Coverage under the State Construction General Permit 3-9020 is required for any construction activity that disturbs 1 or more acres of land, or is part of a larger development plan that will disturb 1 or more acres. This project is subject to a moderate risk authorization in coordination with the activities located on lot 1G- Booska Movers This project requires an Individual Permit which is subject to the erosion prevention and sediment control (EPSC) standards set for in the State of Vermont's Standards and Specifications for Erosion Prevention and Sediment Control The following narrative and implementation requirements represent the minimum standard for which this site is required to be maintained as regulated by the State of Vermont. Any best management practices (BMP's) depicted on the project's EPSC Site plan which go beyond the Handbook requirements are considered to be integral to the management of the site and represent components of the municipal EPSC approval for the project which shall be implemented. The EPSC plan depicts one snap shot in time of the site. All construction sites are fluid in their day to day exposures and risks as it relates to minimizing sediment loss from the site. It is the responsibility of the Contractor to implement the necessary BMP's to comply with the Erosion Prevention and Sediment Control Field Guide standards outlined on this sheet based on the interim site disturbance conditions which may or may not be shown on the EPSC Site Plan. This project is authorized to disturb up to 2.3 acres 1. Pre-Construction Planning Planning your construction project can help you avoid costly mistakes in controlling erosion and sediment loss to nearby waterways. Follow the steps below before you begin clearing, grading, and excavation work. If your project is one acre or larger, you will need a construction stormwater permit from the Vermont Department of Environmental Conservation (VT DEC) Stormwater Section (802-828-1535, or see dec.vermont.gov/watershed/stormwater) Assess soils and slopes on the construction site The erosion potential on your construction site depends in part on the soil type and slope steepness at your site. See the table below. Note: there are other factors that contribute to erosion, such as slope length and rainfall intensity and duration. Also, even though there may be low potential for erosion, there can be a high risk to water quality when the soil disturbance is close to water resources Identify nearby streams and drainage control points Walk over the site and find where ditches or other concentrated flows leave the site. These are the final sediment control points. Sediment traps or basins should be installed just above these control points. Your site may drain to an underground storm sewer system. In this case, the storm drain inlets that drain runoff from your site are the control points and must be protected (see Section 7). These are also the compliance points for any permits issued for the site. Install clean water diversions, sediment traps/ basins, grassed ditches, silt check dams, and sediment barriers such as silt fences before clearing and excavation work begins! Preserve existing vegetation wherever possible Only dig or grade where necessary. Existing trees, bushes, and grass help keep erosion to a minimum. Protect large trees by marking off a no-dig root protection zone that is twice as large as the outer perimeter of the branches. Plan your project to limit the amount of bare soil area exposed to the weather, and limit the amount of exposure time. Do not clear vegetation or excavate areas near streams, rivers, lakes, or wetlands without getting the required state and federal permits! Preserve vegetated buffers Preserve existing vegetation near waterways wherever possible. This vegetation is the last barrier to capture sediment runoff before it enters the lake, river, stream, or wetland. Where vegetation has been removed or where it is absent, plant native species of trees, shrubs, and grasses. Design projects to fit the natural topography Minimize clearing and grading to preserve mature vegetation and save money. Identify natural landscape features you want to keep, like large trees, wildflower areas, grasslands, streams, and wetlands. Plan ways to fit your project around these features, so they remain in place after construction is completed. Be sure to mark off these areas with colored ribbon or stakes and warn equipment operators of their location! Minimize impervious surfaces Keep the amount of roof area, parking lots, driveways, and roads to a minimum. Design these hard surfaces so that rain water they collect is directed onto landscaped or yard areas, not into ditches or streams. For example, design roads slightly higher than adjacent lawn areas, and use swales instead of curbs along roadways. Promote infiltration in project design Moving storm water runoff from hard surfaces to landscaped or yard areas helps runoff soak into the soil. This promotes groundwater recharge, filters sediment and other pollutants from runoff, and helps to prevent flooding. Develop an erosion and sediment control plan Develop a written site plan for your project that shows the drainage patterns and slopes, areas of disturbance (cuts/fills, grading), location of erosion and sediment controls, location of surface waters and wetlands, and the location of storm water drainage control points. Your site plan must be updated as conditions change at the site. Design specifications for erosion prevention and sediment control are included in the Vermont Standards and Specifications for Erosion Prevention and Sediment Control. This manual is available for download at: dec.vermont.gov/watershed/stormwater. 2. Construction Phase Operations Divide your construction site into natural drainage areas, so you can deal with each one individually. You will be controlling erosion on bare soil areas by applying seed, mulch, or sediment barriers, and minimizing the time bare soil is exposed to the weather. Control points for sediment in runoff will be at the curb inlets or in the ditches, channels, or sediment traps/basins installed where concentrated flow leaves the site. Install clean water diversions, sediment traps/ basins and stabilize drainage channels with grass, liners, and silt check dams before excavation, fill, or grading work begins (see Section 8). Install silt fences and other sediment barriers downhill from bare soil areas before clearing or excavation work begins (see Section 5). Phase your construction work to minimize exposed soil areas Excavate or place fill material at the site in stages, to avoid exposing large areas of bare soil to the elements. Projects should be cleared and graded as construction progresses. Check your EPSC Plan for your site's permitted disturbance area. Establish final grade quickly, then seed, mulch, or cover bare soil. If work will proceed over several weeks or months, apply temporary seeding or mulch until final grade work is completed. Seed and mulch as soon as possible and as per your permit requirements. Excavation and grading work should be done during dry weather if possible. Prepare for rainy weather by making sure sediment controls are in place and that all exposed areas are mulched. Install construction entrances and control dust Mud tracked onto roads is the number one complaint from citizens regarding construction site operations. Use a matrix of 1 to 4 inch stone for entrance/exit pads leading to roads. Pads should be at least 12 feet wide, 40 feet long, and 8 inches deep. Entrance pads shall not be narrower than the construction entrance. On residential properties, pads may be shorter than 40 feet, as long as they are the length of the driveway. Install filter fabric under the rock to keep it from sinking into the soil below. Rake rock with a grubbing attachment or add new rock if the pad fills with sediment. Control dust during hot, dry weather by seeding or mulching bare areas promptly or by wetting haul roads as needed. Dewatering operations and discharges Water pumped from collection basins or other areas must not be pumped into storm sewers, streams, lakes, or wetlands unless sediment is removed prior to discharge. Discharges to streams, lakes, wetlands, or storm sewers needs to be part of the authorized EPSC Plan. Use sock filters or sediment filter bags on discharge pipes, discharge water into silt fence enclosures installed in vegetated areas away from waterways, or discharge water into a de-silting basin. Remove accumulated sediment after water has dispersed and stabilize or seed the discharge area. Dispose of sediment in areas where it won't wash into waterways, then grade the area and seed. Inspection and maintenance of EPSC practices For sites one acre or larger, the Vermont Construction General Permit requires that you regularly inspect and repair/replace all sedimentation and erosion control measures identified in the EPSC Plan. Discharge locations must also be inspected to ascertain whether erosion control measures are effective in preventing significant impacts to waters of the State. Your inspection reports must be in writing, and kept with your EPSC Plan at the site. Refer to your construction permit for inspection requirements. 3. Diverting Runoff Around Exposed Soils Keep clean runoff from flowing through your construction site, or route it through stable ditches so it won't pick up sediment. Below are some simple, interchangeable approaches for dealing with upland sources of runoff. Earth Dikes An earth dike or berm is a long, mounded “collar” of compacted soil located uphill from the excavated area. The dike is designed to intercept overland runoff and direct it around the construction site. This prevents “clean” water from becoming muddied with soil from the construction site. Earth dikes can be temporary or permanent landscape features of the site. Design Criteria Channel Stabilization Construction Specifications 1. Compact the dike with earth-moving equipment. 2. Stabilize the channel as per the specifications in the table within 48 hours of installation. 3. Top width may be wider and side slopes flatter if desired to facilitate crossing by construction traffic. 4. Ensure the dike has positive drainage to an outlet. 5. Ensure that there is no erosion at the outlet. 6. Runoff shall be conveyed to a sediment trapping device if the dike channel or drainage area above the dike is not adequately stabilized. 7. The earth dike shall remain in place until the disturbed areas are completely stabilized. Diversion Swales Diversion swales are similar to dikes12/20/2019they are designed to intercept and divert upland runoff around bare soil areas. Swales are cut above cleared or fill areas and designed with a gentle slope to carry water away from work areas. Stabilized, lined swales can also be used to move upland water through your site without getting muddy. Construct and line “pass-through” swales before general clearing or grading work begins. Swales should discharge to areas with thick vegetation or flat surfaces to promote dispersal and infiltration. Gullies must be repaired as soon as they appear. Channel Stabilization (see Earth Dike) Construction Specifications 1. Compact the swale with earth-moving equipment. 2. Stabilize the swale as per the specifications for channel stabilization (see Earth Dike). 3. Ensure that the swale has uninterrupted positive drainage to an outlet. 4. Ensure that there is no erosion at the outlet. 5. Diverted runoff from a disturbed area shall be conveyed to a sediment trapping device. 