1.0 INTRODUCTION
1.1 Regulatory Requirement
The Clean Water Act (CWA) is a federal law that establishes environmental programs, including
the National Pollutant Discharge Elimination (NPDES) program, to protect the Nation's waters
and directs the U.S. Environmental Protection Agency (EPA) to issue rules on how to implement
this law. Under the NPDES program, a municipal stormwater program was developed in two
phases, Phase I and Phase II.
Phase I of the EPA municipal stormwater program was promulgated in 1990 under the authority
of the CWA. Phase I relied on the NPDES permit coverage to address stormwater runoff from
medium and large municipal separate storm sewer systems (MS4s), serving populations of
100,000 and greater.
The NPDES Stormwater Phase II regulations, which target small MS4s located fully or partially
within an “urbanized area” and construction activities disturbing more than one acre of land,
were promulgated by the Environmental Protection Agency (EPA) on December 8, 1999. These
regulations apply to all jurisdictions within a delineated urbanized area regardless of individual
population. The latest decennial census (2000) by the U.S. Census Bureau identified the Town
of Hickory Creek as a community that is operating an MS4 within an urbanized area, and thus is
regulated under the NPDES Stormwater Phase II regulations.
The Texas Commission on Environmental Quality (TCEQ) was granted the authority in 1998
from the EPA to administer the Texas Pollutant Discharge Elimination System (TPDES). This
authority is granted through a Memorandum of Agreement with the EPA to administer the
NPDES system as it applies to the State of Texas. The TPDES requirements must be at least
as stringent as those set forth by the NPDES program.
This program requires that the Town of Hickory Creek:
Reduce the discharge of pollutants to the maximum extent practicable (MEP);
Protect water quality;
Satisfy the appropriate water quality requirements of the Clean Water Act; and,
Manage stormwater quality activities through the Stormwater Management Program
(SWMP).
The Town of Hickory Creek has developed the SWMP in accordance with the requirements of
the TPDES Small MS4 General Permit TXR040000 for obtaining authorization for stormwater
discharges and certain non-stormwater discharges. The SWMP has been developed to reduce
the amount of pollutants carried into the MS4 by stormwater runoff as required by the TPDES
General Permit.
The Town of Hickory Creek 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 Town’s stormwater
quality to the MEP. The specific activities to be implemented are Best Management Practices
TPDES Phase II MS4 General Permit
Stormwater Management Program
Town of Hickory Creek, Texas
June 2014 Page 2
(BMPs). The SWMP must also set measurable goals and provide a schedule for the
implementation of the BMPs. Various BMPs must be developed for each of the five minimum
control measures (MCMs) that are required by the Phase II Rule. The five required MCMs are:
1. Public Education, Outreach, and Involvement;
2. Illicit Discharge Detection and Elimination;
3. Construction Site Stormwater Runoff Control;
4. Post-Construction Stormwater Management in New Development and Redevelopment;
and
5. Pollution Prevention and Good Housekeeping for Municipal Operations.
The MS4 General Permit includes a sixth MCM that only applies to Level 4 MS4s that was not
included. The permit also includes the optional seventh MCM that address’s stormwater from
municipal construction activities. The Town of Hickory Creek will not consider the seventh MCM
at this time.

2.0 PROGRAM OVERVIEW
2.1 Background Information for the Town of Hickory Creek
The Town of Hickory Creek is located north of the Lewisville Lake in Denton County, Texas.
Hickory Creek is bordered by the City of Corinth, City of Lake Dallas, City of Highland Village
and City of Lewisville. The Town was incorporated on 1963 and currently has a land area of 4.6
square miles. In 2010, the population of Hickory Creek was estimated at 3,247. A location map
is presented in Figure 1.
The Town lies within the Lake Lewisville Watershed. The Town has approximately 2 stream
miles within the Town limits and approximately 0.8 miles of the 2 stream miles are with the
United States of America Corps of Engineer’s property. The stream miles within Hickory Creek
are comprised of Carter Branch, Carter Branch Tributary 1, and Lake Lewisville Unnamed
Tributary 26. Most of the streams flows in a southeasterly direction and discharges into Lake
Lewisville.
2.2 Stormwater Management Program Development
The hydrology and water quality concerns of the Town of Hickory Creek have been considered
in developing this Stormwater Management Program. The Plan herein describes the
development and implementation of the Stormwater Management Program. In preparing this
Plan, the Town of Hickory Creek has considered different activities, municipal and public, that
have stormwater impacts. Some of the municipal departments that have been identified as
having stormwater impacts include Public Works, Police, Fire, Parks and Recreation, and
Planning and Zoning.
This SWMP includes the five MCMs required by the TPDES program and the EPA Phase II
Final Rule. Each of the five required MCMs includes a summary that outlines the TCEQ
requirements for that component of the plan. The summary is followed by specific BMPs that
include measurable goals and target dates, and the implementing responsibility within the Town
of Hickory Creek.
2.3 Public Review and Comment of the Stormwater Management Program
In accordance with the general permit TXR040000, Part II, Section E, Number 12, the SWMP
will be available for review at the Town Hall, located at 1075 Ronald Reagan Ave., Hickory
Creek, Texas 75065.
2.4 Annual Reporting
The Town of Hickory Creek will track BMP activities, results, and changes to the SWMP through
an annual report that will be submitted to the TCEQ Executive Director within 90 days at the end
of each permit year. The annual report will include factors required by Part IV, Section B,
Number 2 of the general permit, including:
a) The status of the compliance with permit conditions, assessments of BMPs, progress
towards achieving the statutory goal of reducing the discharge of pollutants to the MEP,
measurable goals for each of the MCMs, and an evaluation of the success of the
implementation of the measureable goals,
TPDES Phase II MS4 General Permit
Stormwater Management Program
Town of Hickory Creek, Texas
June 2014 Page 4
b) A summary of the results of information collected and analyzed including monitoring data
used to assess the success of the program,
c) A summary of the stormwater activities the MS4 operator plans to undertake during the
next reporting year,
d) And any changes to the SWMP, as assessed to keep the Town of Hickory Creek in
compliance with the general permit conditions.
The Town of Hickory Creek does not have enough employees to perform municipal public
works. All public works improvements are contracted out.
The Town of Hickory Creek MS4 annual reporting year shall be Calendar Year, which the
reporting year will end on December 31
st
and Annual report will be submitted to TCEQ by March
31
st
(90 days of Calendar Year).
2.5 Recordkeeping and Tracking
In accordance with the general permit TXR040000, Part IV, Section A, the Town of Hickory
Creek will retain all records, a copy of the TPDES general permit, and records of all data used
to complete the application (NOI) for the general permit, and satisfy the public participation
requirements, for a minimum of three years or for the remainder of term of this general permit,
whichever is longer, and make this information available to the public if requested to do so in
writing within 10 working days of the request.

3.0 TOWN OF HICKORY CREEK STORMWATER MANAGEMENT PROGRAM
This section recommends specific methods to implement during the next five years in order to
develop stormwater management programs that match community priorities and also enable the
Town to comply with the TCEQ General Permit as an operator of a small MS4.
3.1 Introduction
The Town of Hickory Creek’s Stormwater Management Program must address the five MCMs
outlined in TCEQ’s General Permit TXR040000 for small municipal separate storm sewer
systems (MS4s). As stated in Section 1, each MCM has permit requirements; actions that the
Town needs to take to maintain compliance with the TPDES General Permit.
The BMPs presented herein have been proposed because they are appropriate for the Town of
Hickory Creek’s stormwater system. The BMPs are considered measurable, are anticipated to
provide significant benefits in the Town’s stormwater quality, and are achievable. Many of these
BMPs build upon efforts initiated by the Town as part of the previous SWMP. The Town is
committed to a proactive approach to stormwater management for the community’s health and
to be good environmental stewards. Based on the General Permit’s requirements and
recommendations, the following recommended actions are categorized by the five(5) Phase II
Minimum Control Measures.

3.2 MCM1 Public Education, Outreach, and Involvement
Public education, outreach, and involvement are an important MCM. This MCM can be
accomplished in a number of different ways, most of which are already established and/or
accessible. In the past, the Town has found that newsletter articles were an effective ways to
reach the Town’s residents.
The Town of Hickory Creek recognizes the benefits of direct involvement in the Town’s
stormwater program by members of the public. The Town involves its residents by obtaining
feedback from them in a number of established committees, including on-line communication,
and public meetings.
Public involvement differs from public education in that it not only informs the public, but also
provides opportunities for direct citizen action. When citizens participate in a project’s decision-
making process, they are more likely to support the final outcome. This plan describes ways in
which the community can play an active role in developing and implementing the Town’s
stormwater management program. An informed and involved public can be a valuable
information resource and can help build compliance with the program. The public involvement
and participation program is also a requirement of the TPDES program and EPA NPDES Phase
II Final Rule.
General Permit Requirements:
(a) A public education program must be developed to distribute educational materials to
the community or conduct equivalent outreach activities that will be used to inform the
public. The Town of Hickory Creek may determine the most appropriate sections of
the population at which to direct the program. The Town must consider the following
groups and the SWMP shall provide justification for any listed group not included in
the program:
1) Residents;
2) Visitors;
3) Public Employees;
4) Commercial and Industrial Facilities; and
5) Construction Site Personnel.
The outreach must inform the public about the impacts that pollution in stormwater
run-off can have on water quality, hazards associated with illegal discharges and
improper disposal of waste, and ways they can minimize their impact on stormwater
quality.
(b) The Town of Hickory Creek 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 the General Permit.
TPDES Phase II MS4 General Permit
Stormwater Management Program
Town of Hickory Creek, Texas
June 2014 Page 8
(c) The Town must at a minimum, comply with any state and local public notice
requirements when implementing a public involvement / participation program. The
program may be developed to include opportunities for a wide variety of constituents
within the MS4 area to participate in the SWMP development and implementation.
The Town of Hickory Creek has effectively communicated with the residents through
publication on the Hickory Creek Newsletter. The town shall publish the public notices
through the Denton Record Chronicle and Hickory Creek Newsletter.
The Texas Government Code Chapter 2051, Section 44 defines the requirements for a
newspaper in which a public notice will be published as:
(1) The newspaper in which a notice is published must:
i. devote not less than 25 percent of its total column lineage to general interest
items;
ii. be published at least once each week;
iii. be entered as second-class postal matter in the county where published; and
iv. have been published regularly and continuously for at least 12 months before
the governmental entity or representative publishes notice.
(2) A weekly newspaper has been published regularly and continuously under
Subsection (a) if the newspaper omits not more than two issues in the 12-month
period.
Public meetings, if required, will be conducted according to the Texas Government Code Title 5,
Subtitle A, Chapter 551.

