1. Introduction

This Storm Water Pollution Prevention Plan (SWPPP) has been prepared by Luke Air Force Base (AFB) located in Glendale, Arizona. This SWPPP addresses the pollution prevention requirements of the National Pollutant Discharge Elimination System (NPDES) Storm Water Multi-Sector General Permit for Industrial Activities (MSGP-2000). This plan has been prepared in accordance with good engineering practices and the requirements of the MSGP-2000 as outlined in the Federal Register, Vol. 65, No. 210/Monday, October 30, 2000. This SWPPP revision replaces the 2004 SWPPP and does satisfy the MSGP-2000 requirements.

The three major requirements of this SWPPP are to: (1) identify potential sources of pollution which may affect the quality of storm water discharges associated with the industrial activities performed at Luke AFB; (2) describe and ensure implementation of practices to minimize and control pollutants in storm water discharges from these industrial activities; and (3) ensure compliance with the terms and conditions of the MSGP-2000.

1.1 Contents of the SWPPP

The SWPPP is presented in the same sequence and format as the MSGP-2000, Part 4.

1.2 Regulatory History and the Luke AFB Storm Water Program

1.2.1 Regulatory History

In 1972, the Federal Water Pollution Control Act, which became the Clean Water Act (CWA), was amended to require that the discharge of pollutants to waters of the United States from any point source be covered by a NPDES permit. The 1987 amendments to the CWA added Section 402(p), establishing a framework for regulating municipal and industrial discharge of storm water under the NPDES program.

Final regulations establishing application requirements for regulated storm water discharges were published in the Federal Register on November 16, 1990. The regulations require that facilities with specific types of industrial activities that also discharge storm water obtain an NPDES permit. On September 29, 1995, the US Environmental Protection Agency (US EPA) issued its general permit for industrial activities. Under these regulations, aviation operations and treatment work operations are considered "industrial activities." Industrial activity at an aviation facility is defined in the MSGP-2000 as including those portions of the facility involved in vehicle maintenance (including vehicle rehabilitation, mechanical repairs, painting, fueling, and lubrication), equipment cleaning operations and deicing operations. Industrial activity at a treatment works facility is defined in the MSGP-2000 as any domestic sewage treatment works with a design flow capacity of at least 1.0 million gallons per day. Areas throughout the Base that engage in industrial activities are, therefore, required to be permitted under the industrial NPDES program. Effective October 30, 2000, US EPA reissued the Multi-Sector General Permit for industrial activities (MSGP-2000). The Arizona Department of Environmental Quality (ADEQ) is currently the agency designated with primacy for administering this federal program and they have developed Arizona-specific requirements which were developed and included as part of the 401 certification process. These Arizona-specific requirements can be found via the ADEQ website.

1.2.2 Luke AFB Storm Water Compliance Program

Luke AFB has been identified as an industrial facility covered under 40 CFR 122.26(b)(14) Subparts viii & ix and has obtained permit coverage for storm water discharges under the US EPA’s MSGP-2000, effective October 30, 2000. Luke AFB received approval of its Notice of Intent (NOI) seeking coverage under MSGP-2000 (AZMSG-9899) from ADEQ on March 1, 2004. A copy of the NOI approval is included as Attachment 1.

Originally, Luke AFB participated in the Air Force Group Application for a NPDES permit to discharge storm water from an industrial facility. The Environmental Protection Agency (EPA) subsequently took all of the group applications and developed a single permit known as the NPDES Baseline General Permit for Storm Water Discharges from Industrial Activities, which was eventually replaced by the Multi-Sector General Permit in September 1995. Luke AFB was issued NPDES Storm Water Multi-Sector General Permit coverage on 5 April 1996, and on 5 May 1996, the permit number was changed from AZR05A021 to AZR05AO1F.

1.3 Luke AFB Storm Water Pollution Prevention Plan Certification

Based on my inquiry of the person or persons who managed the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations.

Charles J. Rothrock

Date Chief, Environmental Flight

In accordance with Part 9.7 of the permit (65 FR 64853), the individual listed above is empowered to make this certification. Any other individual making this certification must be designated as a signatory authority, based on written delegation of authority from the Environmental Flight Chief.

2. SWPPP Requirements

2.1 Storm Water Pollution Prevention Team (SWP2 Team)

MSGP-2000, Part 4.2.1 requires the Base to establish a SWP2 Team. The Team is responsible for developing, implementing, maintaining, and revising the SWPPP. The SWP2 Team is comprised of representatives with a variety of functions and responsibilities that will help the Base ensure that all aspects of its operations are considered.

