Subject: State Stormwater Management Permit No. SW8 960329
Camp Lejeune Naval Hospital, Parking Lot Addition, and Medical Clinic
High Density Commercial Wet Detention Pond and Infiltration Project
Onslow County
Dear Mr. Paul:
Dee Freeman
Secretary
The Wilmington Regional Office received a complete modified Stormwater Management Permit
Application for the Camp Lejeune Naval Hospital, Parking Lot Additions, and Medical Center on
December 12, 2012. Staff review of the plans and specifications has determined that the
project, as proposed, will comply with the Stormwater Regulations set forth in Title 15A NCAC
21-1.1000 and Session Law 2008-211. We are forwarding Permit No. SW8 960329 dated
December 17, 2012 for the construction of the subject project.
On August 5, 2009, the Governor signed Session Law 2009-406. This law impacts any
development approval issued by the Division.of Water Quality under Article 21 of Chapter 143 of
the General Statutes, which is current and valid at any point between January 1, 2008, and
December 31, 2010. The law extends the effective period of any stormwater permit that is set to
expire during this time frame to three (3) years from its current expiration date. On August 2,
2010, the Governor signed Session Law 2010-177 which grants an extra year for a total of four
(4) years extension.
Accordingly, this permit, which was set to expire on February 20, 2018, shall be effective from
the date of issuance until February 20, 2022, which includes all available extensions, and shall
be subject to the conditions and limitations as specified therein. Please pay special attention to
the Operation and Maintenance requirements in this permit. Failure to establish an adequate
system for operation and maintenance of the stormwater management system will result in
future compliance problems.
The following modifications are included and covered by this permit:
1. The addition of one (1) wet detention pond (Pond J) designed to handle the runoff from
the proposed Medical Center.
2. Decreases the drainage area for Pond E from 108,222 square feet to 63,600 square feet
as the drainage area removed is now included in the drainage area for Pond J.
3. The previously approved layout and grading plans remain in effect and are incorporated
into the current approved plan set.
Please note that a portion of the drainage area and impervious area associated for Pond J 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. Therefore until the
permit SW8 090630 is modified to remove this portion of the project, this portion of the roadway
will be covered under both this permit, SW8 960329, and SW8 090630. The impervious areas
proposed within the limits of SW8 090630 will require either a plan revision to allocate a
portion of the future BUA for the proposed improvements or a modification to remove the
overlapping area from that permit. Please submit the revision or modification to SW8 090630
by January 11, 2012.

DIVISION OF WATER QUALITY
STATE STORMWATER MANAGEMENT PERMIT
HIGH DENSITY COMMERCIAL DEVELOPMENT
In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North
Carolina as amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
US Marine Corps Base, Camp Lejeune
Camp Lejeune Naval Hospital, Parking Lot Addition, and Medical Center
Building NH 100, Stone St, Camp Lejeune, Onslow County
FOR THE
construction, operation and maintenance of eight (8) wet detention ponds and one (1) infiltration
basin in compliance with the provisions of 15A NCAC 2H .1000 and Session Law 2008-211
(hereafter collectively referred to as the "stormwater rules') the approved stormwater
management plans and specifications and other supporting data as attached and on file with
and approved by the Division of Water Quality and considered a part of this permit.
This permit shall be effective from the date of issuance until February 20, 2022, and shall be
subject to the following specified conditions and limitations:
I. DESIGN STANDARDS
This permit is effective only with respect to the nature and volume of stormwater
described in the application and other supporting data.
This stormwater system has been approved for the management of stormwater runoff as
described in Sections 1.8 and 1.9 of this permit. The stormwater controls identified as
East Pond (also identified as Pond G), West Pond (also identified as Pond H), Pond A,
Pond B, Pond C, Pond D, Pond E, Basin F, and Pond J have been designed to handle
the runoff from 60,039 square feet (ft); 35,902 ftz; 68,668 ftZ; 183,793 ft ; 77,011 ftZ;
38,410 ft2; 23,668 ft2; 10,296 ft2, and 230,673 ftz of impervious area, respectively.
3. 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. Therefore until the
permit SW8 090630 is modified to remove this portion of the project, this portion of the
roadway will be covered under both this permit, SW8 960329, and SW8 090630. The
impervious areas proposed within the limits of SW8 090630 will require either a plan
revision to allocate a portion of the future BUA for the proposed improvements or a
modification to remove the overlapping area from that permit. Once the revision to SW8
090630 has been approved, a correction to this permit will be issued to acknowledge the
final actions related to this area.

