Storm Water Management Plan
1.0 INTRODUCTION
The U.S Environmental Protection Agency (EPA) issued regulations in 1999 to protect storm
water quality in small cities and urbanized areas. In Texas, the Texas Commission on
Environmental Quality (TCEQ) was delegated the responsibility for implementing the regulations,
commonly called the Phase II Storm Water Program. The City of The Colony is one of several
hundred cities, counties, and other public entities required to develop a program to protect storm
water quality under Phase II regulations.
The EPA required the TCEQ to develop permit conditions for the Texas Pollutant Discharge
Elimination System (TPDES) General Permit Number TXR040000 by December 9, 2002 to
regulate public entities such as the City. The TCEQ finalized the permit August 13, 2007. With
the permit requirements finalized, the City is required to develop and submit to the TCEQ a plan
for a Storm Water Quality Management Program by February 11, 2008. The program will then
need to be implemented over the next five years.
The City has developed this Storm Water Management Plan (SWMP) to comply with the
requirements of the Texas Pollutant Discharge Elimination System (TPDES) General Permit No.
TXR040000. The SWMP includes best management practices (BMPs) that will be implemented
by the City to reduce storm water pollution to the "maximum extent practicable," as regulations
require.
Existing City storm water programs and activities that protect the City's storm water quality were
identified and are included in the SWMP. They will be supplemented with several new BMPs to
provide even more protection of storm water quality.
A schedule to implement the Storm Water Management Program, as well as measurable goals
to track the implementation progress, has been developed for each of the BMPs in this SWMP.
Each BMP was selected based on the projected effectiveness in protecting storm water quality
and its ability to aid in compliance with permit conditions.
The implementation schedule and measurable goals for the first five-year permit term were
selected so that the storm water program will be steadily phased in over the permit term. The
City will review the implementation progress each year and modify the Storm Water Management
Program as necessary. Annual updates will be provided to the TCEQ.
1.1 The City of The Colony
The City of The Colony, Texas is located in southeastern Denton County in North Central Texas.
It is east of Lake Lewisville and north of the City of Carrollton. The City limits encompass 13.7
square miles, with a population density of 2,783 people per square mile. According to the 2000
census, the population of the City is 26,531. The City is within the Texas Blackland Prairies
ecoregion, specifically the Northern Blackland Prairie. This ecoregion is characterized by fine
textured, clayey soils, and prairie vegetation. The area is characterized by a humid, subtropical,
continental climate with hot summers and mild winters. The average maximum temperature
occurs in July (96.3 degrees F); the average minimum temperature occurs in January (34.2
degrees F) with an annual average temperature of 65.7 degrees F. Rainfall is distributed
throughout the year, reaching a slight peak in spring. Snowfall is infrequent. Prevailing winds in
the area are from the south.

1.2 Water Quality
1.2.1 Storm Water and Water Quality in Texas
Storm water affects the quality of water in urban lakes, rivers, neighborhood creeks, and storm
drains. These drainage ways, both natural and man-made, effectively remove storm water runoff
from urban areas. In North Texas, storm drain systems are separate from sewage systems, and
typically untreated storm water runoff flows directly to the nearest bodies of water. Any pollutants
such as pesticides, oil, detergents, and bacteria that are present on urban land, streets, or other
surfaces are also carried along.
In order to protect water quality, it is necessary to identify the types and sources of pollution and
implement plans to protect the city's water resources. Historically, waters have been protected
through State and Federal regulation of "point-sources" or end-of-pipe sources of pollution. Over
time, it has become more evident that non-point sources of pollution, such as urban storm water
runoff, can create problems in water ways and impact the community's quality of life.
The Texas Commission on Environmental Quality (TCEQ) is charged through federal mandate
with protecting the quality of waters within the State. The TCEQ's approach to this mandate
includes measuring water quality at locations across the state, determining if the quality in
streams, lakes, and creeks is acceptable, and implementing plans to clean up water bodies that
are negatively impacted.
The Texas Surface Water Quality Standards are rules designed to establish goals for water
quality throughout the state, and provide a basis for regulatory programs to attain those goals.
Water quality standards serve to signal a situation where water quality may be inadequate to
meet the use or uses of a particular water body. Four general categories for water use are
defined in Texas: aquatic life use, contact recreation, public water supply, and fish consumption.
These are known as "designated uses." Most streams in the State have been classified with
designated uses but many smaller, intermittent streams have not been classified and do not have
associated designated uses.
Because it would be cost-prohibitive to test every water body for every possible pollutant,
assessments of water quality in Texas are performed by evaluating indicators of water quality.
Indicators are an indirect measure of the health or quality of a particular part of the aquatic
system. Some indicators, such as the health of fish communities, are tied to specific designated
uses, while others such as nutrients are not. Some of the most common indicators used by
TCEQ to determine the quality of water bodies include bacteria, dissolved oxygen, dissolved
solids, metals, and organic substances.
If the indicator data published in the Texas Water Quality Inventory (305(b) report) reveal that
water quality is inadequate to meet the goals of the water body's designated use, the TCEQ puts
the water body on the State's 303(d) list. This list is required by the federal Clean Water Act and
is submitted to EPA for approval. Water bodies put on the list are subject to a Total Maximum
Daily Load (TMDL) assessment. The TMDL is an intensive assessment of the root cause of poor
water quality and serves as the basis for development of a plan by local stakeholders to
remediate pollution sources.
1.2.2 Water Quality in The Colony Area
The major water body receiving urban storm water runoff from The Colony is Lewisville Lake
(Segment 0823 of the Trinity River), although portions of the City that are located in the Office
Creek and Indian Creek watersheds discharge runoff into the Elm Fork Trinity River below
Lewisville Lake (Segment (0822). Additionally, there are unnamed tributaries within the city that
receive storm water runoff. The designated uses for Lewisville Lake and the Elm Fork Trinity

Storm Water Management Plan
below Lewisville Lake are General, Contact Recreation, Aquatic Life, Fish Consumption, and
Public Water Supply.
The TCEQ 303(d) list identifies water bodies in Texas with known water quality impairments.
The stream segment of the Elm Fork Trinity below Lewisville Lake is included on the TCEQ Draft
2006 303(d) List for a water quality impairment due to elevated concentrations of bacteria,
specifically e.coli. Concern for elevated concentrations of nutrients, as demonstrated by
chlorophyll-a concentrations, and low concentrations of dissolved oxygen in the stream segment
are also indicated in the Draft 2006 TCEQ Water Quality Inventory. The 303(d) list indicates that
additional data and information are scheduled to be collected by the TCEQ before a total
maximum daily load (TMDL) study would be conducted.
Lewisville Lake is not listed on the 303(d) list as an impaired water body, although data indicate
there is a water quality concern for nutrients and bacteria. Specifically, the Draft 2006 TCEQ
Texas Water Quality Inventory shows elevated concentrations of nitrate, orthophosphorus, total
phosphorus, fecal coliform, and ammonia in the Stewart Creek arm of the lake and nitrate in the
Little Elm Creek arm of the lake.
Water quality data for Stewart Creek, which discharges into Lewisville Lake from the City and
upstream of the City, show elevated concentrations of nitrate, orthophosphorus, and total
phosphorus. The City's wastewater treatment plant effluent discharges into Stewart Creek at or
near the confluence of the creek with the lake.
Data collected from streams upstream and downstream of Lewisville Lake indicate a variety of
potential water quality issues. Little Elm Creek, which discharges into Lewisville Lake, has
depressed dissolved oxygen concentrations and an impairment for bacteria, specifically fecal
coliform. The Draft 2006 Texas Index of Water Quality Impairments (June 27, 2007) shows Little
Elm Creek to be a water body that does not meet applicable water quality standards or is
threatened for one or more designated uses by one or more pollutants. The City does not
discharge into Little Elm Creek and is not expected to be directly affected by the creek's
impairment designation.
Table 1 lists water quality indicators that reveal actual or potential concerns with local water
quality in the vicinity of The Colony.

2.0 REGULATORY REQUIREMENTS
Under the requirements of the Clean Water Act, the EPA is required to protect the water quality
for natural waters throughout the country. The EPA established the National Pollutant Discharge
Elimination System (NPDES) program to identify sources of water pollution and work to reduce
or eliminate the pollutants from the waters of the U.S.
The EPA has delegated responsibility for the NPDES program in Texas to the TCEQ. In addition
to issuing discharge permits to "point sources," such as municipal wastewater treatment plants,
the TCEQ is also responsible for minimizing pollution from "non-point sources", such as storm
water runoff from construction sites, industrial facilities or municipal storm sewer systems.
The TCEQ has issued requirements for minimizing storm water pollution from construction sites
and industrial facilities through the issuance of general permits. Sites and facilities comply with
these requirements by developing and implementing site-specific storm water pollution
prevention plans.
To protect storm water quality from pollution entering municipal separate storm sewer systems
(MS4s) in highly populated areas such as The Colony, the TCEQ developed a general permit
with conditions for municipalities to follow. This SWMP has been developed to meet those
requirements.
2.1 Overview
The City is required to develop a SWMP that describes specific actions that will be taken over a
five-year period to reduce pollutants and protect the City's storm water quality. This SWMP also
sets measurable goals and provides a schedule for the implementation of BMPs over the next
five years.
Various BMPs must be developed for each of six required minimum control measures that are
expected to minimize or eliminate storm water pollutants discharged into the storm sewer system
and provide water quality protection for receiving water bodies. A general description of the six
required control measures is provided below. The specific requirements for each minimum
control measure are provided in Section 4.
2.1.1 Public Education and Outreach
The City is required to distribute educational materials and perform outreach to inform the public
about the impacts polluted storm water runoff discharges can have on water quality. The TCEQ
has identified several groups that must be specifically targeted, including residents, businesses,
visitors, commercial and industrial facilities, and public service employees.
2.1.2 Public Participation/Involvement
The City must provide opportunities for citizens to participate in the development and
implementation of the Storm Water Management Program. Proper advance notice of public
meetings must also be provided.
2.1.3 Illicit Discharge Detection and Elimination
A plan must be developed and implemented to detect and eliminate illicit discharges to the storm
sewer system. This includes developing a storm sewer system map and conducting periodic
inspections of the system. The inspections are intended and identify and eliminate illegal
dumping, sanitary system cross connections, dry weather discharges, and other illicit discharges.
The City must also educate the community about hazards associated with illegal discharges and

Storm Water Management Plan
improper disposal of waste. The City is required to have ordinance provisions in place that
prohibit the release of non-allowable non-storm water discharges to the storm sewer system.
2.1.4 Construction Site Runoff Control
The City must develop and implement an erosion and sediment control program for construction
activities within the City. Operators of construction sites that disturb one acre or more of land will
be required to submit erosion control plans to the City. The City is required to have a process in
place to review the plans, as well as provide an opportunity for the public to view and comment
on the plans.
Through the use of an ordinance, the City must prohibit unauthorized discharges from regulated
construction sites in the City. The City is required to have a program to inspect the construction
activities and enforce the erosion control ordinance requirements.
2.1.5 Post-Construction Runoff Control
The City must develop a program to minimize discharges of polluted or erosive post-construction
storm water runoff from new development and redeveloped areas. Like the illicit discharge
prohibition and construction runoff control requirements, this measure must be implemented with
an ordinance enforced by the City. The specific requirements would be specified in the storm
water ordinance and/or the storm water design manual.
2.1.6 Pollution Prevention/Good Housekeepina
The City must work to identify and minimize potential sources of storm water pollution from
municipal operations. Actions that will be required to be taken will include employee training,
maintenance of the storm water system, and other best management practices. The TCEQ has
specified a number of municipal operations that must specifically be addressed.
2.2 Permit Applicability And Coverage
The TPDES Phase II MS4 permit applies to operators of publicly-owned storm sewer systems in
urbanized areas in Texas. The U.S. Census Bureau defines the urbanized areas based on the
population density and total population for an area. The City, except for the far northeastern
portion, is located within the "Dallas/Fort Worth Metroplex" U.S. Census Urbanized Area. Figure
1 shows the current city limits of The Colony with respect to the 2000 Census urbanized area.
Only the urbanized area of the City is required to be included in the Phase II MS4 Storm Water
Management Program. Components of the SWMP may be voluntarily implemented by the City
within the non-urbanized areas of the City as well.