The SWPPP must identify the team members by title or name as well as their specific responsibilities. The SWP2 members are identified in Table 1. Primary responsibility for administering the Storm Water Compliance Program and for maintaining and updating the SWPPP rests with the Water Program Manager. Membership on the team is based on area of responsibility because staffing changes are common in this environment. Therefore, participation of specific individuals will change as members transfer from their current positions to others or leave the Base. The Team is a “working group” under the Environmental Safety and Occupational Health Management System (ESOHMS) Sub-Committee, which reports to the Environmental Safety and Occupational Health Council (ESOHC) chaired by the Vice Wing Commander. Members of the SWP2 Team must receive annual SWPPP training.

2.2 Site Description

2.2.1 Facility Activities

This section contains a description of the nature of industrial activities at Luke AFB as per MSGP-2000 Part 4.2.2.1. The Base is home to the 56th Fighter Wing of the Air Education and Training Command’s (AETC) 19th Air Force. The mission of Luke AFB is to train the world’s greatest F-16 fighter pilots and maintainers while deploying mission ready war-fighters. Although F-16 fighter jets are the primary aircraft assigned to Luke AFB, a variety of other Air Force and non-Air Force aircraft have access to Luke AFB on a short-term basis.

The Base is located at 33o32’25”N, 112o21’30”W; or as portions of Sections 3, 4, 5, 7, 8, 9, 10, 16, 17 and 18 of Township 2 N/S, Range 1 E/W of the Gila and Salt River Base and Meridian, Maricopa County, Arizona. The Base is a fully operational military installation that encompasses approximately 4359 acres (including land held in fee and easements). The Base was originally built in 1941 as a military training installation and has since undergone several expansions and reconstructions. Luke AFB averages approximately 150 sorties per training day on two active runways. Approximately 55 percent of the facility is covered by impervious surfaces (runways, taxiways, and parking lots) and buildings. Pervious surfaces, which comprise the remainder of the facility, are concentrated around the runways and in the non-navigable areas of the Base. The surrounding area consists of residential, industrial and commercial property. There are 12 outfall locations in the existing storm drain system (NOTE: the number of outfalls and outfall locations will change once Storm water modeling in GIS is completed).

Luke AFB is one facility that functions within two land areas; the main Base and the WWTF Annex. These areas are large and non-contiguous. The Base has numerous industrial shops, its own water treatment facility, wastewater treatment facility, fire department, police department, medical clinic, dental clinic, grocery and general merchandise store, movie theater, bowling alley, gas station, restaurants/cafeterias, dormitory housing, single family housing and motel. Luke AFB is analogous to a small city that surrounds an airport.

In addition to the general MSGP-2000 requirements, Luke AFB is subject to the requirements of the following sectors of MSGP-2000: S. Air Transportation Facilities and MSGP-2000: T. Treatment Works. Luke AFB is also responsible to adhere to any sector-specific requirements for co-located industrial activities on-site that are described in a sector(s) other than the primary sectors; these additional requirements must also be included in the SWPPP. These extra sector-specific requirements apply only to those areas of the facility where the extra-sector activities occur. (MSGP-2000, Part 1.2.1.1)

The primary industrial activities at this facility include:

1. Aircraft, Ground Vehicle and Equipment Maintenance

2. Aircraft, Ground Vehicle and Equipment Cleaning

3. Aircraft, Ground Vehicle and Equipment Awaiting Maintenance Storage

4. Outdoor Handling and Storage of Non-RCRA/HAZWASTE and HAZMAT

5. Outdoor Fuel Delivery/Dispensing

6. Waste Water Treatment and Storage of Biosolids The applicable Standard Industrial Code(s) (SIC) for site activities are 4581, and 4952.

Sector S (Air Transportation Facilities) Related Activities This is the primary sector of the MSGP-2000 applicable to Luke AFB. Luke AFB’s primary mission is to train F-16 fighter pilots. The primary function of the industrial shops on Base is to support that mission. These shops cover a variety of activities but are generally classified as vehicle (including aircraft) maintenance areas and equipment cleaning areas.

Aircraft are serviced in the hangars and on the apron. Preventative maintenance is allowed on the apron while major alterations and repairs are only allowed in designated areas where dry clean-up methods are used. Waste oil generated from maintenance activities is temporarily stored in sheltered containers with secondary containment until they are disposed of off-site by a waste fluid disposal company. Materials such as lubricating oils, hydraulic oils, degreasers, and other cleaning products are commonly used. Small leaks or spills of these materials are not uncommon during maintenance activities. Personnel respond to these leaks and spills by following the installations Spill Prevention, Control and Countermeasures (SPCC) Plan. Some of the common materials used to clean up spills are absorbent socks/pads, dry absorbent materials, rags, and mops. Maintenance activities represent a low potential for significant pollutant discharge at Luke AFB.