Helpful
Suggestions
The EPA, and TCEQ, have stormwater educational information available
for municipalities to use with minor modifications. Also, to reduce costs
and resource commitments, it is possible to develop materials with other
local Phase II MS4’s or NCTOG municipalities and share printing and
distribution costs.
To meet permit requirements, ensure message targets specific areas of
concern, for example consider targeting the stormwater pollution-
potential of over fertilizing yards and proper disposal of waste for
residences and visitors.

3.3 MCM2 Illicit Discharge Detection and Elimination
The Town of Hickory Creek recognizes the potential for illicit discharges to the Town’s
stormwater system and is committed to addressing these discharges. The BMPs in this section
are targeted toward known and potential illicit discharges.
Non-stormwater discharges will be addressed on a case-by-case basis. Allowable non-
stormwater discharges, as identified in Part II. C of the TPDES General Permit, are not required
to be addressed by the minimum control measures unless they are determined by the Town or
TCEQ to be significant contributors of pollutants to the small MS4. The town of Hickory Creek
will not be sampling stormwater unless illicit discharges are identified
General Permit Requirements
(a) Illicit Discharges
A section within the SWMP must be developed to establish a program to detect and
eliminate illicit discharges to the 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:
(i) Detection
The SWMP must list techniques used for detecting illicit discharges; and
(ii) 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. Where the permittee lacks the authority to develop ordinances or to
implement enforcement actions, the information regarding the illicit discharge may be
referred to the TCEQ’s regional field office.
(b) Allowable Non-Stormwater Discharges
Non-stormwater flows listed in Part II.C and Part VI.B of the General Permit do not need
to be considered by the Town as an illicit discharge requiring elimination unless the
Town or TCEQ identifies the flow as a significant source of pollutants to the MS4. In lieu
of considering non-stormwater sources on a case-by-case basis, the MS4 operator may
develop a list of common and incidental non-stormwater discharges that will not need to
be addressed as illicit discharges requiring elimination. If developed, the listed sources
of pollutants must not be reasonably expected to be significant sources of pollutants
either because of the nature of the discharge or the conditions that have been
established by the Town prior to accepting discharge to the MS4. All local controls and
conditions established for these discharges must be described in the SWMP and any
changes from the initial SWMP must be included in the annual report described in Part
IV.B.2 of the General Permit.

3.4 MCM3 Construction Site Runoff Controls
In the absence of proper management, construction sites can release significant amounts of
sediment into stormwater and eventually into a municipality’s stormwater drainage system.
Other construction site activities such as storage and handling of construction materials also
can release pollutants into the storm drain system. In addition, increases in compaction and
impervious surfaces at construction sites impact stormwater. The fact that construction and
construction-related activities are occurring in the metropolitan area is cause to evaluate the
methods and procedures currently in place to address stormwater runoff. Pollutants from
construction sites that may impact stormwater runoff include sediment, solid and sanitary
wastes, fertilizer, pesticides, oil and grease, truck washout debris, and construction debris.
The Town of Hickory Creek currently has institutional controls related to stormwater at
construction sites. The continued implementation and enforcement of these stormwater runoff
controls will be an important element in Hickory Creek’s Stormwater Management Program. The
town of Hickory Creek will not be sampling the stormwater during the permit period.
General Permit Requirements:
The Town, to the extent allowable under State and local law, must develop, implement,
and enforce a program to reduce pollutants in any stormwater runoff to the MS4 from
construction activities that result in land disturbances 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 Town 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 based on 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 Town 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.

3.5 MCM4 Post-Construction Stormwater Management in New Development and
Redevelopment
There generally are two forms of substantial impacts from post-construction runoff. The first is
caused by an increase in the type and quantity of pollutants in stormwater runoff. As runoff
flows over areas altered by development, it picks up harmful sediment and chemicals such as
oil and grease, pesticides, heavy metals, and nutrients (e.g., nitrogen and phosphorus). These
pollutants become suspended in stormwater runoff and have the ability to impact the food chain
and eventually impact humans. The second kind of post-construction runoff impact occurs by
increasing the quantity of water delivered to the receiving water body during storms. Increased
impervious surfaces interrupt the natural cycle of gradual percolation of water through
vegetation and soil. Instead, water is collected from surfaces such as asphalt and concrete and
routed to drainage systems where large volumes of runoff quickly flow to the nearest receiving
water. This can result in scouring of natural drainage pathways and flooding of areas resulting
in property damage.
General Permit Requirements:
To the extent allowable under State and local law, the Town must develop, implement,
and enforce a program to address stormwater 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 disturbances of one or more acres, that discharge to the 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.

plans, contracts, building permits, a public notice or hearing, zoning requests, or other similar
documentation and activities.
Construction Activity - Soil disturbance, including clearing, grading, and excavating; and not
including routine maintenance that is performed to maintain the original line and grade,
hydraulic capacity, or original purpose of the site (e.g., the routine grading of existing dirt roads,
asphalt overlays of existing roads, the routine clearing of existing right-of-ways, and similar
maintenance activities). Regulated construction activity is defined in terms of small and large
construction activity.
Small Construction Activity is construction activity that results in land disturbance of
equal to or greater than one (1) acre and less than five (5) acres of land. Small construction
activity also includes the disturbance of less than one (1) acre of total land area that is part
of a larger common plan of development or sale if the larger common plan will ultimately
disturb equal to or greater than one (1) and less than five (5) acres of land.
Large Construction Activity is construction activity that results in land disturbance of
equal to or greater than five (5) acres of land. Large construction activity also includes the
disturbance of less than five (5) acres of total land area that is part of a larger common plan
of development or sale if the larger common plan will ultimately disturb equal to or greater
than five (5) acres of land.
Construction Site Operator - The entity or entities associated with a small or large
construction project that meet(s) either of the following two criteria:

portion of an arcuate belt of porous, water-bearing, predominantly carbonate rocks known as
the Edwards and Associated Limestones in the Balcones Fault Zone trending from west to east
to northeast in Kinney, Uvalde, Medina, Bexar, Comal, Hays, Travis, and Williamson Counties;
and composed of the Salmon Peak Limestone, McKnight Formation, West Nueces Formation,
Devil’s River Limestone, Person Formation, Kainer Formation, Edwards Formation, and
Georgetown Formation. The permeable aquifer units generally overlie the less-permeable Glen
Rose Formation to the south, overlie the less-permeable Comanche Peak and Walnut
Formations north of the Colorado River, and underlie the less-permeable Del Rio Clay
regionally.
Edwards Aquifer Recharge Zone - Generally, that area where the stratigraphic units
constituting the Edwards Aquifer crop out, including the outcrops of other geologic formations
in proximity to the Edwards Aquifer, where caves, sinkholes, faults, fractures, or other
permeable features would create a potential for recharge of surface waters into the Edwards
Aquifer. The recharge zone is identified as that area designated as such on official maps located
in the offices of the TCEQ or the TCEQ website.
Final Stabilization - A construction site where any of the following conditions are met:
(a) All soil disturbing activities at the site have been completed and a uniform (for
example, evenly distributed, without large bare areas) perennial vegetative cover with a
density of 70 percent of the native background vegetative cover for the area has been
established on all unpaved areas and areas not covered by permanent structures, or
equivalent permanent stabilization measures (such as the use of riprap, gabions, or
geotextiles) have been employed.
(b) For individual lots in a residential construction site by either:
(1) The homebuilder completing final stabilization as specified in condition (a) above;
or
(2) The homebuilder establishing temporary stabilization for an individual lot prior to
the time of transfer of the ownership of the home to the buyer and after informing
the homeowner of the need for, and benefits of, final stabilization.
(c) For construction activities on land used for agricultural purposes (for example
pipelines across crop or range land), final stabilization may be accomplished by
returning the disturbed land to its preconstruction agricultural use. Areas disturbed
that were not previously used for agricultural activities, such as buffer strips
immediately adjacent to a surface water and areas which are not being returned to their
preconstruction agricultural use must meet the final stabilization conditions of
condition (a) above.
Small MS4 General Permit TPDES General Permit TXR040000 Part I
Page 7
(d) In arid, semi-arid, and drought-stricken areas only, all soil disturbing activities at the
site have been completed and both of the following criteria have been met:

stormwater pollutants. These facilities must include, at a minimum, the MS4 operator’s
maintenance yards, hazardous waste facilities, fuel storage locations, and other facilities where
chemicals or other materials have a high potential to be discharged in stormwater. Among the
factors that must be considered when giving a facility a high priority ranking are: the amount of
urban pollutants stored at the site, the identification of improperly stored materials, activities
that must not be performed outside (for example, changing automotive fluids, vehicle washing),
proximity to waterbodies, proximity to sensitive aquifer recharge features, poor housekeeping
practices, and discharge of pollutant(s) of concern to impaired water(s).
Hyperchlorinated Water – Water resulting from hyperchlorination of waterlines or vessels,
with a chlorine concentration greater than 10 milligrams per liter (mg/L).
Illicit Connection - Any man-made conveyance connecting an illicit discharge directly to a
municipal separate storm sewer.

