The qualified inspector shall, by signing the "final stabilization" and "Post-Construction Stormwater Management Practice certification statements on the NOT, certify that all requirements of the SPDES General Permit have been met. Further, construction activities subject to the requirements of a regulated, transitional land use control MS4, must have the MS4 sign the "MS4 acceptance" statement on the NOT, indicating that the project has been constructed in accordance SPDES General Permit requirements. Lastly, for construction activities that require post-construction stormwater management practices, the owner or operator must, prior to submitting the NOT, ensure one of the following: 1. The post-construction stormwater management practices and any right of ways needed to maintain such practices have been deeded to the municipality in which the practice is located. 2. An executed maintenance agreement is in place with the municipality that will maintain the post-construction stormwater management practices. 3. If the post-constructed management practices are privately owned, the owner or operator must have a mechanism in place that requires operation and maintenance of the practices in accordance with the 4 1 P a g e Stormwater Pollution Prevention Plan O'tooles Contractor Yard (T)Lansing,NY operation and maintenance plan, such as a deed covenant in the owner or operator's deed of record. 4. If the post-constructed practices are owned by a public or private institution, government agency or authority, or public utility, the owner or operator has policy and procedure in place that ensures operation and maintenance of the practices in accordance with the operation and maintenance plan. J. This SWPPP intends to control water-borne and liquid pollutant discharges by some combination of interception, filtration, and containment. The general contractor and subcontractors implementing this SWPPP must remain alert to the need to periodically refine and update the SWPPP in order to accomplish the intended goals. K. This SWPPP must be amended as necessary during the course of operations in order to keep it current with the pollutant control measures utilized at the site. Amending the SWPPP does not mean that it has to be reprinted. It is acceptable to add addenda, sketches, new sections, and/or revised drawings. L. A record of the dates when major grading activities occur, when construction activities temporarily or permanently cease on a portion of the site, and when stabilization measures are initiated must be maintained until the NOT is filed. A log for keeping such records is included in Attachment G. A different form for the log may be substituted if it is found to be more useful. 2.0 INTRODUCTION This SWPPP has been prepared for major activities associated with the ongoing operation of a contractor work yard in the Town of Lansing. The production originally started in 2011 which was allowed use by right through the Town. In 2016, a full site plan review process was conducted for a conceptual apartment complex located downslope from the facility which included an approved SWPPP. As part of the storm plan, the work yard was allowed continued use by right but several restrictions were placed on the property limiting the size and scope of the work zone while also requiring the installation of a stormwater management sump practice to provide runoff mitigation and attenuation. Because the apartment complex was never realized, the 2016 restrictions became null and void with the exception that the operation would now be required to carry its SWPPP. The O'tooles Contractor Work Yard is located in the Town of Lansing, New York at Tax Parcel #30.-1-28.212 at the intersection of Peruville and Scofield Roads. The property sits within a drainage area of approximately 10.32-AC of which, the cumulative on-going land disturbance is approximately 4.93 acres. The entire site 5 1 P a g e Stormwater Pollution Prevention Plan O'tooles Contractor Yard (T)Lansing,NY is assumed to be impervious given the fact that it is hard packed dirt due to typical work yard activity. The original 2016 project called for a 1' sump to capture and treat on-going runoff from the operation. The modified plan adds an additional 1' of depth to the practice to meet attenuation requirements but the footprint largely remains the same. Reference the Project Plans for the permanent stormwater management facilities planned. This SWPPP includes the elements necessary to comply with the SPDES General Permit for Stormwater Discharges GP-0-25-001 administered by the New York State Department of Environmental Protection, the U.S. Environmental Protection Agency (EPA) under the National Pollutant Discharge Elimination System (NPDES) program and all local governing agency requirements. This SWPPP must be implemented at the start of construction. Construction phase pollutant sources anticipated at the site are disturbed (bare) soil, vehicle fuels and lubricants, chemicals associated with various stockpiled materials (asphalt), and general debris. Without adequate control there is the potential for each type of pollutant to be transported by storm water. Aside from the commercial work site, an asphalt driveway apron, landscape screening, storage bunkers, and a hoop building are on the property. There are no utilities including water, sewer, or electric. Permanent stormwater management facilities are in place including one (1) dry sump. The pond will provide any water quality volume treatment and satisfy requirements