RE: Review Comments
(December 17, 1998)

We have modified our drawing and/or calculations in accordance with your comments as follows:
1) The basin was proportioned such that the pre-bay is 20% of the total volume.
2) The notch angle was revised such that it will provide for a 2.5 day drawdown of the 1"
runoff,
3) The application was modified.
4) A note has been added.
5) The v-notch has been revised.
6) The calculations, plans and the supplement have been revised.
7) A map is included.

Subject: ACKNOWLEDGEMENT OF RECEIPT AND
REQUEST FOR ADDITIONAL INFORMATION
Stormwater Project No. SW8 980729
Dosher Memorial Hospital
Brunswick County
Dear Mr. Burton:
The Wilmington Regional Office received the previously requested information for the Stormwater
Management Permit Application for Dosher Memorial Hospital on November 30, 1998. 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. The supplement form still lists the forebay volume as 777 cubic feet, well below the required
20% of the total pond volume. From the calculations, it appears that you base the calculation
on the volume stored above the permanent pool, 3,884 cubic feet, when it should be based on
the total volume in the pond from the bottom of the pond to the permanent pool, 76,460 cubic
feet.
2. Please feel free to revise the supplement form as needed in order to convey that the orifice is
a V-notch weir. Please specify the notch angle. See comment#5 on the following page.
3. Please revise Section III, #6 of the application to reflect the new impervious area of 1.05 acres
draining to the pond.
4. I am unable to locate the note concerning wetlands. Please delineate all wetlands on site, or
note on the plans that none exist, tell me where I can find the note.
5. The orifice must be sized to pass the volume stored between the permanent pool and the
design storage pool in 2-5 days. It appears that you are basing the calculation on the minimum
required 1" volume. Please revise, see comment#6 on the following page.

Mr. Burton

Stormwater Project No. SW8 980729
6. You have used the rectangular weir equation to determine the flow through a triangular weir.
This is not correct. The equation to determine the flow over a V-notch weir is Q= C ir tan
(6/2), where C is .58, (for V-notch weirs, C varies only slightly with notch angle and head),
H is taken as the average head, and 0 is the notch angle. The average flowrate through a 60°
weir, with an average head of .105' (.21/2), is .00512 cfs. Using the calculated provided
volume in the pond of 4,016 cubic feet, the drawdown time will be 9 days, which is greater
than the required maximum of 5 days. Using the triangular weir formula, please work
backwards to find the notch angle that will provide the desired flowrate. Please calculate the
notch angle for both the 2 day and 5 day flowrates, and specify an angle between. My
calculation indicates the angle to be between 93° and 137°. Please revise the supplement sheet
and detail sheet.
7. Please provide a location map of the sampling point used to determine the salinity. Please
show the site and the sampling point on the map.
Please note that this request for additional information is in response to a preliminary review. The
requested information should be received by this Office prior to January 17, 1999, or the application will
be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including
the application fee. The Division is allowed 90 days from the receipt of a completed application to issue the
permit.
If you have any questions concerning this matter please feel free to call me at [phone].
Sincerely,
oiefrp.;20a_d

Subject: ACKNOWLEDGEMENT OF RECEIPT AND
REQUEST FOR ADDITIONAL INFORMATION
Stormwater Project No. SW8 980729
Dosher Memorial Hospital-Long Term Care Addition
Brunswick County
Dear Mr. Burton:
The Wilmington Regional Office received a Stormwater Management Permit Application for Dosher
Memorial Hospital on July 22, 1998. 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 Operation and Maintenance Plan was not signed. Please have it signed by the applicant
and return it.
O\P` 2. Detention ponds are not permitted within 1/2 mile of SA class waters, which is what the
�/N ICWW is. It appears that this system drains to an existing stormdrain line in the street. Please
� // provide a map showing the exact discharge point of this piping. The Southport Restricted
Area, is Class C waters, which will determine if a pond will be acceptable for treatment. If
the stormdrain line empties into class C waters, no chlorides test is required. If the stormdrain
line empties into class SA waters, a chlorides test is required. A-water sample must be taken
at a point in the receiving stream that is outside of a 1/2 mile arc drawn from the proposed
5( pond discharge point, after three days without rain.
{ up / 3. You have sufficient surface area in the pond to meet the surface area requirements for 90%
al° TSS, thus eliminating the need for a vegetated filter. If a pond is acceptable, you may revise
the calculations and use the 90% TSS table. Filters are just one more maintenance item, and
a difficult one, that can be eliminated.
3. The forebay sizing is based on 20% of the total volume in the pond from the bottom to the
permanent pool, not 20% of the surface area. Please recalculate for compliance.
4. Delineate all wetlands on site, or note on the plans that none exist.

