1. INTRODUCTION

The Rhode Island Department of Environmental Management (RIDEM) has been delegated authority by the United States Environmental Protection Agency (USEPA) to implement the Rhode Island Pollutant Discharge Elimination System (RIPDES) program and issue permits for stormwater discharges to surface water bodies. The Rhode Island Air National Guard (RIANG) 143d Airlift Wing headquarters is located in North Kingstown, Rhode Island. RIANG discharges stormwater associated with industrial activity and is, therefore, subject to the RIPDES program.

RIANG has been operating under RIPDES Permit No. RI0021555 since December 1986. On October 27, 2015, RIDEM renewed individual RIPDES Permit No. RI0021555, and on December 14, 2016, RIDEM modified the permit. The permit authorizes RIANG to discharges stormwater associated with industrial activity via a system of catch basins and underground storm water system through an outfall to Fry’s Pond (water body ID RI0007027L-06) approximately ½ mile northwest of the facility. The current permit will expire on December 31, 2020. A copy of the permit and modification are provided in Appendix A.

This Stormwater Pollution Prevention Plan (SWPPP) has been prepared in accordance with the requirements of the RIPDES Permit. The purpose of the SWPPP is to identify potential sources of pollution that may affect the quality of industrial stormwater discharges from RIANG, describe and ensure implementation of Best Management Practices (BMPs) to reduce pollutants in industrial stormwater discharges, and ensure compliance with the RIPDES Permit.

2. FACILITY INFORMATION

2.1 FACILITY DESCRIPTION

RIANG’s mission is to deliver passengers and cargo by airdrop, extraction, and air/land support of theater commands throughout the world using C-130J aircrafts. The major support operations performed at Quonset include aircraft refueling, aircraft maintenance, aircraft deicing, aerospace ground equipment (AGE) maintenance, ground vehicle maintenance, refueling of ground vehicles, and facilities maintenance.

RIANG is located at the Quonset State Airport in North Kingstown, Rhode Island (Washington County), approximately 1,200 feet west of the Narragansett Bay at its closest point. Narragansett Bay surrounds Quonset Point on three sides.

RIANG is a tenant of the land owned by State of Rhode Island and is responsible only for the operation and maintenance of the approximately 94-acre tract on the western side of the Quonset State Airport property. Properties surrounding RIANG include airport taxiways and runways to the east, a public golf course to the north, Toray Plastics (America), Inc. (an industrial plastic film manufacturer) to the west, and light industrial facilities to the south. Other nearby industries that could contribute to stormwater conditions at RIANG include; General Dynamics (Electric Boat), Suburban Propane, Quonset Development Corporation, Rhody Transportation, and Fuji Film Electric Materials.

Figures 1A and 1B provide site location and topography maps and Figures 2 and 3 provide site maps for RIANG, including the facility layout, direction of stormwater flow, potential pollutant sources, stormwater discharge areas, and outfalls.

4. STORMWATER AND NON-STORMWATER DISCHARGES

4.1 STORMWATER DISCHARGES

RIANG consists of about 94 acres, approximately 33 acres of which is pervious (grassy/vegetated), and approximately 61 acres of which is impervious (pavement/rooftops). The runoff coefficient is 0.51.2

Flow is primarily overland to surface drainage ditches and storm drain inlets connected by a network of underground pipes that comingle with runoff from the Quonset industrial complex3 and exit the property through a 60-inch pipe at the northern boundary (adjacent to a municipal golf course). The receiving water is Fry’s Pond, which ultimately discharges to Narragansett Bay via an underground pipe.