Part II. Permit Applicability and Coverage
This general permit provides authorization for stormwater and certain non-stormwater
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.
Section A. Small MS4s Eligible for Authorization under this General Permit
Discharges from a small MS4 must be authorized if any of the following criteria are met and
may be authorized under this general permit if coverage is not otherwise prohibited.
1. Small MS4s Located in an Urbanized Area
Operators of small MS4s that are fully or partially located within an urbanized area (UA), as
determined by the 2000 or 2010 Decennial Census by the U.S. Bureau of Census, must
obtain authorization for the discharge of stormwater runoff and are eligible for coverage
under this general permit unless otherwise prohibited.
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 § 122.32(a)(2) or 40 CFR § 122.26(a)(1)(v) and
adopted by reference in Title 30, TAC § 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 stormwater permit
within 180 days of notification of their designation.
3. Operators of Previously Permitted Small MS4s
Operators of small MS4s that were covered under the previous TPDES general permit for
small MS4s (TXR040000, Issued and Effective on August 13, 2007) must reapply for permit
coverage, or must obtain a waiver if applicable (see Part II.B, related to Obtaining a Waiver.)
Small MS4 General Permit TPDES General Permit TXR040000 Part II, Section B
Page 12
4. Regulated Portion of Small MS4
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 UA as defined and used by the U.S. Census
Bureau in the 2000 or 2010 census, as well as any portion of the small MS4 that is
designated by TCEQ.
For the purpose of this permit, the regulated portion of a small MS4 for a transportation
entity is the land owned by the permittee within the UA which functions as, or is integral to
a transportation system with drainage conveyance. Non-contiguous property that does not
drain into the transportation drainage system is not subject to this general permit.
5. Categories of Regulated Small MS4s
This permit defines MS4 operators by the following categories, or levels, based on the
population served within the 2010 UA. The level of a small MS4 may change during the
permit term based on the MS4 operator acquiring or giving up regulated area, such as by
annexing land or if land is annexed away. However, the level of a small MS4 will not change
during the permit term based on population fluctuation.
(a) Level 1: Operators of traditional small MS4s that serve a population of less than 10,000
within a UA;
(b) Level 2: Operators of traditional small MS4s that serve a population of at least 10,000
but less than 40,000 within a UA. This category also includes all non-traditional small
MS4s such as counties, drainage districts, transportation entities, military bases,
universities, colleges, correctional institutions, municipal utility districts and other
special districts regardless of population served within the UA, unless the non-
traditional MS4 can demonstrate that it meets the criteria for a waiver from permit
coverage based on the population served;
(c) Level 3: Operators of traditional small MS4s that serve a population of at least 40,000
but less than 100,000 within a UA;
(d) Level 4: Operators of traditional small MS4s that serve a population of 100,000 or
more within a UA.
For the purpose of this section “serve a population” means the residential population within
the regulated portion of the small MS4 based on the 2010 census, except for non-traditional
small MS4s listed in (b) above.
Section B. Available Waivers from Coverage
The TCEQ may waive permitting requirements for small regulated MS4 operators if the
criteria are met for Waiver Option 1 or 2 below. 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 30 days after an administratively complete 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 technically complete and approve 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.
Small MS4 General Permit TPDES General Permit TXR040000 Part II, Section B
Page 13
If the conditions of a 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.
At any time the TCEQ may 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.
At any time the TCEQ can request to review any waivers granted to MS4 operators to
determine whether any of the information required for granting the waiver has changed. At
a minimum TCEQ will review all waivers when MS4 operators submit their renewal waiver
applications.
For the purpose of obtaining a waiver, the population served refers to the residential
population for traditional small MS4s and for certain non-traditional small MS4s with a
residential population (such as counties and municipal utility districts). For other non-
traditional small MS4s, the population served refers to the number of people using the small
MS4 on an average operational day.
1. Waiver Option 1:
The small MS4 serves a population of less than 1,000 within a UA and meets the following
criteria:
(a) The small MS4 is not contributing substantially to the pollutant loadings of a physically
interconnected MS4 that is regulated by the NPDES / TPDES stormwater program (40
CFR § 122.32(d)); and
(b) If the small MS4 discharges any pollutant(s) that have been identified as a cause of
impairment of any water body to which the small MS4 discharges, stormwater controls
are not needed based on wasteload allocations that are part of an EPA approved or
established TMDL that addresses the pollutant(s) of concern.
2. Waiver Option 2:
The small MS4 serves a population under 10,000 within a UA and meets the following
criteria:
(a) The TCEQ has evaluated all waters of the U.S., 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 stormwater 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.
(d) For the purpose of this paragraph (2.), the pollutant(s) of concern include biochemical
oxygen demand (BOD), sediment or a parameter that addresses sediment (such as total
Small MS4 General Permit TPDES General Permit TXR040000 Part II, Section C
Page 14
suspended solids, turbidity or siltation), pathogens, oil and grease, and any pollutant
that has been identified as a cause of impairment of any water body that will receive a
discharge from the small MS4.
Section C. Allowable Non-Stormwater Discharges
The following non-stormwater 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, or they are otherwise prohibited by
the MS4 operator:
1. Water line flushing (excluding discharges of hyperchlorinated 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 that do not violate Texas Surface Water Quality
Standards;
4. Diverted stream flows;
5. Rising ground waters and springs;
6. Uncontaminated ground water infiltration;
7. Uncontaminated pumped ground water;

