and the approved stormwater management plans and specifications and other
supporting data as attached and on file with and approved by the Division of Water
Quality and considered a part of this permit
This permit shall be effective from the date of issuance until December 15, 2015, and
shall be subject to the following specified conditions and limitations
I DESIGN STANDARDS
This permit is effective only with respect to the nature and volume of stormwater
described in the application and other supporting data
2 This stormwater system has been approved for the management of stormwater
runoff as described in Section 16 on page 3 of this permit The stormwater
control has been designed to handle the runoff from 46,708 square feet of total
impervious area (Basin #1 — 44,154 sq ft, Basin #2 — 2,554 sq ft) Each basin
provides more than twice the required design volume and does not require a
bypass
3 The tract will be limited to the amount of built -upon area indicated on page 3 of
this permit, and per approved plans There is no allotment for future built -upon
area at the site
4 All stormwater collection and treatment systems must be located in either
dedicated common areas or recorded easements The final plats for the protect
will be recorded showing all such required easements, in accordance with the
approved plans
5 The runoff from all built -upon area within the permitted drainage area of this
project must be directed into the permitted stormwater control system

IV. INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT
I After every runoff producing rainfall event and at least monthly inspect the infiltration system for erosion,
trash accumulation, vegetative 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 After every runoff producing rainfall event and at least monthly inspect the bypass, inflow and overflow
structures for blockage and deterioration Remove any blockage and repair the structure to approved design
specifications
4 Remove accumulated sediment from the pretreatment system and infiltration basin annually or when depth
in the pretreatment 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 a stockpiling near a stormwater treatment device or stream, etc )
A benchmark shall be established in the pretreatment unit 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
When the design depth reads _NR feet in the pretreatment unit, the sediment shall be
removed from both the pretreatment unit and the infiitration basin
5 If the Division determines that the system is failing, the system will immediately be repaired to original
design specifications If the system cannot be repaired to perform its design function, other stoimwater
control devices as allowed by NCAC 2H 1000 must be designed, approved and constructed
I acknowledge and agree by my signature below that I am responsible for the performance of the five

NA f 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
BS g Drainage area for the device is less than 5 acres
BS h Soils have a minimum hydraulic conductivity of 0 52 inches per hour and soils report is
attached
BS i System captures and infiltrates the runoff from the first 10 inch of rainfall (1 5 inch event for
areas draining to SA waters ) Design volume and infiltration calculations attached
BS J System is sized to take into account the runoff at the ultimate built -out potential from all
surfaces draining to the system, including any off -site drainage Calculations attached
BS k All side slopes stabilized with vegetated cover are no steeper than 3 1 (H V)
NA 1 A pretreatment device such as a catch basin, grease trap, filter strip, grassed swale or
sediment trap is provided
BS in Bottom of the device is covered with a layer of clean sand to an average depth of 4 inches or
dense vegetative cover is provided
BS n Vegetated filter is provided for overflow and detail is shown on plans (Required minimum

Form S WU- E 03 Rev 3 99 Page 2 of 3
IV. INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT
1 After every runoff producing rainfall event and at least monthly inspect the infiltration system for erosion,
trash accumulation, vegetative 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 After every runoff producing rainfall event and at least monthly inspect the bypass, inflow and overflow
structures for blockage and deterioration Remove any blockage and repair the structure to approved design
specifications
4 Remove accumulated sediment from the pretreatment system and infiltration basin annually or when depth
in the pretreatment 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 pretreatment unit 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
When the design depth reads N 1 A feet in the pretreatment unit, the sediment shall be
removed from both the pretreatment unit and the infiltration basin.
5 If the Division determines that the system is failing, the system will immediately be repaired 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

FOR THE
construction, operation and maintenance of two infiltration basins in compliance with
the provisions of 15A NCAC 2H 1000 (hereafter referred to as the "stormwater rules')
and the approved stormwater management plans and specifications and other
supporting data as attached and on file with and approved by the Division of Water
Quality and considered a part of this permit
This permit shall be effective from the date of issuance until December 15, 2015, and
shall be subject to the following specified conditions and limitations
I DESIGN STANDARDS
This permit is effective only with respect to the nature and volume of stormwater
described in the application and other supporting data
2 This stormwater system has been approved for the management of stormwater
runoff as described in Section 16 on page 3 of this permit The stormwater
control has been designed to handle the runoff from 46,708 square feet of total
impervious area (Basin #1 — 44,154 sq ft, Basin #2 — 2,554 sq ft) Each basin
provides more than twice the required design volume and does not require a
bypass
3 The tract will be limited to the amount of built -upon area indicated on page 3 of
this permit, and per approved plans There is no allotment for future butlt-upon
area at the site
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
5 The runoff from all built -upon area within the permitted drainage area of this
project must be directed into the permitted stormwater control system
