Dear Mr. Best:
The Wilmington Regional Office received a complete Stormwater Management Permit Application for
the modification of GE — Tooling Repair Center on December 3, 2007. Staff review of the plans and
specifications has determined that the project, as proposed, will comply with the Stormwater
Regulations set forth in.Title 15A NCAC 2H.1000 and Session Law 2006-246. We are forwarding
Permit No. SW8 071003 dated December 6, 2007, for the construction of the subject project.

the conditions and limitations as specified therein. Please pay special attention to the Operation and
Maintenance requirements in this permit. Failure to establish an adequate system for operation and
maintenance of the stormwater management system will result in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to
request an adjudicatory hearing upon written request within sixty (60) days following receipt of this
permit. This request must be in the form of a written petition, conforming to Chapter 150E of the North

WILMINGTON, NC
December 3, 2007
The address of the site is 3901 Castle Hayne Road, Wilmington, NC. The General Electric
site encompasses approximately 1,670 acres. This project involves constructing a + 1.6
acre building along with two large parking lots. The project area for this project totals 21.2
acres The pond designed for this project has been designed for future impervious area that
is planned to be built in the future. The wet pond will be designed. to meet New Hanover
County's and NCDWQ's stormwater requirements. Calculations are provided for sizing
the culverts for 25-year storm and limiting the runoff from the detention pond to pre
development flow rates for the 1 yr, 2 yr, 10 yr and 25 yr events.
The season high water table at the pond location is 18 inches below the surface. The
elevation at the location checked was elevation 29. Thus the seasonal high water table is
at elevation 27.50. The proposed normal pool elevation is at elevation 25.00. The pond
will be lined with a liner made of existing soils and bentonite that will meet a permeability
of 1 x 10-6 cm/sect. The depth of the liner will be confirmed before construction, once all
the soils testing has been completed. A 12 inch layer of existing on site material will be
placed on top of the liner during construction.
The soils on site are On (Onslow Type B), Be (Baymeade Fine Sand, Type A/D), Mu
(Murville Fine Sand, Type A), Wr (Wrightsboro Fine Loam, Type C), Ke (Kenansville Fine
Sand, Type A.D) and Pn (Pantego Loam, Type B/D. (For soils with the soils group "A/D" or