6. All earth removed and not needed for construction shall be stabilized and placed so that it will not interfere with the functioning of the swale. Perimeter Dike and Swale A perimeter dike is a temporary ridge of soil excavated from an adjoining swale located along the perimeter of the site or disturbed area. Design Criteria Drainage area - less than 2 acres Height - 18 inches minimum (measure from bottom of swale to top of dike) Bottom width of dike - 2 feet minimum Width of swale - 2 feet minimum Grade - not to exceed 8%. Swale shall have positive drainage to a stabilized outlet. Construction Specifications 1. Stabilize the dike and swale within 48 hours of installation. 2. Install berm on the contour (along the slope). 3. Diverted runoff from a stabilized upland area shall outlet directly onto an undisturbed, stabilized area at a non-erosive velocity. 4. Diverted runoff from a disturbed upland area shall be conveyed to a sediment trapping device. Water Bar A water bar is a ridge or a ridge and channel constructed diagonally across a sloping road that is subject to erosion. Water bars limit the erosive velocity of water by diverting surface runoff at predesigned intervals. Water Bar Design Criteria Height - 18 inches min height (measure from channel bottom to ridge top) Side Slopes - 2:1 or flatter; 4:1 where vehicles cross Base width of ridge - 6 feet min Grade of water bar - not to exceed 2% Construction Specifications 1. Install the water bar as soon as the road or trail is cleared and graded. 2. Disk or strip the sod from the base for the constructed ridge before placing fill. 3. Track the ridge to compact it to the design cross section. 4. The outlet shall be located on an undisturbed area. Field spacing will be adjusted to use the most stable outlet areas. Outlet protection will be provided when natural areas are not adequate. 5. Vehicle crossing shall be stabilized with gravel. Exposed areas shall be immediately seeded and mulched. 6. Periodically inspect water bars for erosion damage and sediment. Check outlet areas and make repairs as needed to restore operation. 4. Protecting Soils With Seed, Mulch, or Other Products Seeding or covering bare soil with mulch, erosion control matting or blankets, or other products as soon as possible is the cheapest and best way to prevent erosion. Grass seeding alone can reduce erosion by more than 90 percent. The following practices can be used interchangeably for stabilizing exposed soil. Soil cover requirements All areas of disturbance must have temporary or permanent stabilization within 7 days of initial disturbance. After this time, any disturbance in the area must be stabilized at the end of each work day. The following exceptions apply: Stabilization is not required if earthwork is to continue in the area within the next 24 hours and there is no precipitation forecast for the next 24 hours. Stabilization is not required if the work is occurring in a self-contained excavation (i.e. no outlet) with a depth of 2 feet or greater (e.g. house foundation excavation, utility trenches). All areas of disturbance must have permanent stabilization within 48 hours of reaching final grade. NOTE: If the authorization you receive has more protective time limits, then those must be followed. Seed types and application Prepare bare soil for planting by disking across slopes, scarifying, or tilling if soil has been sealed or crusted over by rain. Seedbed must be dry with loose soil to a depth of 12 inches. Soil amendments should be incorporated into the upper 2 inches of soil when feasible. The soil should\ be tested to determine the amounts of amendments needed. Apply ground agricultural limestone to attain a pH of 6.0 in the upper 2 inches of soil. Check seed bag tags to make sure correct seed is used. Mix seed thoroughly prior to loading seeders. Use the following tables to calculate seed application rates and mixture portions. Apply seed by hand, seeder, drill, or hydroseed. Drilled seed should be . inch deep. Mulch seeded areas as soon as possible. Apply more seed to channels, ditches, lawn, and landscaped areas. Apply less seed to areas that are flat or that will not be mowed very often. Water seeded areas during dry conditions to ensure seed germination and early growth. Re-seed areas that do not show growth within 14 days after rain or watering. Protect bare areas during the winter by sowing winter rye at 120 lbs per acre (2.0 lbs/1000 sq. ft.). Seed by September 15 to ensure vegetative cover for winter. Seed mixes for wildflower and native plant plots are also available. They are more expensive, but are very hardy, require little mowing or watering, and add beauty to landscaped and other areas. Most mixes require mowing only once per year, to control tree and brush growth. For slopes steeper than 3:1, walk bulldozer or other tracked vehicle up and down slopes before seeding to create tread-track depressions for catching and holding seed. Mulch slopes after seeding to conserve moisture and provide initial erosion control. Mulch types and application Mulch by itself or applied over seed provides excellent erosion protection (see table). To apply, bring site to final grade and clear rocks, wood, trash, and other debris. Apply seed first. Straw or hay should be hand scattered or blown to obtain a depth of 1 inch (see table). In winter, straw or hay mulch should be applied to obtain a depth of 3 inches. Wood chips or shavings should be applied to a depth of 2 inches. In general, apply mulch so that at least 80 to 90 percent of the ground is covered. *Perform regular maintenance and reapply mulch as needed to ensure bare soil is 80 to 90% covered. Erosion control blankets Erosion control blankets are used to protect steep slopes (up to 3:1; check product information sheets), drainage ditches with less than 20:1 slopes, and other areas where erosion potential is high. Most are designed to provide temporary stabilization until vegetation is established. Blankets degrade within 6 to 24 months, depending on their makeup. They usually consist of a layer of straw, coconut fiber, wood fiber, or jute sandwiched between layers of plastic or fiber mesh. For short slopes (8 feet or less) above channels, install blankets across the slope (horizontal). Install up and down the hill (vertical) for long slopes. Walk blankets down to ensure good contact with the soil. Use plenty of staples to keep blankets flat. Overlap blankets at 6 to 8 inches on sides, tops, and bottoms. Do not stretch blankets, and do not exceed manufacturer's directions on maximum slope angle for the product. Turf reinforcement mats Turf reinforcement mats are similar to erosion control blankets, but are thicker and sturdier because they have more layers and sturdier fill material. Mats provide greater protection than blankets because of their heavier construction, and last longer in the field. Mats are used for steep slopes (3:1 or steeper) and ditches or channels with 15:1 to 10:1 slopes. Mats are installed just like blankets (see previous table). Additional staking or stapling is needed for applications in channels that carry flowing water, and on steep slopes. Sod application Sod reduces the potential for erosion to near zero. To install, bring soil to final grade and clear of trash, wood, rock, and other debris. Test soil, apply topsoil and fertilize in accordance with soil test results. Use sod within 36 hours of cutting. Lay sod in straight lines. Butt joints tightly, but do not overlap joints or stretch sod. Stagger joints in adjacent rows in a brickwork type pattern. Use torn or uneven pieces on the end of the row. Notch into existing grass. On sloping areas where erosion may be a problem, sod shall be laid with the long edges parallel to the contour and with staggered joints. Roll or tamp sod after installation and water immediately. Soak to a depth of 4 to 6 inches. Replace sod that grows poorly. Do not cut or lay sod in extremely wet or cold weather. Do not mow regularly until sod is well established. Bonded Fiber Matrices Other engineered products are available that are similar to blankets and mats. For example, bonded fiber matrices and other hydraulically applied products contain a mix of soil binders, mulch fibers, and even seed and fertilizer that can provide a stable crust that cements soil particles and prevents erosion. Apply seed prior to hydraulic mats or mulches, if seed is not included in the mix. Consult the manufacturer's installation instructions for product applicability and installation instructions. 5. Using Silt Fence and Other Sediment Barriers The use of silt fences and other sediment barriers involves simple observation and common sense. However, as Will Rogers once noted, “common sense ain't so common.” The following practices may be used as interchangeable sediment barriers. Sediment barrier placement Sediment barriers are required below (downhill from) areas of bare soil. Hay or straw bales must not be used as sediment barriers due to their inherent weakness and tendency to fall apart. There are several factors to consider in placing silt fences or perimeter dikes and swales: Place barriers on downhill edge of bare soil areas. Make sure the barrier catches all the runoff. The goal is to intercept runoff and settle sediment out. Install multiple sediment barriers on long slopes. Put barriers across slopes, on the contour (level). Silt Fence Each 100-foot section of silt fence can intercept runoff from about .25 acres. To install a silt fence correctly, follow these steps: Note the location & extent of the bare soil area. Mark silt fence location just below bare soil area or 10 feet below the bottom of a steep slope. Make sure fence will catch all flows from area. Place fence across the slope. Dig trench 6 inches deep and 4 inches wide. Unroll silt fence along trench. Join fencing by rolling the end stakes together. Make sure stakes are on downhill side of fence. Drive stakes in against downhill side of trench. Drive stakes until 16 inches of fabric is in trench. Push fabric into trench; spread along bottom. Fill trench with soil and tamp down. Silt fencing should not be installed: Up and down hills. Above (uphill from) areas of bare soil. In ditches, channels, or streams. In stream buffers. Directly at the toe (bottom) of the slope. Additional storage capacity is needed and can be provided for by placing the fence 10 feet below toe. (Place fence directly at toe if near water or stream buffer) If runoff flows along the uphill side of a silt fence, install “J-hooks” every 40 to 80 feet. These are curved sections of silt fence that act as small dams to stop, pond, and settle out flows. Maximum allowable slope lengths contributing runoff to a silt fence placed on a slope Silt fence slicing devices New tractor-mounted equipment that “slices” silt fence into the ground can provide a better installation than the open trench method. The equipment uses a chisel-point or vibratory plow to create a narrow slit in the ground. Rolled silt fencing is pushed into the slit, creating a very tight seal that prevents water from blowing out the bottom of the fence. Posts are driven and attached to the fence after the fencing is installed. Besides better performance, the slicing method is also faster. For slicing and all other applications, posts are spaced 6 feet apart or less. Perimeter Dike and Swale A perimeter dike is a temporary ridge of soil excavated from an adjoining swale located along the perimeter of the site or disturbed area. The purpose of a perimeter dike and swale is to prevent off site storm runoff from entering a disturbed area and to prevent sediment laden storm runoff from leaving the construction site or disturbed area. Perimeter Dike and Swale Design Criteria Drainage area - less than 2 acres Height - 18 inches minimum (measure from bottom of swale to top of dike) Bottom width of dike - 2 feet minimum Width of swale - 2 feet minimum Grade - not to exceed 8%. Swale shall have positive drainage to a stabilized outlet. Construction Specifications 1. Stabilize the dike and swale within 48 hours of installation. 2. Install berm on the contour (along the slope). 