4. 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.
5. Within drainage area I, an additional 27,450 square feet of untreated impervious area
was previously approved under the permit issued July 1996, and renewed on February
20, 2008.
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 1.8 and 1.9 of this permit, and per approved plans. Within drainage area
J, there is 10,000 ft2 of impervious area allocated for future development. 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.

Stormwater runoff will be treated by a wet detention pond sized for 90% TSS removal. Pretreatment will be
accomplished with parking island infiltration and bio swales. '
2. a. If claiming vested rights, identify the supporting documents provided and the date they were approved:
❑ Approval of a Site Specific Development Plan or PUD Approval Date:
❑ Valid Building Permit Issued Date:
❑ Other: Date:
b.If claiming vested rights, identify the regulation(s) the project has been designed in accordance with:
❑ Coastal SW -1995 ❑ Ph II - Post Construction
3. Stormwater runoff from this project drains to the
4. Total Property Area: 33.76 acres
River basin.
5. Total Coastal Wetlands Area: 0 acres
6. Total Surface Water Area: 0 acres
7. Total Property Area (4) -Total Coastal Wetlands Area (5) -Total Surface Water Area (6) = Total Project
Area*:33.76 acres
Total project area shall be calculated to exclude the folloeoing the normal ool of impounded structures, the area
between the banks of streams and rivers, the area below the Nornml High Water (NHW) line or Mean High Water
(MHW) line, and coastal wetlands landward froin the NHW (or MHW) line. The resultant }project area is used to
calculate overall percent built upon area (BUA). Non -coastal wetlands landward of the NHW (or MHW) line may
be included in the total project area.
8. Project percent of impervious area: (Total Impervious Area / Total Project Area) X 100 = 49.5 %
9. How many drainage areas does the project have?7 (For high density, count 1 for each proposed engineered
stormwater BMP. For low density and other projects, use 1 for the whole properhj area)
10. Complete the following information for each drainage area identified in Project Information item 9. If there
are more than four drainage areas in the project, attach an additional sheet with the information for each area
provided in the same format as below.

Infiltration Basin Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important maintenance procedures:
— The drainage area will be carefully managed to reduce the sediment load to the
infiltration basin.
— Immediately after the infiltration basin is established, the vegetation will be
watered twice weekly if needed until the plants become established (commonly
six weeks).
— No portion of the infiltration basin will be fertilized after the initial fertilization
that is required to establish the vegetation.
— The vegetation in and around the basin will be maintained at a height of
approximately six inches.
After the infiltration basin is established, it will be inspected once a quarter and within
24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal
County). Records of operation and maintenance will be kept in a known set location
and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

Stormwater Project No. SW8 960329
Naval Hospital and Parking Lot Addition and Medical Clinic
Onslow County
Dear Mr. Baker:
Dee Freeman
Secretary
The Wilmington Regional Office received a modified Express Stormwater Management
Permit Application for the Naval Hospital and Parking Lot Addition and Medical Clinic on
November 27, 2012. A preliminary review of that information has determined that the
application is not complete. The following information is needed to continue the
stormwater review:
The narrative indicates that the 2 inch storm is set to drawdown in 3 days
The state stormwater rules specifically note that the required storage
volume must draw down in two to five days. Please demonstrate that the
drawdown of the required 1.5 in design storm through the selected orifice
will occur in two to five days.
2. Please confirm the temporary pool elevation. Many of the application
documents indicate that the temporary pool elevation is 21.28 ft, however
the pond cross section on plan sheet C-104 indicates it is 20.18 ft. Please
ensure the information is presented consistently and accurately
throughout the application documents.
3. 9ue to the minor nature of these comments, the express additional
information fee has been waived.
4. Please keep in mind that changing one number may change other
numbers and require the calculations, supplements, and other supporting
documentation to be updated. Verify all numbers are correct to ensure
consistency in the application documents.
Please note that this request for additional information is in response to a preliminary
review. The requested information should be received in this Office prior to December
14, 2012, or the application will be returned as incomplete. The return of a project will
necessitate resubmittal of all required items, including the application fee.