Aircraft washing is also performed at Luke AFB. Aircraft washing is performed only at the aircraft wash rack. The facilities are graded to prevent runoff. Wash water is captured and routed through an oil water separator before being discharged to the sanitary sewer. Vehicle and equipment washing is performed at the six wash racks designated for vehicles and equipment. Aircraft, vehicle, and equipment washing is a minor source of storm water pollution.

There is minimal temporary storage of aircraft, vehicles and equipment at Luke AFB. During rain events, any residues (fuel, oil, grease) on the equipment under repair, or residuals from chemical spills or leaks from the stored aircraft, vehicles or equipment could be a source of potential pollutants in storm water discharges. Storage activities represent a minor source of storm water pollution.

Some Base shops store chemicals and petroleum, oil, lubricant (POL) products (i.e. gasoline, diesel, and jet fuel). Most shops have indoor storage areas to house these items. Chemicals, POL and waste POL are typically stored in 55-gallon drums or smaller containers. Fuel is typically stored in underground or aboveground storage tanks. Other materials such as cleaners, paints, and paint-related products are stored in smaller containers. Shops are responsible for using secondary containment in chemical storage areas during the course of normal operations. Outdoor storage areas have the greatest potential to impact storm water.

Fueling activities are conducted only on paved surfaces. Fuel spills may occur quite frequently due to the frequency with which this activity is performed; however few spills actually enter the storm drain. Spills are contained by absorbent materials and are cleaned up.

Fuel storage is done either in aboveground and underground tanks. Fueling can be performed from transfer trucks or directly from the subsurface storage system. Fuel delivery and transfer trucks are equipped with automatic fuel shut-off valves that provide spill protection during filling operations thereby minimizing fuel exposure to storm water on the apron. Leaks from fuel transfers that are not immediately cleaned have the greatest potential to impact storm water.

Building and grounds maintenance activities include pesticide and herbicide spraying and painting. The Base operates its own pesticide management facility with fully trained personnel who are aware of the proper quantities and applications of these products. The facility is designed for storing and mixing the pesticides which will isolate spills from storm water. The facility has never had a spill and little potential to pollute storm water will occur here. Fertilizer application is handled by professional grounds-men under contract. It is in their best financial and legal interests as contractors to apply only the proper quantities of fertilizers. In addition, much of the landscaping in the industrial areas of Luke AFB is xeriscape or desert and receives little or no fertilizer application. Large scale painting operations are restricted to special paint booths where paints and strippers are managed properly by trained personnel. Painting using spray cans is only permitted in designated paint booths. This activity appears to present a low potential for impacting storm water discharge.

Luke AFB does use glycol-based fluids but not for deicing purposes; the chemicals are primarily used in vehicle maintenance operations. The amount of glycol-based fluids used at Luke AFB is very low (<10,000 gallons per year and the MSGP-2000 threshold for benchmark monitoring is 100,000 gallons per year); therefore as per MSGP-2000, Part 5.1.2, Table 5-1, only quarterly visual monitoring is required. MSGP-2000, Part 6.S.5.2 requires that the SWPPP contain a record of the types of deicing chemicals used (including the Material Safety Data Sheets or MSDSs) and the monthly quantities consumed. All this information can be found at the installations Primary HAZMART/Hazardous Materials Management Center (HMMC).

Sector T (Treatment Works) Related Activities

The Luke AFB WWTF was designed to treat 1.2 MGD and current loading is approximately 0.4 MGD. The WWTF is governed by both an Arizona Pollutant Discharge Elimination System (NPDES) Permit for effluent discharge to the Agua Fria River and an Aquifer Protection Permit for discharge to underground aquifers.

The original WWTF was constructed in the 1940s and modified in 1993-94. The current treatment facility includes the following major components: Air Flotation Basin, Manual Bar Screen, Aerated Grit Chamber, Micro Strainer, Anoxic Basins, Oxidation Ditch, Secondary Clarifiers, Lift Stations, Tertiary Sand Filtration, Ultra-Violet (UV) Disinfection System, Effluent Re-use Holding Pond, Sludge Holding Tank and Sludge Drying Beds. Material removed by the Micro Strainer is automatically collected in a large container at the headworks. The Anoxic Basins, Oxidation Ditch and Tertiary Sand Filter are constructed with sufficient freeboard to handle even large amounts of rainfall and the walls are sufficiently high to prevent runoff. The clarifiers and most pump stations are constructed below grade with sufficient freeboard to prevent runoff. UV disinfection is used rather than chlorination/dechlorination; therefore, chlorine is not stored or used on the facility. Sludge is stored in the holding tank or in the drying beds, which are concrete lined and have been designed to contain a certain volume of sludge and any rainfall that may occur during the drying process. How the WWTF manages sludge can be found in the Biosolids On-site Management Plan.

