EXECUTIVE SUMMARY
This document represents the Dallas-Fort Worth International Airport (DFW Airport) Stormwater
Management Program (SWMP), a comprehensive pollution prevention plan that incorporates
both structural and non-structural control measures and waste reduction protocols designed to
manage and improve the quantity and quality of stormwater runoff that is ultimately discharged to
receiving surface waters. The DFW Airport SWMP defines the philosophy and system utilized to
ensure Airport Board employees, airport contract workers, airport tenants and co-tenants, tenant
contractors, developers, travelers, visitors, and nearby communities understand the potential
consequences of stormwater pollution, best practices to reduce stormwater pollution, and the
ramifications (both environmental and legal) of failing to apply environmental management
practices into current policies, procedures, and designs.
In 1990, the Environmental Protection Agency (EPA) promulgated the rules associated with the
Phase I of the National Pollutant Discharge Elimination System (NPDES) program. The
purpose of the Phase I stormwater1 program was to reduce the discharge of pollutants to waters
of the United States from three primary sources:
▪ Operators of medium and large municipalities,
▪ Construction activities disturbing greater than 5 acres, and
▪ Operators of industries classified in at least one of 11 identified industrial categories.
Phase II of the NPDES program, issued in 2007, addresses stormwater discharges from
construction activities disturbing one to five acres of land as well as stormwater discharges from
small municipalities located in urbanized areas (as defined by the U.S. Census Bureau). The rule
requires that small municipalities employ a stormwater program to reduce the discharge of
pollutants to receiving waters to the maximum extent practicable (MEP). Thus, municipalities are
required to implement a stormwater program which addresses six minimum control measures
(MCMs):
1 Stormwater discharges are generated by runoff over land and impervious areas such as paved streets, parking lots and building rooftops during rainfall, snow events, or other precipitation events. Stormwater flows across exposed surfaces where it can pick up various pollutants that could adversely affect water quality. Stormwater runoff is considered a major source of water pollution, and continues to significantly impact the quality of our nation’s waters.

2. Illicit Discharge Detection and Elimination (IDDE)
3. Construction Site Stormwater Runoff Control
4. Post-Construction Stormwater Management in New Development and Redevelopment
5. Pollution Prevention and Good Housekeeping for Municipal Operations
6. Industrial Stormwater Sources.
The Texas Commission on Environmental Quality (TCEQ) was delegated authority from the
United States EPA to administer the NPDES stormwater program on September 14, 1998. On
August 13, 2007, the TCEQ issued the Texas Pollutant Discharge Elimination System (TPDES)
TXR040000 Permit, which authorizes the discharge of stormwater to surface water of the state
from all small municipal separate storm sewer systems2 (MS4s) located in urbanized areas.
DFW Airport is subject to the TXR040000 Permit because DFW Airport is a public entity as
established under the Texas Transportation Code Chapter 22. Furthermore, DFW Airport is
located in an urbanized area between the cities of Dallas and Ft. Worth and holds jurisdiction over
a system designed for collecting and dispensing stormwater to waters of the U.S. To comply with
this permit, DFW Airport is implementing a program to reduce the discharge of pollutants (to the
MEP) to receiving waters, protect water quality, and satisfy pertinent water quality mandated by
the Clean Water Act (CWA) and the TPDES program.
2 According to the permit, an MS4 is a conveyance or system of conveyances (including roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, man-made channels or storm drains): (a) owned or operated by the United States, a state, city, town, borough, county, parish, district, association, or other public body (created by or pursuant to state law) having jurisdiction over disposal of sewage, industrial wastes, stormwater, or other wastes, including special districts under state law such as a sewer district, flood control district or drainage district, or similar entity, or an Indian tribe or an authorized Indian tribal organization, or a designated and approved management agency under the CWA 208 that discharges to surface water in the state; (b) designed or used for collecting or conveying storm water; (c) not a combined sewer; and (d) not part of publicly owned treatment works (POTW) as defined by 40CFR122.2

