The primary purposes for this plan are to: • Identify the SWPPP coordinator and their duties; • Identify any SWPPP team members that will assist in the implementation of the SWPPP during construction; • Define the site characteristics and type of construction; • Identify the receiving bodies of water for the site’s stormwater; • Introduce the site plan for the proposed site; • Identify potential pollutants and sources within the site’s drainage area; • Describe practices that will be implemented for erosion and sediment control; • Describe any temporary or permanent, structural or non-structural, BMPs (Best Management Practices) that will be utilized to manage stormwater quality and quantity. • Create an implementation schedule for the practices within this SWPPP; • Outline a monitoring plan to ensure this plans effectiveness and provide provisions for necessary revisions; and • Describe and provide support for the final stabilization design to ensure water quality and quantity management after the construction of the site. This SWPPP evaluates the existing (pre-construction) and proposed (post- construction) conditions and recommends measures to mitigate stormwater quantity and quality impacts that will result from the proposed site during construction and upon final stabilization. Review of this plan should be in conjunction with the engineering drawings for this project prepared by Tectonic Engineering, Consultants, Geologists, & Land Surveyors, D.P.C. 2.0 PROJECT BACKGROUND 2.1 SITE LOCATION The proposed project site is a solar array, located at 22 Quaker Ridge Boulevard in Queensbury, Warren County, NY. The site is extended north of Quaker Ridge Boulevard and to the west of Queensbury Ave. It is south from the Floyd Bennet Memorial Airport. Stormwater Pollution Prevention Plan CVE Solar Array Town of Queensbury, NY W.O. 10519.08 Page 6 August 2021 2.2 SOILS AND SURFACE COVER The soils of the site consist of Farmington loam with a slope of 0 - 8%, Madalin silt loam, and Oakville loamy fine sand with a slope of 3 - 8%, according to the United States Department of Agriculture (USDA), Soil Conservation Service’s Soil Survey of Orange County, New York. The report for the hydrological group of these soils is considered 64% type A and 36% type D. A copy of the soil survey is included in Appendix C. 2.3 POST DEVELOPMENT SITE CONDITIONS The proposed development results in a solar array taking up more than half of the site. The project site is spread across two parcels, one of which will house the solar panels. A grass surfaced access road is to be implemented for emergency fire access and maintenance. This road will be accessible by branching from Quaker Ridge Boulevard and extend parallel to the west of the array, except for a relatively smaller number of panels on the west side of the parcel. The initial 50 feet of the road leading up to the northern parcel will be porous pavement to accommodate water treatment. Overall impervious land cover will only increase by a slight amount due to the need for equipment/ transformer pads. 3.0 POST-CONSTRUCTION STORMWATER MANAGEMENT The approach to the stormwater management design requires compliance with the New York State Standards for Erosion and Sediment Control and the quantity control requirements included in the New York State Stormwater Management Design Manual (SWDM) and the New York Department of Environmental Conservation (NYSDEC) provided guidance on stormwater regulations related to solar development titled, Solar Panel Construction Stormwater Permitting/SWPPP Guidance dated April 5, 2018. 3.1 EXISTING HYDROLOGY The site does not experience many steep slopes as most of the site is between 0-10% grade. Small areas of the parcel experience slopes up to 15-25% but are not being disturbed. The flow originates primarily from the Eastern region of the site and sheet flows to the East and Northeast in Drainage area A. Drainage Area B’s flow originates to the North and flows South. Flow is never channelized and instead joins into the wetlands to the north and south of the site. The majority of the land cover consists of woods with light underbrush. Stormwater Pollution Prevention Plan CVE Solar Array Town of Queensbury, NY W.O. 10519.08 Page 7 August 2021 The peak runoff flows were calculated for the existing conditions of the site at the discharge points for each drainage area. The methodology utilized for this analysis is based upon the USDA, Soil Conservation Service’s Technical Release No. 20 and Technical Release No. 55, as utilized by the software entitled HydroCAD version 10.00. HydroCAD, developed by Autodesk is a CAD based program for analyzing the hydrology and hydraulics of stormwater runoff. It utilizes the latest techniques to predict the consequences of a given storm event. Hydro CAD has the capability of computing hydrographs (representing discharge rates characteristic of specific watershed conditions, precipitation and geologic factors), combining hydrographs, and routing flows through pipes and detention. For this analysis, the property was analyzed for both the existing and proposed conditions. Rainfall data utilized in the analysis was taken from the data published in the NYSDEC Stormwater Management Design Manual (SWDM). A summary of the parameters results is tabulated below in Table 1. Table 1 : Existing Site Hydrology Summary Drainage Area ID Area Size (acres) CN Tc (min) 1-Year (cfs) 10-Year (cfs) 100-Year (cfs) A 127.97 55 44 0.57 20.27 85.57 B 4.26 39 42 0.00 0.01 0.27 3.2 PROPOSED HYDROLOGY The site, under proposed conditions, will include two arrays of solar panels taking up less than half the property and an access road, originating from Quaker Ridge Boulevard. Infiltration trenches and porous pavement will be implemented to treat stormwater runoff from the equipment pads and the initial stretch of access road. The remaining road is to be considered permeable grass and does not require treatment. The proposed drainage areas “A” will house all of the solar panels. The proposed drainage areas are shown in the Drainage Area Map included in Appendix B. Hydrologic calculations have been performed for each drainage area as described in the prior section and are included in the appendices. A summary of the drainage areas is tabulated below in Table 2. Stormwater Pollution Prevention Plan CVE Solar Array Town of Queensbury, NY W.O. 10519.08 Page 8 August 2021 Table 2: Post Site Hydrology Summary Drainage Area ID Area Size (acres) CN Tc (min) 1-Year (cfs) 10-Year (cfs) 100-Year (cfs) A 127.97 55 44 0.57 20.27 85.57 B 4.26 39 42 0.00 0.01 0.27 3.3 WATER QUALITY/RUNOFF REDUCTION VOLUME The project site was evaluated to meet the New York Department of Environmental Conservation (NYSDEC) provided guidance on stormwater regulations related to solar development titled, Solar Panel Construction Stormwater Permitting/SWPPP Guidance dated April 8, 2018 . A copy of the guidance and a checklist for this project is included in Appendix J. The guidance exempts solar arrays from having to provide post -construction stormwater management practices if the guidance is met. Post-construction stormwater management should be provided for impervious areas. Water quality control, as outlined in the SWDM, was designed to mitigate the impacts of the development of the site resulting from the increase in impervious cover. The project is utilizing a stabilized grass access drive to significantly reduce the amount of impervious cover proposed at the site. The remaining impervious areas are disconnected also mitigating any impacts from them. The required water quality volume was managed at the individual impervious locations: equipment pads and the initial stretch of porous pavement. A summary of the areas is included in Table 3 below. Table 3: Project Area Breakdown Area Type Area (square feet) Total Disturbance 33.3 Existing Impervious 0.00 Proposed Impervious 0.030 The increased impervious of the three transformer pads was mitigated using gravel trenches around the perimeter of the equipment, sized to fully capture and infiltrate the 100-year storm event (see WQv calculations in Appendix D for details). The water quality required to mitigate the total proposed increase in impervious area is summarized in Table 4 below. Stormwater Pollution Prevention Plan CVE Solar Array Town of Queensbury, NY W.O. 10519.08 Page 9 August 2021 Table 4: Equipment Pad/Porous Pavement Stormwater Parameter Value Water Quality Volume Required for Transformer Pads (3 in total) 84 ft3 Transformer Pads (3 in total)-100-year Runoff 385 ft3 Total Volume Provided by Trench Drains 408 ft3 Total Water Quality Required by Porous Pavement 95 ft3 Total Water Quality Provided by Porous Pavement 95 ft3 3.4 WATER QUANTITY CONTROL Water quantity control, as outlined in the SWDM, was designed to mitigate the impacts of the increased runoff from the site resulting from the increase in impervious cover. A hydrologic analysis of the project area was performed to determine if the hydrology of the site is altered from pre to post- development conditions as defined by the SPDES General Per mit GP-0-20-001 (the post- development peak flow rate(s) has increased by more than 5% of the pre - developed condition). Drainage areas “A” and “B” meet these conditions and therefore do not alter the hydrology of the project by definition of the permit. A summary of the pre versus post conditions is summarized in Table 5 below.

These main sources are located within the limits of disturbance and are shown on the Erosion Control Plan. 4.3 SUMMARY OF AVAILABLE STORMWATER SAMPLING DATA There is no existing stormwater sampling data available. 5.0 SOIL EROSION AND SEDIMENT CONTROLS The soil erosion and sediment control measures outlined herein are incorporated into the project site plans. Additionally, a construction schedule and phasing plan to aid in the proper implementation of erosion and sediment controls has been included with the Erosion Control Plan. General measures that will be implemented are as follows: 5.1 GENERAL MEASURES a. There shall be no increase in turbidity that will cause a substantial visible contrast to natural conditions. There shall be no increase in suspended, colloidal and settleable solids that will cause deposition or impair the waters for their best usage. There shall be no residue from oil and floating substances, or visible oil film, or globules of grease. b. Site preparation activities shall be planned to minimize the area and duration of soil disruption. c. All facilities and systems of treatment and control shall be operated and maintained at all times to achieve compliance with the SWPPP. d. In no case shall erodible materials be stockpiled within 25 feet of any wetland, stream or other surface water body. e. All unnecessary removal of healthy trees shall be avoided. Materials shall not be stored nor machinery operated within the drip-line of the trees to remain. f. To facilitate final stabilization, intermediate silt fences/dikes/diversions may be removed upon initial catch of upslope final Stormwater Pollution Prevention Plan CVE Solar Array Town of Queensbury, NY W.O. 10519.08 Page 13 August 2021 seeding/mulching. Perimeter and base of slope silt fences/dikes shall remain in place until final stabilization is achieved to protect offsite discharge potential. g. The site shall be inspected daily by the Contractor and every seven (7) days by the Owner’s Representative as a minimum. They shall insp ect and maintain the integrity and function of all temporary erosion control measures throughout the duration of the development process. h. To assure proper function, siltation barriers shall be maintained in good condition and reinforced, extended, repaired or replaced as necessary. All accumulated sediment shall be removed and contained in appropriate spoil areas. 5.2 TEMPORARY STRUCTURAL MEASURES Temporary structural practices are used during construction to prevent offsite sedimentation. The length of time that temporary practices are functional varies from project to project, since the sediment control strategy may change as construction activity progresses. Runoff control measures should be the first items constructed when grading begins, and be completely functional before downslope land disturbance takes place. Only after the runoff control structures are operational and sediment control measures are in place, should clearing and grading on the rest of the construction site begin. a. Silt Fence - A temporary barrier of geotextile fabric installed on the contours across a slope used to intercept sediment laden runoff from small drainage areas of disturbed soil. The purpose of a silt fence is to reduce runoff velocity and effect deposition of transported sed iment load. Limits imposed by ultraviolet stability of the fabric will dictate the maximum period the silt fence may be used (approximately one year). b. Straw Bale Dike - A temporary barrier of straw, or similar material, used to intercept sediment laden runoff from small drainage areas of disturbed soil. The purpose of a bale dike is to reduce runoff velocity and effect deposition of the transported sediment load. Straw bale dikes have an estimated design life of three (3) months. c. Stabilization Construction Entrance - A stabilized pad of aggregate underlain with geotextile 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 stabilized Stormwater Pollution Prevention Plan CVE Solar Array Town of Queensbury, NY W.O. 10519.08 Page 14 August 2021 construction entrance is to reduce or eliminate the tracking of sediment onto public rights-of way or streets. d. Concrete Truck Washout - A temporary excavated or above ground lined constructed pit where concrete truck mixers and equipment can be washed after their loads have been discharged, to prevent highly alkaline runoff from entering storm drainage systems or leaching into soil. The washout is required to have a minimum depth of 2-feet and 8-feet by 8- feet dimensions. The location of the washout should be sufficiently (minimum of 100 feet) from drainage structures and close to the gravel access drive. e. Dust Control - The control of dust resulting from land-disturbing activities. The purpose of dust control is to prevent surface and air movement of dust from disturbed soil surfaces that may cause off-site damage, health hazards, and traffic safety problems. f. Water Bars - A permanent or temporary berm, ridge and channel, a structural channel, or flow defector, constructed diagonally across a sloping road or utility right of way on an unpaved surface subject to erosion to limit the accumulation of the erosive velocity of water by diverting surface runoff at pre-designed intervals. 5.3 VEGETATIVE MEASURES a. As much as practical, existing vegetation shall be preserved. Following the completion of construction activities in any portion of the site, permanent vegetation shall be established on all exposed soils. b. Permanent vegetative cover: Immediately following the completion of construction activity in any portion of the site, permanent vegetation shall be established on all exposed soils. c. Washouts shall be immediately repaired, re-seeded and protected from further erosion. d. An adequate seedbed shall be prepared by scarifying soil and removing surface debris and obstacles within the disturbed area to a depth of 4 inches. e. All landscaped/grassed areas will be seeded and mulched in a two-step hydraulic process to promote growth as soon as possible. f. All seeding shall be performed using hydroseeding. Hydroseeding slurry shall be comprised of a homogeneous mix of seed and fertilizer in Stormwater Pollution Prevention Plan CVE Solar Array Town of Queensbury, NY W.O. 10519.08 Page 15 August 2021 water. Various specified seed mixes shall be independently mixed and applied. g. All disturbed areas shall be stabilized subsequent to seeding by applying 2 tons of straw mulch per acre. Straw mulch shall be anchored by applying 750 lbs of wood fiber mulch per acre with a hydroseeder. Hydromulching slurry shall be comprised of a homogeneous mix of non- asphaltic tackifier and fiber mulch in water. h. Deep ripping and Decompaction are key factors which help in restoring soil pore space and permeability for water infiltration. Conversely, the physical actions of cut-and-fill work, land grading, the ongoing movement of construction equipment and the transport of building materials throughout a site alter the architecture and structure of the soil, resulting in: the mixing of layers (horizons) of soil materials, compression of those materials and diminished soil porosity which, if left unchecked, severely impairs the soil’s water holding capac ity and vertical drainage (rainfall infiltration), from the surface downward. The two-phase practice of 1) “Deep Ripping;” and 2) “Decompaction” (deep subsoiling), of the soil material as a step in the cleanup and restoration/landscaping of a construction site, helps mitigate the physically induced impacts of soil compression; i.e.: soil compaction or the substantial increase in the bulk density of the soil material. 5.4 SWPPP MEASURES a. The owner and their contractor and sub-contractors shall modify the on-site SWPPP. b. When there is a significant change in design, construction, operation, or maintenance which may have a significant effect on the potential for discharge of pollutant to the waters of the United States and which has not otherwise been addressed in the SWPPP. c. If the SWPPP proves to be ineffective in eliminating or significantly minimizing pollutants identified in the SWPPP, or achieving the general objectives of controlling pollutants in stormwater discharged from construction activities. d. To identify any contractor or sub-contractor that will implement any measure of the SWPPP. e. All contractors and sub-contractors identified in the SWPPP as outlined above shall sign a copy of the Certification Statement before undertaking any construction activity at the site identified in the SWPPP. Stormwater Pollution Prevention Plan CVE Solar Array Town of Queensbury, NY W.O. 10519.08 Page 16 August 2021 f. The developer/contractor or his builder shall have the site inspected and a log kept on site. The documents must be maintained in a secure location, such as a job trailer, on-site construction office, or a mailbox with lock; that is accessible during normal working hours to an individual performing a compliance inspection. To effectively control wind erosion, water shall be applied to all exposed soils as necessary of the project site as designed. 6.0 PROJECT PHASING AND CONSTRUCTION SEQUENCE 6.1 PROJECT PHASING The project has been broken up into phases in order to maintain the maximum disturbance of 5 acres at one time. Table 7: Project Phasing and Sequencing Phase Phase Construction Sequence 11 Install perimeter controls around access road. maintain until construction is complete and final stabilization is achieved. 21 Phase 2 is divided into the subphases below: Subphase A: Construct porous pavement access road with water bars with proposed grades as shown on the plans.

