I hereby certify that I understand and agree to comply with the terms and conditions of the SWPPP and agree to implement any corrective actions identified by the qualified inspector during a site inspection. I also understand that the owner or operator must comply with the terms and conditions of the most current version of the New York State Pollutant Discharge Elimination System ("SPDES") general permit for stormwater discharges from construction activities and that it is unlawful for any person to cause or contribute to a violation of water quality standards. Furthermore, I understand that certifying false, incorrect or inaccurate information is a violation of the referenced permit and the laws of the State of New York and could subject me to criminal, civil and/or administrative proceedings. Name: Company: Title: Signature: Date: Each Sub-Contractor or additional Contractors completing site work must also sign below: Name: Company: Title: Area of Work & SWPPP Responsibilities: Signature: Date: Name: Company: Title: Area of Work & SWPPP Responsibilities: Signature: Date: Project Description The project consists of the construction of three wood framed storage buildings, with sizes of 80'x 180', 80'x 200' and 40'x 200'. Also proposed is a small expansion (20'x40') to an existing office building, asphalt surfacing and the construction of a gravel surfaced storage yard. A boundary line adjustment is proposed between the existing subject parcel (parcel 17.2) and the southerly adjoining parcel (parcel 13), in which 5.5-acres will be added to parcel 17.2, enlarging this parcel to 8.93-acres. The project is located at 27 Silver Circle and off of Big Bay Road, in the Town of Queensbury, Warren County, New York. The limit of disturbance for total build-out of the project totals 5.95-acres. Existing Site Conditions Presently, the entire project site (8.93-ac) is 25% impervious, with the front portion of the parcel containing the applicant's commercial/industrial electrical business, consisting of an office building, large warehouse building, storage yard and extensive landscaping. The rear portion of the site consists of a mixture of open, earthen surfaced space and lightly wooded evergreen forest. The existing drainage patterns for the project area are towards the southerly and westerly portions of the site, to a series of natural low areas, in which the runoff is infiltrated. Runoff from the southwesterly portion of the site flows southerly offsite. The front portion of the site in which no changes are proposed, is not evaluated in the stormwater models. Slopes over the southerly portions of the site generally range from 1-3%, from the north to the south. Site soils are mapped as Oakville loamy fine sand, HSG-A which are deep, well drained sandy soils on outwash plains. Several deep soil test pits encountered medium and coarse sands with very rapid infiltration rates.

Runoff from the two proposed northerly buildings and asphalt areas will be captured in a series of catch basins and will be piped to a vegetated pretreatment basin. Runoff from the gravel yard area and southerly building will flow to a perimeter vegetated swale, which will convey the runoff to vegetated pretreatment, which will be constructed adjacently to the south of the gravel storage yard. A catch basin with an elevated rim will be installed within the southerly pretreatment basin, which will allow the runoff to pond to the water quality volume level prior to entering the catch basin. The outlet from the catch basin will be piped into a 20'x125' subsurface stone infiltration bed, which is sized to infiltrate the 100-year design storm event. Runoff calculations have been prepared utilizing SCS TR-20 methodology and HydroCAD analysis software for the 1-year, 10-year, 50-year and 100-year Type-II simulated rainfall distributions. Criteria utilized in the analysis are summarized as follows: Design Storm Events: 1-year, 24hr, Type-II distribution, 2.2" 10-year, 24hr, Type-II distribution, 3.8" 50-year, 24hr, Type-II distribution, 4.8" 100-year, 24hr, Type-II distribution, 5.4" Proposed Conditions Calculated Runoff from the Site — Link 1 L (Easterly) 1-year design storm (2.20") 0.10 cfs 0.006 acre-feet 10-year design storm (3.80") 0.39 cfs 0.019 acre-feet 50-year design storm (4.80") 0.59 cfs 0.029 acre-feet 100-year design storm (5.40") 0.73 cfs 0.035 acre-feet Proposed Conditions Calculated Runoff from the Site- Link 2L (Westerly) 1-year design storm (2.20") 0.0 cfs 0.0 acre-feet 10-year design storm (3.80") 0.0 cfs 0.0 acre-feet 50-year design storm (4.80") 0.0 cfs 0.0 acre-feet 100-year design storm (5.40") 0.0 cfs 0.0 acre-feet Proposed Conditions Calculated Runoff from the Site- Link 3L (Southerly) 1-year design storm (2.20") 0.0 cfs 0.0 