1.0 INTRODUCTION
Stormwater discharges have been identified as a significant source of water pollution in numerous
nationwide water quality studies. Unlike sanitary sewer collection systems that flow to wastewater
treatment plants, stormwater runoff generally discharges untreated into our nation’s creeks, rivers,
and other receiving waters (i.e. tributaries and lakes).
1.1 Regulatory Background
In 1972, the EPA established the CWA as the primary federal law regulating the discharge
of pollutants into Waters of the United States (WOTUS), with an overall objective to restore
our nation’s waters to Fishable and Swimmable. One of the requirements of the CWA
was to develop a regulatory program to reduce the pollution produced from stormwater
discharges. This program, managed by the EPA, is identified as National Pollutant
Discharge Elimination System (NPDES), and regulates stormwater discharges from
construction activities, industrial facilities, and various municipalities. The TCEQ is
delegated authority from the U.S. EPA to administer the NPDES stormwater program for
all regulated entities in the state of Texas.
1.2 Airport Regulatory Background
DFW Airport is covered under the previous TPDES general permit for small MS4s
(TXR040000, Issued and Effective on December 13, 2013) and must comply with the new
TXR040000 General Permit; this permit provides authorization for stormwater and certain
non-stormwater discharges from small Municipal Separate Storm Sewer Systems (MS4s).
DFW Airport is subject to this regulation because DFW Airport is considered a public entity
(as established under the Texas Transportation Code Chapter 22), is located in an
urbanized area, and holds jurisdiction over a system designed for collecting and
dispensing stormwater to waters of the U.S. To comply with this permit, DFW Airport must
implement a stormwater program designed to reduce the discharge of pollutants to the
maximum extent practicable3 (MEP), protect water quality, and satisfy pertinent water
quality requirements of the CWA and the TPDES program. As a small MS4, DFW Airport
3 Maximum Extent Practicable (MEP) refers to the technology-based discharge standard for municipal separate storm sewer systems to reduce pollutants in stormwater discharges that was established by CWA ' 402(p). A discussion of
MEP as it applies to small MS4s is found at 40 CFR ' 122.34.

has developed a Stormwater Management Plan (SWMP), a comprehensive pollution
prevention plan that incorporates both structural and non-structural pollution prevention
and waste reduction protocols designed to manage and improve the quality of discharges
entering the DFW Airport MS4 and receiving waters. The current MS4 permit categorizes
regulated small MS4s based on population served within the 2010 urbanized area
according to the US Census Bureau and defines an airport as a ”non-traditional MS4”.
DFW Airport is categorized as a Level 2 small MS4 and has thus developed a SWMP in
accordance with applicable permit requirements. A copy of the completed Notice of Intent
(NOI) and the TXR040000 permit are provided in Section 2.0 of this SWMP.

2.1 Airport Description
The DFW Airport Board (“Board”) is a joint board of the cities of Dallas and Fort Worth,
created by them through a Contract and Agreement dated April 15, 1968 (the “Contract
and Agreement”) pursuant to the Municipal Airports Act (now Transportation Code,
Chapter 22) to “plan, acquire, establish, construct, improve, equip, maintain, operate,
regulate, protect and police” DFW Airport. As a result of the Contract and Agreement,
DFW Airport is operated by the DFW Airport Board and is not governed by either the city
of Dallas or the city of Fort Worth. The Airport Board is composed of 11 members from
the owner cities, seven from the city of Dallas and four from the city of Fort Worth. Both
the mayor of Dallas and the mayor of Fort Worth sit on the Board. The remaining members
are appointed by the respective city councils of Dallas and Fort Worth. In addition, the
Board has one non-voting member who is selected by the cities of Coppell, Euless,
Grapevine, and Irving, respectively, on an annual, rotational basis.
The DFW Airport Board appoints a Chief Executive Officer (CEO), who is responsible for
overseeing the day-to-day operations at the airport. In addition to the CEO, the DFW
Airport Board appoints a General Counsel and Auditor, both of whom are independent of
the CEO and report directly to the Board. The CEO hires senior staff to manage the
various functions of the airport. Senior staff is comprised of Executive Vice Presidents,
who are responsible for hiring Vice Presidents and Assistant Vice Presidents to manage
and oversee the various Airport departments (Table 1).

2.2 Tenant Demographics
The Airport manages approximately 2,000 acres of leased land supporting 15 million
square feet of building space. The majority of the tenants that operate from DFW Airport
are either directly or indirectly related to the air transportation and cargo industries.
Tenants directly related to air transportation include the airlines and cargo companies, the
ground-support equipment (GSE) providers, and air fueling companies. Tenants indirectly
related to the air transportation industry include the rental car facilities, hotels, terminal
concessionaires and retail companies, and flight schools. The remaining tenants are not
related to the air transportation industry and include recreational facilities, restaurants,
warehousing, and light industrial facilities. With the construction of Terminal F along with
additional cargo and warehousing complexes, DFW Airport anticipates a significant growth
in both passenger travel and air freight during the next ten years.
A copy of the DFW Airport’s Land Use Plan Map is provided in Appendix A and provides
an overview of the extent and profile of DFW’s developed and undeveloped areas.