Maintain staging area as needed. 2 Tree clearing operations for solar may begin during phase 2. Until phases 2-4A are complete, tree clearing shall not include stump removal. 3 Maintain opening in fence at locations of underground electric wiring in phase 4D. 6.2 OVERALL CONSTRUCTION SEQUENCE Sequence of Construction Activities: The Contractor’s work schedule and methods shall be consistent with the SWPPP or amended SWPPP. Once approved, the progress schedule shall become a part of the SWPPP. The following list is a suggested sequence of major construction activities for the project to meet the NYSDEC erosion control requirements: 1. All approvals and permits shall be secured. 2. A pre-construction meeting with owner, owner's representative, municipal representative and contractor present will be held. 3. Construction entrance, silt fence, straw bale dike, storm drain inlet protection, construction fence and other temporary erosion control measures will be installed prior to any construction including clearing, grubbing, and demolition of the site in accordance with the NYS Standards and Specifications for Erosion Control August 20 16. 4. Install provisions for protection of existing facilities where indicated on the plans and details 5. Disturbance shall be limited less than 1 acre maximum. All non-active disturbed areas shall receive temporary or permanent stabilization. Non-active disturbed areas shall not remain fallow for longer than 14 days without being stabilized. 6. Any borrow or waste pits located on or off-site must immediately receive temporary stabilization, shall not be left unstabilized, and be maintained per the requirement of the SWPPP for this project. 7. Upon construction improvements, final grading will begin. Stormwater Pollution Prevention Plan CVE Solar Array Town of Queensbury, NY W.O. 10519.08 Page 18 August 2021 8. Decompact access and storage/stockpile areas. 9. All landscaped/grassed areas will be seeded and mulched in a two- step hydraulic process to promote growth as soon as possible. 10. Upon stabilization, all temporary measures will be removed. 11. All drainage lines are to be flushed clean of all silt and sediment after all construction disturbance has been stabilized. Remove all silt from permanent storm water control structures. 12. Remove all silt and sediment from site. 13. All debris, silt, and other obstructions are to be removed from the end of the drainage structures after all on site work is complete and all disturbed areas have been stabilized. 7.0 NONSTRUCTURAL BMPS There are nonstructural BMPs that are included as parts of this plan to prevent the introduction of pollutants into stormwater. 7.1 GOOD HOUSEKEEPING All exposed areas of the site with the potential for stormwater pollutants must be kept clean and orderly. Specific areas of concern for this site include, but are not limited to: storage areas, fueling areas, and equipment storage and cleaning areas. A schedule for Good Housekeeping practices should be created prior to construction and followed and altered as necessary throughout the project. 7.2 MINIMIZING EXPOSURE The exposure of pollutants to rain, ice, snow, and snowmelt should be minimized by utilizing practices to limit such exposure. For example, when possible, water resistant coverings should be used to minimize exposure. 7.3 DUST CONTROL Dust Control measures help to prevent surface and air movement of dust from disturbed soil surfaces that may cause off-site damage, health hazards, and traffic safety problems. Dust Control measures should be installed on construction roads, access points, and other disturbed, areas subject to surface dust movement and dust blowing where off -site damage may occur if dust is not controlled. Stormwater Pollution Prevention Plan CVE Solar Array Town of Queensbury, NY W.O. 10519.08 Page 19 August 2021 Water quality must be considered when materials are selected for dust control. Where there is a potential for the material to wash off to a stream , ingredient information must be provided to the local permitting authority. 7.4 NON-DRIVING AREAS These areas use products and materials applied or placed on soil surfaces to prevent airborne migration of soil particles. a. Vegetative Cover- For disturbed areas not subject to traffic, vegetation provides the most practical method of dust control b. Mulch (including gravel mulch) – Mulch offers a fast effective means of controlling dust. This can also include rolled erosion control blankets. 7.5 DRIVING AREAS These areas utilize water, polymer emulsions, and barriers to prevent dust movement from the traffic surface into the air. Provision shall be made to control the amount of airborne dust released off site from construction operations, by wetting the construction mat erial as necessary, provided wetting will not damage utility infrastructure or create any safety hazards. All construction material shall be sufficiently wetted to prevent dust from becoming airborne before loading into trucks, vehicles or other containers. During transport, such material shall be enclosed or covered to prevent dust dispersion. Trucks and other vehicles used to transport particulate matter shall be covered and any particulate matter kept on site shall be sufficiently wetted or stored to prevent particulate matter from becoming airborne. 7.6 SPILL PREVENTION AND RESPONSE PROCEDURES All potential pollutants other than sediment will be handled and disposed of in a manner that does not cause contamination of stormwater. Non-sediment pollutants that may be present during construction activities have been identified in Section 4.0 of this report. These materials, and other materials used during construction with the potential to impact stormwater, will be stored, managed, used, and disposed of in a manner that minimizes the potential for release into the environment. Emergency contacts for the project will be posted at the project office, and are included at the end of this section. Stormwater Pollution Prevention Plan CVE Solar Array Town of Queensbury, NY W.O. 10519.08 Page 20 August 2021 7.7 GENERAL MATERIAL AND HANDLING PRACTICES The following general practices will be used throughout construction to reduce the potential for spills. • Potential pollutants will be stored and used in a manner consistent with the manufacturer’s instructions in a secure location. To the extent practicable, material storage areas should not be located near storm drain inlets and should be equipped with covers, roofs, or secondary containment as needed to prevent stormwater from contacting stored materials. Chemicals that are not compatible shall be stored in segregated areas so that spilled materials cannot combine and react. • Materials disposal will be in accordance with the manufacturer’s instructions and applicable local, state, and federal regulations. • Materials no longer required for construction will be removed from the site as soon as practicable. • Adequate garbage, construction waste, and sanitary waste handling and disposal facilities will be provided to the extent necessary to keep the site clear of obstruction and BMPs clear and functional. 7.8 SPECIFIC MATERIAL AND HANDLING PRACTICES All pollutants, including waste materials and demolition debris, that occur on - site during construction will be handled in a way that does not contaminate stormwater. a. All chemicals including liquid products, petroleum products, water treatment chemicals, and wastes stored on site will be covered and contained and protected from vandalism. b. Maintenance and repair of all equipment and vehicles involving oil changes, hydraulic system drain down, de-greasing operations, fuel tank drain down and removal, and other activities which may result in the accidental release of contaminants, will be conducted under cover during wet weather and on an impervious surface to prevent the release of contaminants onto the ground. Materials spilled during maintenance operations will be cleaned up immediately and properly disposed of. c. Equipment wash wastewater will be settled and discharged on site by infiltration in a designated area setback from the wetlands and controlled by erosion measures. d. Application of agricultural chemicals, including fertilizers and pesticides, will be conducted in a manner and at application rates that Stormwater Pollution Prevention Plan CVE Solar Array Town of Queensbury, NY W.O. 10519.08 Page 21 August 2021 will not result in loss of chemical to stormwater runoff. Manufacturers’ recommendations will be followed for application rates and procedures. e. pH-modifying sources will be managed to prevent contamination of runoff and stormwater collected on site. The most common sources of pH-modifying materials are bulk cement, cement kiln dust (CKD), fly ash, new concrete washing and curing waters, waste streams generated from concrete grinding and sawing, exposed aggregate processes, and concrete pumping and mixer washout waters. 7.9 SPILL RESPONSE The primary objective in responding to a spill is to quickly contain the material(s) and prevent or minimize their migration into stormwater runoff and conveyance systems. If the release has impacted on-site stormwater, it is critical to contain the released materials on site and prevent their release into receiving waters. a. If a spill of pollutants threatens stormwater at the site, the spill response procedures outlined below must be implemented in a timely manner to prevent the release of pollutants. b. The site superintendent will be notified immediately when a spill, or the threat of a spill, is observed. The superintendent will assess the situation and determine the appropriate response. c. If spills represent an imminent threat of escaping facilities and entering the receiving waters, facility personnel will respond immediately to contain the release and notify the superintendent after the situation has been stabilized. d. Spill kits containing materials and equipment for spill response and cleanup will be maintained at the site. Each spill kit may contain: e. Oil absorbent pads (one bale) f. Oil absorbent booms (40 feet) g. 55-gallon drums (2) h. 9-mil plastic bags (10) i. Personal protective equipment including gloves and goggles j. If an oily sheen is observed on surface water (e.g., settling ponds, detention pond, and swales), absorbent pads and/or booms will be applied to contain and remove the oil. The source of the oil sheen will also be identified and removed or repaired as necessary to prevent further releases. Stormwater Pollution Prevention Plan CVE Solar Array Town of Queensbury, NY W.O. 10519.08 Page 22 August 2021 k. The site superintendent, or his designee, will be responsible for completing the spill reporting form and for reporting the spill to the appropriate state or local agency. l. Facility personnel with primary responsibility for spill response and cleanup will receive training from the site superintendent. This training will include identifying the locati on of spill kits and other spill response equipment and the use of spill response materials. m. Spill response equipment will be inspected and maintained as necessary to replace any materials used in spill response activities. 7.10 NOTIFICATION In the event of a spill, make the appropriate notification(s) consistent with the following procedures: a. Any spill of oil which a) violates water quality standards, b) produces a “sheen” on a surface water, or c) causes a sludge or emulsion must be reported immediately by telephone to the National Response Center Hotline at (800) 424-8802. b. Any oil, hazardous substance, or hazardous waste release which exceeds the reportable quantity must be reported immediately by telephone to the National Response Center Hotline at (800) 424-8802. c.

New York administers the approved State Pollutant Discharge Elimination System (SPDES) program with permits issued in accordance with the New York State Environmental Conservation Law (ECL) Article 17, Titles 7, 8 and Article 70. An owner or operator of a construction activity that is eligible for coverage under this permit must obtain coverage prior to the commencement of construction activity. Activities that fit the definition of “construction activity”, as defined under 40 CFR 122.26(b)(14)(x), (15)(i), and (15)(ii), constitute construction of a point source and therefore, pursuant to ECL section 17-0505 and 17-0701, the owner or operator must have coverage under a SPDES permit prior to commencing construction activity. The owner or operator cannot wait until there is an actual discharge from the construction site to obtain permit coverage. *Note: The italicized words/phrases within this permit are defined in Appendix A.

