Stormwater Pollution Prevention Plan Introduction

USACOE 1-1 Burns & McDonnell

1.0 INTRODUCTION

The U.S. Environmental Protection Agency (EPA) requires a National Pollutant Discharge Elimination

System (NPDES) Permit for stormwater discharges from construction activities that disturb 1 or more acres of land or from smaller sites that are part of a larger, common plan of development or sale which will disturb a cumulative total of 1 or more acres. For the purpose of the NPDES program, construction activities are defined as clearing, grading, excavation, and other construction-related activities that could lead to the generation of pollutants.

In the State of Massachusetts, Region 1 of the EPA is the permitting authority for the NPDES program.

Construction projects that will disturb 1 or more acres of land are issued a certificate of permit coverage under EPA General Permit MAR100000 (Permit), which authorizes the discharge of stormwater associated with construction activities into State waters. Stormwater discharges from construction activities associated with the Regional Isochronal Inspection (ISO) Maintenance Hangar Project (Project) for the Louisville District U.S. Army Corps of Engineers (USACE) are authorized under the Permit. The

Permit is issued pursuant to the Clean Water Act as amended (33 U.S.C. 1251 et. seq.). A copy of the

Permit is provided in Appendix A.

Coverage under the Permit is obtained by developing a Stormwater Pollution Prevention Plan (SWPPP) and then submitting a Notice of Intent (NOI) through the EPA’s NPDES eReporting Tool (NeT) at http://www.epa.gov/npdes/stormwater-discharges-construction-activities#ereporting. The NOI authorization will be included in Appendix B once received. The SWPPP described herein establishes a plan to manage the quality of stormwater runoff from construction activities associated with the Project.

This SWPPP has been developed in accordance with requirements and guidelines specified in Part 7 of the Permit. The SWPPP was also written with the assistance of and information from the EPA’s 2007

Developing Your Stormwater Pollution Prevention Plan: A Guide for Construction Sites.

This SWPPP must be used by onsite construction personnel to reduce soil erosion and to minimize the potential for sediment and other onsite pollutants to leave the Project site and enter waters of the State of

Massachusetts. The SWPPP identifies a set of best management practices (BMPs) to be implemented on the Project site; however, BMPs may need to be moved, added, or redesigned to control erosion and sedimentation to the extent practicable. The SWPPP must be updated and revised when stormwater control measures are modified due to a change in design, construction method, operation, maintenance procedure, etc.

USACOE 1-2 Burns & McDonnell

1.1 Project Description and Location

The Project will consist of the construction of a new C-5 ISO Maintenance Hangar facility at the

Westover Air Reserve Base. This project is located to along the eastern aircraft apron and will require some repaving of the existing apron. The site work includes new access drives, a parking lot, sidewalks, new security fencing, and all utilities to support the new hangar. A new fuel station will be constructed in a new location to replace the existing airside fuel station. The project also includes work to demolish an existing facility on-site, Building 2426. A General Vicinity Map showing the location of the Project can be found in Appendix C. The Project is located in Chicopee, Hampden County, Massachusetts

(42.193313, -72.545387). Construction is scheduled to begin in January 2020 and be completed by

January 2022.

Approximately 6.5 acres of the 8.2-acre site will be disturbed. Based on an evaluation of the Project site, the pre-development percent imperviousness for the Project is 64 percent, and the post-development percent imperviousness is expected to increase to 74 percent. This SWP3 has been developed to address all construction activities associated with the Project.

1.2 Project Owner and Operator

Contact information for the Project owner, USAF Westover Air Reserve Base, is provided below.

USAF Westover Air Reserve Base Rick Colburn 975 Patriot Avenue Chicopee, MA 01022 (413)-557-2433

An operator is any person associated with the Project that has operational control over the construction plans and specifications, including the ability to make modifications to the plans and specifications, and any person who has day-to-day operational control over the construction activities and can make necessary decisions to maintain compliance with Permit conditions. Where there are multiple operators associated with the same project, all operators are required to obtain Permit coverage. All operators must submit an NOI and sign the Operators Certification form, provided at the front of this SWPPP, in accordance with Appendix J of the Permit. Contact information for the Project operator(s) will be added to this SWPPP when available.