3. Diverted runoff from a stabilized upland area shall outlet directly onto an undisturbed, stabilized area at a non-erosive velocity. 4. Diverted runoff from a disturbed upland area shall be conveyed to a sediment trapping device. 6. Protecting Slopes to Prevent Gullies Slopes12/20/2019especially long ones12/20/2019must be protected to prevent sheet, rill, and gully erosion. Slopes must be stabilized immediately after grading work is completed. The following practices can be used interchangeably to protect and stabilize slopes: The following practices are included in this section for informational purposes only. Consult the EPSC Plan designer or engineer for design and installation specifications. Pipe Slope Drain Subsurface Drain Lined Waterway Engineered Terracing Surface Roughening Retaining Wall Fiber Roll Assessing slopes and soils Steeper slopes (3:1 or steeper) require more protection than flatter slopes. Slopes with highly erodible soils (silty soils) need more protection than those with less erodible soils (sands and gravels). Also, long slopes (greater than 50 feet) are at greater risk for erosion than short slopes. Slope protection basics Protecting slopes from erosion requires several actions that must be taken together. No single approach will be successful, especially if the slope is long, steep, or has highly erodible soils. Use one or more of the following actions to reduce erosion on slopes: Divert upland runoff See Section 3 for information on how to install a berm or channel above the slope to divert upland rain runoff around the bare soil area. Control slope runoff If slopes are broken up into benches or steps, runoff can be collected and diverted along berms or in channels to pipe or open channel slope drains with stable outlets. Till seedbed or condition the soil Dozer tracks up and down slopes help hold soil in place and lengthen the runoff flow path down the slope. See Section 4 for information on how to condition of the soil surface. Seed and mulch The best and cheapest protection by far. See Section 4 for details on seed types, application rates, and mulch, blanket, and mat products. Silt fence or other barrier These should be installed at the toe of the slope or slightly away from the toe. Multiple fences should be installed on long slopes. Fiber rolls installed on the contour work very well in breaking up flows on long slopes. Retaining wall Extremely steep slopes can be leveled out and shortened into two or more steps or benches by installing retaining walls of rock, brick, block, wood, logs, or other material. If rock layers are present along the slope, use these to establish firm benches in a stair-step pattern. Blankets, mats, or armoring Slopes exceeding 3:1 with highly erodible soils must be protected with turf reinforcement mats or other products such as hydraulic soil binders or bonded fiber matrices. Rock mulch and lined downdrain channels might be needed on steep slopes to control gullying. Erosion Control Blankets and Mats Steep slopes can be protected with erosion control mats and blankets. Erosion control matting and blankets are appropriate for slopes up to a 3:1 steepness. For slopes greater than 3:1, use turf reinforcement mats. (See Section 4 for installation details). Hydraulic mulch Bonded fiber matrices and hydraulic mulch can be very effective in controlling erosion on slopes. Hydraulic mulch applied after seeding or with seed in the mix can provide permanent protection if mixed and applied properly. (See Section 4 for details) Rock Gabions Rock Gabions are wire 'baskets' filled with rock used to permanently stabilize slopes. Gabion baskets should be filled with 4 - 8 inch stone and layered according to manufacturers recommendations. Riprap Slope Protection Riprap is a layer of stone designed to protect and stabilize areas subject to erosion. Riprap is used in areas where vegetation cannot be established. Follow your EPSC Plan design specifications for installation. Additional Practices for Protecting Slopes The following practices are included in this section for informational purposes only. Consult the EPSC Plan designer or engineer for design and installation specifications. Pipe Slope Drain A pipe slope drain is a temporary structure placed from the top to the bottom of a slope to convey runoff down the slope without causing erosion. Subsurface Drain A subsurface drain is a conduit, such as a tile, pipe, or tubing installed beneath the ground surface that intercepts, collects, and/or conveys drainage water. Stone Lined Waterway A stone lined waterway is a channel that carries water down a slope to prevent slope erosion or gullying. Engineered Terracing Terracing is the reshaping of the existing land surface to control erosion and promote the establishment of vegetation. Surface Roughening Roughening bare soil by creating horizontal grooves across a slope, stair-stepping, or tracking with construction equipment aids in seed establishment, reduces runoff velocity, increases infiltration, and reduces erosion by trapping water and sediment. Retaining Wall A retaining wall is constructed against a slope to prevent soil movement. It retains soil in place and prevents slope failures and movement of material down steep slopes. Retaining walls can be built from mortared block or stone, cast-in-place concrete, railroad ties, gabions, and precast, modular, segmented walls. The design of any retaining wall structure must address the aspects of foundation bearing capacity, sliding, overturning, drainage, and loading systems. These are complex systems and all but the smallest retaining walls should be designed by a licensed engineer. Fiber Roll A fiber roll is a woven roll of coconut fiber, straw, or excelsior encased in a netting of jute, nylon, or burlap. Fiber rolls can be used to break up runoff flows on long slopes. 7. Protecting Culvert and Ditch Inlets and Outlets Culverts and ditches are designed to carry moderate and large flows of storm water. They can transport a lot of sediment to streams, rivers, wetlands, and lakes if they are not properly protected. In addition, culvert and ditch outlets can become severely eroded if high velocity flows are not controlled. Culvert and storm drain ponding methods Muddy runoff that flows toward a culvert, ditch, or storm drain inlet must be slowed down and pooled to settle out and remove sediment. This can be accomplished by placing rock, reinforced silt fencing, silt dikes, or other barrier in front of the inlet. The goal is to cause ponding of the inflow so sediment can settle out, and allow ponded water to enter the inlet only after sediment has been removed. Straw bales alone are not approved for inlet protection. The maximum drainage area above the inlet protection device is one acre. For all inlet protection approaches, seeding and/or mulching upland areas promptly will greatly reduce incoming runoff volumes and sediment loads. The drainage area for storm drain inlets shall not exceed one acre. All inlet protection practices should be inspected after storm events and repaired as necessary. Accumulated sediment should be removed when 50% of ponding volume is lost. The following are interchangeable practices for inlet protection: Excavated drop inlet protection Side slopes - maximum steepness 2:1 Depth - minimum 1 foot; maximum 2 feet Shape the excavated basin to fit conditions with the longest dimension oriented toward the longest inflow area to provide maximum trap efficiency. The capacity of the excavated basin, below the level of the grate, should be established to contain 900 cubic feet per acre of disturbed area. Weep holes, protected by fabric and stone, should be provided for draining the temporary pool. Inspect and clean the excavated basin after every storm. Sediment should be removed when 50 percent of the storage volume is lost. Filter fabric drop inlet protection Slope around device - Not to exceed 1% Height of fabric - 1.5 feet max., (unless reinforced). The top of the barrier should be maintained to allow overflow to drop into the drop inlet and not bypass the inlet to unprotected lower areas. Support stakes - 3 feet min., spaced max 3 feet apart; Stakes should be driven close to the inlet so overflow drops into the inlet and not on the unprotected soil. 1. Filter fabric shall have an equivalent opening size (EOS) of 40-85. 2. Cut fabric from a continuous roll to eliminate joints. 3. Stakes will be standard 2 x 4 inch wood or metal with a minimum length of 3 feet. 4. Space stakes evenly around inlet, 3 feet apart and 18 inches deep. Spans greater than 3 feet should be reinforced with wire mesh. 5. Fabric shall be embedded at least 1 foot in ground and backfilled. It should be secured to the stakes. 6. A 2 x 4 inch wood frame shall be completed around the crest of the fabric for overflow stability. Stone and block drop inlet protection Height - 1 foot min., 2 feet max. Limit the height to prevent excess ponding and bypass flow. Block placement - Recess the first row of blocks at least 2 inches below the top of the storm drain for lateral support. Blocks can also be supported by placing a 2x4 inch wood stud through the block openings perpendicular to the row. The bottom row should have a few blocks oriented so flow can drain through the block to dewater the basin area. Stone placement - Place stone just below the top of the blocks on slopes of 2:1 or flatter. Place hardware cloth of wire mesh with . inch openings over all block openings to hold stone in place. Optional "doughnut" design - The concrete blocks may be omitted and the entire structure constructed of stone, ringing the outlet. The stone should be kept at a 3:1 slope toward the inlet to keep it from being washed into the inlet. A level area 1 foot wide and four inches below the crest will further prevent wash. Stone size for "doughnut" - At least 3 inches closest to the inlet, for stability; 1 inch or smaller around the larger rock to control flow rate. Elevation for "doughnut" - The top of the stone should be 6 inches lower than the ground elevation down slope from the inlet to ensure that all storm flows pass over the stone into the storm drain and not past the structure. Temporary diking should be used as necessary to prevent bypass flow. Curb drop inlet protection Stone size - 2 inches Wire mesh - of sufficient strength to support the filter fabric and stone with the water fully impounded against it. Filter fabric - type approved for this purpose with an equivalent opening size (EOS) of 40-85. Length of structure - must extend beyond the inlet 2 feet in both directions. Assure that storm flow does not bypass the inlet by installing temporary dikes (such as sand bags) directing flow into the inlet. Make sure that the overflow weir is stable. Traffic safety shall be integrated with the use of this practice. The structure should be inspected after every storm event. Any sediment should be removed and disposed of on the site. Any stone missing should be replaced. Check materials for proper anchorage and secure as necessary. Outlet protection methods Outlets for storm drains, culverts, and paved channels that discharge into natural or constructed channels must be lined with rock or other armoring to prevent downstream bank and channel erosion when flow velocities are high. The following practices are included in this section for informational purposes only. Consult the EPSC Plan designer or engineer for design and installation specifications. Rock Outlet Protection Paved Flume Level Spreader Rock outlet protection Rock placed at the end of culvert reduces the depth, velocity, and energy of water, such that the flow will not erode the receiving downstream reach. Paved Flume A paved flume is a small concrete-lined channel designed to convey concentrated runoff safely down the face of a relatively steep slope without causing erosion.

