information, please do not
hesitate to contact me at [phone].

Secondary BMP/SCM Analysis:
The level spreader and vegetated filter strip, as well as the infiltration trenches downstream of Ponds 2
and 3, are constructed of approximately the same dimensions and intent as the designed facilities. The
infiltration areas shown on the survey were approximated based on the original stakeout locations of the
trenches from the design plans. Due to field conditions and proximity to wetlands, the vegetated filter
strip's shape was altered to provide approximately the same filtering area.
Based on our review of the signed and sealed surveys provided to Bohler by John L Pierce and Associates
Land Surveying, the constructed stormwater control measures meet the NCDEQ requirements from the
time of permitting and approval.
All supporting calculations have been provided in the appendix section of this memorandum.

Tony,
I looked at the files sent on Monday, July 30th, and noticed the updated calculations are 60+ pages long. I'm not able to
print out that many pages. I also didn't see an updated page for the O&M agreement, which I'm assuming also should
have changed based on your email that the elevation considered to be the pond bottom has changed.
Did you / can you also mail hard copies?

Good morning Christine,
I realize you are probably very busy with other projects this week. If possible, could you just confirm you received this
resubmission of documents for Walmart Swansboro and that we have met the resubmission deadline of 7/31?
Have a great day!

Christine,
As requested, see attached required additional information needed for as -built review.
• Per earlier conversations with NCDEQ, it was generally acceptable to observe the main pool bottom of pond
elevations higher than what was surveyed. This approach was followed, in order to show forebay to total
permanent pool volume ratios for Ponds 1, 2 and 3 are between the required 18-22%. All applicable calculations
and tables have been updated accordingly. Using this method, all forebay volumes were able to meet the
requirement, satisfying the previous comment #3.
Please let us know if there is anything else we can provide for you at this time.
Thanks!

All,
I have had a chance to review the items received on June 22"d for the subject project. There are still a few items that
weren't completely addressed and such that additional information is needed. Typically only 2 requests for additional
information are permitted before returning the application. However, I have received approval to allow a third addinfo
this time for this submittal since the package is almost complete. Please let me know if you have any questions or wish
to discuss these items.

Morning! Per your last email — we are trying to track down information from Walmart and the GC actively/on a weekly

Could we have until the end of May to resubmit? We are honestly doing everything in our powerto track down
recording information for the outparcels/O+M agreement, and pushing the GC to complete the field work needed, but it
is not a quick process.

Dear Mr. Heimeshoff
ROY COOPER
Governor
MICHAEL S. REGAN
Secretary
WILLIAM E. (TOBY) VINSON, JR.
Interim Director
The Wilmington Regional Office received and accepted a minor modification to the State Stormwater
Management Permit for the subject project on February 7, 2018 with additional information received on
May 29, 2018 and again on June 22, 2018. A preliminary in-depth review of that information has
determined that the application is not complete and that additional information is needed. To continue the
minor modification review, please provide the following additional information:
15A NCAC 02H.1008(e)(10) effective September 1, 1995 and Recommendation per Figure 10-
2b and Section 10.3.4 of the 2007 BMP manual: In response to Item 1 of the request for
additional information dated June 4, 2018,
a. Additional rows were provided in the stage -storage tables. However, these tables still
exclude the forebay surface area at the vegetated shelf bottom elevation. Although a
vegetated shelf may not be provided in the forebays, there is still a surface area associated
with that elevation. Please include the forebay surface area at the vegetated shelf bottom
elevation in the forebay stage -storage tables.
b. Additional information was provided demonstrating how the average depths were
determined using the Option 2 calculation. The surface area at the elevation of the
bottom of the vegetated shelf used in this calculation excluded the forebay surface area at
this elevation. In Option 2, the surface area at the bottom of the vegetated shelf is
considered to include both the main pond and the forebay. Please include the forebay
/ surface area at the vegetated shelf bottom elevation in the average depth calculations.
1I2. 15A NCAC 02H.1003(g)(7) effective September 1, 1995: The provided storage volume shown in
the revised stage -storage tables are based on the nearest whole or rounded elevation for both the
permanent pool elevation and the temporary pool elevation. Please demonstrate the amount of
storage volume provided between the provided permanent pool elevation and the provided
temporary pool elevation without rounding to the nearest elevation. /
15A NCAC 02H. 1 008(e)(6) effective September 1, 1995, .1008(h), and the 2007 BMP manual:
In response to Item 3 of the previous request for additional information, it was confirmed that the
forebays provided for Ponds 1, 2, and 3 are smaller than the recommended range of 18-22%. The
response continues to indicate that the forebays are all in compliance with the alternative design
criteria found in 1 SA NCAC 02H.1008(h). The response also notes that the ponds meet the 85%
TSS removal and drawdown time requirements; however, these are separate requirements of 15A
NCAC 02H.1008(e) and are not directly related to the purpose of a forebay. Please provide
additional details or justification demonstrating how the provided forebays provide equal or better
stormwater control, equal or better protection of waters of the state, and result in no increased
potential for nuisance conditions. The justif cation should consider the purpose of the forebays,
which is to enhance sedimentation at the inlet of the pond.

