1.
Dewatering activities shall conform to applicable provisions in 02370.
2.
Provide dewatering systems as required for excavations.
3.
Design and provide dewatering system using accepted and professional methods consistent with current
industry practice to eliminate water entering the excavation under hydrostatic head from the bottom or
sides. Design system to prevent differential hydrostatic head, which would result in floating out soil
particles in a manner, termed as a “quick” or “boiling” condition. System shall not be dependent solely
upon sumps or pumping water from within the excavation where differential head would result in a quick
condition, which would continue to worsen the integrity of the excavation’s stability.
4.
Provide dewatering system of sufficient size and capacity to prevent ground and surface water flow into the
excavation and to allow Work to be installed in a dry condition.
5.
Control, by acceptable means, all water regardless of source. Contractor shall be responsible for disposal of
the water.
6.
Control groundwater in a manner that preserves strength of foundation soils, does not cause instability or
raveling of excavation slopes, and does not result in damage to existing structures. Where necessary, lower
water level in advance of excavation utilizing wells, wellpoints, jet educators, or similar positive methods.
The water level as measured by piezometers shall be maintained a minimum of 3 feet below prevailing
excavation level.
7.
Commence dewatering prior to any appearance of water in excavation and continue until Work is complete
to the extent that no damage results from hydrostatic pressure, flotation, or other causes.
8.
Open pumping with sumps and ditches will be allowed provided it does not result in boils, loss of fines,
softening of the ground, or instability of slopes.
9.
Install wells or wellpoints, if required, with suitable screens and filters so that continuous pumping of fines
does not occur. Arrange discharge to facilitate collection of samples by the Owner. During normal
pumping and upon development of wells, levels of fine sand or silt in the discharge water shall not exceed
5 ppm. Install sand tester on discharge of each pump during testing to verify that levels are not exceeded.
10.
Control grading around excavations to prevent surface water from flowing into excavation areas.
11.
No additional payment will be made for any supplemental measures to control seepage, groundwater, or
artesian head.
B.
Design:
1.
Designate and obtain the services of a qualified dewatering specialist to provide dewatering plan as may be
necessary to complete the Work.

Contractor shall be responsible for the accuracy of the drawings, design data, and operational records
required.
3.
Contractor shall be responsible for the design, installation, operation, maintenance, and any failure of any
component of the system.
C.
Damages:
1.
Contractor shall be responsible for and shall repair any damage to work in place, other contractor’s
equipment, utilities, residences, highways, roads, railroads, private and municipal well systems, adjacent
structures, natural resources, habitat, existing wells, and the excavation. Contractor responsibility shall also
include, damage to the bottom due to heave and including but not limited to, removal and pumping out of
the excavated area that may result from Contractor’s negligence, inadequate or improper design and
operation of the dewatering system, and any mechanical or electrical failure of the dewatering system.

SWPPP Updates and Amendments
The General Contractor must update the SWPPP and Site Maps daily to reflect the progress of construction
activities and general changes to the project site. SWPPP contact and contractor information and the record
of site stabilization activities log must be maintained by the General Contractor throughout the project.
BMPs that do not impact the hydraulic design of the site may be modified or added by the General
Contractor, and site maps updated accordingly, as needs arise. Examples of BMPs that do not typically
impact the hydraulic design of the site include silt fence, silt dike, wattles, construction exit and various
forms of temporary and permanent erosion controls (blankets, nets, seed, sod, etc.). Examples of BMPs
that commonly impact hydraulic design include storm water basins, diversions, check dams, inlet
protection or any product, process or system that changes the storm water flow path or storm water storage
capacity of the site or is located in an area of concentrated flow.
The General Contractor must submit a request for information (RFI) to the CEC and obtain written CEC
approval before modifying or adding sediment controls that may impact the hydraulic design of the site.
Substitution of any erosion or sediment control BMPs beyond those specified in the SWPPP must first be
approved in writing by the CEC. Substitutions are typically only approved if specified materials are not
available or there is a valid reason the specified BMP will not work.
Amending the SWPPP does not mean that it has to be reprinted. It is acceptable to add addenda, sketches,
new sections, details, and/or revised drawings that are initialed and dated.
H.
Discharge of Petroleum Products or Hazardous Substances
Discharge of petroleum products or other hazardous substances into storm water or the storm water (storm
sewer) system is subject to reporting and clean up requirements. See Section V.B.9. of this SWPPP for
state and local information on reporting spills. Refer to the General Permit for additional information. A
copy of the spill form is located in Appendix H and the General Permit is located in Appendix N.

INTRODUCTION
This SWPPP has been prepared for major activities associated with the construction of:
Distribution Center #6064-500, Cleburne, TX - Pavement Rehabilitation
This SWPPP must be implemented at the start of construction.
Construction phase pollutant sources anticipated at the site are disturbed (bare) soil, vehicle fuels and lubricants,
chemicals and coatings associated with site or building construction and pavement installation, constructiongenerated litter and debris, and building materials. Without adequate control there is a potential for each type of
pollutant to be transported by storm water.
Project construction will consist primarily of concrete pavement removal and replacement at the existing Walmart
Returns Distribution Center. The existing Distribution Center consists of a 381,898 square foot building, a 97,000
square foot building, and a 476,400 square foot building.. The Distribution Center is located on an approximately
103 acre site. The total disturbed area for this project site is 0.80 acres. There is no off-site area being disturbed as a
part of this project.
A.
