Applicants Initials GGr a. System is located 50 feet from class SA waters and 30 feet from other surface waters. G~e r b- System is located at least 100 feet from water supply wells. Ge_f c. Bottom of system is at least 2 feet above the seasonal high water table. C f d. Bottom of the system is 3 feet above any bedrock or impervious soil horizon. C f e. System is not sited on or in fill material DWQ approval has been obtained. e 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, IV o G L ! g. Drainage area for the device is less than 5 acres. ef C_ I h. Soils have a minimum hydraulic conductivity of 0.52 inches per hour and soils report is attached. G c_ ! i. System captures and infiltrates the runoff from the first 1.0 inch ofrainfall (1.5 inch event for areas draining to SA waters). Design volume and infiltration calculations attached. G"Lr j. System is sized to take into account the runoff at the ultimate built -out potential from all C4r surfaces draining to the system, including any off -site drainage. Calculations attached. k. All side slopes stabilized with vegetated cover are no steeper than 3:1 (I -IN), GGr 1. A pretreatment device such as a catch basin, grease trap, filter strip, grassed swale or sediment trap is provided. C'c- r m. Bottom of the device is covered with a layer o f elean sand to an average depth of 4 inches. or dense vegetative cover is provided f n. Vegetated filter is provided for overflow and detail is shown on plans (Required minimum length is 50 feet for SA waters, 30 feet for other waters & S o. Flow distribution mechanism within the basin is provided. p. A benchmark is provided to determine the sediment accumulation in the pretreatment device. q. Runoff in excess of the design volume bypasses off-line systems (bypass detail provided). r. System is designed to draw down the design storage volume to the proposed bottom elevation under seasonal high water conditions within five days. A soils report and all pertinent draw -down calculations are attached. G� I s. 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. Form SW U-103 Version 3.99 Page 2 of 3 HIV'. INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT After every runoff producing rainfall event and at least monthly inspect the infiltration system for erosion, trash accumulation, vegetative cover, and general condition. 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. After every runoff -producing rainfall event and at least monthly inspect the bypass, inflow and overflow stntctures 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 -excavation 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 planner 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 3 feet in the pretreatment unit, the sediment shall be removed from both the pretreatment unit and the infiltration basin. 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 21-1 A000 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.