Please remember to confirm that any revised information is presented consistently throughout the
application documents including calculations, supplements; narrative, and plans. Please also remember to
provide two hard copies of any updated documents per 15A N CAC 02H.1042(2).
The requested information should be received in this Office prior to July 31, 2018, 2018, or the
application will be returned as incomplete. Please note that typically only two letters requesting
additional information is allowed in the State Stormwater Program. Special permission was granted to
allow a third request for this project. 17 the information is not satisfactorily provided after this third
request, the project will be returned. If the project is returned and you wish to re -submit later, you will
need to resubmit all required items at that time.
If additional time is needed to submit the requested information please e-mail, mail, or fax your extension
request, prior to the original due date, to the Division using the contact information available in this letter.
The extension request must include a justification and a date of when the requested information will be
submitted to the Division. Please remember that extension requests delay the issuance of the final
permit. The Division is allowed 90 days from the receipt of a complete application to issue the permit.
Please reference the State assigned application number on all correspondence. If you have any questions
concerning this matter, please feel free to call me at [phone] or email me at
[e-mail].

Ce inment 3: 15A NCAC 02H. I 008(e)(6) effective September 1, 1995 and the 2007 BMP Manual: the
forebay for Pond 2 is listed as being 15.5%, which is less than the recommended 18-22%
range. Please provide justification for the deviation in accordance with 15A NCAC
02H.1008(h) effective September 1, 1995.
Response 3: In accordance with 15A NCAC 02K.1008(h), both requirements for 85% TSS removal
and drawdown time between 2 to 5 days, have been met for all 3 ponds, per As -Built
survey. Therefore, Pond 1, 2 and 3 forebays are all in compliance with "Alternative
Design Criteria." Pond 2 was previously approved with a forebay listed at 18.2%, and
met the "Alternative Design Criteria': See stormwater technical memo for pond
drawdown time for all 3 ponds.

Subject: FW: [External] School Street Center (SW8 121110) & Swansboro Walmart (SW8 160501)
Mr. Lanier,
The devil will be in the details for this. It will require at least two modifications (Walmart/SW8160501 & Sci tool Street
Center/SW8121110). But, Walmart is a subdivision and se if this change will impact any of the offsite parcols' permits
then those would have to be modified as well. Another thing to consider would be whether or not there is enough room
in the systems for SW8160301 & SW8 121110 to accommodate the change. (I am not sure if this is a 1:1 impervious
area exchange or not?) You will also need to consider if any changes are needed to the deed restrictions for Walmait.
The language that you are looking for to include in the deed will be determined during the permit reviews to modify the
various permits. The Swansboro Walmart (SW8 160501) is actually in-house and in review currently. My coworker,
Christine, is working on that one. The change they are making right now does not include the change for the access road
that you are describing, and so it would have to be issued and then it can b-- modified again. You will wart to modify the
various permits prior to exchanging the deeds so that all of this can be worked out. (It is actually required by Section
II(6) of your permit.)
6. The perrnittee shaft submit to the Uire ctor and shall hanrc roceived approval for
revised plans, specifications, and calculations prior to construdion, for any
modificabon to the approved plans, Including, but not i mited to, those listed
below:
a. Any rovftion to the approved plans, regardless of size.
b. Redesign or addition to the approved arnount of built -upon area.
c. Further subdivision, acquisition, or sale of all or part of the project area.
The project area Is defined as aN property owned by tho pormifteo for
which Sedimentation and Erosion Control Plan approval or a C.AW4 Major
permit was sought.
d. Filling in, altering, or piping of any vegetative conveyance shown on the
approves# plan.
If you have further questions, please let me know.

