In order to meet the stormwater management plan requirements associated with General Certification 3705, a stormwater management plan, dated February 27, 2008, 2008, was received by the DWQ on February 29, 2008. The DWQ has determined that your stormwater management plan was incomplete as discussed below. Additional Information. Requested: 1. The DWQ does not recommend the use of three separate stormwater wetlands in series due to the risk of embankment failure between the systems. If possible, please combine the three stormwater wetlands into a single, properly designed stormwater wetland. This ,may involve reconfiguring the wetland so that the stormwater does not undergo such a significant elevation change as it flows through the wetland. 2. Please provide a soils report that verifies that the level of the seasonal low water table is at 2940.0 find. If the water table is truly at that level, wetland number three will need to be redesigned because the embankment elevation at the outlet of this wetland is only at approximately 2937.75 find. 3. The proposed orifice diameter of eight inches is oversized and will result in a drawdown rate of much less than two days. Please resize the orifice for a two to five day drawdown rate. 401 OversighVExpress Review Permitting Unit 1650 Mail Service Center, Raleigh, North Carolina 27699-1650 2321 Crabtree Boulevard, Suite 250, Raleigh, North Carolina 27604 Phone: 919-733-1786 /FAX 919-733-6893 / Internet: htt~NhZo.enr.state.nc.us;ncwetlands NoOe Carolina ~atura!!r~ An Equal Opportunity/Affirmative Action Employer - 50% Recycled/10% Post Consumer Paper 08-0398 Peddler's Square April 17, 2008 Page 2 of 2: 4.