The WWTF is located on a relatively level piece of land with little of the facility paved. The runoff coefficient for the site is quite low (less than 30%) and a 6- to 7-ft high block wall has been constructed around three sides of the facility (the downstream sides of the facility). Overall, there is little potential for runoff to occur from this facility and very little potential to pollute storm water.

Sector T requires only quarterly visual monitoring of grit screenings and other solids handling/storage/disposal areas, sludge drying beds, dried sludge piles and outfalls.

2.2.2 General Location Map

Figure 1 is the General Location Map. The map shows the location of the facility and the receiving waters within one mile as per MSGP-2000 Part 4.2.2.2.

2.2.3 Site Map

NOTE: The Luke AFB Site maps are in the process of being developed – storm water flow modeling and infrastructure validation must be completed in the GIS database first before a valid site map can be produced.

Figure 2 is the Site Map for the Main Base Area and Figure 3 is the Site Map for the Wastewater Treatment Facility Annex. These maps present the following information which is required as per MSGP-2000 parts 4.2.2.3 and 13.9.2.6:

· Direction of storm water flow

· Location of structural BMPs

· Location of surface water bodies

· Location of potential storm water pollution sources (identified in section 2.4)

· Location of major spills or leaks (identified in section 2.5)

· Locations where the following activities are exposed to storm water: fueling stations, vehicle/equipment maintenance and/or cleaning, loading/unloading areas, treatment/storage/disposal of wastes, liquid storage tanks

· Locations of storm water outfalls and an approximate outline of the area draining each outfall

· Location and description of non-storm water discharges

· Locations where the following activities are exposed to storm water: processing and storage areas, access roads/rail cars and tracks, transfer of substances in bulk, machinery

· Location and source of runoff from adjacent property containing significant pollutants of concern

· Delineation of the 100-year floodplain. (Note that Luke AFB property has been identified on Flood Insurance Rate Map No. 04013C1685E and Map No. 04013C1245G as Zone X, which are areas of 500 year flood; areas of 100-year flood with average depths of less than 1 foot or with drainage area less than 1 square mile; and areas protected by levees from 100-year flood.)

Table 2 contains a list of the Luke AFB storm water outfalls.

2.3 Receiving Waters and Wetlands

MSGP-2000 Part 4.2.3 requires that the SWPPP identify the nearest receiving water(s) that may receive discharges from the facility. The Agua Fria River is the named receiving water for storm water discharged from the Base. There are several unnamed ephemeral washes surrounding the Base that drain into the Agua Fria River.

2.4 Summary of Potential Pollutant Sources

MSGP-2000 Part 4.2.4 requires that the SWPPP identify each separate area on the Base where industrial materials or activities are exposed to storm water; the associated potential pollutants from each identified area are also to be listed. Table 3 identifies the potential pollutant sources, the potential pollutants and the associated drainage points for each source (facilities can be listed under more than one industrial activity). Site assessments were conducted by the Water Program Manager for each area/facility to determine which were/could be potential pollutant sources. All site assessments were documented and are currently maintained electronically by the Water Program Manager.

The potential pollutant sources have not varied significantly since the start of the Luke AFB Storm Water Management Program. The most common potential pollutants are POL products, solvents, sealants, soap/cleaning fluid, anti-freeze, paint, battery acid, pesticides, and sludge. These pollutants can be transported to the storm water system either as direct spills, from rainfall runoff, or from surface area wash downs that may mobilize residual contaminants.

2.5 Spills and Leaks

MSGP-2000, Part 4.2.5, requires that the SWPPP identify areas where potential spills and leaks that are exposed to storm water can occur and their accompanying drainage points. A list of all significant spills and leaks of toxic or hazardous pollutants that occurred in the three years prior to the date of the submission of an NOI to be covered under this permit and all significant spills/leaks that occur while covered by the MSGP-2000 must be maintained. Significant spills include, but are not limited to, releases of oil or hazardous substances in excess of quantities that are reportable under Section 311 of the CWA or Section 102 of the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). Significant spills may also include releases of oil or hazardous substances that are not in excess of reporting requirements and releases of materials that are not classified as oil or a hazardous substance.

Potential spills and leaks on Luke AFB are most likely to occur at the potential pollutant sources identified in section 2.4 and Table 3 of this SWPPP; the associated drainage points for these potential pollutant sources is also included in Table 3. Table 4 lists all significant spills and leaks that have occurred from three years prior to submitting an NOI for coverage under the MSGP-2000 to now. Luke AFB has in place a spill response program which is outlined in Operational Plan (OPlan) 705, Hazardous Materials Emergency Planning and Response Plan. Within OPlan 705 there are three levels of spills identified. All OPlan 705 level 3 spills will be considered significant and will be listed. To be considered a level 3 spill, it must: pose an extreme threat to life or property; will migrate off site and expose individuals off site; require expertise or resources from the county, state, federal or private agencies or organizations; exceed 2,100 gallons of petroleum; involve munitions; or require large scale evacuation.