Subject: [External] SW8 121110 & WALMART (SWANSBORO) SW8 ?
Georgette,
I hope you can advise on this matter.
Attached is a recombination plat showing the tracts of land that will be exchanged between WAL-MAR and
(KCI) Keystone Contractors Inc.
The Swansboro Walmart store is open and an operating business. Walmart will extend Norris Rd to their site.
KCI will convey to WAL-MART a 0.46 acre tract for extending Norris Rd. The runoff from the 0.46 acre will be
treated by Walmart storm water facilities.
WAL-MART will convey KCI a 0.44 acre tract. The 0.44 acre tract will be recombined with the remaining
portion of the KCI tract located on the east side of the
the Norris Rd extended. It will have a total area of 0.83 acres tract. The runoff from the 0.83 acre tract will be
piped under Norris Rd. extended and will be treated by the SW8-12110 facility.
Can the Stormwater permits be modified so that each owner will be responsible for the treat their respective
runoff?
Deed will be exchanged soon and I would like advice/information for the language that can be put in the deed
that will meet the Division of Water Quality requirement and standards.
Any advice and recommendations would be appreciated.
Thank you,
Barden Lanier

C
The Wilmington Regional Office received and accepted a minor modification to the State Stormwater
Management Permit for the subject project on February 7, 2018 with additional information received on
May 29, 2018. A preliminary in-depth review of that information has determined that the application is
not complete and that additional information is needed. To continue the minor modification review,
please provide the following additional information:
L=' 1. 15A NCAC 02H.1008(e)(10) effective September 1, 1995 and Recommendation per Figure 10-
2b and Section 10.3.4 of the 2007 BMP manual: In referencing Option 2 shown in Figure 10-2b
of the BMP Manual revised 6/16/09, not enough information has been provided to support the
surface area at the bottom of the shelf (including both the main pond and forebay) for each of the
three ponds. The information presented appears to only use the main pond surface area at the
bottom of the vegetated shelf to determine the average depth. Please provide additional details in
the calculations or forebay stage -storage tables to support how the average depths were
determined.
2. 15A NCAC 02H.1003(g)(7) effective September 1, 1995:
�j a. Please provide additional details/rows in the stage storage tables to support the surface
areas and volumes presented in the supplement including, but not limited to, the
temporary and permanent pool at the elevations presented in the as -built surveys and
supplements. Calculations should be provided to support all information presented in the
supplements.
b. Pond 1: the total volume for the main pool in the stage -storage table does not appear to
be calculating correctly.
vC The engineering calculations and/or cover letter must be sealed, signed and dated. Please
provide a sealed, signed, and dated cover letter or other means to seal the calculations.
3. 15A NCAC 02H. I 008(e)(6) effective September 1, 1995 and the 2007 BMP manual: The
forebay for Pond 2 is listed as being 15.5%, which is less than the recommended 18-22% range.
Please provide justification for the deviation in accordance with 15A NCAC 02H.1008(h)
effective September 1, 1995.
L 15A NCAC 02H.1003(g)(8) effective September 1, 1995: A pdf of the re -signed operation and
maintenance form with corrected elevations was provided. Please provide the original signature.
Please remember to confirm that any revised information is presented consistently throughout the
application documents including calculations, supplements, narrative, and plans. Please also remember to
provide two hard copies of any updated documents per i 5A NCAC 02H.1v42(2).

BE # NCC138078
Bohler Engineering is pleased to submit on behalf of Wal-Mart Real Estate Business trust, the revised
Stormwater Management As -Built calculations and associated documentation for Walmart Swansboro
located at 121 W. Corbett Ave., Swansboro, Onslow County, NC. The following is our comment
response letter addressing comments received from the NCDEQ Environmental Quality Division dated
March 21, 2018. Each comment is addressed and responded to as follows:
Minor Modification Review Comments
Comment 1: Please submit the final deed listing Wal-Mart Real Estate Business Trust as the property
owner.
Response 1: Final deed will be provided prior to final approval.
Comment 2: The site inspection on February 20, 2018 found the trench drain installed along Pond 3
does not discharge into the collection system as approved. Instead, it discharges directly
into the main pool. This change is not shown on the revised plans submitted for the
minor modification. Please either redirect the trench drain discharge to the collection
system, as originally approved, or re-route the discharge to the forebay and document the
additional inlet on the revised plans.
Response 2: Pond 2 and Pond 3 trench drain discharge pipes have been redirected to their
respective forebays with 6" PVC underground pipes. As -built drawings are included
with this submittal for reference.
Comment 3A: The stage -storage table for Pond 1 appears to indicate that the main pool volume and
forebay volume include the sediment accumulation depth. Please demonstrate that the
wet detention pond has been designed to account for sufficient sediment storage to allow