acre-feet 10-year design storm (3.80") 0.0 cfs 0.0 acre-feet 50-year design storm (4.80") 0.0 cfs 0.0 acre-feet 100-year design storm (5.40") 0.0 cfs 0.0 acre-feet Proposed Conditions Calculated Runoff from the Site-Link 4L (Southeasterly) 1-year design storm (2.20") 0.0 cfs 0.0 acre-feet 10-year design storm (3.80") 0.0 cfs 0.0 acre-feet 50-year design storm (4.80") 0.0 cfs 0.0 acre-feet 100-year design storm (5.40") 0.0 cfs 0.0 acre-feet Proposed Conditions Calculated Runoff from the Site-Total Site Runoff 1-year design storm (2.20") 0.10 cfs 0.006 acre-feet 10-year design storm (3.80") 0.39 cfs 0.019 acre-feet 50-year design storm (4.80") 0.59 cfs 0.029 acre-feet 100-year design storm (5.40") 0.73 cfs 0.035 acre-feet The developed site has been modeled as a series of subcatchments (drainage areas) and ponds, as shown on the HydroCAD drainage diagram. Full results of stormwater runoff computations are attached to this report. The results of the stormwater models show that the proposed vegetated pretreatment practices and infiltration bed are of adequate capacity to receive runoff from the 100-year storms without overflowing and provide rate and volume reductions for the`design storms. Water Quality Volume The water quality volume (WQv) as required by NYSDEC is designed to capture and pre-treat the 90% rainfall event and is calculated as a function of the impervious areas of the drainage subcatchments for the project site. Subcatchment Required Provided Location 1S 11,220CF 11,230CF - 1P 1P 7150 CF 3S 7105 CF (3190 CF-3P, 3P, 1 P 3960 CF- 1 P) Note: A total of 15,190 CF of storage is provided in 1 P below the catch basin rim. Runoff Reduction Volume The runoff reduction volume (RRv) as required by NYSDEC has the design goal to reduce the calculated WQv through approved "green infrastructure practices" or infiltration practices. As the entire 100-year design storm is infiltrated in the subsurface infiltration bed, the RRv design goals are met. Channel Protection Volume Channel protection volume (Cpv) as required by NYSDEC requires the extended detention or infiltration of the post-developed 1-year, 24-hour storm. Subcatchment Reouired Provided Location 1S 1570 CF Infiltrated 1AP 3S 8495 CF Infiltrated 1AP Overbank Flood Control Overbank flood control as required by NYSDEC requires that the peak developed discharge rate from the 10-year, 24-hour storm not exceed the pre-development rate. Existing peak 10-year storm discharge: 0.76 CFS Proposed peak 10-year storm discharge: 0.39 CFS The 10-year storm calculations show that the overbank flood control requirement is met. Extreme Storm Control Extreme storm control as required by NYSDEC requires that the peak developed discharge rate from the 100-year, 24-hour storm not exceed the pre-development rate. Pre-developed peak 100-year storm discharge: 5.39 CFS Developed peak 100-year storm discharge: 0.73 CFS The 100-year storm calculations show that the overbank flood control requirement is met. Town of Queensbury Requirement The Town of Queensbury requires that the peak developed discharge rate from the 50- year, 24-hour storm not exceed the pre-development rate. Pre-developed peak 50-year storm discharge: 1.89 CFS Developed peak 50-year storm discharge: 0.59 CFS The 50-year storm calculations show that the Town of Queensbury requirement is met. Endangered Species In accordance with Part I.D.4 of GP-010-0-001, an inquiry was made to NYSDEC for an endangered species impact determination. A letter of no impact upon endangered species from NYSDEC which was received for a previously proposed project upon the southerly parcels 12 &13 is included as an attachment in this report. Parcel 17.2 is fully developed and contains a large, existing commercial/industrial electrical business. The portions of this project which will occur upon parcel 17.2 will be situated over previously disturbed areas, thus there will be no impact upon endangered species on this parcel. Archaeological Resources and Historic Places In accordance with Part III.A.8 of GP-010-0-001, a letter of no impact upon archaeological resources from NYSOPRHP which was received for a previously proposed project upon the southerly parcels 12 &13 is included as an attachment in this report. As disturbances upon parcel 17.2 will occur over previously disturbed areas, there will be no impact upon cultural resources on this parcel. Construction Phase Erosion Practices Practices to be implemented during construction for erosion and sediment control include silt fencing and temporary sediment basins in various portions of the total disturbed area. Silt fencing will be placed across slopes (on the contour) in all areas downgrade of disturbed areas. Temporary sediment traps will be utilized in areas where construction phase