Infiltration basin shall be constructed level (at a 0-0.05% grade). Do not construct a basin on a slope greater than 15 percent. Do not locate within fill soils. Do not construct basin in a location with less than 2 feet between the bottom of the infiltration basin and the seasonal high groundwater table, underlying impervious soils, or bedrock (minimum 4 foot separation is nmmmeml,d). Basin shall mother constructed if it causes water problems to downgradient properties. It must be a minimum of 15 fed doWn- gradient from structures, located a minimum of 100 fed horizontally from any water supply well, 50 feet from Class SA waters and 30 feet from any surface water. 2 Pretreatment device for removing sediment and solids must be used to plate, t infiltration devices from clogging. These pretreatment devices include filter strips, grassed swales/ditdtes with check darts, corKrete sumps and forebays (sediment traps). 3. If Wet flow is a concentrated source of discharge, an energy dissipater shall be used. 4. A site-specific hydrogeologic investigation shall be performed to establish the wuimbility of soils for the infiltration basin. Suitable soils must have an infiltration rate of 0.52 inches per hour or greater. 5. Sizing of infiltration basin shall meet the specifications set forth in the NCDENR Stonnwater BMP Manuel and most be able th completely dissenter within 5 days. 6. The bottom of the infiltration basin most be lined with a layer of clean sand with a depth of 4 inches or greater, unless the native soil is equivalent (1 -2% fines or less). 7. Contractor shall use care during construction be minimize compaction of soil on the bottom and walls of the infiltration basin. light equipment and construction techniques that minnow compaction shall be used. 8- A minimum of one observation well shall be installed to periodically verify that the drainage media is fully draining. The monitoring well shall consist of a 4 to 6 inch diameter, perforated polyvinyl chloride (PVC) pipe with a locking cap. The well shall be placed rear the ranter of the facility or in the general location of the lowest point within the facility, with the invert at the excavated bottom of the facility. OPERATION AND MAIIYI'F.NANCE The drainage area shall be carefully managed be reduce the sediment load to the infiltration basin Immediately after the infiltration basin is established, the vegetation will be watered twice weekly if needed until the plants become established lecmmordy six weeks). No portion of the infiltration basin shall be fertilized after the Wltal fertilization required to establish the vegetation The vegetation in and around the basin will be maintained at a height of approximately six inches. Afar the infiltration basin is established, it shall be inspected once a quarter and within 24 hours after every storm event greater than 1.0 inches. Records of operation and maintenance shall he kept in a known set location and be available upon request Operation and Maintenance Provisions: 1. Remove any trasb/debris if present form the entire BMP. 2. If any areas of bare soil and /or erosive gullies have fanned around the perimeter of the infiltration basin, regrade the soil if necessary to remove the gully, then plant ground cover and provide a one time application of lime and fertilizer and water until established. 3. Dispose of any sediment and unclog B applicable any inlet pipe or swpee /ditch. if erosion is occurring in the swale/ditch regrade rte swale/ditch if necessary to smooth it over and provide erosion control devices such as reinforced turf matting or ripmp to avoid future problems with erosion 4. If sediment has accumulated in the forebay (sediment trap) and reduced the depth to 75% of the original design depth, find the source of the sediment and remedy the source. Remove the sediment and dispose of where it will not impact any drainage area. If erosion bas occurred or ripmp is displaced, provide additional erasion protection such as reinforced turf matting or additional ripmp to prevent future erosion. B weeds are present remove by hand if possible or use a selective herbicide to prevent killing of preferred ground cover. 5. B a visible layer of sediment has acctunulated in the main infiltration area, search for the source and remedy the problem. Remove the sediment and dispose of where it will not impact any drainage area. Replace any media that was removed in the process and nevegeate disturbed areas immediately. If water is standing more than 5 days after a stand event, replace the top few inches of filter media and we if this mneds the problem. If so revegetate immediately, if not consult an appropriate professional for a more extensive repair. B weeds or noxious pants are growing, remove the plants by hand or wipe with herbicide (do rut spiny). 6. B the embankment has shrubs or trees sprouting or growing, remove immediately, if the embankment requires repair during an annual inspection by an appropriate professional, make an needed repairs. 7. B the outlet device has clogged or is damaged, clean and dispose of the sediment properly and repair or replace the outlet device.