NCDEQ — Christine Hall
Wal-Mart Supercenter #7179-000 - Swansboro
Stormwater Management Inspection
Comment Response Letter
Page 2 of 3
the proper operation and maintenance of the facility between scheduled clean outs and
the appropriate volumes have been considered.
Response 3A: Calculations made from current As -Built survey yield average pool depth of 10.54 feet
(not including sediment accumulation depth from elevation 12.00' to 13.00'). These
calculations are based on the average depth equation (NCDENR Stormwater BMP
Manual 06116109). 10.54 feet average pool depth accounts for sufficient sediment
storage to allow for proper operation and maintenance.
Comment 3B: The forebay bottom/top of the sediment storage for Pond 3 was approved at 15ft.;
however, the revised documents indicate this elevation is at 17ft. The revised plans show
the bottom of the forebay at 17ft. with no additional room for sediment storage. Please
confirm the intended bottom elevations and provide maintenance, as necessary..
Response 3B: Per As -Built drawings (dated 517118), bottom of forebay elevation is recorded as 17.0 ,
therefore top of sediment accumulation storage is observed to be at elevation 18.0 :.
Seepage 11 of Stormwater Technical Memo titled "Wet Pond #3 Design'; which show
the total forebay volume for Pond 3 is 16.8% of the main permanent pool volume (per
NCDEQ calculation method). This calculation was made excluding the sediment
accumulation volume between elevations 17.00' and 18.00
Comment 4A: The stage -storage tables do rot reflect these updated elevations. Also, the increments
presented in the stage -storage tables have changed. Please include accurate elevations in
the stage storage tables and include the surface areas for the bottom and top of the
vegetated shelf.
Response 4A: Updated stage -storage tables now reflect updated elevations. Elevations shown in the
stage -storage tables reflect the surface areas given in As -Built survey. Bottom and top
of vegetated shelf elevations have been provided, see stage -storage tables provided in
Stormwater technical memo.
Comment 413: For Pond 2, sum of the main pool and forebay surface areas at an elevation 29.25
(assumed to be 29.36) is 14,046 sf. However, the permanent pool surface area is
presented in the supplement as being 13,775 sf. Please confirm the surface area provided
at the permanent pool and that it is presented consistently.
Response 4B: Updated stage -storage tables now reflect updated elevations. Elevations shown in the
stage -storage tables reflect the surface areas given in As -Built survey. Bottom and top
of vegetated shelf elevations have been provided, see stage -storage tables provided in
stormwater technical memo.
Comment 4C: For Pond 2, please confirm the temporary storage volume provided. The incremental
volume between elevations 30 and 29.25 (likely should be 29.36) is greater than expected
based on the provided surface areas and depth.
Response 4C. Temporary storage volume of 29,445 sq. ft. is provided (per latest As -Built survey) at
elevation 31.05 feet (see sheet D-2 of previously approved plans for reference).
Incremental volume between elevations 30 and 29.25 are calculated per latest As -Built
survey.

Comment Response Letter
Page 3 of 3
Comment 4D: For Pond 2, the stage -storage table lists a different forebay volume than the supplement.
Please confirm.
Response 4D: Updated stage -storage tables now reflect updated supplement form, which are included
with this submission
Comment 4E: For Pond 2 and 3, the supplements indicate that the average depths were determined
using option 2. However, the resulting depths are lower than expected using this method.
Please confirm which method was used or provide additional details to support the
resulting average depth.
Response 4E. Average depth calculated for Pond 2 and 3 (using option 2) are 5 ft and 10.44 ft
respectively (see supplement forms included with submission). For Pond 3, 7.5 ft was
used in SAIDA calculation, as this is the maximum in the NCDEQ SAIDA table.
Comment 5: Include signed O&M form with convected elevations.
Response 5. Form will be provided prior to final approval.
Comment 6: Please remember to record deed restrictions and protective covenants prior to selling the
outlots and to submit a copy to the Division.
Response 6: Noted.

