Re: DWQ Project #09-1345, Ver. 2
Granville Medical Center
Granville County
Dear Mr. McMillan,
In response to your letter dated July 12, 2010, we offer the following responses:
1. The second version of this project includes omissions from the Required Items
Checklist for the sand filter. If the re-submittal fails to include all required items at the
correct scales, then the project will be returned.
Response: After meeting with Annette Lucas of your office to review the checklist and
her requirements regarding the sand filter, we sincerely believe we have addressed all
concerns such that you can now approve our application.
2. EXHB-02 displays the following problems:
a. The scale is stated to be at 1" = 40', but the actual drawing is at significantly
smaller scale. Please provide the drawing at a 1 " = 40' scale.
Response: We have added a sheet to our plan set that displays the information
at a more legible scale.
b. The boundaries of the drainage area are not shown clearly.
Response: The boundaries of the drainage areas are now darker and can now
be more clearly seen. A linetype has been added to the legend of sheet EXHB-
02.
c. The proposed boundaries of the drainage easement are not shown at all.
Response: The boundaries of the drainage easement can now be more clearly
seen on revised sheet EXHB-02.
d. The new and existing portions of the project are not clearly denoted.
Response: The new and existing portions of the project can now be more clearly
denoted on revised sheet EXHB-02.
3. EXHB-03 displays the following problems:
a. The scale is stated to be at 1" = 50', but the actual drawing is at a
significantly smaller scale. Please provide the drawing at a 1" = 20' scale as
required in the Required Items Checklist.
Response: We have added another 24"x36" sheet to our plan set that displays
the information at a more legible 1" =20' scale.
b. The dimensions of the proposed sand filter cannot be evaluated because of
the problems with the scale. Please do ensure that the size of the sand filter
shown on the scaled plans matches the area given in the Design Summary.
Response: We have added another 24"x36" sheet to our plan set that displays
the sand filter at a more legible scale. The drawing agrees with size called for on
the design summary.
c. You must include the system dimensions, the flow splitting device, the
boundaries of the drainage easement, the outlet device, the baffle,
underdrain and clean-out locations and any other pertinent design information
on this plan.
Response: We have added another sheet to our plan set that displays the sand
filter at a more legible scale. This drawing shows the requested dimensions.
4. EXHB-04 displays the following problems:
a. Per the Required Items Checklist, this drawing must be to scale. The
horizontal scale must be 1" =20' or larger and the vertical scale may be larger
for clarity.
Response: After meeting and talking to the DWQ, the detail provided is larger
and more clearly denoted with appropriate dimensions.
b. Please show the level of the temporary water storage elevation.
Response: The temporary water elevation is shown.
5. Please address the follow design problems that were brought up during Version 1 of
the project:
a. The area of the sand filter shown on the plans does not match the area
claimed on the Sand Filter Supplement Form. The DWQ will not approve a
sand filter with such unusual geometry.
Response: We have revised the geometry of the sand filter as agreed to at our
meeting with Ms. Lucas.
b. The sand filter must be equipped with a flow splitting device. Plan details and
supporting calculations for this device must be provided.
Response: A flow splitter device and calculations were previously submitted as
was discovered at our meeting. However, an additional cross section has been
provided for the flow splitter for clarity of the design. The 15" outlet discharging
to the sedimentation chamber has been sized to receive the volume from the 1"
storm before the stormwater inside the chamber overtops the weir and bypasses
the sand filter via a 15" outlet to the stream.
c. The storm drainage system is not depicted in a clear enough manner to verify
the size of the drainage area.
Response: By adding a larger sheet providing the storm drainage area at a larger
scale and darkening the lines, its size is readily verifiable.
6. A scour hole may not be installed upslope of an area with a 24% slope. Please
discharge the overflow from the sand filter directly to the stream. Please provide details
of how this discharge point will be designed.
Response: We are now proposing a direct discharge into the stream as is shown
on this resubmittal. The allowable impacts from this discharge are shown on the
sheet and the PCN form has been updated.
7. The soils report does not provide an estimate of the level of the SHWT. This
information must be provided.
Response: The best estimate of the SHWT by a SEPI environmental scientist is
included with this submittal.
8. The Operation and Maintenance Agreement has been omitted.
Response: The O & M Agreement was previously submitted as was discovered
at our meeting with Ms. Lucas.
9. Please provide cross section details showing the provisions for aquatic life passage.
Response: We are now proposing installing a junction box on the end of the
existing culvert and dropping the invert of the new pipe 12" to provide the
requested aquatic life passage. A cross section detail is shown on our
resubmittal on EXHB-04.
10. Please clarify the amount of stream impacts. The stream impacts table S1 and
footnote indicate an impact length of 85 linear feet, however, the total for stream impacts
in the table is 80 linear feet, and the cover letter states 60 linear feet in several places.
Please state which amount is correct.
Response: The impact length is 85 linear feet which includes 60 linear feet of
pipe extension and 25 linear feet of riprap outlet protection. The PCN application
table and cover letter have been revised to indicate this.
If you should have any questions or additional comments, please do not hesitate to let
us know.