Stabilizing Drainage Ditches Stabilizing drainage ditches helps to provide for the safe transport of excess surface water from the construction sites and urban areas without damage from erosion. This section is divided into 3 parts: Vegetating Low Grade Channels, Protecting Steep Channels, and Installing Check Dams Interchangeable practices are provided for Vegetating Channels and Installing Check Dams. Practices for Protecting Steep Channels are included in this section for informational purposes only. Consult the EPSC Plan designer or engineer for design and installation specifications for steep channel protection. Vegetating Low Grade Channels Vegetating drainage channels helps to reduce the velocity of the channelized runoff and limit the erosion potential. The following practices can be used interchangeably to vegetate low grade channels. Seed and Mulch To establish vegetation in a channel, seed and mulch using the guidance in Section 4. Prepare the soil for seeding and ensure that vegetation is well established before water is diverted to the channel. SECTION Rolled Erosion Control Products (RECPs) Rolled Erosion Control Products (RECPs) include erosion control mats, turf reinforcement mats, and jute and excelsior matting. RECPs should be used in channels with flow velocities up to 3.5 feet/sec. See Section 4 for installation instructions and seeding information. Sodding Sod can also be used in low grade channels to reduce runoff velocities and minimize erosion potential. See Section 4 for sod installation instructions and specifications. Protecting Steep Channels Channels with grades steeper than 3:1 may need additional armoring to prevent downcutting and erosion. The following practices are included in this section for informational purposes only. Consult the EPSC Plan designer or engineer for design and installation specifications. Rock Lining Grade Stabilization Structure Rock Lining Riprap lined channels provide for the transport of concentrated runoff without damage from erosion, where vegetated channels would be inadequate due to high velocities. Grade Stabilization Structure Grade stabilization structures control head cutting in natural or man made channels. They are designed to limit erosion by reducing velocities and grade in the watercourse. Installing Check Dams Drainage ditches need temporary check dams to capture sediment and reduce ditch bottom downcutting. The following are interchangeable types of check dams. Silt fencing and hay bales are not approved for use as check dams, and must not be used in drainage ditches that carry flowing water. Also, do not place dams in creeks or streams. Sediment must be intercepted before it reaches streams, lakes, or wetlands. Design Criteria Drainage Area: Maximum 2 acres Height: No greater than 2 feet. Center of dam should be 9 inches lower than the side elevation Side slopes: 2:1 or flatter Spacing: Space the dams so that the bottom (toe) of the upstream dam is at the elevation of the top (crest) of the downstream dam. This spacing is equal to the height of the check dam divided by the channel slope. Spacing (in feet) = Height of check dam (in feet) Slope in channel (ft/ft) Check dams should be anchored in the channel by a cutoff trench 1.5 feet wide and 0.5 feet deep and lined with filter fabric to prevent soil migration. Maintenance: Check dams should be inspected after each runoff event. Correct all damage immediately. If significant erosion has occurred between structures, a liner of stone or other suitable material should be installed in that portion of the channel. Remove sediment accumulated behind the dam as needed to allow channel to drain through the check dam and prevent large flows from carrying sediment over the dam. Replace stone, fiber roll, or sand bags as needed to maintain the design cross section of the structures. Rock Check Dams Stone size: Use a well graded matrix of 2 to 9 inch stone X (spacing) = Height of check dam (in feet) Slope in channel (ft/ft) Fiber Rolls Fiber rolls may be used as check dams if they are keyed into the banks, securely fastened in the channel, and the centers are 9 inches lower than the side elevations. Follow the spacing and installation instructions for "Installing Check Dams". Sand Bag Check Dams Sand bags may also be used to form check dams. Follow the installation and spacing instructions in "Installing Check Dams" at the beginning of this section. 9. Winter Requirements Managing construction sites to minimize erosion and prevent sediment loading of waters is a yearround challenge. In Vermont, this challenge becomes even greater during the late fall, winter, and early spring months. 'Winter construction' as discussed here, describes the period between October 15 and April 15, where the erosion prevention and sediment control is significantly more difficult. Rains in late fall, thaws throughout the winter, and spring melt and rains can produce significant flows over frozen and saturated ground, greatly increasing the potential for erosion. At the same time as the erosion risk increases, the “toolbox” available to the planner and on-site plan coordinator shrinks significantly. In particular, establishing vigorous vegetation during winter construction is difficult if not impossible in most areas of the state. How a site addresses winter conditions depends upon the nature of the construction activities over this period. 10 Closing Out Your Construction Project When construction is complete you must finish final grading and stabilize the site. Once the site is stabilized, clean out and remove all temporary sediment controls. Final site stabilization Make sure all subcontractors have repaired their work areas prior to final closeout. Conduct a final inspection of all work areas, vegetation, stormwater flow structures, and downstream receiving waters to make sure no visible gullies or sediment movement is evident. Notify site owner or manager after all temporary erosion and sediment controls have been removed and final stabilization has been completed. If the site is one acre or larger and covered under a VT Storm Water Permit, submit a Notice of Termination to the VT Stormwater Section (see dec.vermont.gov/watershed/stormwater). Vegetated cover considerations for close-out No site is closed out properly until vegetation is established on all bare soil areas and ditches are stable. Check seeded areas, and reseed areas where vegetation is thin or absent. This is especially important for slopes, ditches, and channels. Removing temporary sediment controls When project is completed: Remove all silt fencing and stakes. Grade out and seed or remove accumulated sediment or broadcast over grassed areas or dispose of offsite, where sediment will not impact waters of the State. Culvert inlets should be stabilized, vegetated, and showing no visible gullies. Rock or soil that has been washed away by runoff or upstream flows should be replaced. Brush or other debris that could clog inlets should be removed. Check ditches and channels to make sure banks and ditch bottoms are well vegetated. Reseed bare areas and replace rock that has become dislodged. Check areas where erosion control blankets or matting was installed. Cut away and remove all loose, exposed material, especially in areas where walking or mowing will occur. Reseed all bare soil areas. Replace rock washouts near culvert and channel outlets. Fill, grade, and seed or riprap eroded areas around inlets and outlets. Make sure downstream ditches and channels are fully vegetated. Fill and seed any gullies along the banks or other slopes. Fill in, grade, and seed all temporary sediment traps and basins that have been removed. Double the seeding rate where runoff flows might converge or high velocity flows are expected. Remove temporary stream crossings and grade, seed, or re-plant vegetation removed during crossing installation.

At the same time as the erosion risk increases, the “toolbox” available to the contractor and on-site plan coordinator shrinks significantly over this period (Table 3.4 below). In particular, establishing vigorous vegetation during winter construction is not possible. Based upon the activities anticipated to be undertaken during this period, the Contractor shall plan and implement the following Winter EPSC measures. EPSC Plan Requirements for -Winter Shutdown- For those projects that will complete earth disturbance activities prior to the winter period (October 15), the following must be implemented by the Site Contractor in coordination with the On-Site Plan Coordinator: 1.For areas to be stabilized by vegetation, all seeding shall be completed no later than September 15 to ensure adequate growth and cover. 2.Non-vegetative stabilization of all areas of disturbed soils without existing vegetation shall be completed no later than October 15. 3.When mulch is used as a temporary means of stabilization, the rate of application shall be double that of the regular construction season rate, or roughly 2 inches of mulch with 80-90% cover. Mulch should be tracked in when weather permits or stabilized with netting or an approved tackifier. EPSC Plan Requirements for -Winter Construction- If construction activities involving earth disturbance continue past October 15 or begin before April 15, the following must be implemented by the Owner/Site Contractor: This project is seeking winter (March - April) waiver construction authorization. 1.Enlarged stabilized access points to provide for snow stockpiling. 2.Limits of disturbance flagging moved or replaced to reflect the boundaries of winter work. 3.A snow management plan which implements the following requirements: a.adequate storage and control of snowmelt by diverting these flows around the work area, b.cleared snow is to be stored down gradient of all areas of disturbance c.Storage of snow in stormwater treatment structures is prohibited. d.All drainage structures shall be kept open and free of snow/ice. e.buffer is to be maintained from the perimeter controls such as silt fence to allow for snow clearing and maintenance. f.Install silt fence a minimum of 25 feet down gradient of areas of disturbance and snow storage areas. Reinforce fence in areas where snow load forces may be an issue due to site constrictions. 4.In areas of disturbance within 100 feet of a receiving water, silt fence shall be reinforced or else replaced with perimeter dikes, swales, or other practices resistant to the forces of snow loads. 5.All silt fence and other practices requiring earth disturbance shall be installed ahead of ground freezing. 6.Where mulch is the selected stabilization measure, the mulch shall be installed at double the standard rate of mulch, or roughly 2 inches of mulch with 80-90% cover. 7.Mulch should be tracked in when weather permits or stabilized with netting or an approved tackifier to prevent removal by wind. 8.To ensure cover of disturbed soil in advance of a melt event, areas of disturbed soil must be stabilized at the end of each work day, with the following exceptions: a.If no precipitation within 24 hours is forecast and work will resume in the same disturbed area within 24 hours, daily stabilization is not necessary. b.Disturbed areas that collect and retain runoff, such as house foundations or open utility trenches.” 9.Directions to remove snow or ice to less than 1” thickness prior to temporary or permanent stabilization. 10.Stone stabilization shall be installed a width of 10 to 20ft wide around the perimeter of buildings under construction, where construction vehicle traffic is anticipated. 12/20/2019 DSM DSM MAB 06248 LOCATION MAP 1" = 2000' CEA PROPERTIES, LLC 10 MANSFIELD VIEW LANE SOUTH BURLINGTON VERMONT 05403 CEA CAMPUS PLANNED UNIT DEVELOPMENT LOT 1A MEADOWLAND BUSINESS PARK SOUTH BURLINGTON, VT M E A D O W L A N D D R .KNOLLMILL POND LN.

