SECTION 1

1. Introduction

1.1 Overview and Purpose

Tyndall Air Force Base (AFB) is located in Bay County, Florida, southeast of Panama City. It occupies approximately 28,000 acres on a narrow 16-mile long peninsula bordered by St.

Andrew Bay and East Bay to the north, and the Gulf of Mexico and St. Andrew Sound to the west. This location is shown graphically in Figure A-1 of Appendix A. The topography of Tyndall AFB is relatively flat with a rise to a maximum of approximately 30 feet above sea level (asl).

The purpose of this Stormwater Pollution Prevention Plan (SWPPP) is to assist Tyndall AFB in complying with their stormwater permit. The primary aim of this document is to serve as a guide for the base personnel who are responsible for ensuring that there is minimal stormwater pollution as a result of industrial activities on the base. This document also refers to stormwater management practices that the personnel at the base should follow for minimal exposure of contaminants to the stormwater.

The process of developing a SWPPP includes the following four steps:

1. Formation of a team of qualified personnel who will be responsible for preparing the plan and assisting the Stormwater Team Leader in its implementation.

2. Assessment of potential stormwater pollution sources.

3. Selection and implementation of appropriate practices and controls.

4. Periodic evaluation of the effectiveness of the plan to prevent stormwater contamination and comply with the terms and conditions of this permit.

Tyndall AFB is currently operating under the Multi-Sector Generic Permit (MSGP) (Facility ID: FLR05C304) issued by the Florida Department of Environmental Protection (FDEP) on June 19, 2006. The MSGP was issued under the provisions of Section 403.0885, Florida Statutes, and applicable rules of the Florida Administrative Code (F.A.C.). This plan has been developed in accordance with the MSGP permit.

Tyndall AFB is permitted under the Industrial Sector “S,” Air Transportation Facilities, of the National Pollutant Discharge Elimination System (NPDES) to operate facilities and discharge stormwater to surface waters. A copy of the MSGP permit is provided in Appendix B. The updated Tyndall AFB SWPPP is prepared in compliance with the Florida MSGP. It documents stormwater management practices at the base and will serve as a guide for the base personnel who are responsible for ensuring that the potential for stormwater contamination is minimized.

1.2 Regulatory Overview

In 1972, the Federal Water Pollution Control Act, also referred to as the Clean Water Act (CWA), was amended to provide that the discharge of pollutants to waters of the United States from any point source is effectively prohibited, unless the discharge is in compliance with the NPDES permit. In October 2000, the U.S. Environmental Protection Agency (EPA) authorized the FDEP to implement the NPDES stormwater permitting program in the State of Florida (in all areas except Indian Country lands). FDEP’s authority to administer the NPDES program is set forth in Section 403.0885, Florida Statutes (F.S.). The NPDES stormwater program regulates point source discharges of stormwater into surface waters of the State of Florida from certain municipal, industrial, and construction activities. As the NPDES stormwater permitting authority, FDEP is responsible for promulgating rules and issuing permits, managing and reviewing permit applications, and performing compliance and enforcement activities.

The NPDES stormwater permitting program is separate from the State of Florida’s stormwater/environmental resource permitting programs (found under Part IV, Chapter 373, F.S. and Chapter 62-25, F.A.C. and local stormwater/water quality programs, which have their own regulations and permitting requirements.

The sources of stormwater discharges regulated under the NPDES program fall into three categories. Follow the links below for more information on each:

• Industrial Activity http://www.dep.state.fl.us/water/stormwater/npdes/industrial1.htm

• Construction Activity http://www.dep.state.fl.us/water/stormwater/npdes/construction1.htm

• Municipal Separate Storm Sewer Systems http://www.dep.state.fl.us/water/stormwater/npdes/MS4_1.htm

This SWPPP is developed for compliance with the above Industrial Activity category for the NPDES program and does not address Construction Activity, Municipal Separate Storm Sewers (MS4s), or the State of Florida Stormwater Permitting found in Chapter 62-25, F.A.C.

