This hermit shall be effective from the date of issuance until August 25, 2010, 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, conforming to Chapter 150B of the North Carolina General Statutes, and filed

GDC a. System is located 50 feet from class SA waters and 30 feet from other surface waters.
COC b. System is located at least 100 feet from water supply wells.
Or— c. Bottom of system is at least 2 feet above the seasonal high water table.
C12� d. Bottom of system is 3 feet above any bedrock or impervious soil horizon.
Cam' e. System is not sited on or in fill material or DWQ approval has been obtained
C(, 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.
Cot_
g. Drainage area for the device is less than 5 acres.
h.. Soils have a minimum hydraulic conductivity of 0.52 inches per hour and soils report is
attached.
6f%G i. System captures and infiltrates the runoff from the first 1.0 inch of rainfall (1.5 inch event
for areas draining to SA waters). Design volume and infiltration calculations attached.
CjrX_ 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.
CjcX k. All side slopes stabilized with vegetated cover are no steeper than 3:1 (H:V).
COL 1. A pretreatment device such as a catch basin, grease trap, filter strip, grassed swale or
sediment trap is provided.
m. 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.

- , IV.;'- INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT
. After every runoff producing rainfall event and at least monthly, inspect 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 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 I.5 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.
I acknowledge and agree by my signature below that I am responsible for the performance of the five
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.