Purpose
A major goal of pollution prevention efforts during project construction is to control soil and pollutants that
originate on the site and prevent them from flowing to surface waters. The purpose of this SWPPP is to
provide guidelines for achieving that goal. A successful pollution prevention program also relies upon
careful inspection and adjustments during the construction process in order to enhance its effectiveness.
B.
Scope
This SWPPP must be implemented before construction begins on the site. It primarily addresses the impact
of storm rainfall and runoff on areas of the ground surface disturbed during the construction process. In
addition, there are recommendations for controlling other sources of pollution that could accompany the
major construction activities. Applicability of this SWPPP will terminate when disturbed areas are
stabilized, permanent erosion and sedimentation controls are installed, temporary erosion and
sedimentation controls are removed, construction activities covered herein have ceased, and the project is
completed.
Forms which are necessary for implementing the SWPPP are included herein.
02370-8
Date: 06/15/2011
The General Permit for Storm Water Discharges Associated with Construction Activities prohibits most
non-storm water discharges during the construction phase. Allowable non-storm water discharges that
occur during construction on this project, which are generally covered by the General Permit, include:
1. Discharges from fire-fighting activities;
2. Fire hydrant flushings1;
3. Waters used to wash vehicles where detergents are not used;
4. Water used to control dust in accordance with Subpart 3.4.G;
5. Potable water including uncontaminated water line flushings;
6. Routine external building wash down that does not use detergents;
7. Pavement wash waters where spills or leaks of toxic or hazardous materials have not occurred
(unless all spilled material has been removed) and where detergents are not used;
8. Uncontaminated air conditioning or compressor condensate;
9. Uncontaminated ground water or spring water;
10. Foundation or footing drains where flows are not contaminated with process materials such as
solvents;
11. Uncontaminated excavation dewatering;
12. Landscape irrigation (with certain limitations).
Contractor shall consult State specific General Permit to determine specific allowable discharges that
are applicable to this specific project.
Best Management Practices (BMPs) must be implemented for the above allowable foreseeable discharges
for the duration of the project. Each non-storm water discharge should be noted in the SWPPP and have
proper erosion and sedimentation controls in place with the possible exception of discharges from fire
fighting activities.
The techniques described in this SWPPP focus on providing control of pollutant discharges with practical
approaches that utilize readily available expertise, material, and equipment.
The Owner referred to in this SWPPP is Wal-Mart Stores East, LP. The General Contractor shall construct
the site development improvements while working under contract with the Owner.
III.
PROJECT DESCRIPTION
Described below are the major construction activities that are the subject of this SWPPP. Also included in the
sequence are BMP installation activities that must take place prior to construction activities. NOTE: Down slope
protective measures must always be in place before soil is disturbed. Activities are presented in the order
(sequence) they are expected to be completed.
All activities and timeframes (beginning and ending dates) shall be noted on the Site Map and the “Record of
Stabilization and Construction Activity Dates” form found in Appendix J of this SWPPP. The sequence of
construction is as follows:
NOTE: Upon implementation and installation of the following areas: trailer, parking, lay down, porta-potty, wheel
wash, concrete washout, mason's area, fuel and material storage containers, solid waste containers, etc., immediately
denote them on the Site Maps and note any changes in location as they occur throughout the construction process.
In addition, note any off-site areas where fill is imported from or soil is exported to on the Site Maps.
Erosion Control Sequencing
1. Install SWPPP Information Sign.
2. Install silt dike on pavement as construction progress allows. Silt dike must be in place prior to subgrade
disturbing activities.
3. Replace pavement areas as shown on the plans. (Note: Pavement that has been removed should be replaced
immediately following its demolition.
4. Complete paving and stabilize any vegetated areas disturbed due to the construction activities (if
applicable).
5. Remove SWPPP Information Sign.
02370-9
Date: 06/15/2011
Note: The general contractor may complete construction-related activities concurrently only if preceding BMP's
have been completely installed. BMP-related steps in the above sequence are italicized for clarity.
The actual schedule for implementing pollutant control measures will be determined by project construction
progress and recorded by the General Contractor on the Soil Erosion/Sedimentation Control Operation Time
Schedule on the Erosion and Sedimentation Control plans (Site Maps). Down slope protective measures must
always be in place before soil is disturbed.

STORM WATER POLLUTION PREVENTION MEASURES AND CONTROLS
A variety of storm water pollutant controls are recommended for this project. Some controls are intended to
function temporarily and will be used as needed for pollutant control during the construction period. These include
temporary sediment barriers and permanent storm retention ponds (which can also function as temporary sediment
basins). Permanent stabilization will be accomplished in all disturbed areas by covering the soil with pavement,
building foundation, vegetation, or other forms of soil stabilization.
A.
Erosion and Sediment Controls
1.
Minimization of Disturbed Areas
Note to General Contractor: Owner has authority to limit surface area of erodible earth material
exposed by clearing and grubbing, excavation, borrow and embankment operations and to direct
General Contractor to provide immediate permanent or temporary pollution control measures
2.
Soil Stabilization
The purpose of soil stabilization is to prevent soil from eroding and leaving the site. In the natural
condition, soil is stabilized by native vegetation. The primary technique to be used at this project
for stabilizing site soils will be to provide a protective cover of grass, pavement, or building
structure.
a.)
Temporary Seeding or Stabilization – All denuded areas that will be inactive for 7 days
or more, must be stabilized temporarily with the use of fast-germinating annual
grass/grain varieties appropriate for site soil and climate conditions, straw/hay mulch,
wood cellulose fibers, tackifiers, netting and/or blankets. Stockpiles and diversion
ditches/berms must be stabilized to prevent erosion and dust issues.