3.0 DESCRIPTION OF STORMWATER OUTFALLS AND DRAINAGE SYSTEMS
The direction that stormwater runoff flows at DFW Airport is based on the property’s topography
as well as the underground storm sewer and first flush stormwater pretreatment systems.
Stormwater collection systems operated by DFW Airport also receive discharges and discharge
into stormwater collection systems operated by neighboring municipalities (e.g. Fort Worth,
Grapevine, Irving). The majority of stormwater runoff at DFW Airport eventually discharges into
local creeks and tributaries. Waters of the U.S. either originating on or traversing across DFW
Airport property include the following: Grapevine Creek, Cottonwood Creek, Hackberry Creek,
South Fork Hackberry Creek, Mud Springs Creek, Estelle Creek, Cottonwood Branch Creek, Bear
Creek, Big Bear Creek, Little Bear Creek, and associated tributaries. These ten creeks discharge
into eight different watersheds within the boundaries of DFW Airport.
Figure 2: DFW Airport Watershed Map

Outfall areas draining stormwater at DFW Airport can be categorized into five primary groups,
according to the land use in the designated area. The first group includes outfalls draining areas
supporting light to heavy industrial activities. Many of these outfalls drain areas where
aircraft/vehicle fueling, aircraft/vehicle maintenance, GSE operations, or aircraft deicing/anti-icing
activities occur. The majority of vehicle, aircraft, or equipment maintenance activities occur
indoors; however, stormwater runoff may come into contact with pollutants associated with aircraft
deicing, fueling operations, and vehicle/equipment operations and storage that generally occur
outdoors.
The second major group of outfalls observed at DFW Airport is outfalls that drain only taxiway or
runway areas. Activities are normally limited to aircraft and emergency vehicle traffic only. No
industrial activities occur in these areas.
The third group of outfalls consists of undeveloped areas that may be used for the storage of
outdoor equipment and vehicles. Equipment stored in these areas is generally for outdoor use
(e.g. traffic signs, light poles, and earth-moving equipment). No industrial activities occur in these
areas.
The fourth group of outfalls observed at DFW Airport consists of areas draining either roadways
or parking areas. Activities in these areas would be limited to vehicle parking and
loading/unloading operations. No industrial activities occur in these areas.
The fifth group of outfalls observed at DFW Airport consists of those areas supporting DFW Airport
Board facilities and tenant facilities with either light commercial or no industrial activities (i.e.
facilities not subject to the TPDES MSGP4). Facilities included in this group include DFW Airport
office buildings and municipal facilities and various airport tenants including rental car facilities,
commercial gas stations, office buildings, food catering facilities, recreational facilities, and
4 Part I of the TPDES General Permit No. TXR05000 defines storm water discharges associated with industrial activity as “storm water runoff that exits any system that is used for collecting and conveying storm water that originates from manufacturing, processing, material storage, and waste material disposal areas (and similar areas where storm water can contact industrial pollutants related to the industrial activity) at an industrial facility described by one or more of Sectors A through AD of this general permit.”