Coverage under the State Construction General Permit 3-9020 is required for any construction activity that disturbs 1 or more acres of land, or is part of a larger development plan that will disturb 1 or more acres. This project is subject to a moderate risk authorization in coordination with the activities located on lot 1G- Booska Movers This project requires an Individual Permit which is subject to the erosion prevention and sediment control (EPSC) standards set for in the State of Vermont's Standards and Specifications for Erosion Prevention and Sediment Control The following narrative and implementation requirements represent the minimum standard for which this site is required to be maintained as regulated by the State of Vermont. Any best management practices (BMP's) depicted on the project's EPSC Site plan which go beyond the Handbook requirements are considered to be integral to the management of the site and represent components of the municipal EPSC approval for the project which shall be implemented. The EPSC plan depicts one snap shot in time of the site. All construction sites are fluid in their day to day exposures and risks as it relates to minimizing sediment loss from the site. It is the responsibility of the Contractor to implement the necessary BMP's to comply with the Erosion Prevention and Sediment Control Field Guide standards outlined on this sheet based on the interim site disturbance conditions which may or may not be shown on the EPSC Site Plan. This project is authorized to disturb up to 2.3 acres 1. Pre-Construction Planning Planning your construction project can help you avoid costly mistakes in controlling erosion and sediment loss to nearby waterways. Follow the steps below before you begin clearing, grading, and excavation work. If your project is one acre or larger, you will need a construction stormwater permit from the Vermont Department of Environmental Conservation (VT DEC) Stormwater Section (802-828-1535, or see dec.vermont.gov/watershed/stormwater) Assess soils and slopes on the construction site The erosion potential on your construction site depends in part on the soil type and slope steepness at your site. See the table below. Note: there are other factors that contribute to erosion, such as slope length and rainfall intensity and duration. Also, even though there may be low potential for erosion, there can be a high risk to water quality when the soil disturbance is close to water resources Identify nearby streams and drainage control points Walk over the site and find where ditches or other concentrated flows leave the site. These are the final sediment control points. Sediment traps or basins should be installed just above these control points. Your site may drain to an underground storm sewer system. In this case, the storm drain inlets that drain runoff from your site are the control points and must be protected (see Section 7). These are also the compliance points for any permits issued for the site. Install clean water diversions, sediment traps/ basins, grassed ditches, silt check dams, and sediment barriers such as silt fences before clearing and excavation work begins! Preserve existing vegetation wherever possible Only dig or grade where necessary. Existing trees, bushes, and grass help keep erosion to a minimum. Protect large trees by marking off a no-dig root protection zone that is twice as large as the outer perimeter of the branches. Plan your project to limit the amount of bare soil area exposed to the weather, and limit the amount of exposure time. Do not clear vegetation or excavate areas near streams, rivers, lakes, or wetlands without getting the required state and federal permits! Preserve vegetated buffers Preserve existing vegetation near waterways wherever possible. This vegetation is the last barrier to capture sediment runoff before it enters the lake, river, stream, or wetland. Where vegetation has been removed or where it is absent, plant native species of trees, shrubs, and grasses. Design projects to fit the natural topography Minimize clearing and grading to preserve mature vegetation and save money. Identify natural landscape features you want to keep, like large trees, wildflower areas, grasslands, streams, and wetlands. Plan ways to fit your project around these features, so they remain in place after construction is completed. Be sure to mark off these areas with colored ribbon or stakes and warn equipment operators of their location! Minimize impervious surfaces Keep the amount of roof area, parking lots, driveways, and roads to a minimum. Design these hard surfaces so that rain water they collect is directed onto landscaped or yard areas, not into ditches or streams. For example, design roads slightly higher than adjacent lawn areas, and use swales instead of curbs along roadways. Promote infiltration in project design Moving storm water runoff from hard surfaces to landscaped or yard areas helps runoff soak into the soil. This promotes groundwater recharge, filters sediment and other pollutants from runoff, and helps to prevent flooding. Develop an erosion and sediment control plan Develop a written site plan for your project that shows the drainage patterns and slopes, areas of disturbance (cuts/fills, grading), location of erosion and sediment controls, location of surface waters and wetlands, and the location of storm water drainage control points. Your site plan must be updated as conditions change at the site. Design specifications for erosion prevention and sediment control are included in the Vermont Standards and Specifications for Erosion Prevention and Sediment Control. This manual is available for download at: dec.vermont.gov/watershed/stormwater. 2. Construction Phase Operations Divide your construction site into natural drainage areas, so you can deal with each one individually. You will be controlling erosion on bare soil areas by applying seed, mulch, or sediment barriers, and minimizing the time bare soil is exposed to the weather. Control points for sediment in runoff will be at the curb inlets or in the ditches, channels, or sediment traps/basins installed where concentrated flow leaves the site. Install clean water diversions, sediment traps/ basins and stabilize drainage channels with grass, liners, and silt check dams before excavation, fill, or grading work begins (see Section 8). Install silt fences and other sediment barriers downhill from bare soil areas before clearing or excavation work begins (see Section 5). Phase your construction work to minimize exposed soil areas Excavate or place fill material at the site in stages, to avoid exposing large areas of bare soil to the elements. Projects should be cleared and graded as construction progresses. Check your EPSC Plan for your site's permitted disturbance area. Establish final grade quickly, then seed, mulch, or cover bare soil. If work will proceed over several weeks or months, apply temporary seeding or mulch until final grade work is completed. Seed and mulch as soon as possible and as per your permit requirements. Excavation and grading work should be done during dry weather if possible. Prepare for rainy weather by making sure sediment controls are in place and that all exposed areas are mulched. Install construction entrances and control dust Mud tracked onto roads is the number one complaint from citizens regarding construction site operations. Use a matrix of 1 to 4 inch stone for entrance/exit pads leading to roads. Pads should be at least 12 feet wide, 40 feet long, and 8 inches deep. Entrance pads shall not be narrower than the construction entrance. On residential properties, pads may be shorter than 40 feet, as long as they are the length of the driveway. Install filter fabric under the rock to keep it from sinking into the soil below. Rake rock with a grubbing attachment or add new rock if the pad fills with sediment. Control dust during hot, dry weather by seeding or mulching bare areas promptly or by wetting haul roads as needed. Dewatering operations and discharges Water pumped from collection basins or other areas must not be pumped into storm sewers, streams, lakes, or wetlands unless sediment is removed prior to discharge. Discharges to streams, lakes, wetlands, or storm sewers needs to be part of the authorized EPSC Plan. Use sock filters or sediment filter bags on discharge pipes, discharge water into silt fence enclosures installed in vegetated areas away from waterways, or discharge water into a de-silting basin. Remove accumulated sediment after water has dispersed and stabilize or seed the discharge area. Dispose of sediment in areas where it won't wash into waterways, then grade the area and seed. Inspection and maintenance of EPSC practices For sites one acre or larger, the Vermont Construction General Permit requires that you regularly inspect and repair/replace all sedimentation and erosion control measures identified in the EPSC Plan. Discharge locations must also be inspected to ascertain whether erosion control measures are effective in preventing significant impacts to waters of the State. Your inspection reports must be in writing, and kept with your EPSC Plan at the site. Refer to your construction permit for inspection requirements. 3. Diverting Runoff Around Exposed Soils Keep clean runoff from flowing through your construction site, or route it through stable ditches so it won't pick up sediment. Below are some simple, interchangeable approaches for dealing with upland sources of runoff. Earth Dikes An earth dike or berm is a long, mounded “collar” of compacted soil located uphill from the excavated area. The dike is designed to intercept overland runoff and direct it around the construction site. This prevents “clean” water from becoming muddied with soil from the construction site. Earth dikes can be temporary or permanent landscape features of the site. Design Criteria Channel Stabilization Construction Specifications 1. Compact the dike with earth-moving equipment. 2. Stabilize the channel as per the specifications in the table within 48 hours of installation. 3. Top width may be wider and side slopes flatter if desired to facilitate crossing by construction traffic. 4. Ensure the dike has positive drainage to an outlet. 5. Ensure that there is no erosion at the outlet. 6. Runoff shall be conveyed to a sediment trapping device if the dike channel or drainage area above the dike is not adequately stabilized. 7. The earth dike shall remain in place until the disturbed areas are completely stabilized. Diversion Swales Diversion swales are similar to dikes12/20/2019they are designed to intercept and divert upland runoff around bare soil areas. Swales are cut above cleared or fill areas and designed with a gentle slope to carry water away from work areas. Stabilized, lined swales can also be used to move upland water through your site without getting muddy. Construct and line “pass-through” swales before general clearing or grading work begins. Swales should discharge to areas with thick vegetation or flat surfaces to promote dispersal and infiltration. Gullies must be repaired as soon as they appear. Channel Stabilization (see Earth Dike) Construction Specifications 1. Compact the swale with earth-moving equipment. 2. Stabilize the swale as per the specifications for channel stabilization (see Earth Dike). 3. Ensure that the swale has uninterrupted positive drainage to an outlet. 4. Ensure that there is no erosion at the outlet. 5. Diverted runoff from a disturbed area shall be conveyed to a sediment trapping device. 