Waters of the United States - (from 40 CFR 9 122.2) Waters of the United States or waters of the
U.S. means:
(a) all waters which are currently used, were used in the past, or may be susceptible to
use in interstate or foreign commerce, including all waters which are subject to the
ebb and flow of the tide;
(b) all interstate waters, including interstate wetlands;
(c) all other waters such as intrastate lakes, rivers, streams (including intermittent
streams), mudflats, sandflats, wetlands, sloughs, prairie potholes, wet meadows,
playa lakes, or natural ponds that the use, degradation, or destruction of which would
affect or could affect interstate or foreign commerce including any such waters:
(1) which are or could be used by interstate or foreign travelers for recreational or
other purposes;
(2) from which fish or shellfish are or could be taken and sold in interstate or foreign
commerce; or
(3) which are used or could be used for industrial purposes by industries in
interstate commerce;
(d) all impoundments of waters otherwise defined as waters of the United States under
this definition;
(e) tributaries of waters identified in paragraphs (a) through (d) of this definition;
(f) the territorial sea; and
(g) wetlands adjacent to waters (other than waters that are themselves wetlands)
identified in paragraphs (a) through (f) of this definition.
Waste treatment systems, including treatment ponds or lagoons designed to meet the
requirements of CWA (other than cooling ponds as defined in 40 CFR 9 423.11 (m) which also
meet the criteria of this definition) are not waters of the United States. This exclusion applies only
to manmade bodies of water which neither were originally created in waters of the United States
(such as disposal area in wetlands) nor resulted from the impoundment of waters of the United
States. Waters of the United States do not include prior converted cropland. Notwithstanding the
determination of an area=s status as prior converted cropland by any other federal agency, for
the purposes of the Clean Water Act, the final authority regarding Clean Water Act jurisdiction
remains with EPA.

3.0 APPROACH
The City of The Colony (City) developed this SWMP to comply with TPDES requirements for
storm water discharges and certain non-storm water discharges. The SWMP is intended to aid in
the City's efforts to reduce storm water pollutants from the City's storm sewer system to the
maximum extent practicable as required by the TPDES General Permit.
The SWMP describes specific actions that will be taken over a five-year period to reduce
pollutants and protect the City's storm water quality. The specific activities to be implemented are
referred to as best management practices. Various BMPs have been developed for each of the
six "minimum control measures" required by the General Permit. The SWMP also sets
measurable goals and provides a schedule for the implementation of the BMPs. Implementation
of the selected BMPs is expected to result in reductions of pollutants discharged into The
Colony's streams, ponds, and lakes.
The Colony Engineering Services Department has been responsible for the overall development
of the SWMP, but most areas of the City's functions will have some degree of responsibility in the
implementation of the plan. As a result, input from each of the staff in the affected departments
has been obtained to develop this SWMP for the City.
3.1 Best Management Practice Selection Process
A two-step process was utilized to select the BMPs to be included in The Colony's SWMP. The
first step in selecting BMPs included an evaluation of existing practices. The second step
included meetings with staff from affected City departments to identify new BMPs. Various
structural and non-structural BMPs will be implemented throughout the five-year permit term
authorized under the General Permit.
3.1.1 Initial Assessment
The City of The Colony has historically implemented various BMPs intended to protect storm
water quality. An important aspect of developing an effective, compliant, and cost efficient SWMP
is to account for these existing programs. Details of the City's existing storm water-related
practices were identified and included as BMPs selected for this SWMP.
As shown in Section 4, the minimum control measure requirements met by each existing BMP
are noted. Some of the City's existing programs meet specific permit requirements, while others
serve as a foundation for the continued development of additional BMPs to meet the requirement
of reducing pollutants to the maximum extent practicable.
3.1.2 Identification of Additional BMPs
Additional BMPs were selected to supplement the City's existing programs and to satisfy unmet
requirements of the Phase II MS4 permit. The supplemental BMPs were evaluated based on
their ability to meet at least one, and preferably several, of the minimum control measure
requirements.
The evaluation process involved researching a variety of sources of BMPs, such as regulatory
agencies, industry associations, and private enterprises. Some of the additional BMPs were
selected directly from standard BMP "toolboxes" available from the EPA or the North Central
Texas Council of Governments (NCTCOG), while others were tailored to the specific needs of
The Colony. Each BMP considered was evaluated based on the following criteria:
· Which of the minimum control measure requirements does the BMP meet?
· How does the BMP fit into the City's existing goals, operations, and activities?

City of The Colony
Storm Water Management Plan
· What is the anticipated effectiveness of the BMP?
· What is the general cost range to implement the BMP?
Specific costs for the BMPs were not identified for the development of this plan; however BMPs
with significant investment requirements and relatively minor storm water quality benefit were not
selected. More detailed Budget requirements will be evaluated for each BMP in the first year of
the plan's implementation.
3.2 Selection Process for Measurable Goals and Implementation Schedule
Specific measurable goals have been developed for each BMP. In accordance with the permit
requirements, measurable goals have been developed to evaluate the success of the City's
SWMP toward reaching the goal of protecting water quality and reducing pollutants to the
maximum extent practicable. Goals were selected with a consideration toward achieving steady
implementation, assessing the ability to measure and track progress, and working within
budgetary constraints.
For the first five-year permit term, the TCEQ has authorized the steady implementation of the
SWMP over a five-year period. In general, measurable goals for existing BMPs monitor the
effectiveness of the BMP, whereas measurable goals for new BMPs monitor their
implementation progress.
During the first and second year of the permit program, the City's focus will be identifying the
specific effort and budgetary requirements of each of the BMPs. The second and third years are
for initial program implementations. The third through fifth years focus on evaluating the
effectiveness and tracking the implementation of the BMPs.
Implementation of the BMPs will begin in the second and third year and will continue until full
implementation is achieved in the fifth and final year of the initial permit term. Measurable goals
for each of the BMPs in the first permit term will focus on tracking the effectiveness of the
implementation and will transition in subsequent years to tracking the benefit of each BMP
toward achieving its intended goal, namely protecting water quality.

4.0 MINIMUM CONTROL MEASURE REQUIREMENTS
The EPA and the TCEQ have specified six types of "minimum control measures" (MCM) for
inclusion in each SWMP. Specific requirements have been developed by the TCEQ for each
control measure. The City has identified numerous existing and supplemental BMPs that will be
included in the SWMP. Additional discussion of the BMPs is provided in Appendix B of the
SWMP. Following are the regulatory requirements for each minimum control measure, as stated
in TXR040000.
"Part III. Storm Water Management Program (SWMP)
A. Minimum Control Measures
1. Public Education and Outreach on Storm Water Impacts
(a) A public education program must be developed and implemented to
distribute educational materials to the community or conduct equivalent
outreach activities that will be used to inform the public. The MS4
operator may determine the most appropriate sections of the population
at which to direct the program. The MS4 operator must consider the
following groups and the SWMP shall provide justification for any listed
group that is not included in the program:
(1 ) residents;
(2) visitors;
(3) public service employees;
( 4 ) busi nesses;
(5) commercial and industrial facilities; and
(6) construction site personnel.
The outreach must inform the public about the impacts that storm water
run-off can have on water quality, hazards associated with illegal
discharges and improper disposal of waste, and steps that they can take
to reduce pollutants in storm water runoff.
(b) The MS4 operator must document activities conducted and materials
used to fulfill this control measure. Documentation shall be detailed
enough to demonstrate the amount of resources used to address each
group. This documentation shall be retained in the annual reports
required in Part IV.B.2. of this general permit.
2. Public InvolvemenUParticipation
The MS4 operator must, at a minimum, comply with any state and local public
notice requirements when implementing a public involvement/participation
program. It is recommended that the program include provisions to allow all
members of the public within the City the opportunity to participate in SWMP
development and implementation.
3. Illicit Discharge Detection and Elimination
(a) Illicit Discharges
A section within the SWMP must be developed to establish a program to
detect and eliminate illicit discharges to the small MS4. The SWMP must
prepared bY Freese and NiChOlS, Inc.
page 13
TPDES General Permit
No. TXR040000
City of The Colony
Storm Water Management Plan
include the manner and process to be used to effectively prohibit illicit
discharges. To the extent allowable under state and local law, an
ordinance or other regulatory mechanism must be utilized to prohibit and
eliminate illicit discharges. Elements must include:
(1) Detection
The SWMP must list the techniques used for detecting illicit
discharges; and
(2) Elimination
The SWMP must include appropriate actions and, to the extent
allowable under state and local law, establish enforcement
procedures for removing the source of an illicit discharge.
(b) Allowable Non-Storm Water Discharges
Non-storm water flows listed in Part II.B and Part VI.B. do not need to be
considered by the MS4 operator as an illicit discharge requiring
elimination unless the operator of the small MS4 or the executive director
of the TCEQ identifies the flow as a significant source of pollutants to the
small MS4. In lieu of considering non-storm water sources on a case-by-
case basis, the MS4 operator may develop a list of common and
incidental non-storm water discharges that will not be addressed as illicit
discharges requiring elimination. If developed, the listed sources must not
be reasonably expected to be significant sources of pollutants either
because of the nature of the discharge or the conditions that are
established by the MS4 operator prior to accepting the discharge to the
small MS4. If this list is developed, then all local controls and conditions
established for these listed discharges must be described in the SWMP
and any changes to the SWMP must be included in the annual report
described in Part IV.B.2. of this general permit, and must meet the
requirements of Part II. D.3. of the general permit.
(c) Storm Sewer Map
(1) A map of the storm sewer system must be developed and must
include the following:
(i) the location of all outfalls;
(ii) the names and locations of all waters of the U.S. that receive
discharges from the outfalls; and
(iii) any additional information needed by the permittee to implement
its SWMP.
(2) The SWMP must include the source of information used to develop
the storm sewer map, including how the outfalls are verified and how
the map will be regularly updated.