1.4 SWPPP Certification

By signing the Contractor Notification form (located near the front of this document, copy as needed), the contractor and subcontractors signify they have read, understand, and will adhere to the SWPPP before conducting any construction work that will result in land disturbance. The signed certification confirms that USACE has notified the contractor or subcontractors that a SWPPP has been prepared for the Project, and the contractor and subcontractors must perform the necessary actions identified to comply with the

SWPPP and the Permit. To maintain compliance with the Permit, it may be necessary for the contractor or subcontractor responsible for erosion and sediment control to implement additional stormwater BMPs and pollution prevention measures that may not be indicated in this SWPPP.

1.5 Standard Permit Conditions

This section discusses Federal penalties for noncompliance with the Permit, as well as standard Permit conditions. The staff responsible for implementation of the SWPPP must be familiar with the requirements of the SWPPP and the Permit.

1.5.1 Duty to Comply with Permit Conditions

The EPA has substantial penalties for noncompliance with the Permit. USACE has a duty to comply with

Permit conditions. Failure to comply with Permit conditions is a violation of the Permit and statutes under which it was issued and is grounds for enforcement action including terminating Permit coverage, modification of Permit coverage, or denial of the Permit renewal application, as well as potential criminal, USACOE 1-4 Burns & McDonnell civil, and administrative penalties. Those responsible for SWPPP implementation must be familiar with the SWPPP and Permit requirements.

The EPA, or an authorized representative of the EPA, must be allowed onto the Project site and any location where records are kept under the conditions of the Permit. The EPA must also be allowed to inspect the Project site, sample or monitor stormwater discharges, and access and copy any required records. USACE must comply with any corrective actions required by the EPA as a result of Permit violations discovered during an inspection.

1.5.2 Notice of Permit Coverage Posting Requirements

A Notice of Permit Coverage (Appendix D) must be posted at the entrance to the Project site. It must be visible from a public road, and the font must be large enough to be readily viewed from the public right-of-way.

1.5.3 Modification of NOI

If a modification to the NOI is necessary, due to changes to the Project (e.g., the extent of disturbance has increased), a Change NOI must be submitted using EPA’s NeT. The amendment must include the

Project’s assigned permit number and the requested change. The SWPPP must be updated to reflect the modification(s).

1.5.4 SWPPP Modifications

This SWPPP must be modified, including site maps, within 7 days of any of the following conditions:

• A new operator becomes active onsite; changes are made to construction plans and erosion and sediment control BMPS; or other activities onsite are no longer accurately reflected in this

SWPPP.

• Operational control over areas of the Project site have transferred to another operator.

• State or Federal officials determine SWPPP modifications are necessary for Permit compliance, following onsite inspections.

• The EPA decides to impose additional requirements on the stormwater discharge.

• Revisions to applicable Federal, State, or local requirements affect the stormwater control measures implemented at the Project site.

1.5.5 Final Stabilization and Termination of Coverage

For any areas not covered by permanent structures, final stabilization is met when the Project has been seeded or planted to establish a uniform perennial vegetative cover that will provide a density of 70

USACOE 1-5 Burns & McDonnell percent of the native background vegetative cover for the area. In addition, construction materials, equipment, and waste have been removed from the Project site, and pollutant generating activities associated with construction activities have ceased.

Permit coverage is terminated by submitting a Notice of Termination (NOT) via the EPA’s NeT within 30 calendar days of final stabilization and completeness of the Project.

1.5.6 Retention of Records

The SWPPP and a copy of the authorized NOI must be maintained at the appropriate Project construction office from the date of Project initiation to the date of Project completion. Records must be maintained for dates when major grading occurs, construction activities temporarily or permanently cease, stabilization measures are initiated, and final stabilization is achieved. The following records must be retained for a minimum period of 3 years from the date that Permit coverage expires or is terminated:

• The SWPPP and any amendments to the SWPPP

• A copy of the Permit, the signed and certified NOI submitted to the EPA, and the acknowledgement letter from the EPA’s NeT assigning the NPDES identification number