for quantity attenuation necessary to control runoff to less than pre-developed conditions as required by the NYSDEC General SPDES Permit. Please see Attachment K for this information. A. Purpose The major goal of pollution prevention efforts during operations is to control the migration of soil and pollutants that originate on-site and prevent them from impacting surface waters and the environment. The purpose of this SWPPP is to provide guidelines for achieving that goal. A successful pollution prevention program also relies upon careful inspection and adjustments during the construction process in order to enhance its effectiveness. B. Scope This SWPPP must be implemented at all times while operations and soil disturbances are active on-site. It primarily addresses the impact of storm rainfall and runoff in areas of the ground surface disturbed during the work yard. This SWPPP will terminate when disturbed areas are stabilized, construction type activities covered herein have ceased, and a completed 6 1 P a g e Stormwater Pollution Prevention Plan O'tooles Contractor Yard (T)Lansing,NY Notice of Termination (NOT) is mailed to the governing agency requiring the NOT. See Section 1.0.I for specific NOT eligibility requirements. Particular forms are included which are necessary for implementing the SWPPP. The SPDES General Permit for Storm Water Discharges from Construction Activities prohibits most non-storm water discharges during the construction phase. Allowable non-storm water discharges that could occur during construction on this project, which would therefore be covered by the General Permit, include: 1. Discharges from fire fighting activities; 2. Fire hydrant flushing; 3. Waters to which cleansers or other components have not been added that are used to wash vehicles or control dust; 4. Routine external building washdown which does not use detergents; 5. Irrigation drainage; 6. Uncontaminated discharges from construction site de-watering operations; 7. External building wash down which does not use detergents; 8. Runoff from pavement wash down where spills or leaks of toxic or hazardous materials have not occurred (unless all spilled material has been removed) and where detergents have not been used; 9. Springs and uncontaminated groundwater; and 10. Foundation or footing drains where flows are not contaminated with process materials such as solvents. The techniques described in this SWPPP focus on providing control of pollutant discharges with practical approaches that utilize readily available expertise, materials, and equipment. The Owner/Developer referred to in this SWPPP is Scott Pinney who will be responsible for full development and build-out of the subject parcel. 7 1 P a g e Stormwater Pollution Prevention Plan O'tooles Contractor Yard (T)Lansing,NY 3.0 PROJECT DESCRIPTION Described below are the major construction activities that are subject to this SWPPP. The Owner shall not disturb greater than five (5) acres of soil at an, one time without prior written authorization from the DEC, or, in areas under the jurisdiction of a regulated MS4, authorization by that municipality. They are presented in the order (or sequence) they are expected to begin, but each activity will not necessarily be completed before the next begins. Install erosion and sediment control measures as shown on Drainage, Sediment and Erosion Control Plans, down slope from construction activities that disturb site soil before disturbance of soil; CONTRACTOR YARD — REQUIRED FOR ON-GOING OPERATIONS A. Increase volume of existing dry pond (sump) by establishing another foot in depth with side slope of 4:1 and as shown on plan sheets S-1 and S-2. Note: Sediment barriers such as silt fencing, proper seeding and mulching will be utilized as required to bind the down slope side of the pond and soil stockpiles shall be established as needed; B. Remove any accumulated sedimentation from the pond as accumulations increase by at least 6" 4.0 RUNOFF REDUCTION VOLUME This project follows guidelines set forth by the DEC for runoff reduction. Chapter 3 of the New York State Stormwater Management Design Manual requires a five step planning process to document compliance with required processes. However, as this is a contractor yard with operations that have already been in place for the past 15 years, much of this section is exempt from consideration. Step 1 — Protect natural resources and utilize site hydrology This planning step is designed to preserve area natural resources by protecting areas, avoiding sensitive locations, and minimizing grading and soil disturbances. There were no erodible soils, critical areas, wetlands, riparian buffer areas, or locally listed protected areas. Another component of the planning process is an evaluation of all green infrastructure practices that might be acceptable for runoff reduction on site. This project will utilize filter strips. The selection process is described as follows: 8 1 P a g e Stormwater Pollution Prevention Plan O'tooles Contractor Yard (T)Lansing,NY o Conservation of natural areas — Pre-development hydrology and water quality characteristics of undisturbed natural areas remains unaltered. o Sheetflow to riparian buffers o Vegetated open swales — Site runoff will be collected and directed to specific treatment practices using the site's existing slope to direct sheet flow. o Tree planting/tree box o Disconnection of rooftop runoff o Stream daylighting for redevelopment projects o Bioswale o Green roof o Stormwater planters o Rain cistern o Porous pavement Step 2 — Determine Overall Water Quality Treatment Volume (WQvv) See Attachment K for the calculation summary. Step 3 — Runoff reduction by pplyin green infrastructure technology and standard SMPs. Runoff reduction was calculated as required. Flow is directed into a dry pond sump which acts as an infiltration practice. 