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 that do not violate Texas Surface Water
Quality Standards;
14. Street wash water excluding street sweeper waste water;
15. Discharges or flows from emergency 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);
16. Other allowable non-stormwater discharges listed in 40 CFR § 122.26(d)(2)(iv)(B)(1);
17. Non-stormwater discharges that are specifically listed in the TPDES Multi Sector
General Permit (MSGP) TXR050000 or the TPDES Construction General Permit
(CGP) TXR150000;
18. Discharges that are authorized by a TPDES or NPDES permit or that are not required
to be permitted; and
19. Other similar occasional incidental non-stormwater discharges such as spray park
water, unless the TCEQ develops permits or regulations addressing these discharges.
Small MS4 General Permit TPDES General Permit TXR040000 Part II, Section D
Page 15
Section D. 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 TAC Chapter 205 considerations and
requirements, or other site-specific considerations.
2. Discharges of Stormwater Mixed with Non-Stormwater
Stormwater discharges that combine with sources of non-stormwater are not eligible for
coverage by this general permit, unless either the non-stormwater source is described in
Part II.C of this general permit or the non-stormwater source is authorized under a separate
TPDES permit.
3. Compliance with Water Quality Standards
Discharges to surface water in the state that would cause, has the reasonable potential to
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
except as described in Part II.D.4 below. 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 has the
reasonable potential to cause, or contribute to, a violation of water quality standards or is
found to cause, have the reasonable potential 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 based on factors described in Part II.F.2.
4. Impaired Water Bodies and Total Maximum Daily Load (TMDL)
Requirements
Discharges of the pollutant(s) of concern to impaired water bodies for which there is a
TCEQ and EPA approved total maximum daily load (TMDL) are not eligible for this general
permit unless they are consistent with the approved TMDL. A water body is impaired for
purposes of the permit if it has been identified, pursuant to the latest TCEQ and EPA
approved CWA §303(d) list, as not meeting Texas Surface Water Quality Standards.
The permittee shall control the discharges of pollutant(s) of concern to impaired waters and
waters with approved TMDLs as provided in sections (a) and (b) below, and shall assess the
progress in controlling those pollutants.
(a) Discharges to Water Quality Impaired Water Bodies with an Approved TMDL
Small MS4 General Permit TPDES General Permit TXR040000 Part II, Section D
Page 16
If the small MS4 discharges to an impaired water body with an approved TMDL, where
stormwater has the potential to cause or contribute to the impairment, the permittee
shall include in the SWMP controls targeting the pollutant(s) of concern along with any
additional or modified controls required in the TMDL and this section.
The SWMP and required annual reports must include information on implementing
any targeted controls required to reduce the pollutant(s) of concern as described below:
(1) Targeted Controls
The SWMP must include a detailed description of all targeted controls to be
implemented, such as identifying areas of focused effort or implementing
additional Best Management Practices (BMPs) to reduce the pollutant(s) of
concern in the impaired waters.
(2) Measurable Goals
For each targeted control, the SWMP must include a measurable goal and an
implementation schedule describing BMPs to be implemented during each year of
the permit term.
(3) Identification of Benchmarks
The SWMP must identify a benchmark for the pollutant(s) of concern.
Benchmarks are designed to assist in determining if the BMPs established are
effective in addressing the pollutant(s) of concern in stormwater discharge(s) from
the MS4 to the maximum extent practicable (MEP). The BMPs addressing the
pollutant of concern must be re-evaluated on an annual basis for progress towards
the benchmarks and modified as necessary within an adaptive management
framework. These benchmarks are not numeric effluent limitations or permit
conditions but intended to be guidelines for evaluating progress towards reducing
pollutant discharges consistent with the benchmarks. The exceedance of a
benchmark is not a permit violation and does not in itself indicate a violation of
instream water quality standards.
The benchmark must be determined based on one of the following options:
a. If the MS4 is subject to a TMDL that identifies a Waste Load Allocation(s)
(WLA) for permitted MS4 stormwater sources, then the SWMP may identify it
as the benchmark. Where an aggregate allocation is used as a benchmark, all
affected MS4 operators are jointly responsible for progress in meeting the
benchmark and shall (jointly or individually) develop a
monitoring/assessment plan as required in Part II.D.4(a)(6).
b. Alternatively, if multiple small MS4s are discharging into the same impaired
water body with an approved TMDL, with an aggregate WLA for all permitted
stormwater MS4s, then the MS4s may combine or share efforts to determine
an alternative sub-benchmark for the pollutant(s) of concern (e.g., bacteria)
for their respective MS4. The SWMP must clearly define this alternative
approach and must describe how the sub-benchmark would cumulatively
support the aggregate WLA. Where an aggregate benchmark has been broken
into sub-benchmarks for individual MS4s, each permittee is only responsible
for progress in meeting its sub-benchmark.
(4) Annual Report
The annual report must include an analysis of how the selected BMPs will be
effective in contributing to achieving the benchmark.
Small MS4 General Permit TPDES General Permit TXR040000 Part II, Section D
Page 17
(5) Impairment for Bacteria
If the pollutant of concern is bacteria, the permittee shall include focused BMPs
addressing the below areas, as applicable, in the SWMP and implement as
appropriate. If a TMDL Implementation Plan (I-Plan) is available, the permittee
may refer to the I-Plan for appropriate BMPs. The SWMP and annual report must
include the selected BMPs. Permitees may not exclude BMPs associated with the
minimum control measures required under 40 CFR §122.34 from their list of
proposed BMPs. Proposed BMPs will be reviewed by the executive director during
the NOI and SWMP review and approval process.
The BMPs shall, as appropriate, address the following:
a. Sanitary Sewer Systems
(i) Make improvements to sanitary sewers to reduce overflows;
(ii) Address lift station inadequacies;
(iii) Improve reporting of overflows; and
(iv) Strengthen sanitary sewer use requirements to reduce blockage from fats,
oils, and grease.
b. On-site Sewage Facilities (for entities with appropriate jurisdiction)
(i) Identify and address failing systems; and
(ii) Address inadequate maintenance of On-Site Sewage Facilities (OSSFs).
c. Illicit Discharges and Dumping
Place additional effort to reduce waste sources of bacteria; for example, from
septic systems, grease traps, and grit traps.
d. Animal Sources
Expand existing management programs to identify and target animal sources
such as zoos, pet waste, and horse stables.
e. Residential Education
Increase focus to educate residents on:
(i) Bacteria discharging from a residential site either during runoff events or
directly;
(ii) Fats, oils, and grease clogging sanitary sewer lines and resulting
overflows;
(iii) Decorative ponds; and
(iv) Pet waste.
(6) Monitoring or Assessment of Progress
The permittee shall monitor or assess progress in achieving benchmarks and
determine the effectiveness of BMPs, and shall include documentation of this
monitoring or assessment in the SWMP and annual reports. In addition, the
SWMP must include methods to be used.
a. The permittee may use either of the following methods to evaluate progress
towards the benchmark and improvements in water quality as follows:
Small MS4 General Permit TPDES General Permit TXR040000 Part II, Section D
Page 18
(i) Evaluating Program Implementation Measures
The permittee may evaluate and report progress towards the benchmark
by describing the activities and BMPs implemented, by identifying the
appropriateness of the identified BMPs, and by evaluating the success of
implementing the measurable goals.
The permittee may assess progress by using program implementation
indicators such as: (1) number of sources identified or eliminated; (2)
decrease in number of illegal dumping; (3) increase in illegal dumping
reporting; (4) number of educational opportunities conducted; (5)
reductions in sanitary sewer flows (SSOs); or, (6) increase in illegal
discharge detection through dry screening, etc.; or
(ii) Assessing Improvements in Water Quality
The permittee may assess improvements in water quality by using
available data for segment and assessment units of water bodies from
other reliable sources, or by proposing and justifying a different approach
such as collecting additional instream or outfall monitoring data, etc. Data
may be acquired from TCEQ, local river authorities, partnerships, and/or
other local efforts as appropriate.
b. Progress towards achieving the benchmark shall be reported in the annual
report. Annual reports shall report the benchmark and the year(s) during the
permit term that the MS4 conducted additional sampling or other assessment
activities.
(7) Observing no Progress Towards the Benchmark
If, by the end of the third year from the effective date of the permit, the permittee
observes no progress toward the benchmark either from program implementation
or water quality assessments as described in Part II.D.4(a)(6), the permittee shall
identify alternative focused BMPs that address new or increased efforts towards
the benchmark or, as appropriate, shall develop a new approach to identify the
most significant sources of the pollutant(s) of concern and shall develop alternative
focused BMPs for those (this may also include information that identifies issues
beyond the MS4’s control). These revised BMPs must be included in the SWMP
and subsequent annual reports.
Where the permittee originally used a benchmark based on an aggregated WLA,
the permittee may combine or share efforts with other MS4s discharging to the
same watershed to determine an alternative sub-benchmark for the pollutant(s) of
concern for their respective MS4s, as described in Part II.D.4(a)(3)(b) above.
Permittees must document, in their SWMP for the next permit term, the proposed
schedule for the development and subsequent adoption of alternative sub
benchmark for the pollutant(s) of concern for their respective MS4s and associated
assessment of progress in meeting those individual benchmarks.
(b) Discharges Directly to Water Quality Impaired Water Bodies without an Approved
TMDL
The permittee shall also determine whether the permitted discharge is directly to one
or more water quality impaired water bodies where a TMDL has not yet been approved
by TCEQ and EPA. If the permittee discharges directly into an impaired water body
without an approved TMDL, the permittee shall perform the following activities:
Small MS4 General Permit TPDES General Permit TXR040000 Part II, Section D
Page 19
(1) Discharging a Pollutant of Concern
a. Within the first year following the permit effective date, the permittee shall
determine whether the small MS4 may be a source of the pollutant(s) of
concern by referring to the CWA §303(d) list and then determining if
discharges from the MS4 would be likely to contain the pollutant(s) of concern
at levels of concern.
b. If the permittee determines that the small MS4 may discharge the pollutant(s)
of concern to an impaired water body without an approved TMDL, the
permittee shall, no later than two years following the permit effective date,
ensure that the SWMP includes focused BMPs, along with corresponding
measurable goals, that the permittee will implement, to reduce, the discharge
of pollutant(s) of concern that contribute to the impairment of the water body.
c. In addition, no later than three years following the permit effective date, the
permittee shall submit an NOC to amend the SWMP to include any additional
BMPs to address the pollutant(s) of concern.
(2) Impairment of Bacteria
Where the impairment is for bacteria, the permittee shall identify potential
significant sources and develop and implement focused BMPs for those sources.
The permittee may implement the BMPs listed in Part II.D.4(a)(5) or proposed
alternative BMPs as appropriate.
(3) The annual report must include information on compliance with this section,
including results of any sampling conducted by the permittee.
5. Discharges to the Edwards Aquifer Recharge Zone
Discharges of stormwater from regulated small MS4s, and other non-stormwater
discharges, are not authorized by this general permit where those discharges are prohibited
by 30 TAC Chapter 213 (Edwards Aquifer Rule). 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 TAC 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 (WPAP) under the Edwards Aquifer Rule are in addition to the
requirements of this general permit. BMPs and maintenance schedules for structural
stormwater 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 stormwater
runoff are in addition to the effluent limitation requirements found in Part VI.D. of this
general permit.
The permittee’s agency-approved WPAPs that are required by the Edwards Aquifer Rule
must be referenced in the SWMP. Additional agency-approved WPAPs received after the
SWMP submittal must be recorded in the annual report for each respective permit year. For
discharges originating from the small MS4 permitted area, and located on or within ten
stream miles upstream of the Edwards Aquifer recharge zone, applicants must also submit a
copy of the MS4 NOI to the appropriate TCEQ regional office with each WPAP application
submitted to TCEQ on or after August 13, 2012.

Discharges of stormwater from regulated small MS4s and other non-stormwater discharges
are not authorized by this general permit where prohibited by 30 TAC Chapter 311 (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 §
401.002 of the Texas Local Government Code.
8. Indian Country Lands
Stormwater runoff from small MS4s that occur 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 stormwater require authorization under federal NPDES regulations, authority
for these discharges must be obtained from the U.S. EPA.
9. Endangered Species Act
Discharges that would adversely affect a listed endangered or threatened species or its
critical habitat are not authorized by this permit. Federal requirements related to
endangered species apply to all TPDES permitted discharges, and site-specific controls may
be required to ensure that protection of endangered or threatened species is achieved. If a
permittee has concerns over potential impacts to listed species, the permittee shall contact
TCEQ for additional information prior to submittal of the NOI and SWMP. If adverse
impact is determined after submittal of the NOI and SWMP or after permit issuance, the
permittee shall contact TCEQ immediately to determine corrective action and potential
modification to the MS4’s permit.