letter. Please note that a second significant request for additional information may result
in the return of the project. If the project is returned, you will need to reschedule the
project through the Express coordinator for the next available review date, and resubmit
all of the required items, including the application fee.
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.
Please label all packages and cover letters as "Express" and reference the project
name and State assigned project number on all correspondence. If you have any

Stormwater Management Narrative, NAvgz
PrDD "10,0 AND PSU4 Medical Clinic Replarrm iM
Stone Street
MCB Camp Lejeune, NC
(Modification SW8 960329)
This project proposes the construction of a new medical clinic near the existing Naval
Hospital complex. The facility includes a new building and associated parking areas.
The project drainage area will be designated as drainage basin "]" on the existing Naval
Hospital permit # SW 960329. The existing drainage basin "E" on the overall drainage
area map is reduced in size where this project overlaps its development into that drainage
basin. For basin "E", the drainage area is reduced in size, the percent impervious area is
incieased and the impervious area remains the same. The pond in drainage basin "E" was ,
checked through calculations to still draw down satisfactorily.
The project will have a wet detention pond sized for 90% TSS removal for stormwater'ND
treatment. The basin is sized to treat the stormwater runoff associated with the 2.0 inch
storm. The project area is established as a total of 10.833 acres in size. The project built -
upon area is 48.9%. Eleven acres of the site will be disturbed by this project in order to
construct the site improvements including the wet pond.
The NCDENR required design storm is 1.5 inches due to the classification of the
receiving watercourse. The federal stormwater treatment requirement for this project as a
federal project disturbing over 5,000 square feet is 2.0 inches based on the 90°i percentile
rainfall event obtained from historical climatic data. The project is designed to detain the
2.0 inch rainfall even. Stormwater pretreatment by infiltration and filtration is
accomplished by a combination of parking lot islands and bio swales which are not a part
of the NCDENR requirements.
The soils on the site are classified as Baymeade by the Onslow County Soil Survey.
Baymeade is described as a fine sandy loam at the depths to be disturbed by this project.
The Baymeade soil will help to promote stormwater infiltration before the runoff reaches
the stormwater detention basin.
The depth to the seasonal high water table at the site was determined to be 30 inches
(elevation = 20.0 feet) by a soil scientist (FCS Ltd.). The depth to standing groundwater
was greater than 70 inches. The infiltration rate of the soils was determined to be 2.1,
5.5, 3.4 and 0.014 inches/hour at four separate locations. The wet detention basin
permanent pool level is set at an elevation of 19.5 feet. The draw for the 2.0
inch storm is set at three days.
ECE'VE

Bya.

The property is owned by the Federal Government. There have been no previous permits
issued for the work area. Thee is off -site and pervious area draining into the site which
is included in the watershed area boundary.
The sewer system for the property is a gravity collection system discharging to the base's
treatment plant. The sewer main will be relocated in order to construct the infiltration
basin. There are no known historic sites on the property.
The site drains to Northeast Creek, a tributary of the New River. Northeast Creek is
classified as SC;NSW,HQW, index #19-16-3.5. There are not any Coastal or 404
wetlands on the site. This project does not impact any wetlands. The wetlands were
delineated by .loseph C. Avolis, PE, Presidcnt Avolis Engineering, PA.
This project requires post development runoff rate control which is accomplished by the
wet detention pond to pre -development conditions (wooded) for the I -year, 24-hour
storm.
"fhe new drainage basin "J" will receive runofffrom the adjoining Base Entry Road low
density portion of that project. Since this medical clinic project is accepting that runoff,
no modification is being made to the actual Base Entry Road stormwater permit (SW8
090630).
This project also involves the demolition of an existing elementary school complex
approximately one mile away. That building was originally going to be remodeled as the
medical clinic. Due to various issues, that facility would not work. That demolition
work is being handled as a separate stormwater redevelopment submittal.

