The following checklist outlines design requirements per the Stormwater Best Management Practices Manual
(N C Department of Environment, Health and Natural Resources, February 1999) and Administrative Code
Section 15 A NCAC 2H 1008
Initial in the space provided to indicate the following design requirements have been met and supporting
documentation is attached If the applicant has designated an agent in the Stormwater Management Permit
Application Form, the agent may initial below If a requirement has not been met, attach justification
Applicants Initials
System is located 50 feet from class SA waters and 30 feet from other surface waters
System is located at least 100 feet from water supply wells
of system is at least 2 feet above the seasonal high water table
d Bottom of the system is 3 feet above any bedrock or impervious sod horizon
Off-line system, runoff in excess of the design volume bypasses the system (bypass detail
provided)
System is designed to draw down the design storage volume to the proposed bottom
elevation under seasonal high water conditions within five days based upon infiltration
through -the bottom only (a hydrogeologic evaluation may be required)
g Sods have a minimum hydraulic conductivity of 0 52 inches per hour
item is not sited on or in fill material or DWQ approval has been obtained
Plans ensure that the installed system will meet design specifications (constructed or
restored) upon initial operation once the project is complete and the entire drainage area is
stabilized
j ystem is sized to take into account the runoff at the ultimate built -out potential from all
surfaces-draming to the system, including any off -site drainage
< System is located in a recorded drainage easement for the purposes of operation and
maintenance and has recorded access easements to the nearest public right-of-way
s em capture and infiltrates the runoff from the first 1 0 inch of rainfall (1 5 inch event
for areas draining to SA waters)
in Drainage area for the device is less than 5 acres
pretreatment device (filter strip, grassed swale, sediment trap, etc ) is provided
o Trench bottom is covered with a layer of clean sand to an average depth of 4 inches
p Sides of the infiltration trench are lined with geotext le fabric
q Rock used is free of fines (washed stone) and has a large void ratio
e to bottom area ratio is less than 4 1
Form SWU-107 Version 3 99 Page 2 of 4

s Observation well(s) are provided (case -by -case basis)
;etated filter is provided for overflow (50 feet for SA waters, 30 feet for other waters)
detail is shown on plans
enchmark for checking sediment accumulation is provided
IV. INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT
I After every runoff producing rainfall event and at least monthly inspect the bypass/overflow structure for
blockage and deterioration and the infiltration system for erosion, trash accumulation, grass cover, and general
condition
2 Repair eroded areas immediately, re -seed as necessary to maintain adequate vegetative cover, mow vegetated
cover to maintain a maximum height of six -inches, and remove trash as needed
3 Remove accumulated sediment annually or when depth is reduced to 75% of the original design depth Restore
depth to original design depth without over -excavating Over -excavating may cause the required water table
separation to be reduced and may compromise the ability of the system to perform as designed
4 The water level in any monitoring wells will be recorded after a 1 inch rainfall event and at least once a
month Chronic high water table elevations (within I foot of the bottom of the system for a period of three
months) shall be reported to DWQ immediately
5 If DWQ determines that the system is fading, the system will immediately be repaired or replaced to original
design specifications If the system cannot be repaired to perform its design function, other stormwater control
devices as allowed by NCAC 2H 1000 must be designed, approved and constructed
6 Remove accumulated sediment from the infiltration system annually or when depth in the unit is reduced to
75% of the original design depth The system shall be restored to the original design depth without over -
excavating Over excavating may cause the required water table separation to be reduced and may
compromise the ability of the system to perform as designed Removed sediment shall be disposed of in an
appropriate manner and shall not be handled in a manner that will adversely impact water quality (i e
stockpiling near a stormwater treatment device or stream, etc )
A benchmark shall be established in the infiltration system The benchmark will document the original
design depth so that accurate sediment accumulation readings can be taken The measuring device used to
determine the depth at the benchmark shall be such that it will give an accurate depth reading and not
readily penetrate into accumulated sediments
