Dear Mr. Fierle:
Project
The Stormwater Permitting Unit received a complete Stormwater Management Permit
Application for West Intermediate School on January 14, 2010; with additional information
received February 4th and 11 , 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 i 5A NCAC 2H.1000 and Session Law 2006-246. We are forwarding Permit No.
SW1100101, dated February 12, 2010, for the construction, operation and maintenance of the
subject project and the stormwater BMPs.
This permit shall be effective from the date of issuance until February 12, 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 inspection and maintenance of the stormwater management system will result in future
compliance problems.
The site is below the low density threshold for BUA, but is not permitted as such due to the
extent of the collection systems on the site. The site has existing BUA that does not require
stormwater treatment per the stormwater rules, except for those portions of the site that have
some existing BUA runoff directed to the BMPs in this permit. There are also two rainwater
harvesting systems.on the site. While they are providing additional stormwater treatment of
runoff, they are not receiving direct stormwater credit under this permit. The cistern in DA 1 is
being used in lieu of a vegetative filter strip after the wet pond.
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 til'is permit. This request must be in the form of a written petition, conforming to

Stormwater Project No. SWI100101
West Intermediate School
Buncombe County
Dear Mr. Day:
The Division of Water Quality Central Office received a Stormwater Management Permit Application for
the subject project on January 11, 2010. 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. The application forni (SWU-101), supplement forms, and calculations do not show consistent
values for DA and impervious area. Please make everything consistent for the DAs on WS 1.
2. Please provide a table on sheet WS 1 that lists the following BUA for each drainage area:
existing treated, existing not treated, proposed treated, and proposed not treated, Include the
area of the site not in one the delineated DAs. Also, for the site as a whole, list the BUA for
total existing (to remain and to be removed) and total proposed.
3. Please provide two copies of the site, grading, and landscape plans and details sheets.
4. The wetlands and streams need to be shown on the stormwater and grading plans. The required
30' setback for impervious area needs to be shown along streams.
5. Please provide planting plans and details for the pond and bioretention cells.-
b. As per 2 on the required items checklists, a plan view of each BMP needs to be provided at a
scale of l" = 30' or larger.
7. Permanent drainage easements need to be provided around each BMP.
S. The details and supplements show 4' of media depth for the bioretention cells, but the plans
show 2'. Please make these consistent.

9. The supplements show the cells will be grassed, but the detail shows mulch. If using grass, no
mulch is needed, and the type of sod to be used must be specified.
10. The soils report submitted does not provide. the information required for review of SHWT
elevations. Please provide a soils report that specifically states a SHWT elevation for each
BMP. This is not the same as whether or not ground water was present at the tirne of the
borings. It also appears that a boring was not performed for cell #7.
11. The table in the calculations showing contour areas and volumes should be continued down to
the bottom of the pond. Also, provide data at the temporary pool elevation.
12. The head used in the orifice drawdown calculations must use 1-1/3 as per the BMP Manual. H is
measured From the orifice elevation up to the next available outlet.
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 February 5, 2010, 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, fax, or email 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 40 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 of NCGS 143-215.1 and is subject to enforcement
action pursuant to NCGS 143-215.6A.
Please reference the State assigned project number SW1100101 on all correspondence. All original
documents must be returned or new originals must be provided. Copies are not acceptable. If you have
any questions concerning this matter please feel free to call me at [phone].

Inspection Summary:
Susan Wilson inspected the site on July 24, 2012. The plans were taken in the field to perform a proper review.
The site does not appear to be totally stabilized (although all BMPs are in place and impervious surface areas are in
place).
There are 6 grassed bioretention basins and 1 wet detention pond. All BMPS appeared to be constructed as designed.
The facility appears to have tried to get the grass to grow in the detention basins, but due to the hot/dry summer - they are
not completely vegetated. The engineer has not yet signed -off on the project.
[The assumptions made during the previous visual inspection (31212012) were incorrect - the site is as designed and the
drop inlets are constructed properly. With benefit of the plans, this inspector was able to determine the piping
configuration.]

Bioretention 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 13MP 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 (or1.5 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 ogre):
❑ 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.