Dear Mr. Avolis:
ECS, Carolinas, LLP- (ECS) recently conducted infiltration, testing for the proposed
stormwater best, management practice (BMP) areas at the Medical Clinic Replacement
site on Camp Lejeune,!_Onslow County; North Carolina. This letter, with' attachments,
is thereport of our testing. .

Field Testing
I
On February 1, 2012! ECS conducted ;an . exploration of the ' subsurface soil and
groundwater conditions at three :requested, locations shown on the attached Test
Location Plan (Figured):_ The test areas were field located using a boring location plan
provided by Avolis Engineering,' PA. The. purpose of this „exploration was to obtain
subsurface" information of the in -place soils. for the proposed stormwater BMP"areas.
ECS, explored the'subsurface soil and groundwater conditions by advancing one hand
auger boring into the existing ground surface atthe requested boring locations., ECS'
visually classified the s subsurface soils and obtainetl representative samples of each
soil type encountered I 'ECS also recorded the groundwater level and the seasonal
high water table{SHWT)'bbservedat the time of the,:hand auger borings -The attached
Infiltiation'Testing Form,provldes a summary ofthe subsurface conditions encountered
atthe hand auger boring;location`s.
i
The:' groundwater level and,the SHWT were; estimated at the boring locations below the
existing grade elevatioi..A summary of'
the findingsare as follows:

Stormwater Management Narrative
P8144 Medical Clinic Replacement
Stone Street
MCB Camp Lejeune, NC
(Modification SW8 960329)
This project proposes the construction of a new medical clinic near the existing Naval
Hospital complex. The facility includes a new building and associated parking areas.
The project drainage area will be designated as drainage basin "J" on the existing Naval
Hospital permit # SW 960329. The existing drainage basin "E" on the overall drainage
area map is reduced in size where this project overlaps its development into that drainage
basin. For basin "E", the drainage area is reduced in size, the percent impervious area is
increased and the impervious area remains the same. The pond in drainage basin "E" was
checked through calculations to still draw down satisfactorily.
The project will have a wet detention pond sized for 90% TSS removal for stormwater
treatment. The basin is sized to treat the stormwater runoff associated with the 2.0 inch
storm. The project area is established as a total of 10.833 acres ih size. The project built -
upon area is 48.9%. Eleven acres of the site will be disturbed by this project in order to
construct the site improvements including the wet pond.
The NCDENR required design storm is 1.5 inches due to the classification of the
receiving watercourse. The federal stormwater treatment requirement for this project as a
federal project disturbing over 5,000 square feet is 2.0 inches based on the 90`h percentile
rainfall event obtained from historical climatic data. The projeef;is designed to detain the
2.0 inch rainfall event. Stormwater pretreatment by infiltration and filtration is
accomplished by a combination of parking lot islands and bio swales which are not a part
of the NCDENR requirements.
The soils on the site are classified as Baymeade by the Onslow County Soil Survey.
Baymeade is described as a fine sandy loam at the depths to be disturbed by this project.
The Baymeade soil will help to promote stormwater infiltration before the runoff reaches
the stormwater detention basin.
The depth to the seasonal high water table at the site was determined to be 30 inches
(elevation = 20.0 feet) by a soil scientist (ECS Ltd.). The depth to standing groundwater
was greater than 70 inches. The infiltration rate of the soils was determined to be 2.1,
5.5, 3.4 and 0.014 inches/hour at four separate locations. The wet detention basin
permanent pool level is set at .an elevation of 19.5 feet. The draw down period for the 2.0
inch storm is set at three days.
VED
nine 1 J 2012

