Alan,
BIMS said this hasn't been issued yet - so here are my comments regarding stormwater.
Please let me know if you have questions.

DWQ considers the first phase of this project, construction of the access road, to
be high density. Per the requirements of GC 3705, this phase must comply with
Stormwater Management Plan (SMP) Requirements for Applicants Other Than
the North Carolina Department of Transportation, available at:
htip://h2o.enr.state.nc.us/ncwetlands/documents/SMPReguirementsforApplicants
othcrthanNCDOT.pdf. Please include an SMP that removes a minimum of 85
percent TSS from the stormwater generated by this project. For each proposed
BMP, please provide a completed BMP Supplement Form, with all the required
items. The BMP Supplement Forms are available at the following web site:
ham://h2o.enr.state.nc.us/su/bmp fornis.htm.
2. For the remainder of the project, please provide a conceptual stormwater
management plan for the project that includes the following:
a. A depiction of the drainage areas on the site.
b. An estimation of the percentage imperviousness associated with each of
the drainage areas.
c. A calculation of the water quality volume associated with each drainage
area.
d. A depiction of a proposed BMP (state the type of BMP you plan to use) on
the site plan that is correctly sized based on the water quality volume.