100% of the site water quality volume is captured. As shown in Attachment K, minimum requirements for runoff reduction volume were met. Step 4 — Provide standard practices to address remaining water quality volume A dry pond captures 100% of the water quality volume. Reference Attachment K for the overall treatment calculations. 9 1 P a g e Stormwater Pollution Prevention Plan O'tooles Contractor Yard (T)Lansing,NY Step 5 —Apply volume and peak rate control practices if still required Peak rate control is met using one dry pond. The pond reduces runoff from the operation to less than pre-developed conditions. See modeling report output for further information. 5.0 STORM WATER POLLUTION PREVENTION MEASURES AND CONTROLS Various erosion and sediment control measures have been incorporated into the design of the project, Reference Stormwater, Sediment and Erosion Control Plans accompanying this SWPPP. These measures will be implemented during operations to minimize soil erosion and to protect the character and integrity of downstream receiving waters. A single dry pond (sump) is used to control the quality and quantity of storm water runoff from the work yard site. The site owner shall take all appropriate precautions to prevent soil erosion and discharge of sediment and other pollutants to receiving water bodies and wetlands. Specific measures are outlined in this plan. In general, disturbance areas shall be limited to the smallest practical areas at any given time, and the areas are to be reseeded as soon as possible. During construction the measures outlined in this document and shown on the plans are to be installed as described. Additional measures may be warranted or required by site and climatic conditions. Specific erosion control measures, designed to minimize soil loss, and sediment control measures devised to retain eroded soil and prevent it from reaching water bodies or adjoining properties have been developed in accordance with the New York State Stormwater Management Design Manual, 2015, NYSDEC and New York Standards & Specifications for Erosion and Sedimentation Control, November 2016. Reference Attachment H for copy of Vegetative and Structural, Measures for Erosion and Sediment Control, New York State Standards & Specifications for Erosion and Sedimentation Control. (Vegetative; November 2016, Structural; August 2005) A variety of storm water pollutant controls are recommended for this project. Some controls are intended to function temporarily and will be used as needed for pollutant control during the operations. These include sediment and erosion control measures as shown on the plans and permanent stormwater facilities including, a dry pond. For all disturbed areas, permanent stabilization will be accomplished by covering the disturbed soil with vegetation, pavement, or commercial structures. A. Erosion and Sediment Controls 1. Soil Stabilization — The purpose of soil stabilization is to prevent soil from leaving the site. In the natural condition, soil is stabilized by 101Page Stormwater Pollution Prevention Plan O'tooles Contractor Yard (T)Lansing,NY native vegetation. The primary technique to be used under this project for stabilizing site soil will be to provide a protective cover of turf grass, pavement, or building structure. a. Temporary Seeding - Where land disturbance is necessary, temporary seeding with fast-germinating temporary seed and a protection of mulch must be used on areas which will be exposed for more than 14 days. b. Permanent Seeding — All areas at final grade must be seeded and mulched within 7 days after completion of the major activity. c. Structural Controls — The storm water will be managed on site utilizing proposed site grading and a dry. Their design is shown on the Project Site Stormwater Plan S-1 and S-2. Final site stabilization is achieved when there is a uniform 80 percent density of permanent vegetation on all previously disturbed soil surfaces, exclusive of areas that have been paved. B. Other Pollutant Controls Control of sediments has been described previously. Other aspects of this SWPPP are listed below: 1. Dust Control — Construction traffic must enter and exit the site at the stabilized work yard/driveway entrance. The purpose is to trap dust and mud that would otherwise be carried off-site by construction traffic. Dust control must be provided by the owner, and in compliance with applicable local and state dust control regulations. After operations are complete, the site will be stabilized (as described elsewhere), which will reduce the potential for dust generation. 2. Solid Waste Disposal — No solid materials are allowed to be discharged from the site with storm water. All solid waste, including disposable materials incidental to the major work yard 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. Substances that have the potential for polluting surface and/or groundwater must be controlled by whatever means necessary in order 111Page Stormwater Pollution Prevention Plan O'tooles Contractor Yard (T)Lansing,NY to ensure that they do not discharge from the site. As an example, special care must be exercised during equipment fueling and servicing operations. If a spill occurs, it must be contained and disposed so that it will not flow from the site or enter groundwater, even if this requires removal, treatment, and disposal of soil. In this regard, potentially polluting substances should be handled in a manner consistent with the impact they represent. 