RIANG uses multiple control systems, as described as follows:

• Oil/petroleum controls:

o Building-specific oil water separators (OWSs) are located in Building 3, Building 11, Building 14, Building 571, and Building 575. These smaller-capacity units are designed to control industrial wastewater discharges from the associated buildings and are not intended to treat large volumes of stormwater.

o Two grease traps are used in the kitchen.

o A 10,650-gallon OWS with a 6,000-gallon oil capacity is located at the POL refueler parking area (Facility ID# 18). Due to its proximity to the main petroleum storage area, this unit is the first line of defense in the event of a major spill.

o A 25,000-gallon OWS is located near the runway proximal to where stormwater discharges to Fry’s Pond. This unit serves as a backup in the event of a release that overwhelms the 10,650-gal OWS.

• Deicing pad controls:

o A diversion structure allows RIANG to switch between normal/standby mode to deicing mode by pushing one button. The key features of this system includes:

Standby mode (no alarms or lights) – Effluent gravity drains to the stormwater system;

Deicing mode (amber strobe light and audible alarm) – Effluent gravity drains to a pump chamber, which fills until a float switch is activated and sends effluent via force main to a 25,000-gallon glycol recovery system, i.e., underground storage tank (UST);

90% capacity indicator (red strobe light and lockout system);

Tank filling indicator (green strobe light); and

Spill control (“all closed”) button – Activates alarms and closes both valves to trap spilled fuel in the manhole/piping upstream of the diversion structure.

Figures 2 and 3 depict the stormwater drainage system. The following Table 4-1 summarizes the former and current drainage areas and outfalls.

2 The drainage area of the base and acreage calculations for pervious and impervious areas were based on the prior SWPPP.

3 Discharges from the neighboring industrial complex (Three locations along Cripe Street, another from Conway Avenue, one from the golf course, etc.) pass through the Base’s conveyance system and discharge into Frys Pond.

(DMH-27)

D-002 is approximately 33,000 square feet (0.758 acres) and 100% impervious. Although substantially smaller than the footprint of RIANG, it allows RIANG to monitor stormwater generated exclusively on base before it co-mingles with flow from the rest of the industrial complex.

Stormwater from drainage area D-002 is collected by catch basins within the POL yard and passes through a 10,650-gallon oil/water separator. After discharging from the O/W separator, stormwater drops into Outfall 100 A/B located inside the POL-secured area before co-mingling with existing stormwater flow on its way to Fry’s Pond.

Outfall 100A is an 8-inch diameter discharge line from the O/W separator in the POL yard into DMH-27. This is the wet weather sampling designation.

(DMH-27)

Outfall 100B is at the same location as Outfall100A, but separately designated to clarify it is the dry weather sampling location (for release of rainwater from the dykes around Tanks 110 and 111).

Secondary containment areas that may collect stormwater are controlled by manually-activated valves that remain closed at all times except when making a controlled release. Accumulated stormwater will be inspected prior to discharge as described in Section 7.

4.2 ALLOWABLE/”APPROVED” NON-STORMWATER DISCHARGES

4.2.1 AIRCRAFT CLEAR WATER RINSE (CWR) REQUIREMENTS

Aircraft stationed within 1.25 miles (2 km) of salt water typically require a CWR at least once every 15 days for corrosion control unless washed first. Aircraft that fly below 3,000 feet over salt water making two or more take off and landings, including touch and go’s, also require the 15-day rinse frequency. Currently, RIANG rinses on a 30-day cycle and only when the weather is consistently below 40 °F. The procedure is accomplished while the aircraft are parked on the parking ramp. The current CWR procedure calls for the use of fire department truck hoses set at a soft spray pattern to ensure a sufficient flow of fresh water over the surface of the aircraft. The rinse utilizes approximately 200 to 500 gallons of water per aircraft depending on the spray pattern and water pressure from the fire truck. Aircraft CWR procedures typically last no more than 5-10 minutes.

4 The former outfall was not exclusive to RIANG’s effluent, was tidally-influenced, and was nearly 100% underwater for two-thirds of the day, resulting in compliance samples being comprised mostly of water from Narragansett Bay. Although the designated drainage area is substantially smaller than the overall footprint of the property, it was chosen because it is the only area that generates stormwater runoff solely attributed to RIANG’s activities. (The remainder of the stormwater conveyance system receives a mixture of stormwater that originates from RIANG or enters RIANG-leased property via cross-connections along the southern edge of the base under Cripe Street).