• Data used to complete the NOI

• Reports and actions required by the Permit

• Site inspection records

• Corrective action reports

• Contractor certifications

• Clearance letters from the U.S. Fish and Wildlife Service (USFWS), Massachusetts Department of Fish and Game, Massachusetts State Historic Preservation Office, the U.S. Army Corps of

Engineers, and any other agency providing clearance

• A copy of the NOT submitted to the EPA

2.5 Potential Pollutants

The primary pollutant sources on the Project site will be disturbed soils and subsequent stormwater runoff caused by grading and site excavation operations, vehicle tracking, soil stockpiling, and debris from demolition work. BMPs must be used on the Project site to control erosion and minimize offsite sedimentation. Erosion and sediment control BMPs are discussed in further detail in Chapter 3.0 of this

SWPPP. BMPs for product specific practices are discussed in Chapters 5.0 and 7.0.

Non-stormwater discharges from active construction sites are authorized if the discharge complies with

Part 1.2.2 of the Permit. During Project construction, the following discharges may occur:

• Fire hydrant flushings

• Discharges from emergency fire-fighting activities

• Water used to wash vehicles and equipment, provided there is no discharge of soaps, solvents, or detergents

• Landscape irrigation

• Water used to control dust

• Uncontaminated and non-turbid discharges of groundwater or spring water

• Potable water, including uncontaminated waterline flushing

• Routine external building washdown, provided there is no discharge of soaps, solvents, or detergents and the external surfaces do not contain hazardous substances

• Pavement wash waters where spills or leaks of toxic or hazardous materials have not occurred

(unless all spilled material has been removed) and where soaps, solvents, or detergents have not been used

• Foundation or footing drains where flows are not contaminated with process materials such as solvents

• Construction dewatering water discharges in accordance with Part 2.4 of the Permit

• Uncontaminated air conditioning or compressor condensate

2.6 Receiving Waters

Stormwater runoff will drain to the Westover ARB Municipal Separate Storm Sewer System (MS4). Inlet protection and other BMPS will be installed during construction to collect sediment and other construction-related pollutants before they enter the storm sewer system.

USACOE 2-3 Burns & McDonnell

2.7 Threatened and Endangered Species

According to the USFWS Information for Planning and Consultation (https://ecos.fws.gov/ipac/ accessed on April 25, 2019), two federally listed threatened species, the northern long-eared bat (Myotis septentrionalis) and the small whorled pogonia (Isotria medeoloides), are listed as potentially occurring near the Project site. As per coordination with base environmental personnel, no impacts to threatened and endangered species are expected.

2.8 Cultural Resources

According to the National Register of Historic Places

(https://www.nps.gov/maps/full.html?mapId=7ad17cc9-b808-4ff8-a2f9-a99909164466, accessed on April

25, 2019), no historic properties are located on or within 1,000 feet the of Project site. Additionally, no architectural properties are listed on or nominated for inclusion in the National Register of Historic

Places. While cultural resources are not anticipated in the area of disturbance, workers must stop work immediately and notify USACE and the construction office upon discovery of items with potential historical significance, including but not limited to arrowheads, bones, old bottles or building materials, building foundations, and suspected gravesites. If human remains are unearthed during excavation work, then the area must be secured, and the local law enforcement agency must be contacted immediately.

Stormwater Pollution Prevention Plan Controls - Structural Practices

USACOE 3-1 Burns & McDonnell

3.0 CONTROLS - STRUCTURAL PRACTICES

The following sections detail the structural erosion and sediment control BMPs that must be implemented prior to the start of major earth-disturbing activities on the Project site.

3.1 Temporary Erosion and Sediment Control Practices

Erosion and sediment control BMPs must be in place prior to soil-disturbing activities and must be maintained throughout construction. To limit the potential for sediment leaving the Project site, erosion and sediment control BMPs may be required in other locations of the Project site as work progresses.

These BMPs must be evaluated by the contractor/owner’s representative in the field; if measures are changed, then the SWPPP must be modified in accordance with Chapter 6.0 of this document. The minimum temporary erosion and sediment control BMPs that will be used for the Project are discussed in the following subsections.

