Permit No. SW8 960329
The drainage area for Pond J includes 35,304 square feet of drainage area and the
associated impervious area which is a portion of the area that has been previously
permitted under the low density portion of the Base Entry Point and Road permit (SW8
090630) that could not be routed around the collection system. The permit for SW8
090630 appears to have been modified on May 29, 2012 to include the additional built -
upon area. Since this area is covered under both this permit; SW8 960329: and SW8
090630 any future improvements within the affected area will impact both permits.
4. The drainage area labeled "2017 Redevelopment' is exempted from State Stormwater
permitting requirements under the following conditions:
a. The project must be constructed as shown on the plans submitted to this Office,
b. The total proposed built -upon area of 52,718 square feet does not exceed the
existing built -upon area of 52,718 square feet: and,
c. The proposed stormwater control, sheet flow over vegetated areas, provides
equal protection of surface waters as the existing stormwater control, which is
sheet flow over vegetated areas.
5. The additional infiltration areas located prior to the pond and as shown on the plans has
not been demonstrated to meet State Stormwater BMP design requirements and
therefore is not considered a part of the approved state stormwater treatment system.
These additional measures are incorporated only by reference and are not enforceable
parts of the permit.
6. A 50 foot wide vegetative buffer must be provided adjacent impounded structures,
streams, rivers and tidal waters.
7. The wet detention ponds and infiltration basin do not require a vegetated filter strip.
8. The tract will be limited to the amount of impervious area indicated on the application
and in Sections 1,2; 1.10, and 1.11 of this permit; and per approved plans. The built -upon
area for future development within the drainage areas labeled J and "2017
Redevelopment' is limited to 10,000 and 5,730 square feet, respectively. Within the
other drainage areas, there is no impervious area allocated for the future development.
9. All stormwater collection and treatment systems must be located in either dedicated
common areas or recorded easements. The final plats for the project will be recorded
showing all such required easements, in accordance with the approved plans.
10. The runoff from all impervious areas within the permitted drainage areas of this project
must be directed into the permitted stormwater control system within drainage areas
labeled East (or G), West (or H); A, B, C, D, E, F, and J.

I have a couple questions on the supplement:
General MDC rig — Is the infiltration system really located on or near contaminated soils? If so, please add to the
additional information comment at the bottom, that this was a previously permitted system that is being expanded.
Infiltraiton MDC i#5 — Pending depth is listed as being 24 inches (or 17 ft), but I thought the overflow was set at 16.35 ft?
(16.35 —15.0 = 1.35 ft or 16.2 inches) Please confirm the ponding depth.

One more thing.... As I was drafting the permit, I noticed that the BUA allocations for DA J is different than approved in
2012. For instance: the amount of future previously approved was 10,000 sq ft; however this application lists the future
as being 21,230 sq ft. Why is the BUA allocation in DA1 changing?

Beth,
I just pulled this project out to take a look and realized that the supplement is missing its SCM specific pages. Once the
number of SCMs is completed on the cover page, the form needs to be refreshed to bring up the applicable number of
forms based on the number of SCMs IDed. (similar to the 0&M EZ form). Can you e-mail me the completed Infiltration
page? In the meantime, I'll go through the rest of the items.

I'm sorry I didn't respond sooner. Thanks for making those minor changes. For item 2, 1 can use the 0&M that you had
already submitted. I just need the supplement-EZ and any changes needed for the calculations.

For Items la. and 1b. I have corrected (see attached — two items).
4

For Item 2: We will not qualify under .1001(5). Based on the data recorded in the original permit and my calcs,
I believe we comply with .1050 and .1051. It appears that I need to submit Supplement Form EZ. Do I need to
submit the accompanying 0 & M Agreement form?