Dear Mr. Heimeshoff:
Property Owner:
John Pierce, Manager
Swansboro Investors, LLC
405 Johnson Boulevard
Jacksonville, NC 28540
The Wilmington Regional Office received and accepted a minor modification to the State Stormwater
Management Permit for the subject project on February 7, 2018. A preliminary in-depth review of that
information has determined that the application is not complete and that additional information is needed.
Additionally, a site inspection and file review was conducted on February 20, 2018 and found the site to
not be in compliance with the terms and conditions of the permit. Please find a copy of the completed
form entitled "Compliance Inspection Report" attached to this letter, which summarizes the findings of
the recent inspection. To continue the minor modification review, please provide the following additional
information:
V 1. Permit Condition II.7: Please submit the final deed listing Wal-Mart Real Estate Business Trust
as the property owner.
Ok 2. Permit Condition II.5 and II.17: The site inspection on February 20, 2018 found the trench drain
installed along Pond 3 does not discharge into the collection system as approved. Instead, it
discharges directly into the main pool. This change is not shown on the revised plans submitted
for the minor modification. Please either redirect the trench drain discharge to the collection
system, as originally approved, or re-route the discharge to the forebay and document the
additional inlet on the revised plans.
3. 15A NCAC 02H.1008(e)(10) effective September 1, 1995 and Recommendation per Figure 10-
2h and Section 10.3.4 of the 2007 BAP manual: The permanent pool volume is considered to he
between the permanent pool elevation and the top elevation of the sediment storage and does not
include the recommended minimum 1-foot sediment accumulation depth.
a. The stage -storage table for Pond 1 appears to indicate that the main pool volume and
forebay volume include the sediment accumulation depth. Please demonstrate that the
wet detention pond has been designed to account for sufficient sediment storage to allow
the proper operation and maintenance of the facility between scheduled clean outs and
the appropriate volumes have been considered.
b. The forebay bottom / top of the sediment storage for Pond 3 was approved at 15 ft;
however, the revised documents indicate this elevation is at 17 ft. The revised plans
show the bottom of the forebay at 17 ft with no additional room for sediment storage.
Please confirm the intended bottom elevations and provide maintenance, as necessary.

a. This minor modification was submitted to document the as -built elevations and surface
areas associated with the wet ponds, which changed slightly from the approved plans.
However, the stage -storage tables do not reflect these updated elevations. Also, the
increments presented in the stage -storage tables have changed. Please include accurate
elevations in the stage storage tables and include the surface areas for the bottom and top
of the vegetated shelf.
✓K. For Pond 2, the sum of the main pool and forebay surface areas at an elevation 29.25
(assumed to be 29.36) is 14,046 sq ft. However, the permanent pool surface area is
presented in the supplement as being 13,775 sq ft. Please confirm the surface area
provided at the permanent pool and that it is presented consistently.
LZ For Pond 2, please confirm the temporary storage volume provided. The incremental
volume between elevations 30 and 29.25 (likely should be 29.36) is greater than expected
based on the provided surface areas and depth.
d. For Pond 2, the stage -storage table lists a different forebay volume than the supplement.
Please confirm.
e. For Ponds 2 and 3, the supplements indicate that the average depths were determined
using option 2. However, the resulting average depths are lower than expected using this
method. Please confirm which method was used or provide additional details to support
the resulting average depth.
5. 15A NCAC 02H.1003(g)(8) effective September 1, 1995: Since the pond elevations have
changed from the approved condition, please provide an updated, signed operation and
maintenance form with corrected elevations.

Submission
Brett,
I have had a chance to review the provided technical memo. Based on the information included, the as -built condition
of the systems is less than the approved condition but greater than required. Since the systems are providing less than
the approved amount, a modification will need to be submitted to the Division to approve and, most importantly,
document the changes (per permit condition 11.7 and 15A NCAC 02H.1002(25)).
Assuming the overall size of the SCM is not increasing, this can be accomplished through a minor modification. The
minor modification form can be found here. Two sets of plans have already been provided for the as -built condition of
the ponds so please submit the completed and.signed minor modification form and any other changes to the submittal
documents including supplements, calculations, remaining plan sheets, etc for review. Please note that minor
modifications are free through the regular program.

Linda,
I've attached a technical memo that addresses the deviations from the design to the as -built condition. We've re -run all
of the routing, as well as all of the temporary and permanent pool calculations, with everything still meeting the
requirements (as they were when the project was permitted).
We will be sending this out today to your office to be reviewed with the record drawings, plats, and certifications that
we sent last week. Please let us know if you have any questions or need any additional information. Thanks and have a
great holiday!!

You'll probably need to be more specific in regard to what those deviations are. And, you will need to
provide us with calculations showing us that the permitted areas, volumes, elevations, and sizes have
been met.
