Laughlin Air Force Base

21 October 2016

About This Plan

This installation-specific Environmental Management Plan (EMP) is based on the U.S. Air Force’s (AF) standardized Storm Water Pollution Prevention Plan (SWPPP) template. This plan is not an exhaustive inventory of all storm water requirements and practices. Where applicable, external resources, including

Air Force Instructions (AFIs); AF Playbooks; federal, state, local, and country specific Final Governing

Standards (FGS) or Overseas Environmental Baseline Guidance Documents (OEBGD); and permit requirements, as applicable, are referenced.

Each section of this SWPPP begins with standardized, AF-wide “common text” language that addresses

AF, Department of Defense (DoD), and federal requirements, including the Environmental Protection

Agency (EPA) General Permit. This common text language is restricted from editing to ensure that it remains standard throughout all plans. The common text language is maintained and updated by the designated Office of Primary Responsibility (OPR) with assistance from the Office of Collateral

Responsibility (OCR), as appropriate. Immediately following the AF-wide common text sections are

Installation sections. The Installation sections contain installation-specific content to address state, local, and installation-specific requirements. Installation sections are unrestricted and are maintained and updated by installation or Installation Support Team (IST) personnel.

This document is optimized to be accessed and viewed electronically. The eDASH website at https://cs1.eis.af.mil/sites/edash/ is the primary communication tool for AF EMPs.

1.0 OVERVIEW AND SCOPE

This Storm Water Pollution Prevention Plan (SWPPP) specifies how wing personnel prevent discharges to storm water of potential pollution from industrial operations. It contains procedures intended to minimize the risk of industrial storm water pollution in drainage areas located within the base’s boundaries. The

SWPPP describes installation:

Identification and evaluation of activities and potential storm water pollution sources;

Identification and implementation of storm water Best Management Practices (BMPs);

Pollution reduction measures and procedures; and

Monitoring and inspection procedures.

The Wing Storm Water Pollution Prevention Team (SWPPT) is responsible for developing, implementing, and managing the SWPPP.

47th Flying Training Wing Supplement – Overview and Scope

Background

The Texas Pollutant Discharge Elimination System (TPDES) Multi-Sector General Permit (MSGP) identifies 30 industrial activity sectors that could obtain industrial storm water discharge permit coverage under the MSGP. Activities at Laughlin Air Force Base (AFB) fall within four of those sectors, which are outlined in the industry-specific sections of the permit guidance. The four sectors include:

Sector S, Air Transportation Facilities (where vehicle and equipment maintenance, including rehabilitation, mechanical repairs, painting, fueling, lubrication, deicing, and cleaning occurs);

Sector K, Hazardous Waste Storage Facilities (includes facilities with activities directly related to the treatment, storage, and disposal of hazardous wastes, including those that are operating under regulatory authority and authorization of subtitle C of the Resource Conservation and Recovery

Act [RCRA]);

Sector P, Land Transportation and Warehousing (includes motor freight transportation facilities, passenger transportation facilities, petroleum bulk oil stations and terminals, rail transportation facilities and United States Postal Service [USPS] transportation facilities); and

Sector N, Scrap and Waste Recycling Facilities (e.g., metals, paper, plastic, cardboard, glass, animal hides, used oil, antifreeze, mineral spirits, industrial solvents, computers, electronics, and other materials listed in the Standard Industrial Classification [SIC] Code Manual under SIC 5093).

A majority of regulated industrial activity at Laughlin AFB falls under Sector S. Examples include refueling, aircraft maintenance, aerospace ground equipment (AGE) maintenance, materials handling, equipment cleaning, and runway cleaning. The 47th Civil Engineer Squadron, Environmental Element (47

CES/CEIE) operates the hazardous waste storage facility activities and programs associated with Sector K.

RCRA treatment and disposal activities are not conducted on Laughlin AFB. The Compliance section of the Environmental Element, maintains the RCRA permit and associated programs for this storage facility.

The bulk fuel tanks located on Laughlin AFB, which store Jet-A, diesel, and unleaded gasoline, fall under

Sector P.

Facility Description

Laughlin AFB is located in Val Verde County, Texas, approximately 6 miles east of Del Rio, Texas, on

U.S. Highway 90. Laughlin AFB is located approximately 150 miles west of San Antonio, Texas, and approximately 7 miles inside the United States Rio Grande River Border with Mexico. The base spans approximately 5,343 acres.