3. Sanitary Facilities —There are no sanitary facilities on-site. 4. Water Source — There are no water sources provided on-site. 5. Long-Term Pollutant Controls — Storm water pollutant control measures installed during construction that will also provide benefits during operations, include one (1) dry pond. Those sediment barriers, such as check dams (if required), that do not interfere with normal operations and appear to provide long-term benefits can be left in place after once operations are completed. All silt fencing must be removed once the site has received proper stabilization. C. Construction Phase "Best Management Practices" During the construction phase, the general contractor will implement the following measures: 1. Permanent traffic corridors shall be established and "routes of convenience" shall be avoided; 2. Preservation of existing vegetation as much as possible. Following the completion or closure of work yard operations and activities in any portion of the site permanent vegetation shall be established an all exposed soils; 3. Site preparation activities shall be planned to minimize the area and duration of soil disruption; 4. Minimizing soil erosion and sedimentation by stabilization of disturbed areas and by removing sediment from site discharges; 5. Material resulting from any clearing and grubbing operation will be stockpiled up slope from adequate sedimentation controls. 121Page Stormwater Pollution Prevention Plan O'tooles Contractor Yard (T)Lansing,NY 6. The owner will designate areas for equipment, maintenance, and stockpiling. The areas will be protected by a temporary perimeter berm. 7. Use of detergents for large scale washing is prohibited (i.e., vehicles, buildings, pavement surfaces, etc.) 8. Chemicals, paints, solvents, fertilizers, and other toxic material must be stored in waterproof containers. Except during application, the contents must be kept in trucks or within storage facilities. Runoff containing such material must be collected, removed from the site, treated and disposed at an approved solid waste or chemical disposal facility. 6.0 LOCAL PLANS In addition to this SWPPP, work yard activities associated with this project must comply with any guidelines set forth by local and state regulatory agencies. Reference Project Plans and the Stormwater Management Design Summary (Attachment K) prepared to meet Local and State requirements for post- development stormwater quantity & quality. 7.0 NYSHPO A search was conducted on the New York State Parks, Recreation and Historic Preservation Office website to identify whether the subject parcel is listed under natural or historic places registration, or if the area resides within an archaeologically sensitive location. Attachment D, includes a "grey map" indicating that the property is not within a sensitive area. 8.0 ENVIRONMENTAL MAPPING A search was conducted on the Tompkins County, New York State, and Federal Inventory websites to identify any areas with known wetlands, protected plants or animal species, or any significant environmental concerns that could be impacted by this project. No issues or concerns were noted. Please see Attachment E for screen prints of this review. 9.0 INSPECTIONS AND SYSTEM MAINTENANCE Between the time this SWPPP is implemented and final site stabilization is achieved, all disturbed areas and pollutant controls must be inspected at least once every seven calendar days by a licensed professional or Qualified Inspector, as identified by the SPDES General Permit. The purpose of site inspections is to 131Page Stormwater Pollution Prevention Plan O'tooles Contractor Yard (T)Lansing,NY assess performance of pollutant controls. The inspections will be conducted by an independent third party Qualified Inspector to be provided by the Owner using a form similar to the example provided in Attachment F. The Owner/Operator will also be required to arrange for a designated Trained Contractor (as defined by the SPDES General Permit) to be responsible for the management of this SWPPP during construction, while on-site. Based on these inspections, the Trained Contractor will decide whether it is necessary to modify this SWPPP, add or relocate sediment barriers, or whatever else may be needed in order to prevent pollutants from leaving the site via storm water runoff. The Trained Contractor has the duty to cause pollutant control measures to be repaired, modified, maintained, supplemented, or whatever else is necessary in order to achieve effective pollutant control. Examples of particular items to evaluate during site inspections are listed below. This list is not intended to be comprehensive. During each inspection the inspector must evaluate overall pollutant control system performance as well as particular details of individual system components. Additional factors should be considered as appropriate to the circumstances. A. Construction of stormwater facilities. Insure facilities are constructed substantially in accordance with the plans. (Also, Reference Attachment I for sample inspection checklist - NYSDEC Stormwater Construction Checklist): B. Locations where vehicles enter and exit the site must be inspected for evidence of off-site