Infiltration basin shall be constructed level (at a 0-0.05% grade). Do not construct a basin on a slope greater than 15 percent. Do not locate within fill soils. Do not construct basin in a location with less than 2 feet between the bottom of the infiltration basin and the seasonal high groundwater table, underlying impervious soils, or bedrock (minimum 4 foot separation is nmmmeml,d). Basin shall mother constructed if it causes water problems to downgradient properties. It must be a minimum of 15 fed doWn- gradient from structures, located a minimum of 100 fed horizontally from any water supply well, 50 feet from Class SA waters and 30 feet from any surface water. 2 Pretreatment device for removing sediment and solids must be used to plate, t infiltration devices from clogging. These pretreatment devices include filter strips, grassed swales/ditdtes with check darts, corKrete sumps and forebays (sediment traps). 3. If Wet flow is a concentrated source of discharge, an energy dissipater shall be used. 4. A site-specific hydrogeologic investigation shall be performed to establish the wuimbility of soils for the infiltration basin. Suitable soils must have an infiltration rate of 0.52 inches per hour or greater. 5. Sizing of infiltration basin shall meet the specifications set forth in the NCDENR Stonnwater BMP Manuel and most be able th completely dissenter within 5 days. 6. The bottom of the infiltration basin most be lined with a layer of clean sand with a depth of 4 inches or greater, unless the native soil is equivalent (1 -2% fines or less). 7. Contractor shall use care during construction be minimize compaction of soil on the bottom and walls of the infiltration basin. light equipment and construction techniques that minnow compaction shall be used. 8- A minimum of one observation well shall be installed to periodically verify that the drainage media is fully draining. The monitoring well shall consist of a 4 to 6 inch diameter, perforated polyvinyl chloride (PVC) pipe with a locking cap. The well shall be placed rear the ranter of the facility or in the general location of the lowest point within the facility, with the invert at the excavated bottom of the facility. OPERATION AND MAIIYI'F.NANCE The drainage area shall be carefully managed be reduce the sediment load to the infiltration basin Immediately after the infiltration basin is established, the vegetation will be watered twice weekly if needed until the plants become established lecmmordy six weeks). No portion of the infiltration basin shall be fertilized after the Wltal fertilization required to establish the vegetation The vegetation in and around the basin will be maintained at a height of approximately six inches. Afar the infiltration basin is established, it shall be inspected once a quarter and within 24 hours after every storm event greater than 1.0 inches. Records of operation and maintenance shall he kept in a known set location and be available upon request Operation and Maintenance Provisions: 1. Remove any trasb/debris if present form the entire BMP. 2. If any areas of bare soil and /or erosive gullies have fanned around the perimeter of the infiltration basin, regrade the soil if necessary to remove the gully, then plant ground cover and provide a one time application of lime and fertilizer and water until established. 3. Dispose of any sediment and unclog B applicable any inlet pipe or swpee /ditch. if erosion is occurring in the swale/ditch regrade rte swale/ditch if necessary to smooth it over and provide erosion control devices such as reinforced turf matting or ripmp to avoid future problems with erosion 4. If sediment has accumulated in the forebay (sediment trap) and reduced the depth to 75% of the original design depth, find the source of the sediment and remedy the source. Remove the sediment and dispose of where it will not impact any drainage area. If erosion bas occurred or ripmp is displaced, provide additional erasion protection such as reinforced turf matting or additional ripmp to prevent future erosion. B weeds are present remove by hand if possible or use a selective herbicide to prevent killing of preferred ground cover. 5. B a visible layer of sediment has acctunulated in the main infiltration area, search for the source and remedy the problem. Remove the sediment and dispose of where it will not impact any drainage area. Replace any media that was removed in the process and nevegeate disturbed areas immediately. If water is standing more than 5 days after a stand event, replace the top few inches of filter media and we if this mneds the problem. If so revegetate immediately, if not consult an appropriate professional for a more extensive repair. B weeds or noxious pants are growing, remove the plants by hand or wipe with herbicide (do rut spiny). 6. B the embankment has shrubs or trees sprouting or growing, remove immediately, if the embankment requires repair during an annual inspection by an appropriate professional, make an needed repairs. 7. B the outlet device has clogged or is damaged, clean and dispose of the sediment properly and repair or replace the outlet device.