Note to General Contractor: Temporary stabilization is not achieved simply through
seeding. In order for an area or stockpile to be sufficiently stabilized via temporary
vegetation, seed must germinate, grow and provide adequate vegetative density.
b.)
Permanent Seeding, Sodding or Mulching – All areas at final grade must be seeded or
sodded within 7 days after completion of work in that area. Seed immediately after final
grade is achieved and soils are prepared to take advantage of soil moisture and seed
germination. At the completion of ground-disturbing activities the entire site must have
permanent vegetative cover, meeting vegetative density requirements, or mulch per
landscape plan, in all areas not covered by hardscape (pavement, buildings, etc.). All
disturbed areas within a public road right-of-way are to receive sod unless noted
otherwise on the construction plans.
Except for small (<100 sq.ft.) level spots, seeded areas should be protected with mulch,
tackifier or a rolled erosion control product. Mulch must be crimped by disc or other
machinery.
02370-11
Date: 06/15/2011
All areas to be seeded must meet topsoil depth, pH and organic content requirements as
specified in the Section 02900 Specification – Planting.
Consideration is given to climate conditions, soil type and native vegetation when
designing the final landscaping plan. Note: Crushed/decomposed granite or other nonvegetative cover may be an acceptable final cover in arid climates.
To minimize the potential for erosion and maximize seed germination & growth, the
General Contractor must evaluate the short and long-term local forecast prior to applying
permanent seed or sod.
Final site stabilization is achieved when perennial vegetative cover provides permanent
stabilization with a density greater than 70 percent over the entire area to be stabilized by
vegetative cover. This area is exclusive of areas that are covered with rock (crushed granite,
gravel, etc.) or landscape mulch, paved or have a building or other permanent structure on them.
3.
Structural Controls
Storm water runoff for this project will be handled by the use of structural controls such as silt
dikes on pavement. Locations for and details of structural controls can be found on the sheet titled
Erosion Control Site Map of the Site Development Plans for Distribution Center. In case there are
questions regarding storm water runoff, the contractor shall refer to the General TPDES Permit for
requirements.
a)
Sedimentation Basins – Temporary sedimentation basins are depressions constructed
downslope of construction activity and located such that storm water runoff from upland
areas of less than 100 acres are diverted through the basin. Sediment basins shall be
constructed as directed by the SWPPP and shall be constructed as part of the initial Phase
I BMPs whenever practical. An overflow pipe is incorporated at the outlet to discharge
flow from the basin. Temporary and/or permanent discharge devices for use in
sedimentation basins shall be constructed with fill placement to endure these devices are
properly placed and the surrounding backfill is adequately tied to the basin levee. All
materials in the levee, including bedding materials for the discharge devices, shall be low
permeability, cohesive soil. Soil exhibiting high shrink/swell potential or containing
greater than 5% organics shall not be used. A marker signifying the need for cleanout of
each basin must be provided at the elevation shown on the Erosion Control Details
provided in the Site Development Plans for this project.
This control is not specified at this time
b)
Sedimentation Traps – Temporary sedimentation traps are depressions constructed
down slope of construction activity and located such that storm water runoff from upland
areas of less than 5 acres are diverted through the trap. Sedimentation traps shall be
constructed as indicated by the SWPPP and shall be constructed as part of the initial
BMPs whenever practical. An overflow weir is incorporated at the outlet to discharge
flow from the trap. Sedimentation traps shall be phased with the earthwork activity
where practical.
Sedimentation traps are designed for holding. One sedimentation trap is utilized on this
site adjacent to the stone construction exit. This sediment trap is designed to hold
sediment generated at the construction exit.
c)
Silt Fence – Silt fence is a synthetic permeable woven or non-woven geotextile fabric
incorporating metal support stakes at intervals sufficient to support the fence (5-feet
maximum distance between posts), water, and sediment retained by the fence. The fence
is designed to retain sediment-laden storm water and allow settlement of suspended soils
before the storm water flows through the fabric and discharges off-site. Silt fence shall
be located on the contour to capture overland, low-velocity sheet flows and is installed
with a wire fence backing for additional support.
02370-12
Date: 06/15/2011
Silt fences shown on this site are to be used to prevent silt from leaving the construction
site. If contractor uses silt fence in areas other than what are indicated on Construction
Drawings, drainage area is limited to ½ acre per 100 ft. of fence of wire-reinforced silt
fence for slopes less than 2 percent. Install silt fence at a fairly level grade along the
contour with the ends curved uphill to provide sufficient upstream storage volume for the
anticipated runoff. Silt fence shall be placed 5 feet beyond the toe of the slope.
d)
e)
Construction Exit – All site access must be confined to the construction exit(s) specified
by the Construction Mananger. It may be necessary to install a wheel wash system. If
this is done, a sediment trap control must be installed to treat the wash water before it
discharges from the site.
Storm Sewer Inlet Protection – Curb and grated inlets are protected from the intrusion
of sediment through a variety of measures as shown on the details included in the
Construction drawings. The primary mechanism is to place controls in the path of flow
sufficient to slow the sediment-laden water to allow settlement of suspended soils before
discharging into the storm sewer. It is possible that as construction progresses from
storm sewer installation through to paving that the inlet protection devices will change.