4. Construction Site Storm Water Runoff Control
The MS4 operator, to the extent allowable under State and local law, must
develop, implement, and enforce a program to reduce pollutants in any storm
water runoff to the small MS4 from construction activities that result in a land
disturbance of greater than or equal to one acre or if that construction activity
is part of a larger common plan of development or sale that would disturb one
acre or more of land. The MS4 operator is not required to develop, implement,
and/or enforce a program to reduce pollutant discharges from sites where the
construction site operator has obtained a waiver from permit requirements
under NPDES or TPDES construction permitting requirements based on a low
potential for erosion.
(a) The program must include the development and implementation of, at a
minimum, an ordinance or other regulatory mechanism to require erosion
and sediment controls, as well as sanctions to ensure compliance, to the
extent allowable under state and local law.
(b) Requirements for construction site contractors to, at a minimum:
(1) implement appropriate erosion and sediment control BMPs; and
(2) control waste such as discarded building materials, concrete truck
washout water, chemicals, litter, and sanitary waste at the
construction site that may cause adverse impacts to water quality.
(c) The MS4 operator must develop procedures for:
(1) site plan review which incorporate consideration of potential water
quality impacts;
(2) receipt and consideration of information submitted by the public; and
(3) site inspection and enforcement of control measures to the extent
allowable understate and local law.
5. Post-Construction Storm Water Management in New and Redevelopment
To the extent allowable under state and local law, the MS4 operator must
develop, implement, and enforce a program to address storm water runoff
from new development and redevelopment projects that disturb greater than
or equal to one acre of land, including projects less than one acre that are part
of a larger common plan of development or sale that will result in disturbance
of one or more acres, that discharge into the small MS4. The program must
ensure that controls are in place that would prevent or minimize water quality
impacts. The permittee shall:
(a) Develop and implement strategies which include a combination of
structural and/or non-structural BMPs appropriate for the community;
(b) Use an ordinance or other regulatory mechanism to address post-
construction runoff from new development and redevelopment projects to
the extent allowable under state and local law; and
(c) Ensure adequate long-term operation and maintenance of BMPs.

6. Pollution Prevention/Good Housekeeping for Municipal Operations
A section within the SWMP must be developed to establish an operation and
maintenance program, including an employee training component, that has
the ultimate goal of preventing or reducing pollutant runoff from municipal
operations.
(a) Good Housekeeping and Best Management Practices (BMPs)
Housekeeping measures and BMPs (which may include new or existing
structural or non-structural controls) must be identified and either
continued or implemented with the goal of preventing or reducing pollutant
runoff from municipal operations. Examples of municipal operations and
municipally owned areas include, but are not limited to:
(1) park and open space maintenance;
(2) street, road, or highway maintenance;
(3) fleet and building maintenance;
(4) storm water system maintenance;
(5) new construction and land disturbances;
(6) municipal parking lots;
(7) vehicle and equipment maintenance and storage yards;
(8) waste transfer stations; and
(9) salt/sand storage locations.
(b) Training
A training program must be developed for all employees responsible for
municipal operations subject to the pollution prevention/good
housekeeping program. The training program must include training
materials directed at preventing and reducing storm water pollution from
municipal operations. Materials may be developed, or obtained from the
EPA, states, or other organizations and sources. Examples or descriptions
of training materials being used must be included in the SWMP.
(c) Structural Control Maintenance
If BMPs include structural controls, maintenance of the controls must be
performed at a frequency determined by the MS4 operator and consistent
with maintaining the effectiveness of the BMP. The SWMP must list all of
the followi ng :
(1) maintenance activities;
(2) maintenance schedules; and
(3) long-term inspection procedures for controls used to reduce floatables
and other pollutants.
(d) Disposal of Waste
Waste removed from the small MS4 and waste that is collected as a result
of maintenance of storm water structural controls must be properly

disposed. A section within the SWMP must be developed to include
procedures for the proper disposal of waste, including:
(1) dredge spoil;
(2) accumulated sediments; and
(3) floatables.
(e) Municipal Operations and I ndustrial Activities
The SWMP must include a list of all:
(1) municipal operations that are subject to the operation, maintenance,
or training program developed under the conditions of this section;

5.0 BMPS, MEASURABLE GOALS, AND IMPLEMENTATION SCHEDULE
In accordance with TCEQ's General Permit requirements, The Colony's SWMP specifies existing
and planned BMPs to protect storm water quality within the City as it reaches creeks, rivers and
lakes. An implementation plan has been developed to show the City's planned schedule for
expanding the scope of existing BMPs or developing and implementing new BMPs. Methods and
measures to track the success of the implementation of the program have been developed for
each BMP.
As noted in Section 3.0, the TCEQ requires BMPs to be implemented to meet six required
minimum control measures, and a seventh measure can be included at the option of the City.
The BMPs identified in this SWMP for each of the minimum control measures generally fall into
one of the following types:
· Public education and involvement activities
· Coordination between the City, the citizens, businesses, and public entities
· Ordinances
· Inspections
· Monitoring
· Enforcement
· Plan reviews
. Training
· Maintenance activities
· Structural controls
Appendix A contains a list of each BMP selected for inclusion in the City's SWMP. A description
of each BMP is provided, along with an implementation schedule with associated measurable
goals over the next five years. For existing BMPs, measurable goals will be based on the
effectiveness of the protective measure. Measurable goals tracking the implementation progress
of each new BMP are shown for protective measures not already in place.

6.0 MEASURABLE GOAL EVALUATION PROCESS
The selected measurable goals for each BMP will be evaluated on an annual basis.
Implementation of each BMP will be tracked as appropriate during each permit year in order to
provide documentation of the BMP activities. Relative success at achieving the measurable
goals, as well as an assessment of the effectiveness of each BMP, will also be evaluated on an
annual basis.
Multiple City departments will be responsible for implementing portions of the SWMP and for
tracking and evaluating the City's success in meeting the plan's measurable goals. Each City
department with activities or responsibilities that may impact storm water quality will provide to
the Storm Water Coordinator documentation showing progress towards meeting the annual
measurable goals for each BMP.

7.0 ASSESSMENT OF NON-STORM WATER DISCHARGES
In accordance with the requirements of the Phase II MS4 permit, the following non-storm water
discharges were assessed in order to determine whether they are known to be significant
contributors of pollutants to the City's water bodies:
(a) water line flushing (excluding discharges of hyperchlorinated water, unless the water is
first dechlorinated and discharges are not expected to adversely affect aquatic life);
(b) runoff or return flow from landscape irrigation, lawn irrigation, and other irrigation utilizing
potable water, groundwater, or surface water sources;
(c) discharges from potable water sources;
(d) diverted stream flows;
(e) rising ground waters and springs;
(f) uncontaminated ground water infiltration;
(g) uncontaminated pumped ground water;
(h) foundation and footing drains;
(i) air conditioning condensate;
0) water from crawl space pumps;
(k) individual residential vehicle washing;
(I) flows from wetlands and riparian areas;
(m) dechlorinated swimming pool discharges;
(n) street wash water;
(0) discharges or flows from fire fighting activities (fire fighting activities do not include
washing of trucks, run-off water from training activities, test water from fire suppression
system, and similar activities);
(p) other allowable non-storm water discharges listed in 40 CFR 9 122.26( d)(2)(iv)(B)( 1);
(q) non-storm water discharges that are specifically listed in the TPDES Multi Sector
General Permit (MSGP) or the TPDES Construction General Permit (CGP); and
(r) other similar occasional incidental non-storm water discharges, unless the TCEQ
develops permits or regulations addressing these discharges.
Non-storm water discharges from the list above were evaluated by the City to determine if any
known, significant, water quality impacts were created as a result of the discharges. There is no
knowledge of adverse impacts to the City's water quality from any of the listed discharges.

8.0 RECORDKEEPING AND REPORTING
8.1 Recordkeeping
The City will maintain all records, a copy of the TPDES general permit and all data used to
complete the Notice of Intent (NOI) for this permit, for a period of at least three years, or for the
term of this permit, whichever is longer. A current, up-to-date copy of the SWMP and a copy of
the general permit requirements will be maintained at City Hall.
The City will make the compiled records, including the NOI and SWMP, available for public
viewing at City Hall. The SWMP will be available for viewing during normal office hours, and
available supporting documents will be able to be viewed within ten working days following the
request from the public. Other records will be provided within 10 working days, unless the
request requires an unusual amount of time or effort to assemble. In such a case, Texas law
regarding the Public Information Act will be followed. Reasonable charges, in accordance with
Texas law, may be levied by the City for researching and preparing any requested materials.
8.2 Annual Report
The City will submit an annual update report to the Executive Director of the TCEQ by the
reporting deadline each year of the permit term. The City will maintain copies of the annual
reports at City Hall.
The annual report will address the requirements listed in the TPDES Phase II MS4 general
permit rules. Generally, the update report will document the storm water-related activities for the
previous year, evaluate the success of each BMP relative to their measurable goals, and discuss
plans for the upcoming year, including modifications to the SWMP. Modifications may include
replacement of previously selected BMPs, alteration of the implementation schedule, or other
changes allowed by the permit.
8.3 Plan Updates
This plan may be updated by the City at any time. When considering eliminating a BMP, it is
necessary to review the information in Appendix B to determine if the removal of the BMP will
result in non-compliance for any of the minimum control measures. This would occur if the BMP
is the only BMP that provides compliance for a specific permit provision. In such a case, the BMP
would need to be replaced with a new BMP that continues to meet the relevant permit
requirement.
Documentation of plan updates involving changes in BMPs, measurable goals, or the
implementation schedule are maintained in Appendix H.
8.4 Reference Material
Several sources of information are available for use in the maintenance and update of the
SWMP. Each of these resources are recommended for additional information about alternative
BMP options.
The North Central Texas Council of Governments (NCTCOG) has developed a Construction
BMP Manual, which is available to NCTCOG member cities and can be found on the Internet at
www.dfwstormwater.com .
The U.S. EPA has developed an electronic Storm Water Management BMP Toolbox specifically
for use by Phase II MS4 regulated entities. It contains a list of BMPs for each minimum control
measure.

9.0 STORM WATER PERMITS FOR CITY-OWNED FACILITIES
Site-specific Storm Water Management Programs are required to be developed, implemented
and maintained for certain types of facilities specifically designated in the federal and state storm
water regulations. Examples of facilities subject to these permit requirements include automobile
salvage yards, chemical production plants, paper and pulp mills, and many other industrial
facilities.
Municipalities often operate several types of facilities that are subject to the industrial storm water
permitting requirements. Landfills, wastewater treatment plants, vehicle maintenance facilities,
municipal airports, and print shops are examples of regulated industrial facilities commonly
operated by municipalities.
The City is required to document in this plan each City-owned or operated facility with a TPDES
multi-sector general permit. A copy of each facility's permit authorization is located in Appendix F
of this plan for reference.