Re: Granville Medical Center, Section 404/401 NWP 39 and Tar-Pamlico River Buffer
Authorization; NCDWQ Project 09-1345
Dear Mr. McMillan:
SEPI Engineering & Construction, Inc (SEPI), on behalf of the Granville Health System,
submitting this Section 401 Nationwide Permit 39 application. Concurrent with this
submission for the Section 401 Water Quality Certification (WWQC), SEPI also requests a Tar-
Pamlico River buffer authorization for the proposed project. The project is located off of US
15 in Oxford, North Carolina. To accommodate expansion of an existing hospital to meet
the needs of the surrounding community served by the facility, Granville Health System is
requesting this Section 401 Nationwide Permit 39 and Tar-Pamlico buffer authorization.
Project Description
The proposed project involves the expansion of the existing hospital, including an
Emergency Department and Surgery Department addition and a new Boiler/ Generator
Plant. The original hospital was constructed in 1939 with additions in 1962, 1974, 1985
and 1998. This proposed project involves the hospital expanding its emergency
department. Expansion of these hospital functions is needed to provide more effective care
for the surrounding community currently served by the facility.
The growth of the hospital footprint requires the relocation of existing access roads and
parking areas further east to the back portion of the property. The existing main hospital
access road currently terminates at the Emergency Department. With the expansion of the
Emergency Department, the access road needs to be moved to allow access to the new
public entrance at the rear of the facility. There is no alternative location to build the
access road. It served before as the main entrance to the emergency room and is planned to
also serve as the main entrance for both ambulance and patient drop off. The other service
entry poses a safety issue as incoming traffic will cross rail road tracks and would be forced
to stop if a train was on the tracks.
The site of the Granville Medical Center encompasses +/-15.03 acres. The existing
impervious area is approximately 58% of the total parcel. With the addition of the new
?SEPI
EPage 2
parking areas and the building expansion, and the demolition of some parking the final
impervious percentage, the new total impervious is approximately 65% of the total parcel.
The drainage area of the site is approximately 9.75 acres. Based this drainage area, the
percentages for the existing and final impervious areas are approximately 56% and 67%
respectively. The sand filter is sized to treat only the new parking areas that account for
the increase in the impervious area.
Runoff from the new proposed northern parking lot will be directed to the sand filter. Due
to the steep slopes, the discharge from the sand filter will discharge into a preformed
riprap scour hole instead of a level spreader. A flow splitter is designed to control the
amount of flow going into sedimentation basin before entering the sand filter.
Project Site Investigation
The site for the proposed expansion has been reviewed for wetlands, streams and buffers.
For the proposed expansion site, the Granville County soil map depicts one drainage type
on the site, and the US Geologic Survey map also notes a drainage type. SEPI reviewed the
area associated with the proposed expansion, and we determined that the drainage is a
jurisdictional stream and is subject to the Tar-Pamlico buffer requirements. There are no
wetlands present in this area for the proposed expansion.
Mr. Martin Richmond of the NCDWQ conducted a site on October 8, 2009. Mr. Richmond
has provided a concurrence letter, and it has been attached to this buffer application.
Project Impacts to Waters of the United States
The layout of the proposed expansion cannot avoid impacts to the jurisdictional stream and
its associated riparian buffer. To access the back portion of the hospital tract, the road
improvements must be made. The existing pipe will be extended to accommodate the
hospital expansion and the access road.
Stream impacts total 85 feet, less than 0.01 acre of surface water. Impacts to the stream
were minimized by implementing a design slope of 2:1.
At this time, no compensatory mitigation for the stream impact is proposed.
Project Impacts to Tar-Pamlico Buffers
The layout of the proposed expansion cannot avoid impacts to the riparian buffer. To
access the back portion of the hospital tract, the road improvements must be made. This
side slope also minimized impacts to the Tar-Pamlico buffer. Table 1 summarizes impacts
to the Tar-Pamlico buffer.
Table 1. Project Buffer Im acts from the Pro osed Hospital Expansion
Buffer Zone 1 6,871 sq uare feet
Buffer Zone 2 4,428 sq uare feet
S SEPI
Page 3
Based on a review of the "Table of Uses" for the Tar-Pamlico buffer rules, we believe that
the proposed action fits into the category of "Road Impacts other than crossing of streams
and other surface waters subject to this rule".
All impacts are included in the PCN. However, there were not sufficient rows to convey the
impacts in the PCN so we have included the following table.

