Dear Mr. Johnson:
Natural Resources
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 Physical Plant project on
,tune 9, 2010. 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. 'therefore, we are
forwarding herewith Stormwater Management Permit SW6100501 dated .tune 15, 2010, for the
construction, operation, and maintenance of stormwater treatment facilities associated with the subject
project.
This permit shall be effective from the date of issuance until June 14, 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

3. The tract will be limited to the amount of built -upon area indicated in Section 1.7 of this permit
and per approved plans.
4. All stormwater collection and treatment systems must be located in either dedicated common
areas or recorded easements. The final plats for the project will be recorded showing all such
required easements, in accordance with the approved plans.

operational for its intended use prior to the construction of any built -upon surface.
2. During construction, erosion shall be kept to a minimum and any eroded areas of the system will
be repaired immediately.
3. The permittee shall at all times provide the operation and maintenance necessary to assure the
permitted stormwater system functions at optimum efficiency. The approved Operation and
Maintenance Plan most be followed in its entirety and maintenance must occur at the scheduled

b. Sediment removal.
C. Mowing and revegetation of slopes and the vegetated filter.
d. Immediate repair of eroded areas.
e. Maintenance of all slopes in accordance with approved plans and specifications.
f. Debris removal and unclogging of bypass structure, infiltration media, flow spreader,

Total project area shall be calculated to exclude the following the normal pool of impounded structures, the area
between the banks of streams and rivers, the area below the Normal High Water (NHW) line or Mean High Water
(MHW) line, and coastal wetlands landward from the NHW (or MHIO line. The resultant pproject area is used to

Infiltration Basin Operation and Maintenance Agreement

log in a known set location. Any deficient BMP elements noted in the inspection will bg V�
corrected, repaired or replaced immediately. These deficiencies can affect the µ�
of structures, safety of the public, and the removal efficiency
Important maintenance procedures:
— The drainage area will be carefully managed to reduce the sediment load to the'D •
infiltration basin.
— Immediately after the infiltration basin is established, the vegetation will be
watered twice weekly if needed until the plants become established (conmionly
six weeks).
— No portion of the infiltration basin will be fertilized after the initial fertilization
that is required to establish the vegetation.
— The vegetation in and around the basin will be maintained at a height of
approximately six inches.
After the infiltration basin is established, it will be inspected once a quarter 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.