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 § 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).
Section E. Obtaining Authorization
1. Application for Coverage
When submitting a notice of intent (NOI) and SWMP, for coverage under this general
permit, as described in Parts II.E.3., II.E.4, and Part III, the applicant must follow the
public notice and availability requirements found in Part II.E.12 of this general permit.
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. 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 or SWMP are incomplete
and deny coverage and require that a new complete NOI and SWMP be submitted, 3)
Approve the NOI and SWMP with revisions and provide a written description of the
required revisions along with any compliance schedule(s), or 4) Deny coverage and provide
a deadline by which the MS4 operator must submit an application for an individual permit.
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.E.12. Denial of coverage under this general
permit is subject to the requirements of 30 TAC § 205.4(c). Application deadlines are as
follows:
(a) Small MS4s Located in a 2010 Urbanized Area (UA) (Newly regulated Small MS4s)
Operators of small MS4s described in Part II.A.1 that were not previously regulated
under the TPDES General Permit TXR040000, shall submit an NOI and SWMP within
180 days following the effective date of this general permit.
(b) Small MS4s Located in a 2000 UA (Previously Regulated Small MS4s)
Operators of small MS4s described in Part II.A.1 that were required to obtain
authorization under the previous TPDES General Permit TXR040000 based on the
2000 UA maps shall submit an NOI and revised SWMP within 180 days following the
effective date of this general permit.
(c) Designated Small MS4s
Following designation, operators of small MS4s described in Part II.A.2 shall submit an
NOI and SWMP, or apply for coverage under an individual TPDES stormwater permit,
within 180 days of being notified in writing by the TCEQ of the need to obtain permit
coverage.
Small MS4 General Permit TPDES General Permit TXR040000 Part II, Section E
Page 22
(d) Individual Permit Alternative
If an operator of a small MS4 described in Part II.A.1. of this general permit elects to
apply for an individual permit, the application must be submitted within 90 days
following the effective date of this general permit.
2. Late Submission of the NOI and SWMP
Operators are not prohibited from submitting an NOI and SWMP after the deadlines
provided. If a late NOI and SWMP are submitted, then this general permit provides
authorization only for discharges that occur after permit coverage is obtained. The TCEQ
reserves the right to take appropriate enforcement actions for any unpermitted discharges.
3. Stormwater Management Program (SWMP)
A SWMP must be developed and submitted with the NOI for eligible discharges that will
reach waters of the U.S., including discharges from the regulated small MS4 to other MS4s
or to privately-owned separate storm sewer systems that subsequently drain to waters of the
U.S., according to the requirements of Part III of this general permit. The SWMP must
include, as appropriate, the months and years in which the permittee will undertake
required actions, including interim milestones and the frequency of the action throughout
the permit term.
New elements in the program must be completely implemented within five years of the
effective date of this general permit, or within five years of being designated for those small
MS4s which are designated following permit issuance. Previously regulated MS4s shall
assess existing program elements set forth in the previous permit, modify as necessary, and
develop and implement new elements, as necessary, to continue reducing the discharge of
pollutants from the MS4 to the MEP.
Changes may be made to the SWMP during the permit term. The TCEQ may notify the
permittee of the need to modify the SWMP to be consistent with the general permit, in
which case the permittee will have 90 days to finalize such changes to the SWMP.
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
submittal of a notice of change (NOC) and receipt of written approval of the NOC from the
TCEQ, except as follows:
(a) The following changes may be implemented without submitting an NOC form. The
changes may be made immediately following revision of the SWMP, and must be
included in the annual report:
(1) Adding components, controls, or requirements to the SWMP; or replacing a BMP
with an equivalent BMP. An equivalent BMP is one that is intended to address the
same concern as the original BMP and is substantially similar in nature to the
original BMP;
(2) Nonsubstantive changes, including:
a. A change in personnel, or a reorganization of departments responsible for
implementing the SWMP;
b. Minor clarifications to the existing BMPs;
c. Correction of typographical errors;

if land is de-annexed.
(b) The permittee may replace a less effective or infeasible BMP specifically identified in
the SWMP with an alternative BMP, (for example, replacing a structural BMP with a
non-structural BMP). Such a change may be implemented within 60 days following
submittal of an NOC form, unless the NOC is denied in writing by TCEQ. 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 how the replacement BMP is expected to achieve the goals of the
previous BMP.

with conditions, or deny the NOI based on whether the NOI and SWMP meet the
requirements of this general permit.
(j) 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.
Section F. 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 a UA or 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 UA, 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
responsibilities must meet the following conditions:
(a) Participants
The SWMP must clearly list the name and permit number for each MS4 operator that
chooses to contributes to development or implementation of the SWMP, and provide
written confirmation that the contributing MS4 operator has agreed to contribute. If a
contributing small MS4 has submitted a NOI and SWMP to TCEQ, but has not yet
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 be included in the SWMP.
(b) Responsibilities
Each permittee is entirely responsible for meeting SWMP requirements within the
boundaries of its small MS4. Where a separate MS4 operator is contributing to
implementation of the SWMP, the SWMP must clearly define each minimum control
measure and the component(s) each entity agrees to implement, within which MS4
area(s) each entity agrees to implement 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 TAC Chapter 305 (relating to
Consolidated Permits). The executive director may require a 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. The executive director shall deny or suspend a facility’s
authorization for disposal under this general permit based on a rating of “unsatisfactory
performer” according to commission rules in 30 TAC §60.3, Use of Compliance History. An
applicant who owns or operates a facility classified as an “unsatisfactory performer” is
Small MS4 General Permit TPDES General Permit TXR040000 Part III, Section A
Page 28
entitled to a hearing before the commission prior to having its coverage denied or
suspended, in accordance with TWC § 26.040(h).
Part III. Stormwater Management Program (SWMP)
To the extent allowable under state and local law, a SWMP must be developed, implemented
and enforced according to the requirements of Part III of this general permit, for stormwater
discharges that reach waters of the U.S., regardless of whether the discharge is conveyed
through a separately operated storm sewer system. The SWMP must be developed,
implemented and enforced to reduce the discharge of pollutants from the small MS4 to the
maximum extent practicable (MEP), to protect water quality, and to satisfy the appropriate
water quality requirements of the CWA and the TWC.
A permittee that implements best management practices consistent with the provisions of their
permit and SWMP constitutes compliance with the standard of reducing pollutants to the MEP
and will be deemed in compliance with Part III of this permit. This permit does not extend any
compliance deadlines set forth in the previous permit effective August 13, 2007.
Section A. Developing a Stormwater Management Program (SWMP)
1. SWMP Development and Schedule
(a) Existing regulated small MS4s
Permittees who were regulated under the previous TPDES general permit
TXR040000, shall update and submit to the TCEQ an updated SWMP under this
general permit along with the NOI for coverage. The NOI and SWMP are due within
180 days of the general permit effective date. The permittee shall continue to operate
under the conditions of the previous permit and existing SWMP until the revised
SWMP is approved.
(b) New regulated small MS4s
Operators of regulated small MS4s that were not required to obtain permit coverage
under the previous TPDES general permit TXR040000, have 180 days from the
effective date of the general permit to develop and submit their NOI and SWMP.
(c) Implementation of the SWMP
Existing small MS4 operators shall ensure full implementation of any new elements in
the revised SWMP as soon as practicable, but no later than five years from the permit
effective date. Previously regulated MS4 operators shall continue to implement
existing elements in the approved SWMPs until the revised SWMPs has been
approved.
Designated small MS4s must achieve full implementation of the SWMP as soon as
practicable, but no later than five years from designation. Newly regulated small
MS4s, based on the 2010 Decennial Census, must achieve full implementation of the
SWMP as soon as practicable, but no later than five years from the permit effective
date.
2. Content of the SWMP
At a minimum, the permittee shall include the following information in its SWMP:

Requirements)
3. Legal Authority
(a) Traditional small MS4s, such as cities
(1) Within two years from the permit effective date, the permittee shall review and
revise, if needed, its relevant ordinance(s) or other regulatory mechanism(s), or
shall adopt a new ordinance(s) or other regulatory mechanism(s) that provide the
permittee with adequate legal authority to control pollutant discharges into and
from its small MS4 in order to meet the requirements of this general permit.
(2) To be considered adequate, this legal authority must, at a minimum, address the
following:
a. Authority to prohibit illicit discharges and illicit connections;
b. Authority to respond to and contain other releases – Control the discharge of
spills, and prohibit dumping or disposal of materials other than stormwater
into the small MS4;
c. Authority to require compliance with conditions in the permittee’s ordinances,
permits, contracts, or orders;
d. Authority to require installation, implementation, and maintenance of control
measures;
e. Authority to receive and collect information, such as stormwater plans,
inspection reports, and other information deemed necessary to assess
compliance with this permit, from operators of construction sites, new or
redeveloped land, and industrial and commercial facilities;

Page 30
(b) Non-traditional small MS4s, such as counties, drainage districts, transportation
entities, municipal utility districts, military bases, prisons and universities
(1) 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, contractors, and any other entity
over which it has operational control within the portion of the UA under the
jurisdiction of the permittee. For discharges from third party actions, the
permittee shall perform inspections and exert enforcement authority to the MEP.
(2) If the permittee does not have inspection or 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 following
actions in order to meet the goals of the permit:
a. 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,
b. If it is not feasible for the permittee to enter into interlocal agreements, the
permittee shall notify an adjacent MS4 operator with enforcement authority or
TCEQs Field Operations Support Division as needed to report discharges or
incidents that it cannot itself enforce against. In determining feasibility for
entering into interlocal agreements, the permittee shall consider all factors,
including, without limitations, financial considerations and the willingness of
the municipalities in which the small MS4 is located.
4. Resources
It is the permittee’s responsibility to ensure that it has adequate resources and funding to
implement the requirements of this permit.
5. Effluent Limitations
The controls and BMPs included in the SWMP constitute effluent limitations for the
purposes of compliance with state rules. This includes the requirements of 30 TAC Chapter
319, Subchapter B, which lists the maximum allowable concentrations of hazardous metals
for discharge to water in the state.
6. Enforcement Measures
Permittees with enforcement authority (i.e. traditional small MS4s) shall develop a standard
operating procedure (SOP) to respond to violations to the extent allowable under state and
local law. When the permittee does not have enforcement authority over the violator, and
the violations continue after violator has been notified by the permittee, the permittee shall
notify either the adjacent MS4 operator with enforcement authority or TCEQ’s Field
Operations Support Division.
Section B. Minimum Control Measures
Operators of small MS4s seeking coverage under this general permit shall develop and
implement a SWMP that includes the following six minimum control measures (MCMs), as
applicable.
Small MS4 General Permit TPDES General Permit TXR040000 Part III, Section B
Page 31
All program elements must be implemented according to the schedule mentioned in Part
III.A. All six MCMs apply to all MS4s regardless of their level as described in Part II.A.5.
Specific program elements under each MCM shall be implemented by all MS4 operators,
unless it is specifically stated that particular program elements only are applicable for
certain levels of small MS4s.
Permittees shall provide justification within the SWMP for any requirements that were not
implemented because they were not feasible as described in each MCM.
1. Public Education, Outreach, and Involvement
(a) Public Education and Outreach
(1) All permittees shall develop, implement, and maintain a comprehensive
stormwater education and outreach program to educate public employees,
businesses, and the general public of hazards associated with the illegal discharges