The 47th Flying Training Wing at Laughlin AFB is one of five Air Education and Training Command pilot training units and conducts specialized undergraduate pilot training for the United States Air Force. More than 3,300 people in total live and work at Laughlin AFB.

Those aspects of the Laughlin AFB mission that have the potential to impact storm water include the fueling and maintenance of aircraft, ground vehicles, and AGE.

Drainage Areas, Outfall Descriptions, and Receiving Waters

The average annual precipitation in the region is approximately 18 inches. Consequently, storm water flows tend to accumulate in dry pond areas on base and subsequently evaporate or percolate into the soil.

However, in the event of a heavy rain event, storm water will flow off base via Zorro Creek, unnamed tributaries into Sacatosa Creek, and sheet flow. Laughlin AFB is divided into four main drainage areas, Drainage Areas 1, 2, 3, and 4.

Drainage Areas

The storm water drainage paths for each drainage area are described in the following sections. The Drainage

Areas and the Outfall Relationship Table shows the drainage areas that contribute storm water flow to each outfall and the outfall designation. No industrial activities are located in Drainage Areas 3 and 4.

Drainage Area 1

Most of the flight line and the majority of the industrial areas on base are located in Drainage Area 1. Storm water is collected through a storm water drainage system that includes culverts, ditches, and underground storm sewers. Generally, runoff from the industrial areas is diverted to an underground storm sewer and then into a large, grassy channel that runs along 2nd Street. Storm water runoff from the flight line is diverted to an underground storm sewer that runs under 1st Street, parallel to the storm water channel. This storm line empties into the channel approximately 400 feet northwest of the Fire Training Area.

The channel flows across the base in a grassy swale and discharges through Outfall 001 to an unnamed tributary of Sacatosa Creek at a point about 75 feet southeast of the facultative sewage treatment ponds, which lies along the southern property line.

Drainage Area 2

Drainage Area 2 includes three sub-drainage areas (i.e., 2A, 2B, and 2C) with industrial activity. These areas discharge storm water from within Drainage Area 2 through three separate outfalls. Storm water discharges from each sub-drainage area, as well as storm water flows from the remainder of Drainage Area

2, accumulate in a dry pond area at the west end of the base. The dry pond area drains directly into an ephemeral portion of Zorro Creek through Outfall 002.

Drainage Area 3

Drainage Area 3 primarily includes storm water runoff from municipal areas of the base including housing areas, golf course, clinic, and commercial areas. Storm water in Drainage Area 3 flows through the golf course ponds and accumulates in a dry pond area at the south end of the base and then flows off-base through Outfall 003. Drainage Area 3 is not subject to permitting due to the lack of industrial areas in this drainage area.

Drainage Area 4

The majority of Drainage Area 4 is open land with the exception of a portion of the runways. Since few exposure areas are located in Drainage Area 4, storm water runoff from this area is not subject to Sector S of the MSGP. Runway rubber removal is an activity that occurs in the drainage area and is subject to storm water exposure. The runway rubber removal is completely cleaned up, minimizing exposure. There is the potential for incidental training exercises requiring the movement of Aerospace Ground Equipment (AGE) to Goulds Gultch in Drainage Area 4. All AGE personnel are trained in spill response and the management of their equipment during normal operations. The only "Aircraft Support Equipment Maintenance" that takes place in Drainage Area 4 is associated with the radar (Vortec) and associated back-up generators. The generators are located on concrete pads. During heavy rain events, a majority of the storm water flows leave the base from Drainage Area 4 via sheet flow that can contribute to other drainage areas and to

Sacatosa Creek to the east or Zorro Creek to the north. Outfall 004, which consists of two separate culverts, is located at the eastern boundary of Laughlin AFB and is a point of discharge for Drainage Area 4.

Outfalls

A description of Outfalls 001 and 002 are provided in the following sections.

Outfall 001

Outfall 001 is located at the southeastern end of the base approximately 75 feet from the easternmost sewage treatment pond and leads to an unnamed tributary. During heavy rains, storm water flow from Drainage

Area 1 leaves the base and discharges directly into this unnamed tributary that flows into Sacatosa Creek.

Drainage to this Outfall is from a portion of the flight line and the majority of the industrial areas on base including the Hazardous Waste Storage Area.