3.1.1 Construction Entrance

Offsite tracking of soils must be limited by utilizing an appropriately designed construction entrance. The construction entrance installed on the Project site must be maintained throughout the duration of construction. If necessary, a culvert will be installed to allow stormwater to pass under the construction entrance. The amount of sediment that is transported onto a public road surface or other paved areas by construction equipment or vehicles must be limited and cleaned up at the end of each work day. The location and installation details for the construction entrance are provided in Appendix E and F, respectively.

3.1.2 Silt Fence

Silt fence will be used to intercept and retain sediment carried by sheet flow from disturbed areas and to limit sediment-laden runoff from leaving the Project site during construction. Silt fence should be placed perpendicular to the direction of water flow and as close to topographic contours as possible, with the ends extending upslope. Silt fence should also be placed downslope of disturbed areas where sheet or rill erosion would occur and around soil stockpiles. Silt fence must be inspected and maintained on a regular basis, and sediment buildup must be removed when sediment reaches 50 percent of the height of the barrier. Silt fence may be installed with an additional wire backing to provide extra strength in locations that may receive higher stormwater runoff volumes. Location and installation details are provided in

Appendix E and F, respectively.

USACOE 3-2 Burns & McDonnell

3.1.3 Inlet Protection

Inlet protection is used to remove sediment from stormwater before it enters storm sewers. Inlet protection is typically constructed of washed gravel, crushed stone, geotextile fabrics, or other materials.

Storm drain inlet protection consists of several different types of inlet filters and traps, depending on the type of inlet. It will be up to the contractor to determine which types of inlet protection are most suitable for the specific type of storm drain inlet. Common types of inlet protection include Gutterbuddies®, Sediment Fence, Block & Gravel, Gravel & Wire Mesh, and Silt Saver®. Other types of inlet protection include rice wattles, rock socks, and coconut logs. It may be necessary to remove inlet protection in freezing weather and/or prior to snowfall. See location and typical implementation details in Appendices

E and F, respectively.

3.1.4 Concrete Washout

A concrete washout area is either a prefabricated unit or a designed measure to contain concrete washout.

These systems are typically used to contain washout water when chutes and hoppers are rinsed following concrete delivery and are implemented to reduce the discharge of pollutants through consolidation of solids and retention of liquids. Uncured concrete and associated liquids are highly alkaline. Without containment measures, these materials could leach into the soil and contaminate groundwater or discharge to a surface waterbody or wetland. If concrete washouts will be utilized onsite, the installation locations must be shown on the ESC Plan located in Appendix E. Installation specifications for concrete washouts are provided Appendix F.

3.2 Permanent Stormwater Management Practices

Permanent stormwater management BMPs are those that are left in place after construction is finished and the site is stabilized to manage stormwater flow, volume, and/or quality. An infiltration basin for stormwater collection has been designed as a permanent stormwater management feature for the Project site.

3.2.1 Check Dams

Check dams are to be installed in existing or construction-related channels/drainages to reduce runoff velocity, filter concentrated flows, and limit the amount of sediment that travels downstream. Check dams are generally used in concentrated flow areas, such as ditches and swales. These barriers must be placed so that the elevation of the outside channel edge is higher than the top of the barrier in the middle of the channel. The proposed check dams will be composed of washed gravel and will be installed as part of the forebay berm to convey water to the infiltration basin. Check dams must be maintained to remain

USACOE 3-3 Burns & McDonnell effective, and sediment must be removed from behind the device on a regular basis. For more information, refer to the locations and design details in Appendices E and F, respectively.

3.2.2 Infiltration Basin

An infiltration basin is designed to hold stormwater runoff and infiltrate the water slowly to avoid downstream flooding and stream erosion. The practice is an extremely effective water quality and peak discharge reduction measure. The infiltration basin will initially be utilized as temporary sediment basin during construction activities. Upon completion of construction activities, the infiltration basin will be cleaned out and converted to a permanent facility. The infiltration basin is designed to treat runoff from a local 2-year, 24-hour storm. Location and installation details for the infiltration basin are provided in

Appendix E and F, respectively.

Stormwater Pollution Prevention Plan Controls - Stabilization Practices

USACOE 4-1 Burns & McDonnell

4.0 CONTROLS - STABILIZATION PRACTICES

The following sections detail the stabilization practices to be implemented during and after Project construction activities.