2.6 Sampling Data

MSGP-2000 Part 4.2.6 requires that the SWPPP summarize the sampling requirements and data for the facilities. Luke AFB is required to perform quarterly visual monitoring based on the requirements of the applicable industrial sectors (S and T) and as outlined in the MSGP-2000 Part 5.1.1.

2.6.1 Visual Monitoring

The storm water samples are qualitatively assessed by inspecting the sample for color, odor, clarity, floating solids, settled solids, suspended solids, foam, oil sheen, or other obvious indicators of storm water pollution. Monitoring is done at each outfall location by collecting grab samples of storm water discharge resulting from a storm event that is greater than 0.1 inch in magnitude and occurs at least 72 hours from the previous storm event that generated measurable discharge. The monitoring results are included in Attachment 2. All monitoring records shall be retained as part of the SWPPP for a minimum of 3 years from the date of the sampling, examination, or activity that generated the data.

2.6.2 Analytical Monitoring

MSGP-2000 Part 5.1.2, Table 5-1 and Part 6.S.6, Table S-1 requires analytical monitoring for glycol-based fluids used in deicing aircraft, equipment, and runways if the facility uses more than 100,000 gallons in a year. Luke AFB does not trigger this threshold, therefore analytical monitoring is not required.

MSGP-2000 Part 5.1.2, Table 5-1 does not require analytical monitoring for industrial sector T but does require additional visual monitoring of: access roads, grit, screenings and other solids handling/storage/disposal areas, sludge drying beds, dried sludge piles, compost piles, septage or hauled waste receiving station areas. The WWTF has an AZPDES Permit, a Type 2 Reclaimed Water General Permit and an Aquifer Protection Permit to monitor the wastewater discharges.

2.7 Storm Water Controls

In the context of storm water pollution prevention, Best Management Practices (BMPs) include any “processes, procedures, schedules of activities, prohibitions on practices, and other management practices that prevent or reduce the discharge of pollutants in storm water runoff” (MSGP-2000 Fact Sheet, 65 FR 64763). MSGP-2000, Part 4.2.7.1, requires that a description be given for each non-structural and structural BMP that is currently in use or is planned to be used in areas where industrial activities or materials are exposed to storm water (potential pollutant sources). Luke AFB has taken the following factors into consideration in selection of BMPs:

1. The quantity and nature of the pollutants, and their potential to impact the water quality of the receiving waters

2. Opportunities to combine the dual purposes of water quality protection and local flood control benefits

3. Opportunities to offset the impact of impervious areas of the facility on ground water recharge and base flows to local streams Luke AFB has developed BMPs based on the requirements and guidelines of the MSGP-2000 Part 4.2.7.2 and the applicable industrial sector specific requirements that address pollutants originating from those regulated activities.

Attachment 3 outlines the BMPs that apply to each of the identified industrial activities that Luke AFB performs.

The following is a list of the BMPs that were selected:

· Good Housekeeping

· Minimizing Exposure

· Preventive Maintenance

· Spill Prevention and Response Procedures

· Routine Facility Inspections

· Employee Training

· Sediment and Erosion Control

· Management of Runoff

· Other Controls

2.7.1 Planned or In-place Non-Structural, Structural and Other Controls for Luke AFB that are Not Industrial Sector Specific Planned Non-Structural BMPs

There are no additional non-structural BMPs planned for Luke AFB at this time.

In-place Non-Structural BMPs As a general practice, Luke AFB personnel adhere to the following non-structural BMPs:

1. Good Housekeeping – Luke AFB personnel regularly pick up trash and debris around facilities, trash containers, storage areas and loading docks.

2. Routine Facility Inspections – Luke AFB is required (IAW Air Force policy) to conduct multiple facility inspections, which cover a broad range of topics, on a recurring basis.

Planned Structural BMPs

The following is a list of planned structural BMPs that will be implemented on Luke AFB as funding becomes available:

· Bank stabilization for outfall 008 (southwest of bldg 1236 near the munitions area)

· Bank stabilization for Dysart drain near the southeast corner of Falcon Dunes golf course

· Repair/Replace grates for outfall 003

· Construct secondary containment for POL tank storage room in bldg 291

· Install booms at outfalls 004, 005 and possibly 008

In-place Structural BMPs

The following is a list of structural BMPs currently in place at Luke AFB:

· An industrial Oil Water Separator located at facility 912

· Secondary containment for storage tanks that require it (as per SPCC Plan)

· Swales/Retention basins throughout the facility

· Asphalt and concrete paving throughout most areas where industrial activities occur

Planned Other Controls

There are no additional other controls planned for Luke AFB at this time.

