High Density Commercial Wet Pond Project
Hertford County
The Washington Regional Office received a complete Stormwater Management Permit
Application for Structural Coatings Hertford on April 26, 2011. 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 2008-211 and Title 15A NCAC 2H.1000. We are
forwarding Permit No. SW7110411 dated May 6, 2011, for the construction of the subject
project.
This permit shall be effective from the date of issuance until May 6, 2021, 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,

To Whom It May Concern:
EXPRESS
APR 2 6 2011
The Structural Coatings Hertford site is located at the southeast corner of the
intersection of NC Hwy 461 (River Rd.) and Farmers Chemical Rd in Hertford County.
The overall acreage of the site is 41.8 acres. The proposed site consists of access drives,
gravel storage area for metal products and beams, and manufacturing building.
11-11
Total impervious area will be approximately 15.17 acres or 36.3% BUA. Runoff
from the site will be conveyed using combination of vegetated swales, sheet flow and
pipe conveyance system before discharging into one of three BMP's. The BMP's consist
of two proposed stormwater wetlands and one stormwater detention pond. The
stormwater detention pond is designed to treat 1.5" runoff at 90%TSS reduction before
being discharged to wetlands.
No impact of wetlands is planned for this development.
Plan Changes: To avoid conflict with crossing and obtaining permission to cross several
easements (mainly railroad and gas), the main access drive was relocated to the eastern
side of the property. A bypass Swale system is also proposed to allow offsite runoff to
pass through the property without treatment.
If you have any questions or concerns, please do not hesitate to contact this office.
Sincerely,
Jonathan L. Meade
Environmental Specialist

G 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.

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:
— The drainage area of the grassed swale will be carefully managed to reduce the
sediment load to the grassed swale.
— After the first-time fertilization to establish the grass in the Swale, fertilizer will
not be applied to the grassed swale.
The grassed swale will be inspected once a quarter. 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.

STORMWATER MANAGEMENT PERMIT APPLICATION FORM
LOW DENSITY SUPPLEMENT
This form may be photocopied for use as an original
A low density project is one that meets the appropriate criteria for built upon area and transports stormwater
runoff primarily through vegetated conveyances. Low density projects should not have a discrete stormwater
collection system as defined by 15A NCAC 214 .1002(18). Low density requirements and density factors can
be found in Session Law 2008-21 I, 15A NCAC 21-1 .1000, Session Law 2006-246, and the DWQ BMP Manual.
Curb and gutter systems are allowed provided they meet the requirements in 15A NCAC 214 .1008(g).

Refer to DWQ's forms and applications website for specific language that must be recorded in the deed
restrictions for all subdivided projects. (http://h2o.enr.state.nc.us/su/bmp_forms.htm)
Complete the following calculation in the space provided below where:
• SA Site Area - the total project area above Mean High Water.

• RA Road Area - the total impervious surface occupied by roadways.
• OA Other Area - the total area of impervious surfaces such as clubhouses, tennis courts, sidewalks, etc.
• No. of Lots - the total number of lots in the subdivision.
• BUA per Lot - the computed allowable built upon area for each lot including driveways and impervious
surfaces located between the front lot line and the edge of pavement.
• Total allowable lot BUA - the computed allowable built upon area for all lots combined.
• Total BUA from lot listing - the sum of built upon area allocated for each lot on the list of non -uniform lots.

V. SWALE SYSTEM MAINTENANCE REQUIREMENTS
I. Mowing will be accomplished as needed according to the season. Grass height will not exceed six inches
at any time; and grass will not be mowed too close to the ground or "scalped".
2. Swales will be inspected monthly or after every runoff producing rainfall event for sediment build-up,
erosion, and trash accumulation.
3. Accumulated sediment and trash will be removed as necessary. Swales will be reseeded or sodded
following sediment removal.
4. Eroded areas of the swales will be repaired and reseeded. Swales will be revegetated as needed and in a
timely manner based on the monthly inspections. Side slopes must be maintained at the permitted slope.
Catch basins, curb cuts, velocity reduction devices, and piping will be inspected monthly or after every
significant runoff producing rainfall event. Trash and debris will be cleared away from grates, curb cuts,
velocity reduction devices and piping.
6. Swales will not be altered, piped, or filled in without approval from NCDENR Division of Water Quality.
I acknowledge and agree by my signature below that 1 am responsible for the performance of the six
maintenance procedures listed above. I agree to notify DWQ of any problems with the system or prior to any
changes to the system or responsible party.
