TBD PO Box 171 2452 State Route 9 Watervliet,NY 12189 Suite 301 (518)423-1804 Malta,NY 12020 (518) 899-5243 2.0 SITE DESCRIPTION This section briefly describes existing and proposed hydrologic and hydraulic conditions at and around the project site as they relate to surface water management planning considerations. Subsequent sections contain a description of the manner in which site runoff will be managed to minimize effects on areas adjacent to the site. 2.1 Location The proj ect is located at 3 8 Stafford Bridge Road, approximately 2,000 feet south of the intersection of Stafford Bridge Road and Lake Ave in the City of Saratoga Springs. The parcel encompasses approximately 2.64 acres and is currently vacant. The parcel is located within the RR—Rural Residential District which permits single family dwellings. 2.2 Topography The site generally slopes form a peak within the central portion of the parcel towards the parcel boundaries on each side of the peak. The parcel is currently being excavated and material is being removed to level the proj ect site. 2.3 Wetlands and Watercourses The parcel does not contain wetlands or watercourses. 2.4 Threatened/Endangered Species The parcel does not contain any threatened or Endangered Species. 5 of 20 2.5 Land Cover The proj ect site is currently woods with an area devoid of vegetation due to the excavation. 2.6 Soils � Oakville Loainy Fine Sand, (OaC)—(Rolling): This is a very deep,well drained soil formed in water sorted sand. It is on glacial outwash plains,lake plains,and beach ridges. The permeability is rapid throughout the mineral soil. The erosion factor is moderate. (Hydrologic Soil Type A) 2.7 Existing Land Use The proj ect site is currently vacant land. 3.0 PROJECT DESCRIPTION The proposed proj ect will include the development of a single family home with an accessory barn structure. The proposed residence will be serviced by an individual well and wastewater treatment system. An easement is proposed from Stafford Bridge Road to the land locked parcel which will include the driveway to the single family residence. Disturbance of the existing vegetation will be minimized to the greatest extend possible. 4.0 STORMWATER EROSION AND SEDIMENT CONTROLS Several types of temporary erosion and sediment controls are required during construction as shown on the proj ect plans and per the General Permit. Guidelines and recommendations can be found in the "New York Standards and Specifications for Erosion and Sediment Control." Selection of temporary stormwater controls will be on an "as needed basis" and will depend on the specific conditions of the site. Since site characteristics can change significantly during construction, it is important to monitor the site regularly to ensure the proper selection and implementation of the necessary controls. 4.1 Erosion and Sedimentation Controls Tempo�a�v Stabilization These controls include, but are not limited to stabilized construction entrances, silt fence, construction fencing, rolled erosion control product,mulch, soil stockpile areas, and staging and waste areas. Stabilized Construction Ent�ance This temporary structural measure is a stabilized pad of aggregate underlain with filter fabric located at any point where traffic will be entering or leaving a construction site to or from a public right-of-way, street, alley, sidewalk or parking area. The purpose of a stabilized construction entrance is to reduce or eliminate the tracking of sediment onto public rights-of-ways or streets. The entrance shall be maintained in a condition which will prevent tracking of sediment onto public right-of-way, street, alley, sidewalk or parking area. This may require periodic top dressing with additional aggregate. This will remain in place and be maintained until the proj ect site has been permanently stabilized. Silt Fencin� This temporary structural measure is a temporary barrier of geotextile fabric used to intercept sediment laden runoff from small drainage areas of soiL It is installed along the perimeter of impacted areas and along the base of fill slopes. Silt fencing is effective in reducing stormwater runoff velocities, assist in the deposition of transported sediment load and prevent erosion of soils onto adjacent areas. Maintenance shall be performed when the silt fencing has been damage or collapsed and material removed when "bulges" (generally when the 6 of 20 depth of sediment equals 1/3 of the fence height) develop in the silt fence. These will remain in place and be maintained until the proj ect site has been permanently stabilized. Construction Fencin�, Chain Link Fencin�o�Fla��in� This temporary structural measure is installed along the perimeter of the proj ect area. In many cases the limits of disturbance will coincide with the fencing or flagging or indicate buffer areas to be protected. The fencing