In-place Other Controls

· For construction projects that will disturb more than one acre of land, Arizona Department of Environmental Quality requires the contractor/base create and implement a site specific storm water pollution prevention plan which addresses controlling track-out and if necessary velocity dissipation devices.

· For earth moving projects over 1/10 acre, Maricopa County requires the contractor/base obtain an earth moving permit and implement a fugitive dust control plan.

3. Maintenance

MSGP-2000 Part 4.3 requires that the structural BMPs identified in the SWPPP be maintained in effective operating condition. If site inspections reveal BMPs that are not operating effectively, maintenance must be performed prior to the next anticipated storm event, as soon as is practicable, or as necessary. Non-structural BMPs must also be maintained and modified as necessary in order to be pertinent.

4. Non-Storm Water Discharges

Non-Storm Water Discharge Certification

I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gathered and evaluated the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations.

In reference to MSGP-2000, Part 4.4.1, I certify, under penalty of law, that all discharges (i.e. outfalls) have been evaluated for the presence of non-storm water. Luke AFB is required to conduct dry weather screenings in accordance its Storm Water Management Plan (SWMP); these dry weather screenings fulfill MSGP-2000 Part 4.4.1 and are contained in Attachment 2. In addition to visual dry weather screenings, Luke AFB conducted a storm sewer study in 2004. The study did not cover the entire storm sewer system but focused primarily on the portion where the majority of the industrial activity occurs.

In accordance with Part 9.7 of the permit (65 FR 64853), the individual listed above is empowered to make this certification. Any other individual making this certification must be designated as a signatory authority, based on written delegation of authority from the 56 Fighter Wing Commander.

The following chart outlines which of the allowable non-storm water discharges Luke AFB expects to have per MSGP-2000 Part 4.4.2:

2. Design deluge (foam) testing system with the following characteristics:

· Located away from storm drain inlets, drainage facilities or water bodies. Discharge foam waste to a sanitary sewer (industrial wastewater permitting may be required). Foam waste shall not be discharged to storm drains or water bodies.

· Paved with concrete or asphalt, or stabilized with an aggregate base.

· Bermed to contain foam and to prevent run-on.

· Configure discharge area with a sump to allow collection and disposal of foam.

3. Regularly inspect, clean, and maintain fire fighting foam testing facility and collection sumps.

2. To prevent soil erosion the following must be applied in order:

· If possible, attach a hose to the fire hydrant and put the other end of the hose directly into the storm sewer/drain.

· If possible, flush hydrant via hose or directly onto a paved surface that has been cleaned of debris and flows to the storm sewer/drain.

· If hydrant flushing must occur over bare soil then structural controls must be implemented to prevent soil erosion (examples include: placing geo-textile material on exposed soil in the discharge path, using rip-rap, using check dams, using devices to dissipate flow velocity, using storm inlet protection, etc.)

2. To prevent soil erosion the following must be applied in order:

· If possible, attach a hose to the water line and put the other end of the hose directly into the storm sewer/drain.

· If possible, flush water line via hose or directly onto a paved surface that has been cleaned of debris and flows to the storm sewer/drain.

· If water line flushing must occur over bare soil then structural controls must be implemented to prevent soil erosion (examples include: placing geo-textile material on exposed soil in the discharge path, using rip-rap, using check dams, using devices to dissipate flow velocity, using storm inlet protection, etc.)

2. Use drip pans, absorbent booms, mats, or other devices to contain/collect leaking water.

2. Minimize use of pesticides, herbicides, and fertilizers. Use according to directions. Utilize integrated pest management.

3. Develop working relationships with surrounding farmers in order to better control what’s in the irrigation run-on and/or convince farmers to divert run-on from coming onto Luke AFB.

2. Consider the following design characteristics for grounds / landscaping design:

· Incorporate areas of landscape into project design. (Landscape areas are pervious and will result in less runoff discharge from a site.)

· Incorporate design considerations such as leaving or planting native vegetation to reduce irrigation, fertilizer, and pesticide needs.

· Select landscaping plants that require little maintenance and/or pest control.

· Incorporate storm water detention/retention to reduce peak runoff flows and for water quality control.

3. Minimize use of pesticides, herbicides, and fertilizers. Use according to directions. Utilize integrated pest management.

1. If possible use a different cleaning method than hosing and washing (e.g. broom sweeping, shovels, vacuum cleaners, etc.).