sediment tracking. A stabilized construction entrance will be monitored where vehicles enter and exit. This entrance will be maintained or supplemented as necessary to prevent sediment from leaving the site on vehicles. C. Sediment barriers must be inspected and, if necessary, they must be enlarged or cleaned in order to provide additional capacity. All material from behind sediment barriers will be stockpiled on the up slope side. Additional sediment barriers must be constructed as needed. D. Inspections will evaluate disturbed areas and areas used for storing materials that are exposed to rainfall for evidence of, or the potential for, pollutants entering the drainage system. If necessary, the materials must be covered or original covers must be repaired or supplemented. Also, protective berms must be constructed, if needed, in order to contain runoff from material storage areas. E. Grassed areas will be inspected to confirm that a healthy stand of grass is maintained. The site has achieved final stabilization once all areas are covered with building foundation or pavement, or have a stand of grass with 141Page Stormwater Pollution Prevention Plan O'tooles Contractor Yard (T)Lansing,NY at least 80 percent density. The density of 80 percent or greater must be maintained to be considered as stabilized. Areas must be watered, fertilized, and reseeded as needed to achieve this goal. F. All discharge points must be inspected to determine whether erosion control measures are effective in preventing significant impacts to receiving waters. Based on inspection results, any modification necessary to increase effectiveness of this SWPPP to an acceptable level must be made within seven calendar days of the inspection. The inspection reports must be completed entirely and additional remarks should be included if needed to fully describe a situation. An important aspect of the inspection report is the description of additional measures that need to be taken to enhance plan effectiveness. The inspection report must identify whether the site was in compliance with the SWPPP at the time of inspection and specifically identify all incidents of non-compliance. Inspection reports must be kept on file by the Trained Contractor as an integral part of this SWPPP for at least five years from the date of completion and filing of NOT for the project. Ultimately, it is the responsibility of the site Trained Contractor to assure the adequacy of site pollutant discharge controls. Actual physical site conditions or contractor practices could make it necessary to install more structural controls than are shown on the plans. (For example, localized concentrations of runoff could make it necessary to install additional sediment barriers.) Assessing the need for additional controls and implementing them or adjusting existing controls will be a continuing aspect of this SWPPP until the site achieves final stabilization. 10.0 POST CONSTRUCTION INSPECTION, OPERATION AND MAINTENANCE PLAN A. Maintenance Responsibility Short and Long term maintenance responsibilities for the dry pond shall lie with the owner, Scott Pinney. 1. Copies of the SWPPP and details about the dry pond practice shall also be forwarded to the Town of Lansing for archival purposes. 151Page Stormwater Pollution Prevention Plan O'tooles Contractor Yard (T)Lansing,NY B. Sediment & Debris Removal Silt/sediment shall be removed from the dry pond when the accumulation exceeds 6 inches. The removed sediments shall be disposed in an acceptable manner (ie. Landfill) C. Inspection & Periodic Maintenance To ensure the continued operation and long term performance of the proposed Stormwater management system(s), inspections shall be conducted periodically for the first few months following any inactivity of the contractor work yard and then on an annual basis. Site inspection should also be performed following major storm events (i.e., intense storms, thunder storms, cloud bursts, etc.). Items to check for include, but are not limited to the following: (Reference Attachment J for complete inspection checklist - NYSDEC Stormwater Operation, Maintenance and Management Inspection Checklists): i) Embankment & Structural; ❑ Check basin embankments, outlets and spillways note cracks, bulges, animal burrows, differential settlement, damage to or fatigue of stormwater pipe, structures and permanent erosion control. Components of the system that require repair or replacement should be addressed immediately following identification. Check pipes, channels, grates, inlet structures and spillways to insure design capacity. Look for objects or accumulations of sediments and debris obstructing flow path. ii) Vegetation; ❑ Preclude deep rooted woody plant growth on structure embankment by mowing at least once annually. ❑ Maintain a dense vigorous growth of grass cover. Spot seed, mulch and fertilize where necessary. 161Page Attachment A: Notice of Intent, (NOI) and MS4 Acceptance Form (if applicable) 9/18/26, 1:31 PM NYSDEC eBusiness Portal System-Construction General Permit(CGP)Electronic Notice of Intent(eNOI)GP-0-25-001.Revision 1 Construction General Permit (CGP) Electronic Notice of Intent (eNOI) GP-0-25-001 version 1.19 (Submission M HQR-NMYQ-WXG2F,version 1) Details Originally Started By Scott Gibson Alternate Identifier O'Tooles Contractor Yard—Region 7 Submission ID HQR-NMYQ-WXG2F Status Draft Form Input Eligibility Disturbance Threshold 1.Will the construction activity involve soil disturbances listed in Part I.A.1 of GP-0-25-001?