or flagging is effective when used to separate the proj ect area from the adj acent areas used by the public. Construction Fencing, Chain Link Fencing or Flagging is relatively low maintenance, but should be repaired when damaged. These will remain in place and be maintained until the project site has been permanently stabilized. Rolled Erosion Cont�ol Product(RECP) This temporary structural measure is installed in areas that have steep slopes (generally greater than 3:1) to stabilize the slope and reduce the erosion potential. RECP's types include jute netting, straw blankets, wood fiber (excelsior) blankets, polypropylene blankets, straw-coconut blankets, coconut fiber blankets, etc. The RECP's are typically impregnated with grass seed and sometimes stapled to the exposed soil. Inspect RECP's after each rain event and repair if needed, including installing additional material and staples. If the RECP is undermined, roll back the material, add soil to finish grade and replace the material with staples as needed. In most cases,these will remain in place permanently(degrading over weeks,months or even years). Mulchin� This temporary structural measure is a plant residue or other suitable material that is applied to the bare soil surface to prevent soil erosion. Mulching is effective in conserving moisture and modifying surface soil temperature fluctuations, prevent surface compaction or crushing, reduce runoff and erosion, control weeds and help establish plant cover. Mulching types include plant fibers such as hay or straw, chipped native materials, green or composted organic materials, wood or bark chips, hydraulic mulches from recycled paper, hydraulic mulches from wood fiber, and hydraulic matrices (bonded fiber matrix). Inspect mulches after each rain event and repair if needed, including applying additional mulch. These will remain in place permanently (degrading over weeks,months or even years). Soil Stockpile A�eas These are approved locations where topsoil and other soil materials may be stored. These stockpiles will be protected from erosion by a number of inethods, including installing silt fencing around the down gradient perimeter of the stockpile and seeding and mulching the stockpile when not in use for more than 14 days,unless the stockpile will be active within 21 days. Sta�in�and Waste A�eas These are approved locations where non-soil, non-erodible materials may be stored. Soils shall not be stored in these areas. Proj ect plans specify the location, size, quantity, and details of the selected temporary measures. Steep slopes and exposed soils should be stabilized with silt fences, mulching blankets, geo-textiles, geo-synthetic drainage netting, hay or any other stabilization measure shall be used that will significantly reduce the risk of erosion. Stabilization measures should be initiated as soon as practical in portions of the site where construction activities have temporarily or permanently ceased, but in no case more than 14 days. All disturbed areas will be reclaimed by use of permanent vegetation, impervious surfaces including structures and paved driveways and roads. 7 of 20 4.2 Other Pollutant Controls Paints and Solvents During construction, temporary structures such as construction trailers may be moved on site to store items such as paints, solvents and gasoline pertinent to the continuation of construction activities. The intention of these structures is to shelter potential contaminants from stormwater and reduce the potential of toxic chemicals from entering the stormwater runoff due to construction activities. Solvents and detergents may be stored on-site that will be used for regular cleaning and maintenance of construction vehicles or temporary structures. Solvents shall be used in cleaning machinery pursuant to 6 NYCRR Part 750. After use, solvents shall be disposed of in approved containers and removed from site at scheduled intervals. Vehicle wash water that contains detergents must be disposed of into the sanitary sewer. Conc�ete Washout In the event concrete is delivered and placed on site, delivery trucks will require an area to stockpile barrel/cone, shutes, and other equipment. A centrally located concrete washout area approximately 15-feet square and 2.5- feet deep shall be constructed and lined with a 10 mil minimum poly/plastic liner. This washout area shall be enclosed by silt fence, located next to a paved road and situated a minimum of 50-feet from a watercourse. If required, temporary diversion dikes shall be constructed around washout area to prevent stormwater from entering washout location. Waste material from concrete washout operations shall be periodically removed and legally disposed of when two-thirds of the washout storage area has accumulated with material and a new liner shall be installed. At the end of construction all material