2. Properly dispose of landscape waste, sweepings, sediments and all other debris prior to washing pavement. If an area is not cleaned prior to washing then all storm drain inlets downstream of the flow that may receive the wash water must be protected/blocked so that the dirty water does not enter the storm sewer system.

2. For Monitoring wells refer to BMP(s) listed below:

· When installing a monitor well follow all the requirements outlined by the Arizona Department of Water Resources.

· When installing a monitor well in bare earth sites, drill-rig track out must be prevented by using appropriate measures (tire washing, rumble ‘strips’, etc.).

· For sampling that is done on a monitor well located in a remote/unpaved area:

i. If monitor well must be purged prior to taking water samples then the purged water will either be collected and disposed of down a sanitary sewer system or released upon the ground that surrounds the monitor well – if necessary structural controls will be implemented to prevent soil erosion (e.g. pour water on vegetated areas/groundcover, place geo-textile material on exposed soil, etc.).

· For sampling that is done on a monitor well located in a paved area:

i. If monitor well must be purged prior to taking water samples then the purged water will either be collected and disposed of down a sanitary sewer system or released upon the ground that surrounds the monitor well – flow path area must be cleaned of all debris prior to releasing the water.

5. Documentation of Permit Eligibility with Regard to Endangered Species

Permit Eligibility Related to Endangered Species Certification

I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gathered and evaluated the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations.

In reference to MSGP-2000 Part 4.5 and Part 1.2.3.6, I certify, under penalty of law, that no endangered or threatened species or critical habitat are in proximity to Luke AFB or the point where authorized discharges reach the receiving water. Luke AFB has assessed the impacts of its storm water discharges, allowable non-storm water discharges, and discharge-related activities on Federally listed endangered and threatened species and designated critical habitat and has concluded that its activities do not result in any prohibited “takes” of listed species, and that Luke AFB is eligible for coverage under Criteria A of the MSGP-2000.

In accordance with Part 9.7 of the permit (65 FR 64853), the individual listed above is empowered to make this certification. Any other individual making this certification must be designated as a signatory authority, based on written delegation of authority from the 56 Fighter Wing Commander.

MSGP-2000 Part 4.5 requires that the SWPPP include documentation supporting the determination of permit eligibility with regard to Part 1.2.3.6 – Endangered Species. The documentation must include:

· information on whether listed endangered or threatened species, or critical habitat, are found in proximity of the facility

· whether such species may be affected by storm water discharges/discharge activities

· results of Addendum A – endangered species screening determination

· a description of measures necessary to protect listed endangered or threatened species and critical habitat

Addendum A is a step by step process to determine if endangered species/critical habitat are in proximity to a facility and to determine the impact the facilities storm water discharge will have on endangered species/critical habitat. Documenting the results of Addendum A fulfills the required documentation needed for this section.

5.1 Addendum A Documentation

Step One: Are there any endangered species or critical habitat in your county and if so, are they in proximity to your facility or discharge locations?

1-A. Check of Listed Species. Luke AFB is located in Maricopa County, Arizona. The county species listing for Maricopa County, AZ indicates five bird, five fish, one mammal, and one plant species as follows:

· Arizona Cliff-rose (Purshia subintegra)

· Bald Eagle (Haliaeetus leucocephalus)

· California Brown Pelican (Pelecanus occidentalis californicus)

· Desert Pupfish (Cyprinodon macularius)

· Gila Chub (Gila intermedia)

· Gila Topminnow (Poeciliopsis occidentalis)

· Lesser Long-Nosed Bat (Leptonycteris curasoae yerbabuenae)

· Mexican Spotted Owl (Strix occidentalis lucida)

· Razorback Sucker (Xyrauchen texanus)

· Southwestern Willow Flycatcher (Empidonax traillii)

· Woundfin (Plagopterus argentissimus)

· Yuma Clapper Rail (Rallus longirostris yumanensis) Source: U.S. Fish & Wildlife Service, March 2008 1-B. Check for Critical Habitat. Luke AFB has reviewed 50 CFR part 17 and part 226 and determined that only six of the above species have designated critical habitat. Neither Luke AFB nor its discharge locations are within designated critical habitat. According to 50 CFR part 17 there is no critical habitat located in the Phoenix, AZ metropolitan area, within which Luke AFB is located.

1-C. Check for Proximity. Listed species are in proximity to a facility when they: are located in the path or immediate area through which or over which contaminated point source storm water flows from industrial activities to the point of discharge, are located in the vicinity of the discharge point, or are located in an area of the facility where storm water BMPs are planned to be constructed. Using the results of 1-B (researching 50 CFR parts 17 and 226) and using the Visual Inspection Procedures identified in the MSGP-2000 – Addendum A, Luke AFB has concluded that none of the listed species are identified in proximity to the facility. In addition to the visual inspection, Luke AFB has project-related correspondence with the U.S. Fish & Wildlife Service (USFWS) and the Arizona Game & Fish Department (AGFD) to identify the occurrence or potential occurrence of protected species. In 1994 an in-depth inventory of the vegetation, wildlife, and wildlife habitat which occurs within the boundaries of the base and the WWTF was conducted. The results of this study along with annual updates are recorded in the Luke AFB Integrated Natural Resources Management Plan. Therefore Luke AFB is not required to take special measures to protect endangered species/critical habitat because nothing of this sort is located in the proximity of the base.