RIANG (0231119.02) 4-3 Woodard & Curran

4.2.2. C-130J ENGINE COMPRESSOR WASHES

Engine-flush compressor washes may be conducted every 15 days at RIANG due to the proximity to salt water/salty air; however, currently, RIANG washes on a 90-day cycle. Washes will be conducted whenever an engine air inlet/compressor shows salt deposits from ingested salt water or mist during flight, unless inspections indicate a more frequent requirement or inspection indicates the need does not exist. Engine compressor washes are done outside on the deicing pad (Pad 7) because engines have to be motored to properly complete a wash. The procedure entails inputting a water/soap mix into the engine (after fuel has been drained) using a gas turbine air compressor; then, the engine is started in order for the mix to be drawn through the cylinders. The procedure does not mobilize residual aviation fuel or oil associated with the aircraft engine. The spray/mist is ejected into the air and dispersed; then fresh water is input into the engine for flushing until the exhaust is clear.

Note: During an inspection on Sept. 24, 2014, RIDEM staff witnessed and approved both the CWR and C-130 engine compressor wash procedures. In general, vehicle and aircraft washes, including engine compressor washes, are not authorized by RIDEM as allowable discharges under stormwater permits. At RIANG, engine compressor wash water is captured and contained on the pad or in the glycol recovery tank, never entering the stormwater system (i.e., not discharged). Thus, it is an approved process, but not an authorized discharge.

Non-stormwater discharges authorized under RIPDES permit Part A.15 are identified in the following table.

Appendix B provides RIANG’s evaluation for non-stormwater discharges other than allowable non-stormwater discharges.

4.3 WASTEWATER DISCHARGES

Floor drains in all buildings presently discharge to the Quonset Development Corporation (QDC) sewer system according to terms set forth in their wastewater permits. Unless specifically approved by QDC, floor drains must be capped and/or plugged at all times and cannot discharge industrial wastewater (sanitary wastewater only).

4.4 OTHER (NON-PERMITTED) DISCHARGES

Sources of non-stormwater other than those listed in Table 4-2, such as wash water from steam cleaning, vehicle and equipment wash water, parts washers, and other equipment cleaning operations are not authorized by the RIPDES permit and cannot enter the stormwater conveyance system.

4.4.1 AIRCRAFT WASHING/DEICING ON APRON

United States Air Force (USAF) Technical Order (TO) 1-1-691 and USAF TO 1-1-689 require aircraft housed outside in close proximity to the ocean be washed in either a 30-day to 90-day rotation (based on mission) as a corrosion control preventative measure. The base is adjacent to Narragansett Bay; planes are parked outside on the ramp year round (when not deployed) as there are only two hangars where aircraft can be covered during maintenance activities.

Under the current stormwater permit, the effluent from an aircraft wash, with soap, is prohibited from discharge to the stormwater conveyance system due to the potential that the wash water effluent might contain oils, grease, soap, heavy metals (specifically cadmium) and other contaminates not allowed in the stormwater discharge. The amount of water required for a wash varies based on the condition of the aircraft but can range between 3,000-6,000 gallons per wash.

During the recently completed renovation of the Fuel Cell Hangar (Building 8), a closed loop, water recycling system was installed to provide for indoor washing of aircraft by maintenance personnel. Indoor washing is the default method

RIANG (0231119.02) 4-5 Woodard & Curran for washing aircraft, which uses a soap/water mix that circulates through in-line filtration tanks. Wash water from indoor plane washes is captured, treated, recycled and not discharged to either the stormwater or wastewater system.