Illicit Discharge Detection and Elimination System
Requirements
(a) Illicit Discharges
A section within the SWMP must be developed to
establish a program to detect and eliminate illicit
discharges to the small MS4. The SWMP must
include the manner and process to be used to
effectively prohibit illicit discharges. To the extent
allowable under state and local law, an ordinance or
other regulatory mechanism must be utilized to
prohibit and eliminate illicit discharges. Elements
must include:
(1) Detection
The SWMP must list the techniques used for
detecting illicit discharges.
(2) Elimination
The SWMP must include appropriate actions
and, to the extent allowable under state and local
law, establish enforcement procedures for
removing the source of an illicit discharge.
(b) Allowable Non-Storm Water Discharges
Non-storm water flows listed in Part II. B and Part
VI.B. do not need to be considered by the MS4
operator as an illicit discharge requiring elimination
unless the operator of the small MS4 or the executive
director identifies the flow as a significant source of
pollutants to the small MS4. In lieu of considering
non-storm water sources on a case-by-case basis,
the MS4 operator may develop a list of common and
incidental non-storm water discharges that will not be
addressed as illicit discharges requiring elimination. If
developed, the listed sources must not be reasonably
expected to be significant sources of pollutants either
because of the nature of the discharge or the
conditions that are established by the MS4 operator
prior to accepting the discharge to the small MS4. If
this list is developed, then all local controls and
conditions established for these listed discharges
must be described in the SWMP and any changes to
the SWMP must be included in the annual report
described in Part IV.B.2. of this general permit, and
must meet the requirements of Part II.D.3. of the
general perm it.

(ii) the names and locations of all waters of
the U.S. that receive discharges from the
outfalls; and
17 Storm Sewer System Map
(iii) any additional information needed by the
permittee to implement its SWMP.
(2) The SWMP must include the source of
information used to develop the storm sewer
map, including how the outfalls were verified and
how the map will be regularly updated.

Construction Site Runoff Control Requirements
The MS4 operator, to the extent allowable under State
and local law, must develop, implement, and enforce a
program to reduce pollutants in any storm water runoff to
the small MS4 from construction activities that result in a
land disturbance of greater than or equal to one acre or if
that construction activity is part of a larger common plan
of development or sale that would disturb one acre or
more of land. The MS4 operator is not required to
develop, implement, and/or enforce a program to reduce
pollutant discharges from sites where the construction
site operator has obtained a waiver from permit
requirements under NPDES or TPDES construction
permitting requirements based on a low potential for
erosion.
(a) The program must include the development and
implementation of, at a minimum, an ordinance or
other regulatory mechanism to require erosion and
sediment controls, as well as sanctions to ensure
compliance, to the extent allowable under State and
local law.
(b) Requirements for construction site contractors to, at a
minimum:
(1) implement appropriate erosion and sediment
control best management practices; and
(2) control waste such as discarded building
materials, concrete truck washout water,
chemicals, litter, and sanitary waste at the
construction site that may cause adverse impacts
to water quality;
(c) The MS4 operator must develop procedures for:
(1) site plan review which incorporate consideration
of potential water quality impacts;
(2) receipt and consideration of information
submitted by the public; and
(3) site inspection and enforcement of control
measures to the extent allowable under state and
local law.

Post-Construction Site Runoff Control Requirements
To the extent allowable under state and local law, the
MS4 operator must develop, implement, and enforce a
program to address storm water runoff from new
development and redevelopment projects that disturb
greater than or equal to one acre of land, including
projects less than one acre that are part of a larger
common plan of development or sale that will result in
disturbance of one or more acres, that discharge into the
small MS4. The program must ensure that controls are in
place that would prevent or minimize water quality
impacts. The permittee shall:
(a) Develop and implement strategies which include a
combination of structural and/or non-structural BMPs
appropriate for your community;
(b) Use an ordinance or other regulatory mechanism to
address post-construction runoff from new
development and redevelopment projects to the
extent allowable under state and local law; and

Part II. Permit Applicability and Coverage
This general permit provides authorization for storm water and certain non-storm water discharges from small
municipal separate storm sewer systems (MS4) to surface water in the state. The general permit contains
requirements applicable to all small MS4s that are eligible for coverage under this general permit.
A. Small MS4s Eligible for Authorization by General Permit
1. Small MS4s Located in an Urbanized Area
A small MS4 that is fully or partially located within an urbanized area, as determined by the
2000 Decennial Census by the U.S. Bureau of Census, must obtain authorization for the
discharge of storm water runoff and is eligible for coverage under this general permit.
2. Designated Small MS4s
A small MS4 that is outside an urbanized area that is "designated" by TCEQ based on
evaluation criteria as required by 40 CFR 9 122.32(a)(2) or 40 CFR 9 122.26(a)(I)(v) and
adopted by reference in Title 30, Texas Administrative Code (T AC), 9 281.25, is eligible for
coverage under this general permit. Following designation, operators of small MS4s must
obtain authorization under this general permit or apply for coverage under an individual
TPDES storm water permit within 180 days of notification of their designation.
The portion of the small MS4 that is required to meet the conditions of this general permit are those
portions that are located within the urbanized area, as well as any portion of the small MS4 that is
designated.
B. Allowable Non-Storm Water Discharges
The following non-storm water sources may be discharged from the small MS4 and are not required
to be addressed in the small MS4's Illicit Discharge and Detection or other minimum control
measures, unless they are determined by the permittee or the TCEQ to be significant contributors of
pollutants to the small MS4:
Page 9
TPDES General Permit No. TXR040000
1. water line flushing (excluding discharges of hyper chlorinated water, unless the water is first
dechlorinated and discharges are not expected to adversely affect aquatic life);
2. runoff or return flow from landscape irrigation, lawn irrigation, and other irrigation utilizing
potable water, groundwater, or surface water sources;
3. discharges from potable water sources;
4. diverted stream flows;
5. rising ground waters and springs;
6. uncontaminated ground water infiltration;
7 . uncontaminated pumped ground water;
8. foundation and footing drains;
9. air conditioning condensation;
10. water from crawl space pumps;
11. individual residential vehicle washing;
12. flows from wetlands and riparian habitats;
13. dechlorinated swimming pool discharges;
14. street wash water;
15. discharges or flows from fire fighting activities (fire fighting activities do not include
washing of trucks, run-off water from training activities, test water from fire suppression

TPDES General Permit No. TXR040000
C. Limitations on Permit Coverage
1. Discharges Authorized by Another TPDES Permit
Discharges authorized by an individual or other general TPDES permit may be authorized
under this TPDES general permit only if the following conditions are met:
(a) the discharges meet the applicability and eligibility requirements for coverage under
this general permit;
(b) a previous application or permit for the discharges has not been denied, terminated,
or revoked by the executive director as a result of enforcement or water quality
related concerns. The executive director may provide a waiver to this provision
based on new circumstances at the regulated small MS4; and
( c ) the executive director has not determined that continued coverage under an
individual permit is required based on consideration of an approved total maximum
daily loading (TMDL) model and implementation plan, anti-backsliding policy,
history of substantive non-compliance or other 30 T AC Chapter 205 considerations
and requirements, or other site-specific considerations.
2. Discharges of Storm Water Mixed with Non-Storm Water
Storm water discharges that combine with sources of non-storm water are not eligible for
coverage by this general permit, unless either the non-storm water source is described in Part
II.B or Part VI.B. of this general permit or the non-storm water source is authorized under a
separate TPDES permit.
3. Compliance with Water Quality Standards
Discharges to surface water in the state that would cause or contribute to a violation of water
quality standards or that would fail to protect and maintain existing designated uses are not
eligible for coverage under this general permit. The executive director may require an
application for an individual permit or alternative general permit to authorize discharges to
surface water in the state if the executive director determines that an activity will cause a
violation of water quality standards or is found to cause or contribute to the impairment of a
designated use of surface water in the state. The executive director may also require an
application for an individual permit considering factors described in Part II.E.2.
4. Discharges to Water Quality-Impaired Receiving Waters
New sources or new discharges of the constituent(s) of concern to impaired waters are not
authorized by this permit unless otherwise allowable under 30 TAC Chapter 305 and
applicable state law. Impaired waters are those that do not meet applicable water quality
standard( s) and are listed on the Clean Water Act 9 303 (d) list. Constituents of concern are
those for which the water body is listed as impaired.
Page 11
TPDES General Permit No. TXR040000
Discharges of the constituent( s) of concern to impaired water bodies for which there is a
TMDL implementation plan are not eligible for this general permit unless they are consistent
with the approved TMDL and the implementation plan. Permitted MS4 operators must
incorporate the limitations, conditions and requirements applicable to their discharges,
including monitoring frequency and reporting required by TCEQ rules, into their SWMP in
order to be eligible for permit coverage. F or discharges not eligible for coverage under this
general permit, the discharger must apply for and receive an individual TPDES permit prior
to discharging.
5 . Discharges to the Edwards Aquifer Recharge Zone
Discharges of storm water from regulated small MS4s, and other non-storm water
discharges, can not be authorized by this general permit where those discharges are
prohibited by 30 TAC Chapter 213 (relating to Edwards Aquifer). New discharges located
within the Edwards Aquifer Recharge Zone, or within that area upstream from the recharge
zone and defined as the Contributing Zone, must meet all applicable requirements of, and
operate according to, 30 T AC Chapter 213 (Edwards Aquifer Rule) in addition to the
provisions and requirements of this general permit.
For existing discharges, the requirements of the agency-approved Water Pollution Abatement
Plan under the Edwards Aquifer Rules are in addition to the requirements of this general
permit. BMPs and maintenance schedules for structural storm water controls, for example,
may be required as a provision of the rule. All applicable requirements of the Edwards
Aquifer Rule for reductions of suspended solids in storm water runoff are in addition to the
effluent limitation requirements found in Part VI.D. of this general permit. A copy of the
agency-approved Water Pollution Abatement Plans that are required by the Edwards Aquifer
Rule must either be attached as a part of the SWMP or referenced in the SWMP. For
discharges located on or within ten stream miles upstream of the Edwards Aquifer recharge
zone, applicants must also submit a copy of the NOI to the appropriate TCEQ regional
office.