Though EPA has modified the NPDES MSGP for Industrial Activities, the State of Florida is authorized to implement and has adopted the 1995 MSGP (Vol. 65 FR No. 83, p. 25123). The MSGP regulations require that a facility obtain permit coverage if there is stormwater discharge associated with industrial activity and the discharge is either directly to surface waters or indirectly through MS4s. The Federal Register (FR), Volume 60 No. 189, defines the industrial activities covered by the MSGP. The State of Florida MSGP for Stormwater Discharge Associated with Industrial Activity divides the regulated industrial activities into 30 sectors of related activity and specifies both general and sector-specific requirements for each. The permit, developed by EPA and then adopted and renamed by FDEP in October 2000, consists of the original 1995 issuance and the subsequent modifications and corrections.

The following is a list of base activities which were analyzed to determine if they should be permitted under any of the Sectors of the MSGP.

• Timber Product Facilities (Sector A)

• Hazardous Waste Treatment, Storage, or Disposal Facilities (Sector K)

• Scrap Recycling and Waste Recycling Facilities (Sector N)

• Ship and Boat Building or Repairing Yards (Sector Q)

• Air Transportation Facilities (Sector S)

1.2.1 Sector A: Timber Product Facilities

Tyndall AFB conducts several non-point source silvicultural activities such as timber harvesting operations, site preparation, road construction, and controlled burns. In accordance with 40 Code of Federal Regulations (CFR) 122.27(b), point sources that must be covered by an NPDES permit are “any discernible, confined and discrete conveyance related to rock crushing, gravel washing, log sorting, or log storage facilities, which are operated in connection with silvicultural activities and from which pollutants are discharged directly into waters of the United States.” Discharges from non-point source silvicultural activities are not required to be covered. Therefore, these activities are not covered in this SWPPP.

1.2.2 Sector K: Hazardous Waste Treatment, Storage, or Disposal Facility Tyndall AFB generates hazardous waste during many of its operations. However, Tyndall does not meet the definition of a treatment, storage, or disposal facility (TSDF) in 40 CFR 264 because the waste is sent offsite to a TSDF within 90 days of collection. Because Tyndall does not meet the definition of a TSDF under this sector, this sector’s requirements are not addressed as part of this SWPPP. However, Tyndall accumulates its generated hazardous waste in a manner to prevent contact between stormwater and the waste. These BMPs are listed in Tyndall’s Hazardous Waste Management Plan, found in the CEV office.

1.2.3 Sector N: Scrap Recycling and Waste Recycling Facilities Tyndall is operating a Recycling Facility; however, the stormwater discharge for this site is to an open field and not to any State or U.S. waters, and not to an MS4. This was clarified to FDEP on December 16, 2002, and the documentation is presented in Appendix C. Due to this discharge situation, Sector N requirements are not included in the SWPPP.

1.2.4 Sector Q: Ship and Boat Building or Repairing Yards

Tyndall has two marinas, Bonita Bay and Beacon Beach. These marinas will be treated with a separate permit and SWPPP if needed and will not be addressed herein.

1.2.5 Sector S: Air Transportation Facilities

Tyndall meets the definition of this sector and obtained permit coverage under this sector in June 19, 2006. This SWPPP is developed as per the requirements of Sector S of the MSGP.

1.3 SWPPP Organization

This SWPPP is organized as follows:

Section 1 – Introduction briefly describes Tyndall AFB and the regulatory background.

SECTION 2

2. Stormwater Pollution Prevention Team

2.1 Introduction

The two major objectives of the MSGP are (1) to identify sources of pollution potentially affecting the quality of stormwater discharges associated with industrial activity from a facility and (2) to describe and ensure implementation of practices to minimize and control pollutants in stormwater discharges associated with industrial activity for the facility, and to ensure compliance with the terms and conditions of this permit. The SWPPP helps facilitate a process for the operator of the industrial facility to thoroughly evaluate potential pollution sources at the site and select and implement appropriate measures designed to prevent or control the discharge of pollutants in stormwater runoff (FR, vol. 60 no. 189, p.50814). In order to reach these objectives, the SWPPT has been formed by a team of qualified base personnel to perform the following:

• Implement and maintain the SWPPP in accordance with good engineering and management practices.

• Identify and incorporate into the plan any potential sources of pollution that could reasonably be expected to impact the quality of stormwater on base.