6. All earth removed and not needed for construction shall be stabilized and placed so that it will not interfere with the functioning of the swale. Perimeter Dike and Swale A perimeter dike is a temporary ridge of soil excavated from an adjoining swale located along the perimeter of the site or disturbed area. Design Criteria Drainage area - less than 2 acres Height - 18 inches minimum (measure from bottom of swale to top of dike) Bottom width of dike - 2 feet minimum Width of swale - 2 feet minimum Grade - not to exceed 8%. Swale shall have positive drainage to a stabilized outlet. Construction Specifications 1. Stabilize the dike and swale within 48 hours of installation. 2. Install berm on the contour (along the slope). 3. Diverted runoff from a stabilized upland area shall outlet directly onto an undisturbed, stabilized area at a non-erosive velocity. 4. Diverted runoff from a disturbed upland area shall be conveyed to a sediment trapping device. Water Bar A water bar is a ridge or a ridge and channel constructed diagonally across a sloping road that is subject to erosion. Water bars limit the erosive velocity of water by diverting surface runoff at predesigned intervals. Water Bar Design Criteria Height - 18 inches min height (measure from channel bottom to ridge top) Side Slopes - 2:1 or flatter; 4:1 where vehicles cross Base width of ridge - 6 feet min Grade of water bar - not to exceed 2% Construction Specifications 1. Install the water bar as soon as the road or trail is cleared and graded. 2. Disk or strip the sod from the base for the constructed ridge before placing fill. 3. Track the ridge to compact it to the design cross section. 4. The outlet shall be located on an undisturbed area. Field spacing will be adjusted to use the most stable outlet areas. Outlet protection will be provided when natural areas are not adequate. 5. Vehicle crossing shall be stabilized with gravel. Exposed areas shall be immediately seeded and mulched. 6. Periodically inspect water bars for erosion damage and sediment. Check outlet areas and make repairs as needed to restore operation. 4. Protecting Soils With Seed, Mulch, or Other Products Seeding or covering bare soil with mulch, erosion control matting or blankets, or other products as soon as possible is the cheapest and best way to prevent erosion. Grass seeding alone can reduce erosion by more than 90 percent. The following practices can be used interchangeably for stabilizing exposed soil. Soil cover requirements All areas of disturbance must have temporary or permanent stabilization within 7 days of initial disturbance. After this time, any disturbance in the area must be stabilized at the end of each work day. The following exceptions apply: Stabilization is not required if earthwork is to continue in the area within the next 24 hours and there is no precipitation forecast for the next 24 hours. Stabilization is not required if the work is occurring in a self-contained excavation (i.e. no outlet) with a depth of 2 feet or greater (e.g. house foundation excavation, utility trenches). All areas of disturbance must have permanent stabilization within 48 hours of reaching final grade. NOTE: If the authorization you receive has more protective time limits, then those must be followed. Seed types and application Prepare bare soil for planting by disking across slopes, scarifying, or tilling if soil has been sealed or crusted over by rain. Seedbed must be dry with loose soil to a depth of 12 inches. Soil amendments should be incorporated into the upper 2 inches of soil when feasible. The soil should\ be tested to determine the amounts of amendments needed. Apply ground agricultural limestone to attain a pH of 6.0 in the upper 2 inches of soil. Check seed bag tags to make sure correct seed is used. Mix seed thoroughly prior to loading seeders. Use the following tables to calculate seed application rates and mixture portions. Apply seed by hand, seeder, drill, or hydroseed. Drilled seed should be . inch deep. Mulch seeded areas as soon as possible. Apply more seed to channels, ditches, lawn, and landscaped areas. Apply less seed to areas that are flat or that will not be mowed very often. Water seeded areas during dry conditions to ensure seed germination and early growth. Re-seed areas that do not show growth within 14 days after rain or watering. Protect bare areas during the winter by sowing winter rye at 120 lbs per acre (2.0 lbs/1000 sq. ft.). Seed by September 15 to ensure vegetative cover for winter. Seed mixes for wildflower and native plant plots are also available. They are more expensive, but are very hardy, require little mowing or watering, and add beauty to landscaped and other areas. Most mixes require mowing only once per year, to control tree and brush growth. For slopes steeper than 3:1, walk bulldozer or other tracked vehicle up and down slopes before seeding to create tread-track depressions for catching and holding seed. Mulch slopes after seeding to conserve moisture and provide initial erosion control. Mulch types and application Mulch by itself or applied over seed provides excellent erosion protection (see table). To apply, bring site to final grade and clear rocks, wood, trash, and other debris. Apply seed first. Straw or hay should be hand scattered or blown to obtain a depth of 1 inch (see table). In winter, straw or hay mulch should be applied to obtain a depth of 3 inches. Wood chips or shavings should be applied to a depth of 2 inches. In general, apply mulch so that at least 80 to 90 percent of the ground is covered. *Perform regular maintenance and reapply mulch as needed to ensure bare soil is 80 to 90% covered. Erosion control blankets Erosion control blankets are used to protect steep slopes (up to 3:1; check product information sheets), drainage ditches with less than 20:1 slopes, and other areas where erosion potential is high. Most are designed to provide temporary stabilization until vegetation is established. Blankets degrade within 6 to 24 months, depending on their makeup. They usually consist of a layer of straw, coconut fiber, wood fiber, or jute sandwiched between layers of plastic or fiber mesh. For short slopes (8 feet or less) above channels, install blankets across the slope (horizontal). Install up and down the hill (vertical) for long slopes. Walk blankets down to ensure good contact with the soil. Use plenty of staples to keep blankets flat. Overlap blankets at 6 to 8 inches on sides, tops, and bottoms. Do not stretch blankets, and do not exceed manufacturer's directions on maximum slope angle for the product. Turf reinforcement mats Turf reinforcement mats are similar to erosion control blankets, but are thicker and sturdier because they have more layers and sturdier fill material. Mats provide greater protection than blankets because of their heavier construction, and last longer in the field. Mats are used for steep slopes (3:1 or steeper) and ditches or channels with 15:1 to 10:1 slopes. Mats are installed just like blankets (see previous table). Additional staking or stapling is needed for applications in channels that carry flowing water, and on steep slopes. Sod application Sod reduces the potential for erosion to near zero. To install, bring soil to final grade and clear of trash, wood, rock, and other debris. Test soil, apply topsoil and fertilize in accordance with soil test results. Use sod within 36 hours of cutting. Lay sod in straight lines. Butt joints tightly, but do not overlap joints or stretch sod. Stagger joints in adjacent rows in a brickwork type pattern. Use torn or uneven pieces on the end of the row. Notch into existing grass. On sloping areas where erosion may be a problem, sod shall be laid with the long edges parallel to the contour and with staggered joints. Roll or tamp sod after installation and water immediately. Soak to a depth of 4 to 6 inches. Replace sod that grows poorly. Do not cut or lay sod in extremely wet or cold weather. Do not mow regularly until sod is well established. Bonded Fiber Matrices Other engineered products are available that are similar to blankets and mats. For example, bonded fiber matrices and other hydraulically applied products contain a mix of soil binders, mulch fibers, and even seed and fertilizer that can provide a stable crust that cements soil particles and prevents erosion. Apply seed prior to hydraulic mats or mulches, if seed is not included in the mix. Consult the manufacturer's installation instructions for product applicability and installation instructions. 5. Using Silt Fence and Other Sediment Barriers The use of silt fences and other sediment barriers involves simple observation and common sense. However, as Will Rogers once noted, “common sense ain't so common.” The following practices may be used as interchangeable sediment barriers. Sediment barrier placement Sediment barriers are required below (downhill from) areas of bare soil. Hay or straw bales must not be used as sediment barriers due to their inherent weakness and tendency to fall apart. There are several factors to consider in placing silt fences or perimeter dikes and swales: Place barriers on downhill edge of bare soil areas. Make sure the barrier catches all the runoff. The goal is to intercept runoff and settle sediment out. Install multiple sediment barriers on long slopes. Put barriers across slopes, on the contour (level). Silt Fence Each 100-foot section of silt fence can intercept runoff from about .25 acres. To install a silt fence correctly, follow these steps: Note the location & extent of the bare soil area. Mark silt fence location just below bare soil area or 10 feet below the bottom of a steep slope. Make sure fence will catch all flows from area. Place fence across the slope. Dig trench 6 inches deep and 4 inches wide. Unroll silt fence along trench. Join fencing by rolling the end stakes together. Make sure stakes are on downhill side of fence. Drive stakes in against downhill side of trench. Drive stakes until 16 inches of fabric is in trench. Push fabric into trench; spread along bottom. Fill trench with soil and tamp down. Silt fencing should not be installed: Up and down hills. Above (uphill from) areas of bare soil. In ditches, channels, or streams. In stream buffers. Directly at the toe (bottom) of the slope. Additional storage capacity is needed and can be provided for by placing the fence 10 feet below toe. (Place fence directly at toe if near water or stream buffer) If runoff flows along the uphill side of a silt fence, install “J-hooks” every 40 to 80 feet. These are curved sections of silt fence that act as small dams to stop, pond, and settle out flows. Maximum allowable slope lengths contributing runoff to a silt fence placed on a slope Silt fence slicing devices New tractor-mounted equipment that “slices” silt fence into the ground can provide a better installation than the open trench method. The equipment uses a chisel-point or vibratory plow to create a narrow slit in the ground. Rolled silt fencing is pushed into the slit, creating a very tight seal that prevents water from blowing out the bottom of the fence. Posts are driven and attached to the fence after the fencing is installed. Besides better performance, the slicing method is also faster. For slicing and all other applications, posts are spaced 6 feet apart or less. Perimeter Dike and Swale A perimeter dike is a temporary ridge of soil excavated from an adjoining swale located along the perimeter of the site or disturbed area. The purpose of a perimeter dike and swale is to prevent off site storm runoff from entering a disturbed area and to prevent sediment laden storm runoff from leaving the construction site or disturbed area. Perimeter Dike and Swale Design Criteria Drainage area - less than 2 acres Height - 18 inches minimum (measure from bottom of swale to top of dike) Bottom width of dike - 2 feet minimum Width of swale - 2 feet minimum Grade - not to exceed 8%. Swale shall have positive drainage to a stabilized outlet. Construction Specifications 1. Stabilize the dike and swale within 48 hours of installation. 2. Install berm on the contour (along the slope). 