warehouses or other commercial-type industries. Facilities in this group can be characterized by
municipal, commercial, office, or recreational use.
The DFW Airport Stormwater Outfall map is included in Appendix A and indicates property
boundaries, surface water bodies, stormwater outfalls, and associated contributing drainage
areas.
3.1 Storm Drainage System –Fuel Farm & Terminal and Cargo Ramp-Side
Most storm drain inlets located on the air-side ramp supporting terminal areas, deicing
areas, fueling areas, hangars, ground-support equipment maintenance areas, and some
cargo facilities contain fuel vapor traps and water level floats designed to retain oil and
grease by discharging the stormwater to a fuel separator. Dry weather and first flush
drainage from the terminals (airside), UPS Cargo Facility (ramp/apron area), North West
Cargo facilities, and the Allied Aviation fuel farm are discharged through fuel separators
to the Stormwater Pretreatment Plant located south of South Airfield Drive. The fuel
separators vary by size and design. Most structures contain one influent line and two
effluent lines. The smaller line located near the bottom of the structure discharges flows
to the airport’s first flush pretreatment stormwater line, which flows to the DFW Airport
Stormwater Pretreatment Plant. The larger line located above the invert of the smaller
line discharges flow to the storm sewer system. The fuel separators act as stormwater
structural controls and are designed to direct low flow and first flush stormwater discharges
to the Stormwater Pretreatment Plant. Flows which exceed the hydraulic capacity of the
first flush line are discharged from the diversion structure through the storm sewer system
to various creeks and tributaries.
Stormwater drainage from the Northeast Cargo (NE Cargo) ramp area discharges into fuel
separators, which can either direct flows to a lined stormwater drainage channel and then
to Hackberry Creek, or into a 203,000-gallon valve-controlled sump. The NE Cargo sump
is currently used for emergency spill containment only; any dry weather or unpermitted
discharges collected in the sump are vacuumed and transported to either the DFW Airport
Pretreatment Plant or disposed of offsite. During wet weather events and normal
-
12
operations, the sump valve remains open and stormwater runoff flows through the sump
valve to various stormwater outfalls discharging into Hackberry Creek. In the event of a
spill or a release, the sump valve can be closed as an engineering control to minimize
impacts to surface water or the environment.
3.2 Storm Drainage System -Terminal and Cargo Public-Side, Airfield, Airport Facilities, Tenant Facilities, and Roadways
Stormwater flows originating from airfield runway and taxiway areas discharge directly to
receiving waters, via DFW Airport’s stormwater collection systems. Similar to airfield
runways and taxiways, storm drain inlets supporting roadways, public-sides of Terminal
areas, general parking areas, DFW Airport offices and municipal buildings, most tenant
leaseholds, recreational facilities, and the rental car complex, also discharge directly to
the DFW Airport stormwater collection system, which in turn discharges flows to the
nearest receiving water or MS4. Some DFW Airport maintenance facilities and tenant
facilities are constructed with stormwater structural controls designed specifically to treat
first flush stormwater before its discharge into downstream waters or collection systems.
-
13
4.0 IMPAIRED WATERS AND ENDANGERED SPECIES
Per the MS4 Permit, discharges of pollutants of concern to impaired water bodies are not eligible
for coverage under the TXR040000 permit, unless discharges are consistent with an approved
TCEQ and EPA Total Maximum Daily Load (TMDL). On December 11, 2013, the TCEQ approved
the Implementation Plan for TMDL for Bacteria in the Greater Trinity River Region as submitted
by the North Central Texas Council of Governments (NCTCOG). DFW Airport is subject to the
TMDL permit requirements for a small area of drainage to the Elm Fork River tributaries of
Grapevine Creek and Cottonwood Branch Creeks (Segments 0822) as well as Bear Creek and
Big Bear Creek (Segment 0841). The goal for the Bear Creek, Cottonwood Branch, and
Grapevine Creek TMDL is to maintain concentrations of E. coli below the geometric mean criterion
of 126 MPN/100 mL.
4.1 Targeted Pollutants of Concern
The SWMP will address the discharge of bacteria to impaired waters and waters with
approved Total Maximum Daily Loads (TMDLs) and shall assess the progress in reducing
those pollutants throughout the term of the permit. DFW Airport implementation strategies
will focus on controlling potential sources of bacteria with proper management of sanitary
sewer systems, eliminating illicit discharges, and minimizing wildlife and domestic animal
inputs by utilizing applicable BMPs as outlined in the NCTCOG Regional Implementation
Plan. As required by the permit, an ongoing assessment of water quality improvements
will be addressed by reporting and evaluating analytical results for E. Coli through DFW’s
IDDE program and Watershed Monitoring programs. The Airport will also focus on
implementing BMPs which educate employees, tenants, and contractors on sanitary
sewer overflows, conducting preventative maintenance on sanitary structural controls,
encouraging employees and passengers to pick up pet waste.
In addition to the Minimum Control Measures detailed later in this plan, DFW Airport is
implementing the following targeted controls to reduce the discharge of bacteria into
impaired waters:
-
14
• The Airport will comply with the developed Sanitary Sewer System Operations and
Maintenance Manual which addresses the aspects included in a traditional
Capacity Management, Operation, and Maintenance (C-MOM) program. This plan
defines how DFW Airport employs proper maintenance programs and routinely
evaluates system capacities to minimize the occurrence of sanitary sewer
overflows (SSOs). A report summarizing all maintenance performed on the
sanitary sewer system and identifying the improvements that will be pursued for
the next fiscal year will be completed annually.
• DFW Airport is overseeing a grease recycling contract on behalf of terminal
concessionaires to facilitate food grease recovery and recycling. This activity is
