BES Design/Build, LLC I 766 Middle Street, Fairhope, AL. 36532 I PH: 251-990-5778 I FX: 251-990-3716 attached site plan. The project is located adjacent to building #11010 along Iraqi Freedom Drive and will disturb approximately 1.43 acres.

This SWPPP covers all site development and is scheduled to be completed by 2017.

Project Disturbance Area

Total Disturbed Area: ±1.43 acres

Proposed Total Impervious Area: ±0.40 acres (0.16 of which was previously impervious)

Site Soil Descriptions

The soil disturbance for the proposed work is limited to 1.43 ± acres within the property boundary.

The site is undisturbed and covered with tree vegetation. According to the USDA Soil Survey of

Jefferson County, New York, the area of disturbance consists primarily of Hudson silt loam (HuB)

(see Appendix A).

The Natural Resource Conservation Service (NRCS, formerly known as the SCS), as part of their soil classification system, assigns each soil series to a Hydrologic Soil Group (HSG). The HSG is a four-letter index intended to indicate the minimum rate of infiltration obtained after prolonged wetting, and to indicate the relative potential for a soil type to generate runoff. The infiltration rate is the rate at which water enters the soil at the soil surface. The HSG also indicates the transmission rate – the rate at which water moves within the soil. Soil scientists define the four groups as follows:

HSG ‘A’ (sand, loamy sand, or sandy loam): Soils have low runoff potential and high infiltration rates even when thoroughly wetted. They consist chiefly of deep, well to excessively drained sands or gravels and have a high rate of water transmission (> than 0.30 inches/hour).

HSG ‘B’ (silt loam or loam): Soils have moderate infiltration rates when thoroughly wetted, and consist chiefly of moderately deep to deep, moderately well to well drained soils with moderately fine to fine texture. These soils have a moderate rate of water transmission (0.15 to 0.30 inches/hour).

HSG ‘C’ (sandy clay loam): Soils have low infiltration rates when thoroughly wetted and consist chiefly of soils with a layer that impedes downward movement of water, and soils with moderately fine to fine texture. These soils have a low rate of water

HSG ‘D’ (clay loam, silty clay loam, sandy clay, silty clay, or clay): Soils have high runoff potential. They have very low infiltration rates when thoroughly wetted, and consist chiefly of clay soils with a high swelling potential, soils with a permanent high water table, soils with a clay pan or clay layer at or near the surface, and shallow soils over nearly impervious material. These soils have a very low rate of water transmission (< 0.05 inches/hour).

If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in Group D are assigned to dual classes.

Hudson silt loam are classified as HSG B soils.

Historic

The proposed project will have no adverse impact on a property that is eligible for listing on the

State or National Register of Historic Places in Jefferson County, New York. This is confirmed via the Cultural Resource Information System (CRIS) online at https://cris.parks.ny.gov/ searched

CHAPTER 03

Construction

Sequence

This SWPPP presents erosion and sediment controls, both temporary and permanent, to assist the operator in compliance with the project’s SPDES General Permit for construction activity. To the degree practicable, all temporary erosion and sediment control mitigation measures shall be installed immediately before associated project areas are disturbed in anticipation of all soil disturbing activities to follow. Based upon NYS DEC regulations, the owner or operator of a construction activity shall not disturb greater than five (5) acres of soil at any one time without prior written authorization from the Department or, in areas under the jurisdiction of a regulated, traditional land use control MS4, the MS4 (provided the MS4 is not the owner or operator of the

BES Design/Build, LLC I 766 Middle Street, Fairhope, AL. 36532 I PH: 251-990-5778 I FX: 251-990-3716 construction activity). At a minimum, the owner or operator must comply with the following requirements in order to be authorized to disturb greater than five (5) acres of soil at any one time:

1. The owner or operator shall have a qualified inspector conduct at least two (2) site inspections in accordance with Part IV.B. every seven (7) calendar days, for as long as greater than five (5) acres of soil remain disturbed. When performing just two (2) inspections every seven (7) calendar days, the inspections shall be separated by a minimum of two (2) full calendar days.

2. In areas where soil disturbance activity has been temporarily or permanently ceased, temporary and/or permanent soil stabilization measures shall be installed and/or implemented within seven (7) days from the date the soil disturbance activity ceased. The soil stabilization measures selected shall be in conformance with the most current version of the technical standard, New York Standards and Specifications for Erosion and Sediment Control.