3. Diverted runoff from a stabilized upland area shall outlet directly onto an undisturbed, stabilized area at a non-erosive velocity. 4. Diverted runoff from a disturbed upland area shall be conveyed to a sediment trapping device. 6. Protecting Slopes to Prevent Gullies Slopes12/20/2019especially long ones12/20/2019must be protected to prevent sheet, rill, and gully erosion. Slopes must be stabilized immediately after grading work is completed. The following practices can be used interchangeably to protect and stabilize slopes: The following practices are included in this section for informational purposes only. Consult the EPSC Plan designer or engineer for design and installation specifications. Pipe Slope Drain Subsurface Drain Lined Waterway Engineered Terracing Surface Roughening Retaining Wall Fiber Roll Assessing slopes and soils Steeper slopes (3:1 or steeper) require more protection than flatter slopes. Slopes with highly erodible soils (silty soils) need more protection than those with less erodible soils (sands and gravels). Also, long slopes (greater than 50 feet) are at greater risk for erosion than short slopes. Slope protection basics Protecting slopes from erosion requires several actions that must be taken together. No single approach will be successful, especially if the slope is long, steep, or has highly erodible soils. Use one or more of the following actions to reduce erosion on slopes: Divert upland runoff See Section 3 for information on how to install a berm or channel above the slope to divert upland rain runoff around the bare soil area. Control slope runoff If slopes are broken up into benches or steps, runoff can be collected and diverted along berms or in channels to pipe or open channel slope drains with stable outlets. Till seedbed or condition the soil Dozer tracks up and down slopes help hold soil in place and lengthen the runoff flow path down the slope. See Section 4 for information on how to condition of the soil surface. Seed and mulch The best and cheapest protection by far. See Section 4 for details on seed types, application rates, and mulch, blanket, and mat products. Silt fence or other barrier These should be installed at the toe of the slope or slightly away from the toe. Multiple fences should be installed on long slopes. Fiber rolls installed on the contour work very well in breaking up flows on long slopes. Retaining wall Extremely steep slopes can be leveled out and shortened into two or more steps or benches by installing retaining walls of rock, brick, block, wood, logs, or other material. If rock layers are present along the slope, use these to establish firm benches in a stair-step pattern. Blankets, mats, or armoring Slopes exceeding 3:1 with highly erodible soils must be protected with turf reinforcement mats or other products such as hydraulic soil binders or bonded fiber matrices. Rock mulch and lined downdrain channels might be needed on steep slopes to control gullying. Erosion Control Blankets and Mats Steep slopes can be protected with erosion control mats and blankets. Erosion control matting and blankets are appropriate for slopes up to a 3:1 steepness. For slopes greater than 3:1, use turf reinforcement mats. (See Section 4 for installation details). Hydraulic mulch Bonded fiber matrices and hydraulic mulch can be very effective in controlling erosion on slopes. Hydraulic mulch applied after seeding or with seed in the mix can provide permanent protection if mixed and applied properly. (See Section 4 for details) Rock Gabions Rock Gabions are wire 'baskets' filled with rock used to permanently stabilize slopes. Gabion baskets should be filled with 4 - 8 inch stone and layered according to manufacturers recommendations. Riprap Slope Protection Riprap is a layer of stone designed to protect and stabilize areas subject to erosion. Riprap is used in areas where vegetation cannot be established. Follow your EPSC Plan design specifications for installation. Additional Practices for Protecting Slopes The following practices are included in this section for informational purposes only. Consult the EPSC Plan designer or engineer for design and installation specifications. Pipe Slope Drain A pipe slope drain is a temporary structure placed from the top to the bottom of a slope to convey runoff down the slope without causing erosion. Subsurface Drain A subsurface drain is a conduit, such as a tile, pipe, or tubing installed beneath the ground surface that intercepts, collects, and/or conveys drainage water. Stone Lined Waterway A stone lined waterway is a channel that carries water down a slope to prevent slope erosion or gullying. Engineered Terracing Terracing is the reshaping of the existing land surface to control erosion and promote the establishment of vegetation. Surface Roughening Roughening bare soil by creating horizontal grooves across a slope, stair-stepping, or tracking with construction equipment aids in seed establishment, reduces runoff velocity, increases infiltration, and reduces erosion by trapping water and sediment. Retaining Wall A retaining wall is constructed against a slope to prevent soil movement. It retains soil in place and prevents slope failures and movement of material down steep slopes. Retaining walls can be built from mortared block or stone, cast-in-place concrete, railroad ties, gabions, and precast, modular, segmented walls. The design of any retaining wall structure must address the aspects of foundation bearing capacity, sliding, overturning, drainage, and loading systems. These are complex systems and all but the smallest retaining walls should be designed by a licensed engineer. Fiber Roll A fiber roll is a woven roll of coconut fiber, straw, or excelsior encased in a netting of jute, nylon, or burlap. Fiber rolls can be used to break up runoff flows on long slopes. 7. Protecting Culvert and Ditch Inlets and Outlets Culverts and ditches are designed to carry moderate and large flows of storm water. They can transport a lot of sediment to streams, rivers, wetlands, and lakes if they are not properly protected. In addition, culvert and ditch outlets can become severely eroded if high velocity flows are not controlled. Culvert and storm drain ponding methods Muddy runoff that flows toward a culvert, ditch, or storm drain inlet must be slowed down and pooled to settle out and remove sediment. This can be accomplished by placing rock, reinforced silt fencing, silt dikes, or other barrier in front of the inlet. The goal is to cause ponding of the inflow so sediment can settle out, and allow ponded water to enter the inlet only after sediment has been removed. Straw bales alone are not approved for inlet protection. The maximum drainage area above the inlet protection device is one acre. For all inlet protection approaches, seeding and/or mulching upland areas promptly will greatly reduce incoming runoff volumes and sediment loads. The drainage area for storm drain inlets shall not exceed one acre. All inlet protection practices should be inspected after storm events and repaired as necessary. Accumulated sediment should be removed when 50% of ponding volume is lost. The following are interchangeable practices for inlet protection: Excavated drop inlet protection Side slopes - maximum steepness 2:1 Depth - minimum 1 foot; maximum 2 feet Shape the excavated basin to fit conditions with the longest dimension oriented toward the longest inflow area to provide maximum trap efficiency. The capacity of the excavated basin, below the level of the grate, should be established to contain 900 cubic feet per acre of disturbed area. Weep holes, protected by fabric and stone, should be provided for draining the temporary pool. Inspect and clean the excavated basin after every storm. Sediment should be removed when 50 percent of the storage volume is lost. Filter fabric drop inlet protection Slope around device - Not to exceed 1% Height of fabric - 1.5 feet max., (unless reinforced). The top of the barrier should be maintained to allow overflow to drop into the drop inlet and not bypass the inlet to unprotected lower areas. Support stakes - 3 feet min., spaced max 3 feet apart; Stakes should be driven close to the inlet so overflow drops into the inlet and not on the unprotected soil. 1. Filter fabric shall have an equivalent opening size (EOS) of 40-85. 2. Cut fabric from a continuous roll to eliminate joints. 3. Stakes will be standard 2 x 4 inch wood or metal with a minimum length of 3 feet. 4. Space stakes evenly around inlet, 3 feet apart and 18 inches deep. Spans greater than 3 feet should be reinforced with wire mesh. 5. Fabric shall be embedded at least 1 foot in ground and backfilled. It should be secured to the stakes. 6. A 2 x 4 inch wood frame shall be completed around the crest of the fabric for overflow stability. Stone and block drop inlet protection Height - 1 foot min., 2 feet max. Limit the height to prevent excess ponding and bypass flow. Block placement - Recess the first row of blocks at least 2 inches below the top of the storm drain for lateral support. Blocks can also be supported by placing a 2x4 inch wood stud through the block openings perpendicular to the row. The bottom row should have a few blocks oriented so flow can drain through the block to dewater the basin area. Stone placement - Place stone just below the top of the blocks on slopes of 2:1 or flatter. Place hardware cloth of wire mesh with . inch openings over all block openings to hold stone in place. Optional "doughnut" design - The concrete blocks may be omitted and the entire structure constructed of stone, ringing the outlet. The stone should be kept at a 3:1 slope toward the inlet to keep it from being washed into the inlet. A level area 1 foot wide and four inches below the crest will further prevent wash. Stone size for "doughnut" - At least 3 inches closest to the inlet, for stability; 1 inch or smaller around the larger rock to control flow rate. Elevation for "doughnut" - The top of the stone should be 6 inches lower than the ground elevation down slope from the inlet to ensure that all storm flows pass over the stone into the storm drain and not past the structure. Temporary diking should be used as necessary to prevent bypass flow. Curb drop inlet protection Stone size - 2 inches Wire mesh - of sufficient strength to support the filter fabric and stone with the water fully impounded against it. Filter fabric - type approved for this purpose with an equivalent opening size (EOS) of 40-85. Length of structure - must extend beyond the inlet 2 feet in both directions. Assure that storm flow does not bypass the inlet by installing temporary dikes (such as sand bags) directing flow into the inlet. Make sure that the overflow weir is stable. Traffic safety shall be integrated with the use of this practice. The structure should be inspected after every storm event. Any sediment should be removed and disposed of on the site. Any stone missing should be replaced. Check materials for proper anchorage and secure as necessary. Outlet protection methods Outlets for storm drains, culverts, and paved channels that discharge into natural or constructed channels must be lined with rock or other armoring to prevent downstream bank and channel erosion when flow velocities are high. The following practices are included in this section for informational purposes only. Consult the EPSC Plan designer or engineer for design and installation specifications. Rock Outlet Protection Paved Flume Level Spreader Rock outlet protection Rock placed at the end of culvert reduces the depth, velocity, and energy of water, such that the flow will not erode the receiving downstream reach. Paved Flume A paved flume is a small concrete-lined channel designed to convey concentrated runoff safely down the face of a relatively steep slope without causing erosion.