Note to General Contractor: All inlet protection devices create ponding of storm water
that can result in flooding or by-pass conditions.
f)
Check Dams – Defined channels subject to concentrated flows in larger quantities and
higher velocities may be protected with rock or other manufactured device (Geo-ridge for
example) that can be used as a check dam. The dams impound sediment-laden water and
allow for settlement of suspended soil before the storm water flows over and through the
device. At a minimum, dams shall be placed along the water course at linear intervals in
which the elevation of the bottom of the upper most check dam is at the same elevation as
the top of the check dam immediately below it. This will allow the most ponding
capacity and will not increase the velocity of the water flowing along the channel.
Location and spacing of check dams are shown on the Site Maps. Check dams are
composed of crushed stone or rip rap or of other manufactured devices. See the detail
sheet within the Construction Drawings for the types of dams to be used on this site.
g)
Diversion Ditch/Berm – Diversion ditches (swales) and berms (dikes) are constructed as
shown on the Site Maps at locations within the construction site to intercept overland
flow and direct or divert flow to a sediment basin or other point where discharge can be
controlled. Ditches are excavated in the surface soils with the spoils from the excavation
typically placed along the downstream edge of the ditch to provide additional capacity.
Berms are built up on the surface soils and compacted to create a stable diversion.
h)
Silt Dike on Pavement - Silt dikes on pavement are placed at locations indicated on the
Site Maps to capture any sediment being carried by overland flow across pavement
downstream of an area being disturbed. These devices are to be installed directly on the
pavement and shall have continuous and firm contact with pavement surface. Adhesive
shall be used to secure the device to the pavement as indicated on the detail in the
Construction Drawings. Devices must be in place prior to disturbance of upstream areas.
02370-13
Date: 06/15/2011
B.
Other Pollutant Controls
This section includes the controls of pollutants other than sediment and additional requirements of the
General Permit.
1.
Dust Control
Construction traffic must enter and exit the site at the stabilized construction exit. The purpose is
to trap dust and mud that would otherwise be carried off-site by construction traffic. Large areas
of soil that are denuded of vegetation and have no protection from particles being picked up and
carried by wind should be protected with a temporary cover or kept under control with water or
other soil adhering products to limit wind transported particles exiting the site perimeter.
Water trucks or other dust control agents will be used as needed during construction to minimize
dust generated on the site. Tackifiers may be used to hold soil in place and prevent dust.
Manufacturer recommendations for application locations and rates must be used for dust control
applications. Dust control must be provided by the General Contractor to a degree that is in
compliance with applicable local and state dust control regulations.
2.
Dewatering
Verify discharges from dewatering activities are allowed non-storm water discharges under the
General Permit. Obtain a dewatering permit according to state and local regulations, if discharges
from dewatering activities are not allowed under the General Permit. Discharges from dewatering
operations must be directed through an appropriate pollution prevention/treatment measure, such
as a pump discharge filter bag, sediment trap or sediment basin prior to being discharged from the
site or into a water body of the State. Under no circumstances are discharges from dewatering
operations to be discharged directly into streams, rivers, lakes or other areas off-site. Likewise,
discharges into storm sewer systems that do not drain to a suitable on-site treatment facility, such
as a basin, are also prohibited. Discharges from dewatering operations must also be conducted in
a manner sufficient to prevent erosion from the discharge runoff.
Use best management practices when dewatering. Place intake hose on a flotation or similar
device and do not pump directly from the bottom of the basin, trench, etc. Always pump through
a sediment control BMP and dewater within the permitted limits of disturbance to ensure
discharge criteria are achieved. Do not discharge on a slope greater than three percent or within
20’ of a surface water body. Dewatering should not occur during or immediately after
precipitation events, but exceptions will be evaluated on case by case basis.
3.
Solid Waste Disposal
No solid materials, including building materials, are allowed to be discharged from the site with
storm water. All solid waste, including disposable materials incidental to the major construction
activities, must be collected and placed in containers. The containers will be emptied as necessary
by a contract trash disposal service and hauled away from the site. Covers for the containers will
be provided as necessary to meet state and local requirements. Construct covers as practicable, or
required, to prevent storm water contact and pollutant discharges from solid waste receptacles.
The location of solid waste receptacles shall be shown on the Site Maps.
Substances that have the potential for polluting surface and/or groundwater must be controlled by
whatever means necessary in order to ensure that they do not discharge from the site. As an
example, special care must be exercised during equipment fueling and servicing operations. If a
spill occurs, it must be contained and disposed of so that it will not flow from the site or enter
groundwater, even if this requires removal, treatment, and disposal of soil. In this regard,
potentially polluting substances should be handled in a manner consistent with the impact they
represent.
4.
Sanitary Facilities
All personnel involved with construction activities must comply with state and local sanitary or
septic system regulations. Temporary sanitary facilities will be provided at the site throughout the
construction phase. They must be utilized by all construction personnel and will be serviced by a
commercial operator. The location of sanitary facilities shall be shown on the Site Maps. Portable
toilets must be securely anchored and are not allowed within 30’ of inlets or permitted limit of
disturbance or within 50’ of a water of the State. Any secondary containment for portable toilets
required by State or local regulations shall be provided by the Contractor.
02370-14
Date: 06/15/2011
5.
Non-Storm Water Discharges
Non-storm water components of site discharges must be clean water. Water used for construction
which discharges from the site must originate from a public water supply or private well approved
by the State Health Department. Water used for construction that does not originate from an
approved public supply must not discharge from the site. It can be retained in the ponds until it
infiltrates and evaporates. Other non-storm water discharges would include ground water. Only
uncontaminated ground water can be discharged from the site, as allowed by and in accordance
with applicable local ground water dewatering permits/regulations. When non-storm water is
discharged from the site, it must be done in a manner such that it does not cause erosion of the soil
during discharge.
