Dear Mr. Gough:
Dee Freeman
Secretary
The Fayetteville Regional Office of the Division of Water Quality received a complete Stormwater
Management Permit Application for the Sandhills Community College New General Classroom
Building project on September 2. 2010. Staff review of the plans and specifications associated with
additional information received on September 16, 2010 and September 27, 2010 has determined that the
project, as proposed, will comply with the Stormwater Regulations set forth in Title 15A NCAC 2H
.1000. Therefore, we are forwarding herewith Stormwater Management Permit SW6100901 dated
October 4, 2010, for the construction of the subject project.
This permit shall be effective from the date of issuance until October 3, 2020 and shall be subject to 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 thirty (30) calendar days following receipt
of this permit. This request must be in the form of a written petition, conforming to Chapter 150B of the
North Carolina General Statutes, and filed with the Office of Administrative Hearings, P.O. Drawer
27447, Raleigh, NC 2761 1-7447. Unless such demands are made, this permit shall be final and binding.

I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important operation and maintenance procedures:
— Immediately after the bioretention cell is established, the plants will be watered
twice weekly if needed until the plants become established (commonly six
weeks).
— Snow, mulch or any other material will NEVER be piled on the surface of the
bioretention cell.
— Heavy equipment will NEVER be driven over the bioretention cell.
— Special care will be taken to prevent sediment from entering the bioretention cell.
— Once a year, a soil test of the soil media will be conducted.
After the bioretention cell is established, I will inspect it once a month and within 24
hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal
County). Records of operation and maintenance will be kept in a known set location
and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.