4.1 Stabilization Practices

Stabilization measures must be initiated immediately whenever earth-disturbing activities have permanently or temporarily ceased on any portion of the Project site and will not resume for a period exceeding 14 calendar days. Temporary and permanent stabilization activities must be completed as soon as practicable, but no later than 14 calendar days after the initiation of stabilization.

As soon as practicable, but no later than 14 calendar days after the initiation of soil stabilization measures, the contractor is required to have completed:

1. For vegetative stabilization, all activities necessary to initially seed or plant the area to be stabilized; and/or

2. For non-vegetative stabilization, the installation or application of all such non-vegetative measures.

4.1.1 Seeding

The contractor or subcontractor is responsible for labor, materials, tools, equipment, and other related items required for preparing ground, sowing seeds, fertilizing, mulching and top dressing, and other soil management practices. It will be the contractor’s or subcontractor’s responsibility to check that the soil seedbed is not blown, washed, or otherwise removed from the site. The contractor or subcontractor must make repairs, including replacement of lost topsoil and mulch, to the seedbed preparation site in the event of heavy rain, wind, or other natural events that cause damage. Seeding and planting practices must adhere to the specifications provided in Appendix F.

4.1.2 Mulching

Mulching must be used in conjunction with seeding practices to enhance the success of vegetation establishment by providing erosion protection prior to the onset of vegetative growth. Mulch must be free of noxious and undesirable seed and other materials and must be crimped into the ground by means of a mechanical spreader or other approved methods. Mulching should be completed within 24 hours following the seeding operation and must be completed in accordance with requirements in Appendix F.

Stormwater Pollution Prevention Plan Controls - Stabilization Practices

USACOE 4-2 Burns & McDonnell

4.1.3 Fertilizer

Disturbed soil may need supplementation from fertilizer, and soil tests may be necessary to determine the most appropriate fertilizer for each location. Once applied, the fertilizer must be worked into the soil to limit exposure to stormwater. Fertilizer spills must be cleaned up immediately, and fertilizer must not be applied along or in a waterway. Fertilizing procedures must adhere to the specifications provided in

Appendix F.

4.2 Final Stabilization

The Project is considered finally stabilized when all soil-disturbing activities have been completed and a uniform (i.e., evenly distributed, without large bare areas) perennial vegetative cover with a density of 70 percent of the native background vegetative cover for the area has been established on all unpaved areas.

For those areas not covered by permanent vegetation control measures, an equivalent permanent stabilization measure (e.g., riprap, gabions, or geotextiles) must be used.

Stormwater Pollution Prevention Plan Other Controls

USACOE 5-1 Burns & McDonnell

5.0 OTHER CONTROLS

The following sections detail other controls to be implemented during Project construction activities to limit the potential for pollutants and sediment to reach the municipal storm sewer system or waters of the

State.

5.1 Dust Control

Preventative measures must be taken during periods of extreme drought or heavy winds when exposed soil is susceptible to wind erosion. In areas where bare soil is exposed, water or other approved and acceptable dust palliatives will be applied to the soil to limit wind erosion. Precautions should be taken not to over-water and erode soils. In addition, appropriate speed limits should be established within the

Project site to limit the generation of dust. Spoil piles should be temporarily stabilized or covered to limit wind erosion.

5.2 Street Sweeping

If sediment is observed leaving the Project site through tracking and is deposited on paved public or private roads, then it must be removed immediately through dry sweeping and not flushing.

5.3 Waste Materials

Solid and liquid waste (including sediment, asphalt, concrete millings, floating debris, paper, plastic, fabric, and construction and demolition debris) must be disposed of in accordance with applicable disposal requirements and regulations. Solid or liquid wastes must not be disposed of onsite (e.g., buried or poured), but must be taken offsite for proper disposal. Waste containers must be inspected regularly, and waste stored onsite must be protected from stormwater exposure. All waste materials, including those associated with the demolition of Building 2426, must be properly disposed of.