Outfall 002

Outfall 002 is located along the western base property line, approximately 1,100 feet south of the Southern

Pacific Railroad tracks. Storm water in Drainage Area 2 accumulates in a dry pond that drains directly to an ephemeral portion of Zorro Creek through Outfall 002 during heavy rain events. Drainage to this outfall occurs mainly via the natural contours of the land (i.e., as opposed to constructed ditches or culverts) by sheet flows that result in the accumulation of storm water in a dry pond located at the western portion of

Drainage Area 2. The outfall is essentially a dry pond and not an obvious point of departure for storm water.

Outfall 02B

Outfall 02B is a heavily eroded channel with sparse vegetation that discharges on base within Drainage

Area 2. Drainage to this outfall includes storm water runoff from vehicle maintenance areas and fueling.

Discharges to this outfall flow toward the dry pond on the northwestern side of the base, which empties into Outfall 002 during heavy rain events.

Outfalls 02A and 02C

Outfalls 02A and 02C are culverts that discharge to the dry pond area on the northwest side of the base within Drainage Area 2. Drainage to this outfall includes runoff from the petroleum, oil, and lubricant

(POL) satellite accumulation area, jet fuel offloading area, and the industrial area bound to the northeast by

Liberty Drive, to the northwest by Arkansas Avenue, to the southwest by 4th Street, and to the southeast by Colorado Avenue. Discharges to this outfall flow toward the dry pond on the northwestern side of the base which empties into Outfall 002 during heavy rain events.

Drainage Areas Contributing to Outfalls

The Summary of Drainage Area Activities/Impervious Area Table summarizes the percentage of impervious surface area for the drainage areas. The percentage of impervious surface area indicates how much storm water could be expected to drain from the area. Generally, areas with a high percentage of paved surfaces tend to contribute a greater degree of runoff to storm water flows than do areas with a lower percentage of impervious surface area.

The Summary of Drainage Area Activities/Impervious Area Table also summarizes the principal industrial activities related to Sectors K, P, S, and N conducted in each drainage area. As indicated in this table, Drainage Areas 1 and 2 have the greatest potential for affecting storm water flows and quality since they have a sizable area, a high percentage of impervious surface area, and since significant industrial activities are performed in both areas. Information concerning the percentage of impervious cover for the drainage areas was calculated using current geographic information system (GIS) data. Although the exact percentages of impervious area for Drainage Areas 3 and 4 are unknown, they are relatively low. Drainage

Area 3 is primarily comprised of golf course grounds and residential housing and other municipal type facilities. Drainage Area 4 is mainly open land on the northeast side of the base, but air transportation related industrial activities do occur in this drainage area.

A Municipal Separate Storm Sewer System (MS4) permit is not requrired for non-industrial area on Laughlin Air Force Base at this time. Laughlin is located outside of an urbanized area (UA) as defined by the Bureau of the Census, and the TCEQ has not designated Laughlin AFB as Regulated MS4.

The plans and recommended changes will be addressed during the SWPPT meeting.

5.0 TRAINING

The wing implements storm water training programs to ensure that base personnel, contractors, and visitors are aware of their roles in the program and the importance of their participation to its success. DoDI

4715.10, Environmental Education, Training, and Career Development, implements policy and provides the procedures for environmental education, training, and career development programs for DoD personnel.

The installation ensures that appropriate personnel complete required education, training, and certification necessary to perform their jobs. Priority is given to the use of AF-approved education/training sources such as Air Force Institute of Technology (AFIT) training courses and official AF-approved computer-based training resources (e.g., ESOHTN, ADLS, ArcNet, etc.) to meet training needs.

Specific training requirements may be outlined in Storm Water Control Measures in Section 7.2. Training records are maintained IAW the Recordkeeping and Reporting section of this plan.

47th Flying Training Wing Supplement – Training

Employee Training

Laughlin AFB employees that have the potential to impact the environment are trained in pollution prevention. These programs focus on the responses necessary in the event of a pollutant release to ensure the safety of personnel and protection of the environment. These programs are outlined below:

Spill Response Plan Training: The Spill Prevention, Control, and Countermeasures (SPCC) Plan for Laughlin AFB establishes personnel training requirements, contractor training requirements, Spill Response Team training, and emergency contingency training. In addition, the following will be included:

o Under the Clean Water Act (CWA), owners or operators should schedule and conduct spill prevention briefings for their operating personnel at intervals frequent enough to ensure adequate understanding of the SPCC Plan. Such briefings should highlight and describe known spill events or failures, malfunctioning components, and recently developed precautionary measures.

