Subject: Stormwater Project No 8W f 6803G3 reviTton—l*—'' -
Seven Falls Village Area — Phase 1 and 2
Henderson County, North Carolina
The Division of Water Quality received a complete Stormwater Management Permit
Application for Seven Falls Village Area — Phase 2, on August 11, 2008. Staff review of the plans
and specifications has determined that the project, as proposed, will comply with the Stormwater
Regulations set forth in Session Law 2006-246, We are forwarding the revised Permit No,
SW 1080303 dated April 19, 2008 as revised August 12, 2008, for the construction of the subject
project.
This permit shall be effective from the date of issuance until April 18, 2018, 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) 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 27611-7447. Unless such demands
are made this permit shall be final and binding.
This project will be kept on file at the Asheville Regional Office. If you have any
questions, or need additional information concerning this matter, please contact the Asheville
Regional Office at 828-296-4500.

Subject: Request for Additional Information
Stormwater Project No. SW 1080303
Seven Falls Golf and River Club Phase 2
Henderson County
Dear Mr. Vinson:
The Division of Water Quality Central Office received a Stormwater Management Permit
Application for the subject project on July 2, 2008. A preliminary review of that information has
determined that the application is not complete. The following information is needed to continue
the stormwater review:
1. Please provide a vegetation plan for the vegetated shelf and the slopes of the wet
pond.
2. The average depth indicated in the calculations assumes a four -foot depth to
determine the 1.43 SA/DA ratio. The supplement form indicates an average depth of
3.06 or a 1.73 SA/DA ratio. Please correct the supplement form and/or the
calculation sheets.
3. Please correct the application form to reflect two drainage areas. One drainage area
for the BMP and a separate drainage area for the Basin bypass. The drainage area for
the BMP should include the total area draining to the BMP including the area of the
BMP.
4. Please provide a copy of the 401/404 Permit.
Please note that this request for additional information is in response to a preliminary review.
The requested information should be received by this Office prior to September 1, 2008, or the
application will be returned as incomplete. The return of a project will necessitate resubmittal of
all required items, including the application fee. If you need additional time to submit the
information, please mail or fax your request for a time extension to the Division at the address
and fax number at the bottom of this letter. The'request must indicate the date by which you
expect to submit the required information. The Division is allowed 90 days from the receipt of
a completed application to issue the permit.
The construction of any impervious surfaces, other than a construction entrance under an
approved Sedimentation Erosion Control Plan, is a violation ofNCGS 143-215.1 and is subject to
enforcement action pursuant to NCGS 143-215.6A. One

Operation and Maintenance Agreement
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 maintenance procedures:
— Immediately after the filter strip is established, any newly planted vegetation
will be watered twice weekly if needed until the plants become established
(commonly six weeks).
Once a year, the filter strip will be reseeded to maintain a dense growth of
vegetation
Stable groundcover will be maintained in the drainage area to reduce the
sediment load to the vegetation.
Two to three times a year, grass filter strips will be mowed and the clippings
harvested to promote the growth of thick vegetation with optimum pollutant
removal efficiency. Turf grass should not be cut shorter than 3 to 5 inches and
may be allowed to grow as tall as 12 inches depending on aesthetic requirements
(NIPC, 1993). Forested filter strips do not require this type of maintenance.
— Once a year, the soil will be aerated if necessary.
Once a year, soil pH will be tested and lime will be added if necessary.
After the filter strip is established, it will be inspected quarterly and within 24 hours
after every storm event greater than 1.0 inch (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.

Wet Detention Basin Operation and Maintenance Agreement
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.
The wet detention basin system is defined as the wet detention basin,
pretreatment including forebays and the vegetated filter if one is provided.
This system (check one):
® does ❑ does not incorporate a vegetated filter at the outlet.
This system (check one):
❑ does ® does not incorporate pretreatment other than a forebay.
Important maintenance procedures:
Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
— If the basin must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain should be minimized to the
maximum extent practical.
— Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected 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 should be kept in a known set
location and must be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.