• Develop, document, and implement improved management practices to reduce the potential for contamination of stormwater discharges.

• Complete the annual Comprehensive Site Compliance Evaluation (CSCE) and submit the results of this evaluation for the time period specified by the permit conditions.

• Review the SWPPP annually and revise as necessary.

2.2 Team Members and Responsibilities

The following paragraphs provide the specific responsibilities of each team member.

2.2.1 Team Leader, Program Manager for Stormwater Management

The Team Leader bears overall responsibility for the implementation of the SWPPP and will delegate responsibilities to other team members as appropriate. The Team Leader’s main responsibilities include:

3. Drainage Characteristics and Outfall Descriptions

WPB310127161417.DOC/063530015 FINAL TYNDALL AFB

THIS IS AN UNCONTROLLED DOCUMENT IF PRINTED AND AS SUCH SHOULD BE REGARDED AS A REFERENCE ONLY

3.1 Base Characteristics

Tyndall AFB has an extensive stormwater piping network. Stormwater from the industrial areas of the base and the property that surrounds the runway is channeled to one of the seven outfall locations via the storm drain network.

The stormwater collection system serves a variety of facilities on the base, a number of which are classified as industrial activities covered under the NPDES regulations for stormwater permitting. These include aircraft hangars, aircraft parking ramps, runways, fuels dispensing and storage, washracks, maintenance shops, warehouses, and wastewater treatment facilities. The work performed indoors does not pose a meaningful threat to the stormwater system. Maintenance activities performed on the aircraft parking ramps rarely pose a threat to the stormwater system; minor leaks are controlled by the use of sorbent pads and other preventive measures. A complete layout of the storm drain system of the industrial side of the base is shown in Figure A-1 of Appendix A.

3.2 Receiving Waters

Outfalls A, B, E, and F discharge into Shoal Point Bayou, which is located to the northwest of the base. It is the major receiving water to the north of Tyndall AFB. Outfall C discharges into Little Cedar Bayou, which is located northeast of the base. Outfall D discharges into St.

Andrew Sound located to the south of the base. Outfall G discharges into East Bay located to the northeast of the base.

3.3 Drainage Areas and Outfall Description

As mentioned above, the industrial areas at the base drain through one of the seven stormwater outfalls. These outfalls are designated as Outfalls A through G. Appendix D includes the photos for all seven outfalls. Detailed descriptions of the outfalls and the respective drainage areas are provided in the following sub-sections. Figures depicting Outfalls A through G are provided in Appendix A.

3.3.1 Outfall A

Outfall A encompasses the northwest area of the runway on the flightline side of Tyndall AFB. The area of the outfall is approximately 200 acres. The impervious fraction of this area is approximately 73 acres (47 percent).

A system of pipes, catch basins, drain inlets, manholes, and related construction is in place to drain stormwater from this outfall area. Two separate collection systems combine to form a tributary to Shoal Point Bayou. The discharge location for Outfall A consists of four rectangular conduits (approximately 48 inches tall and 36 inches wide) that are used to bridge the drainage channel. The drainage channel is approximately 12 feet wide where the two streams come together.

There are no Installation Restoration Program (IRP) sites in this outfall; however, several IRP sites are located downstream in the channel near Shoal Point Bayou. More than 30 buildings are located within this outfall area and several contain industrial activity. The buildings include two hangars, Base Operations, Avionic Maintenance Shops, and Armament Release Systems Maintenance Shops.

Significant materials handled in this outfall area include:

• (Jet fuel) JP-8, MOGAS

• Oil, diesel fuel

• Hydraulic fluids, antifreeze

• Solvents, paints

• Degreasers, detergents

• Hazardous waste

• Aqueous Film Forming Foam (AFFF) agents

The most significant material handled involves fuel transfer activities. Over 4 million gallons of jet fuel are consumed at Tyndall AFB on a monthly basis. At present, fuel is received by barge at Shoal Point Bayou and transferred to the Fuels Management Division storage tanks where it is loaded onto R-11 fuel trucks, which then refuel aircraft on the flightline. The apron area in front of Hangar 1 (Building 180) and Hangar 2 (Building 182) is where the majority of fueling activity takes place in Outfall A.