(relating to Watershed Protection) for water quality areas and watersheds.
7. Protection of Streams and Watersheds by Home Rule Municipalities
This general permit does not limit the authority of a home-rule municipality provided by S
401.002 of the Texas Local Government Code.
8. Indian Country Lands
Storm water runoff from MS4s or construction activities occurring on Indian Country lands
are not under the authority of the TCEQ and are not eligible for coverage under this general
permit. If discharges of storm water require authorization under federal NPDES regulations,
authority for these discharges must be obtained from the U.S. Environmental Protection
Agency (EPA).
9 . Other
Nothing in Part II of the general permit is intended to negate any person's ability to assert the
force majeure (act of God, war, strike, riot, or other catastrophe) defenses found in 30 TAC S
70.7.
This permit does not transfer liability for the act of discharging without, or in violation of, a
NPDES or a TPDES permit from the operator of the discharge to the permittee(s).
D. Obtaining Authorization
1. Application for Coverage
When submitting an NOI and Storm Water Management Program (SWMP) as described in
Parts II.D.3., II.D.4, and Part III for coverage under this general permit, the applicant must
follow the public notice and availability requirements found in Part II.D.12. of this section.
Applicants seeking authorization to discharge under this general permit must submit a
completed NOI, on a form approved by the executive director, and a SWMP as described in
Part III. The NOI and SWMP must be submitted to the TCEQ Water Quality Division, at the
address specified on the form. Discharge authorization begins when the applicant is notified
by TCEQ that the NOI and SWMP have been administratively and technically reviewed and
the applicant has followed the public participation provisions in Part II.D.12. Following
review of the NOI and SWMP, the executive director may determine that: 1) the submission
is complete and confirm coverage by providing a notification and an authorization number,
2) the NOI and/or SWMP are incomplete and deny coverage until a complete NOI and/or
SWMP are submitted, 3) approve the NOI and/or SWMP with revisions and provide a
written description of the required revisions along with any compliance schedule(s), or 4)

submitted with the NOI. The SWMP must include a time line that demonstrates a schedule
for implementation of the program throughout the permit term. The program must be
completely implemented within five years of the issuance date of this general permit, or
within five years of being designated for those small MS4s which are designated following
permit issuance. Implementation of the SWMP is required immediately following receipt of
written authorization from the TCEQ.
Changes may be made to the SWMP during the permit term. Changes that are made to the
SWMP before the NOI is approved by the TCEQ must be submitted in a letter providing
supplemental information to the NOI. Changes to the SWMP that are made after TCEQ
approval of the NOI and SWMP may be made following written approval of the changes
from the TCEQ, except that written approval is not required for the following changes:

publication of notice( s) within 60 days of receiving the written instructions from the
Office of Chief Clerk.
(i) The executive director, after considering public comment, shall approve, approve
with conditions, or deny the NOI based on whether the NOI and SWMP meet the
requirements of this general permit.
G) Persons whose names and addresses appear legibly on the sign in sheet from the
public meeting and persons who submitted written comments to the TCEQ will be
notified by the TCEQ's Office of Chief Clerk of the executive director's decision
regarding the authorization.
E. Permitting Options
1. Authorization Under the General Permit
An operator of a small MS4 is required to obtain authorization either under this general
permit, or under an individual TPDES permit if it is located in an urbanized area or if it is
designated by the TCEQ. Multiple small MS4s with separate operators must individually
submit an NOI to obtain coverage under this general permit, regardless of whether the
systems are physically interconnected, located in the same urbanized area, or are located in
the same watershed. Each regulated small MS4 will be issued a distinct permit number.
These MS4 operators may combine or share efforts in meeting any or all of the SWMP
requirements stated in Part III of this general permit. MS4 operators that share SWMP
development and implementation must meet the following conditions:
(a) Participants
The SWMP must clearly list the name and permit number for each MS4 operator
that contributes to development or implementation of the SWMP, and provide
confirmation that the contributing MS4 operator has agreed to contribute. If a
contributing MS4 has submitted an NOI and SWMP to TCEQ, but has not yet
Page 19
TPDES General Permit No. TXR040000
received written notification of approval, along with the accompanying permit
authorization number, a copy of the submitted NOI form must be made readily
available or included in the SWMP.
(b) Responsibilities
Each permittee is entirely responsible for meeting SWMP requirements within the
boundaries of its MS4. Where a separate MS4 operator is contributing to
implementation of the SWMP, the SWMP must clearly define the contribution and
clearly identify the contributing MS4 operator.
2. Alternative Coverage under an Individual TPDES Permit
An MS4 operator eligible for coverage under this general permit may alternatively be
authorized under an individual TPDES permit according to 30 T AC Chapter 305 (relating to
Consolidated Permits). The executive director may require an MS4 operator, authorized by
this general permit, to apply for an individual TPDES permit because of: the conditions of an
approved TMDL or TMDL implementation plan; a history of substantive non-compliance; or
other 30 TAC Chapter 205 considerations and requirements; or other site-specific
considerations.
F. Waivers
The TCEQ may waive permitting requirements for small regulated MS4 operators if the criteria are
met for Waiver Option 1 or 2. To obtain Waiver Option 1, the MS4 operator must submit the request
on a waiver form provided by the executive director. To obtain Waiver Option 2, the MS4 operator
must contact the executive director and coordinate the activities required to meet the waiver
conditions. A provisional waiver from permitting requirements begins two days after a completed
waiver form is postmarked for delivery to the TCEQ. Following review of the waiver form, the
executive director may: 1) determine that the waiver form is complete and confirm coverage under
the waiver by providing a notification and a waiver number, 2) determine that the waiver form is
incomplete and deny the waiver until a completed waiver form is submitted, or 3) deny the waiver
and require that permit coverage be obtained.
If the conditions of either waiver are not met by the MS4 operator, then the MS4 operator must
submit an application for coverage under this general permit or a separate TPDES permit application.
The TCEQ can, at any time, require a previously waived MS4 operator to comply with this general
permit or another TPDES permit if circumstances change so that the conditions of the waiver are no
longer met. Changed circumstances can also allow a regulated MS4 operator to request a waiver at
any time.
1. Waiver Option 1: The system serves a population of less than 1,000 within an urbanized
area and meets the following criteria:
(a) the system is not contributing substantially to the pollutant loadings of a physically
interconnected MS4 that is regulated by the NPDES / TPDES storm water program
Page 20
TPDES General Permit No. TXR040000
(40 CFR 9 122.32( d)); and
(b) if the system discharges any pollutant( s) that have been identified as a cause of
impairment of any water body to which the small MS4 discharges, storm water
controls are not needed based on wasteload allocations that are part of an EP A
approved or established "total maximum daily load" (TMDL) that addresses the
pollutant( s) of concern.
2. Waiver Option 2: The system serves a population under 10,000 and meets the following
criteria:
(a) the TCEQ has evaluated all waters of the United States, including small streams,
tributaries, lakes, and ponds, that receive a discharge from the small MS4;
(b) for all such waters, the TCEQ has determined that storm water controls are not
needed based on wasteload allocations that are part of an approved or established
TMDL that addresses the pollutant(s) of concern or, if a TMDL has not been
developed or approved, an equivalent analysis that determines sources and
allocations for the pollutant( s) of concern; and
( c ) the TCEQ has determined that future discharges from the small MS4 do not have the
potential to exceed Texas surface water quality standards, including impairment of
designated uses, or other significant water quality impacts, including habitat and
biological impacts.
Part III. Storm Water Management Program (SWMP)
To the extent allowable under state and local law, a SWMP must be developed and implemented according to
the requirements of Part III of this general permit, for storm water discharges that reach waters of the United
States, regardless of whether the discharge is conveyed through a separately operated storm sewer. The
SWMP must be developed to reduce the discharge of pollutants from the MS4 to the maximum extent
practicable (MEP), to protect water quality, and to satisfy the appropriate water quality requirements of the
Clean Water Act and the Texas Water Code. Existing programs or best management practices (BMPs) may
be used to fulfill the requirements of this general permit. The MS4 operator must develop the SWMP to
include the six minimum control measures described in Part IILA.l. through 6, and the operator may develop
and include the optional seventh minimum control measure in Part III.A. 7. Small MS4s have five years from
the date of issuance of this general permit to fully implement their SWMP. A discharger's compliance with
its approved SWMP will be deemed compliance with Part III of this permit.
Where the permittee lacks the authority to develop ordinances or to implement enforcement actions, the
permittee shall exert enforcement authority as required by this general permit for its facilities, employees, and
contractors. F or discharges from third party actions, the permittee shall perform inspections and exert
enforcement authority to the MEP.
If the permittee does not have enforcement authority and is unable to meet the goals of this general permit
through its own powers, then, unless otherwise stated in this general permit, the permittee shall perform the
Page 21
TPDES General Permit No. TXR040000
following action in order to meet the goals of the permit:
. Enter into interlocal agreements with municipalities where the small MS4 is located. These interlocal
agreements must state the extent to which the municipality will be responsible for inspections and
enforcement authority in order to meet the conditions of this general permit; or,
. if the permittee is unable to enter into inter-local agreements, notify the TCEQ's Field Operations
Division as needed to report discharges or incidents that it can not itself enforce against.
The controls and Best Management Practices (BMPs) included in the SWMP constitute effluent limitations
for the purposes of compliance with the requirements of 30 TAC Chapter 319, Subchapter B, related to
Hazardous Metals.
A. Minimum Control Measures
1. Public Education and Outreach on Storm Water Impacts
(a) A public education program must be developed and implemented to distribute
educational materials to the community or conduct equivalent outreach activities
that will be used to inform the public. The MS4 operator may determine the most
appropriate sections of the population at which to direct the program. The MS4
operator must consider the following groups and the SWMP shall provide
justification for any listed group that is not included in the program:
(1) residents;
(2) visitors;
(3) public service employees;
( 4) businesses;
(5) commercial and industrial facilities; and
(6) construction site personnel.
The outreach must inform the public about the impacts that storm water run-off can
have on water quality, hazards associated with illegal discharges and improper
disposal of waste, and steps that they can take to reduce pollutants in storm water
runoff.
(b) The MS4 operator must document activities conducted and materials used to fulfill
this control measure. Documentation shall be detailed enough to demonstrate the
amount of resources used to address each group. This documentation shall be
retained in the annual reports required in Part IV.B.2. of this general permit.
Page 22
TPDES General Permit No. TXR040000
2. Public Involvement/Participation
The MS4 operator must, at a minimum, comply with any state and local public notice
requirements when implementing a public involvement/participation program. It is
recommended that the program include provisions to allow all members of the public within
the small MS4 the opportunity to participate in SWMP development and implementation.
Correctional facilities will not be required to implement this MCM.
3. Illicit Discharge Detection and Elimination
(a) Illicit Discharges
A section within the SWMP must be developed to establish a program to detect and
eliminate illicit discharges to the small MS4. The SWMP must include the manner
and process to be used to effectively prohibit illicit discharges. To the extent
allowable under state and local law , an ordinance or other regulatory mechanism
must be utilized to prohibit and eliminate illicit discharges. Elements must include:
(1) Detection
The SWMP must list the techniques used for detecting illicit discharges;
and
(2) Elimination
The SWMP must include appropriate actions and, to the extent allowable
under state and local law , establish enforcement procedures for removing
the source of an illicit discharge.
(b) Allowable Non-Storm Water Discharges
Non-storm water flows listed in Part II.B and Part VI.B. do not need to be
considered by the MS4 operator as an illicit discharge requiring elimination unless
the operator of the small MS4 or the executive director identifies the flow as a
significant source of pollutants to the small MS4. In lieu of considering non-storm
water sources on a case-by-case basis, the MS4 operator may develop a list of
common and incidental non-storm water discharges that will not be addressed as
illicit discharges requiring elimination. If developed, the listed sources must not be
reasonably expected to be significant sources of pollutants either because of the
nature of the discharge or the conditions that are established by the MS4 operator
prior to accepting the discharge to the small MS4. If this list is developed, then all
local controls and conditions established for these listed discharges must be
described in the SWMP and any changes to the SWMP must be included in the
annual report described in Part IV.B.2. of this general permit, and must meet the
requirements of Part II.D.3. of the general permit.
Page 23
TPDES General Permit No. TXR040000
(c) Storm Sewer Map
(1) A map of the storm sewer system must be developed and must include the
following:
(i) the location of all outfalls;
(ii) the names and locations of all waters of the U.S. that receive
discharges from the outfalls; and
(iii) any additional information needed by the permittee to implement
its SWMP.
(2) The SWMP must include the source of information used to develop the
storm sewer map, including how the outfalls are verified and how the map
will be regularly updated.
4. Construction Site Storm Water Runoff Control
The MS4 operator, to the extent allowable under State and local law, must develop,
implement, and enforce a program to reduce pollutants in any storm water runoff to the small
MS4 from construction activities that result in a land disturbance of greater than or equal to
one acre or if that construction activity is part of a larger common plan of development or
sale that would disturb one acre or more of land. The MS4 operator is not required to
develop, implement, and/or enforce a program to reduce pollutant discharges from sites
where the construction site operator has obtained a waiver from permit requirements under
NPDES or TPDES construction permitting requirements based on a low potential for
erOSIon.
(a) The program must include the development and implementation of, at a minimum,
an ordinance or other regulatory mechanism to require erosion and sediment
controls, as well as sanctions to ensure compliance, to the extent allowable under
state and local law.
(b) Requirements for construction site contractors to, at a minimum:
(1) implement appropriate erosion and sediment control BMPs; and
(2) control waste such as discarded building materials, concrete truck washout
water, chemicals, litter, and sanitary waste at the construction site that may
cause adverse impacts to water quality.
(c) The MS4 operator must develop procedures for:
(1) site plan review which incorporate consideration of potential water quality
impacts;
Page 24
TPDES General Permit No. TXR040000
(2) receipt and consideration of information submitted by the public; and
(3) site inspection and enforcement of control measures to the extent allowable
under state and local law.
5. Post-Construction Storm Water Management in New Development and Redevelopment
To the extent allowable under state and local law, the MS4 operator must develop,
implement, and enforce a program to address storm water runoff from new development and
redevelopment projects that disturb greater than or equal to one acre of land, including
projects less than one acre that are part of a larger common plan of development or sale that
will result in disturbance of one or more acres, that discharge into the small MS4. The
program must ensure that controls are in place that would prevent or minimize water quality
impacts. The permittee shall:
(a) Develop and implement strategies which include a combination of structural and/or
non-structural BMPs appropriate for the community;
(b ) Use an ordinance or other regulatory mechanism to address post-construction runoff
from new development and redevelopment projects to the extent allowable under
state and local law; and
(c) Ensure adequate long-term operation and maintenance ofBMPs.
6. Pollution Prevention/Good Housekeeping for Municipal Operations
A section within the SWMP must be developed to establish an operation and maintenance
program, including an employee training component, that has the ultimate goal of preventing
or reducing pollutant runoff from municipal operations.
(a) Good Housekeeping and Best Management Practices (BMPs)
Housekeeping measures and BMPs (which may include new or existing structural or
non-structural controls) must be identified and either continued or implemented with
the goal of preventing or reducing pollutant runoff from municipal operations.
Examples of municipal operations and municipally owned areas include, but are not
limited to:
(1) park and open space maintenance;
(2) street, road, or highway maintenance;
(3) fleet and building maintenance;
( 4) storm water system maintenance;
(5) new construction and land disturbances;
Page 25
TPDES General Permit No. TXR040000
(6) municipal parking lots;
(7) vehicle and equipment maintenance and storage yards;
(8) waste transfer stations; and
(9) salt/sand storage locations.
(b ) Training
A training program must be developed for all employees responsible for municipal
operations subject to the pollution prevention/good housekeeping program. The
training program must include training materials directed at preventing and reducing
storm water pollution from municipal operations. Materials may be developed, or
obtained from the EP A, states, or other organizations and sources. Examples or
descriptions of training materials being used must be included in the SWMP.
(c) Structural Control Maintenance
IfBMPs include structural controls, maintenance of the controls must be performed
at a frequency determined by the MS4 operator and consistent with maintaining the
effectiveness of the BMP. The SWMP must list all of the following:
(1) maintenance activities;
(2) maintenance schedules; and
(3) long-term inspection procedures for controls used to reduce floatables and
other pollutants.
( d) Disposal of Waste
Waste removed from the small MS4 and waste that is collected as a result of
maintenance of storm water structural controls must be properly disposed. A section
within the SWMP must be developed to include procedures for the proper disposal
of waste, including:
(1) dredge spoil;
(2) accumulated sediments; and
(3) floatables.
(e) Municipal Operations and Industrial Activities
The SWMP must include a list of all:
Page 26
TPDES General Permit No. TXR040000
(1) municipal operations that are subject to the operation, maintenance, or
training program developed under the conditions of this section; and
(2) municipally owned or operated industrial activities that are subject to
TPDES industrial storm water regulations.
7 . Authorization for Municipal Construction Activities
The development of a MCM for municipal construction activities is an optional measure and
is an alternative to the MS4 operator seeking coverage under TPDES general permit
TXR150000. Additionally, contractors working for the permittee are not required to obtain a
separate authorization if they do not meet the definition of a "construction site operator," as
long as the permittee meets the status of construction site operator. Permittees that choose to
develop this measure will be authorized to discharge storm water and certain non-storm
water from construction activities where the permittee can meet the definition of
"construction site operator" in Part I of this general permit. The authorization to discharge
under this MCM is limited to the regulated area, such as the portion of the MS4 located
within an urbanized area or the area designated by TCEQ as requiring coverage. However,
an MS4 operator may also utilize this MCM over additional portions of their MS4 that are
also in compliance with all of the MCMs listed in this general permit. This MCM must be
developed as a part of the SWMP that is submitted with the NOI for permit coverage. If this
MCM is developed after submitting the initial NOI, a NOC must be submitted notifying the
executive director of this change, and identifying the geographical area or boundary where
the activities will be conducted under the provisions of this general permit. Utilization of
this MCM does not preclude a small MS4 from obtaining coverage under the TPDES
Construction General Permit, TXR150000, or under an individual TPDES permit.
(a) The MCM must include:
(1) a description of how construction activities will generally be conducted by
the permittee so as to take into consideration local conditions of weather,
soils, and other site specific considerations;
(2) a description of the area that this MCM will address and where the
permittee's construction activities are covered (e.g. within the boundary of
the urbanized area, the corporate boundary, a special district boundary, an
extra territorial jurisdiction, or other similar jurisdictional boundary); and
(3) either a description of how the permittee will supervise or maintain
oversight over contractor activities to ensure that the SWP3 requirements
are properly implemented at the construction site; or how the permittee will
make certain that contractors have a separate authorization for storm water
discharges.
(4) a general description of how a SWP3 shall be developed, according to Part
VI.E. of this general permit, for each construction site.
Page 27
TPDES General Permit No. TXR040000
B. General Requirements
Permittees must provide documentation of the development, implementation, and evaluation of the
S WMP. The documentation must be included in the S WMP and may be required to be submitted in
the annual report required in Part IV.B.2. of this general permit. At a minimum, the documentation
must include:
1. a list of any public or private entities assisting with the development or implementation of
the SWMP;
2. a list of all BMPs and measurable goals for each of the MCMs;
3. a schedule for the implementation of all SWMP requirements;
4. a description of how each measurable goal will be evaluated;
5. a rationale statement that addresses the overall program, including how the BMPs and
measurable goals were selected; and
6. if applicable, a list of all MS4 operators contributing to the development and implementation
of the SWMP, including a clear description of the contribution.
Part IV. Recordkeeping and Reporting
A. Recordkeeping
1. The permittee must retain all records, a copy of this TPDES general permit, and records of
all data used to complete the application (NOI) for this general permit and satisfy the public
participation requirements, for a period of at least three years, or for the remainder of the
term of this general permit, whichever is longer. This period may be extended by request of
the executive director at any time.
2. The permittee must submit the records to the executive director only when specifically asked
to do so. The SWMP required by this general permit (including a copy of the general
permit) must be retained at a location accessible to the TCEQ.
3. The permittee must make the NOI and the SWMP available to the public if requested to do
so in writing. Copies of the SWMP must be made available within 10 working days of
receipt of a written request. Other records must be provided in accordance with the Texas
Public Information Act. However, all requests for records from federal facilities must be
made in accordance with the Freedom of Information Act.
4. The period during which records are required to be kept shall be automatically extended to
the date of the final disposition of any administrative or judicial enforcement action that
maybe instituted against the permittee.
Page 28
TPDES General Permit No. TXR040000
B. Reporting
1. General Reporting Requirements
(a) Noncompliance Notification
According to 30 TAC 9 305.125(9), any noncompliance which may endanger
human health or safety, or the environment, must be reported by the permittee to the
TCEQ. Report of such information must be provided orally or by electronic
facsimile transmission (FAX) to the TCEQ regional office within 24 hours of
becoming aware of the noncompliance. A written report must be provided by the
permittee to the TCEQ regional office and to the TCEQ Enforcement Division (MC-
224) within five working days of becoming aware of the noncompliance. The
written report must contain:
(1 ) a description of the noncompliance and its cause;
(2) the potential danger to human health or safety, or the environment;
(3) the period of noncompliance, including exact dates and times;
(4) if the noncompliance has not been corrected, the anticipated time it is
expected to continue; and
(5) steps taken or planned to reduce, eliminate, and prevent recurrence of the
noncompliance, and to mitigate its adverse effects.
(b ) Other Information
When the permittee becomes aware that it either submitted incorrect information or
failed to submit complete and accurate information requested in an NOI, NOT, or
NOC, or any other report, it must promptly submit the facts or information to the
executive director.
2. Annual Report
The MS4 operator must submit a concise annual report to the executive director within 90
days of the end of each permit year. The annual report must address the previous permit
year. The first permit year for annual reporting purposes shall begin on the date of permit
issuance, and shall last for one year. Subsequent calendar years will begin on the
anniversary date of permit issuance and last for one year. The MS4 operator must also make
a copy of the annual report readily available for review by TCEQ personnel upon request.
The report must include:
(a) The status of the compliance with permit conditions, an assessment of the
appropriateness of the identified BMPs, progress towards achieving the statutory
Page 29
TPDES General Permit No. TXR040000
goal of reducing the discharge of pollutants to the MEP, the measurable goals for
each of the MCMs, and an evaluation of the success of the implementation of the
measurable goals;
(b) Status of any additional control measures implemented by the permittee (if
applicable );
(c) Any MCM activities initiated before permit issuance may be included, under the
appropriate headings, as part of the first year's annual report;
(d) A summary of the results of information (including monitoring data) collected and
analyzed, if any, during the reporting period used to assess the success of the
program at reducing the discharge of pollutants to the MEP;
(e) A summary of the storm water activities the MS4 operator plans to undertake during
the next reporting cycle;
(f) Proposed changes to the SWMP, including changes to any BMPs or any identified
measurable goals that apply to the program elements;
(g) The number of municipal construction activities authorized under this general permit
and the total number of acres disturbed;
(h) The number of non-municipal construction activities that occurred within the
jurisdiction of the permittee (as noticed to the permittee by the construction
operator); and
(i) Notice that the MS4 operator is relying on another government entity to satisfy some
of its permit obligations (if applicable).
An annual report must be prepared whether or not the NOI and SWMP has been approved by
the TCEQ. If the permittee has either not implemented the SWMP or not begun to
implement the SWMP because it has not received approval of the NOI and SWMP, then the
annual report may include that information.
Ifpermittees share a common SWMP, all permittees must contribute to a system-wide report
(if applicable);
Each permittee must sign and certify the annual report in accordance with 30 T AC 9 305.128
(relating to Signatories to Reports); and
The annual report must be submitted to the following address:
Texas Commission on Environmental Quality
Storm Water & Pretreatment Team; MC - 148
P.O. Box 13087
Austin, Texas 78711-3087
Page 30
TPDES General Permit No. TXR040000
A copy of the annual report must also be submitted to the TCEQ Regional Office that serves
the area of the regulated small MS4.
If available, electronic submission of annual reports is encouraged. The Federal Waste
Reduction Act and the Government Paperwork Elimination Act encourages governmental
agencies to use electronic submission. See the TCEQ website at, for
additional information and instructions.
Part V. Standard Permit Conditions
A. The permittee has a duty to comply with all permit conditions. Failure to comply with any permit
condition is a violation of the general permit and statutes under which it was issued, and is grounds
for enforcement action, for terminating coverage under this general permit, or for requiring a
discharger to apply for and obtain an individual TPDES permit.
B. Authorization under this general permit may be suspended or revoked for cause. Filing a notice of
planned changes or anticipated non-compliance by the permittee does not stay any permit condition.
The permittee must furnish to the executive director, upon request and within a reasonable timeframe,
any information necessary for the executive director to determine whether cause exists for revoking,
suspending, or terminating authorization under this general permit. Additionally, the permittee must
provide to the executive director, upon request, copies of all records that the permittee is required to
maintain as a condition of this general permit.
C. It is not a defense for a discharger in an enforcement action that it would have been necessary to halt
or reduce the permitted activity to maintain compliance with the permit conditions.
D. Inspection and entry shall be allowed under Texas Water Code Chapters 26-28, Health and Safety
Code 99361.032-361.033 and 361.037, and 40 Code of Federal Regulations (CFR) 9122.41(i). The
statement in Texas Water Code 9 26.014 that commission entry of a facility shall occur according to
an establishment's rules and regulations concerning safety, internal security, and fire protection is not
grounds for denial or restriction of entry to any part of the facility or site, but merely describes the
commission's duty to observe appropriate rules and regulations during an inspection.
E. The discharger is subject to administrative, civil, and criminal penalties, as applicable, under Texas
Water Code, Chapters 26, 27, and 28, and the Texas Health and Safety Code, Chapter 361 for
violations including but not limited to the following:
a. negligently or knowingly violating CW A, 99 301,302,306,307,308,318, or 405, or any
condition or limitation implementing any sections in a permit issued under CW A, 9 402; and
b. knowingly making any false statement, representation, or certification in any record or other
document submitted or required to be maintained under a permit, including monitoring
reports or reports of compliance or noncompliance.
F . All reports and other information requested by the executive director must be signed by the person
Page 31
TPDES General Permit No. TXR040000
and in the manner required by 30 TAC 9 305.128 (relating to Signatories to Reports).
G. Authorization under this general permit does not convey property or water rights of any sort and does
not grant any exclusive privilege.
H. The permittee shall implement its SWMP on any new areas under its jurisdiction that are located in a
VA or that are designated by the TCEQ. Implementation of the SWMP in these areas is required
three (3) years from acquiring the new area, or five (5) years from the date of the original SWMP,
whichever is later.
Part VI. Authorization for Municipal Construction Activities
The MS4 operator may obtain authorization under TPDES general permit TXR150000 to discharge storm
water runoff from each construction activity performed by the MS4 operator that results in a land disturbance
of one (1) or more acres of land. Alternatively, the MS4 operator may develop the SWMP to include this
optional seventh (7th) storm water MCM if the eligibility requirements in Part VLA. are met. If an MS4
operator decides to utilize this MCM, then the MS4 operator must include the MCM it in its SWMP submitted
with the NOI or submit an NOC notifying the executive director of the addition of this MCM to its SWMP.
The MS4 operator must identify the geographic area or boundary where the construction activities will be
conducted under the provisions of this general permit. If the small MS4 meets the terms and requirements of
this general permit, then discharges from these construction activities may be authorized under this general
permit as long as they occur within the regulated geographic area of the small MS4. An MS4 operator may
utilize this MCM over additional portions of their MS4 if those areas are also in compliance with all MCMs
listed in this general permit. Even if an MS4 operator has developed this optional seventh storm water MCM,
the MS4 operator may apply under TPDES general permit TXR150000 for authorization for particular
municipal construction activities including those activities that occur during periods of low potential for
erosion (for which no SWP3 must be developed).
A. Eligible Construction Sites
Discharges from construction activities within the regulated area where the MS4 operator meets the
definition of construction site operator are eligible for authorization under this general permit.
Discharges from construction activities outside of the regulated area, where the MS4 operator meets
the definition of construction site operator, are only eligible for authorization under this general
permit in those areas where the MS4 operator meets the requirements of Parts IILA.l. through IILA.6
of this general permit, related to MCMs.
B. Discharges Eligible for Authorization
1. Storm Water Associated with Construction Activity
Discharges of storm water runoff from small and large construction activities may be
authorized under this general permit.
Page 32
TPDES General Permit No. TXR040000
2. Discharges of Storm Water Associated with Construction Support Activities
Discharges of storm water runoff from construction support activities, including concrete
batch plants, asphalt batch plants, equipment staging areas, material storage yards, material
borrow areas, and excavated material disposal areas may be authorized under this general
permit provided:
(a) the activity is located within a I-mile distance from the boundary of the permitted
construction site and directly supports the construction activity;
(b) a storm water pollution prevention plan is developed according to the provisions of
this general permit and includes appropriate controls and measures to reduce erosion
and discharge of pollutants in storm water runoff from the supporting industrial
activity site; and
(c) the construction support activity either does not operate beyond the completion date
of the construction activity or obtains separate TPDES authorization for discharges
as required.
3. Non-storm Water Discharges
The following non-storm water discharges from construction sites authorized under this
general permit are also eligible for authorization under this MCM:
(a) discharges from fire fighting activities (fire fighting activities do not include
washing of trucks, run-off water from training activities, test water from fire
suppression systems, and similar activities);
(b) fire hydrant flushings;
( c) vehicle, external building, and pavement wash water where detergents and soaps are
not used and where spills or leaks of toxic or hazardous materials have not occurred
(unless all spilled material is removed)
( d) water used to control dust;
(e) potable water sources including waterline flushings;
(f) air conditioning condensate; and
(g) uncontaminated ground water or spring water, including foundation or footing
drains where flows are not contaminated with industrial materials such as solvents.