can have on local waterways, as well as the steps that the public can take to reduce
pollutants in stormwater.
Existing permittees shall assess program elements that were described in the
previous permit, modify as necessary, and develop and implement new elements,
as necessary, to continue reducing the discharge of pollutants from the MS4 to the
MEP. New elements must be fully implemented by the end of this permit term and
newly regulated permittees shall have the program fully implemented by the end of
this permit term. The program must, at a minimum:
a. Define the goals and objectives of the program based on high priority
community-wide issues (for example, reduction of nitrogen in discharges from
the small MS4, promoting previous techniques used in the small MS4, or
improving the quality of discharges to the Edwards Aquifer);
b. Identify the target audience(s);
c. Develop or utilize appropriate educational materials, such as printed
materials, billboard and mass transit advertisements, signage at select
locations, radio advertisements, television advertisements, and websites;

required to implement this portion of the MCM.
Existing permittees shall assess program elements that were described in the previous
permit, modify as necessary, and develop and implement new elements, as necessary,
to continue reducing the discharge of pollutants from the MS4 to the MEP. New
elements must be fully implemented by the end of this permit term and newly
regulated permittees shall have the program fully implemented by the end of this
permit term. At a minimum, all permittees shall:
(1) If feasible, consider using public input (for example, the opportunity for public
comment, or public meetings) in the implementation of the program;
(2) If feasible, create opportunities for citizens to participate in the implementation of
control measures, such as stream clean-ups, storm drain stenciling, volunteer
monitoring, volunteer “Adopt-A-Highway” programs, and educational activities;
(3) Ensure the public can easily find information about the SWMP.
2. Illicit Discharge Detection and Elimination (IDDE)
(a) Program Development
(1) All permittees shall develop, implement and enforce a program to detect,

stormwater controls at all high priority facilities identified in Part III.B.5.(c)(4)b. A
description of BMPs developed to comply with this requirement must be included
in each facility specific SOP:
a. General good housekeeping – Material with a potential to contribute to
stormwater pollution should be sheltered from exposure to stormwater when
feasible.
b. De-icing and anti-icing material storage - The permittee shall ensure, to the
MEP, that stormwater runoff from storage piles of salt and other de-icing and
anti-icing materials is not discharged; or shall ensure that any discharges from
the piles are authorized under a separate discharge permit.
c. Fueling operations and vehicle maintenance - The permittee shall develop
SOPs (or equivalent existing plans or documents) which address spill
prevention and spill control at permittee-owned and operated vehicle fueling,
vehicle maintenance, and bulk fuel delivery facilities.

7. Authorization for Construction Activities where the Small MS4 is the Site
Operator
The development of this MCM for construction activities, where the small MS4 is the site
operator, is optional and provides an alternative to the MS4 operator seeking coverage
under TPDES CGP, TXR150000 for each construction activity. Permittees that choose to
develop this measure will be authorized to discharge stormwater and certain non-
stormwater from construction activities where the MS4 operator meets the definition of a
construction site operator in Part I of this general permit. When developing this measure,
permittees are required to meet all requirements of, and be consistent with, applicable
effluent limitation guidelines for the Construction and Development industry (40 CFR Part
450), TPDES CGP TXR150000, and Part III.B.3 of this permit. The authorization to
discharge under this MCM is limited to the regulated area, such as the portion of the small
MS4 located within a UA or the area designated by TCEQ as requiring coverage. However,
an MS4 operator may also utilize this MCM over additional portions of their small 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 CGP, TXR150000, or under an individual TPDES permit.
This MCM is only available for projects where the small MS4 is a construction site operator
or owner, and the MCM does not provide any authorization for other construction site
operators at a municipal project.
Controls required under this MCM must be implemented prior to discharge from a
municipal construction site into surface water in the state.
(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 (for example within the boundary of the
urbanized area, the corporate boundary, a special district boundary, an extra
territorial jurisdiction, or other similar jurisdictional boundary);
(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 stormwater discharges;
(4) A general description of how a SWP3 will be developed for each construction site,
according to Part VI of this general permit, ”Authorization for Municipal
Construction Activities”; and
(5) Records of municipal construction activities authorized under this optimal MCM,
in accordance with Part VI of this general permit.

implementation of the program. 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. If applicable, a list of all MS4 operators contributing to the development and
implementation of the SWMP, including a clear description of the contribution;
3. A list of all BMPs and measurable goals for each of the MCMs;
4. A schedule for the implementation of all SWMP requirements. The schedule must
include, as appropriate, the months and years in which the permittee will undertake
required actions, including interim milestones and the frequency of the action
throughout the permit term.
5. A description of how each measurable goal will be evaluated; and
6. A rationale statement that addresses the overall program, including how the BMPs and
measurable goals were selected.
Part IV. Recordkeeping and Reporting
Section A. Recordkeeping
1. The permittee shall 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 (3) 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 shall 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 shall make the NOI and the SWMP available to the public at reasonable
times during regular business hours, if requested to do so in writing. Copies of the
SWMP must be made available within ten (10) working days of receipt of a written

optional MCM, including the total number of acres disturbed;
and
(i) The number of construction activities that occurred within the jurisdictional area of the
small MS4 (as noticed to the permittee by the construction operator), and that were not
authorized under the 7
th
MCM.
An annual report must be prepared whether or not the NOI and SWMP have 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.
If permittees share a common SWMP, they shall contribute to and submit a single system-
wide report. Each permittee shall sign and certify the annual report in accordance with 30
TAC § 305.128 (relating to Signatories to Reports).

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, www.tceq.texas.gov 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.
Small MS4 General Permit TPDES General Permit TXR040000 Part V
Page 50
B. It shall not be a defense for the permittee in an enforcement action that it would have
been necessary to halt or reduce the permitted activity in order to maintain compliance
with the conditions of this permit.
C. The permittee shall take all reasonable steps to minimize or prevent any discharge in
violation of this permit which has a reasonable likelihood of adversely affecting human
health or the environment.
D. 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 shall 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 modifying, revoking, suspending,
reissuing or terminating authorization under this general permit. Additionally, the
permittee shall provide to the executive director, upon request, copies of all records
that the permittee shall maintain as a condition of this general permit.
E. The permittee shall at all times properly operate and maintain all facilities and systems
of treatment and control (and related appurtenances) which are installed or used to
achieve compliance with the conditions of this permit and with the condition of the
permittee’s SWMP. Proper operation and maintenance also includes adequate
laboratory controls and appropriate quality assurance procedures. Proper operation
and maintenance requires the operation of backup or auxiliary facilities or similar
systems, installed only when the operation is necessary to achieve compliance with the
conditions of this permit.
F. Inspection and entry shall be allowed under the TWC Chapters 26-28, Health and
Safety Code §§ 361.032-361.033 and 361.037, and 40 CFR §122.41(i). The statement in
TWC § 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.
G. The discharger is subject to administrative, civil, and criminal penalties, as applicable,
under the TWC, Chapters 26, 27, and 28, and the Texas Health and Safety Code,
Chapter 361 for violations including but not limited to the following:
1. Negligently or knowingly violating CWA, §§ 301, 302, 303, 306, 307, 308, 318, or
405, or any condition or limitation implementing any sections in a permit issued
under CWA, § 402; and
2. 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.
H. All reports and other information requested by or submitted to the executive director
must be signed by the person and in the manner required by 30 TAC § 305.128
(relating to Signatories to Reports).
I. Authorization under this general permit does not convey property or water rights of
any sort and does not grant any exclusive privilege.
Small MS4 General Permit TPDES General Permit TXR040000 Part VI, Section A & B
Page 51
J. The permittee shall implement its SWMP on any new areas under its jurisdiction that
are located in a UA or that are designated by the TCEQ. Implementation of the SWMP
in these areas is required the greater of three (3) years from acquiring the new area, or
five (5) years from the date of initial permit coverage.
Part VI. Authorization for Municipal Construction Activities – Applicable only
if the 7th Optional MCM is selected
The MS4 operator may obtain authorization under TPDES CGP, TXR150000 to discharge
stormwater runoff from each construction activity performed by the MS4 operator that results
in a land disturbance of one (1) acre or more of land or less than one (1) acre of land, if the
construction activity is part of a larger common plan of development or sale that would disturb
one acre or more. Alternatively, the MS4 operator may develop the SWMP to include the
optional seventh (7
th
) stormwater MCM listed in Part III.B.7 of this general permit if the
eligibility requirements in Part VI.A. below are met. If an MS4 operator decides to utilize this
MCM, then the MS4 operator must include this MCM 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 permittee 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
small 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 stormwater MCM, the MS4
operator may apply under TPDES CGP 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).
Section 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 III.B.1. through III.B.6 of this general permit, related to MCMs.
Section B. Discharges Eligible for Authorization
1. Stormwater Associated with Construction Activity
Discharges of stormwater runoff from small and large construction activities may be
authorized under this general permit.
2. Discharges of Stormwater Associated with Construction Support Activities