runoff concentrates. Temporary Erosion and Sediment Control Measures Erosion and sediment control measures will be incorporated into the construction of the project. These practices will comply with the New York State Department of Environmental Conservation publication entitled "New York Guidelines for Urban and Sediment Control' (the blue book). The following temporary erosion and sediment control devices are to be utilized: Sediment Control Fence Silt Fence shall be used to control erosion from sheet flow on slopes not to exceed 1 on 3. Concentrated flows shall not be directed toward the silt fence. The silt fence must be installed parallel to the contour lines to eliminate drainage along the fence. Temporary Sediment Basin Basins will be excavated below each house site and seeded with ryegrass to accept stormwater runoff from the construction site allowing sediment to settle out. Sediment traps shall be constructed in the location and be of the size and type specified to collect sediment laden stormwater. Temporary Seeding Land that is stripped of vegetation will be seeded and planted as soon as possible. Any area that will remain cleared but not under construction for 10 days or longer will be seeded with a ryegrass mixture and mulched to stabilize soil until construction resumes. Temporary Diversion Swales Temporary diversion swales shall be constructed either to divert clean stormwater runoff from newly graded areas or to direct sediment laden runoff to a sediment trapping device. Dust Control Measures for dust control during construction shall be implemented as needed. Daily water sprays will be used during dry conditions. In addition to water sprays, temporary mulching, temporary seeding and covering stockpiles with tarps shall be implemented when necessary. Control of Litter. Construction Debris and Construction Chemicals During the course of construction, the site shall be kept clear of debris and litter which could be transported by water or wind. This material shall be picked up daily and shall be stored in waste debris containers where it will be securely held. All petroleum products or other waste contaminants which are water soluble, or could be dispersed and transported by stormwater, shall be stored in covered containers and be regularly removed from the site and properly and legally disposed of. All petroleum or other hazardous materials shall be stored and handled in conformance with NYSDEC spill prevention and containment requirements. Sequence of Construction Prior to the start of construction, the contractor shall install the sediment control fence along the low side of each area to be disturbed to contain runoff from the construction site. Temporary sediment basins are to be constructed as shown on the plans and shall collect stormwater runoff from all areas of proposed road and utility construction. The temporary sediment basins shall be a minimum of 3600 CF per acre of disturbance. Basins shall allow collected water to filter into the existing soil; if necessary, sediment will be cleaned out of the basins to maintain their infiltrative capability. Following the completion of all planting and the establishment of all grass areas, any collected sediment and sediment control fencing shall be removed. Any debris from the perimeter of the site shall be removed and dispose of all waste material shall be disposed of in a legal manner. Maintenance of Temporary Erosion & Sediment Control Devices The sediment basins shall be inspected at least weekly and after every rain event by the contractor. When 50% of the volume of the basin is full, the contractor shall remove collected sediment and dispose of properly. The contractor shall inspect the sediment control fence weekly and after every rain event and remove trapped sediment and maintain the devices such that they are in good working order. Operation and Maintenance Plan The property owner and their successors will be responsible to provide the maintenance in the forebay, retention areas and stormwater structures. Maintenance includes trimming of vegetation in the forebay and retention areas and sediment removal in the stormwater structures. Trimming should be performed as needed throughout the spring, summer and fall, typically monthly or semi-monthly. Sediment removal and inspection of the stormwater infrastructure should be performed annually. Permanent Erosion Control All pervious areas shall be graded, topsoil installed and seeded or planted as soon as practical, but in no case shall finish graded soils be exposed for more than five days. Seed beds shall be mulched with straw and plant beds shall be mulched with pine bark mulch. Seeded areas on slopes over 1:3 shall be stabilized with erosion control blankets as specified on the plans.