Impact number action Permanent or
Temporary
Zone 1
Zone 2
Road impacts Permanent 6,411 4,263
Temporary 717 350
Sewer line Permanent 460 165
Temporary 1,892 1,681
Sand Filter Discharge Permanent 654 241
Total Buffer Impacts 10,134 6,700
Granville Health System proposes to pay into the Riparian Buffer Fund to compensate for
impact to the Neuse buffers. Table 2 summarizes the impacts to the buffers and the
required payment.

On behalf of the Granville Health Systems, SEPI has coordinated the payment into the
Riparian Buffer Fund with the Ecosystem Enhancement Program. The EEP has agreed to
provide the required buffer compensation, and a copy of the acceptance letter is attached
to this application for a buffer authorization.

Closing
SEPI asks that the USACE issue a Section 404 NWP 39 for the proposed project to impact 85
feet of stream (<0.01 acre of surface water impact). Additionally, SEPI asks that the NC
Division of Water Quality issue its corresponding 401 WQC and a Tar-Pamlico buffer
authorization for the proposed action. Granville Health System proposes to pay into the
EEP in-lieu fee program for the buffer impacts; no compensatory mitigation for stream
impacts is proposed at this time.

RE: Seasonal High Water Table - Granville Medical Center Stormwater BMP Pond
Oxford, NC; DWQ Project # 09-1345.
Dear Mr. McMillan:
This letter is in response to the Granville Medical Center Section 401 Application Comment #7
regarding the Seasonal High Water Table (SHWT) provided to Mr. Gerry Leighton (Granville Health
System) on July 12, 2010. SEPI reviewed data from the Natural Resources Conservation Service
(NRCS) Web Soil Survey for Granville County, NC (MRCS 2010) as well as the Official Soil Series
Descriptions on the NRCS Website (MRCS 2010) to obtain an estimate of the SHWT of the area in
question. Upon review of the data it was noted that the SHWT is at a depth of 72 to 78 inches below
ground surface (BGS). The existing ground elevation in the area of the proposed sand filter is 450 ft.
Based on the SHWT data from the NRCS, the SHWT would reside at 443.5 to 444 ft at the area in
question.
If you have any additional questions regarding these findings, please feel free to call or email me.
Sincerely,
P ilip Beach

Description
"Water table" refers to a saturated zone in the soil. It occurs during specified
months. Estimates of the upper limit are based mainly on observations of the water
table at selected sites and on evidence of a saturated zone, namely grayish colors
(redoximorphic features) in the soil. A saturated zone that lasts for less than a month
is not considered a water table.
This attribute is actually recorded as three separate values in the database. A low
value and a high value indicate the range of this attribute for the soil component. A
"representative" value indicates the expected value of this attribute for the
component. For this soil property, only the representative value is used.

loam that weathered from saprolite; massive; friable; common fine flakes of mica; very strongly acid.
TYPE LOCATION: Union County, North Carolina; about 1.8 miles west of Wesley Chapel on North
Carolina Highway 84, about 2.2 miles north on Secondary Road 1338 to its intersection with Secondary
Road 1358, about 250 feet northwest of the intersection, in a cultivated field; USGS Matthews
topographic quadrangle; lat. 35 degrees 03 minutes 18 seconds N. and long. 80 degrees 43 minutes 25
seconds W..
RANGE IN CHARACTERISTICS: The Bt horizon is at least 24 to 50 inches thick and extends to 40
inches or more. Depth to bedrock ranges from 6 to 10 feet or more. The soil is very strongly acid or
strongly acid throughout, unless limed. Limed soils typically are moderately acid or slightly acid in the
upper part. Content of coarse fragments ranges from 0 to 35 percent by volume in the A and E horizons
and 0 to 10 percent by volume in the Bt horizon. Fragments are dominantly gravel in size. Most pedons
have few to common flakes of mica in the A and Bt horizons and few to many flakes of mica in the BC
and C horizons.
The A or Ap horizon has hue of 5YR to 2.5Y, value of 3 to 6, and chroma of 2 to 6. The A horizon is
sandy loam, fine sandy loam, coarse sandy loam, loamy sand, loamy coarse sand, in the fine earth
fraction. Eroded phases are sandy clay loam or clay loam in the fine earth fraction.
The E horizon has hue of 5YR to 2.5Y, value of 4 to 6, and chroma of 4 to 6. It is sandy loam, fine
sandy loam, coarse sandy loam, loamy sand, or loamy coarse sand in the fine earth fraction.
The BA or BE horizon has hue of 5YR to l OYR, value of 5 or 6, and chroma of 3 to 8. It is sandy clay
loam or sandy loam.
The Bt horizon contains 35 to 60 percent clay and extends to depths of 30 to 60 inches. It has hue of
5YR to 2.5Y, value of 4 to 6, and chroma of 4 to 8. Pedons of 5YR hue have evident patterns of
mottling in a subhorizon of the Bt horizon. Mottles in shades of red, yellow, and brown range from few
to many throughout most pedons. The Bt horizon is sandy clay, clay loam, or clay with thin layers of
sandy clay loam and contains less than 30 percent silt.
The BC horizon has hue of 5YR to 2.5Y, value of the 4 to 7 and chroma of 4 to 8, or is mottled in these
colors. BC horizons that have hue of 5YR have evident patterns of mottling. The BC horizon is clay
loam, sandy clay loam, or sandy clay.
The C horizon is similar in color to the BC horizon or is multicolored. It is saprolite weathered from
felsic high-grade metamorphic or igneous rock that typically has a loamy texture.
COMPETING SERIES: These are the Bethlehem, Cecil, Georgeville, Herndon, Madison, Nanfo_rd,