Process water such as power washing and concrete cutting must be collected for treatment and
disposal. It is not to be flushed into the site storm drain system. If any dewatering permit is
required then it will be the responsibility of the Contractor to obtain.
6.
Concrete Waste from Concrete Ready-Mix Trucks
Discharge of excess or waste concrete and/or wash water from concrete trucks will be allowed on
the construction site, but only in specifically designated lined and diked areas prepared to prevent
contact between the concrete and/or wash water and storm water that will be discharged from the
site. Alternatively, waste concrete can be placed into forms to make rip rap or other useful
concrete products. The cured residue from the concrete washout diked areas shall be disposed in
accordance with applicable state and federal regulations. This jobsite superintendent is
responsible for assuring that these procedures are followed. The location of concrete washout
areas shall be shown on the Site Maps. Follow all applicable environmental regulations for
concrete wash out pits.
7.
Masons’ Area
Contractor shall identify masons’ area on the site and indicate location on the Site Map. To the
extent practical, all masonry tools, material, including sand and sacked cement or mortar
materials, and equipment shall be located within the area identified. Runoff control, such as berms
or diversion ditches, silt fence, straw wattles, or other means of containment shall be provided to
prevent the migration of storm water pollutants in runoff from the masons’ area. Receptacles for
debris and trash disposal shall also be provided.
8.
Fuel Tanks
Temporary on-site fuel tanks for construction vehicles shall meet all state and federal regulations.
Tanks shall have approved spill containment with the capacity required by the applicable
regulations. From NFPA 30: All tanks shall be provided with secondary containment (i.e.
containment external to and separate from primary containment). Secondary containment shall be
constructed of materials of sufficient thickness, density, and composition so as not to be
structurally weakened as a result of contact with the fuel stored and capable of containing
discharged fuel for a period of time equal to or longer than the maximum anticipated time
sufficient to allow recovery of discharged fuel. It shall be capable of containing 110% of the
volume of the primary tank if a single tank is used, or in the case of multiple tanks, 150% of the
largest tank or 10% of the aggregate, whichever is larger.
The tanks shall be in sound condition free of rust or other damage which might compromise
containment. Fuel storage areas will meet all EPA, OSHA and other regulatory requirements for
signage, fire extinguisher, etc. Hoses, valves, fittings, caps, filler nozzles, and associated
hardware shall be maintained in proper working condition at all times. The location of fuel tanks
shall be shown on the Site Maps and shall be located to minimize exposure to weather and surface
water drainage features.
A Spill Prevention, Control and Countermeasure (SPCC) Plan must be developed if aboveground
oil storage capacity at the construction site exceeds amount specified by state. Containers with a
storage capacity of 55-gallons or less are not included when calculating site storage capacity. The
General Contractor shall work with the CEC to develop and implement a SPCC Plan in
accordance with the Oil Pollution Prevention regulation at Title 40 of the Code of Federal
Regulations, Part 112, (40 CFR 112).
02370-15
Date: 06/15/2011
9.
Hazardous Material Management and Spill Reporting Plan
Any hazardous or potentially hazardous material that is brought onto the construction site will be
handled properly in order to reduce the potential for storm water pollution. All materials used on
this construction site will be properly stored, handled, dispensed and disposed of following all
applicable label directions. Flammable and combustible liquids will be stored and handled
according to 29 CFR 1926.152. Only approved containers and portable tanks shall be used for
storage and handling of flammable and combustible liquids.
Material Safety Data Sheets (MSDS) information will be kept on site for any and all applicable
materials.
In the event of an accidental spill, immediate action will be undertaken by the General Contractor
to contain and remove the spilled material. All hazardous materials will be disposed of by the
Contractor in the manner specified by federal, state and local regulations and by the manufacturer
of such products. As soon as possible, the spill will be reported to the appropriate agencies. As
required under the provisions of the Clean Water Act, any spill or discharge entering waters of the
United States will be properly reported. The General Contractor will prepare a written record of
any spill and associated clean-up activities of petroleum products or hazardous materials in excess
of 1 gallon or reportable quantities, which ever is less. The General Contractor will provide notice
to Construction Manager immediately upon identification of a reportable spill. A spill report form
is located in Appendix H.
Any spills of petroleum products or hazardous materials in excess of Reportable Quantities as
defined by EPA or the state or local agency regulations, shall be immediately reported to the EPA
National Response Center (1-800-424-8802) and appropriate State agency as listed in the General
Permit.
In order to minimize the potential for a spill of petroleum product or hazardous materials to come
in contact with storm water, the following steps will be implemented:
a)
All materials with hazardous properties (such as pesticides, petroleum products,
fertilizers, detergents, construction chemicals, acids, paints, paint solvents, additives for
soil stabilization, concrete, curing compounds and additives, etc.) will be stored in a
secure location, under cover, when not in use.
b)
The minimum practical quantity of all such materials will be kept on the job site and
scheduled for delivery as close to time of use as practical.
c)
A spill control and containment kit (containing for example, absorbent material such as
kitty litter or sawdust, acid neutralizing agent, brooms, dust pans, mops, rags, gloves,
goggles, plastic and metal trash containers, etc.) will be provided on the construction site
and location(s) shown on Site Maps.
d)
All of the product in a container will be used before the container is disposed of. All
such containers will be triple rinsed, with water prior to disposal. The rinse water used in
these containers will be disposed of in a manner in compliance with state and federal
regulations and will not be allowed to mix with storm water discharges.
e)
All products will be stored in and used from the original container with the original
product label.
f)
All products will be used in strict compliance with instructions on the product label.
g)
The disposal of excess or used products will be in strict compliance with instructions on
the products label.

