Box 752 Lake George,NY 12845 1.3 PLANS AND REPORTS Plans and additional reports to be used in conjunction with this Stormwater Pollution Prevention Plan(SWPPP) are as follows: ■ Plans entitled "Corinth Road U-Store It 2, 398 Corinth Road", prepared by ABD Engineers, LLP, dated June 15, 2018. ■ Stonnwater Management Report for"Corinth Road U-Store It 2, 398 Corinth Road"prepared by ABD Engineers, LLP, 411 Union Street, Schenectady, NY 12305, dated June 15, 2018. 1.4 DESCRIPTION: (PURPOSE AND TYPES OF SOIL DISTURBING ACTIVITIES) The Owner/Applicant is proposing to develop an 8.6±acre parcel located at 398 Corinth Road in the town of Queensbury, Warren County,New York(see Exhibit 1). The site is bordered on the west by commercial property, on the south by Corinth Road, on the east by residential houses, and on the north by woods. The Owner/Applicant is proposing to construct 12 self storage buildings, associated pavement, and stonnwater management areas. ABD Engineers,LLP 3 Corinth Road U-Store It 2 5010A-SWPPP 398 Corinth Road According to the Warren County NRCS, the primary hydrologic soil group is type A, loamy fine sand. The existing site drains to low points onsite and infiltrates. Soil disturbing activities include cuts and fills to produce suitable grades for construction of the referenced components. Installation of utilities will require trench excavation and backfilling. 1.5 STORMWATER MANAGEMENT See Stormwater Management Report. 1.5A STORMWATER MANAGEMENT&PLANNING PER CHAPTER 3&4 OF THE NYSDEC STORMWATER MANAGEMENT DESIGN MANUAL AUGUST 2015 a. Site planning to preserve natural features and reduce impervious cover; The development is mainly limited to the flatter and non-wooded areas. Impervious surfaces included in the proposed project are rooftops of buildings,roads, and parking. Infiltration is used to recharge the groundwater as in the pre-development condition. b. Calculation of the Water Quality Volume for the Site; The water quality volume calculation has been provided in the referenced stormwater management report and meets NYSDEC stormwater regulations. The water quality volume has been provided based on RRV due to the soils and topography of the site. The onsite soil type is sandy Type A, which allows for the use of infiltration practices. c. Incorporation of Green Infrastructure Techniques and Standard SMP's with Runoff Reduction Volume (RRv) Capacity; Stormwater from the developed area will be treated through the use of infiltration and meets WQv and RRV requirements. The design utilizes infiltration basins which will detain and treat runoff from a 100-year storm. d. Design of Volume and Peak Rate Control Practices; Though not required, this project meets or exceeds NYSDEC stormwater regulations. Calculations and further discussions are attached to the stonnwater management report prepared for this project. Stormwater draining to the infiltration basins will be treated and will infiltrate. ABD Engineers,LLP 4 Corinth Road U-Store It 2 5010A-SWPPP 398 Corinth Road 1.6 SEQUENCE OF MAJOR ACTIVITIES The following is the general sequence of construction that will occur on the site. 1.61 Site Preparation. Silt fence will be installed all along the descending slopes of the limits of grading and at any other location where siltation may occur. The silt fence shall remain in place until all areas being served are stabilized. A temporary construction entrance shall be established to capture mud and debris from construction vehicles before they enter public roads. Clearing and earth disturbance shall be limited to that necessary to install temporary sediment control measures. 1.62 Rough Grading. Trees and other vegetation will be removed from areas to be disturbed. Some topsoil stripping and stockpiling will take place to be used later in landscaped areas. Earthmoving to grade the site to approved finish grades may then occur. Any additional required silt fence will be installed. There shall not be more than five (5) acres of disturbed soil at any one time without prior written approval from the Department of Environmental Conservation. 1.63 Building Site Preparation. The location of the buildings will be graded to establish the finished floor elevation. The construction of the buildings will occur concurrently with the remaining site work. 1.64 Utility Installation. Utilities and drainage facilities will be installed once subgrades are established and fills are compacted. 1.65 Paving. Ingress/Egress driveways and parking will be paved. 1.66 Landscaping. Topsoil will be spread on areas to be landscaped and areas will be planted/seeded in accordance with the plans. All disturbed areas must be stabilized. In areas where soil disturbance activity has temporarily or permanently ceased, the application of soil stabilization measures must be initiated by the end of the next business day and completed within fourteen(14) days from the date the current soil disturbance activity ceased. 