PERMIT COVERAGE AND LIMITATIONS A. Permit Application This permit authorizes stormwater discharges to surface waters of the State from the following construction activities identified within 40 CFR Parts 122.26(b)(14)(x), 122.26(b)(15)(i) and 122.26(b)(15)(ii), provided all of the eligibility provisions of this permit are met: 1. Construction activities involving soil disturbances of one (1) or more acres; including disturbances of less than one acre that are part of a larger common plan of development or sale that will ultimately disturb one or more acres of land; excluding routine maintenance activity that is performed to maintain the original line and grade, hydraulic capacity or original purpose of a facility; 2. Construction activities involving soil disturbances of less than one (1) acre where the Department has determined that a SPDES permit is required for stormwater discharges based on the potential for contribution to a violation of a water quality standard or for significant contribution of pollutants to surface waters of the State. 3. Construction activities located in the watershed(s) identified in Appendix D that involve soil disturbances between five thousand (5,000) square feet and one (1) acre of land. B. Effluent Limitations Applicable to Discharges from Construction Activities Discharges authorized by this permit must achieve, at a minimum, the effluent limitations in Part I.B.1. (a) – (f) of this permit. These limitations represent the degree of effluent reduction attainable by the application of best practicable technology currently available. 1. Erosion and Sediment Control Requirements - The owner or operator must select, design, install, implement and maintain control measures to minimize the discharge of pollutants and prevent a violation of the water quality standards. The selection, design, installation, implementation, and maintenance of these control measures must meet the non-numeric effluent limitations in Part I.B.1.(a) – (f) of this permit and be in accordance with the New York State Standards and Specifications for Erosion and Sediment Control, dated November 2016, using sound engineering judgment. Where control measures are not designed in conformance with the design criteria included in the technical standard, the owner or operator must include in the Stormwater Pollution Prevention Plan (“SWPPP”) the reason(s) for the (Part I.B.1) 2 deviation or alternative design and provide information which demonstrates that the deviation or alternative design is equivalent to the technical standard. a. Erosion and Sediment Controls. Design, install and maintain effective erosion and sediment controls to minimize the discharge of pollutants and prevent a violation of the water quality standards. At a minimum, such controls must be designed, installed and maintained to: (i) Minimize soil erosion through application of runoff control and soil stabilization control measure to minimize pollutant discharges; (ii) Control stormwater discharges, including both peak flowrates and total stormwater volume, to minimize channel and streambank erosion and scour in the immediate vicinity of the discharge points; (iii) Minimize the amount of soil exposed during construction activity; (iv) Minimize the disturbance of steep slopes; (v) Minimize sediment discharges from the site; (vi) Provide and maintain natural buffers around surface waters, direct stormwater to vegetated areas and maximize stormwater infiltration to reduce pollutant discharges, unless infeasible; (vii) Minimize soil compaction. Minimizing soil compaction is not required where the intended function of a specific area of the site dictates that it be compacted; (viii) Unless infeasible, preserve a sufficient amount of topsoil to complete soil restoration and establish a uniform, dense vegetative cover; and (ix) Minimize dust. On areas of exposed soil, minimize dust through the appropriate application of water or other dust suppression techniques to control the generation of pollutants that could be discharged from the site. b. Soil Stabilization. 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. For construction sites that directly discharge to one of the 303(d) segments (Part I.B.1.b) 3 listed in Appendix E or is located in one of the watersheds listed in Appendix C, the application of soil stabilization measures must be initiated by the end of the next business day and completed within seven (7) days from the date the current soil disturbance activity ceased. See Appendix A for definition of Temporarily Ceased. c. Dewatering. Discharges from dewatering activities, including discharges from dewatering of trenches and excavations, must be managed by appropriate control measures. d. Pollution Prevention Measures. Design, install, implement, and maintain effective pollution prevention measures to minimize the discharge of pollutants and prevent a violation of the water quality standards. At a minimum, such measures must be designed, installed, implemented and maintained to: (i) Minimize the discharge of pollutants from equipment and vehicle washing, wheel wash water, and other wash waters. This applies to washing operations that use clean water only. Soaps, detergents and solvents cannot be used; (ii) Minimize the exposure of building materials, building products, construction wastes, trash, landscape materials, fertilizers, pesticides, herbicides, detergents, sanitary waste, hazardous and toxic waste, and other materials present on the site to precipitation and to stormwater. Minimization of exposure is not required in cases where the exposure to precipitation and to stormwater will not result in a discharge of pollutants, or where exposure of a specific material or product poses little risk of stormwater contamination (such as final products and materials intended for outdoor use) ; and (iii) Prevent the discharge of pollutants from spills and leaks and implement chemical spill and leak prevention and response procedures. e. Prohibited Discharges. The following discharges are prohibited: (i) Wastewater from washout of concrete; (ii) Wastewater from washout and cleanout of stucco, paint, form release oils, curing compounds and other construction materials; (Part I.B.1.e.iii) 4 (iii) Fuels, oils, or other pollutants used in vehicle and equipment operation and maintenance; (iv) Soaps or solvents used in vehicle and equipment washing; and (v) Toxic or hazardous substances from a spill or other release. f. Surface Outlets. When discharging from basins and impoundments, the outlets shall be designed, constructed and maintained in such a manner that sediment does not leave the basin or impoundment and that erosion at or below the outlet does not occur. C. Post-construction Stormwater Management Practice Requirements 1. The owner or operator of a construction activity that requires post-construction stormwater management practices pursuant to Part III.C. of this permit must select, design, install, and maintain the practices to meet the performance criteria in the New York State Stormwater Management Design Manual (“Design Manual”), dated January 2015, using sound engineering judgment. Where post-construction stormwater management practices (“SMPs”) are not designed in conformance with the performance criteria in the Design Manual, the owner or operator must include in the SWPPP the reason(s) for the deviation or alternative design and provide information which demonstrates that the deviation or alternative design is equivalent to the technical standard. 2. The owner or operator of a construction activity that requires post-construction stormwater management practices pursuant to Part III.C. of this permit must design the practices to meet the applicable sizing criteria in Part I.C.2.a., b., c. or d. of this permit. a. Sizing Criteria for New Development (i) Runoff Reduction Volume (“RRv”): Reduce the total Water Quality Volume (“WQv”) by application of RR techniques and standard SMPs with RRv capacity. The total WQv shall be calculated in accordance with the criteria in Section 4.2 of the Design Manual. (ii) Minimum RRv and Treatment of Remaining Total WQv: Construction activities that cannot meet the criteria in Part I.C.2.a.(i) of this permit due to site limitations shall direct runoff from all newly constructed impervious areas to a RR technique or standard SMP with RRv capacity unless infeasible. The specific site limitations that prevent the reduction of 100% of the WQv shall be documented in the SWPPP. (Part I.C.2.a.ii) 5 For each impervious area that is not directed to a RR technique or standard SMP with RRv capacity, the SWPPP must include documentation which demonstrates that all options were considered and for each option explains why it is considered infeasible. In no case shall the runoff reduction achieved from the newly constructed impervious areas be less than the Minimum RRv as calculated using the criteria in Section 4.3 of the Design Manual. The remaining portion of the total WQv that cannot be reduced shal l be treated by application of standard SMPs. (iii) Channel Protection Volume (“Cpv”): Provide 24 hour extended detention of the post-developed 1-year, 24-hour storm event; remaining after runoff reduction. The Cpv requirement does not apply when: (1) Reduction of the entire Cpv is achieved by application of runoff reduction techniques or infiltration systems, or (2) The site discharges directly to tidal waters, or fifth order or larger streams. (iv) Overbank Flood Control Criteria (“Qp”): Requires storage to attenuate the post-development 10-year, 24-hour peak discharge rate (Qp) to predevelopment rates. The Qp requirement does not apply when: (1) the site discharges directly to tidal waters or fifth order or larger streams, or (2) A downstream analysis reveals that overbank control is not required. (v) Extreme Flood Control Criteria (“Qf”): Requires storage to attenuate the post-development 100-year, 24-hour peak discharge rate (Qf) to predevelopment rates. The Qf requirement does not apply when: (1) the site discharges directly to tidal waters or fifth order or larger streams, or (2) A downstream analysis reveals that overbank control is not required. b. Sizing Criteria for New Development in Enhanced Phosphorus Removal Watershed (i) Runoff Reduction Volume (RRv): Reduce the total Water Quality Volume (WQv) by application of RR techniques and standard SMPs with RRv capacity. The total WQv is the runoff volume from the 1 -year, 24 hour design storm over the post-developed watershed and shall be (Part I.C.2.b.i) 6 calculated in accordance with the criteria in Section 10.3 of the Design Manual. (ii) Minimum RRv and Treatment of Remaining Total WQv: Construction activities that cannot meet the criteria in Part I.C.2.b.(i) of this permit due to site limitations shall direct runoff from all newly constructed impervious areas to a RR technique or standard SMP with RRv capacity unless infeasible. The specific site limitations that prevent the reduction of 100% of the WQv shall be documented in the SWPPP. For each impervious area that is not directed to a RR technique or standard SMP with RRv capacity, the SWPPP must include documentation which demonstrates that all options were considered and for each option explains why it is considered infeasible. In no case shall the runoff reduction achieved from the newly constructed impervious areas be less than the Minimum RRv as calculated using the criteria in Section 10.3 of the Design Manual. The remaining portion of the total WQv that cannot be reduced shall be treated by application of standard SMPs. (iii) Channel Protection Volume (Cpv): Provide 24 hour extended detention of the post-developed 1-year, 24-hour storm event; remaining after runoff reduction. The Cpv requirement does not apply when: (1) Reduction of the entire Cpv is achieved by application of runoff reduction techniques or infiltration systems, or (2) The site discharges directly to tidal waters, or fifth order or larger streams. (iv) Overbank Flood Control Criteria (Qp): Requires storage to attenuate the post-development 10-year, 24-hour peak discharge rate (Qp) to predevelopment rates. The Qp requirement does not apply when: (1) the site discharges directly to tidal waters or fifth order or larger streams, or (2) A downstream analysis reveals that overbank control is not required. (v) Extreme Flood Control Criteria (Qf): Requires storage to attenuate the post-development 100-year, 24-hour peak discharge rate (Qf) to predevelopment rates. The Qf requirement does not apply when: (1) the site discharges directly to tidal waters or fifth order or larger streams, or (2) A downstream analysis reveals that overbank control is not required. (Part I.C.2.c) 7 c. Sizing Criteria for Redevelopment Activity (i) Water Quality Volume (WQv): The WQv treatment objective for redevelopment activity shall be addressed by one of the following options. Redevelopment activities located in an Enhanced Phosphorus Removal Watershed (see Part III.B.3. and Appendix C of this permit) shall calculate the WQv in accordance with Section 10.3 of the Design Manual. All other redevelopment activities shall calculate the WQv in accordance with Section 4.2 of the Design Manual. (1) Reduce the existing impervious cover by a minimum of 25% of the total disturbed, impervious area. The Soil Restoration criteria in Section 5.1.6 of the Design Manual must be applied to all newly created pervious areas, or (2) Capture and treat a minimum of 25% of the WQv from the disturbed, impervious area by the application of standard SMPs; or reduce 25% of the WQv from the disturbed, impervious area by the application of RR techniques or standard SMPs with RRv capacity., or (3) Capture and treat a minimum of 75% of the WQv from the disturbed, impervious area as well as any additional runoff from tributary areas by application of the alternative practices discussed in Sections 9.3 and 9.4 of the Design Manual., or (4) Application of a combination of 1, 2 and 3 above that provide a weighted average of at least two of the above methods. Application of this method shall be in accordance with the criteria in Section 9.2.1(B) (IV) of the Design Manual. If there is an existing post-construction stormwater management practice located on the site that captures and treats runoff from the impervious area that is being disturbed, the WQv treatment option selected must, at a minimum, provide treatment equal to the treatment that was being provided by the existing practice(s) if that treatment is greater than the treatment required by options 1 – 4 above. (ii) Channel Protection Volume (Cpv): Not required if there are n o changes to hydrology that increase the discharge rate from the project site. (iii) Overbank Flood Control Criteria (Qp): Not required if there are no changes to hydrology that increase the discharge rate from the project site. (iv) Extreme Flood Control Criteria (Qf): Not required if there are no changes to hydrology that increase the discharge rate from the project site (Part I.C.2.d) 8 d. Sizing Criteria for Combination of Redevelopment Activity and New Development Construction projects that include both New Development and Redevelopment Activity shall provide post-construction stormwater management controls that meet the sizing criteria calculated as an aggregate of the Sizing Criteria in Part I.C.2.a. or b. of this permit for the New Development portion of the project and Part I.C.2.c of this permit for Redevelopment Activity portion of the project. D. Maintaining Water Quality The Department expects that compliance with the conditions of this permit will control discharges necessary to meet applicable water quality standards. It shall be a violation of the ECL for any discharge to either cause or contribute to a violation of water quality standards as contained in Parts 700 through 705 of Title 6 of the Official Comp ilation of Codes, Rules and Regulations of the State of New York, such as: 1. There shall be no increase in turbidity that will cause a substantial visible contrast to natural conditions; 2. There shall be no increase in suspended, colloidal or settleable solids that will cause deposition or impair the waters for their best usages; and 3. There shall be no residue from oil and floating substances, nor visible oil film, nor globules of grease. If there is evidence indicating that the stormwater discharges authorized by this permit are causing, have the reasonable potential to cause, or are contributing to a violation of the water quality standards; the owner or operator must take appropriate corrective action in accordance with Part IV.C.5. of this general permit and document in accordance with Part IV.C.4. of this general permit. To address the water quality standard violation the owner or operator may need to provide additional information, include and implement appropriate controls in the SWPPP to correct the problem, or obtain an individual SPDES permit. If there is evidence indicating that despite compliance with the terms and conditions of this general permit it is demonstrated that the stormwater discharges authorized by this permit are causing or contributing to a violation of water quality standards, or if the Department determines that a modification of the permit is necessary to prevent a violation of water quality standards, the authorized discharges will no longer be eligible for coverage under this permit. The Department may require the owner or operator to obtain an individual SPDES permit to continue discharging. (Part I.E) 9 E. Eligibility Under This General Permit 1. This permit may authorize all discharges of stormwater from construction activity to surface waters of the State and groundwaters except for ineligible discharges identified under subparagraph F. of this Part. 2. Except for non-stormwater discharges explicitly listed in the next paragraph, this permit only authorizes stormwater discharges; including stormwater runoff, snowmelt runoff, and surface runoff and drainage, from construction activities. 3. Notwithstanding paragraphs E.1 and E.2 above, the following non-stormwater discharges are authorized by this permit: those listed in 6 NYCRR 750- 1.2(a)(29)(vi), with the following exception: “Discharges from firefighting activities are authorized only when the firefighting activities are emergencies/unplanned”; waters to which other components have not been added that are used to control dust in accordance with the SWPPP ; and uncontaminated discharges from construction site de-watering operations.