from the washout area shall be removed and disposed of. Mate�ial Stockpile A�ea Materials utilized for construction or equipment storage areas shall be constructed to prevent runoff from coming in contact with stored items/equipment. Contractor shall clear area(s) indicated on proj ect plans and excavate into native material a minimum of 6-inches for placement of Marafi 100X fabric and 6-inch stone pad. Contractor to verify that area to be utilized is dry and stable and notify engineer if area shown on proj ect plans is not adequate. No materials/equipment shall be constructed within 50-feet of a water course. If necessary, temporary perimeter dikes shall be constructed to prevent runoff from entering the stone pad. Silt fencing shall be installed a minimum of 5-feet downslope of storage area. Should additional area be required the contractor shall construct additional storage areas as necessary in conformance with the proj ect plans, any additional areas are to be documented by contractor in the on-site SWPPP. Soil Stockpile A�ea During cut and fill operations topsoil and other excavated material will be stockpiled on site for placement in fill areas as construction progresses. In an effort to prevent runoff from coming in contact with stockpiled soils or soils from entering existing watercourses, managed stockpile areas shall be constructed in the areas indicated on the project plans. The contractor shall verify that the proposed areas are dry and stable, and to notify the engineer if area is not adequate. No soils or excavated materials shall be stockpiled within 50-feet of a watercourse. Contractor shall install silt fence 5-feet downslope of each pile and construct any perimeter diversion dikes if required. Material shall be stabilized with seed and mulch if not to be utilized/disturbed within 14 days unless stockpile is projected to be disturbed within 21 days. Seed and much will reduce wind blown and rain instigated erosion from the stockpiles exposed steep slopes. 8 of 20 Fuels Fuel for construction equipment shall either be obtained from a licensed distributor of petroleum products or from an approved above ground storage tank on site. A distributor may be contracted to arrive on site periodically and fill all equipment as necessary. All distributors of petroleum products must have adequate liability insurance to mitigate and clean up any spills that occur on site as well as obtain appropriate permits and licenses from the NYSDEC. All above ground storage tanks with a combined capacity of 1,100 gallons shall be installed pursuant to 6 NYCRR Part 614 Standards for New and Substantially Modified Petroleum Storage Facilities. Fuel from construction vehicles may come into contact with stormwater when vehicles are stored outside. Good housekeeping and preventative maintenance procedures shall be implemented to ensure fuel spills and leaks are minimized during refueling and storage. Any small-scale fuel or oil spills must be remedied immediately and contaminated soils shall be disposed of appropriately. The designated spill prevention and response team shall handle large-scale gasoline spills. Oil and other petroleum products may be stored on site in limited quantities to ensure the continued operation of construction equipment in the event a scheduled delivery is unavailable. Items shall be stored in their original containers within temporary structures and shall not be exposed to stormwater. Used oil and petroleum products shall be stored in approved containers until recycled or disposed of at an approved disposal facility. Tempora�v Facilities Temporary sanitary facilities may be located on site for construction workers. This facility shall be located in an accessible and visible location. Such a facility shall be leak and tip proof. A waste management company may be contracted to arrive on site and provide the routine pumping and sanitization of the facility. Such a company shall have adequate liability insurance to mitigate and clean up any spills that occur on site as well as appropriate permits and licenses from the NYSDEC. Dust Cont�ol Construction traffic must enter and exit the site at the stabilized construction entrance. The purpose is to trap dust and mud that would otherwise be carried off-site by construction traffic. Water trucks will be used as needed during construction to reduce dust generated on the site. Dust control must be provided by the General Contractor to a degree that is acceptable to the Owner, and in compliance with applicable local and state dust control regulations. Solid Waste No solid materials, including building materials, are allowed to be discharged from the site with storm water. All solid waste, including disposable materials incidental to the major construction activities, must be collected and placed in containers. The containers will be emptied periodically by a contract trash disposal service and hauled away from the site. The�mal Pollution Stormwater that comes in contact with roadways, driveways, parking lots or other impermeable surfaces may increase in temperature during warm weather. If stormwater is discharged into surface water bodies, the temperature of the water body may also increase, potentially threatening plant and animal species sensitive to temperature changes as well as providing an environment that may cause nuisance species to flourish. After development is complete, impervious areas shall be graded to sheet flow to adjacent vegetated areas before entering surface waters. 