If soil must be fertilized before results of a soil test can be obtained to determine fertilizer needs,apply commercial fertilizer at 600 lbs.per acre of 5-5 -10 or equivalent. If manure is used,apply a quantity to meet the nutrients of the above fertilizer. This requires an appropriate manure analysis prior to applying to the site. Do not use manure on sites to be planted with birdsfoot trefoil or in the path of concentrated water flow. 4 Seed mixtures may vary depending on location within the state and time of seeding. Generally,warm season grasses should only be seeded during early spring,April to May. These grasses are primarily used for vegetating excessively drained sands and gravels. See Standard and Specification Definition & Scope for Sand and Gravel Mine Reclamation. Other grasses may be seeded any time of the year when the soil is not frozen Establishing permanent grasses with other forbs and/or and is workable. When legumes such as birdsfoot trefoil shrubs to provide a minimum 80%perennial vegetative are included, spring seeding is preferred.

Time of Seeding: The optimum timing for the general seed mixture is early spring. Permanent seedings may be made any time of year if properly mulched and adequate moisture is provided. Late June through early August is not a good time to seed,but may facilitate covering the land without additional disturbance if construction is completed. Portions of the seeding may fail due to drought and heat. These areas may need reseeding in late summer/fall or the following spring. Method of seeding: Broadcasting,drilling,cultipack type seeding,or hydroseeding are acceptable methods. Proper soil to seed contact is key to successful seedings. Mulching: Mulching is essential to obtain a uniform stand of seeded plants. Optimum benefits of mulching new seedings are obtained with the use of small grain straw 50%Perennial Vegetative Cover applied at a rate of 2 tons per acre,and anchored with a netting or tackifier. See the Standard and Specifications for Mulching for choices and requirements. Irrigation:.ion: Watering may be essential to establish a new seeding when a drought condition occurs shortly after a new seeding emerges. Irrigation is a specialized practice and care must be taken not to exceed the application rate for the soil or subsoil. When disconnecting irrigation pipe,be sure pipes are drained in a safe manor,not creating an erosion concern.

The production originally started in 2011 which was allowed use by right through the Town. In 2016, a full site plan review process was conducted for a conceptual apartment complex located downslope from the facility which included an approved SWPPP. As part of the storm plan, the work yard was allowed continued use by right but several restrictions were placed on the property limiting the size and scope of the work zone while also requiring the installation of a stormwater management sump practice to provide runoff mitigation and attenuation. Because the apartment complex was never realized, the 2016 restrictions became null and void with the exception that the operation would now be required to carry its own SWPPP. Subcatchment Evaluation: There is one pre-developed(existing)watershed subcatchments (ESC-1) for this site totaling 449,606-SF (10.32-AC). This area is isolated from eastern upland watershed runoff by a road R.O.W. drainage ditch along Scofield Road and a large berm along the southern parcel line Peruville Road. In as much as flow naturally moves in a northwest direction across the site, this prevents influences onto the parcel from the north. General site runoff is directed toward the west over moderately flat slopes where it terminates into an existing l' dry pond (sump) sedimentation basin designed to capture and treat flow. Any surge from the practice outlets harmlessly where it eventually finds its way into the Peruville Road R.O.W. swale below. (DP-1). Because the contractor work yard has been in operation since 2011, this Full Stormwater Pollution Prevention Plan(SWPPP) addresses runoff concerns. As such, the proposed runoff model generally mirrors that of the existing site conditions with the exception that the site has expanded from 2.57-Ac to 4.93-AC through the years. As such the sedimentation basin will need an additional 1' of volume added to ensure that it can continue to meet runoff attenuation requirements from Proposed Subcatchment 1 (PSC-1) Site Control Methods: This project follows DEC design standards on runoff reduction by applying a sedimentation basin to address runoff concerns. Site Soils: There are a two soil types in hydrologic soil groups A and C located across the site. Palmyra gravelly loam (PaQ belongs in the hydrologic soil group A with a well drained permeability range of 0.63 — 6.3 inches per hour. Finally, Kendaia (KnA) is a somewhat poorly drained C type soil with a slow permeability of 0.20 inches per hour. See Appendix 3 for more information. Soils data was obtained from the Tompkins County Soil Survey conducted by the USDA Soil Conservation Service and the on-line Web Soil Survey. 2 1 P a g e Site Topography: The site as a whole has a varied slope of<1% - 5% primarily moving downhill from east to west. Site Watershed: Of the 10.32-acre watershed, the area of disturbance will continue to be approximately 4.93-acres. Flow is channeled across the property into a sedimentation basin. Rainfall: Rainfall data used in the modeling and analysis was taken from www.precipt.net, from the Northeast Regional Climate Center which is an accepted NYSDEC reference. Rainfall data specific to Tompkins County under consideration, for various 24-hour storm events tabled below: RAINFALL DATA STORM 24-HOUR RAINFALL 1-year 2.0 inches 10-year 3.41 inches 100-year 5.85 inches These values were used in modeling for the evaluation of existing and proposed stormwater run-off conditions. 3 1 P a g e RUNOFF REDUCTION VOLUME MANAGEMENT STRATEGY (See Appendix 1 for Worksheet Analyses) 1. Water Quality Volume and Runoff Reduction Stormwater Management Strategy -Reference modeling results and WQvIPRv worksheets which follow this summary: The total site water quality volume for DP-1 is DP-1 WQv= 17,000 cu-ft (0.390) Of this amount, there was no potential for the conservation of natural areas,protection of riparian areas, tree planting, rooftop disconnection, etc. that would lend to a reduction in total WQv. WQv credit=0 cuft(0.00 af) The minimum RRv was based on the following calculation: Soil group for site: A—2.47-AC S = 55% C—2.47-AC S = 30% Minimum RRv: S = 0.43 Impervious Area=4.93-AC Precipitation= 1.0 in Rv=0.95 Minimum Rv= [(P)(Rv)(A)] /12 = ((1.0 * 0.95"/AC X 4.93AC)/12)0.43= 7,225 cuft or, 0.170-acft 2.