The existence of site limitations shall be confirmed and documented using actual field testing (i.e. test pits, soil borings, and infiltration test) or using information from the most current United States Department of Agriculture (USDA) Soil Survey for the County where the project is located. Sizing Criteria – means the criteria included in Part I.C.2 of the permit that are used to size post-construction stormwater management control practices. The criteria include; Water Quality Volume (WQv), Runoff Reduction Volume (RRv), Channel Protection Volume (Cpv), Overbank Flood (Qp), and Extreme Flood (Qf). State Pollutant Discharge Elimination System (SPDES) - means the system established pursuant to Article 17 of the ECL and 6 NYCRR Part 750 for issuance of permits authorizing discharges to the waters of the state.

Streambank – as used in this permit, means the terrain alongside the bed of a creek or stream. The bank consists of the sides of the channel, between which the flow is confined. Stormwater Pollution Prevention Plan (SWPPP) – means a project specific report, including construction drawings, that among other things: describes the construction activity(ies), identifies the potential sources of pollution at the construction site; describes and shows the stormwater controls that will be used to control the pollutants (i.e. erosion and sediment controls; for many projects, includes post-construction stormwater management controls); and identifies procedures the owner or operator will implement to comply with the terms and conditions of the permit. See Part III of the permit for a complete description of the information that must be included in the SWPPP. Surface Waters of the State - shall be construed to include lakes, bays, sounds, ponds, impounding reservoirs, springs, rivers, streams, creeks, estuaries, marshes, inlets, canals, the Atlantic ocean within the territorial seas of the state of New York and all other bodies of surface water, natural or artificial, inland or coastal, fresh or salt, public or private (except those private waters that do not combine or effect a junction with natural surface waters), which are wholly or partially within or bordering the state or within its jurisdiction. Waters of the state are further defined in 6 NYCRR Parts 800 to 941. Temporarily Ceased – means that an existing disturbed area will not be disturbed again within 14 calendar days of the previous soil disturbance. Temporary Stabilization - means that exposed soil has been covered with material(s) as set forth in the technical standard, New York Standards and Specifications for Erosion and Sediment Control, to prevent the exposed soil from eroding. The materials can include, but are not limited to, mulch, seed and mulch, and erosion control mats (e.g. jute twisted yarn, excelsior wood fiber mats). Total Maximum Daily Loads (TMDLs) - A TMDL is the sum of the allowable loads of a single pollutant from all contributing point and nonpoint sources. It is a calculation of the maximum amount of a pollutant that a waterbody can receive on a daily basis and still meet water quality standards, and an allocation of that amount to the pollutant's sources. A TMDL stipulates wasteload allocations (WLAs) for point source discharges, load allocations (LAs) for nonpoint sources, and a margin of safety (MOS). Trained Contractor - means an employee from the contracting (construction) company, identified in Part III.A.6., that has received four (4) hours of Department endorsed Appendix A 47 training in proper erosion and sediment control principles from a Soil and Water Conservation District, or other Department endorsed entity. After receiving the initial training, the trained contractor shall receive four (4) hours of training every three (3) years. It can also mean an employee from the contracting (construction) company, identified in Part III.A.6., that meets the qualified inspector qualifications (e.g. licensed Professional Engineer, Certified Professional in Erosion and Sediment Control (CPESC), Registered Landscape Architect, New York State Erosion and Sediment Control Certificate Program holder, or someone working under the direct supervision of, and at the same company as, the licensed Professional Engineer or Registered Landscape Architect, provided they have received four (4) hours of Department endorsed training in proper erosion and sediment control principles from a Soil and Water Conservation District, or other Department endorsed entity). The trained contractor is responsible for the day to day implementation of the SWPPP. Uniform Procedures Act (UPA) Permit - means a permit required under 6 NYCRR Part 621 of the Environmental Conservation Law (ECL), Article 70. Water Quality Standard - means such measures of purity or quality for any waters in relation to their reasonable and necessary use as promulgated in 6 NYCRR Part 700 et seq. 48 APPENDIX B – Required SWPPP Components by Project Type Table 1 Construction Activities that Require the Preparation of a SWPPP That Only Includes Erosion and Sediment Controls The following construction activities that involve soil disturbances of one (1) or more acres of land, but less than five (5) acres: • Single family home not located in one of the watersheds listed in Appendix C or not directly discharging to one of the 303(d) segments listed in Appendix E • Single family residential subdivisions with 25% or less impervious cover at total site build-out and not located in one of the watersheds listed in Appendix C and not directly discharging to one of the 303(d) segments listed in Appendix E • Construction of a barn or other agricultural building, silo, stock yard or pen.