4.3 Best Management Practices Throughout construction, care shall be taken to ensure sediment does not enter surface water bodies and chemicals do not enter stormwater, potentially contaminating surface and groundwater supplies. The following 9 of 20 Best Management Practices (BMP) shall be observed to maintain responsible environmental practices on the construction site. Good Housekeepin� Good housekeeping is essential to reducing the risk of contaminating runoff waters during every stage of construction. The General Contractor shall ensure supervisors train each employee in good housekeeping practices as they pertain to the implementation of this SWPPP. Immediately following mobilization, the General Contractor shall take an inventory of all equipment and containers containing hazardous or toxic materials and submit this inventory to the Owner to keep on-site with this Stormwater Pollution Prevention Plan. This inventory shall be updated regularly to reflect changes in the quantity or type of hazardous and toxic materials stored on site. In the event of a spill, the Spill Response Team can refer to the inventory if the contents of the spill are unknown. All equipment shall be operational while it is stored on site. Inspections shall be conducted regularly to ensure all equipment is free of leaks and that oil and grease are not in contact with soils or stormwater. Portable equipment such as chain saws, drills as well as hand tools must be placed within a trailer or under cov er at the end of each work day. A storage area shall be designated on-site where all hazardous or toxic materials are stored. Each employee shall return the materials to the designated storage area following use. Chemicals, including oil, grease, solvents and detergents shall be stored on-site in approved containers only. Used chemicals shall be disposed of in refuse containers and removed periodically. Containers shall be regularly inspected to ensure the integrity of the container and seals to prevent leaks. A scheduled clean-up shall occur at the end of each workweek. During this clean up, empty containers of solvents, oils, grease,paints and detergents shall be disposed of, containers of gasoline shall be placed in trailers where they are not in contact with stormwater and the inventory shall be updated. Empty containers shall not be permitted on the ground. P�eventative Maintenance All on-site vehicles must be inspected regularly for oil and grease leaks. All leaks shall be repaired immediately upon obtaining the appropriate equipment. If the leak cannot be fixed immediately, it shall be temporarily mitigated to prevent the flow of contaminants onto the soil and potentially into the stormwater. If necessary,the reservoir will be drained to stop the flow of contaminants or the vehicle will be moved under cover. Drip pans shall be used when performing any maintenance or cleaning on construction vehicles. Spill Prevention and Response The safety of employees and neighbors shall be of utmost concern when hazardous or toxic chemicals are stored or utilized on-site. Materials Safety Data Sheets (MSDS) shall be obtained for all toxic or hazardous substances that are stored on-site to provide employees with a valuable database in assessing risk in the event of a spill. Any above ground storage tanks on site shall be installed pursuant to 6 NYCRR Part 614. According to the New York State "Minimum Standards for New and Substantially Modified Above Ground Storage Facilities", all tanks installed must meet or exceed the design criteria in one or more of the following design or manufacturing standards: UL No. 142, UL No. 58, API Standard No. 650, API Standard No. 620, CAN4-S601- M84 or CAN4-S630-M84. Tanks constructed of wood, concrete, aluminum, fiberglass reinforced plastic as well as riveted or bolted steel tanks are not permitted. All tanks must have installed leak detection systems, secondary containment, corrosion protection, and undergo periodic monitoring pursuant to all Part 614 requirements. Should a spill occur, trained individuals shall be on-call at all times to mitigate the potential negative effects of a spill. The General Contractor shall have trained employees