3. The owner or operator shall install any additional site specific practices needed to protect water quality.

4. The owner or operator shall include the requirements above in their SWPPP.

It is the responsibility of the Contractor to ensure that all soils removed from the project site are spoiled in a manner consistent with all local, state, and federal regulations. Appropriate erosion and sediment controls shall be installed at all spoil sites. Additionally, the Contractor is responsible for coordinating the application for a GP- 0-15-002 permit (and development of an associated

SWPPP) if disturbance associated with any soil spoils area is greater than 0.4 hectares (1 acre).

GP-0-15-002 applications must be signed by the owner of the lands on which soils are spoiled.

Disturbances associated with offsite spoil areas do not contribute to the total disturbances associated with onsite activities.

It is not anticipated to disturb greater than 5 acres of land at one time for this project. See construction documents for sequencing information.

Streams

Stormwater runoff generally drains to the southwest discharging to West Creek (Class A, Standards A) which is a second order stream or larger.

CHAPTER 04

Controls

Timing of Controls / Measures

The erosion and sediment control measures shall be constructed prior to clearing or grading of any portion of the project. Where land disturbance is necessary, temporary seeding or mulching must be used on areas which will be exposed for more than 14 days. Permanent stabilization should be performed as soon as possible after completion of grading. After the entire project area is stabilized, the accumulated sediment shall be removed from the project area. Erosion control devices shall remain in place until disturbed areas are permanently stabilized. For projects where soil disturbance is greater than five (5) acres, and construction activity has temporarily or permanently ceased, temporary and/or permanent soil stabilization measures shall be installed and/or implemented within seven (7) days from the date the soil disturbance activity ceased. The soil stabilization measures selected shall be in conformance with the most current version of the technical standard, New York Standards and Specifications for Erosion and Sediment Control.

Erosion and Sediment Control Plan

Temporary Stabilization

Topsoil stockpiles, staging areas and disturbed pervious portions of the project area where construction activity temporarily ceases for at least 14 days shall be stabilized with temporary seed and mulch no later than 14 days from the last construction activity in that area.

Temporary seed shall be ryegrass applied at the rates specified below:

If seeding in spring, summer or early fall then seed with annual or perennial rye at a rate of 30 lbs per acre. If area is to remain stabilized over the winter into the following spring use perennial rye only.

If seeding in late fall or early winter, use certified Aroostook winter rye (cereal rye) at a rate of 90 lbs per acre.

Any seeding method may be used that will provide uniform application of seed to the area and result in relatively good soil to seed contact. Area must be free of large rocks and debris and seeded within 24 hours of disturbance or scarification of the soil surface will be necessary prior to seeding. Fertilizer or lime is not typically used for temporary plantings.

BES Design/Build, LLC I 766 Middle Street, Fairhope, AL. 36532 I PH: 251-990-5778 I FX: 251-990-3716

Mulch shall be applied in conjunction with seeding and applied at the rate of 90 lbs per 1,000 square feet. Mulch shall be reapplied as necessary. Areas of the project area, which are to be paved, shall be temporarily stabilized by applying temporary gravel subbase until pavement can be applied.

Sediment control fencing shall be installed around the site where depicted on the attached plan sheets. Additional fencing shall be installed as necessary.

Permanent Stabilization

Disturbed portions of the project area where construction activities permanently cease shall be stabilized with permanent seed no later than 14 days after the last construction activity. The permanent seed mix shall be in accordance with the project specifications and plans. Construction and maintenance of erosion and siltation control measures are in accordance with the New York

Standards and Specifications for Erosion and Sediment Control.

Where construction activity is complete over areas to be permanently vegetated, stabilize with permanent seeding. Verify seeding dates with engineer. If engineer determines that seed cannot be applied due to climate, topsoil shall not be spread and mulching shall be applied to the exposed surface to stabilize soils until the next recommended seeding period. Other project areas shall be permanently stabilized with pavement, concrete, gravel or building structures.

Winter Operations

If construction activities proceed through the winter season, access points should be enlarged and stabilized to provide for snow stockpiling. Drainage structures should be kept open and free of potential snow and ice dams. Inspection and maintenance are necessary to ensure the function of these practices during runoff events. For sites where construction activities temporarily cease, temporary and/or permanent soil stabilization measures shall be installed within seven (14) days from the date the soil disturbing activity ceased. Disturbed areas should be stabilized with seed and mulch, or other approved methods, even if the ground is covered by significant amounts of snow.