Long-Term Pollutant Controls
Storm water pollutant control measures installed during construction, that will also provide storm
water management benefits after construction, include vegetation if vegetated areas are disturbed
by the construction activities.
“Best Management Practices” (BMPs)
Owner has authority to limit surface area of erodible earth material exposed by clearing and grubbing,
excavation, borrow and embankment operations and to direct the General Contractor to provide immediate
permanent or temporary pollution control measures.
During the construction phase, the General Contractor shall implement the following measures:
D.
1)
Materials resulting from the clearing and grubbing or excavation operations shall be stockpiled up
slope from adequate sedimentation controls. Ensure that materials removed to an off-site location
shall be protected with appropriate controls and properly permitted and otherwise comply with
applicable laws, all in accordance with this SWPPP, including Section V.D. below.
2)
The General Contractor shall designate areas on the Site Maps for equipment cleaning,
maintenance, and repair. The General Contractor and subcontractors shall utilize such designated
areas. Cleaning, maintenance, and repair areas shall be protected by a temporary perimeter berm,
shall not occur within 150 feet of any waterway, water body or wetland, and in areas located as far
as practical from storm sewer inlets.
3)
Use of detergents for large scale washing is prohibited (i.e. vehicles, buildings, pavement surfaces,
etc.).
4)
Chemicals. Paints, solvents, fertilizers, and other toxic materials must be stored in waterproof
containers. Except during application, the containers, the contents must be kept in trucks or within
storage facilities. Runoff containing such material must be collected, removed from the site,
treated, and disposed of at an approved solid waste and chemical disposal facility.
5)
Clearing and grubbing shall be held to a minimum necessary for grading and equipment
operations. Construction must follow the sequencing specified on the plans and in the SWPPP to
minimize the exposure time of graded or denuded areas.
Material Storage, Borrow, or Disposal Areas Outside of Permitted Limits of Disturbance
This section describes roles and responsibilities of Walmart General Contractors in verifying and
documenting that activities associated with site construction at material storage, borrow, or disposal areas
outside of the Permitted Limits of Disturbance have obtained proper coverage under the TPDES program.
Definitions Applicable to this Section
Site - The location(s) described in this SWPPP and on the associated Site Maps at which Walmart or a
Walmart contractor has operational control.
Operational Control - Control over construction plans and specifications, including the ability to make
modifications to those plans and specifications, or day-to-day operational control of those activities at the
Site which are necessary to ensure compliance with the SWPPP.
Off-site – Any area outside the Limits of Disturbance as shown on the Site Maps in the SWPPP. This is
not necessarily the same as the property ownership boundary.
Permitted Limits of Disturbance - Any area of the Site for which the operator(s) are authorized to disturb
the ground surface or conduct construction-related activities (i.e. areas shown inside the Limits of
Disturbance on the Site Maps in the SWPPP).
Material – Rock, soil, or other construction materials obtained as part of an earth disturbing activity.
02370-17
Date: 06/15/2011
Responsibilities of the General Contractor
When any material storage, borrow, or disposal will take place during construction outside of Permitted
Limits of Disturbance the General Contractor must:
1.
2.
3.
4.
5.
VI.
Verify that any proposed material storage, borrow, or disposal areas have obtained proper
coverage under the TPDES program. This shall include obtaining copies of signed and submitted
TPDES Notices of Intent or applications, Storm Water Discharge Authorizations, or other
documentation necessary to verify compliance with the TPDES program (e.g., documentation
from local qualified programs, MS4s, Soil Conservation District permits, etc.)
Prior to any Storage, Borrow, or Disposal activities properly execute the Material Storage,
Borrow, or Disposal Manifest and related Contract for each area. Blank copies of the appropriate
forms are provided in Appendix M.
Copies of the Material Storage, Borrow, or Disposal Manifest and related Contract for Removal
and Acceptance of Soil shall be provided to the Construction Manager upon execution. The Soil
Removal and Acceptance Manifest shall not be amended or changed without prior approval from
the Construction Manager.
The General Contractor shall complete and keep current the Off-Site Material box on the project
site map and update the map and site stabilization log to indicate locations where, and dates when,
storage, borrow, or disposal occur on the Walmart Site.
All documentation obtained as described in this section shall be retained in the SWPPP binder at
the site and in accordance with the Retention of Records as described in Part I.D of Section 02370.
LOCAL PLANS
In addition to this SWPPP, construction activities associated with this project must comply with any guidelines set forth by
local regulatory agencies. The General Contractor shall maintain documents evidencing such compliance on the jobsite.
VII.
INSPECTIONS AND SYSTEM MAINTENANCE
Between the time this SWPPP is implemented and the completion of the project, all disturbed areas and pollutant controls
must be inspected daily. The purpose of site inspections is to assess performance of pollutant controls. The inspections will
be conducted by the General Contractor’s Site Superintendent. Based on these inspections, the General Contractor will
decide whether it is necessary to modify this SWPPP, add or relocate controls, or revise or implement additional Best
management Practices in order to prevent pollutants from leaving the site via storm water runoff. The General Contractor has
the duty to cause pollutant control measures to be repaired, modified, supplemented, or take additional steps as necessary in
order to achieve effective pollutant control. Note: If a BMP is covered by snow, mark the BMP as not applicable and
document the reason the BMP can not be inspected on the daily report.