knowledgeable in the location of sorbent, brooms, 10 of 20 rags and mops in the event of a small-scale spill. An inventory of equipment and its location shall be posted in a visible location as well as kept in proximity to this SWPPP. If the General Contractor does not have Hazardous Materials trained employees on site, a firm that specializes in handling spills, soil and water contamination shall be called. After a spill occurs, all personnel not trained in hazardous materials spill response shall be asked to evacuate the immediate area. The New York State NYSDEC of Environmental Conservation (NYSDEC) Spill Response Team shall be called to investigate the spill and determine if additional actions should be taken to ensure the safety of personnel and nearby residents. Should any employee have a suspected injury, a local emergency squad must be contacted immediately. 5.0 CONSTRUCTION SEQUENCE SCHEDULING (PHASING PLAN) Temporary stabilization methods will be implemented before construction begins and will be continuously modified throughout the proj ect to provide the best methods for stormwater management and pollution prevention. For more details pertaining to construction sequence, please refer to the "NYSDEC Instruction Manual for Stormwater Construction Permit" pages 23-26. The proj ect is anticipated to begin in summer of 2017 and end in the fall of 2018, although full build out of lots will be based on market conditions. Phasing of activities is as follows: P�e-Const�uction Activities � Owner and Contractor to review this document with all employees and subcontractors to gain understanding of the management features and sediment controls outlined in this document as they relate to the engineered project plans. • Perform a site investigation to identify all natural resources and mark and protect them as necessary i.e. trees, vegetation, and wetlands. Note any discrepancies that may exist between the site and what is shown on the engineered proj ect plans as they pertain to existing watercourses, ground cover, topography, wetlands, etc. � Notify design engineer of any discrepancies. • Identify on site and downstream surface water bodies and install controls to protect them from sedimentation. • Establish a temporary stabilized construction entrance per the New York State Standa�ds and Specifications fo�E�osion and Sediment Cont�ol Handbook, July 2016, to capture mud and debris from the tires of construction vehicles. • Install perimeter sediment controls such as silt fence as shown on the project plans. • All earth disturbance during this phase should be limited to work necessary to install erosion and sedimentation controls. Du�ing Const�uction Activities • Install runoff and drainage controls as shown on the proj ect plans and as necessary. These controls should reduce run-off flow rates and velocities as well as divert off site and clean run-off. � Stabilize the conveyance system i.e. ditches, swales, berms etc. by seeding, mulching, installing rock check dams. � Stabilize all run-off outlets as shown on the project plans and as necessary. • Limit soil disturbance to small areas and preserve as much of the existing vegetation as practical. • All topsoil stockpiles should be staged in an area away from surface waters and storm drains and should be protected and stabilized. • Earth disturbance is not allowed in established buffers, within any regulated distance from wetlands, within the high water line of a body of water affected by tidal action or other such protected zones. • At any location where surface run-off from disturbed or graded areas may flow off-site, sedimentation control measures must be installed to prevent sedimentation from being transported. 11 of 20 • Regular inspections and maintenance should be performed as described in the following section. � Construct temporary material storage and soil stockpile areas • In the event concrete is delivered and placed on site, delivery trucks will require an area to truck barrel/cone, chutes, and other equipment. A centrally located concrete washout area approximately 15- feet square and 2.5-feet deep shall be constructed. This washout area shall be enclosed by silt fence, located next to a paved road and situated a minimum of 100-feet from a watercourse. If required, temporary diversion dikes shall be constructed around washout area to prevent stormwater from entering washout location. � Waste material from concrete washout operations must shall be periodically removed and legally disposed of when two-thirds of the washout storage area has accumulated with material. At the end of construction all material from the washout area shall be removed and disposed of. • Remove perimeter silt fence when a permanent stand of vegetation is achieved. � Clear brush and trees within proposed building envelope. � Construct a temporary material