1.7 NAME OF RECEIVING WATERS The nearest surface body of water is the Clendon Brook. Stormwater from the proposed site infiltrates and recharges groundwater with no offsite discharge. ABD Engineers,LLP 5 Corinth Road U-Store It 2 501OA-SWPPP 398 Corinth Road 2.0 CONTROLS 2.1 EROSION AND SEDIMENT CONTROLS. STABILIZATION PRACTICES. Disturbed areas within the limits of grading will be stabilized by planting/seeding and mulching. Where seeding stabilization is needed, perennial rye grass applied at a rate of 150 pounds per acre may be used. All seeded areas are then to be mulched using straw mulch at a rate of 2 ton per acre. If anchoring of the straw mulch is needed, wood fiber inulch may then be applied at a rate of 500 pounds per acre. 2.2 STRUCTURAL PRACTICES. Silt fence or straw bale dikes will be placed on the downhill side of exposed slopes and trenches before clearing or excavation take place. The silt fence shall be Amoco 1380 geotextile fabric, or equal, attached to 2"x2"minimum wooden stakes as per manufacturer's recommendations as shown on the"Erosion and Sediment Control Details". It shall remain and be inspected and maintained until the site is stabilized. Maintenance shall be performed as needed, and sediment material removed when"bulges" develop in the silt fence. Inspections of the straw bale dikes shall be frequent, and repair replacements shall be made promptly as needed. Silt barriers will also be installed in the flow line of drainage channels and ditches. Erosion control barriers will be supplemented as necessary during construction and will be maintained throughout the duration of site construction activity by the Contractor. Runoff will be directed away from excavated areas, and temporary swales will be installed with a minimum grade of one percent. Stabilization shall occur as soon as practicable. Watering of excavation and fill areas to minimize wind erosion during construction should be accomplished as required. Stabilization should be completed as soon as practicable for the surface of all perimeter controls and pennanent slopes. Following initial soil disturbance of any kind, stabilization should be completed within 14 days or as soon as possible. At any location where surface runoff from disturbed or graded areas may flow off the construction area, temporary sediment control measures must be installed to prevent sediment from traveling off site. No grading, filling, or other disturbance is allowed within existing drainage swales. At the end of each workday during earthwork, operators shall grade all areas to temporary detention basin(s). Temporary and permanent detention basins shall be dewatered after all rainfall events if captured water does not infiltrate within 24 hours after the end of rainfall. Basins should be ABD Engineers,LLP 6 Corinth Road U-Store It 2 5010A-SWPPP 398 Corinth Road dewatered to sediment bags located in relatively level areas, preferably undisturbed areas of native vegetation. At no time shall a basin be dewatered directly to a stream or wetland. A qualified inspector will inspect all erosion control measures employed during construction activities to measure proper performance and correct immediately as needed. In areas where construction would take place in"wet soils", curtain drains or subsurface drainage will be installed to de-water the soils. Construction vehicle traffic will be directed so as to avoid steep slopes and areas to remain vegetated to the maximum extent practicable. The Contractor will be held responsible for any soil exposure and/or erosion that occurs outside the defined limits of work and haul roads, and will . immediately install erosion control measures and stabilize disturbed areas. Furthermore, any fines that could arise as a result of improper implementation of this Stormwater Pollution Prevention Plan (SWPPP) will be the responsibility of the Contractor. Only the owner or his designated representative will have the authority to authorize Contractor- requested disturbance beyond the limits on these plans. Any applicant- authorized changes will require signatory certification using the form in this Stormwater Pollution Prevention Plan. To prevent sediment-laden water from entering the storm drain system through the inlets, all catch basins will be protected by the "fabric barrier drop inlet protection"practice until the drainage areas served by these catch basins are stabilized. The fabric barrier shall be inspected after each rain event and repairs made as needed. Sediment shall be removed as necessary and disposed of properly. Sandbag trench plugs will be placed in sloping open trenches during installation of utilities. Locate temporary topsoil stockpiles in areas, which do not receive direct runoff from swales or streams. The temporary topsoil stockpiles shall be protected with diversion swales if necessary. Locate temporary topsoil stockpile areas beyond proposed grading activities. To minimize erosion potential, enclose temporary topsoil stockpile areas with silt fencing. Seed temporary topsoil stockpile areas to reduce erosion if stored for prolonged periods. ABD Engineers,LLP 7 Corinth Road U-Store It 2 5010A-SWPPP 398 Corinth Road All silt or sediment accumulations will be cleaned from stormwater quality management basins. All temporary and permanent detention and sediment basins, and all drainage swales will be kept free of debris and litter, and the vegetation should be maintained to allow unobstructed flow of stormwater. Any slopes or embankinents, which have damaged vegetation,will be reseeded as necessary. All grass swale areas will be snowed so as to facilitate unobstructed flow of stormwater. 