Conditions Where Practice Applies Washout facilities shall be provided for every project where concrete will be poured or otherwise formed on the site. This facility will receive highly alkaline wash water from the cleaning of chutes, mixers, hoppers, vibrators, placing equipment, trowels, and screeds. Under no circumstances will wash water from these operations be allowed to infiltrate into the soil or enter surface waters. Design Criteria Capacity: The washout facility should be sized to contain solids, wash water, and rainfall and sized to allow for the evaporation of the wash water and rainfall. Wash water shall be estimated at 7 gallons per chute and 50 gallons per hopper of the concrete pump truck and/or discharging drum. The minimum size shall be 8 feet by 8 feet at the bottom and 2 feet deep. If excavated, the side slopes shall be 2 horizontal to 1 vertical. Location: Locate the facility a minimum of 100 feet from drainage swales, storm drain inlets, wetlands, streams and other surface waters. Prevent surface water from entering the structure except for the access road. Provide appropriate access with a gravel access road sloped down to the structure. Signs shall be placed to direct drivers to the facility after their load is discharged. Liner: All washout facilities will be lined to prevent leaching of liquids into the ground. The liner shall be plastic sheeting with a minimum thickness of 10 mils with no holes or tears, and anchored beyond the top of the pit with an earthen berm, sand bags, stone, or other structural appurtenance except at the access point. If pre-fabricated washouts are used they must ensure the capture and containment of the concrete wash and be sized based on the expected frequency of concrete pours. They shall be sited as noted in the location criteria. Maintenance All concrete washout facilities shall be inspected daily. Damaged or leaking facilities shall be deactivated and repaired or replaced immediately. Excess rainwater that has accumulated over hardened concrete should be pumped to a stabilized area, such as a grass filter strip. Accumulated hardened material shall be removed when 75% of the storage capacity of the structure is filled. Any excess wash water shall be pumped into a containment vessel and properly disposed of off site. Dispose of the hardened material off-site in a construction/demolition landfill. On-site disposal may be allowed if this has been approved and accepted as part of the projects SWPPP. In that case, the material should be recycled as specified, or buried and covered with a minimum of 2 feet of clean compacted earthfill that is permanently stabilized to prevent erosion. The plastic liner shall be replaced with each cleaning of the washout facility. Inspect the project site frequently to ensure that no concrete discharges are taking place in non-designated areas. STANDARD AND SPECIFICATIONS FOR CONCRETE TRUCK WASHOUT DEPARTMENT OF ENVIRONMENTAL CONSERVA TIONNew York State Deep-Ripping and Decompaction New York State Department of Environmental Conservation Division of Wa ter April 2008 Document Prepared by: John E. Lacey, Land Resource Consultant and Environmental Compliance Monitor (Formerly with the Division of Agricultural Protection and Development Services, NYS Dept. of Agriculture & Markets) 1 Alternative Stormwater Management Deep‐Ripping and Decompaction Description The two-phase practice of 1) “Deep Ripping;” and 2) “Decompaction” (deep subsoiling), of the soil material as a step in the cleanup and restoration/landscaping of a construction site, helps mitigate the physically induced impacts of soil compression; i.e.: soil compaction or the substantial increase in the bulk density of the soil material. Deep Ripping and Decompaction are key factors which help in restoring soil pore space and permeability for water infiltration. Conversely, the physical actions of cut-and-fill work, land grading, the ongoing movement of construction equipment and the transport of building materials throughout a site alter the architecture and structure of the soil, resulting in: the mixing of layers (horizons) of soil materials, compression of those materials and diminished soil porosity which, if left unchecked, severely impairs the soil’s water holding capacity and vertical drainage (rainfall infiltration), from the surface downward. In a humid climate region, compaction damage on a site is virtually guaranteed over the duration of a project. Soil in very moist to wet condition when compacted, will have severely reduced permeability. Figure 1 displays the early stage of the deep-ripping phase (Note that all topsoil was stripped prior to construction access, and it remains stockpiled until the next phase – decompaction – is complete). A heavy-duty tractor is pulling a three-shank ripper on the first of several series of incrementally deepening passes through the construction access corridor's densely compressed subsoil material. Figure 2 illustrates the approximate volumetric composition of a loam surface soil when conditions are good for plant growth, with adequate natural pore space for fluctuating moisture conditions. Fig. 1. A typical deep ripping phase of this practice, during the first in a series of progressively deeper “rips” through severely compressed subsoil. Fig. 2. About 50% of the volume of undisturbed loam surface soil is pore space, when soil is in good condition for plant growth. Brady, 2002. 2 Recommended Application of Practice The objective of Deep Ripping and Decompaction is to effectively fracture (vertically and laterallly) through the thickness of the physically compressed subsoil material (see Figure 3), restoring soil porosity and permeability and aiding infiltration to help reduce runoff. Together with topsoil stripping, the “two-phase” practice of Deep Ripping and Decompaction first became established as a “best management practice” through ongoing success on commercial farmlands affected by heavy utility construction right-of-way projects (transmission pipelines and large power lines). Soil permeability, soil drainage and cropland productivity were restored. For broader construction application, the two-phase practice of Deep Ripping and Decompaction is best adapted to areas impacted with significant soil compaction, on contiguous open portions of large construction sites and inside long, open construction corridors used as temporary access over the duration of construction. Each mitigation area should have minimal above-and-below-ground obstructions for the easy avoidance and maneuvering of a large tractor and ripping/decompacting implements. Conversely, the complete two-phase practice is not recommended in congested or obstructed areas due to the limitations on tractor and implement movement. Benefits Aggressive “deep ripping” through the compressed thickness of exposed subsoil before the replacement/respreading of the topsoil layer, followed by “decompaction,” i.e.: “sub-soiling,” through the restored topsoil layer down into the subsoil, offers the following benefits: • Increases the project (larger size) area’s direct surface infiltration of rainfall by providing the open site’s mitigated soil condition and lowers the demand on concentrated runoff control structures • Enhances direct groundwater recharge through greater dispersion across and through a broader surface than afforded by some runoff-control structural measures • Decreases runoff volume generated and provides hydrologic source control • May be planned for application in feasible open locations either alone or in Fig. 3. Construction site with significant compaction of the deep basal till subsoil extends 24 inches below this exposed cut- and-fill work surface. 3 conjunction with plans for structural practices (e.g., subsurface drain line or infiltration basin) serving the same or contiguous areas • Promotes successful long-term revegetation by restoring soil permeability, drainage and water holding capacity for healthy (rather than restricted) root-system development of trees, shrubs and deep rooted ground cover, minimizing plant drowning during wet periods and burnout during dry periods. Feasibility/Limitations The effectiveness of Deep Ripping and Decompaction is governed mostly by site factors such as: the original (undisturbed) soil’s hydrologic characteristics; the general slope; local weather/timing (soil moisture) for implementation; the space-related freedom of equipment/implement maneuverability (noted above in Recommended Application of Practice), and by the proper selection and operation of tractor and implements (explained below in Design Guidance). The more notable site-related factors include: Soil In the undisturbed condition, each identified soil type comprising a site is grouped into one of four categories of soil hydrology, Hydrologic Soil Group A, B, C or D, determined primarily by a range of characteristics including soil texture, drainage capability when thoroughly wet, and depth to water table. The natural rates of infiltration and transmission of soil-water through the undisturbed soil layers for Group A is “high” with a low runoff potential while soils in Group B are moderate in infiltration and the transmission of soil-water with a moderate runoff potential, depending somewhat on slope. Soils in Group C have slow rates of infiltration and transmission of soil-water and a moderately high runoff potential influenced by soil texture and slope; while soils in Group D have exceptionally slow rates of infiltration and transmission of soil- water, and high runoff potential. In Figure 4, the profile displays the undisturbed horizons of a soil in Hydrologic Soil Group C and the naturally slow rate of infiltration through the subsoil. The slow rate of infiltration begins immediately below the topsoil horizon (30 cm), due to the limited amount of macro pores, e.g.: natural subsoil fractures, worm holes and root channels. Infiltration after the construction-induced mixing and compression of such subsoil material is virtually absent; but can be restored back to this natural level with the two-phase practice of deep ripping and decompaction, followed by the permanent establishment of an appropriate, deep taproot Fig. 4. Profile (in centimeters) displaying the infiltration test result of the natural undisturbed horizons of a soil in Hydrologic Soil Group C. 4 lawn/ground cover to help maintain the restored subsoil structure. Infiltration after construction- induced mixing and compression of such subsoil material can be notably rehabilitated with the Deep Ripping and Decompaction practice, which prepares the site for the appropriate long-term lawn/ground cover mix including deep taproot plants such as clover, fescue or trefoil, etc. needed for all rehabilitated soils. Generally, soils in Hydrologic Soil Groups A and B, which respectively may include deep, well- drained, sandy-gravelly materials or deep, moderately well-drained basal till materials, are among the easier ones to restore permeability and infiltration, by deep ripping and decompaction. Among the many different soils in Hydrologic Soil Group C are those unique glacial tills having a natural fragipan zone, beginning about 12 to 18 inches (30 – 45cm), below surface. Although soils in Hydrologic Soil Group C do require a somewhat more carefully applied level of the Deep Ripping and Decompaction practice, it can greatly benefit such affected areas by reducing the runoff and fostering infiltration to a level equal to that of pre-disturbance. Soils in Hydrologic Soil Group D typically have a permanent high water table close to the surface, influenced by a clay or other highly impervious layer of material. In many locations with clay subsoil material, the bulk density is so naturally high that heavy trafficking has little or no added impact on infiltration; and structural runoff control practices rather than Deep Ripping and Decompaction should be considered. The information about Hydrologic Soil Groups is merely a general guideline. Site-specific data such as limited depths of cut-and-fill grading with minimal removal or translocation of the inherent subsoil materials (as analyzed in the county soil survey) or, conversely, the excavation and translocation of deeper, unconsolidated substratum or consolidated bedrock materials (unlike the analyzed subsoil horizons’ materials referred to in the county soil survey) should always be taken into account. Sites made up with significant quantities of large rocks, or having a very shallow depth to bedrock, are not conducive to deep ripping and decompation (subsoiling); and other measures may be more practical. Slope The two-phase application of 1) deep ripping and 2) decompaction (deep subsoiling), is most practical on flat, gentle and moderate slopes. In some situations, such as but not limited to temporary construction access corridors, inclusion areas that are moderately steep along a project’s otherwise gentle or moderate slope may also be deep ripped and decompacted. For limited instances of moderate steepness on other projects, however, the post-construction land use and the relative alignment of the potential ripping and decompaction work in relation to the lay of the slope should be reviewed for safety and practicality. In broad construction areas predominated by moderately steep or steep slopes, the practice is generally not used. Local Weather/Timing/Soil Moisture Effective fracturing of compressed subsoil material from the exposed work surface, laterally and vertically down through the affected zone is achieved only when the soil material is moderately dry to moderately moist. Neither one of the two-phases, deep ripping nor decompaction (deep 5 Fig. 5. Augered from a depth of 19 inches below the surface of the replaced topsoil, this subsoil sample was hand rolled to a 1/8-inch diameter. The test shows the soil at this site stretches out too far without crumbling; it indicates the material is in a plastic state of consistence, too wet for final decompaction (deep subsoiling) at this time. subsoiling), can be effectively conducted when the soil material (subsoil or replaced topsoil) is in either a “plastic” or “liquid” state of soil consistency. Pulling the respective implements legs through the soil when it is overly moist only results in the “slicing and smearing” of the material or added “squeezing and compression” instead of the necessary fracturing. Ample drying time is needed for a “rippable” soil condition not merely in the material close to the surface, but throughout the material located down to the bottom of the physically compressed zone of the subsoil. The “poor man’s Atterberg field test” for soil plasticity is a simple “hand-roll” method used for quick, on-site determination of whether or not the moisture level of the affected soil material is low enough for: effective deep ripping of subsoil; respreading of topsoil in a friable state; and final decompaction (deep subsoiling). Using a sample of soil material obtained from the planned bottom depth of ripping, e.g.: 20 - 24 inches below exposed subsoil surface, the sample is hand rolled between the palms down to a 1/8-inch diameter thread. (Use the same test for stored topsoil material before respreading on the site.) If the respective soil sample crumbles apart in segments no greater than 3/8 of an inch long, by the time it is rolled down to 1/8 inch diameter, it is low enough in moisture for deep ripping (or topsoil replacement), and decompaction. Conversely, as shown in Figure 5, if the rolled sample stretches out in increments greater than 3/8 of an inch long before crumbling, it is in a “plastic” state of soil consistency and is too wet for subsoil ripping (as well as topsoil replacement) and final decompaction. Design Guidance Beyond the above-noted site factors, a vital requirement for the effective Deep Ripping and Decompaction (deep subsoiling), is implementing the practice in its distinct, two-phase process: 1) Deep rip the affected thickness of exposed subsoil material (see Figure 10 and 11), aggressively fracturing it before the protected topsoil is reapplied on the site (see Figure 12); and 2) Decompact (deep subsoil), simultaneously through the restored topsoil layer and the upper half of the affected subsoil (Figure 13). The second phase, “decompaction,” mitigates the partial recompaction which occurs during the heavy process of topsoil spreading/grading. Prior to deep ripping and decompacting the site, all construction activity, including construction equipment and material storage, site cleanup and trafficking (Figure 14), should be finished; and the site closed off to further disturbance. Likewise, once the practice is underway and the area’s soil permeability and 6 Fig. 6. A light duty chisel implement, not adequate for either the deep ripping or decompaction (deep subsoiling) phase. rainfall infiltration are being restored, a policy limiting all further traffic to permanent travel lanes is maintained. The other critical elements, outlined below, are: using the proper implements (deep, heavy-duty rippers and subsoilers), and ample pulling-power equipment (tractors); and conducting the practice at the appropriate speed, depth and pattern(s) of movement. Note that an appropriate plan for the separate practice of establishing a healthy perennial ground cover, with deep rooting to help maintain the restored soil structure, should be developed in advance. This may require the assistance of an agronomist or landscape horticulturist. Implements Avoid the use of all undersize implements. The small-to-medium, light-duty tool will, at best, only “scarify” the uppermost surface portion of the mass of compacted subsoil material. The term “chisel plow” is commonly but incorrectly applied to a broad range of implements. While a few may be adapted for the moderate subsoiling of non-impacted soils, the majority are less durable and used for only lighter land-fitting (see Figure 6). Use a “heavy duty” agricultural-grade, deep ripper (see Figures 7,9,10 and 11) for the first phase: the lateral and vertical fracturing of the mass of exposed and compressed subsoil, down and through, to the bottom of impact, prior to the replacement of the topsoil layer. (Any oversize rocks which are uplifted to the subsoil surface during the deep ripping phase are picked and removed.) Like the heavy-duty class of implement for the first phase, the decompaction (deep subsoiling) of Phase 2 is conducted with the heavy-duty version of the deep subsoiler. More preferable is the angled-leg variety of deep subsoiler (shown in Figures 8 and 13). It minimizes the inversion of the subsoil and topsoil layers while laterally and vertically fracturing the upper half of the previously ripped subsoil layer and all of the topsoil layer by delivering a momentary, wave-like “lifting and shattering” action up through the soil layers as it is pulled. Fig. 7. One of several variations of an agricultural ripper. This unit has long, rugged shanks mounted on a steel V-frame for deep, aggressive fracturing through Phase 1. 7 Fig. 8. A deep, angled-leg subsoiler, ideal for Phase 2 decompaction of after the topsoil layer is graded on top of the ripped subsoil. Pulling-Power of Equipment Use the following rule of thumb for tractor horsepower (hp) whenever deep ripping and decompacting a significantly impacted site: For both types of implement, have at least 40 hp of tractor pull available for each mounted shank/ leg. Using the examples of a 3-shank and a 5-shank implement, the respective tractors should have 120 and 200 hp available for fracturing down to the final depth of 20-to-24 inches per phase. Final depth for the deep ripping in Phase 1 is achieved incrementally by a progressive series of passes (see Depth and Patterns of Movement, below); while for Phase 2, the full operating depth of the deep subsoiler is applied from the beginning. The operating speed for pulling both types of implement should not exceed 2 to 3 mph. At this slow and managed rate of operating speed, maximum functional performance is sustained by the tractor and the implement performing the soil fracturing. Referring to Figure 8, the implement is the 6-leg version of the deep angled-leg subsoiler. Its two outside legs are “chained up” so that only four legs will be engaged (at the maximum depth), requiring no less than 160 hp, (rather than 240 hp) of pull. The 4-wheel drive, articulated-frame tractor in Figure 8 is 174 hp. It will be decompacting this unobstructed, former construction access area simultaneously through 11 inches of replaced topsoil and the upper 12 inches of the previously deep-ripped subsoil. In constricted areas of Phase 1) Deep Ripping, a medium-size tractor with adequate hp, such as the one in Figure 9 pulling a 3-shank deep ripper, may be more maneuverable. Some industrial-grade variations of ripping implements are attached to power graders and bulldozers. Although highly durable, they are generally not recommended. Typically, the shanks or “teeth” of these rippers are too short and stout; and they are mounted too far apart to achieve the well-distributed type of lateral and vertical fracturing of the soil materials necessary to restore soil permeability and infiltration. In addition, the power graders and bulldozers, as pullers, are far less maneuverable for turns and patterns than the tractor. Fig. 9. This medium tractor is pulling a 3- shank deep ripper. The severely compacted construction access corridor is narrow, and the 120 hp tractor is more maneuverable for Phase 1 deep ripping (subsoil fracturing), here. 8 Depth and Patterns of Movement As previously noted both Phase 1 Deep Ripping through significantly compressed, exposed subsoil and Phase 2 Decompaction (deep subsoiling) through the replaced topsoil and upper subsoil need to be performed at maximum capable depth of each implement. With an implement’s guide wheels attached, some have a “normal” maximum operating depth of 18 inches, while others may go deeper. In many situations, however, the tractor/implement operator must first remove the guide wheels and other non essential elements from the implement. This adapts the ripper or the deep subsoiler for skillful pulling with its frame only a few inches above surface, while the shanks or legs, fracture the soil material 20-to-24 inches deep. There may be construction sites where the depth of the exposed subsoil’s compression is moderate, e.g.: 12 inches, rather than deep. This can be verified by using a ¾ inch cone penetrometer and a shovel to test the subsoil for its level of compaction, incrementally, every three inches of increasing depth. Once the full thickness of the subsoil’s compacted zone is finally “pieced” and there is a significant drop in the psi measurements of the soil penetrometer, the depth/thickness of compaction is determined. This is repeated at several representative locations of the construction site. If the thickness of the site’s subsoil compaction is verified as, for example, ten inches, then the Phase 1 Deep Ripping can be correspondingly reduced to the implement’s minimum operable depth of 12 inches. However, the Phase 2 simultaneous Decompation (subsoiling) of an 11 inch thick layer of replaced topsoil and the upper subsoil should run at the subsoiling implements full operating depth. Typically, three separate series (patterns) are used for both the Phase 1 Deep Ripping and the Phase 2 Decompaction on significantly compacted sites. For Phase 1, each series begins with a moderate depth of rip and, by repeat-pass, continues until full depth is reached. Phase 2 applies the full depth of Decompation (subsoiling), from the beginning. Every separate series (pattern) consists of parallel, forward-and-return runs, with each progressive Fig. 11. A repeat run of the 3-shank ripper along the same patterned pass area as Fig. 9; here, incrementally reaching 18 of the needed 22 inches of subsoil fracture. Fig. 10. An early pass with a 3-shank deep ripper penetrating only 8 inches into this worksite’s severely compressed subsoil. 9 pass of the implement’s legs or shanks evenly staggered between those from the previous pass. This compensates for the shank or leg-spacing on the implement, e.g., with 24-to-30 inches between each shank or leg. The staggered return pass ensures lateral and vertical fracturing actuated every 12 to 15 inches across the densely compressed soil mass. Large, Unobstructed Areas For larger easy areas, use the standard patterns of movement: ● The first series (pattern) of passes is applied lengthwise, parallel with the longest spread of the site; gradually progressing across the site’s width, with each successive pass. ● The second series runs obliquely, crossing the first series at an angle of about 45 degrees. ● The third series runs at right angle (or 90 degrees), to the first series to complete the fracturing and shattering on severely compacted sites, and avoid leaving large unbroken blocks of compressed soil material. (In certain instances, the third series may be optional, depending on how thoroughly the first two series loosen the material and eliminate large chunks/blocks of material as verified by tests with a ¾- inch cone penetrometer.) Corridors In long corridors of limited width and less maneuverability than larger sites, e.g.: along compacted areas used as temporary construction access, a modified series of pattern passes are used. ● First, apply the same initial lengthwise, parallel series of passes described above. Fig. 12. Moderately dry topsoil is being replaced on the affected site now that Phase 1 deep ripping of the compressed subsoil is complete. Fig. 13. The same deep, angled-leg subsoiler shown in Fig. 7 is engaged at maximum depth for Phase 2, decompaction (deep soiling), of the replaced topsoil and the upper subsoil materials. 10 Fig. 15. The same site as Fig. 14 after deep ripping of the exposed subsoil, topsoil replacement, decompaction through the topsoil and upper subsoil and final surface tillage and revegetation to maintain soil permeability and infiltration. ● A second series of passes makes a broad “S” shaped pattern of rips, continually and gradually alternating the “S” curves between opposite edges inside the compacted corridor. ● The third and final series again uses the broad, alternating S pattern, but it is “flip-flopped” to continually cross the previous S pattern along the corridor’s centerline. This final series of the S pattern curves back along the edge areas skipped by the second series. Maintenance and Cost Once the two-phase practice of Deep Ripping and Decompation is completed, two items are essential for maintaining a site’s soil porosity and permeability for infiltration. They are: planting and maintaining the appropriate ground cover with deep roots to maintain the soil structure (see Figure 15); and keeping the site free of traffic or other weight loads. Note that site-specific choice of an appropriate vegetative ground-cover seed mix, including the proper seeding ratio of one or more perennial species with a deep taproot system and the proper amount of lime and soil nutrients (fertilizer mix) adapted to the soil-needs, are basic to the final practice of landscaping, i.e: surface tillage, seeding/planting/fertilizing and culti-packing or mulching is applied. The "maintenance" of an effectively deep-ripped and decompacted area is generally limited to the successful perennial (long-term) landscape ground cover; as long as no weight-bearing force of soil compaction is applied. Fig. 14. The severely compacted soil of a temporary construction yard used daily by heavy equipment for four months; shown before deep ripping, topsoil replacement, and decompaction. 11 The Deep Ripping and Decompaction practice is, by necessity, more extensive than periodic subsoiling of farmland.The cost of deep ripping and decompacting (deep subsoiling), will vary according to the depth and severity of soil-material compression and the relative amount of tractor and implement time that is required. In some instances, depending on open maneuverability, two-to-three acres of compacted project area may be deep-ripped in one day. In other situations of more severe compaction and - or less maneuverability, as little as one acre may be fully ripped in a day. Generally, if the Phase 1) Deep Ripping is fully effective, the Phase 2) Decompaction should be completed in 2/3 to 3/4 of the time required for Phase 1. Using the example of two acres of Phase 1) Deep Ripping in one day, at $1800 per day, the net cost is $900 per acre. If the Phase 2) Decompacting or deep subsoiling takes 3/4 the time as Phase 1, it costs $675 per acre for a combined total of $1575 per acre to complete the practice (these figures do not include the cost of the separate practice of topsoil stripping and replacement). Due to the many variables, it must be recognized that cost will be determined by the specific conditions or constraints of the site and the availability of proper equipment. 12 Resources Publications: ● American Society of Agricultural Engineers. 1971.