Emergency Response Training: The Laughlin AFB Facility Response Plan identifies training requirements for personnel responsible for stopping a release, containment and control of a release, and clean-up of a release. The fire department is the first responder to accidents and spills and has the training and materials necessary to control most spills and procedures for getting help and safeguarding people when a spill is beyond their control.

Hazardous Waste Training: The hazardous waste training plan is included in the Laughlin AFB

Hazardous Waste Management Plan. Base personnel whose jobs entail working with hazardous waste or who are exposed to hazardous waste are required to be properly trained as required under

EPA and Occupational Safety and Health Act (OSHA) regulations. United States Air Force

(USAF) hazardous waste training covers the following subjects in addition to the most current federal and state requirements and installation policies:

o Introduction to RCRA;

o Identification of hazardous waste;

o Accumulation point management;

o Container use, marking and labeling, and on-site transportation;

o Waste turn-in procedures;

o Manifesting and transportation of hazardous waste;

o Spill prevention and response for emergencies; and o Personnel safety and health and fire safety.

CWA Required Training: Under the CWA, owners or operators of storage facilities are responsible for properly instructing their personnel in the operation and maintenance of equipment to prevent discharges of oil and applicable pollution control regulations and rules.

RCRA Required Training: Under RCRA, facility personnel must successfully complete a program of classroom instruction and on-the-job training that teaches them to perform their duties in a way that ensures the facility's compliance.

Good Housekeeping/BMP Training: Facility personnel will be trained at intervals frequent enough

(i.e., annually) to provide an adequate understanding of the good housekeeping and facility-specific storm water BMPs implemented at Laughlin AFB. This training plan will include instruction regarding material management practices to reduce waste generation through material substitution, improved materials handling, and process enhancements.

6.0 RECORDKEEPING AND REPORTING

The wing implements measures to ensure compliance with applicable permit recordkeeping and reporting requirements. Records are stored and maintained IAW Air Force Manual 33-363, Management of Records, and records are archived and disposed IAW the Air Force Records Information Management System

(AFRIMS) Records Disposition Schedule (RDS). The wing complies with all permit reporting requirements.

The wing maintains the following inspection, monitoring, and certification records with the SWPPP. When possible, a link to the electronic version of the record is made available in the references section of this plan.

Copy of the Notice of Intent (NOI);

Copy of the acknowledgement letter containing the permit tracking number;

Copy of the permit;

Description and dates of any significant spills, leaks, or other releases (Note: the installation maintains this information in EASI, and a link is available in the references section of this SWPPP);

Employee training records;

Documentation of maintenance and repairs of control measures;

Inspection reports;

Documentation of deviations from the schedule for monitoring or assessments and the reason for the deviation;

Documentation of corrective actions taken;

Documentation of benchmark exceedances and how they were addressed; and

Documentation to support determination that pollutants of concern are not expected to be present above natural background levels if water is discharged directly to impaired waters.

Additional state, local, or host nation recordkeeping and reporting requirements are described in the

Installation Supplement, as necessary.

47th Flying Training Wing – Recordkeeping and Reporting

Recordkeeping and Internal Reporting Procedures

A description of spills and leaks, storm water sampling data, preventive maintenance and routine inspections, personnel training, site compliance evaluation reports, and releases of storm water from containment areas are to be documented and retained on the environmental section share drive. All incidents that require an action or incidents of noncompliance are to be documented. These records are to be used to devise improvements in the management practices after they have been analyzed. It is the responsibility of the Laughlin AFB Water Quality Program Manager to ensure that all incidents are documented in this plan and then followed up with the proper corrective action. Records must be updated as appropriate.

Per MSGP Part III.D.5, monitoring and reporting records, copies of all other records required by this general permit, and records of all data used to complete the application for this general permit must be retained at the facility or must be made readily available for review upon request by authorized Texas Commission on

Environmental Quality (TCEQ) personnel as well as any local pollution control agency with jurisdiction for a period of three (3) years from the date of the record or sample, measurement, report, application, or certification. This period must be extended at the request of the executive director.

The SWPPP must be maintained, and be made readily available for inspection and review upon request by authorized TCEQ personnel as well as any local pollution control agency with jurisdiction. Additionally, a copy of all SWPPPs for the preceding three (3) year period must be maintained and made readily available for review. In circumstances where the number of revisions to the SWPPP makes this requirement burdensome, a log or record of revisions for the preceding three (3) year period may be maintained and made available.

