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 June 3, 2014, and shall be subject to
the following specified conditions and Iimitations
I. DESIGN STANDARDS
1 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 on page 3 of this permit, the Project Data Sheet The stormwater control has
been designed to handle the runoff from 22,241 square feet of impervious area. This
system must be operated with a vegetated filter
3 The tract will be lunited to the amount of built -upon area indicated on page 3 of this
permit, and per approved plans
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 A permit modification must be
submitted and approved prior to the construction of additional built -upon area from
outside of the approved drainage area-

IV. UNDERGROUND INFILTRATION TRENCH OPERATION AND MAINTENANCE AGREEMENT
1 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 vegetative
cover to maintain a maximum height of six inches, and remove trash and blockages as needed to maintain
system performance
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 1 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 failing, 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
When the depth at the benchmark reads , the accumulated sediment shall be removed
from the system.