Winter Shutdown

Site inspections (by the qualified inspector) may be decreased to a minimum of one (1) time every thirty (30) days for sites where soil disturbing activities have ceased and the site has been completely stabilized with an approved method. Inlet protection should be installed and/or

Other Controls

Waste Disposal

Waste materials – Foreign waste materials shall be collected and stored in a secured area until removal and disposal by a licensed solid waste management company. All trash and construction debris from the project area shall be disposed of in a portable container unit. No foreign waste materials shall be buried within the project area. All personnel shall be instructed regarding the correct procedure for waste disposal. Notices stating these practices shall be posted in the project trailer and the individual who manages day-to-day project operations will be responsible for seeing that these procedures are followed.

Petroleum Impacted Waste – During the excavation activities, there is the potential that petroleum impacted soils may be encountered. In the event that field evidence of contamination is identified during the project, potentially contaminated soils will be segregated and stockpiled on polyethylene sheeting and covered in a predetermined staging area. The potentially impacted, stockpiled soils will then be sampled to determine if the soils are suitable for use as clean backfill. In the event that the soils are not suitable for re-use, the contaminated soil will be properly characterized and disposed of at an off-site NYSDEC permitted facility. The excavation will then be backfilled with clean, imported fill.

Hazardous Waste - All hazardous waste materials shall be disposed of in a manner specified by local or state regulations or by the manufacturer. Project personnel shall be instructed in these practices and the individual who manages day-to-day project operations shall be responsible for seeing that these practices are followed.

Sanitary Waste - Any sanitary waste from portable units shall be collected from the portable units by a licensed sanitary waste management contractor, as required by NYS DEC regulations.

Vehicle Tracking

A stabilized construction entrance shall be installed and maintained as necessary to help reduce vehicular tracking of sediment should the potential for sediment tracking exist. The entrance shall be cleaned of sediment and redressed when voids in the crushed stone become filled and vehicular tracking of sediment is occurring. Dump trucks hauling materials to and from the construction project area shall be covered with a tarpaulin to reduce dust. Any sediment and debris tracked from work area along project adjacent roadways shall be immediately removed with a street sweeper or equivalent sweeping method. Further, sweeping of streets adjacent to disturbed

Other Discharges

Non-stormwater discharges are not expected to exit the project area during construction.

Certification of Compliance with Federal, State, and Local Regulations

The stormwater pollution prevention plan reflects the New York State requirements for stormwater management and erosion and sediment control. Even though permit coverage is not required due to the direct discharge to the combined sewer system, Federal regulations require the project to be designed as if State regulations applied. To ensure compliance, this plan was prepared in accordance with New York State Standards. There are no other applicable State or Federal requirements for sediment and erosion plans (or permits), or stormwater management plans (or permits).

CHAPTER 05

Post-Construction Stormwater Management

Water Quality

Water quality treatment will be designed to capture and treat 90% of the annual stormwater runoff volume, or the full water quality volume (WQv) for the new impervious surfaces. Treatment practices need to be capable of 80% Total Suspended Solids (TSS) removal and 40% Total

Phosphorous (TP) removal, have an accepted longevity in the field and have a pretreatment mechanism.

Per Chapter 9 of the New York State Stormwater Management Design Manual (NYSSMDM), the project falls within the Redevelopment guidelines. Therefore, 25% of the Water Quality Volume

(WQv) is required to be treated for existing impervious surfaces, while 100% is required for new impervious surfaces.

Pre-Development Site Conditions

The existing topography of the site is rolling terrain with swales that capture storm water runoff varying in slope from 3% to 7% while varying in elevation from 483 ft. to 465 ft. The site generally drains towards the project and out to eventually outfall to West Creek to the west. The site is undisturbed covered with tree vegetation. The predominant soil type in this area is glacial till consisting of Hudson silt loam, 3 to 8 percent slopes with an infiltration rate potentially as low as 16 in/hr. Proposed grades will accommodate the UFC regulations regarding minimum and maximum slopes for both grading of building frontage and within the proposed parking facilities addition. The stormwater management for the site will be accomplished through a combination of overland flow, infiltration beds in the ditches, bio-retention basin, and a parking filtration strip along the parking lot as per the UFC 3-210-10, Low Impact Development Manual. The bio-retention basin will be located near the low point just south of the parking area. The total land disturbance is approximately 1.43 acres; while the total drainage area of the site is 2.4 acres.

