Applicants Initials a. System is -located 50 feet from class SA waters and 30 feet from other surface waters. b. System is located at least 100 feet from water supply wells. c. Bottom of system is at least 2 feet above the seasonal high water table. h S d. Bottom of the system is 3 feet above any bedrock or impervious soil horizon. N -A e. Off-line system, runoff in excess of the design volume bypasses the system (bypass detail provided). 7Fi f. 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). W -4- g. Soils have a minimum hydraulic conductivity of 0.52 inches per hour. y0 -A--h. System is not sited -on or in fill material or DWQ approval has been obtained. i. 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. . -2'2 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. �b bG -2Ce o aQI�D k. 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. f2�9 1. System captures and infiltrates the runoff from the first 1.0 inch of rainfall (1.5 inch event for areas draining to SA waters ). �j G) m. Drainage area for the device is less than 5 acres. -A> n. A 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.

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 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 21-1 .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.

Depending on the types of activities occurring within the drainage area, most sand filters will show a decreased capacity for filtration after a few years. At least once a year, each filter must be inspected after a 1" design storm event to determine if the filter bed is passing the runoff within 24 hours. 2. If the filter is not passing the runoff completely within 24 hours, the first 2"-3" of discolored sand must be removed and replaced with new sand. The removed sand must be dewatered and disposed of properly. 3. At the same time that maintenance is performed on the sand chamber, the sediment chamber should be pumped and cleaned. The removed sediment should be dewatered and disposed of properly. 4. At least once every quarter, check that the orifice is clear.