2.3 OTHER CONTROLS 2.31 Waste Disposal 2.311 Waste Materials: All waste materials generated during site preparation and construction will be disposed of at a suitable landfill, transfer station or C &D landfill. The contractors shall inspect for and have litter picked up on a daily basis. 2.312 Hazardous Waste The project will not be a generator of hazardous waste and it is not anticipated that any hazardous waste will be generated during construction. If there are any materials generated, a licensed hazardous waste carrier will be contracted to dispose of the hazardous material at a suitable disposal site. If hazardous materials are discovered during construction, the work will be stopped until the issue is resolved. 2.313 Sanitary Waste Portable sanitary facilities will be made available to construction personnel and will be serviced regularly. 2.32 Offsite Vehicle Tracking. Earthwork equipment involved with the construction will remain on the project site and will not regularly egress or ingress the site. Any trucks used to bring in materials or remove materials will do so over a stabilized construction entrance so as to capture mud and debris before they enter the public highway. The stabilized construction entrance ABD Engineers,LLP 8 Corinth Road U-Store It 2 5010A-SWPPP 398 Corinth Road shall be 50 feet minimum in length by 24 feet minimum in width. Typar 3401, or equal, filter cloth will be placed over the entire area prior to the placement of 6 inches of 2" stone. The entrance shall be maintained in a condition that will prevent tracking, or flowing of sediment onto public rights- of-way. This may require periodic top dressing with additional stone as conditions demand. Periodic inspection and needed maintenance shall be provided after each rain. If significant off-site vehicle tracking begins to occur, the contractor will be directed to institute a regular street sweeping program in the vicinity of the site. 3.0 TIMING OF CONTROLS/MEASURES Prior to commencement of construction activity, Owner or operator must identify the contractor(s) and subcontractor(s) that will be responsible for installing, constructing, repairing, replacing, inspecting and maintaining the erosion and sediment control practices within this SWPPP. Temporary structural erosion controls will be installed prior to earthwork as per the aforementioned plans. The Owner shall have a qualified inspector conduct an assessment of the site prior to the commencement of construction, and be aware of appropriate erosion and sediment controls described in this SWPPP have been adequately installed or implemented to ensure overall preparedness of the site for the commencement of construction. To prevent sediment-laden water from entering the storm drain system through the inlets, all catch basins will be protected by the "fabric barrier drop inlet protection"practice until the drainage areas served by these catch basins are stabilized. The fabric barrier shall be inspected after each rain event and repairs made as needed. Sediment shall be removed as necessary and disposed of properly. All temporary sediment basins shall be pumped out within 24 hours of the end of all rainfall events if stormwater has not drained or infiltrated. Temporary erosion control devices will not be removed until the growth of vegetation or other erosion control measures stabilizes the area served. In areas where soil disturbance activity has temporarily or permanently ceased, the application of soil stabilization measures must be initiated by the end of the next business day and completed within fourteen (14) days from the date the current soil disturbance activity ceased. ABD Engineers,LLP 9 Corinth Road U-Store It 2 501OA-SWPPP 398 Corinth Road The Owner and Contractor shall retain copies of the Stormwater Pollution Prevention Plan, all reports, and data for a minimum of five years following final stabilization of the site. During construction of the project, all inspection, maintenance, and repair procedures as stated in this Stormwater Pollution Prevention Plan are the ultimate responsibility of The Owner, his heirs or assigns. All temporary measures that were installed in accordance with this Stormwater Pollution Prevention Plan shall remain the ultimate responsibility of The Owner, his heirs or assigns until such time as all areas being served are stabilized. Only after this stabilization occurs may these temporary measures be removed. A site can be considered finally stabilized when all soil disturbing activities have been completed and a uniformm perennial vegetative cover with a density of 80% for the unpaved areas and areas not covered by permanent structures has been established or equivalent pennanent stabilization measures have been established, and the facility no longer discharges stormwater associated with construction activities, and approved by the engineer. The long term post-construction inspection, maintenance, and repair procedures as stated in this Stormwater Pollution Prevention Plan will be performed by the Owner,his heirs or assigns. The Owner, his heirs or assigns will have the ultimate responsibility of the long- term maintenance, and repair procedures for all of the entire stormwater system as shown on the plans. An operations and maintenance manual for the Stormwater Management Control Practices will be given to The Owner, his heirs or assigns, which will include the inspection checklist from the"New York State Stormwater Management Design Manual." 