Conditions Where Practice Applies On construction roads, access points, and other disturbed areas subject to surface dust movement and dust blowing where off-site damage may occur if dust is not controlled. Design Criteria Construction operations should be scheduled to minimize the amount of area disturbed at one time. Buffer areas of vegetation should be left where practical. Temporary or permanent stabilization measures shall be installed. No specific design criteria is given; see construction specifications below for common methods of dust control. Water quality must be considered when materials are selected for dust control. Where there is a potential for the material to wash off to a stream, ingredient information must be provided to the NYSDEC. No polymer application shall take place without written approval from the NYSDEC. Construction Specifications A. Non-driving Areas – These areas use products and materials applied or placed on soil surfaces to prevent airborne migration of soil particles. Vegetative Cover – For disturbed areas not subject to traffic, vegetation provides the most practical method of dust control (see Section 3). Mulch (including gravel mulch) – Mulch offers a fast effective means of controlling dust. This can also include rolled erosion control blankets. Spray adhesives – These are products generally composed of polymers in a liquid or solid form that are mixed with water to form an emulsion that is sprayed on the soil surface with typical hydroseeding equipment. The mixing ratios and application rates will be in accordance with the manufacturer’s recommendations for the specific soils on the site. In no case should the application of these adhesives be made on wet soils or if there is a probability of precipitation within 48 hours of its proposed use. Material Safety Data Sheets will be provided to all applicators and others working with the material. B. Driving Areas – These areas utilize water, polymer emulsions, and barriers to prevent dust movement from the traffic surface into the air. Sprinkling – The site may be sprayed with water until the surface is wet. This is especially effective on haul roads and access route to provide short term limited dust control. Polymer Additives – These polymers are mixed with water and applied to the driving surface by a water truck with a gravity feed drip bar, spray bar or automated distributor truck. The mixing ratios and application rates will be in accordance with the manufacturer’s recommendations. Incorporation of the emulsion into the soil will be done to the appropriate depth based on expected traffic. Compaction after incorporation will be by vibratory roller to a minimum of 95%. The prepared surface shall be moist and no application of the polymer will be made if there is a probability of precipitation within 48 hours of its proposed use. Material Safety Data Sheets will be provided to all applicators working with the material. Barriers – Woven geo-textiles can be placed on the driving surface to effectively reduce dust throw and particle migration on haul roads. Stone can also be used for construction roads for effective dust control. Windbreak – A silt fence or similar barrier can control air currents at intervals equal to ten times the barrier height. Preserve existing wind barrier vegetation as much as practical. Maintenance Maintain dust control measures through dry weather periods until all disturbed areas are stabilized. STANDARD AND SPECIFICATIONS FOR DUST CONTROL July 2016 Page 2.26 New York State Standards and Specifications For Erosion and Sediment Control Definition & Scope The protection of trees, shrubs, ground cover and other vegetation from damage by construction equipment. In order to preserve existing vegetation determined to be important for soil erosion control, water quality protection, shade, screening, buffers, wildlife habitat, wetland protection, and other values. Conditions Where Practices Applies On planned construction sites where valued vegetation exists and needs to be preserved. Design Criteria 1. Planning Considerations A. Inventory: 1) Property boundaries, topography, vegetation and soils information should be gathered. Identify potentially high erosion areas, areas with tree windthrow potential, etc. A vegetative cover type map should be made on a copy of a topographic map which shows other natural and manmade features. Vegetation that is desirable to preserve because of its value for screening, shade, critical erosion control, endangered species, aesthetics, etc., should be identified and marked on the map. 2) Based upon this data, general statements should be prepared about the present condition, potential problem areas, and unique features of the property. B. Planning: 1) After engineering plans (plot maps) are prepared, another field review should take place and recommendations made for the vegetation to be saved. Minor adjustments in location of roads, dwellings, and utilities may be needed. Construction on steep slopes, erodible soils, wetlands, and streams should be avoided. Clearing limits should be delineated (See “Determine Limits of Clearing and Grading” on page 2.2). 2) Areas to be seeded and planted should be identified. Remaining vegetation should blend with their surroundings and/or provide special function such as a filter strip, buffer zone, or screen. 3) Trees and shrubs of special seasonal interest, such as flowering dogwood, red maple, striped maple, serviceberry, or shadbush, and valuable potential shade trees should be identified and marked for special protective treatment as appropriate. 4) Trees to be cut should be marked on the plans. If timber can be removed for salable products, a forester should be consulted for marketing advice. 5) Trees that may become a hazard to people, personal property, or utilities should be removed. These include trees that are weak-wooded, disease-prone, subject to windthrow, or those that have severely damaged root systems. 6) The vigor of remaining trees may be improved by a selective thinning. A forester should be consulted for implementing this practice. 2. Measures to Protect Vegetation A. Limit soil placement over existing tree and shrub roots to a maximum of 3 inches. Soils with loamy texture and good structure should be used. B. Use retaining walls and terraces to protect roots of trees and shrubs when grades are lowered. Lowered grades should start no closer than the dripline of the tree. For narrow-canopied trees and shrubs, the stem diameter in inches is converted to feet and doubled, such that a 10 inch tree should be protected to 20 feet. C. Trenching across tree root systems should be the same minimum distance from the trunk, as in “B”. Tunnels under root systems for underground utilities should start 18 inches or deeper below the normal ground surface. Tree roots which must be severed should be cut clean. Backfill material that will be in contact with the roots should be topsoil or a prepared planting soil mixture. D. Construct sturdy fences, or barriers, of wood, steel, or other protective material around valuable STANDARD AND SPECIFICATIONS FOR PROTECTING VEGETATION DURING CONSTRUCTION New York State Standards and Specifications Page 2.27 July 2016 For Erosion and Sediment Control vegetation for protection from construction equipment. Place barriers far enough away from trees, but not less than the specifications in "B", so that tall equipment such as backhoes and dump trucks do not contact tree branches. E. Construction limits should be identified and clearly marked to exclude equipment. F. Avoid spills of oil/gas and other contaminants. G. Obstructive and broken branches should be pruned properly. The branch collar on all branches whether living or dead should not be damaged. The 3 or 4 cut method should be used on all branches larger than two inches at the cut. First cut about one-third the way through the underside of the limb (about 6-12 inches from the tree trunk). Then (approximately an inch further out) make a second cut through the limb from the upper side. When the branch is removed, there is no splintering of the main tree trunk. Remove the stub. If the branch is larger than 5-6 inches in diameter, use the four cut system. Cuts 1 and 2 remain the same and cut 3 should be from the underside of the limb, on the outside of the branch collar. Cut 4 should be from the top and in alignment with the 3rd cut. Cut 3 should be 1/4 to 1/3 the way through the limb. This will prevent the bark from peeling down the trunk. Do not paint the cut surface. H. Penalties for damage to valuable trees, shrubs, and herbaceous plants should be clearly spelled out in the contract. PROTECTING TREES IN HEAVY USE AREAS The compaction of soil over the roots of trees and shrubs by the trampling of recreationists, vehicular traffic, etc., reduces oxygen, water, and nutrient uptake by feeder roots. This weakens and may eventually kill the plants. Table 2.6 rates the “Susceptibility of Tree Species to Compaction.” Where heavy compaction is anticipated, apply and maintain a 3 to 4 inch layer of undecayed wood chips or 2 inches of No. 2 washed, crushed gravel. In addition, use of a wooden or plastic mat may be used to lessen compaction, if applicable.

November 2016 Page 5.54 New York State Standards and Specifica- tions For Erosion and Sediment Control STANDARD AND SPECIFICATIONS FOR SILT FENCE Definition & Scope A temporary barrier of geotextile fabric installed on the contours across a slope used to intercept sediment laden runoff from small drainage areas of disturbed soil by tem- porarily ponding the sediment laden runoff allowing settling to occur. The maximum period of use is limited by the ul- traviolet stability of the fabric (approximately one year). Conditions Where Practice Applies A silt fence may be used subject to the following condi- tions: 1. Maximum allowable slope length and fence length will not exceed the limits shown in the Design Criteria for the specific type of silt fence used ; and 2. Maximum ponding depth of 1.5 feet behind the fence; and 3. Erosion would occur in the form of sheet erosion; and 4. There is no concentration of water flowing to the barri- er; and 5. Soil conditions allow for proper keying of fabric, or other anchorage, to prevent blowouts. Design Criteria 1. Design computations are not required for installations of 1 month or less. Longer installation periods should be designed for expected runoff. 2. All silt fences shall be placed as close to the disturbed area as possible, but at least 10 feet from the toe of a slope steeper than 3H:1V, to allow for maintenance and roll down. The area beyond the fence must be undis- turbed or stabilized. 3. The type of silt fence specified for each location on the plan shall not exceed the maximum slope length and maximum fence length requirements shown in the fol- lowing table: 4. Silt fence shall be removed as soon as the disturbed area has achieved final stabilization. The silt fence shall be installed in accordance with the ap- propriate details. Where ends of filter cloth come together, they shall be overlapped, folded and stapled to prevent sedi- ment bypass. Butt joints are not acceptable. A detail of the silt fence shall be shown on the plan. See Figure 5.30 on page 5.56 for Reinforced Silt Fence as an example of details to be provided. Criteria for Silt Fence Materials 1.

Reinforced Silt Fence (RSF) is fabric placed against welded wire fabric with anchored steel posts driven 16 inches in the ground. Super Silt Fence (SSF) is fabric placed against chain link fence as support backing with posts driven 3 feet in the ground. November 2016 Page 4.52 New York State Standards and Specifications For Erosion and Sediment Control Definition & Scope The decompaction of areas of a development site or construction project where soils have been disturbed to recover the original properties and porosity of the soil; thus providing a sustainable growth medium for vegetation, reduction of runoff and filtering of pollutants from stormwater runoff. Conditions Where Practice Applies Soil restoration is to be applied to areas whose heavy construction traffic is done and final stabilization is to begin. This is generally applied in the cleanup, site restoration, and landscaping phase of construction followed by the permanent establishment of an appropriate ground cover to maintain the soil structure. Soil restoration measures should be applied over and adjacent to any runoff reduction practices to achieve design performance. 2. Soil restoration will be completed in accordance with Table 4.6 on page 4.53. Specification for Full Soil Restoration During periods of relatively low to moderate subsoil moisture, the disturbed subsoils are returned to rough grade and the following Soil Restoration steps applied: 1. Apply 3 inches of compost over subsoil. The compost shall be well decomposed (matured at least 3 months), weed-free, organic matter. It shall be aerobically composted, possess no objectionable odors, and contain less than 1%, by dry weight, of man-made foreign matter. The physical parameters of the compost shall meet the standards listed in Table 5.2 - Compost Standards Table, except for “Particle Size” 100% will pass the 1/2” sieve. Note: All biosolids compost produced in New York State (or approved for importation) must meet NYS DEC’s 6 NYCRR Part 360 (Solid Waste Management Facilities) requirements. The Part 360 requirements are equal to or more stringent than 40 CFR Part 503 which ensure safe standards for pathogen reduction and heavy metals content. STANDARD AND SPECIFICATIONS FOR SOIL RESTORATION Design Criteria 1. Soil restoration areas will be designated on the plan views of areas to be disturbed. 2. Till compost into subsoil to a depth of at least 12 inches using a cat-mounted ripper, tractor mounted disc, or tiller, to mix and circulate air and compost into the subsoil. 3. Rock-pick until uplifted stone/rock materials of four inches and larger size are cleaned off the site. 4. Apply topsoil to a depth of 6 inches. 5. Vegetate as required by the seeding plan. Use appropriate ground cover with deep roots to maintain the soil structure. 6. Topsoil may be manufactured as a mixture or a mineral component and organic material such as compost.