There are certain instances when aircraft must be washed outside on the deicing pad; however, there is no resulting impact to the stormwater system. The plane wash water mix from outdoor washes is captured/discharged into the 25,000-gallon glycol recovery tank. QDC may authorize batch discharges of plane wash water which is contained in the 25,000-gallon UST provided that laboratory analytical testing results meet their wastewater permit limits and approval is granted. If waste characterization reveals that hazardous constituents are present in the wash water, then a licensed waste hauler is used to transport it to a licensed treatment facility.

Note: During an inspection on Sept. 24, 2014, RIDEM staff witnessed and approved outdoor aircraft washing for mission-essential aircraft during non-winter months.

With respect to de-ice operations, RIANG has specific training missions that require formation flying. In the case where two or more aircraft are required to become airborne in close succession, one aircraft will be deiced on the deicing pad and the remaining aircraft will be deiced in their current parking positions on the pads. The deicing trucks will circle the aircraft using a 50/50 (or appropriate ratio) application mixture of heated water and deicing fluid, minimizing usage and environmental impact. Maintenance personnel will log all use of deicing fluid that includes dates, times, and amounts and whether the fluid was applied on or off the collection pad. In the event the fluid needed to be applied off the pad, the reason for such shall be noted in the log and communicated to the RIANG Environmental Management Office (EMO). Deicing fluid is recycled unless the mixture is known to contain non-glycol constituents. In the latter case, the water is tested and transported for recycling and/or proper disposal off site by a licensed contractor.

Occasionally, transient military aircraft will land at the RIANG and require de-icing. If an aircraft is too large for RIANG’s deicing pad, it can be serviced on Quonset State Airport property, with permission. If feasible, the RIANG will make attempts to recover deicing fluid and transfer the recovered fluid to the 25,000-gallon glycol holding tank.

RIANG submits annual stormwater reports to RIDEM covering stormwater management and de-icing as required by permit. A complete deicing Standard Operating Procedure (SOP) is located in Appendix D.

5. POTENTIAL POLLUTANT SOURCES AND BEST MANAGEMENT PRACTICES

(BMPS)

Potential pollutant sources are present as a result of the activities performed at RIANG. BMPs have been implemented as appropriate. In selecting BMPs for each source, the types of pollutants and the potential for exposure were assessed, considering the factors described in the RIPDES permit.

Most of RIANG’s exposed industrial activities occurs at the deicing pad/apron, in the vicinity of Buildings 3, 571 and 575, and in the POL yard (bordered by Building 14 to the east, Hercules Drive to the south, Building 3 to the west, and Wingman Way to the North.

Table 5-1 lists RIANG’s facilities and indicates whether each area has industrial activities that are potentially exposed to stormwater. Unless noted, activities that do not have potential exposure to stormwater (indicated by “None” in the following table) are not addressed in this SWPPP.

RIANG (0231119.02) 5-4 Woodard & Curran

Table 5-2 describes each pollutant source that may potentially be exposed to stormwater, typical exposed quantities, risk level, and BMPs. Figure 2 shows the facilities where potential pollutant sources are located. Allowable non-stormwater discharges and associated BMPs were described in Section 4.2.

In addition to the activities described in Table 5-2, the following general control measures are in place at RIANG.

• Good Housekeeping – A clean, orderly facility will be maintained. See Section 6 for details.

• Minimizing Exposure – Due to the nature of activities at RIANG, some of the industrial activity will be performed in outdoor areas. Where practicable, industrial materials and activities at RIANG will be protected by a storm-resistant shelter or covering to prevent exposure to precipitation. See Table 5-2 for details.

• Preventive Maintenance – Equipment and systems will be inspected and tested as necessary to identify conditions that could cause breakdowns or failures resulting in the discharge of pollutants to surface waters. See Section 6 details.

• Spill Prevention and Response Procedures – RIANG maintains a Spill Prevention and Response Plan (SPRP) to facilitate quick response to emergencies. See Section 10 for details.

• Routine Facility Inspections – Qualified personnel will inspect designated areas of the facility and equipment at appropriate intervals. See Section 7 for details.

