REQUEST FOR MORE INFORMATION: STORMWATER MANAGEMENT PLAN
Dear Mr. Morris:
On July 16, 2007, the Division of Water Quality (DWQ) issued a 401 Water Quality Certification to
impact to impact 3001inear feet of unnamed tributary to Long Creek to construct the transportation center
described in your application received by the DWQ on May 29, 2007. In order to meet Condition 6 of the
401 Certification for this project, a stormwater management plan was submitted to the DWQ on August 1,
2007. On August 27, 2007, the DWQ sent you a Stormwater Duplicity of Effort Notice. Since that time,
your consultant, John R. McAdams Company, Inc., has demonstrated that this project does not fall under
this policy and that the DWQ is the appropriate stormwater reviewing authority for this project.
The DWQ has reviewed the stormwater management plan for this project and determined that your
stormwater management plan was incomplete as discussed below.
Additional Information Requested:
The plan details indicate that the stormwater BMP is a stormwater wetland; however, a wet
detention basin supplement form was submitted in the stormwater management plan. Please
submit a stormwater wetland supplement form if that is the B1VIP that you are intending to use on
this site. The current version of the stormwater wetland supplement form can be accessed at the
following web site: htt~/1h2o enr.state.nc.us/sta/bmp folms.htm. In your resubmittal, please
provide both worksheets of the supplement form (Design Summary and Required Items
Checklist) and provide all of the items listed in the Required Items Checklist.
2. Please provide a properly designed forebay that will capture the sediment prior to the stormwater
entering the constructed wetland. Plants should not be specified in the forebay in order to
maximize sediment storage and facilitate clean out.
3. Please submit a signed and notarized inspection and maintenance form for a stormwater wetland.
The form that has been submitted pertains to a wet detention basin.