Table 4.6 Soil Restoration Requirements At the end of the project an inspector should be able to push a 3/8” metal bar 12 inches into the soil just with body weight. This should not be performed within the drip line of any existing trees or over utility installations that are within 24 inches of the surface. Maintenance Keep the site free of vehicular and foot traffic or other weight loads. Consider pedestrian footpaths. November 2016 Page 2.30 New York State Standards and Specifications For Erosion and Sediment Control Definition & Scope A stabilized pad of aggregate underlain with geotextile 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 stabilized construction access is to reduce or eliminate the tracking of sediment onto public rights-of-way or streets. Conditions Where Practice Applies A stabilized construction access shall be used at all points of construction ingress and egress. Design Criteria See Figure 2.1 on page 2.31 for details. Aggregate Size: Use a matrix of 1-4 inch stone, or reclaimed or recycled concrete equivalent. Thickness: Not less than six (6) inches. Width: 12-foot minimum but not less than the full width of points where ingress or egress occurs. 24-foot minimum if there is only one access to the site. Length: As required, but not less than 50 feet (except on a single residence lot where a 30 foot minimum would apply). Geotextile: To be placed over the entire area to be covered with aggregate. Filter cloth will not be required on a single- family residence lot. Piping of surface water under entrance shall be provided as required. If piping is impossible, a mountable berm with 5:1 slopes will be permitted. Criteria for Geotextile: The geotextile shall be woven or nonwoven fabric consisting only of continuous chain polymeric filaments or yarns of polyester. The fabric shall be inert to commonly encountered chemicals, hydro-carbons, mildew, rot resistant, and conform to the fabric properties as shown: Maintenance The access shall be maintained in a condition which will prevent tracking of sediment onto public rights-of-way or streets. This may require periodic top dressing with additional aggregate. All sediment spilled, dropped, or washed onto public rights-of-way must be removed immediately. When necessary, wheels must be cleaned to remove sediment prior to entrance onto public rights-of-way. When washing is required, it shall be done on an area stabilized with aggregate, which drains into an approved sediment- trapping device. All sediment shall be prevented from entering storm drains, ditches, or watercourses.

New York State Standards and Specifications Page 3.53 November 2016 For Erosion and Sediment Control Figure 3.22 Water Bar Detail November 2016 Page 2.38 New York State Standards and Specifications For Erosion and Sediment Control Definition & Scope A temporary site specific, enhanced erosion and sediment control plan to manage runoff and sediment at the site during construction activities in the winter months to protect off-site water resources. Conditions Where Practice Applies This standard applies to all construction activities involved with ongoing land disturbance and exposure between November 15th to the following April 1st. Design Criteria 1. Prepare a snow management plan with adequate storage for snow and control of melt water, requiring cleared snow to be stored in a manner not affecting ongoing construction activities. 2. Enlarge and stabilize access points to provide for snow management and stockpiling. Snow management activities must not destroy or degrade installed erosion and sediment control practices. 3. A minimum 25 foot buffer shall be maintained from all perimeter controls such as silt fence. Mark silt fence with tall stakes that are visible above the snow pack. 4. Edges of disturbed areas that drain to a waterbody within 100 feet will have 2 rows of silt fence, 5 feet apart, installed on the contour. 5. Drainage structures must be kept open and free of snow and ice dams. All debris, ice dams, or debris from plowing operations, that restrict the flow of runoff and meltwater, shall be removed. 6. Sediment barriers must be installed at all appropriate perimeter and sensitive locations. Silt fence and other practices requiring earth disturbance must be installed before the ground freezes. 7. Soil stockpiles must be protected by the use of established vegetation, anchored straw mulch, rolled stabilization matting, or other durable covering. A barrier must be installed at least 15 feet from the toe of the stockpile to prevent soil migration and to capture loose soil. 8. In areas where soil disturbance activity has temporarily or permanently ceased, the application of soil stabilization measures should be initiated by the end of the next business day and completed within three (3) days. Rolled erosion control blankets must be used on all slopes 3 horizontal to 1 vertical or steeper. 9. If straw mulch alone is used for temporary stabilization, it shall be applied at double the standard rate of 2 tons per acre, making the application rate 4 tons per acre. Other manufactured mulches should be applied at double the manufacturer’s recommended rate. 10. To ensure adequate stabilization of disturbed soil in advance of a melt event, areas of disturbed soil should be stabilized at the end of each work day unless: a. work will resume within 24 hours in the same area and no precipitation is forecast or; b. the work is in disturbed areas that collect and retain runoff, such as open utility trenches, foundation excavations, or water management areas. 11. Use stone paths to stabilize access perimeters of buildings under construction and areas where construction vehicle traffic is anticipated. Stone paths should be a minimum 10 feet in width but wider as necessary to accommodate equipment. Maintenance The site shall be inspected frequently to ensure that the erosion and sediment control plan is performing its winter stabilization function. If the site will not have earth disturbing activities ongoing during the “winter season”, all bare exposed soil must be stabilized by established vegetation, straw or other acceptable mulch, matting, rock, or other approved material such as rolled erosion control products. Seeding of areas with mulch cover is preferred but seeding alone is not acceptable for proper stabilization. Compliance inspections must be performed and reports filed properly in accordance with the SWPPP for all sites under a winter shutdown.

Preamble to Site Assessment and Inspections The Following Information To Be Read By All Person’s Involved in The Construction of Stormwater Re- lated Activities: The Operator agrees to have a qualified inspector1 conduct an assessment of the site prior to the commence- ment of construction2 and certify in this inspection report that the appropriate erosion and sediment controls described in the SWPPP have been adequately installed or implemented to ensure overall preparedness of the site for the commencement of construction. Prior to the commencement of construction, the Operator shall certify in this site logbook that the SWPPP has been prepared in accordance with the State’s standards and meets all Federal, State and local erosion and sediment control requirements. A preconstruction meeting should be held to review all of the SWPPP requirements with construction personnel. When construction starts, site inspections shall be conducted by the qualified inspector at least every 7 cal- endar days. The Operator shall maintain a record of all inspection reports in this site logbook. The site log- book shall be maintained on site and be made available to the permitting authorities upon request. Prior to filing the Notice of Termination or the end of permit term, the Operator shall have a qualified in- spector perform a final site inspection. The qualified inspector shall certify that the site has undergone final stabilization3 using either vegetative or structural stabilization methods and that all temporary erosion and sediment controls (such as silt fencing) not needed for long-term erosion control have been removed. In addition, the Operator must identify and certify that all permanent structures described in the SWPPP have been constructed and provide the owner(s) with an operation and maintenance plan that ensures the struc- ture(s) continuously functions as designed. 1 Refer to “Qualified Inspector” inspection requirements in the current SPDES General Permit for Stormwater Discharges from Construction Activity for complete list of inspection requirements. 2 “Commencement of construction” means the initial removal of vegetation and disturbance of soils associated with clearing, grading or excavating activities or other construction activities. 3 “Final stabilization” means that all soil-disturbing activities at the site have been completed and a uniform, perennial vegetative cover with a density of eighty (80) percent has been established or equivalent stabilization measures (such as the use of mulches or geotextiles) have been employed on all unpaved areas and areas not covered by permanent struc- tures.

This has resulted in an increase in the number of questions on Construction General Permit (CGP) and Stormwater Pollution Prevention Plan (SWPPP) requirements from design professionals because the current CGP (GP- 0-15-002) does not include a specific reference to the SWPPP requirements for solar panel projects in Tables 1 and 2 of Appendix B. To address this issue, the Division of Water (DOW) has developed the following guidance on CGP/SWPPP requirements for the different types of solar panel projects. Scenario 1 The DOW considers solar panel projects designed and constructed in accordance with the following criteria to be a “Land clearing and grading for the purposes of creating vegetated open space (i.e. recreational parks, lawns, meadows, fields)” type project as listed in Table 1, Appendix B of the CGP. Therefore, the SWPPP for this type of project will typically just need to address erosion and sediment controls. 1. Solar panels are constructed on post or rack systems and elevated off the ground surface, 2. The panels are spaced apart so that rain water can flow off the down gradient side of the panel and continue as sheet flow across the ground surface*, 3. For solar panels constructed on slopes, the individual rows of solar panels are generally installed along the contour so rain water sheet flows down slope*, 4. The ground surface below the panels consist of a well-established vegetative cover (see “Final Stabilization” definition in Appendix A of the CGP), 5. The project does not include the construction of any traditional impervious areas (i.e. buildings, substation pads, gravel access roads or parking areas, etc.), 6. Construction of the solar panels will not alter the hydrology from pre -to post development conditions (see Appendix A of the CGP, for definition of “Alter the hydrology…”). Note: The design professional shall perform the necessary site assessment/hydrology analysis to make this determination. *Refer to Maryland’s “Stormwater Design Guidance- Solar Panel Installations” attached for guidance on panel installation. **See notes below for additional criteria. Scenario 2 If the design and construction of the solar panels meets all the criteria above, except for item 6, the project will fall under the “All other construction activities that include the construction or reconstruction of impervious area or alter the hydrology from pre-to post development conditions, and are not listed in Table 1” project type as listed in Table 2, Appendix B of the CGP. Therefore, the SWPPP for this type of project must address post-construction stormwater practices designed in accordance with the sizing criteria in Chapter 4 of the NYS Stormwater Management Design Manual, dated January 2015 (Note: Chapter 10 for projects in NYC EOH Watershed). The Water Quality Volume (WQv)/Runoff Reduction Volume (RRv) sizing criteria can be addressed by designing and constructing the solar panels in accordance with the criteria in items 1 – 4 above, however, the quantity control sizing criteria (Cpv, Qp and Qf) from Chapter 4 (or 10) of the Design Manual must still be addressed, unless one of the waiver criteria from Chapter 4 can be applied. **See notes below for additional criteria. ** Notes - Item 1: For solar panel projects where the panels are mounted directly to the ground (i.e. no space below panel to allow for infiltration of runoff), the SWPPP must address post-construction stormwater management controls designed in accordance with the sizing criteria in Chapter 4 of the NYS Stormwater Management Design Manual, dated January 2015 (Note: Chapter 10 for projects in NYC EOH Watershed). - Item 5: For solar panel projects that include the construction of traditional impervious areas (i.e. buildings, substation pads, gravel access roads or parking areas, etc.), the SWPPP must address post-construction stormwater management controls for those areas of the project. This applies to both Scenario 1 and 2 above. cc: Carol Lamb-Lafay, BWP Dave Gasper, BWP PROJECT TITLE LOCATION WO. NO. CVE Solar- Quaker Queensbury, New York YES NO Comments Scenario 2 The area of the array does not need to be included in the calculations to determine the stormwater management sizing. The proposed impervious area (i.e. equipment pads) will need post-construction stormwater management. Scenario 1 X X Criterion Met 6. Construction of the solar panels will not alter the hydrology from pre-to post development conditions (see Appendix A of the CGP, for definition of “Alter the hydrology…”). Note: The design professional shall perform the necessary site assessment/hydrology analysis to make this determination. 3. For solar panels constructed on slopes, the individual rows of solar panels are generally installed along the contour so rain water sheet flows down slope*, 4. The ground surface below the panels consist of a well-established vegetative cover (see “Final Stabilization” definition in Appendix A of the CGP), 5. The project does not include the construction of any traditional impervious areas (i.e. buildings, substation pads, gravel access roads or parking areas, etc.), X X Conclusions: NYSDEC SOLAR PANEL GUIDANCE INVENTORY DATE 5/20/2021 1. Solar panels are constructed on post or rack systems and elevated off the ground surface, 2. The panels are spaced apart so that rain water can flow off the down gradient side of the panel and continue as sheet flow across the ground surface, (Refer to Maryland’s “Stormwater Design Guidance- Solar Panel Installations”) The DOW considers solar panel projects designed and constructed in accordance with the following criteria to be a “Land clearing and grading for the purposes of creating vegetated open space (i.e. recreational parks, lawns, meadows, fields)” type project as listed in Table 1, Appendix B of the CGP.