Hangars 1 and 2 are engaged in the repair and maintenance of aircraft. The repair activities in the hangars generate small quantities of lubricating oils, hydraulic fluids and fuels which pose a small risk to the stormwater system. Waste fluids are segregated and collected for recycling or proper disposal. Minor aircraft maintenance occurs on the aircraft parking ramps. When minor spills (i.e., spills that don’t require implementation of the spill plan) do occur, they are cleaned up using sorbent materials and disposed of as hazardous waste. A hazardous materials storage shed and a hazardous waste accumulation point is adjacent to Hangar 2. These sheds store materials used by personnel or spent materials previously used and ready for discarding. Both sheds are fully enclosed and provide adequate storm-resistant shelter. The Base Fuels Management Group parks R-11 fuel trucks in front of Building 117.

Several other buildings in the Outfall A area are engaged in industrial-type activities in direct support of flightline operations. These buildings include the Avionics Shop (Building

186) and the Armament Release Systems Shop (Building 188) which operate small-scale painting and hydraulic operations, and the Base Civil Engineers Shops (Buildings 421, 425 and 427). All generate waste materials that are stored indoors and would not pose a threat to the stormwater system.

The drainage area for Outfall A is shown in Figure A-2 in Appendix A. The exhibits that follow show the current outfall condition.

EXHIBIT 3-1

EXHIBIT 3-2

Outfall A Canal, Adjacent to Florida Avenue

3.3.2 Outfall B

Outfall B drains an area of approximately 360 acres along the west central portion of the runway. Approximately 34 percent (92 acres) of the Outfall B are is impervious. There are three separate networks of piping, drains, catch basins, and drop inlets in place that discharge stormwater from Outfall B to Shoal Point Bayou. All three networks combine to form an unnamed tributary of Shoal Point Bayou. Two of the drainage systems are relatively small and serve only small portions of the runway. The third drainage system serves all of the developed portions of Outfall B and the apron portion of the runway in the Outfall B area. The discharge location for Outfall Area B is a channel located on the north-central side of the runway. The channel is approximately 25 feet wide.

Industrial activity in the Outfall B area includes the apron area where aircraft are refueled on the south side of the runway. Other industrial sites include Buildings 83 and 168, which are aircraft washracks using biodegradable cleaning solutions. Buildings 166 and 169 house washrack equipment and supplies. All effluents from the washracks are directed to OWSs and eventually to the Bay County Wastewater Treatment Plan (WWTP).

Hangar 3 (Building 156) is engaged in activities that are related to the maintenance of aircraft shells and surface coating operations. The hangar houses a fabrication shop which operates a small walk-in paint booth with a particulate air filter to control air emissions.

Another area of significant industrial activity is the Vehicle Maintenance Area that includes Buildings 558, 559, 560, 561, 571, and 575. These buildings comprise the majority of non-aircraft vehicle maintenance activities carried out at Tyndall AFB. Building 558 is a washrack behind the tire shop (Building 571) facing Alabama Avenue. All repair activities are completed indoors and are not exposed to precipitation. Small quantities of hazardous waste are generated in these buildings including cleaning solvents, antifreeze, lubricating oils, lead-acid batteries, and waste paint/thinners. All wastes are segregated and disposed of as hazardous waste.

Building 522 is the location of the defense support services contractor, which houses a welding shop, machine shop, corrosion control shop, accessories branch for servicing batteries, and a hydraulic repair shop. Only the accessories shop and hydraulic repair shop generate hazardous waste, the majority of which is either recycled or disposed of as hazardous waste. The drainage area for Outfall B is shown in Figure A-3 of Appendix A.

The exhibit below depicts the current outfall condition.

3.3.3 Outfall C

Outfall C contains the largest outfall area at Tyndall AFB, encompassing approximately 760 acres. The area of the outfall is non-contiguous, but has been grouped in a manner consistent with the final destination of stormwater drainage. From a surficial view, Outfall D basically splits Outfall C in half. Approximately 264 acres (40 percent) of the Outfall C area is impervious to precipitation. Outfall C contains three stormwater drainage systems that discharge to Little Cedar Bayou. Two of the drainage systems are small and drain small portions of the runway. The third drainage system serves the apron portion of the runway and the buildings in the outfall area. This drainage system generates the majority of stormwater flow to the outfall. The discharge location for Outfall C is a channel located on the northeastern side of the runway.