E. Storm Water Pollution Prevention Plan (SWP3)
Operators of municipal construction activities that qualify for coverage under this general permit and
that discharge storm water associated with construction activities that reach waters of the U.S. must:
1. develop a SWP3 according to the provisions of this general permit that covers the entire site
and begin implementation of that plan prior to commencing construction activities;
2. post a signed copy of the notice contained in Attachment 1 of this general permit in a
location at the construction site where it is readily available for viewing prior to commencing
construction activities and maintain the notice in that location until completion of the
construction activity and final stabilization of the site;
3. ensure the proj ect specifications allow or provide that adequate BMPs may be developed and
modified as necessary to meet the requirements of this general permit and the SWP3;
4. ensure all contractors are aware of the SWP3 requirements, are aware that municipal
personnel are responsible for the day-to-day operations of the SWP3, and who to contact
concerning SWP3 requirements; and
5. ensure that the SWP3 identifies the municipal personnel responsible for implementation of
control measures described in the plan.
Page 34
TPDES General Permit No. TXR040000
F. Effective Date of Coverage
Operators of construction activities eligible for coverage under this general permit are authorized to
discharge storm water associated with construction activity from a site 48 hours from the time that the
signed notice is posted at the site.
G. Deadlines for SWP3 Preparation and Compliance
The SWP3 must:
1. be completed and initially implemented prior to commencing construction activities that
result in soil disturbance;
2. be updated as necessary to reflect the changing conditions of new contractors, new areas of
responsibility, and changes in best management practices; and
3. provide for compliance with the terms and conditions of this general permit.
H. Plan Review and Making Plans Available
The SWP3 must be retained on-site at the construction site or made readily available at the time of an
on-site inspection to: the executive director; a federal, state, or local agency approving sediment and
erosion plans, grading plans, or storm water management plans; local government officials; and the
operator of a municipal separate storm sewer receiving discharges from the site.
I. Keeping Plans Current
The permittee must amend the SWP3 whenever:
1. there is a change in design, construction, operation, or maintenance that has a significant
effect on the discharge of pollutants and that has not been previously addressed in the S WP3;
or
2. results of inspections or investigations by site operators, authorized TCEQ personnel, or a
federal, state or local agency approving sediment and erosion plans indicate the SWP3 is
proving ineffective in eliminating or significantly minimizing pollutants in discharges
authorized under this general permit.
J. Contents of SWP3
The SWP3 must include, at a minimum, the information described in this section.
1. A site description, or project description, must be developed to include:
(a) a description of the nature of the construction activity, potential pollutants and
sources;
Page 35
TPDES General Permit No. TXR040000
(b) a description of the intended schedule or sequence of major activities that will
disturb soils for major portions of the site;
(c) the number of acres of the entire construction site property and the total number of
acres of the site where construction activities will occur, including off-site material
storage areas, overburden and stockpiles of dirt, and borrow areas;
( d) data describing the soil type or the quality of any discharge from the site;
(e) a map showing the general location of the site (e.g. a portion of a city or county
map);
(f) a detailed site map indicating the following:
(1) drainage patterns and approximate slopes anticipated after major grading
activities;
(2) areas where soil disturbance will occur;
(3) areas which will not be disturbed;
(4) locations of all major structural controls either planned or in place;
(5) locations where stabilization practices are expected to be used;
(6) locations of off-site material, waste, borrow or equipment storage areas;
(7) surface waters (including wetlands) either adjacent or in close proximity;
and
(8) locations where storm water discharges from the site directly to a surface
water body.
(g) the location and description of asphalt plants and concrete plants (if any) providing
support to the construction site and that are also authorized under this general
permit;
(h) the name of receiving waters at or near the site that will be disturbed or that will
receive discharges from disturbed areas of the project; and
(i) a copy of Part VI of this TPDES general permit.
2. The SWP3 must describe the structural and the non-structural controls (best management
practices) that will be used to minimize pollution in runoff. The description must identify
the general timing or sequence for implementation and the party responsible for
implementation. At a minimum, the description must include the following components:
Page 36
TPDES General Permit No. TXR040000
(a) Erosion and Sediment Controls
(1) Erosion and sediment controls must be designed to retain sediment on-site
to the maximum extent practicable with consideration for local topography
and rainfall.
(2) Control measures must be properly selected, installed, and maintained
according to the manufacturer's or designer's specifications. If periodic
inspections or other information indicates a control has been used
incorrectly, or that the control is performing inadequately, the operator must
replace or modify the control.
(3) Sediment must be removed from sediment traps and sedimentation ponds no
later than the time that design capacity has been reduced by 50%.
( 4) If sediment escapes the site, accumulations must be removed at a frequency
to minimize further negative effects and, whenever feasible, prior to the
next rain event.
(5) Controls must be developed to limit offsite transport of litter, construction
debris, and construction materials by storm water runoff.
3. Stabilization Practices
The SWP3 must include a description of interim and permanent stabilization practices for the
site, including a schedule of when the practices will be implemented. Site plans should
ensure that existing vegetation is preserved where it is possible.
(a) Stabilization practices may include but are not limited to: establishment of
temporary vegetation, establishment of permanent vegetation, mulching, geotextiles,
sod stabilization, vegetative buffer strips, protection of existing trees and vegetation
and other similar measures.
(b ) The following records must be maintained and either attached to or referenced in the
SWP3 and made readily available upon request to the parties in Part VI.H. of this
general permit:
(1) the dates when major grading activities occur;
(2) the dates when construction activities temporarily or permanently cease on a
portion of the site; and
(3) the dates when stabilization measures are initiated.
(c) Stabilization measures must be initiated as soon as practicable in portions of the site
where construction activities have temporarily or permanently ceased, and except as
provided in (1 ) through (3) below, must be initiated no more than fourteen (14) days
Page 37
TPDES General Permit No. TXR040000
after the construction activity In that portion of the site has temporarily or
permanently ceased.
(1) Where the initiation of stabilization measures by the 14th day after
construction activity temporarily or permanently ceased is precluded by
snow cover or frozen ground conditions, stabilization measures must be
initiated as soon as practicable.
(2) Where the initiation of stabilization measures by the 14th day after
construction activity has temporarily or permanently ceased is precluded by
seasonably arid conditions, stabilization measures must be initiated as soon
as practicable. These conditions exist in arid areas (areas with an average
rainfall of 0 to 1 0 inches), semiarid areas (areas with an average annual
rainfall of 1 0 to 20 inches), and other areas experiencing droughts.
(3) Where construction activity on a portion of the site is temporarily ceased
and earth disturbing activities will be resumed within twenty-one (21) days,
temporary stabilization measures do not have to be initiated on that portion
of site.
4. Structural Control Practices
The SWP3 must include a description of any structural control practices used to divert flows
away from exposed soils, to limit the contact of runoff with disturbed areas, or to lessen the
off-site transport of eroded soils.
(a) Sediment basins are required, where feasible, for common drainage locations that
serve an area with ten (10) or more acres that remain disturbed at anyone time.
Sediment basins may be either temporary or permanent, but must be designed to
store either the calculated volume of runoff from a 2 year, 24 hour storm from
acreage drained, or designed to provide 3,600 cubic feet of storage per acre drained.
When calculating the volume of runoff from a 2-year, 24-hour storm event, it is not
required to include the flows from offsite areas and flow from onsite areas that are
either undisturbed or have already undergone final stabilization, if these flows are
diverted around both the disturbed areas of the site and the sediment basin. In
determining whether installing a sediment basin is feasible, the permittee may
consider factors such as site soils, slope, available area on site, public safety, and
other similar considerations. Where sediment basins are not feasible, equivalent
control measures, which may include a series of smaller sediment basins, must be
used. At a minimum, silt fences, vegetative buffer strips, or equivalent sediment
controls are required for all down slope boundaries (and for those side slope
boundaries deemed appropriate as dictated by individual site conditions) of the
construction area.
(b) Sediment traps and sediment basins may be used to control solids in storm water
runoff for drainage locations serving less than ten (10) acres. At a minimum, silt
fences, vegetative buffer strips, or equivalent sediment controls are required for all
Page 38
TPDES General Permit No. TXR040000
down slope boundaries (and for those side slope boundaries deemed appropriate as
dictated by individual site conditions) of the construction. Alternatively, a sediment
basin providing storage for a calculated volume of runoff from these areas for a 2-
year, 24- hour storm or 3,600 cubic feet of storage per acre drained may be
provided.
5. Permanent Storm Water Controls
A description of any measures that will be installed during the construction process to
control pollutants in storm water discharges that will occur after construction operations have
been completed must be included in the SWP3. Permittees are only responsible for the
installation and maintenance of storm water management measures prior to final stabilization
of the site .
6. Other Controls
(a) Off-site vehicle tracking of sediments and the generation of dust must be minimized.
(b) The SWP3 must include a description of construction and waste materials expected
to be stored on-site and a description of controls to reduce pollutants from these
materials.
(c) The SWP3 must include a description of pollutant sources from areas other than
construction (including storm water discharges from dedicated asphalt plants and
dedicated concrete plants), and a description of controls and measures that will be
implemented at those sites to minimize pollutant discharges.
7. Approved State and Local Plans
(a) Permittees must ensure the SWP3 is consistent with requirements specified in
applicable sediment and erosion site plans or site permits, or storm water
management site plans or site permits approved by federal, state, or local officials.
(b) SWP3s must be updated as necessary to remain consistent with any changes
applicable to protecting surface water resources in sediment erosion site plans or site
permits, or storm water management site plans or site permits approved by state or
local official for which the permittee receives written notice.
8. Maintenance
All erosion and sediment control measures and other protective measures identified in the
SWP3 must be maintained in effective operating condition. If through inspections the
permittee determines that BMPs are not operating effectively, maintenance must be
performed before the next anticipated storm event or as necessary to maintain the continued
effectiveness of storm water controls. If maintenance prior to the next anticipated storm
event is impracticable, maintenance must be scheduled and accomplished as soon as
practicable.
Page 39
TPDES General Permit No. TXR040000
9. Inspections of Controls
(a) Personnel provided by the permittee and familiar with the SWP3 must inspect
disturbed areas of the construction site that have not been finally stabilized, areas
used for storage of materials that are exposed to precipitation, all structural control
measures for effectiveness and necessary maintenance, and locations where vehicles
enter or exit the site for evidence of off-site tracking. Inspections must occur at least
once every fourteen (14) calendar days and within twenty four (24) hours of the end
of a storm event of 0.5 inches or greater. As an alternative, the SWP3 may be
developed to require that these inspections will occur at least once every seven (7)
calendar days; in which case additional inspections are not required following each
qualifying storm event. If this alternative schedule is developed, the inspection must
occur on a specifically defined day, regardless of whether or not there has been a
rainfall event since the previous inspection.
Where sites have been finally or temporarily stabilized, where runoff is unlikely due
to winter conditions (e.g. site is covered with snow, ice, or frozen ground exists), or
during seasonal arid periods in arid areas (areas with an average annual rainfall of 0
to 10 inches) and semi-arid areas (areas with an average annual rainfall of 10 to 20
inches), inspections must be conducted at least once every month.
(b) Personnel provided by the permittee and familiar with the SWP3 must inspect all
accessible discharge locations to determine if erosion control measures are effective
in preventing visually noticeable changes to receiving waters, including persistent
cloudy appearance in water color and noticeable accumulation of sediments.
Where discharge locations are inaccessible, nearby downstream locations must be
inspected to the extent that such inspections are practicable. The frequency for these
inspections must be established by the permittee in the SWP3 with consideration for
local rainfall and soil, but must occur at least once during the construction activity if
a discharge occurs.
(c) The SWP3 must be modified based on the results of inspections, as necessary, to
better control pollutants in runoff. Revisions to the SWP3 must be completed within
seven (7) calendar days following the inspection. If existing BMPs are modified or
if additional BMPs are necessary, an implementation schedule must be described in
the SWP3 and wherever possible those changes implemented before the next storm
event. If implementation before the next anticipated storm event is impracticable,
these changes must be implemented as soon as practicable.
(d) A report summarizing the scope of the inspection, names and qualifications of
personnel making the inspection, the dates of the inspection, and major observations
relating to the implementation of the SWP3 must be made and retained as part of the
SWP3. Major observations should include: the locations of discharges of sediment
or other pollutants from the site; locations of BMPs that need to be maintained;
locations of BMPs that failed to operate as designed or proved inadequate for a
Page 40
TPDES General Permit No. TXR040000
particular location; and locations where additional BMPs are needed.
(e) Actions taken as a result of inspections must be described within, and retained as a
part of, the SWP3. Reports must identify any incidents of non-compliance. Where
a report does not identify any incidents of non-compliance, the report must contain a
certification that the facility or site is in compliance with the SWP3 and this permit.
10. The SWP3 must identify and ensure the implementation of appropriate pollution prevention
measures for all eligible non-storm water components of the discharge.
K. Additional Retention of Records
The permittee must retain the following records for a minimum period of three (3) years from the
date that final stabilization has been achieved on all portions of the site. Records include:
1. a copy of the SWP3; and
2. all reports and actions required by this general permit, including a copy of the site notice.

