Colecn 11. Sullins Director
Division of Water Quality
Dear Mr. Marshburn:
The Wilmington Regional Office received a State Stormwater Management Permit Application
for TECOM (MCCSSS) Interim Facilities, MCB, CLNC on June 26, 2008. A preliminary review
of that information has determined that the application is not complete. The following
information is needed to continue the stormwater review:
1.) It appears that the forebay volume, permanent pool volume, average depth, and
associated calculations include the 1-foot sediment accumulation depth. The
depth of the permanent pool is considered to be difference between the
permanent pool elevation and the top elevation of the sediment storage and does
not include the minimum 1-foot sediment accumulation depth (refer to Figure 10-
2b and Section 10.3.4 of the 2007 BMP manual). Please revise the calculations
and supplement to consider just the permanent pool in the pond calculations as
well as the forebay volume calculations.
2.) The Bald Cypress Trees as indicated on D-5 of the plans should be planted .
outside of the vegetative shelf or slopes of the detention pond.
3.) Please remember that a change to one number may have a domino effect on
other numbers. Please check all plans, calculations and forms and make changes
as needed.
4.) Please submit a $500 fee for the additional review required for this application.
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 July 18, 2008, or the
application will be returned as incomplete. The return of a project ittal of
all required items, including the application fee.

14878 US Hwy 17 — Suite 5
Hampstead, NC 28443
RE: Camp Lejeune Infiltration Testing and Soil Characterization
Dear Jeff
Pursuant to your request, Spangler Environmental, Inc (SEI) performed a limited soil infiltration and soil
' characterization study at Camp Lejeune in Jacksonville, NC. SEI was requested to perform 5 tests on 3 different
locations. A representative of SEI mobilized to the sites and performed this work on February 13" and February
14", 2008. Methodology and results of this study are detailed in this report.
' Field Investigation Procedures
SEI performed testing at sites referred to by the client as Humvee Garages, Geiger Buildings and Devil Dog (see
' Exhibit A for locations). Testing was performed to determine hydraulic conductivity at the proposed elevation of
infiltration BMPs, determine seasonal high water table and identify soil characteristics. To perform these tests, SEI
utilized the following materials: 8" PVC pipe with an inner diameter of 7.75"(Infiltration Pipe) and measuring a
length of 30", measuring tape, sledgehammer, rounded tip shovel, 2.5" diameter soil auger and digital camera to
' photograph observations (Exhibit C).
Infiltration testing was performed by digging a test pit of 2 feet in depth with an appropriate width to provide optimal
' placement of the testing equipment (See Exhibit D for photos of methodology). Upon completion of this test pit, the
infiltration pipe was placed into the soil to a minimum depth of 6 inches using an 8-pound sledgehammer to reach the
desired depth. After placement of the infiltration pipe was complete, clean water was poured around the pipe to
ensure saturation of the adjacent soil to ensure accurate results of the infiltration testing. While saturation was
occurring, the soil auger was used to identify soil characteristics and locate the seasonal high water table (SHWT).
Soil was identified by color, texture, degree of saturation and depth of these characteristics. Upon saturation of the
surrounding soil, the infiltration pipe was filled with clean water to a fill line located on the inside of the infiltration
pipe. The duration of infiltration testing was one hour and Ile change in water level was measured in inches to
determine the infiltration rate. All subsurface depths in this report are listed as negative values measured from the
existing ground surface level.
Observations
Humvee Garages
Soil and Infiltration testing was performed on the "Humvee Garages." Testing was performed to the southeast of the
existing drivers training course. While digging the test pit, SEI identified that the existing soil is not a residual soil
and instead is a fill soil consisting of various soil textures and colors. For this report, SEI identified the dominant
soil structure that was present during investigation. See Table I in Exhibit B for a detail of soil characteristics. Soil
saturation was located at -51 inches below land surface and SEI identifies this point as the probable location of the
seasonal high water table. Infiltration testing at this site rendered an infiltration rate of .75 inchthour.

I
Geiger Buildings
' Soil and infiltration testing was performed in the location identified as "Geiger Buildings" on a site at the corner of A
Street and 6" Street. Soil identification showed a uniform material throughout the horizon. See Table 2 in Exhibit B
for a detail of soil characteristics. The seasonal high water table was located at 48 inches below land surface and
' was identified by the soil saturation and change in soil color at this depth. Infiltration testing on this site rendered an
infiltration rate of 20 inches/hour.
' Devil Dog— Administration Building
Soil and Infiltration testing was performed in the location identified as "Admin" on the Devil Dog site. Soil
identification was performed and SEI observed a well-strucmred, residual soil. See Table 3 in Exhibit B for a detail
of the soil characteristics. From our observations, SEI found that the seasonal high water table is likely located
between -51 inches and -54 inches below land surface, and is indicated by a saturated soil with grey mottles.
Infiltration testing on this site rendered an infiltration rate of 4.3 inches/hour.
' Devil Dog— Large Classroom
Soil and Infiltration testing was performed in the location identified as "Large Classroom" on the Devil Dog site.
Soil identification was performed and SEI observed a well -structured, residual soil. See Table 4 in Exhibit B for a
detail of the soil characteristics. SEI observed that the seasonal high water table is likely at 42 inches below land
' surface. Infiltration testing on this site rendered an infiltration rate of4.2 inches/hour.
Devil Dog —Thunder Dome
Soil and Infiltration testing was performed in the location identified as "Thunder Dome" on the Devil Dog site. Soil
identification was performed and SEI observed a well -structured residual soil. See Table 5 in Exhibit B for a detail
of the soil characteristics. SEI observed that the seasonal high water table is likely at 48 inches below land surface.
Infiltration testing on this site rendered an infiltration rate of3.7 inches/hour.
We appreciate serving Hobbs Upchurch and Associates on this project. Please feel free to contact us should there be
any questions or should any additional detail be required regarding soil and infiltration testing of these sites.
Sincerely,
Spangler Environmental, Inc.

All proposed infiltration areas and existing, active utility lines located within the proposed
basin/trench must be marked and flagged. If these areas are not flagged, the Soils Scientist
reserves the right to decline to do the investigation. If the poposed infiltration system will be
located in an area of existing pavement and there is no open area nearby, equipment capable of
breaking through the impervious layer must be provided. The soils investigation does not take
the place of a soils report prepared by an appropriate professional. The Soils Scientist will only
verify the soil conditions that are reported in the Soils Report, and make a determination as to
the suitability of the site to meet the infiltration design requirements under NCAC 2H.1000, and
assumes no liability should the system fail.