There is one IRP site located in the Outfall C area. FT023 is adjacent to the active fire training area that is used to simulate aircraft and fuel spill fires. The area is currently being remediated to correct soil and groundwater contaminated with petroleum hydrocarbons.

Building 21 also is part of this site.

As with Outfalls A and B, the primary industrial activity in Outfall C is the aircraft fueling operation that occurs on the apron of the runway, and maintenance hangar operations. Hangar 4 (Building 280) is operated by the 95th Aircraft Maintenance Unit and performs structural and mechanical maintenance on aircraft. Hangar 5 straddles the borderline between Outfalls C and D; half of Hangar 5 is used by Lockheed, an onsite contractor for aircraft maintenance. The activities and wastes generated in Hangars 4 and 5 are similar to those generated in Hangars 1, 2, and 3 and consist primarily of fuels, lubricants, and painting wastes.

Other significant industrial activities that occur in Outfall C consist largely of storage activities that occur in the following buildings:

• Building 266 - General storage including adhesives, paints

• Building 267 - Hazardous materials storage

• Building 269 - Hazardous materials storage

• Building 272 - Acid storage

• Building 317 - Paint storage

• Building 319 - Paint storage

• Building 322 - Hazardous materials storage

All of these buildings are relatively small (4,000 square feet [ft2] or less), with the exception of Building 266 (30,000 ft2). There are no materials stored outdoors in the vicinity of the buildings.

Building 315 is a corrosion control facility that operates a solvent distillation unit for reclaiming polyurethane-based paints and used solvents for reuse as a cleaning solvent on equipment items and parts. The building also serves as a hazardous waste accumulation point for paint stripping, unusable solvents, paint booth filters containing metals, lubricants and still bottoms from the solvent distillation unit.

Building 316 is the fuel systems building and drains jet fuels from tank cells. The majority of the fuel is collected and reused. Small amounts of fuel can be found in the water used during cleanup operations. The water passes through and oil/water separator prior to being released to the sanitary wastewater system. Foam baffles from the tanks are removed and disposed of as hazardous waste.

In addition, there is one cooling tower (Building 546) in the Outfall C area. The blow-down from this cooling tower discharges to the sanitary sewer system and is not considered a potential stormwater pollutant source.

The drainage area for Outfall C is shown in Figure A-4 of Appendix A. The following photos show the current conditions of the outfall.

3.3.4 Outfall D

Outfall D has a total area of approximately 35 acres and a total impervious area of about 23 acres (65 percent). This outfall area is bracketed to the east and west by Outfall C with the active flightline to the north and U.S. Highway 98 to the south. Outfall D discharges from a headwall located just south of Highway 98, near the radar test squadron and flows into an unnamed tributary of St. Andrew Sound.

Only two industrial activities are present in this area, Hangar 5 (Building 227) and Building

224. Hangar 5 straddles the border between Outfall Areas D and the eastern half of Outfall Area C. The southern portion of Hangar 5 discharges to stormwater inlets that channel runoff to Outfall D. A portion of Building 224 is used to service temporary duty (TDY) aircraft, not typically assigned to Tyndall AFB.

The activity in Building 310 (Non-Destructive Inspection [NDI] lab) is not considered industrial activity under the current stormwater regulations since this portion of the facility is not involved in vehicle maintenance or other categories defined under NPDES regulations. Several small amounts of hazardous materials are consumed in Building 310 including acid, solvents, fluorescent dyes, and photographic wastes. Since 90 percent of the photographic activities are digital file processing in nature, these old-technology photographic wastes are not considered threatening to the stormwater system. There is no outdoor storage of material at Building 310.

The drainage area for Outfall D is shown in Figure A-5 of Appendix A. The photos below show current outfall conditions at the mouth of St. Andrew Sound.