Kevin,
I had a chance to review the major modification to the subject project and found two minor items and one potentially .
larger item:
1. 15A NCAC 02H.1042(2)(a)(iv):
a. The sum of the drainage areas presented in Section IV.10 of the application and the attached table
exceeds the property / project area presented in IVA and 7. Please confirm the property / project area
listed in IVA and 7 of the application is consistent either with the sum of the drainage areas or the entire
project area.
b. On the drainage area map exhibit, please confirm the information presented for DA F. The pervious and
impervious area numbers are transposed from the other application documents. For instance, the other
application documents list a built -upon area of 14,683 sf but this exhibit lists the pervious area as being
14,683 sf.
2. 15A NCAC 02H.1001(1) and (5), .1002(23) and (26), 1042(1)(b) of the 2017 rules: This project is proposing to
both increase the amount of built -upon area directed to Basin E in Drainage Area F and increase the size of Basin
E. Both actions are considered a major modification under the 2017, subjecting both the increased BUA and the
stormwater control measure (SCM) design to the 2017 requirements and minimum design criteria (MDC). Since
the design storm remains the same for this drainage area at 1.5 inches, the increase in BUA is not a substantial
change. However, the SCM design is not that easy. Please either demonstrate that the project meets one of the
prior authorizations found in .1001(5) OR that the basin (either as constructed or as proposed) will meet the
minimum design criteria (MDC) found in .1050 and .1051 (this will require supplement-EZ to be used).
Since these are relatively minor, I was hoping that this e-mail would suffice instead of the formal letter requesting
additional information. However, if you'd rather the letter, please let me know and I will get one put together. Also,
feel free to let me know if you have any questions!
Thanks!

I have a couple questions on the supplement:
General MDC 42 - Is the infiltration system really located on or near contaminated soils? If so, please add to the
additional information comment at the bottom, that this was a previously permitted.system that is being expanded.
,eJty
Infiltraiton MDC 95 - Ponding depth is listed as being 24 inches (or 17 ft), but I thought the overflow was set at 16.35 ft?
(16.35 - 15.0 = 1.35 ft or 16.2 inches) Please confirm the ponding depth.
Thanks!

Repair Fire Lane Access Road, NH100
Marine Corps Base Camp Lejeune, NC
Contract Number N40085-16—B-0029
and
Design Additional Admin Space NH-100
Marine Corps Base Camp Lejeune, NC
Contract Number N40085-17-B-0112
Marine Corps Base Camp Lejeune, North Carolina is proposing to make improvements to the
existing fire access Lane which runs along the northern side of the Naval Hospital complex,
Building NH100 and make an administrative addition to the rear of the hospital. Specifically, it is
proposed that the existing 10 foot wide asphalt emergency access lane be widened to 12 foot
wide. Additionally, an adjacent existing gravel parking area will be paved. As part of the
proposed project, an existing concrete slab (prior basketball courts) will be replaced with a
more substantial pavement section, providing an access point for emergency vehicles. A 2,500
SF administrative addition will be made along the north side of NH-100.
The project occurs in two drainage areas as permitted under existing Stormwater Permit SW8
960329. Runoff occurs through Drainage Area "F" and the "Exemption Area" of the Naval
Hospital complex. There is no established boundary for the "Exempt" area. After consultation
with DEQ and the Base, an "Exempt" area drainage basin boundary was established to
encompass the project areas.
Runoff from Drainage Area "F" drains to Infiltration Basin "E". The existing BUA within this
drainage basin exceeds the permitted BUA limits. As a part of this project, the existing
infiltration basin will be enlarged slightly to provide the required storage volume from the BUA
that presently exists and that which will be modified by this project.
A portion of the Fire Lane project and all of the administrative office addition occurs in the
"Exempt" area. Runoff in the exempt area basin generally occurs through sheet -flow action to
vegetated areas surrounding the impermeable areas. This drainage pattern will be maintained
and will not be altered by the proposed construction. There will be a net reduction in the
"Exempt" Area of 5,730 SF. No collection systems or other means concentrating flow are
proposed by this project.
The project drains to Northeast Creek which is located in the White Oak River Basin. Northeast
Creek has a Surface Water Classification of SC, NSW, HQW and a Stream Index of 19 —16 —
(3.5).
No wetlands or stream buffer areas are located within the proposed projects limits of
disturbance.