stockpile area on individual lot for homebuilding construction. Size of area may vary per homebuilder; however general material/storage stockpile measures shown on construction drawings shall be followed. • Perform required grading and homebuilding operations • Perform required utility connections � Stabilize lawn areas not to be disturbed with seed and mulch • Pave driveway. � Stabilized remaining areas. • Remove temporary erosion and sediment control practices (i.e. silt fence) 6.0 IMPLEMENTING THE SWPPP 6.1 Employee Training All employees on site shall be aware of the stipulations of this SWPPP as it pertains to their everyday activities. All employees must be able to recognize potential problems and have the ability to provide temporary stabilization measures, as appropriate, to mitigate stormwater runoff before problems occur. The NYSDEC periodically holds workshops on erosion and sediment controL It is recommended that on site personnel attend these workshops to keep training current and up to date. All contractors and subcontractors involved with soil disturbing activities shall have at least one trained individual from their company be responsible for implementation of the SWPPP and be on site when soil disturbing activities are occurring. 6.2 Site Inspections The Owner shall ensure all erosion and sediment controls identified in the SWPPP are maintained and effective from commencement of construction to the filing of the NOT. The Owner shall inspect the erosion and sediment controls identified in the SWPPP to ensure they are installed and maintained in accordance with the most current version of the "New Yo�k Standa�ds and Specifications fo�E�osion and Sedi�nent Cont�ol". It is the responsibility of the Owner, Contractor and subcontractors to continuously monitor construction activities to ensure the measures outlined in this report are being implemented. The owner shall have a qualified inspector perform site inspections for construction activities identified in Table 1 and 2 of Appendix B of the NYSDEC SPDES General Permit (GP-0-15-002). A qualified professional is defined as a person such as a Professional Engineer, Certified Professional in Erosion and Sediment Control (CPESC)or a soil scientist. Once construction begins regular inspection of construction activities by the qualified professional are required at least once every seven (7) calendar days to ensure deficiencies regarding erosion and sedimentation are reported and corrected. Areas which have not been fully stabilized, areas used for materials storage and all 12 of 20 structural control measures must be inspected to monitor erosion and as sess the risk of sedimentation. The qualified inspector shall certify all inspection reports. Inspection reports will be faxed to the Owner, Contractor and subcontractors within one business day of the completion of the inspection. Corrective action to address any deficiencies at the site shall be initiated within one business day of receiving the notification. All erosion and sediment controls must be installed and maintained according to the New Yo�k Standa�ds and Specifications fo�E�osion and Sedi�nent Cont�ol. The main items to consider are: 1. Site Stabilization - All bare/exposed soils must be stabilized by an established vegetation, straw or mulch, matting, rock or other approved product such as rolled erosion control product. Seeding of areas along with mulching is encouraged, however seeding alone is not considered acceptable for proper stabilization. 2. Sediment Barriers - Barriers must be properly installed at all necessary perimeter and sensitive locations. 3. Slopes - All slopes and grades must be properly stabilized with approved methods. Rolled erosion control products must be used on all slopes greater than 3/1, or where conditions for erosion dictate such measures. 4. Soil Stockpiles - Stockpiled soils must be protected by the use of established vegetation, an anchored- down straw or mulch, rolled erosion control product or other durable covering. A barrier must be installed around the pile to prevent erosion away from that location. 5. Construction Entrance - All entrance/exit locations to the site must be properly stabilized and must be maintained to accommodate snow management as set forth in the New York Standards and Specifications for Urban Erosion and Sediment Control. 