If the general permit is terminated or allowed to expire without renewal, the SWPPP must be maintained and made readily available for review for a minimum period of one year following cessation of permit coverage.

Records Retention

The SWPPP, all records of monitoring information, and copies of all reports required by the MSGP, must be retained for a minimum of three (3) years from the dates of sampling, examination, and other activity that generated the data. The records are maintained up-to-date and electronically by the Laughlin AFB

Water Quality Program Manager on eDASH and the Laughlin AFB Water Quality Program Manager’s electronic files.

7.0 PROCEDURES - STORM WATER POLLUTION PREVENTION PLAN

7.1 Potential Pollution Sources

Areas at the installation where industrial materials or activities are exposed to storm water are described in the Installation Supplement below.

Documentation of significant spills is maintained in the Enforcement Actions, Spills and Inspections

(EASI) database. A link to EASI is available in the references section of this plan, and necessary information may be maintained in Appendix B.

Activities, Associated Pollutants, and Potential Spills

Inventory of Exposed Material

Appendix C provides a list of the significant materials identified on Laughlin AFB, their location, and quantity stored. In addition to the materials included in Appendix C, pallets and uncontrolled dumpsters

(i.e., not covered/sealed, corroded), parking areas, runways, and construction areas are considered to be significant materials that could potentially affect storm water quality. A general evaluation of these materials is detailed in Section 7.2, Storm Water Control Measures.

Pollution Risk Identification and Summary of Potential Sources

Exposure areas contain potential sources of storm water pollution identified in the base survey. The

Potential Source and Drainage Data Table summarizes these exposure areas, the respective materials, and the outfalls and drainage areas associated with each source.

In general, the principal materials associated with various exposure areas and corresponding handling practices with the potential for release and subsequent contamination of storm water flows are:

Fuels (jet fuel, diesel, unleaded gas);

Oils, lubricants, and greases (from storage, from waste generation, from vehicles and aircraft, and from roadways, runways, and parking areas);

Jet fuel and oil mixture;

Aircraft cleaner (CitriKleen);

Paint wastes;

Scrap metal;

Solvents; and

Antifreeze.

These materials can impact storm water quality by increasing biochemical oxygen demand, chemical oxygen demand, total suspended solids, nitrogen, phosphates, whole effluent toxicity, and toxic chemical concentrations. Potential releases from the exposure areas associated with the buildings listed in the

Potential Source and Drainage Data Table can affect receiving waters downstream of the outfalls.

Unauthorized Non-Storm Water Discharges

Surveys of the sanitary sewer system on Laughlin AFB have been conducted to identify cross-connections and areas of non-compliance. The results of these surveys have been used to ensure the integrity of the system and to prevent unauthorized non-storm water discharges.

Routine visual inspections of outfalls, building design reviews and compliance assessments are also used to identify non-storm water discharges. The MSGP allows certain non-storm water discharges documented in the SWPPP (listed below). Pollution prevention measures are outlined in Appendix F, Procedures to

Minimize Runoff Contamination.

Authorized non-storm water discharges at Laughlin AFB include:

Discharges from firefighting activities, not including fire training exercises;

Fire hydrant flushing;

Potable water sources including lateral or building waterline flushing;

Lawn watering and similar irrigation drainage;

Routine external building wash-down without the use of detergents or other compounds;

Routine washing of pavement without the use of detergent or other chemicals and where spills or leaks of toxic or hazardous materials are not present;

Air conditioning condensate discharge;

Springs and uncontaminated groundwater infiltration or runoff;

Foundation or footing drain discharges without contamination from process materials such as solvents; and

Uncontaminated water used for dust suppression.

Additionally, non-storm water discharges can include wastewater streams permitted under an alternative

TPDES permit (i.e., sewage treatment pond effluent from Wastewater Outfall A).

Identification and Evaluation of Non-Storm Water Sources

Tetra Tech conducted a non-storm water investigation in September 2016. The inspection occurred during a dry weather event. All industrial outfalls were inspected for any signs of water. Tetra Tech did not observe any non-storm water releases while conducting the Comprehensive Site Compliance Inspection

Materials Handling Practices and Potential Releases

The materials handling practices discussed in this section relate to the materials inventory as described in

Appendix C. These practices include storage methods and steps taken to avoid potential releases into storm water drainage flows. In the remainder of this plan, areas with the potential to contaminate storm water

(e.g., outdoor storage areas, industrial activity areas) are referred to as exposure areas. Potential releases from specific exposure areas are detailed in this section.