Stabilizing Drainage Ditches Stabilizing drainage ditches helps to provide for the safe transport of excess surface water from the construction sites and urban areas without damage from erosion. This section is divided into 3 parts: Vegetating Low Grade Channels, Protecting Steep Channels, and Installing Check Dams Interchangeable practices are provided for Vegetating Channels and Installing Check Dams. Practices for Protecting Steep Channels are included in this section for informational purposes only. Consult the EPSC Plan designer or engineer for design and installation specifications for steep channel protection. Vegetating Low Grade Channels Vegetating drainage channels helps to reduce the velocity of the channelized runoff and limit the erosion potential. The following practices can be used interchangeably to vegetate low grade channels. Seed and Mulch To establish vegetation in a channel, seed and mulch using the guidance in Section 4. Prepare the soil for seeding and ensure that vegetation is well established before water is diverted to the channel. SECTION Rolled Erosion Control Products (RECPs) Rolled Erosion Control Products (RECPs) include erosion control mats, turf reinforcement mats, and jute and excelsior matting. RECPs should be used in channels with flow velocities up to 3.5 feet/sec. See Section 4 for installation instructions and seeding information. Sodding Sod can also be used in low grade channels to reduce runoff velocities and minimize erosion potential. See Section 4 for sod installation instructions and specifications. Protecting Steep Channels Channels with grades steeper than 3:1 may need additional armoring to prevent downcutting and erosion. The following practices are included in this section for informational purposes only. Consult the EPSC Plan designer or engineer for design and installation specifications. Rock Lining Grade Stabilization Structure Rock Lining Riprap lined channels provide for the transport of concentrated runoff without damage from erosion, where vegetated channels would be inadequate due to high velocities. Grade Stabilization Structure Grade stabilization structures control head cutting in natural or man made channels. They are designed to limit erosion by reducing velocities and grade in the watercourse. Installing Check Dams Drainage ditches need temporary check dams to capture sediment and reduce ditch bottom downcutting. The following are interchangeable types of check dams. Silt fencing and hay bales are not approved for use as check dams, and must not be used in drainage ditches that carry flowing water. Also, do not place dams in creeks or streams. Sediment must be intercepted before it reaches streams, lakes, or wetlands. Design Criteria Drainage Area: Maximum 2 acres Height: No greater than 2 feet. Center of dam should be 9 inches lower than the side elevation Side slopes: 2:1 or flatter Spacing: Space the dams so that the bottom (toe) of the upstream dam is at the elevation of the top (crest) of the downstream dam. This spacing is equal to the height of the check dam divided by the channel slope. Spacing (in feet) = Height of check dam (in feet) Slope in channel (ft/ft) Check dams should be anchored in the channel by a cutoff trench 1.5 feet wide and 0.5 feet deep and lined with filter fabric to prevent soil migration. Maintenance: Check dams should be inspected after each runoff event. Correct all damage immediately. If significant erosion has occurred between structures, a liner of stone or other suitable material should be installed in that portion of the channel. Remove sediment accumulated behind the dam as needed to allow channel to drain through the check dam and prevent large flows from carrying sediment over the dam. Replace stone, fiber roll, or sand bags as needed to maintain the design cross section of the structures. Rock Check Dams Stone size: Use a well graded matrix of 2 to 9 inch stone X (spacing) = Height of check dam (in feet) Slope in channel (ft/ft) Fiber Rolls Fiber rolls may be used as check dams if they are keyed into the banks, securely fastened in the channel, and the centers are 9 inches lower than the side elevations. Follow the spacing and installation instructions for "Installing Check Dams". Sand Bag Check Dams Sand bags may also be used to form check dams. Follow the installation and spacing instructions in "Installing Check Dams" at the beginning of this section. 9. Winter Requirements Managing construction sites to minimize erosion and prevent sediment loading of waters is a yearround challenge. In Vermont, this challenge becomes even greater during the late fall, winter, and early spring months. 'Winter construction' as discussed here, describes the period between October 15 and April 15, where the erosion prevention and sediment control is significantly more difficult. Rains in late fall, thaws throughout the winter, and spring melt and rains can produce significant flows over frozen and saturated ground, greatly increasing the potential for erosion. At the same time as the erosion risk increases, the “toolbox” available to the planner and on-site plan coordinator shrinks significantly. In particular, establishing vigorous vegetation during winter construction is difficult if not impossible in most areas of the state. How a site addresses winter conditions depends upon the nature of the construction activities over this period. 10 Closing Out Your Construction Project When construction is complete you must finish final grading and stabilize the site. Once the site is stabilized, clean out and remove all temporary sediment controls. Final site stabilization Make sure all subcontractors have repaired their work areas prior to final closeout. Conduct a final inspection of all work areas, vegetation, stormwater flow structures, and downstream receiving waters to make sure no visible gullies or sediment movement is evident. Notify site owner or manager after all temporary erosion and sediment controls have been removed and final stabilization has been completed. If the site is one acre or larger and covered under a VT Storm Water Permit, submit a Notice of Termination to the VT Stormwater Section (see dec.vermont.gov/watershed/stormwater). Vegetated cover considerations for close-out No site is closed out properly until vegetation is established on all bare soil areas and ditches are stable. Check seeded areas, and reseed areas where vegetation is thin or absent. This is especially important for slopes, ditches, and channels. Removing temporary sediment controls When project is completed: Remove all silt fencing and stakes. Grade out and seed or remove accumulated sediment or broadcast over grassed areas or dispose of offsite, where sediment will not impact waters of the State. Culvert inlets should be stabilized, vegetated, and showing no visible gullies. Rock or soil that has been washed away by runoff or upstream flows should be replaced. Brush or other debris that could clog inlets should be removed. Check ditches and channels to make sure banks and ditch bottoms are well vegetated. Reseed bare areas and replace rock that has become dislodged. Check areas where erosion control blankets or matting was installed. Cut away and remove all loose, exposed material, especially in areas where walking or mowing will occur. Reseed all bare soil areas. Replace rock washouts near culvert and channel outlets. Fill, grade, and seed or riprap eroded areas around inlets and outlets. Make sure downstream ditches and channels are fully vegetated. Fill and seed any gullies along the banks or other slopes. Fill in, grade, and seed all temporary sediment traps and basins that have been removed. Double the seeding rate where runoff flows might converge or high velocity flows are expected. Remove temporary stream crossings and grade, seed, or re-plant vegetation removed during crossing installation.

At the same time as the erosion risk increases, the “toolbox” available to the contractor and on-site plan coordinator shrinks significantly over this period (Table 3.4 below). In particular, establishing vigorous vegetation during winter construction is not possible. Based upon the activities anticipated to be undertaken during this period, the Contractor shall plan and implement the following Winter EPSC measures. EPSC Plan Requirements for -Winter Shutdown- For those projects that will complete earth disturbance activities prior to the winter period (October 15), the following must be implemented by the Site Contractor in coordination with the On-Site Plan Coordinator: 1.For areas to be stabilized by vegetation, all seeding shall be completed no later than September 15 to ensure adequate growth and cover. 2.Non-vegetative stabilization of all areas of disturbed soils without existing vegetation shall be completed no later than October 15. 3.When mulch is used as a temporary means of stabilization, the rate of application shall be double that of the regular construction season rate, or roughly 2 inches of mulch with 80-90% cover. Mulch should be tracked in when weather permits or stabilized with netting or an approved tackifier. EPSC Plan Requirements for -Winter Construction- If construction activities involving earth disturbance continue past October 15 or begin before April 15, the following must be implemented by the Owner/Site Contractor: This project is seeking winter (March - April) waiver construction authorization. 1.Enlarged stabilized access points to provide for snow stockpiling. 2.Limits of disturbance flagging moved or replaced to reflect the boundaries of winter work. 3.A snow management plan which implements the following requirements: a.adequate storage and control of snowmelt by diverting these flows around the work area, b.cleared snow is to be stored down gradient of all areas of disturbance c.Storage of snow in stormwater treatment structures is prohibited. d.All drainage structures shall be kept open and free of snow/ice. e.buffer is to be maintained from the perimeter controls such as silt fence to allow for snow clearing and maintenance. f.Install silt fence a minimum of 25 feet down gradient of areas of disturbance and snow storage areas. Reinforce fence in areas where snow load forces may be an issue due to site constrictions. 4.In areas of disturbance within 100 feet of a receiving water, silt fence shall be reinforced or else replaced with perimeter dikes, swales, or other practices resistant to the forces of snow loads. 5.All silt fence and other practices requiring earth disturbance shall be installed ahead of ground freezing. 6.Where mulch is the selected stabilization measure, the mulch shall be installed at double the standard rate of mulch, or roughly 2 inches of mulch with 80-90% cover. 7.Mulch should be tracked in when weather permits or stabilized with netting or an approved tackifier to prevent removal by wind. 8.To ensure cover of disturbed soil in advance of a melt event, areas of disturbed soil must be stabilized at the end of each work day, with the following exceptions: a.If no precipitation within 24 hours is forecast and work will resume in the same disturbed area within 24 hours, daily stabilization is not necessary. b.Disturbed areas that collect and retain runoff, such as house foundations or open utility trenches.” 9.Directions to remove snow or ice to less than 1” thickness prior to temporary or permanent stabilization. 10.Stone stabilization shall be installed a width of 10 to 20ft wide around the perimeter of buildings under construction, where construction vehicle traffic is anticipated. 12/20/2019 DSM DSM MAB 06248 LOCATION MAP 1" = 2000' CEA PROPERTIES, LLC 10 MANSFIELD VIEW LANE SOUTH BURLINGTON VERMONT 05403 CEA CAMPUS PLANNED UNIT DEVELOPMENT LOT 1A MEADOWLAND BUSINESS PARK SOUTH BURLINGTON, VT M E A D O W L A N D D R .KNOLLMILL POND LN.