are the Cataula, Chestatee, Cullen, Durham, Grover, Hard Labor, Helena, Hulett, Lloyd, Mayod_an, Rion,
and Vance series. Bethlehem soils have soft bedrock at depths of 20 to 40 inches and sola less than 40
inches thick. Cataula soils have a perched water table at 2 to 4 feet. Cecil soils have dominant hue of
5YR or redder; where hue is 5YR, evident patterns of mottling are absent in the Bt and BC horizon.
Chestatee soils contain more than 15 percent, by volume, coarse fragments throughout. Cullen soils have
more clay in the Bt horizon. Helena, Mayodan and Vance soils have mixed mineralogy, and in addition
Helena soils have a perched water table at 1.5 to 2.5 feet and Mayodan soils formed in Triassic age
sediments. Durham, Grover and Rion soils are fine-loamy. Georgeville, Herndon, Nanford, and Tarrus
soils formed in Carolina slate and contain more than 30 percent silt. Hard Labor soils have a perched
water table at 2.5 to 5 feet. Hulett, Madison, Pacolet and Wedowee soils have thinner Bt horizons, and,
in addition Hulett and Madison soils contain more mica. Nankin soils formed from marine sedinments.
Lloyd soils have at least one subhorizon in the Bt horizon that has moist value of 3. Saw soils have hard
bedrock at depths of 20 to 40 inches.
GEOGRAPHIC SETTING: Appling soils are on broad nearly level to gently sloping ridges and on
sloping to moderately steep sides of ridges between intermittent and permanent streams in the southern
Piedmont. Slopes are mostly from 2 to 10 percent but range from 0 to 15 percent. Appling soils formed
in residuum weathered from felsic igneous and high-grade metamorphic rock. Near the type location, the
mean annual precipitation is 45 inches and the mean annual air temperature is 60 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: In addition to the competing Cecil, Durham, Hard
Labor, Helena, Pacolet, Rion, Vance and Wedowee series, these are Colfax, Louisburg, and Worsham
series. Colfax soils are somewhat poorly drained to moderately well drained and have a fragipan.
Louisburg soils contain less than 18 percent clay in the Bt horizon. Worsham soils are poorly drained
and are around the heads of drains.
DRAINAGE AND PERMEABILITY: Well drained; medium to rapid runoff, moderate permeability.
USE AND VEGETATION: Most of the acreage is in cultivation or pasture and the remainder is in
forests of mixed hardwoods and pine. Common crops are corn, tobacco, soybeans, cotton, and small
grains.
DISTRIBUTION AND EXTENT: The Piedmont of Alabama, Georgia, North Carolina, South
Carolina, and Virginia. The series is of large extent.
MLRA OFFICE RESPONSIBLE: Raleigh, North Carolina
SERIES ESTABLISHED: Columbia County, Georgia; 1911.
REMARKS: The June 1988 revision recognized low activity clay properties of this soil as defined in
the Low Activity Clay Amendment to Soil Taxonomy, August, 1986 and changed the classification
from Typic Hapludults to Typic Kanhapludults. The December 2005 revision changed the type location
from a mesic region (Rockingham County, North Carolina) to a thermic region.
Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon - the zone from the surface of the soil to a depth of 12 inches (Ap, E, and BE horizons)
Kandic horizon - the zone between 12 and 48 inches has low activity clay in more than 50 percent of the
horizon (Bt horizon)
Argillic horizon - the zone between 12 and 48 inches (Bt horizon)