General Materials Handling Measures

Most outside material storage areas at Laughlin AFB are controlled to prevent or reduce the risk of storm water runoff contamination. These controls include:

Curbing, dikes, or berms around storage areas;

Covered or enclosed material storage areas;

Spill containment pallets for material storage drums; and/or

Drip pans underneath drum spouts.

A general survey of the base showed that dumpsters used for storing non-hazardous solid waste outside industrial and non-industrial buildings are kept covered and are replaced with new or refurbished dumpsters when they become corroded.

Specific BMPs for materials handling are described in greater detail in Appendix F.

Drum Tracking and Labeling Practices

Drums at Laughlin AFB are labeled to indicate their contents to allow for quick and proper response to releases of stored materials that could affect human safety, the environment, or storm water discharges. A computerized waste drum tracking system is employed to track the generation, storage, and disposal of wastes (e.g., RCRA waste drums). The system tracks drums by barrel numbers, which are assigned to all waste drums. Information from the completed Form 1348-1, Disposal Turn-In Document, which accompanies each waste drum transferred to the Defense Logistics Agency (DLA) is entered into the computer tracking system.

POL Spills, Leaks, and Drip Pan Use

Rainwater collected in secondary containment areas for POL product and waste storage is visually inspected before the water is drained. If contaminants are suspected or sheen is present, the water is analyzed before it is drained. Generally, all tanks and storage containers are maintained using a regular inspection and repainting schedule. Drip pans are also used as necessary to contain minor leaks from fuel lines, valves, and drains. These measures are practiced to reduce the potential for releases to storm water flows.

Runoff Management Practices

Most outside material storage areas at Laughlin AFB are controlled to prevent or reduce the risk of storm water runoff contamination through runoff management practices. These practices include earthen or concrete berms around all tanks, diked exposure areas, storage of materials inside buildings, and a retention/evaporation pond. The curbing or dikes around storage areas are provided to contain spills and/or rainwater off-spray that impacts storage tanks, drums, and bins.

In addition, spill control measures are implemented as soon as a spill is discovered to prevent the material from entering storm drainage channels. These spill control measures are site-specific and are detailed in the Laughlin AFB SPCC Plan.

Specific Exposure Areas

The material handling practices and/or industrial activities conducted at various exposure areas can affect the storm water quality. Appendix D summarizes the specific industrial activities and their associated buildings on Laughlin AFB that can impact storm water quality.

Detailed material handling methods and potential releases for the material storage areas, which are identified by their relative proximity to adjacent buildings, are also listed in Appendix D. These are exposure areas that can be affected by rain events, and thus can affect storm water discharges.

Good Housekeeping Program

Good housekeeping practices are currently exercised at Laughlin AFB. Numerous USAF policies and procedures dictate good housekeeping practices and are rigorously enforced at all levels of management.

Generally, these procedures involve four key areas:

Procedures to minimize the use of chemicals susceptible to exposure and runoff;

Procedures to keep exposure areas clean;

Procedures to minimize runoff contamination; and

Specific procedures for exposure areas and activities addressed earlier in this Section.

Of these areas, the first three involve procedures that are generally implemented throughout Laughlin AFB, where applicable. The fourth area deals with specific procedures for particular exposure areas and/or activities. These procedures are therefore more localized to address specific storm water pollution prevention needs at key locations at Laughlin AFB.

Procedures to Minimize Chemical Use

Laughlin AFB currently implements the following procedures to minimize the use of chemicals susceptible to exposure and runoff. Generally, these procedures include inventory reduction and product substitution/elimination and are employed throughout the base, where applicable.

Hazardous Material Inventories: The amount of hazardous materials is closely controlled through the maintenance of up-to-date hazardous material inventories and labeling of all hazardous material containers in accordance with U.S. DoD Directive 4210.15, Hazardous Material Pollution

Prevention Act of 1990. Tracking such materials reduces the risk of spills by limiting the quantity of stored materials to that which is needed (i.e., fewer excess materials on- hand).

Pollution Prevention Opportunity Assessment: If conditions arise which warrant it, a pollution prevention opportunity assessment will be accomplished. The results of the assessment will be used to:

Assemble and review data concerning the processes, operations, and waste management practices within a defined area; and

Identify potential waste minimization alternatives using the collected data.