4.0 CERTIFICATION OF COMPLIANCE WITH FEDERAL, STATE AND LOCAL REGULATIONS There will be no offsite discharge to the waters of the United States and/or municipal stormwater systems and a Notice of Intent is not required. However, the standard methods for Erosion and Sediment Control do still apply as shown on the site plans. 5.0 MAINTENANCE/INSPECTION PROCEDURES 5.1 EROSION AND SEDIMENT CONTROL INSPECTION AND MAINTENANCE PRACTICES These are the inspections and maintenance practices that will be used to maintain erosion and sediment controls: ABD Engineers,LLP 10 Corinth Road U-Store It 2 5010A-SWPPP 398 Corinth Road ■ A trained individual, appointed by the Contractor's construction manager, will supervise day to day activities on the site during soil disturbing activities. ■ All measures will be maintained in good working order and be fully operational. If repair is necessary, it will be initiated within 24 hours of discovery. ■ A qualified contractor must look for evidence of the soil erosion on the site,potential of pollutants entering drainage systems,problems at discharge points (such as turbidity in receiving water), and signs of soil and mud transport from the site to the public road at the entrance. ■ Silt fence maintenance shall be performed as needed, and sediment material removed when "bulges" develop in the silt fence. ■ Built up sediment will be removed from silt fence and straw bales if it ever reaches one-third the height of the structural control. ■ Silt fence will be inspected for depth of sediment, tears, to see if the fabric is securely attached to the fence posts, and to see that the fence posts are firmly in the ground. ■ All temporary sediment basins should be inspected for stability and integrity once a week and after any storm event. Any structural failure in sediment basins or trenches that serve them will be repaired within 24 hours after detection. ■ All temporary sediment basins shall be pumped dry after all rainfall events that cause water to accumulate in the basins. Basins shall be dewatered to an undisturbed upland area or to a sediment bag or trap. ■ All temporary sediment basins shall be cleaned out when one half the design depth of the basin has accumulated. All spoils shall be removed to a stabilized upland area. ■ The"fabric barrier drop inlet protection", put in at all catch basins to keep sediment from entering the storm drain system, shall be inspected after each rain event and repairs made as needed. Sediment shall be removed as necessary and disposed of properly. ■ Stabilized construction entrance inspection and needed maintenance shall be provided after each rain. ■ The trained individual shall inspect for and have litter picked up on a daily basis. ■ Where seeding stabilization is needed,perennial ryegrass applied at a rate of 150 pounds per acre may be used. All seeded areas are then to be mulched using straw mulch at a rate of 2 ton per acre. If anchoring of the straw mulch is needed, wood fiber mulch may then be applied at a rate of 500 pounds per acre. ABD Engineers,LLP 11 Corinth Road U-Store It 2 5010A-SWPPP 398 Corinth Road ■ Seeded and planted areas will be inspected for bare spots, washouts and healthy growth. If necessary, replanting,reseeding or sodding will be implemented. 5.2 NON-STORMWATER DISCHARGES Any water collected in excavated areas will be pumped to a sediment bag located in an upland area or a sediment basin. All temporary sediment basins will be dewatered to sediment bags. Once the material is dewatered, sediment will be removed to an upland area. 6.0 INVENTORY FOR POLLUTION PREVENTION PLAN: SPILL PREVENTION 6.1 MATERIAL MANAGEMENT PRACTICES The following are the material management practices that will be used to reduce the risk of spills or other accidental exposure of materials and substances to storm water runoff. 6.11 Good Housekeeping The following good housekeeping practices will be followed onsite during the construction project: ■ An effort will be made to store only enough product required to do the job. ■ All materials stored onsite will be stored in a neat, orderly manner in their appropriate containers, and if possible, under a roof or other enclosure. ■ Products will be kept in their original containers with the original manufacturer's label. ■ Substances will not be mixed with one another unless recommended by the manufacturer, ■ Whenever possible, all of a product will be used up before disposal. ■ Manufacturer's recommendations for proper use and disposal will be followed. ■ The trained individual will inspect daily to ensure proper use and disposal of materials onsite. ■ The contractor shall prohibit washing of tools, equipment and machinery in or within 100 feet of any watercourse or wetland and install sediment traps to filter runoff from washing operations that could enter any watercourse. ABD Engineers,LLP 12 Corinth Road U-Store It 2 5010A-SWPPP 398 Corinth Road 6.12 Hazardous Products These practices are used to reduce the risks associated with hazardous materials: ■ Products will be kept in original containers unless they are not resealable. ■ Original labels and material safety data sheets will be retained; they contain important product inforination. ■ If surplus product must be disposed of, manufacturers' or local and State recommended methods for proper disposal will be followed. 