Infiltration basin shall be constructed level (at a 0-0.05% grade). Do not construct a basin on a slope greater than 15 percent. Do not locate within fill soils. Do not construct basin in a location with less than 2 feet between the bottom of the infiltration basin and the seasonal high groundwater table, underlying impervious soils, or bedrock (minimum 4 foot separation is nmmmeml,d). Basin shall mother constructed if it causes water problems to downgradient properties. It must be a minimum of 15 fed doWn- gradient from structures, located a minimum of 100 fed horizontally from any water supply well, 50 feet from Class SA waters and 30 feet from any surface water. 2 Pretreatment device for removing sediment and solids must be used to plate, t infiltration devices from clogging. These pretreatment devices include filter strips, grassed swales/ditdtes with check darts, corKrete sumps and forebays (sediment traps). 3. If Wet flow is a concentrated source of discharge, an energy dissipater shall be used. 4. A site-specific hydrogeologic investigation shall be performed to establish the wuimbility of soils for the infiltration basin. Suitable soils must have an infiltration rate of 0.52 inches per hour or greater. 5. Sizing of infiltration basin shall meet the specifications set forth in the NCDENR Stonnwater BMP Manuel and most be able th completely dissenter within 5 days. 6. The bottom of the infiltration basin most be lined with a layer of clean sand with a depth of 4 inches or greater, unless the native soil is equivalent (1 -2% fines or less). 7. Contractor shall use care during construction be minimize compaction of soil on the bottom and walls of the infiltration basin. light equipment and construction techniques that minnow compaction shall be used. 8- A minimum of one observation well shall be installed to periodically verify that the drainage media is fully draining. The monitoring well shall consist of a 4 to 6 inch diameter, perforated polyvinyl chloride (PVC) pipe with a locking cap. The well shall be placed rear the ranter of the facility or in the general location of the lowest point within the facility, with the invert at the excavated bottom of the facility. OPERATION AND MAIIYI'F.NANCE The drainage area shall be carefully managed be reduce the sediment load to the infiltration basin Immediately after the infiltration basin is established, the vegetation will be watered twice weekly if needed until the plants become established lecmmordy six weeks). No portion of the infiltration basin shall be fertilized after the Wltal fertilization required to establish the vegetation The vegetation in and around the basin will be maintained at a height of approximately six inches. Afar the infiltration basin is established, it shall be inspected once a quarter and within 24 hours after every storm event greater than 1.0 inches. Records of operation and maintenance shall he kept in a known set location and be available upon request Operation and Maintenance Provisions: 1. Remove any trasb/debris if present form the entire BMP. 2. If any areas of bare soil and /or erosive gullies have fanned around the perimeter of the infiltration basin, regrade the soil if necessary to remove the gully, then plant ground cover and provide a one time application of lime and fertilizer and water until established. 3. Dispose of any sediment and unclog B applicable any inlet pipe or swpee /ditch. if erosion is occurring in the swale/ditch regrade rte swale/ditch if necessary to smooth it over and provide erosion control devices such as reinforced turf matting or ripmp to avoid future problems with erosion 4. If sediment has accumulated in the forebay (sediment trap) and reduced the depth to 75% of the original design depth, find the source of the sediment and remedy the source. Remove the sediment and dispose of where it will not impact any drainage area. If erosion bas occurred or ripmp is displaced, provide additional erasion protection such as reinforced turf matting or additional ripmp to prevent future erosion. B weeds are present remove by hand if possible or use a selective herbicide to prevent killing of preferred ground cover. 5. B a visible layer of sediment has acctunulated in the main infiltration area, search for the source and remedy the problem. Remove the sediment and dispose of where it will not impact any drainage area. Replace any media that was removed in the process and nevegeate disturbed areas immediately. If water is standing more than 5 days after a stand event, replace the top few inches of filter media and we if this mneds the problem. If so revegetate immediately, if not consult an appropriate professional for a more extensive repair. B weeds or noxious pants are growing, remove the plants by hand or wipe with herbicide (do rut spiny). 6. B the embankment has shrubs or trees sprouting or growing, remove immediately, if the embankment requires repair during an annual inspection by an appropriate professional, make an needed repairs. 7. B the outlet device has clogged or is damaged, clean and dispose of the sediment properly and repair or replace the outlet device.