• Employee Training – Employee training will be provided to inform personnel, at all levels of responsibility related to the components and the goals of this SWPPP. See Section 9 for details.

• Sediment and Erosion Control – The facility is relatively flat and is not expected to have a high potential for soil erosion due to topography, local activities, and ground surfaces that will be generally covered with pavement or crushed concrete/stone. Disturbance during construction and renovation will meet the requirements of the RIDEM Stormwater Construction Activities regulations.

• Management of Runoff – RIANG’s structural stormwater controls include two stormwater OWSs. Additionally, runoff from deicing operations will be managed using a glycol recovery system to reduce the amount of pollutants discharged from the site. See Section 7 for inspection details and Appendix D for deicing standard operating procedures.

The BMPs identified in Table 5-2 will be maintained in effective operating condition. If RIANG determines that BMPs are not being properly operated or maintained, corrective actions will be initiated and documented.

5.1 FUTURE/PLANNED CONTROL MEASURES

5.1.2 AIR FORCE SERVICE STATION (AFSS)6

RIANG has proposed improvements to the AFSS, i.e., Government Vehicle Refueling Area, which requires design funding. Once a design is approved, the Defense Logistics Agency (DLA) will provide funding. In accordance with the RIPDES permit and September 2016 RIANG Refueling Area Improvement Plan, RIDEM must review and approve any plan, which will consider the following stormwater controls:

• Treat stormwater from the fuel dispensing and tank filling areas using a multi-chamber OWS or acceptable proprietary device (minim oil storage capacity of 500 gallons) that is preceded by at least one catch basin;

6 The US Army Corps may initiate design in 2019, pending sign off from the US Property and Fiscal Office. RIANG will prepare a change order for a trench to capture snow melt during renovation of the Vehicle Maintenance building.

RIANG (0231119.02) 5-5 Woodard & Curran

• Provide a roof over the fuel dispensing areas to prevent stormwater from running in/through them;

• Elevate the fuel dispensing and tank filling areas to prevent stormwater from running in/through them; and

• Provide grooved concrete for the perimeter of the pad around the fuel dispensing area to be used to contain all spills.

5.1.3 POL FUELS COMPLEX MODERNIZATION

RIANG provided RIDEM with digital design plans in January, 2019 when the design was 35% complete. The design is expected to be finished in June 2019 with 100% design by September 2019. The US Army Corps is managing the design and must consider the RI Stormwater Design Manual.

5.2 SPILLS AND LEAKS

In the last three years, RIANG has not experienced a significant spill event but has experienced small reportable spills.

All recorded spills have been contained onsite and cleaned up within 24 hours of the release. Written reports were submitted to RIDEM, as required. Spill reports are maintained at the Environmental Management Office. These records include the date, cause, description, and location of the spill; spill amount and material information; response actions taken; and potential environmental impacts.

6. HOUSEKEEPING AND PREVENTATIVE MAINTENANCE

Good housekeeping and regular equipment maintenance are effective and inexpensive methods of pollution prevention when used in conjunction with regular inspections. RIANG will utilize housekeeping practices to keep exposed areas free of waste, garbage, and floatable debris. RIANG also implements routine preventative maintenance for industrial equipment to help avoid situations that may result in leaks, spills, or other releases. Preventative maintenance procedures and schedules recommended by the equipment manufacturers will be implemented as appropriate for equipment present onsite. Key components of RIANG’s preventative maintenance and housekeeping practices relative to stormwater pollution prevention and compliance are outlined below:

• Dumpsters and recycle bins will be covered to prevent rainfall from contacting contents, located on impervious surfaces, maintained in good condition, and emptied as necessary. As needed, the area around dumpsters will be swept to prevent trash/waste materials from washing into the storm drainage system.

• The facility, including catch basins and other inlets to the stormwater drainage system, will be routinely inspected as described…