6.2 PRODUCT SPECIFIC PRACTICES The following product specific practices will be followed onsite: 6.21 Petroleum Products ■ Construction personnel should be made aware that emergency telephone numbers are located in this SWPPP ■ The contractor shall immediately contact NYSDEC in the event of a spill, and shall take all appropriate steps to contain the spill including constructing a dike around the spill and placing absorbent material over this spill. ■ The contractor shall instruct personnel that spillage of fuels, oils, and similar chemicals must be avoided. ■ Fuels, oils and chemicals will be stored in appropriate and tightly capped containers. Containers shall not be disposed of on the project site. ■ Store fuels, oils, chemicals, material and equipment and locate sanitary facilities away from trees and at least 100 feet from streams, wells, wet areas, and other enviromnentally sensitive sites. ■ Dispose of chemical containers and surplus chemicals off the project site in accordance with label directions. ■ Use tight connections and hoses with appropriate nozzles in all operations involving fuels, lubricating materials or chemicals. ■ Use funnels when pouring fuels, lubricating materials or chemicals. ■ Refueling and cleaning of construction equipment will take place from access roads, in staging areas along roadside areas whenever practical to provide rapid response to emergency situations. ■ All onsite vehicles will be monitored for leaks and receive regular preventative maintenance to reduce the chance of leakage. Any vehicle leaking fuel or hydraulic fuel will be immediately removed from the site. ABD Engineers,LLP 13 Corinth Road U-Store It 2 5010A-SWPPP 398 Corinth Road 6.22 Fertilizer Fertilizer will be stored in original containers and on pallets. Proper delivery scheduling will minimize storage time. Any damaged containers will be repaired immediately upon discovery and any released fertilizer recovered to the fullest extent practicable. 6.23 Paints All containers will be tightly sealed and stored when not required for use. Excess paint will not be discharged to the stone water or wastewater system,but will be properly disposed of according to manufacturers' instructions or State and local regulations. 6.24 Concrete Trucks Concrete trucks will not be allowed to wash out or discharge surplus concrete or drum wash water on the site except in a designated upland area. Concrete truck washout will not be allowed to discharge into waters or wetlands at any time. 6.25 Asphalt Trucks Asphalt trucks shall not discharge surplus asphalt on the site. 6.3 SPILL CONTROL PRACTICES In addition to the good housekeeping and material management practices discussed in the previous sections of this plan, the following practices will be implemented for spill prevention and cleanup: ■ Manufacturer's recommended methods for spill cleanup will be clearly posted and site personnel will be made aware of the procedures and the location of the information and cleanup supplies. Any spill in excess or suspected to be in excess of two gallons will be reported to the NYSDEC Spill Response Unit. Notification to NYSDEC (1-800-457- 7362)must be completed within two hours of the discovery of the spill. ■ Materials and equipment necessary for spill cleanup will be kept in the material storage area onsite. Equipment and materials will include but not be limited to: absorbent pads,brooms, dust pans, mops, rags, gloves, goggles, kitty litter, sand, sawdust, and plastic and metal trash containers specifically for this purpose. ■ All spills will be cleaned up immediately after discovery. ■ The spill area will be kept well ventilated and personnel will wear appropriate protective clothing to prevent injury from contact with spilled substance. ■ Spills of toxic or hazardous material will be reported to the appropriate State or local government agency,regardless of the size. ABD Engineers,LLP 14 Corinth Road U-Store It 2 SOIOA-SWPPP 398 Corinth.Road ■ The spill prevention plan will be adjusted to include measures to prevent this type of spill from reoccurring, and how to clean up the spill if there is another one. A description of the spill, what caused it, and the cleanup measures will also be included. ■ The contractor/trained individual will be the spill prevention and cleanup coordinator. He will designate at least three other site personnel who will receive spill prevention and cleanup training. These individuals will each become responsible for a particular phase of prevention and cleanup. The naives of responsible spill personnel will be posted in the material storage area on the onsite construction office or trailer. ■ A Spill Response Report is contained in the SWPPP Forms. 