intended to minimize the amount of food grease discharged to the sanitary sewer
system, which could contribute to the blockage of sanitary sewer pipes and the
occurrence of SSOs.
• The Airport will continue to develop and distribute educational materials to terminal
concessionaires regarding the importance of proper management of food grease
in attempt to minimize the discharge of grease into DFW’s sanitary sewer collection
system. The quantity of materials distributed as well as the audience profile will
be documented with EAD’s outreach programs.
• DFW Airport will conduct routine inspections at the DPS 4 K-9 facility to ensure
adequate BMPs are being employed to reduce the discharge of bacteria into the
stormwater collection system.
• The Airport will continue to participate in relevant NCTCOG Stormwater
Subcommittees to remain apprised of the water quality conditions for the Greater
Trinity River Region and the various programs or projects that can be considered
to improve conditions.
• Since 2015, DFW Airport has partnered with the TRA and the TCEQ through active
participation in the Texas Clean Rivers Program. As a member of the program,
DFW Airport must routinely monitor and sample various receiving waters
traversing through airport property. Routine analysis of an assortment of water
quality parameters acts as another mechanism to protect receiving waters by
promptly identifying water quality concerns, while enhancing the region’s water
quality monitoring network.
-
15
4.2 Endangered Species
The MS4 Permit prohibits discharges that would adversely affect listed endangered or
threatened species or their critical habitat. DFW Airport is not aware of allowable non-
stormwater discharges or stormwater discharges authorized per this permit that would
adversely affect such species. Furthermore, DFW Airport performs a Protected Species
Habitat assessment to ensure endangered or threatened species are not being
adversely impacted during any Airport development project as part of the National
Environmental Policy Act (NEPA) process.
-
16
5.0 PERMIT AUTHORIZATION AND SWMP
In accordance with TPDES General Permit No. TXR040000, the SWMP represents a
comprehensive 5-year program intended to manage the quality of stormwater discharges from
the MS4 into receiving waters of the U.S. The SWMP is developed and implemented in a manner
which prevents and/or reduces pollution in stormwater discharges to the MEP, effectively prohibits
illicit discharges to the storm system, protects water quality, and satisfies the appropriate water
quality requirements of the CWA and TWC. A completed Notice of Intent (NOI) is provided in
Section 2.0.
5.1 Permit Application
The NOI has been completed on a form approved by the TCEQ’s Executive Director and
contains the operator and site information. In addition, an application fee of $400 will be
submitted with the completed NOI and SWMP. Following permit issuance, an annual $100
Water Quality fee will additionally be paid by DFW Airport.
Following written instructions from the TCEQ’s Office of Chief Clerk, DFW Airport will
publish the Executive Director’s preliminary decision on the submitted NOI and SWMP in
the newspapers of largest circulation in Dallas and Tarrant counties in order to provide an
opportunity for public comment. Additionally, copies of the general permit and fact sheet,
the completed NOI, and the SWMP must be made available in a public location so that
the information may be viewed by interested parties. The public comment period will last
30 days from the date of notice publication; however, if a public meeting is requested, the
comment period will end at the close of the public meeting. The Executive Director will
make a final decision on permit approval subsequent to the public comment period.
5.2 SWMP and Applicable Minimum Control Measures
DFW Airport is considered a Level 2 non-traditional small MS4, and is required to develop
an effective stormwater management program addressing the following five minimum
control measures (MCMs):
1. Public Education, Outreach, and Involvement
-
17
2. Illicit Discharge Detection and Elimination
3. Construction Site Stormwater Runoff Control
4. Post Construction Stormwater Management in New Development and Re-
development
5. Pollution Prevention and Good Housekeeping for Municipal Operations
MCM No. 6, Industrial Stormwater Sources, is only applicable to Level 4 MS4 operators;
therefore, DFW Airport is not subject to this permit requirement. Additionally, the permit
allows for the incorporation of a seventh MCM, Authorization for Municipal Construction
Activities. This MCM provides an opportunity for stormwater construction discharges to
be authorized under the MS4 permit as opposed to obtaining a separate stormwater
construction general permit for each individual construction project (where permit
coverage is required). DFW Airport will not incorporate the 7th optional MCM in to the
SWMP, and, will continue to obtain separate stormwater construction permits for all
construction activities subject to permitting requirements.
According to the general permit, existing programs or best management practices (BMPs)
may be utilized to satisfy the permit requirements. DFW Airport currently maintains a
Stormwater Pollution Prevention Plan (SWP3). Many key BMPs and good housekeeping
practices outlined in the SWP3 will also be incorporated into the SWMP (included in
Appendix B).
-
18
6.0 DFW AIRPORT MINIMUM CONTROL MEASURES
The following programs or projects will be enacted throughout the five-year permit term as
described in the following subsections and will address the following MCMs:
▪ Public Education, Outreach, and Involvement
▪ Illicit Discharge Detection and Elimination
▪ Construction Site Stormwater Runoff Control
▪ Post Construction Stormwater Management in New Development and Re-
development
▪ Pollution Prevention and Good Housekeeping for Municipal Operations
6.1 MCM #1 Public Education, Outreach, and Involvement
A comprehensive Public Education, Outreach, and Involvement program will continue to
be implemented throughout the term of the permit to ensure target audiences are
educated about the consequences of stormwater pollution as it relates to the air
transportation industry, construction activities, commercial industries, and general
activities contributing to point and non-point source pollution. The Public Education,