Examples of specific items to evaluate during site inspections are listed below. This list is not intended to be comprehensive.
During each inspection, the inspector must evaluate overall pollutant control system performance as well as particular details
of individual system components. Additional factors should be considered as appropriate to the circumstances.
A.
Construction Exit and Track Out
Locations where vehicles enter and exit the site must be inspected for evidence of off-site sediment
tracking. A stabilized construction exit shall be established where vehicles enter and exit the site. Due to
the nature of this project, a stone construction exit is not required. Contractor shall implement procedure
and facilities, as needed, to prevent tracking sediment onto roadways or parking lot. Any sediment
deposited on the roadway shall be swept as necessary throughout the day or at the end of every day and
disposed of in an appropriate manner. Sediment shall NOT be washed into storm sewer systems.
Note to General Contractor: Track out is a sediment release (sediment from the construction site was
allowed beyond the permitted limits of disturbance). All sediment releases must be reported to the
Construction Manager. See Item H below for additional information.
B.
Erosion Control Devices
Rolled erosion control products (nets, blankets, turf reinforcement mats) and marginally vegetated areas
(areas not meeting required vegetative densities for final stabilization) must be inspected daily. Rilling,
rutting and other signs of erosion indicate the erosion control device is not functioning properly and
additional erosion control devices are warranted.
02370-18
Date: 06/15/2011
C.
Sediment Control Devices
Sediment barriers, traps and basins must be inspected and they must be cleaned out at such time as their
original capacity has been reduced by 50 percent. All material excavated from behind sediment barriers or
in traps and basins shall be incorporated into on-site soils or spread out on an upland portion of the site and
stabilized. To minimize the potential for sediment releases from the project site perimeter control devices
shall be inspected with consideration given to changing up-gradient conditions.
D.
Material Storage Areas
Material storage areas should be located to minimize exposure to weather. Inspections shall evaluate
disturbed areas and areas used for storing materials that are exposed to rainfall for evidence of, or the
potential for, pollutants entering the drainage system or discharging from the site. If necessary, the
materials must be covered or original covers must be repaired or supplemented. Also, protective berms
must be constructed, if needed, in order to contain runoff from material storage areas. All state and local
regulations pertaining to material storage areas will be adhered to.
E.
Vegetation
Consideration must be given to anticipated climate and seasonal conditions when specifying and planting
seed. Seed shall be free of weedy species and appropriate for site soils and regional climate. Seed and
mulch per the construction drawings and the 02900 Planting specification immediately after topsoil is
applied and final grade is reached. Grassed areas shall be inspected to confirm that a healthy stand of grass
is maintained. The site has achieved final stabilization once all areas are covered with building foundation
or pavement, or have a stand of grass with a minimum of 70 percent density or greater of natural
background cover over the entire vegetated area. Vegetated areas must be watered, fertilized, and reseeded
as needed to achieve this requirement. The vegetative density must be maintained through project
completion to be considered stabilized. Areas protected by erosion control blankets are not permanently
stabilized until the requirement for final vegetative density is achieved.
Rip-rap, mulch, gravel, decomposed granite or other equivalent permanent stabilization measures may be
employed in lieu of vegetation based on site-specific conditions and governing authority approval.
F.
Discharge Points
All discharge points must be inspected to determine whether erosion and sediment control measures are
effective in preventing discharge of sediment from the site or impacts to receiving waters.
G.
Off-Site or Special Project Areas
There are no special projects, beyond the Walmart permitted limits of disturbance, requiring inspection and
maintenance associated with this construction project.
H.
Sediment Releases
The Construction Manager must be notified each and every time sediment is allowed beyond permitted
limits of disturbance. This includes sediment that escapes or is allowed to leave via designed discharge
points. Storm water that leaves the permitted limits of disturbance and is discolored contains soil particles
(sediment) and must be treated as a sediment release.
When calling the Construction Manager to report a sediment release the General Contract should leave the
following information:
1. Store Number & Sequence
2. Store City & State
3. Caller (full name & firm)
4. Caller Telephone Number
5. Sediment Release Date
6. Was a rain event associated with release (Yes or No)?
6b. If yes, what was duration of rain event & total amount of rain received?
6c. If no, what caused the sediment release?
7. Where on the jobsite did the release occur?
8. Did the sediment release occur beyond the permitted limits of disturbance (Yes or No)?
If yes,
8b. What BMPs failed to allow the sediment release to occur?
02370-19
Date: 06/15/2011
8c. Did sediment enter a water body or wetland?
8d. Did sediment enter a storm water inlet?
8e. Did sediment enter an adjacent street or property?
8f. Estimate, in cubic yards, how much sediment left the site:
8g. Has all off-site sediment been cleaned up (Yes or No)?
If no, when will sediment clean up be completed?
8h. Is there a requirement to notify the governing agency of this release (Yes or No)?
9. How have BMPs been modified / improved to prevent future sediment releases?
Ultimately, it is the responsibility of the General Contractor to assure the adequacy of site pollutant discharge
controls. Actual physical site conditions or contractor practices could make it necessary to install more structural
controls than are shown on the plans. For example, localized concentrations of runoff could make it necessary to
install additional sediment barriers. Assessing the need for additional controls and implementing them or adjusting
existing controls will be a continuing aspect of this SWPPP until the site achieves final stabilization. Any
modifications, additions or deletions of sediment control devices that may alter the hydraulic design of the site or are
located in areas of potential high flow (basins, traps, check dams, diversions. etc.) must be approved by the CEC
through the request for information process (RFI).