Submitted To:Submitted By: 1.0 INTRODUCTION Tectonic Engineering Consultants, Geologists & Land Surveyors D.P.C. (“Tectonic”) was retained by the CVE Group to perform a habitat assessment and complete a rare, threatened, and endangered (RTE) species report for two (2) parcels of land that are located on Queensbury Avenue, Town of Queensbury, Warren County, New York; which are designated as Tax IDs: 303.11-1-4.1 and 303.15-1-25.2 (the “Survey Area”). A street map and aerial map of the Survey Area are included in Appendix I. The RTE species report aids in the identification and subsequent documentation of potential adverse impacts to flora, fauna, and overall habitat characteristics in the Survey Area. The results of this study will supply general baseline data on the ecological characteristics and observed communities in the Survey Area in accordance with the following: • Endangered Species Act of 1973 (ESA) • Bald and Golden Eagle Protection Act (BGEPA) • Migratory Bird Act (MBA) • Magnuson-Stevens Act (MSA) • Environmental Conservation Law Article 11 and 6 NYCRR Part 182 This formal habitat assessment and RTE species report was performed in order to determine what, if any, state and/or federally listed threatened and endangered species and/or other protected species or associated suitable and/or critical habitat may occur or potentially be impacted by construction activity in the Survey Area. 2.0 SITE CHARACTERIZATION 2.1 PRELIMINARY SITE DESCRIPTION The Survey Area is located in a lowland area within the Central Hudson ecozone. Topography within the Survey Area ranges from approximately 320 feet Above Mean Sea Level (AMSL) to 390 feet AMSL. The Survey Area is primarily forested. A topographic map is included in Appendix II. The majority of the Survey Area is characterized by undeveloped forested uplands and wetlands, successional fields, and successional shrublands. Adjacent land west of the Survey Area is primarily comprised of forested land; adjacent land north of the Survey Area is comprised of forested land and land associated with an airport; adjacent land east of the Survey Area is comprised of fields on land associated with an ariport; and adjacent land south of the Survey Area is predominantly comprised of commercial properties and forested land. page 2 of 7 2.2 SOILS According to the Natural Resource Conservation Services (NRCS) online websoil survey, assessed January 18, 2021, a total of four (4) soil types occur within the Survey Area (Appendix III). A summary of the on-site soils are provided in Table 1. Table 1: Soil Characterization Soil Symbol Soil Name Approximate Percentage of Survey Area FaB Fartmington loam, 0 to 8 percent slopes 30.0 Ma Mandalin silt loam 6.1 OaB Oakville loamy fine sand, 0 to 8 percent slopes 63.9 En Elnora loamy fine sand 0.1 3.0 METHODOLOGY 3.1 AGENCY CONSULTATION An online review of information from federal and state agencies was performed to determine what, if any, critical habitats and/or state or federally protected species exist within the Survey Area. The desktop analysis was used to develop a habitat assessment plan. 3.1.1 UNITED STATES FISH AND WILDLIFE SERVICE The United States Fish and Wildlife Service (USFWS) Environmental Conservation Online System (ECOS) Information for Planning and Conservation (IPaC) webpage was assessed. This tool was utilized to determine which federally protected species and critical habitats, if any, are potentially present within the Survey Area. 3.1.2 NEW YORK STATE DEPARTMENT OF ENVIRONMENTAL CONSERVATION The New York State Department of Environmental Conservation (NYSDEC) Environmental Resource Mapper (ERM) was searched to determine which state protected species and significant natural communities, if any, are potentially present within the Survey Area. page 3 of 7 3.2 HABITAT ASSESSMENT A habitat assessment was performed to determine whether the Survey Area contains habitat for any RTE species. The goal of the habitat assessment was to provide a characterization of the quality and quantity of habitat available to support RTE species. A desktop review of the Survey Area and information obtained from agency consultations was utilized to provide a preliminary characterization of site conditions. Information from the USFWS and NYSDEC was analyzed to identify RTE species that may be found in the vicinity of the Survey Area. Information about the type of habitat preferred by the respective RTE species was compared to the habitats observed in the Survey Area. 4.0 RESULTS 4.1 AGENCY CONSULTATION 4.1.1 UNITED STATES FISH AND WILDLIFE SERVICE On January 21, 2021, Tectonic Engineering & Surveying Consultants, P.C. (Tectonic) generated a USFWS Official Species Lists and IPaC Resource List for the Survey Area (Appendix IV). The results of the report are summarized below: Proposed, Candidate, Threatened, and Endangered Species The USFWS Official Species Lists indicated that the Survey Area may be inhabited by a total of one (1) federally protected species, including the Indiana bat (Myotis sodalis). Critical Habitats According to the USFWS Official Species List, the Survey Area does not contain any critical habitat areas. Migratory Birds According to the USFWS IPaC Resource List (Appendix IV), a total of seven (7) migratory bird species of concern may inhabit the Survey Area, including the bald eagle (Haliaeetus leucocephalus), black-billed cuckoo (Coccyzus erythropthalmus) bobolink (Dolichonyx oryvorus), canada warbler (Cardellina canadensis), prairie warbler (Dendroica discolor), snowy owl (Bubo scandiacus) and the wood thrush (Hylocichla mustelina). page 4 of 7 4.1.2 NEW YORK STATE DEPARTMENT OF ENVIRONMENTAL CONSERVATION Based on the NYSDEC Environmental Resource Mapper (ERM), the NYSDEC has no records of rare or state listed species from the Survey Area or in the vicinity of the Survey Area. According to data obtained from the NYSDEC, there is a n orthern white cedar swamp significant natural community located in the northern portion of the Survey Area, and the entire Survey Area is located in the vicinity of this significant natural community (Appendix V). 4.2 HABITAT ASSESSMENT Tectonic conducted a field assessment on December 4, 2020. The weather conditions during the field assessment were partly cloudy with temperatures ranging in the low 30 to low 40 degree Fahrenheit range. No wildlife was observed during the field assessment. Representative photographs of conditions observed during the field assessment are included in Appendix VI. Wetlands, predominantly comprised of northern white cedar swamp, red maple hardwood swamp, and shallow emergent wetlands communities, were identified in the northwestern and central portion of the Survey Area (see wetland delineation map in Appendix VII). Upland areas in the northern portion of the Survey Area adjacent to the delineated wetland areas in the northwestern portion of the Survey Area were predominantly comprised of Appalachian oak-pine forest and successional southern hardwoods ecological communities. In the southern portion of the Survey Area, a powerline right-of-way runs east- west through the Survey Area. There is a small wetland area in the southern portion of the Survey Area that is located on and adjacent to the powerline right -of-way. This wetland is comprised of shallow emergent wetland and vernal pool ecological communities. Upland areas in the southern portion of the Survey Area, as well as in the eastern portion of the Survey Area are comprised of a mosaic of successional southern hardwoods, successional shrubland, Appalachian oak-pine forest, and successional old field ecological communities. Many live trees and snags ≥5 inches dbh, some of which possess exfoliating bark, cracks crevices and/or hollows, were observed within the forested areas of the Survey Area (see aerial map in Appendix I). 5.0 DISCUSSION Indiana Bat (Myotis sodalis) The Indiana bat (IB), listed as federally endangered, is a temperate, insectivorous bat. The IB hibernates in caves or mines during winter and emerges during the spring, with males dispersing and remaining solitary or forming small bachelor groups until th e end of the page 5 of 7 summer, and pregnant females forming maternity colonies. Summer habitat of the IB generally includes wooded areas, where they roost under loose tree bark on dead or dying trees. The IB consumes a variety of flying insects found along rivers and other inland water bodies, and the IB is sensitive to forested habitat fragmentation and urbanization of habitat that was previously used for roosting. No caves or mines occur in the Survey Area. The USFWS defines suitable IB summer habitat as , “forests and woodlots containing potential roosts (i.e., live trees and/or snags ≥5 inches dbh (12.7 centimeter) that have exfoliating bark, cracks, crevices, and/or hollows), as well as linear features such as fencerows, riparian forests, and other wooded corridors” (USFWS Range-wide Indiana Bat Summer Survey Guidelines, 2017). The IB may also roost in human-made structures, such as buildings, barns, bridges, and bat houses. No caves, mines, or other potentially suitable overwintering structures occur in the Survey Area. Much of the Survey Area is forested with live trees and snags ≥5 inches dbh, some of which possess exfoliating bark, cracks crevices and/or hollows; therefore, suitable IB summer habitat is present in the Survey Area. Similar habitat is located in the Survey Area as well as to the west, south, and north of the Survey Area on adjacent parcels of land (see aerial map in Appendix I). It is anticipated that any bats living in the vicinity of the proposed project would still be able to breed, feed, and find shelter and bats would not have to fly long distances or traverse open areas to get to alternative foraging habitat. 6.0 RECOMMENDATIONS The ESA (16 U.S.C. § 1531-1544) is the federal statute designed to protect endangered and threatened fish, wildlife and plant species and the ecosystems upon which they depend. The ESA is administered by the USFWS as it pertains to terrestrial and freshwater species. Section 9 of the ESA makes it unlawful for any person or private entity to “take” individuals of an endangered species and, by regulation, a threatened species. “Take” means to “harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or attempt to engage in any such conduct.” (16 U.S.C. § 1532(19)). “Harm” includes any “significant habitat modification or degradation where it actually kills or injures wildlife by significantly impairing essential behavioral patterns, including breeding, feeding or sheltering.” (50 C.F.R. § 17.3). Based upon the preliminary review of the Survey Area and site reconnaissance, there are no documented occurrences of threatened or endangered species regulated by the NYSDEC in the Survey Area or in the vicinity of the Survey Area. Potential suitable summer habitat for the IB (trees that are 5” dbh or larger) was observed in the Survey Area. Tree clearing should be performed from November 1 – March 31, when IBs are in their hibernacula, so the project would not result in the “take” of the IB. Additionally, it is recommended that the project is designed to minimize the removal of trees live trees or snags ≥5 inches dbh that possess exfoliating bark, cracks crevices and/or hollows, to the page 6 of 7 extent feasible. The USFWS New York Field Office should be contacted to ensure that the proposed project is in compliance with USFWS threatened and endangered species regulations and would not require any additional mitigative measures. Restricting tree clearing to November 1 – March 31 would also minimize potential negative impacts to migratory birds. Precautions should be taken to minimize potential impacts to migratory birds during construction, including minimizing construction noise to the extent practicable, using care to avoid birds when operating machinery or vehicles near birds, and general contractor awareness of potential bird presence.

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.nrcs.usda.gov/wps/ portal/nrcs/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil Scientist (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/? cid=nrcs142p2_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.

They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses. 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 5 scientists classified and named the soils in the survey area, they compared the 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 Custom Soil Resource Report 6 identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately.

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 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 Custom Soil Resource Report 11 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.

A single value or rating for each map unit is generated by aggregating the interpretive ratings of individual map unit components. This aggregation process is defined for each interpretation. Land Classifications Land Classifications are specified land use and management groupings that are assigned to soil areas because combinations of soil have similar behavior for specified practices. Most are based on soil properties and other factors that directly influence the specific use of the soil. Example classifications include ecological site classification, farmland classification, irrigated and nonirrigated land capability classification, and hydric rating. Hydric Rating by Map Unit This rating indicates the percentage of map units that meets the criteria for hydric soils. Map units are composed of one or more map unit components or soil types, each of which is rated as hydric soil or not hydric. Map units that are made up dominantly of hydric soils may have small areas of minor nonhydric components in the higher positions on the landform, and map units that are made up dominantly of nonhydric soils may have small areas of minor hydric components in the lower positions on the landform. Each map unit is rated based on its respective components and the percentage of each component within the map unit. The thematic map is color coded based on the composition of hydric components. The five color classes are separated as 100 percent hydric components, 66 to 99 percent hydric components, 33 to 65 percent hydric components, 1 to 32 percent hydric components, and less than one percent hydric components. In Web Soil Survey, the Summary by Map Unit table that is displayed below the map pane contains a column named 'Rating'. In this column the percentage of each map unit that is classified as hydric is displayed. 18 Hydric soils are defined by the National Technical Committee for Hydric Soils (NTCHS) as soils that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part (Federal Register, 1994). Under natural conditions, these soils are either saturated or inundated long enough during the growing season to support the growth and reproduction of hydrophytic vegetation. The NTCHS definition identifies general soil properties that are associated with wetness. In order to determine whether a specific soil is a hydric soil or nonhydric soil, however, more specific information, such as information about the depth and duration of the water table, is needed. Thus, criteria that identify those estimated soil properties unique to hydric soils have been established (Federal Register, 2002). These criteria are used to identify map unit components that normally are associated with wetlands. The criteria used are selected estimated soil properties that are described in "Soil Taxonomy" (Soil Survey Staff, 1999) and "Keys to Soil Taxonomy" (Soil Survey Staff, 2006) and in the "Soil Survey Manual" (Soil Survey Division Staff, 1993). If soils are wet enough for a long enough period of time to be considered hydric, they should exhibit certain properties that can be easily observed in the field. These visible properties are indicators of hydric soils. The indicators used to make onsite determinations of hydric soils are specified in "Field Indicators of Hydric Soils in the United States" (Hurt and Vasilas, 2006). References: Federal Register.

The species list fulfills the requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of the Endangered Species Act (ESA) of 1973, as amended (16 U.S.C. 1531 et seq.). This list can also be used to determine whether listed species may be present for projects without federal agency involvement. New information based on updated surveys, changes in the abundance and distribution of species, changed habitat conditions, or other factors could change this list. Please feel free to contact us if you need more current information or assistance regarding the potential impacts to federally proposed, listed, and candidate species and federally designated and proposed critical habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the ESA, the accuracy of this species list should be verified after 90 days. This verification can be completed formally or informally as desired. The Service recommends that verification be completed by visiting the ECOS-IPaC site at regular intervals during project planning and implementation for updates to species lists and information. An updated list may be requested through the ECOS-IPaC system by completing the same process used to receive the enclosed list. If listed, proposed, or candidate species were identified as potentially occurring in the project area, coordination with our office is encouraged. Information on the steps involved with assessing potential impacts from projects can be found at: http:// www.fws.gov/northeast/nyfo/es/section7.htm Please be aware that bald and golden eagles are protected under the Bald and Golden Eagle Protection Act (16 U.S.C. 668 et seq.), and projects affecting these species may require development of an eagle conservation plan (http://www.fws.gov/windenergy/ eagle_guidance.html). Additionally, wind energy projects should follow the Services wind 01/21/2021 Event Code: 05E1NY00-2021-E-03586 2 ▪ energy guidelines (http://www.fws.gov/windenergy/) for minimizing impacts to migratory birds and bats. Guidance for minimizing impacts to migratory birds for projects including communications towers (e.g., cellular, digital television, radio, and emergency broadcast) can be found at: http:// www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/towers.htm; http:// www.towerkill.com; and http://www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/ comtow.html. We appreciate your concern for threatened and endangered species. The Service encourages Federal agencies to include conservation of threatened and endangered species into their project planning to further the purposes of the ESA. Please include the Consultation Tracking Number in the header of this letter with any request for consultation or correspondence about your project that you submit to our office. Attachment(s): Official Species List 01/21/2021 Event Code: 05E1NY00-2021-E-03586 1 Official Species List This list is provided pursuant to Section 7 of the Endangered Species Act, and fulfills the requirement for Federal agencies to "request of the Secretary of the Interior information whether any species which is listed or proposed to be listed may be present in the area of a proposed action".

Endangered Species Act Species There is a total of 1 threatened, endangered, or candidate species on this species list. Species on this list should be considered in an effects analysis for your project and could include species that exist in another geographic area. For example, certain fish may appear on the species list because a project could affect downstream species. IPaC does not display listed species or critical habitats under the sole jurisdiction of NOAA Fisheries , as USFWS does not have the authority to speak on behalf of NOAA and the Department of Commerce. See the "Critical habitats" section below for those critical habitats that lie wholly or partially within your project area under this office's jurisdiction. Please contact the designated FWS office if you have questions. NOAA Fisheries, also known as the National Marine Fisheries Service (NMFS), is an office of the National Oceanic and Atmospheric Administration within the Department of Commerce. Mammals NAME STATUS Indiana Bat Myotis sodalis There is final critical habitat for this species. The location of the critical habitat is not available.