II. New Outfall Characterization and Dry Weather Screening Program Responsible Department EAD
Target Audience Board Employees, Tenants, Contractors, Project Description DFW Airport Environmental Affairs Department (EAD) has characterized over 100 stormwater outfalls located on Airport property. The objective of this characterization was to assess both the physical condition of the stormwater infrastructure and the quality of water discharging from the outfall into the downstream waterbody. For the past five years, EAD has collected data on the physical characteristics of the water (for outfalls with dry weather discharges), including field and analytical data. The collected data have been used to identify potential illicit discharges and establish baseline values. These values enable staff the ability to recognize variances or when upstream conditions may be negatively impacting water quality. Due to the extensive nature of data collected and the establishment of effective baselines, EAD has decided to focus ongoing characterizations on newly created stormwater outfalls as well as verifying that dry weather discharges from existing outfalls occur within baselines. Dry weather screening will be conducted only for those outfalls supporting sensitive areas where stormwater runoff is discharged from selected industrial or commercial facilities.

6.3 MCM # 3 Construction Site Runoff Control DFW’s construction activities are closely monitored by the Design and Construction team
through implementation of a Construction Application (CA) process. The goal of the CA
process is to minimize the environmental impacts from construction activities including the
reduction of sediment, suspended materials, and other pollutants discharging into the
MS4. To ensure this goal is met, the EAD reviews construction design plans for potential
water quality impacts prior to issuing a building permit, and ensures all projects disturbing
1 acre or greater prepare a Stormwater Pollution Prevention Plan (SWPPP) in accordance
with TXR150000. EAD staff review construction SWPPPs and utilize a SWPPP checklist
to identify the requirements listed in the TXR150000 permit. The reviewer requires all
SWPPPs to:
• Utilize BMPs for erosion and sediment control
• Identify procedures for initiating and completing stabilization
• Identify BMPs for vehicle washing and other wash waters
• Identify BMPs for managing stormwater runoff from building materials
• Identify BMPs for construction waste, sanitary waste, and other materials
• Identify BMPs for spills and leaks
• Prohibit discharges not covered under the TXR150000 permit such as soaps,
solvents, fuels, and oils
After reviewing the design plans and SWPPP, an Environmental Compliance Inspector is
assigned to the project. The compliance inspector conducts routine site visits and reviews
documentation to confirm the project adheres to the requirements in their SWPPP. The
inspector confirms that BMPs are followed for vehicle washing, material management, and
waste management; erosion and sediment controls are properly installed and maintained;
stabilization is initiated; and no illicit discharges have occurred. Any non-compliances are
noted in the inspection report and communicated to all stakeholders.
Over the next five years, pollutants associated with construction activities will be mitigated
by incorporating the following MCMs verifying adequate use of stormwater controls during
design review, utilizing more effective BMPs, and developing an education and training
program.

Target Audience Board Employees, Tenants Project Description DFW Airport currently implements a Stormwater Pollution Prevention Plan (SWP3) to satisfy requirements of the Texas Pollutant Discharge Elimination System (TPDES) Multi-Sector General Permit (MSGP) for industrial operations. As a requirement of the SWP3, DFW Airport board employees and shared SWP3 participants are required to implement best management practices (BMPs) as outlined in the DFW Airport’s BMP Guidance Document. This is a working document specific to operations conducted at the Airport and is updated as needed to reflect preventative measures necessitated by activities with the potential to affect stormwater runoff. Inspected areas include all board owned and operated equipment storage and maintenance facilities, fuel storage facilities, hazardous waste yards, material storage areas, buildings, pavements and grounds, vehicle storage and maintenance yards, central utilities plants, solid waste facilities, common areas, and public terminal where pet waste disposal areas are located.