6. Snow Management - Snow management must not destroy or degrade erosion and sediment control practices. At the end of the construction season when soil disturbance activities will be finalized or suspended until the following spring, it may be desirable to reduce the frequency of the required inspections in accordance with NYSDEC Winter Site Stabilization Standards and Specifications. To be allowed to reduce inspection frequencies, the owner must notify the Regional Office stormwater contact person in writing prior to reducing the frequency of inspections. During periods of reduced inspection frequency, inspections must still be completed at least every thirty(30) days. The owner shall complete stabilization activities (perimeter controls, traps, barriers etc) before proper installation is precluded by snow cover or frozen ground. If vegetation is desired, seeding, planting, and/or sodding must be scheduled to avoid die-off from fall frosts and allow for proper germination/establishment. Frozen ground, winter conditions and equipment can affect erosion and sediment control practices. Check for damage during monthly inspections and repair as necessary. This is especially important during thaws and prior to spring rain events. Weekly inspections must resume no later than March 15 or as directed by the Department. If the soil disturbance is completely suspended and the site is properly stabilized it may be desirable to reduce the inspection frequency to a minimum of once every thirty (30) calendar days. To be allowed to reduce inspection frequencies, the owner must notify the Regional Office stormwater contact person in writing prior to reducing the frequency of inspections. The SWPPP shall be reviewed to evaluate its overall effectiveness in preventing sediment laden stormwater runoff. Temporary stabilization methods shall be assessed, and new methods shall be established, should any method be determined to be inadequate. All changes shall be included in the SWPPP. 13 of 20 A current copy of the SWPPP must be maintained on site at all times. The Owner shall maintain a copy of the General Permit, NOI, NOI Acknowledgement Letter, Contractor certifications, and inspection reports in the on site Logbook. All record keeping shall be maintained on site and be made available to the permitting authority upon request. 6.3 Maintenance It shall be necessary to maintain all temporary controls installed as well as vegetative measures across the site. During construction, maintenance of these stabilization measures shall be the responsibility of the Contractors and/or appropriate subcontractors. Vegetative plantings must not be allowed to become overgrown. Vegetation shall be removed should it be ineffective and be replaced with a variety of grasses, trees and shrubs more suitable for preventing stormwater runoff. Silt fences must be inspected regularly to ensure that they are still effective and their capability to reduce stormwater runoff has not been reduced due to prolonged sun exposure. Guidelines and recommendations for installation and maintenance practices can be found in the "New Yo�k Standa�ds and Specifications fo�E�osion and Sediynent Cont�ol". 6.4 Certification Prior to starting construction, the Owner must certify that to the best of their knowledge this SWPPP was prepared in accordance with the requirements in the NYSDEC SPDES General Permit and that it meets all federal, state and local erosion and sediment control requirements. The certifying statement is contained in the NOI. All appropriate contractors and subcontractors involved in soil disturbing activities are responsible for fully implementing the SWPPP. They are required to sign the certifying statement presented in Appendix A of this report. All weekly inspection reports are to be certified by the qualified inspector performing the on site inspections. 6.5 Proj ect Completion At the time of final stabilization, the OWner's Site Inspector shall perform a final site assessment to verify that all construction activity identified in the SWPPP has been completed, that all disturbance has undergone final stabilization and that all temporary erosion and sediment controls have been removed. Final stabilization as defined in the General Permit "means that all soil disturbance activities have ceased and a uniform, perennial vegetative cover with a density of eighty (80) percent over the entire pervious surface has been established; or other equivalent stabilization measures, such as permanent landscape mulches, rock rip-rap or washed/crushed stone have been applied on all disturbed areas that are not covered by permanent structures, concrete or pavement". Once a final site assessment has been conducted, a NOT shall be prepared and certified by the Owners' Site Inspector as described in Section 1.1 of this report. The NOT should then be signed by the Owner and submitted to the NYSDEC. All record keeping must be kept for at least five (5) years from the date that the site has achieved final stabilization. 14 of 20 App endix A: Site Location Map 15 of 20 App endix B: Erosion and Sediment Control Plan&Details 16 of 20 Appendix C: Notice of Intent (NOI) 17 of 20 Appendix D: Notice of Termination (NOT) 18 of 20 Appendix E: MS4 Stormwater Pollution Prevention Plan Acceptance Form 19 of 20 Appendix F: Contactor's Certification Page 20 of 20
