Basically, you will need to submit a similar package (application, supplement(s), fee, plans, etc.) that you did for the original application. The new package will show the changes, including calculations for the BMP with the additional BUA. The only difference is we already have the soils report and O&M agreement, so those don't need to be re -submitted. GIN [ S p� Let me know if you have any questions once to get into it. z Robert D.

From: Lou Sadler[mailto:lsadler@thehayterfirm.com] Sent: Wednesday, May 05, 2010 10:04 AM To: Patterson, Robert Cc: gavin@baselinedevelopment.com Subject: FED -EX PERMIT (sw6100401) Robert, Fed -Ex has asked that we revised the paving at the Fed -Ex expansion project in Hoke County. It would involve adding some asphalt the loading dock area to accommodate small truck trailer parking. It is just under 1700sf of paving. How does this affect our storm water permit (sw6100401)? What will we need to do to make this change?

The purpose of this investigation was to provide a general characterization of the soils in the area proposed for a stormwater infiltration device, including a determination of the depth to evidence of a seasonal high water table and estimation of the permeability of the various soil layers. In -situ hydraulic conductivity testing was not conducted. All soil characteristics were described in accordance with the USDA Field Book for Describing and Sampling Soils. This report represents my professional opinion as a Licensed Soil Scientist. A hand -powered auger boring was advanced in the area proposed for the infiltration device (see Figure 1) to a depth of 100 inches below ground surface. Soil morphological characteristics indicating a seasonal high water table (SHWT) were observed at 90 inches below surface. Infiltration rates (permeability) range from 1.0 in/hr in the sandy clay loam layer between 62 and 90 inches to as high as 10.0 in/hr in the loamy sand textured soils at the surface. A soil profile description was collected at location #I and is attached to this report. I appreciate the opportunity to provide this service and trust that you will feel free to call on the again in the future. If you have any questions or need additional information, please contact me at your convenience.