Cpv=24 hour extended detention of post-developed 1-year, 24-hour Storm event. The required CPv is a summation of the modeled 1 yr runoff output from each untreated subcatchment(2.0-inch rainfall Tompkins County) after runoff reduction(RRv). 1 yr Cpv 0.193-AF—RRV 0.390-AF=-0.00-AF (-0.00)-CF The Cpv Channel Protection Volume is provided by the basin practices as determined by measuring the storage volume allowed between the floor of the practice at(0.0') and the primary outlet(1.5'), less the amount required for RRV. CPv conditions are met. Overbank Flood (Op)—DPI Qp = Controls the peak discharge from the 10-year storm(3.41-inch rainfall Tompkins County) to 10-year predevelopment rates. Pre-developed max rate = 0.00-CFS, Total Volume = O.000AF (0-CF). The maximum post-developed run-off rate with the bioretention areas in-line is 0- CFS, and the total run-off volume is 0.000-AF (0-CF). The Qp Overbank Flood control criterion is met with the sump area in-line. Extreme Storm (Of)—DP1 Control the peak discharge from the 100-year storm(5.85-inch rainfall Tompkins County) to 100-year predevelopment rates. Safely pass the 100-year storm event. Pre-developed max run-off rate = 6.12-CFS, Total Volume =0.770-AF (33,541-CF). The maximum post-developed run-off rate with the structure inline is 5.64-CFS, and the total run-off volume is 0.946-AF (41,208-CF). The Qf Extreme Storm control criterion is met with the sedimentation basin in-line. 6 1 P a g e METHODOLOGY The methodology used for the hydrologic and hydraulic analysis was obtained from the United States Department of Agriculture (USDA) Soil Conservation Service's (SCS) Technical Release No. 20, as implemented by the application program HydroCAD. HydroCAD, developed by Applied Microcomputer Systems of Chocorua,New Hampshire, is a Computer-Aided-Design(CAD)program for analyzing the hydrologic and hydraulic characteristics of a given watershed and associated stormwater management facilities. It utilizes the latest modeling techniques to predict the consequences of any given storm. HydroCAD has the capability of computing hydrographs and routing flows through pipes, streams and ponds. Hydrographs represent discharge rates characteristic of specified watershed conditions,precipitation and geologic factors. For this analysis, the watershed and drainage system was broken down into a network consisting of three types of components described below: Subcatchment: A relatively homogeneous area of land, which produces a volume and rate of surface run-off unique to that area. Reach: Uniform streams, channels or pipes which convey stormwater from one distinct point to another reach or pond. Pond: Natural or man-made impoundment (ie. pond), which temporarily stores stormwater run-off and empties in a manner determined by its geometry and the hydraulic structure located at its outlet(s). Subcatchments, reaches and ponds are represented by hexagons, squares and triangles, respectively, on the watershed routing diagrams provided with the computations reference modeling results attached. 7 1 P a g e Modelint4 Results Tabled: (See Appendix 2 for actual modeling data) DPI EXISTING EXISTING FLOW CONDITIONS AT DESIGN POINT DPI STORM EVENT PEAK FLOW TOTAL VOLUME CFS AF 1-year 0.00 0.000 10- ear 0.00 0.000 100- ear 6.12 0.770 PROPOSED WITH SEDIMENTATION BASIN IN-LINE PROPOSED FLOW CONDITIONS AT DESIGN POINT(DPI) STORM EVENT PEAK FLOW TOTAL VOLUME CFS AF 1-year 0.00 0.000 10- ear 0.00 0.000 100- ear 5.64 0.946 The run-off rates decrease for the 10 and 100 yr storm events as modeled. 81Page Stage Storalle Tables: BASIN I STAGE-STORAGE TABLE 3P STORM EVENT PEAK PEAK DEPTH STORAGE CF FT WQv 17000 1.03' 1 year (Cpv) 0 0.00, 10 year 0 0.00, 100 year 55,753 2.92' Notes: Bottom of Practice El. = 0.00' 8'x 4'Broad Crested Weir Outlet inv. = 2.50' Top of Embankment Elev. = 3.00' 91Page APPENDIX 1 WATER QUALITY VOLUME/RUNOFF REDUCTION WORKSHEETS 101Page Version 1.6 Total Water Quality Volume Calculation Last Updated: 03/28/2014 WQv(acre-feet) = [(P)(Rv)(A)] /12 Is this project subject to Chapter 10 of the NYS Design Manual (i.e. WQv is equal to post- development 1 year runoff volume)?......................................................................................