Repair Fire Lane Access Road, NH100
Marine Corps Base Camp Lejeune, NC
Contract Number N40085-16—B-0029
Marine Corps Base Camp Lejeune, North Carolina is proposing to make improvements to the
existing fire access Lane which runs along the northern side of the Naval Hospital complex,
Building NH100. Specifically, it is proposed that the existing 10 foot wide asphalt emergency
access lane be widened to 12 foot wide. Additionally, an adjacent existing gravel parking area
will be paved. As part of the proposed project, an existing concrete slab (prior basketball
courts) will be replaced with a more substantial pavement section, providing an access point for
emergency vehicles.
As a part of the proposed construction, existing gravel surfaces located adjacent to the fire
access lane will be removed. The areas beyond the edges of the new pavement will be re -
vegetated in accordance with the project vegetation. The pavement widening will occur in the
areas of this existing gravel. As a result of the removal of the gravel edge surfacing, a net
reduction in impermeable surfaces will result from the completion of this project.
The project occurs in three drainage areas as permitted under existing Stormwater Permit SW8
960329. Runoff occurs through Drainage Area "B", Drainage Area "E" and the "Untreated Area"
of the Naval Hospital complex. A net reduction of impermeable surfaces will occur in each of
these drainage areas as a result of this project. The net reduction of impermeable surfaces for
each drainage area is proposed to be reserved for future development within each of these
drainage areas. The enclosed calculations document the demolished and new impermeable
surfaces by drainage area. The total net reduction of the BUA as a result of this project is
11,427 ft2. Runoff from Drainage Area "B" is treated by an existing stormwater retention pond
(Pond B). No modifications will be made to this existing stormwater pond as a result of this
project. Runoff from Drainage Area "E" drains to Infiltration Basin "F". No modifications will be
made to this existing infiltration basin as a result of the completion this project. Runoff in the
untreated basin area generally occurs through sheet -flow action to vegetated areas
surrounding the impermeable areas. This drainage pattern will be maintained and will not be
altered by the proposed construction. No collection systems or other means concentrating
flow are proposed by this project.
The project drains to Northeast Creek which is located in the White Oak River Basin. Northeast
Creek has a Surface Water Classification of SC, NSW, HQW and a Stream Index of 19-16 —
(3.5).
No wetlands or stream buffer areas are located within the proposed projects limits of
disturbance.

Joe,
As long as the pond will be constructed and put into operation before the temporary erosion control measures are
removed and sediment does not get into the wetlands or surface waters, you don't need to do anything for SW.

Joe,
Let the erosion control folks know if this is going to result in more area being disturbed than was originally authorized.
Also, I'm positive that you are going to need to submit a revised plan or a new plan. I will depend upon Carol or Rhonda
to discuss with you in detail.
.hristine will probably email you back when she gets a chance.
It is a busy day around here for everyone. There are several meetings today.

Medical Clinic, MCB Camp Lejeune — i(0O4)Z9
State Stormwater Permit #55�.OQBfr�(Base Entry Road - March 15, 2013)
Erosion Control Permit # ONSLO-2013-051, November 29, 2012
Janet,
The Medical Clinic project has a wet pond that will be built primarily where the main hospital entry road now exists. The
hospital entry road relocation by another contractor is way behind schedule. As a result, the Medical Clinic's pond cannot
be completely built at the front end of this project. The new road is roughed end by the roadway contractor. The pond will
be built before the Medical Clinic is completed. The Medical Clinic construction project is awarded and the Base does not
want to delay this contractor.
The pond will not be available for use as a sedimentation basin during the initial part of the clinic construction. As a result,
NAVFAC is asking us to design other temporary sediment basins in the interim - very quickly.
i would like to know what we can do from an express permitting standpoint to receive approval. I would also like to verify
that this is all good with our Stormwater Permit (Christine was the reviewer).

I would appreciate your thoughts.
Sincerely,
joe Avolis, PE