These objectives will be met by collecting and reviewing data from the field inspection and identifying pollution prevention alternatives for specifically identified waste streams. These alternatives may include process modifications that substitute toxic chemicals or reduce the amount of materials used that could affect storm water quality.

Procedures to Maintain Clean Exposure Areas

The following procedures are implemented throughout Laughlin AFB, where applicable, to keep exposure areas clean, thereby reducing the potential for storm water contamination:

Spill Containment Pallets: Self-contained spill containment pallets are used throughout the Base to serve as secondary containment in the event that a drum leaks or ruptures.

Material Storage and Handling Practices: Materials are stored indoors to minimize exposure when possible. Materials that are stored outdoors are covered and otherwise protected from storm water contact/run-on.

Procedures to Minimize Runoff Contamination

Appendix F lists procedures that are implemented throughout Laughlin AFB to minimize the potential for storm water runoff contamination.

Best Management Practices

In addition to the specific procedures previously recommended, the BMPs outlined in the Best Management

Practices for Specific Exposure Areas of Laughlin AFB Table are implemented to prevent and/or control storm water pollution from the specific exposure areas identified in this section.

The following text contains descriptions of the BMPs that are referred to in the Best Management Practices for Specific Exposure Areas of Laughlin AFB Table.

Material Handling and Storage Practices: As indicated in this section, the current liquid storage practices at many of the exposure areas have the potential to pollute storm water runoff. Where indicated in the Best

Management Practices for Specific Exposure Areas of Laughlin AFB Table, the following BMPs will be employed to prevent contamination of storm water runoff:

Materials Stored Indoors: When feasible, materials will be stored indoors to prevent exposure to storm water.

Drip Pans: Temporary or permanent drip pans are used to catch drips from valves, pipes, hoses, drains, vehicles, etc., so that the materials or chemicals can be easily cleaned up or recycled before they can contaminate storm water. Drip pans are used as preventive measures; although useful as temporary solutions for containing leaks, the necessary repairs should be performed immediately.

Drip Pans will be available and be used under construction equipment whenever parked.

Containment Diking: Exposure areas are diked to provide protection against the contamination of storm water by surrounding the area of concern and isolating the runoff for subsequent analysis prior to release (i.e., to the storm drainage system or sanitary sewer system).

Electrical Grounding: Tanks and drums are grounded for sparks to avoid potential explosions and subsequent spills.

Locked Funnels: Lids on waste drum funnels are locked to prevent access by personnel without proper authorization. By limiting access to materials, the chance for spills, mixing of materials or chemicals, and improper handling are reduced.

Locked Containment Discharge Drain: Containment discharge drains are locked to prevent access by personnel without proper authorization. Rainwater collected in POL containment areas is visually inspected for contamination prior to draining.

Good Housekeeping: Exposure areas clean are kept clean and tidy and chemical use is minimized in areas susceptible to exposure and runoff. Erosion and sediment controls will be used during construction, operations and maintenance, and the like including rock socks and other best management practices.

Regular Inspection: Drums and tanks are inspected regularly to ensure that storage conditions are adequate.

Spill Kits: Spill kits are present at most exposure areas to provide timely response to accidental releases. Additional spill kits will be provided, where needed.

Covering: Materials are covered to prevent exposure to storm water.

Corrosion Protection: Drums are placed on polyvinyl chloride (PVC) footings or pallets to keep the drums out of containment water, thereby reducing the potential for corrosion by preventing moisture contact with the drums.

Traffic Guards: Protective guards are installed around tanks and piping in high traffic areas to prevent vehicle or forklift damage to the tanks.

Overflow Protection: Overflow protection devices are installed on tank systems to warn the operator or to automatically shut down transfer pumps when a tank reaches full capacity.

Drum Replacement: New or refurbished drums are used to replace old drums as needed to ensure that materials/chemicals are adequately stored in reliable drums.

Labeling: Drums, tanks, pipes, and equipment are clearly tagged or labeled. Labels on tanks and drums indicate the type of material and container contents. Two effective labeling methods are color-coding and Department of Transportation (DOT) labeling. Accurate labeling can help base personnel quickly identify the type of material released so that personnel can react accordingly.

Transportation: Materials are transported to a lower exposure area.

Leak Checks: Storage containers are periodically checked for leaks and are…