3.3.5 Outfall E

Outfall Area E drains the Fuels Management Area, or more commonly known as the POL 400 Area. It serves as the main storage and distribution facility for fuels. The POL 400 Area receives diesel fuel and MOGAS from commercial fuel trucks and JP-8 via pipeline from the POL 6000 Area or commercial fuel truck. This area consists of 10 aboveground storage tanks (ASTs) and an administration and operations building. There is also vehicle parking for R-11 fuel trucks. This area is included as an individual outfall area due to its high volume of material handled, the potential risk of spills, and the presence of a stormwater collection system.

The tank farm consists of the following ASTs:

• One 50,000-gallon tank for MOGAS

• Two 50,000-gallon tanks for diesel

• Two 480,0000-gallon tanks for JP-8

• Three 560-gallon JP-8 additive tanks

• One 2,000-gallon JP-8 additive tank

• One 1,000-gallon JP-8 additive tank.

The tanks in the Fuels Management Area are considered Industrial Activity under the stormwater discharge regulations. The primary potentially polluting materials handled in this area are JP-8, diesel, and MOGAS.

At the fill stand area, loading and unloading of fuels takes place. Four fill stands are used for JP-8 loading and off-loading and three are used for MOGAS and diesel. MOGAS and diesel are also transferred to vehicles through dispensers at the automated service station.

Spills occurring at the fill stand and fuel truck parking areas would be contained by secondary containment berms and/or catch basins and routed to oil/water separators that capture the first flush. After the initial flush, subsequent stormwater is inspected and then passed through the stormwater system.

Stormwater from all secondary containment dikes are either discharged to the storm drainage system or routed to an oil/water separator and then to the sanitary sewer.

Stormwater is inspected for any evidence of sheen prior to discharge to the storm drainage system. During storm events, personnel at the POL 400 Area shut the valve to the oil/water separator in order for that line to fill with stormwater. Once the line has filled with stormwater, all remaining water is properly routed to the storm drainage system. After such a storm event, the OWS valve is reopened and is allowed to enter the sanitary sewer system.

This method of controlling was intended to be a temporary solution since it does allow some clean to enter the sanitary sewer system. However, funds have never been allocated to allow for the installation of a proper diverter valve system, which would alleviate this problem.

The outfall area encompasses 14 acres and is 87 percent impervious. The runoff from the Fuels Management Area is collected in drains in the dikes around the tanks and flows through a concrete pipe to the ground adjacent to the north and west sides of the area.

The drainage area for Outfall E is shown in Figure A-6 in Appendix A. The photos below show the current outfall conditions.

3.3.6 Outfall F

Outfall F is the barge off-loading dock located at Shoal Point Bayou. The area is more commonly known as the POL 6000 Area and contains the greatest volume of fuel on Tyndall AFB. The facility primarily serves as a storage and distribution point for JP-8. The area contains eight ASTs and one UST. The ASTs within individual dike containment have capacities of 420,000; 820,000; and 838,000 gallons. Other ASTs include: two 12,000-gallon used oil tanks and two 560-gallon JP-8 additive tanks. There is one UST with a 6,000 gallon capacity at pump house 6042 that holds water.

Loading/unloading procedures in the POL 6000 Area are performed in accordance with Department of Transportation (DOT) regulations. Bowsers are brought to the POL 6000 Area from other areas of the base to be pumped out to the bulk ASTs. Spill response kits are located next to fillstands and on tank trucks, allowing for timely response to spills. Transfer hookups and lines are labeled and protective booms are deployed during barge offloading events. These bowsers are parked within a concrete curbed area that is restrained by a valve.

Spills in the vicinity of the loading dock during receipt JP-8 from fuel barges could enter Shoal Point Bayou. However, spills due to offloading almost never occur because of active BMPs in place. The outfall area covers approximately 13 acres, 61 percent of which is impervious. Stormwater runoff from the area is collected in the dikes around the tanks. It is inspected then released into swales before being discharged to the Bayou. Stormwater outside of the dikes is directed to a headwall before being released directly to Shoal Point Bayou.

The drainage area for Outfall F is shown in Figure A-7 in Appendix A. The photo below depicts the connection of Outfall F to the bayou.
