Mike,
Attached is the revised Supplemental calculation sheet showing the volume provided. I also looked into the energy
dissipater for the outfall and the New York DOT Method used by NCDENR Land Quality for a 12" pipe at 9.67 fps calls for
Zone 2 apron material which is classified as light stone (Class B) that is approximately 3' long by 3' wide and a minimum
thickness of 18". The plans call for the pipe to outfall into the forebay and the detail shows the forebay to consist of
Class A rip rap 25' x8' x12" thick. I think this is sufficient to dissipate the flow since it is not just a small 3'x3' area.
I also have rotated the cell to show the 53' dimension parallel to the contours so that any excess water would sheet flow
over this edge and continue to sheet flow into the wooded area downstream of the cell. A 10' wide vegetative filter has
been added to the downstream side of the cell to stabilize the area and prevent erosion.
I have also attached a revised plan sheet showing the cell revisions.
Let me know if you have an questions or need any other information.
Thanks,

Mike,
Below are the answers to your questions. We have included the revised permit and a revised sheet C5.0.
The 3.7 acres includes the temporary drive and temporary sediment basin which will be removed and are
downstream of the project drainage area. Also this area would lower the percent impervious and the SWMP design
would be less conservative. The actual area of the project not including the temporary drive and basin is 3.08 acres.
The permit and calculations have been updated to reflect this value.
The permit has been updated to reflect the correct stream classification.
The calculations on the permit had been done specifically for the sub drainage area that is to be treated to account for
the addition in impervious area. These calculations have been revised and now reflect the entire project area. The basin
calculations reflect those only of the sub area to be treated that will discharge into the basin.
Please let me know if you have any other questions.
Thanks,
Tre Dugal, P.E.

Subject: SCC new classroom
Tre,
Got the application for the state stormwater permit for the new classroom at SCC. I'm assuming this is the Logan Hall
project. I have a couple of minor issues with the application.
1) application shows erosion control plan for 3.7 acres of disturbed area, but lists project area as 1.32 acres
2) the receiving stream is listed as Nicks Creek with classification of WS-III, this should be Mill Creek with classification of
WS-III;HQW;@ (stream index 18-23-11-(1)) or WS-III,B;HQW:@ (stream index 18-23-11-(2)) depending on which part of
Mill Creek the area would drain to.
I need an explanation of the difference between disturbed area and project area and a revised page 3 of 6 of the
application with the correct receiving stream name, classification and stream index. This can be e-mailed to me to save
time since the revision is not on a signature page.

Thanks,
Mike

IV. PROJECT INFORMATION
1. In the space provided below, briefly summarize how the stormwater runoff will be treated.
The stormwater runoff from the net increase of impervious area added due to the construction of the new
classroom building and new parking on an existing narking lot will be treated in a bioretention cell with a
f or bay for pretreatment
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 PUDApproval 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 I I — Post Construction
3. Storinwater runoff from this project drains to the
4. Total Property Area: 3.08 acres
River basin.
5. Total Coastal Wetlands Ana: 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':
3.08 acres
Total project area shall be calculated to exclude the fnlloraingg the nornud Vol of imppounded structures, the area
between the: hanks of streams and rivers, the area below the Norinai fl i,lt Water (Nt t W) Iiiie or Mean High Water
(MHW) line, and coastal wetlands landward froin the NHW (or M40) 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 ['reject Area) X 100 = 80 %
9. I -low many drainage areas does the project have?1 (For high density, count 1 for each proposed engineered
stornwater BMP. For low density and other projects, use 1 for the whole property areas)
10. Complete the following information for each drai age area identified in Project Information item 9. 1f 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.

Tre,
There is another item for revision on the application. The drainage area table and impervious surface area table shows a
total proposed impervious area of 45,738sf, however when adding up the different types of BUA in the table I get a total
of 45,561sf. This would also change the %impervious area slightly. I'll need this revision in addition to the ones I e-
mailed to you yesterday. Please provide these revisions by 10/13/10 to avoid having the application returned.

Dear Mr. Gough:
Dee Freeman
Secretary
Our office has received a copy of the Financial Responsibility/Ownership Form (FR/O) from the Division
of Land Resources, Land Quality Section for the Sandhills Community College Logan Hall project to be located
in Moore County. Based on project location information provided on the FR/O, we have determined that the
project may be subject to a State Stormwater Management Permit for development activities within one mile of
and draining to High Quality Waters (HOW).
Please be advised that construction of any built -upon areas prior to issuance of a State
Stormwater Management Permit will be considered a violation of the NC Administrative Codes and could
result in the assessment of civil penalties of up to $25,000 per day, per violation. The State Stormwater
Management Permit is in addition to the NPDES Stormwater General Permit (NCG010000) received for
construction activities. For more information and to obtain the application and applicable supplement forms,