Post Development Conditions

The site will be cleared of trees, re-graded to suit the design requirements and parking and building expansion will be added. The total disturbed area is approximately 1.43 acre therefore a Notice of Intent will be filed to gain coverage under the NYSDEC SPDES General Permit (GP

0-015-002). New impervious area added will include asphalt pavement, concrete sidewalks, canopy, and new building expansion. The total new impervious area added will be 0.40 acres.

The new design will direct the existing swale into roadside ditches on both sides of the road and direct it to the outfall. In order to meet low impact development requirements outlined in UFC 3-

210-10, roadside ditches will be four feet wide with infiltration trenches, and a bio retention pond will be constructed near the outfall at station 11+00 left side. The parking lot will sheet flow over the pavement to the ditch to allow more infiltration time. The parking lot will also include a stone filter diaphragm at the edge of pavement to help absorb and filter the runoff. The entire site will be seeded and trees will be added to further reduce the impacts of the cleared site.

Low Impact Development Features

In order to achieve and reduce post development runoff at least the pre-development characteristics of the site will be maintained after development and the following design features will be implemented.

Infiltration ditches---Added into the roadside ditches. This will filter the water and reduce the volume

Bio-retention bed---This will detain the water, filter the water and reduce the volume through infiltration and plant absorption

Calculations for Determining Water Quality Treatment and Runoff Reduction Volumes-Infiltration Trenches

Calculations for water quality runoff and reduction are based on New York State Stormwater

Management Design Manual 2015 chapter 4 and 9. This is considered a redevelopment project due to it being an existing site that we are adding new impervious area to. Because of this, the site will have an increase in runoff. The existing impervious area consists of a building, asphalt parking lot and concrete sidewalk totaling 0.16 acres. The new construction will include an addition to the building, expanded parking, and additional pavement for the access road and a search canopy. Post construction impervious area is 0.40 acres. The redevelopment guidelines for treatment require treating 25% of the water volume for existing impervious areas and 100% treatment for new impervious areas; Chapter 9 page 9-5. The treatment will be handled by 4’ wide x 4’ deep stone filled infiltration trenches and bio-retention. The formulas used are from Chapter

4 and 6 of the sited manual.

CHAPTER 06

Maintenance / Inspection Procedures

Erosion and Sediment Control Inspection and Maintenance Practices

These are the minimum required inspection and maintenance practices that shall be used to maintain erosion and sediment controls:

Owner/Operator Inspection Requirements

Prior to construction activity the owner/operator shall have contractors and sub-contractors identify a trained individual responsible for the implementation of the SWPPP. The trained individual must be on-site on a daily basis when soil disturbing activities are occurring.

The owner/operator shall inspect the erosion and sediment control measures as identified in the SWPPP to ensure that they are being maintained in effective operating conditions at all times. Where soil disturbing activities temporarily cease (e.g. winter shutdown) and temporary stabilization measures have been applied to all disturbed areas, the owner/operator can stop conducting inspections. The owner/operator shall resume inspections when soil disturbing activities begin again.

Where soil disturbing activities have ceased with partial project completion, the owner/operator can stop conducting inspections when disturbed areas have reached final stabilization. All post construction stormwater management practices required for the completed areas shall have been constructed in conformance with the SWPPP and be fully operational. Final stabilization means that all soil disturbance activities have ceased and a uniform, perennial vegetative cover with a density of eighty (80) percent over the entire pervious surface has been established; or other equivalent stabilization measures, such as permanent landscape mulches, rock rip-rap or washed/crushed stone have been applied on all disturbed areas that are not covered by permanent structures, concrete or pavement.

The owner/operator shall notify the DEC Regional Office’s and Fort Drum’s stormwater contact person prior to any reduction in the frequency of site inspections.

The owner/operator shall retain copies of the NOI, NOI acknowledgment letter, SWPPP, MS4 SWPPP acceptance forms and any inspection reports submitted in conjunction with

Preface

Soil surveys contain information that affects land use planning in survey areas. 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 (http:// 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.