Permit Requirements for Updates to the SWMP
The City is permitted to revise this SWMP during the permit term. The TCEQ permit, located in
Appendix G, details the requirements and allowances for making modifications to the storm
water management program. This can include addition, deletion, or modification of BMPs.
Below is the specific permit language with respect to SWMP modifications.
"Changes may be made to the SWMP during the permit term. Changes that are made to the
SWMP before the NOI is approved by the TCEQ must be submitted in a letter providing
supplemental information to the NOI. Changes to the SWMP that are made after TCEQ
approval of the NOI and SWMP may be made following written approval of the changes from
the TCEQ, except that written approval is not required for the following changes:
(a) Adding components, controls, or requirements to the SWMP; or replacing a BMP with an
equivalent BMP, may be made by the permittee at any time upon submittal of a
notice of change (NOC) form to the address specified on the form to the TCEQ.
(b) Replacing a less effective or infeasible BMP specifically identified in the SWMP with an
alternate BMP may be requested at any time. Changes must be submitted on an
NOC form to the address specified on the form. Unless denied in writing by the
TCEQ, the change shall be considered approved and may be implemented by the
permittee 60 days from submitting the request. Such requests must include the
following:
(1) an explanation of why the BMP was eliminated;
(2) an explanation of the effectiveness of the replacement BMP; and
(3) an explanation of why the replacement BMP is expected to achieve the goals of
the replaced BMP."
A record of modifications to the SWMP should be documented on the following Record of Plan
Updates. A copy of any communication to TCEQ regarding SWMP modification, as well as
written approval from TCEQ of proposed SWMP modifications, should also be maintained in this
Appendix.