7.0 LONG TERM POST-CONSTRUCTION INSPECTION AND MAINTENANCE After the site is completely stabilized, inspections will be performed at least twice a year(after the spring thaw and in the fall). Inspections shall also occur after major rain events. All swales and stormwater management systems will be inspected on a regular basis. Sediments will be pumped out and/or removed based on the monthly inspection. It will be the responsibility of The Owner,his heirs or assigns, for documenting these inspections and clean out work Post-construction regularly scheduled inspections and maintenance will be necessary to ensure the permanent structural features, such as the stormwater management basins and the conveyance system components, remain optimally functional and continue to reduce the risk of sediment loading of surface water bodies. The Owner shall overtake responsibility of inspecting and maintaining drainage and erosion control features over the lifetime of the structures and stormwater components. Maintenance personnel, employed by the Owner, must be aware of the SWPPP and should be trained to recognize signs that stabilization measures may not be performing optimally or are failing. The inspection of on-site stabilization measures will become part of routine preventative maintenance practiced by the Owner and his employees. Inspection and maintenance should be performed as described below. ABD Engineers,LLP 15 Corinth Road U-Store It 2 5010A-SWPPP 398 Corinth Road Inspection Overall Site Inspection The overall site, embankments, and vegetation should be inspected regularly after every major rain event and at least twice a year (after the spring thaw and in the fall). The inspection should include but are not limited to: 1. Density and condition of vegetation and ground cover. 2. Erosion, differential settlement or cracking of ernbaiflQnent. 3. Bulging or sliding of toe of embankments. 4. Sedimentation of on-site or downstream water bodies. 5. Sedimentation of swales. 6. Sedimentation of lawn areas, paved areas. 7. Accumulation of pollutants, including oils or grease. 8. Damage of fatigue of storm associated components. Maintenance Overall Site Maintenance Maintenance vegetative and structural measures for soil protection is necessary to keep the storm water system functioning properly. Maintenance should occur on a regular basis and should include but is not limited to: Seasonal Maintenance 1. Vegetated areas should be maintained to promote vigorous and dense growth. Lawn areas should be mowed at least three times a year but may require more frequent mowing depending on the growth rate. 2. Paved areas should be swept at least twice a year and in the early spring for removal of deicing materials. 3. Accumulation of litter and debris should be removed during each mowing or sweep operation. 4. Structural components of the storm system should be addressed immediately following identification. 5. Cleanout of accumulated sediments and debris should occur. 6. Basin and drainage way maintenance will include periodic mowing, occasional spot reseeding and weed control. Weeds and woody plants should be eradicated or cut back since they reduce the drainage efficiency. 7. Signs of scour should be repaired. Weeds and brush growth should controlled as needed. 8. Sediment buildup is removed when 25% of the volume has been exceeded. ABD Engineers,LLP 16 Corinth Road U-Store It 2 5010A-SWPPP 398 Corinth Road Winter Maintenance I. Remove snow and ice away from culvert end sections. 2. Snow removed from paved areas should not be piled within the stormwater management basins. 3. Use of deicing materials should be limited to sand and environmentally friendly chemical products. Use of salt mixtures should be kept to a minimum. 4. Sand used for deicing should be clean, course material free of fines, silt, and clay. 5. Materials used for deicing should be removed during the early spring by sweeping and/or vacuuming. Stormwater Management Facility Maintenance I. Side slope, embankments, inlets and overflow spillways should be mowed at least three times a year but may require more frequent imowings depending on the growth rate. 2. Accumulation of litter and debris should be removed during each mowing or sweep operation. 3. Structural components of the basin which require repair or replacement should be addressed immediately following identification. 4. Sedimentation of stormwater management basins is dependent on storage capacity, inflow and sediment load. Basins should be monitored periodically for sediment accumulation. Sediments should be removed after 25% of the volume capacity has been lost, inlets/outlets become clogged or restricted, or when 12 inches has accumulated. When sediment removal is required, original grades should be restored as shown on the Construction Plans. 5. Spillways should be cleared of obstructions. 6. Inlet/outlet riprap damage due to scour be repaired. 7. Stormwater Management Facility shall be inspected and maintained at a minimum as specified in the NYSDEC Stormwater Management Design Manual.