complies with the associated permit.
Small MS4 General Permit TPDES General Permit TXR040000 Part VI, Section C, D & E
Page 53
Section C. Limitations on Permit Coverage
Discharges that occur after construction activities have been completed, and after the
construction site and any supporting activity site have undergone final stabilization, are not
eligible for coverage under Part VI of the general permit.
Section D. Stormwater Pollution Prevention Plan (SWP3) Requirements
Operators of municipal construction activities that qualify for coverage under this general
permit and that discharge stormwater associated with construction activities into surface
water in the state 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 a TCEQ approved site notice 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 project 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.
Section E. Stormwater Runoff from Concrete Batch Plants
Discharges of stormwater runoff from concrete batch plants at regulated construction sites
may be authorized under the provisions of this general permit provided that the following
requirements are met for concrete batch plant(s) authorized under this permit. If discharges
of stormwater runoff from concrete batch plants are not covered under this general permit,
then discharges must be authorized under an alternative general permit or an individual
permit. This permit does not authorize the discharge or land disposal of any wastewater
from concrete batch plants at regulated construction sites. Authorization for these wastes
must be obtained under an individual permit or an alternative general permit.
1. Benchmark Sampling Requirements
(a) Operators of concrete batch plants authorized under this section must sample the
stormwater runoff from the concrete batch plants according to the requirements of this
section of the general permit, and must conduct evaluations of the effectiveness of the
SWP3 based on the following benchmark monitoring values:

discharge. If it is not practicable to take the sample, or to complete the
sampling, within the first 30 minutes, sampling must be completed within the
first hour of discharge. If sampling is not completed within the first 30
minutes of discharge, the reason must be documented and attached to all
required reports and records of the sampling activity.
(*2) Sampling must be conducted at least once during each of the following
periods. The first sample must be collected during the first full quarter that a
stormwater discharge occurs from a concrete batch plant authorized under
this general permit.
January through March
April through June
July through September
October through December
For projects lasting less than one full quarter, a minimum of one sample shall
be collected, provided that a stormwater discharge occurred at least once
following submission of the NOI.
(*3) A grab sample shall be collected from the stormwater discharge resulting
from a storm event that is at least 0.1 inches of measured precipitation that
occurs at least 72 hours from the previously measurable storm event. The
sample shall be collected downstream of the concrete batch plant, and where
the discharge exits any BMPs utilized to handle the runoff from the batch
plant, prior to commingling with any other water authorized under this
general permit.
(b) The permittee shall compare the results of sample analyses to the benchmark values
above, and must include this comparison in the overall assessment of the SWP3’s
effectiveness. Analytical results that exceed a benchmark value are not a violation of
this permit, as these values are not numeric effluent limitations. Results of analyses are
indicators that modifications of the SWP3 should be assessed and may be necessary to
protect water quality. The operator must investigate the cause for each exceedance and
must document the results of this investigation in the SWP3 by the end of the quarter
following the sampling event.
The operator’s investigation must identify the following:
(1) Any additional potential sources of pollution, such as spills that might have
occurred;
(2) Necessary revisions to good housekeeping measures that are part of the SWP3;
(3) Additional BMPs, including a schedule to install or implement the BMPs; and
Small MS4 General Permit TPDES General Permit TXR040000 Part VI, Section E
Page 55
(4) Other parts of the SWP3 that may require revisions in order to meet the goal of the
benchmark values.
Background concentrations of specific pollutants may also be considered during the
investigation. If the operator is able to relate the cause of the exceedance to background
concentrations, then subsequent exceedances of benchmark values for that pollutant
may be resolved by referencing earlier findings in the SWP3. Background
concentrations may be identified by laboratory analyses of samples of stormwater run-
on to the permitted facility, by laboratory analyses of samples of stormwater run-off
from adjacent non-industrial areas, or by identifying the pollutant is a naturally
occurring material in soils at the site.

available to the appropriate personnel.
(3) Inspections - Qualified facility personnel (for example, a person or persons with
knowledge of this general permit, the concrete batch plant, and the SWP3 related
to the concrete batch plant(s) for the site) must be identified to inspect designated
equipment and areas of the facility specified in the SWP3. The inspection
frequency must be specified in the SWP3 based upon a consideration of the level of
concrete production at the facility, but must be a minimum of once per month
while the facility is in operation. The inspection must take place while the facility is
in operation and must, at a minimum, include all areas that are exposed to
stormwater at the site, including material handling areas, above ground storage
tanks, hoppers or silos, dust collection or containment systems, truck wash down
and equipment cleaning areas. Follow-up procedures must be used to ensure that
appropriate actions are taken in response to the inspections. Records of
inspections must be maintained and be made readily available for inspection upon
request.
(4) Employee Training - An employee training program must be developed to educate
personnel responsible for implementing any component of the SWP3, or personnel
otherwise responsible for stormwater pollution prevention, with the provisions of
the SWP3. The frequency of training must be documented in the SWP3, and at a
Small MS4 General Permit TPDES General Permit TXR040000 Part VI, Section E
Page 57
minimum, must consist of one training prior to the initiation of operation of the
concrete batch plant.
(5) Record Keeping and Internal Reporting Procedures - A description of spills and
similar incidents, plus additional information that is obtained regarding the
quality and quantity of stormwater discharges, must be included in the SWP3.
Inspection and maintenance activities must be documented and records of those
inspection and maintenance activities must be incorporated in the SWP3.
(6) Management of Runoff - The SWP3 shall contain a narrative consideration for
reducing the volume of runoff from concrete batch plants by diverting runoff or
otherwise managing runoff, including use of infiltration, detention ponds,
retention ponds, or reusing of runoff.
(c) Comprehensive Compliance Evaluation – At least once per year, one (1) or more
qualified personnel (for example, a person or persons with knowledge of this general
permit, the concrete batch plant, and the SWP3 related to the concrete batch plant(s)
for the site) shall conduct a compliance evaluation of the plant. The evaluation must
include the following:
(1) Visual examination of all areas draining stormwater associated with regulated
concrete batch plants for evidence of, or the potential for, pollutants entering the
drainage system. These include but are not limited to: cleaning areas, material
handling areas, above ground storage tanks, hoppers or silos, dust collection or
containment systems, and truck wash down and equipment cleaning areas.
Measures implemented to reduce pollutants in runoff (including structural
controls and implementation of management practices) must be evaluated to
determine if they are effective and if they are implemented in accordance with the
terms of this permit and with the permittee’s SWP3. The operator shall conduct a
visual inspection of equipment needed to implement the SWP3, such as spill
response equipment.
(2) Based on the results of the evaluation, the following must be revised as appropriate
within two (2) weeks of the evaluation: the description of potential pollutant
sources identified in the SWP3 (as required in Part VI.E.2(a), “Description of
Potential Pollutant Sources”); and pollution prevention measures and controls
identified in the SWP3 (as required in Part VI.E.2.(b) “Measures and Controls”).
The revisions may include a schedule for implementing the necessary changes.
(3) The permittee shall prepare and include in the SWP3 a report summarizing the
scope of the evaluation, the personnel making the evaluation, the date(s) of the
evaluation, major observations relating to the implementation of the SWP3, and
actions taken in response to the findings of the evaluation. The report must
identify any incidents of noncompliance. Where the report does not identify
incidences of noncompliance, the report must contain a statement that the
evaluation did not identify any incidence(s), and the report must be signed
according to 30 TAC Section 305.128, relating to Signatories to Reports.
(4) The Comprehensive Compliance Evaluation may substitute for one of the required
inspections delineated in Part VI.E.2.(b)(3) of this general permit.
3. Prohibition of Wastewater Discharges
Wastewater discharges associated with concrete production including wastewater disposal
by land application are not authorized under this general permit. These wastewater
Small MS4 General Permit TPDES General Permit TXR040000 Part VI, Section F&G
Page 58
discharges must be authorized under an alternative TCEQ water quality permit or otherwise
disposed of in an authorized manner. Discharges of concrete truck washout at construction
sites may be authorized if conducted in accordance with the requirements of Part VI of this
general permit.
4. Concrete Truck Wash Out Requirements
This general permit authorizes the wash out of concrete trucks at construction sites
regulated under this section of the general permit, provided the following requirements are
met. Authorization is limited to the land disposal of wash out water from concrete trucks.
Any other direct discharge of concrete production waste water must be authorized under a
separate TCEQ general permit or individual permit.
(a) Direct discharge of concrete truck wash out water to surface water in the state,
including discharge to storm sewers, is prohibited by this general permit.
(b) Concrete truck wash out water shall be discharged to areas at the construction site
where structural controls have been established to prevent direct discharge to surface
waters or to areas that have a minimal slope that allow infiltration and filtering of wash
out water to prevent direct discharge to surface waters. Structural controls may consist
of temporary berms, temporary shallow pits, temporary storage tanks with slow rate
release, or other reasonable measures to prevent runoff from the construction site.
(c) Wash out of concrete trucks during rainfall events shall be minimized. The direct
discharge of concrete truck wash out water is prohibited at all times, and the operator
shall insure that its BMPs are sufficient to prevent the discharge of concrete truck
washout as the result of rain.
(d) The discharge of wash out water shall not cause or contribute to groundwater
contamination.
(e) If a SWP3 is required to be implemented, the SWP3 shall include concrete wash out
areas on the associated map.
Section F. Effective Date of Coverage
Construction activities may not commence under this section until the MS4 NOI and SWMP
are approved in writing by the TCEQ. Following approval of the NOI and SWMP, operators
of construction activities eligible for coverage under this general permit are authorized to
discharge stormwater associated with construction activity immediately upon posting the
signed construction site notice required under this section.
Section 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.
Small MS4 General Permit TPDES General Permit TXR040000 Part VI, Section H, I & J
Page 59
Section 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 stormwater management plans;
and to local government officials.
Section I. Keeping Plans Current
The permittee shall amend the SWP3 whenever either of the following occurs:
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 SWP3; 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.
Section J. Contents of SWP3
The SWP3 must include, at a minimum, the information described in this section.
1. Site Description
A site description, or project description, which must include:
(a) A description of the nature of the construction activity, potential pollutants and
sources;
(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