The property is owned by the Federal Government. There have been no previous permits
issued for the work area. These is off -site and pervious area draihing into the site which
is included in the watershed area boundary.
i
The sewer system for the property is a gravity collection system discharging to the base's
treatment plant. The sewer main will be relocated in order to construct the infiltration
basin. There are no known historic sites on the property.
The site drains to Northeast Creek, a tributary of the New River.' Northeast Creek is
classified as SC;NSW,HQW, index #19-16-3.5. There are not any Coastal or 404
wetlands on the site. This project does not impact any wetlands. The wetlands were
delineated by Joseph C. Avolis, PE, President Avolis Engineering, PA.
This project requires post development runoff rate control which is accomplished by the
wet detention pond to pre -development conditions (wooded) for the 1-year, 24-hour
storm.
The new drainage basin "J" will receive runoff from the adjoining Base Entry Road low
density portion of that project. Since this medical clinic project is accepting that runoff,
no modification is being made to the actual Base Entry Road stormwater permit (S W 8
090630).
This project also involves the demolition of an existing elementary school complex
approximately one mile away. That building was originally going to be remodeled as the
medical clinic. Due to various issues, that facility would not work. That demolition
work is being handled as a separate stormwater redevelopment submittal.

YES you can, as long as you are not proposing to add piping to pick it up. If you just keep the
"existing" approved drainage (swales?), then no modification to the BER permit is needed.

Subject: Naval Medical Clinic; Base Entry Road
Linda:
I have gotten most everything worked out for a submittal on the new medical clinic at the Naval Hospital
complex. The one thing left that I have to address in our documents is the roadway in front of the new
building, The roadway is a side road associated with the new base entry road irealignment and is a low
density area that is treated by grass swales. Our project intercepts runoff from the roadway that we
cannot avoid and directs it into our wet pond. The drawing plans that I had gotten out of the stormwater
file did not have a drainage area for the roadway shown. Some other note appeared to designate the
roadway drainage boundary as 200' wide.
I will be treating the roadway water runoff. Can I just accept this runoff without modifying the entry road
permit which would of course be easy. Thank you for your help and thoughts..

No, I am the one who was mistaken. I thought this clinic was within the
Hospital's stormwater permit but after looking at the drawings it is in a
separate drainage area. It would probably be best to permit this as a
separate permit.

We are replacing a clinic that is about one mile away. That clinic is being
demolished with nothing else going back except for grass at that location.
The work is part of the same contract. That is why the erosion control
area is larger. For that additional offsite area, we are planning on
submitting an exemption or a redevelopment permit, reserving the BUA that is
already there. The clinic being replaced was previously an elementary
school in the Berkely Manor housing area.

was greater than 70 inches. The infiltration rate of the soils was determined to be 2.1,
5.5, 3.4 and 0.014 inches/hour at four separate locations. The wet detention basin
m'J5 r
permanent pool level is set at an elevation of 19.5 feet. The draw down period for the 2.0
inch storm is set at three days.
The property is owned by the Federal Government. There have been no previous permits
issued for the work area. There is off -site and pervious area draining into the site which
is included in the watershed area boundary.

The sewer system for the property is a gravity collection system discharging to the base's
treatment plant. The sewer main will be relocated in order to construct the infiltration
basin. There are no known historic sites on the property.
The site drains to Northeast Creek, a tributary of the New River. Northeast Creek is
classified as SC;NSW,HQW, index #19-16-3.5. There are not any Coastal or 404
wetlands on the site. This project does not impact any wetlands. The wetlands were
delineated by Joseph C. Avolis, PE, President Avolis Engineering, PA.
This project requires post development runoff rate control which is accomplished by the
wet detention pond to pre -development conditions (wooded) for the I -year, 24-hour
storm.