5. The forebay's volume above the permanent pool is included in the total volume stored in the
pond, for the purposes of determining the depth of storage in the pond, and for sizing the
orifice.
IL 6. The flowrate through the specified weir is too small, resulting in a pond that does not
,►/ drawdown within 5 days, as required by regulation. The orifice must be sized for the total
volume provided between the permanent pool and the storage pool, not just the first 1". Please
, .42e Qu(1, submit revised calculations, and provide 2 copies of the plan sheet with the revised orifice
/yr�y 01 9 detail. Additionally, a rectangular weir is not recommended for use under low head
G, r� \ conditions, where accurate flowrates are needed. A V-notch weir is recommended. If you
y) y a, ( wish to continue with the rectangular weir, please provide information on how you arrived
O at 2.97 as the coefficient of discharge. My literature says that for sharp-crested weirs, C=
{,.-';� 3.27 + .4(H/P), where H is the head above the crest elevation, (I use the average head), and
P is the distance from the bottom of the channel to the crest. Using H=0.1, and P=6,
C=3.2767. Using H=0.2, the result is C=3.28. The minimum C value would be 3.27.
Additionally, due to the two end contractions, the length of the weir is effectively reduced.
The actual flowrate over a 0.072' weir with 2 end contractions is equivalent to the flow over
a 0.053' long weir with no end contractions. Please revise.
U`N 7. If you do not revise the pond calculations to 90% TSS, please provide a detail of the vegetated
filter on the plans.The BMP guidance document does not contain one specific for a pond, so
I enclose a detail for your use. Please add specific elevations for inverts and the flow
spreader.
V8. Please relocate the 6:1, 10' wide vegetated shelf under the permanent pool. The shelf is
intended to be submerged in shallow water and planted with wetland species.
9. Please add the dimensions of each side of the figure created by the permanent pool to the
plans, including the forebay.
2 10. The demolition plan shows a large amount of existing impervious areas to be removed. Since
.0..' , what is being put back exceeds the existing amount, you must demonstrate that the new
e L Pr�'• flowrate is less than or equal to the existing flowrate for that area. The drainage plan shows
0
��i a new piped system that will catch runoff from the replaced parking areas and continue to
`NAR Q drain it into the existingsystem, bypassing thepond. There is no credit
��,� Y � YP g given for those
�� replaced surfaces to continue to drain off the property without treatment.

✓11. FYI-The River basin for this project is the Cape Fear, not the Intracoastal Waterway. The
Waterway is the receiving stream. I have elected to make the appropriate changes to the
application.
12. From scaling the contours as shown on the plans, the permanent pool surface area is closer
to 17,500 square feet than the 19,166 square feet reported in the calculations. Please delineate
and label both the permanent pool and storage pool contours.Make sure that the area
delineated matches up with what is reported in the calculations. The permanent pool
dimensions to be added to the plans will be used to construct the pond, so they need to be
accurate. From the plans provided, there is a 12' distance from the bottom contour (assumed
to be the unlabelled contour shown at the pond's bottom) to elevation 17.5, but if the pond
depth is 6', and the slope is 3:1, then the horizontal distance from the bottom to contour 17.25
is 18'. The distance to 17.5 should be even greater, but it scales only 12'.
13. Please confirm that .86 acres is the total built-upon area to the pond. The supplement lists .35
acres, but the calculations use .86. The supplement and application should list the total built-
upon area (both onsite and offisite or existing).
Please note that this request for additional information is in response to a preliminary review. The
requested information should be received by this Office prior to November 21, 1998, or the application will
be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including
the application fee.
If you have any questions concerning this matter please feel free to call me at [phone].
Sincerely,

Another good one!
We still need to work toward some policy on redevelopment. In the
interim I think we have been going with the idea that the rules say
either you don't increase the built-upon or you provide equal or
better stormwater control. These people will obviuosly have to do the
second option (equal or better). The absolute minimum here would be
to treat the new built-upon only, but I think we need to try and get
them to treat as much of the area as possible!
We should also be checking these redevelopment cases to assure that
the projects were not previously covered by a stormwater permit or
certification. If they were covered previously then they don't get
any breaks, the project is subject.

NOTICE OF RECEIPT OF EROSION & SEDIMENTATION CONTROL PLAN
J. A. Dosher Memorial Hospital
Mr. Edgar Haywood, III, Administrator
9.24 N. Howe Street
Southport NC 28461
Dear Mr. Haywood, III:
This office has received a soil erosion and sedimentation control plan for the project listed below which
was submitted as required by the North Carolina Sedimentation Pollution Control Act (NCGS 113A-57).
Please be advised that this Act requires that all persons disturbing an area of one or more acres of land
must obtain approval of a soil erosion control plan prior to the commencement of said land disturbing activity
(NCGS 113A-54(d)(4)). The act further states that this plan must be filed a minimum of 30 days prior to the
activity and the approving authority must approve or disapprove the submitted plan within 30 days of receipt.
Failure of the approving authority to approve or disapprove the submitted plan within the 30 day period will
be deemed approval of the plan. Commencement or continuation of a land-disturbing activity under the
jurisdiction of this Act prior to the approval of an erosion and sediment control plan is a violation of the Act.
This land disturbing activity described in this plan is also subject to the Environmental Management
Commission's review of their regulations to implement stormwater controls in coastal counties (15 NCAC 2H
Section .1000). Contact the Water Quality Supervisor of the Division of Environmental Management to ensure
this activity is in conformance with their rules.
If you have questions, please do not hesitate to contact this office. Your cooperation in this matter
is appreciated and we look forward to working with you on this project.