(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. Structural and non-structural controls
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:
(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 per cent.
(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 stormwater 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 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
Small MS4 General Permit TPDES General Permit TXR040000 Part VI, Section J
Page 61
(3) The dates when stabilization measures are initiated.
(c) Stabilization measures must be initiated immediately in portions of the site where
construction activities have temporarily or permanently ceased, and will not resume for
a period exceeding 14 calendar days, except as provided in (1) and (2) below.
(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, semiarid areas, and areas experiencing drought
conditions.
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) Sites with a drainage area of ten (10) or more acres:
(1) A sediment basin is required, where feasible, for a common drainage location that
serves an area with ten (10) or more acres disturbed at one time. A sedimentation
basin may be temporary or permanent, but must provide sufficient storage to
contain a calculated volume of runoff from a 2-year, 24-hour storm from each
disturbed 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 off-site areas and
flow from on-site 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. Capacity calculations must be included in the SWP3.
(2) Where rainfall data is not available or a calculation cannot be performed the
sedimentation basin must provide at least 3,600 cubic feet of storage per acre
drained until the site reaches final stabilization.
(3) If a sedimentation basin is not feasible, then the permittee shall provide equivalent
control measures until the site reaches final stabilization. In determining whether
installing a sediment basin is feasible, the permittee may consider factors such as
site soils, slope, available area, public safety, precipitation pattern, site geometry,
site vegetation, infiltration capacity, geotechnical factors, depth to groundwater,
and other similar considerations. The permittee shall document the reason that the
sediment basins are not feasible, and shall utilize equivalent control measures,
which may include a series of smaller sediment basins.
(4) Perimeter Controls – At a minimum, silt fences, vegetative buffer strips, or
equivalent sediment controls are required for all down slope boundaries of the
construction area, and for those side slope boundaries deemed appropriate as
dictated by individual site conditions.
(b) Controls for sites with drainage areas less than ten acres:
(1) Sediment traps and sediment basins may be used to control solids in stormwater
runoff for drainage locations serving less than ten (10) acres. At a minimum, silt
Small MS4 General Permit TPDES General Permit TXR040000 Part VI, Section J
Page 62
fences, vegetative buffer strips, or equivalent sediment controls are required for all
down slope boundaries of the construction area, and for those side slope
boundaries deemed appropriate as dictated by individual site conditions.
(2) Alternatively, a sediment basin that provides storage for a calculated volume of
runoff from a 2-year, 24-hour storm from each disturbed acre drained may be
utilized. Where rainfall data is not available or a calculation cannot be performed,
a temporary or permanent sediment basin providing 3,600 cubic feet of storage
per acre drained may be provided. If a calculation is performed, then the
calculation shall be included in the SWP3.
5. Permanent Stormwater Controls
A description of any measures that will be installed during the construction process to
control pollutants in stormwater 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 stormwater 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 stormwater 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. Effluent Limits
The federal Effluent Limitations Guidelines at 40 CFR Part 450.21(a) apply to all regulated
construction activities under this 7
th
optional MCM, where the small MS4 is the operator.
8. Approved State and Local Plans
(a) The permittee shall ensure the SWP3 is consistent with requirements specified in
applicable sediment and erosion site plans or site permits, or stormwater 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
stormwater management site plans or site permits approved by state or local official for
whom the permittee receives written notice.
9. 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 stormwater controls. If maintenance prior to the next anticipated
Small MS4 General Permit TPDES General Permit TXR040000 Part VI, Section J
Page 63
storm event is impracticable, maintenance must be scheduled and accomplished as soon as
practicable.
10. Inspections of Controls
(a) Personnel provided by the permittee 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, discharge locations, and structural controls for evidence of, or
the potential for, pollutants entering the drainage system. Personnel conducting these
inspections must be knowledgeable of this general permit, familiar with the
construction site, and knowledgeable of the SWP3 for the site. Sediment and erosion
control measures identified in the SWP3 must be inspected to ensure that they are
operating correctly. Locations where vehicles enter or exit the site must be inspected
for evidence of off-site sediment tracking. Inspections must be conducted at least once
every 14 calendar days and within 24 hours of the end of a storm event of 0.5 inches or
greater.
Where sites have been finally or temporarily stabilized or where runoff is unlikely due
to winter conditions (e.g. site is covered with snow, ice, or frozen ground exists),
inspections must be conducted at least once every month. In arid or semi-arid, or
drought stricken areas, inspections must be conducted at least once every month and
within 24 hours after the end of a storm event of 0.5 inches or greater
As an alternative to the above-described inspection schedule of once every 14 calendar
days and within 24 hours of a storm event of 0.5 inches or greater, the SWP3 may be
developed to require that these inspections will occur at least once every seven (7)
calendar days. If this alternative schedule is developed, then the inspection must occur
on a specifically defined day, regardless of whether or not there has been a rainfall
event since the previous inspection. The inspections may occur on either schedule
provided that the SWP3 reflects the current schedule and that any changes to the
schedule are conducted in accordance with the following provisions: the schedule may
be changed a maximum of one time each month, the schedule change must be
implemented at the beginning of a calendar month, and the reason for the schedule
change must be documented in the SWP3 (e.g., end of “dry” season and beginning of
“wet” season).
(b) Utility line installation, pipeline construction, and other examples of long, narrow,
linear construction activities may provide inspection personnel with limited access to
the areas described in Part VI.J.10(a) above. Inspection of these areas could require
that vehicles compromise temporarily or even permanently stabilized areas, cause
additional disturbance of soils, and increase the potential for erosion. In these
circumstances, controls must be inspected at least once every 14 calendar days and
within 24 hours of the end of a storm event of 0.5 inches, but representative
inspections may be performed. For representative inspections, personnel must inspect
controls along the construction site for 0.25 mile above and below each access point
where a roadway, undisturbed right-of-way, or other similar feature intersects the
construction site and allows access to the areas described in Part VI.J.10.(a) above. The
conditions of the controls along each inspected 0.25 mile portion may be considered as
representative of the condition of controls along that reach extending from the end of
the 0.25 mile portion to either the end of the next 0.25 mile inspected portion, or to the
end of the project, whichever occurs first.
As an alternative to the above-described inspection schedule of once every 14 calendar
days and within 24 hours of a storm event of 0.5 inches or greater, the SWP3 may be
Small MS4 General Permit TPDES General Permit TXR040000 Part VI, Section K
Page 64
developed to require that these inspections will occur at least once every seven (7)
calendar days. 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. The inspections may occur on either schedule provided
that the SWP3 reflects the current schedule and that any changes to the schedule are
conducted in accordance with the following provisions: the schedule may be changed a
maximum of one time each month, the schedule change must be implemented at the
beginning of a calendar month, and the reason for the schedule change must be
documented in the SWP3 (e.g., end of “dry” season and beginning of “wet” season).
(c) In the event of flooding or other uncontrollable situations which prohibit access to the
inspection sites, inspections must be conducted as soon as access is practicable.
(d) 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.
(e) A report summarizing the scope of the inspection, the date(s) 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 particular location; and locations where additional BMPs are needed.
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.
The report must be signed by the person and in the manner required by 30 TAC
§305.128 (relating to Signatories to Reports).
(f) The names and qualifications of personnel making the inspections for the permittee
may be documented once in the SWP3 rather than being included in each report.
11. Pollution Prevention Measures
The SWP3 must identify and ensure the implementation of appropriate pollution prevention
measures for all eligible non-stormwater components of the discharge.
Section K. Additional Retention of Records
The permittee shall 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 section, including copies of the construction
site notices.

public meeting at least 30 days prior to the public meeting and hold the meeting in the county
where the MS4 is located.
5. CERTIFICATIONS
Failure to indicate Yes to ALL of the certification items may result in denial of coverage under
the general permit.
Operator Certification:
The certification must bear an original signature of a person meeting the signatory requirements
specified under 30 Texas Administrative Code (TAC) §305.44.
IF YOU ARE A CORPORATION:
The regulation that controls who may sign an NOI or similar form is 30 Texas Administrative
Code §305.44(a)(1) (see below). According to this code provision, any corporate representative
may sign an NOI or similar form so long as the authority to sign such a document has been
delegated to that person in accordance with corporate procedures. By signing the NOI or similar
form, you are certifying that such authority has been delegated to you. The TCEQ may request
documentation evidencing such authority.
IF YOU ARE A MUNICIPALITY OR OTHER GOVERNMENT ENTITY:
The regulation that controls who may sign an NOI or similar form is 30 Texas Administrative
Code §305.44(a)(3) (see below). According to this code provision, only a ranking elected official
or principal executive officer may sign an NOI or similar form. Persons such as the City Mayor
or County Commissioner will be considered ranking elected officials. In order to identify the
principal executive officer of your government entity, it may be beneficial to consult your city
charter, county or city ordinances, or the Texas statute(s) under which your government entity
was formed. An NOI or similar document that is signed by a government official who is not a
ranking elected official or principal executive officer does not conform to §305.44(a)(3). The
signatory requirement may not be delegated to a government representative other than those
identified in the regulation. By signing the NOI or similar form, you are certifying that you are
either a ranking elected official or principal executive officer as required by the administrative
code. Documentation demonstrating your position as a ranking elected official or principal
executive officer may be requested by the TCEQ.
If you have any questions or need additional information concerning the signatory requirements
discussed above, please contact the Texas Commission on Environmental Quality’s

D. Storm Water Management Program Status. Provide the status of every BMP and measurable
goal listed in the SWMP, as described in the instructions. Each MCM, but not necessarily each BMP,
must include the measurable goals described in the SWMP. For a shared SWMP, include the name
of the responsible MS4 operator(s) in the “BMP” column. (Though an MS4 is not required to
implement BMPs until the initial SWMP is approved by the TCEQ, the MS4’s initial annual report