1-D. Check for Criteria “A” Eligibility. If no species were listed for your county or the species that were listed were not in proximity to your discharge and your facility and discharge locations were not in proximity to critical habitat you are eligible under criteria ‘A’. The species listed for Maricopa County, AZ were not in proximity to the Base discharge AND the facility and discharge locations are not in proximity to critical habitat, therefore the Base has met the permit eligibility criteria with regard to Endangered Species under Criteria A and therefore can proceed to step five.

Step Five: Submit Notice of Intent and document results of the eligibility determination.

5.2 Criteria A Required Documentation

To be eligible under Criteria A the following documentation is required to be a part of the SWPPP: A copy of the County-Species List pages where your facility and discharges are located and a statement on how you determined that no listed species or critical habitat was in proximity to your discharge. A copy of the Maricopa County Species List is located in Attachment 4. The statement regarding how Luke AFB determined that no listed species or critical habitats were in proximity to its storm water discharge follows:

Luke AFB determined that no listed species or critical habitats were in proximity to our storm water discharge by using two methods:

· Performing an in-depth review of 50 CFR part 17 for each of the listed species on the Maricopa County Species List

· Performing a visual inspection (as outlined in MSGP-2000, Addendum A) The result of these two methods was that no endangered species or critical habitats were in the proximity of the Luke AFB storm water discharge.

6. Documentation of Permit Eligibility with Regard to Historic Places

MSGP-2000 Part 4.6 requires that the SWPPP include documentation supporting the determination of permit eligibility with regard to Part 1.2.3.7 – Historic Places. The documentation must include:

· information on whether storm water discharges/discharge-related activities would have an effect on property listed or that is eligible for listing on the National Register of Historic Places

· any written agreements made with the State/Tribal Historic Preservation Officer if historic places are affected by storm water discharges/discharge-related activities

· results of Addendum B – historic places screening determination

· a description of measures necessary to avoid or minimize adverse impacts on places listed or eligible for listing on the National Register of Historic Places Addendum B offers three scenarios to determine eligibility under the MSGP-2000:

1. If historic properties are not identified in the path of the facilities storm water discharges or in the path of storm water BMP construction areas then the applicant has met the permit eligibility criteria under Part 1.2.3.7.1

2. If historic properties are identified but it is determined that they will not be affected by the facilities storm water discharges or storm water BMP construction areas then the applicant has met the permit eligibility criteria under Part 1.2.3.7.1

3. If historic properties are identified in the path of the facilities storm water discharge or in the path of the storm water BMP construction areas and it is determined that there is a potential to adversely affect the historic property then the applicant can still meet the permit eligibility criteria under Part 1.2.3.7.2

Addendum B offers permit applicants two methods to determine if a facilities storm water discharge or storm water BMP construction area will affect historic properties. The first method, and most recommended, is to access the National Park Service’s online National Register Information System (NRIS) and do a search for listed/eligible for listing historic properties that surround the facility. The second method is to contact the State/Tribal Historic Preservation Office and request a list of listed/eligible for listing historic properties that surround the facility.

Luke AFB elected to use NRIS which revealed 318 listed and 53 eligible for listing historic places in Maricopa County. Luke AFB also consulted its own Integrated Cultural Resources Management Plan (ICRMP) to determine if storm water discharges would adversely affect surrounding historic places. Neither NRIS nor the ICRMP revealed any historic property that would be adversely affected by storm water discharge or storm water BMP construction around Luke AFB. Therefore Luke AFB has determined that no storm water discharges or storm water BMP construction area has the potential to affect a property that is either listed or eligible for listing on the National Register of Historic Places. Luke AFB meets the permit eligibility criteria of MSGP-2000 Part 1.2.3.7.1.

7. Copy of Permit Requirements

MSGP-2000 Part 4.7 requires that the SWPPP include a copy of the MSGP-2000 permit. A copy of the MSGP-2000 is located in Attachment 5.

8. Applicable State, Tribal, or Local Plans

This SWPPP is consistent with the applicable State and local storm water, waste disposal and sanitary sewer regulations that are more stringent than the requirements of the MSGP-2000 permit; this fulfills the requirement of MSGP-2000 Part 4.8.