They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand,protect,or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions.The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses.The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning,onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nres.usda.gov/wps/portal/ nres/main/soils/health/)and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center(http:// offices.sc.egov.usda.gov/locator/app?agency=nres)or your NRCS State Soil Scientist(http://www.nres.usda.gov/wps/portal/nres/detail/soils/contactus/? cid=nres142p2_053951). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads.Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage; the kinds of crops and native plants; and the kinds of bedrock.They observed and described many soil profiles.A soil profile is the sequence of natural layers, or horizons, in a soil. The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity. Currently,soils are mapped according to the boundaries of major land resource areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically consist of parts of one or more MLRA. The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform,a soil scientist develops a concept,or model,of how they were formed.Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape. Commonly, individual soils on the landscape merge into one another as their characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations, supplemented by an understanding of the soil-vegetation-landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries. Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units). Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil scientists classified and named the soils in the survey area, they compared the 5 Custom Soil Resource Report individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research. The objective of soil mapping is not to delineate pure map unit components; the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements. Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions. Some components may be highly contrasting to the other components of the map unit. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas. Soil scientists make many field observations in the process of producing a soil map. The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist. Observations are made to test and refine the soil- landscape model and predictions and to verify the classification of the soils at specific locations. Once the soil-landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded. These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components. Properties of each soil typically vary from one point to another across the landscape. Observations for map unit components are aggregated to develop ranges of characteristics for the components. The aggregated values are presented. Direct measurements do not exist for every property presented for every map unit component. Values for some properties are estimated from combinations of other properties. While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field-observed characteristics and the soil properties to determine the expected behavior of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management. Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil. Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date. After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and identified each as a specific map unit.Aerial photographs show trees, buildings,fields, roads, and rivers, all of which help in locating boundaries accurately. 6 Soil Map The soil map section includes the soil map for the defined area of interest, a list of soil map units on the map and extent of each map unit, and cartographic symbols displayed on the map. Also presented are various metadata about data used to produce the map, and a description of each soil map unit. 7 Custom Soil Resource Report Soil Map F F N N ip iD n n 380060 380120 380180 380240 380300 380360 380420 380480 380540 380600 380660 42°32'33"N 42°32'33"N All ry i ••�� 'sir '.,-.q�.,�, •._ w y4� - 1 O O O W o— a n 9 42'32'20"N ,.e..J-�._.,..I _r 1.�_ _ R^�` '.l..i�r .n .�.'-•. -Y. �. 42'32'20"N 380060 380120 380180 380240 380300 380360 380420 380480 380540 380600 380660 3 3 5, Map Scale:1:2,910 if printed on A landscape(11"x 8.5")sheet.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils.On the landscape, however,the soils are natural phenomena,and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently,every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management.These are called contrasting,or dissimilar,components.They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially 10 Custom Soil Resource Report where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps.The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha- Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example. 11 Custom Soil Resource Report Tompkins County, New York BgC—Bath and Valois soils, 5 to 15 percent slopes Map Unit Setting National map unit symbol: 2v32c Elevation: 330 to 2,460 feet Mean annual precipitation: 31 to 70 inches Mean annual air temperature: 39 to 52 degrees F Frost-free period: 105 to 180 days Farmland classification: Farmland of statewide importance Map Unit Composition Bath and similar soils: 40 percent Valois and similar soils: 35 percent Minor components: 25 percent Estimates are based on observations, descriptions, and transects of the mapunit.