5.4 Sanitary Waste

The contractor and subcontractors must comply with applicable portable toilet regulations. Each contractor and subcontractor must provide sanitary facilities for its crews on the Project site for the duration of construction activities. Facilities must not be placed in low-lying areas or near a waterbody and must be positioned so they are secure and cannot be tipped over. Sanitary facilities must be used by construction personnel and must be serviced regularly by a licensed contractor. Once any facilities are brought to site, their locations should be added to the Erosion and Sediment Control Plan in Appendix E.

Stormwater Pollution Prevention Plan Other Controls

USACOE 5-2 Burns & McDonnell

5.5 Hazardous Waste

Hazardous or toxic waste must be separated from construction and domestic waste and must be stored in sealed containers constructed of suitable materials to avoid leakage or corrosion. These containers should be stored within appropriately sized secondary containment. Hazardous waste material must be disposed of in the manner specified by the manufacturer and by local, State, and Federal regulations. These regulations often include testing of materials to identify what hazards may be present and obtaining manifests or receipts to document proper disposal of materials. Spills must be cleaned up immediately and in accordance with protocols outlined in Chapter 7.0. Site personnel must be made aware of these requirements.

In areas where potential hazards are likely to be encountered, such as asbestos during demolition activities or hydrocarbon-contaminated soils near the runway, precautions should be taken to minimize the potential for further contamination prior to commencing ground-disturbing activities.

Stormwater Pollution Prevention Plan Maintenance and Inspection

USACOE 6-1 Burns & McDonnell

6.0 MAINTENANCE AND INSPECTION

Routine maintenance and inspection of BMPs is essential to minimizing erosion and sedimentation on the

Project site and protecting the water quality of receiving streams.

6.1 Inspection Procedures

A qualified person knowledgeable in the principles and practice of erosion and sediment control BMPs and pollution prevention, and who possesses the skills to assess construction site conditions that could impact water quality, is responsible for conducting regular inspections. Table 6-1 will identify personnel responsible for performing inspections prior to the start of construction, and a copy will be kept onsite.

The Project site must be inspected at a minimum, once every 7 calendar days and within 24 hours of the end of a storm event 0.5-inch or greater, or the occurrence of runoff from snowmelt sufficient to cause a discharge. Total rainfall measured for that day must be recorded in accordance with Part 4.7.1d.

Table 6-1: Stormwater Inspector Identification List

Personnel Title Contact Responsibility

6.1.1 Areas Requiring Inspection

The following areas must be routinely inspected:

• Areas that have been cleared, graded, or excavated and have not yet achieved final stabilization

• Stormwater controls, including pollution prevention measures

• Material, waste, borrow, or equipment storage and maintenance areas

• Areas where stormwater typically flows within the site, including drainages designed to divert, convey, and/or treat stormwater

• Points of discharge

• Locations where stabilization measures have been implemented

6.1.2 Inspection Requirements

During site inspections, the inspector must complete the following actions:

USACOE 6-2 Burns & McDonnell

• Verify erosion and sediment controls and pollution prevention controls are installed and operational, and determine if controls require replacement, repair, or maintenance.

• Determine the presence of conditions, if any, that could lead to spills, leaks, or other accumulations of pollutants.

• Identify locations where new or modified stormwater controls are necessary to meet the requirements of Parts 2 and 3 of the Permit.

• Check discharge points and banks of any surface waters flowing within the Project boundaries or adjacent areas for signs of visible erosion and sedimentation that are attributable to site discharge;

if discharge points are not accessible, check nearby downstream locations to the extent practicable.

• Identify incidents of noncompliance.

• If discharge is occurring at the time of an inspection:

o Identify all points of the Project site from which a discharge occurs.

o Observe and document the visual quality of the discharge (color, odor, oils, suspended solids, and other stormwater pollutants).

o Document whether stormwater controls are operating effectively, and note controls that are not operating effectively.

• Inspect locations where vehicles enter or exit the Project site for evidence of offsite sediment tracking along paved roadways.

In areas of the Project site where construction activities have permanently or temporarily ceased and will not resume for a period exceeding 14 calendar days, stabilization measures must be initiated immediately.

The inspection frequency may be reduced to once per month in areas where seeding has been completed, appropriate non-vegetative cover (e.g., hydromulch, erosion control blankets) has been provided, or…