3(b). Indicate is the site is part of a common plan of development or for sale.
Construction activities that disturb less than one acre, unless they are part of a larger common plan that disturbs more than one acre, do not require permit
coverage.
Construction activities that disturb between one and five acre, unless they are part of a common plan that disturbs five acres or more acres, do not require
submission of an NOI. Therefore, the estimated area of land disturbed should not be less than five, unless the project is part of a larger common plan that
disturbs five or more acres.
ADisturb@ means any clearing, grading, excavating, or other similar activities. If you have any questions about this item, please call the storm water
technical staff at (512)239-4671.
4. Discharge Information
4 (a). The storm water may be discharged directly to a receiving stream or through a MS4* from your site. It eventually reaches a receiving water body
such as a local stream or lake, possibly via a drainage ditch. You must provide the name of the water body that receives the discharge from the site (a
local stream or lake).
4 (b). The classified segment number(s) is REQUIRED to get coverage. Go to the link to find the segment number of the classified water body where
storm water will flow http://www.tceq.state.tx.us/compliance/monitoring/water/quality/data/wqm/viewer/viewer.html . Call Water Quality Assessments
at 512/239-4671 for further assistance. Another source for segments is: http://www.tceq.state.tx.us/comm_exec/forms_pubs/pubs/gi/gi-316/index.html
4 (c). If any surface water body(s) receiving discharges from the construction site are on the latest EPA-approved CWA § 303(d) list of impaired waters,

See maps on the TCEQ website to determine if the site is located within the Recharge Zone, Contributing Zone, or Contributing Zone within the
Transition Zone of the Edwards Aquifer at http://www.tceq.state.tx.us/compliance/field_ops/eapp/viewer.html.
If the discharge or potential discharge is within the Recharge Zone, Contributing Zone, or Contributing Zone within the Transition Zone of the Edwards
Aquifer, a site specific authorization approved by the Executive Director under the Edwards Aquifer Protection Program (30 TAC Chapter 213) is
required before construction can begin.

Pollution Prevention Plan. The certification must be answered “Yes” for coverage under the general permit.
E. CERTIFICATIONS
Failure to indicate AYes@ to ALL of the certification items may result in denial of coverage under the general permit.
The certification must bear an original signature of a person meeting the signatory requirements specified under 30 Texas Administrative Code '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:
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

Section 1: Erosion & Sediment Control – Construction Activities
SWPPP Cut Sheet:
Filtrexx® Sediment Control
Sediment & Perimeter Control Technology
PURPOSE & DESCRIPTION
Filtrexx® Sediment control is a three-dimensional
tubular sediment control and storm water runoff
filtration device typically used for perimeter control
of sediment and other soluble pollutants (such as
phosphorus and petroleum hydrocarbons), on and
around construction activities.
3.
APPLICATION
4.
Filtrexx® Sediment control is to be installed down
slope of any disturbed area requiring erosion and
sediment control and filtration of soluble pollutants
from runoff. Sediment control is effective when
installed perpendicular to sheet or low concentrated
flow. Acceptable applications include:
• Site perimeters
• Above and below disturbed areas subject to sheet runoff, interrill and rill erosion
• Above and below exposed and erodable slopes
• Around area drains or inlets located in a ‘sump’
• On compacted soils where trenching of silt fence is difficult or impossible
• Around sensitive trees where trenching of silt
fence is not beneficial for tree survival or may unnecessarily disturb established vegetation.
• On frozen ground where trenching of silt fence is impossible.
• On paved surfaces where trenching of silt fence is impossible.
5.
6.
7.
8.
INSTALLATION
1. Sediment control used for perimeter control of sediment and soluble pollutants in storm runoff shall meet Filtrexx® Soxxtm Material Specifications and use Certified Filtrexx® FilterMediatm.
2. Contractor is required to be Filtrexx® Certifiedtm as determined by Filtrexx® International, LLC 9.
(440-926-2607 or visit website at www.filtrexx. com). Certification shall be considered current if appropriate identification is shown during time of bid or at time of application (current listing can be found at www.filtrexx.com). Look for the Filtrexx® Certifiedtm Seal.
Sediment control will be placed at locations
indicated on plans as directed by the Engineer.
Sediment control should be installed parallel to the base of the slope or other disturbed area. In extreme conditions (i.e., 2:1 slopes), a second Sediment control shall be constructed at the top of the slope.
Effective Soxx™ height in the field should be as follows: 8” Diameter Sediment control = 6.5” high, 12” Diameter Sediment control = 9.5” high,
18” Diameter SiltSoxx™ = 14.5” high, 24”
Diameter Sediment control = 19” high.
Stakes shall be installed through the middle of the Sediment control on 10 ft (3m) centers, using 2 in (50mm) by 2 in (50mm) by 3 ft (1m) hard wood stakes. In the event staking is not possible, i.e., when Sediment control is used on
pavement, heavy concrete blocks shall be used behind the Sediment control to help stabilize
during rainfall/runoff events.
Staking depth for sand and silt loam soils shall be 12 in (300mm), and 8 in (200mm) for clay soils.
Loose compost may be backfilled along the upslope side of the Sediment control, filling the seam between the soil surface and the device,
improving filtration and sediment retention.
If the Sediment control is to be left as a
permanent filter or part of the natural landscape, it may be seeded at time of installation for
establishment of permanent vegetation. The
Engineer will specify seed requirements.
Construction Activities | Section 1: Erosion & Sediment Control | 323
10. Filtrexx® Sediment control is not to be used in perennial, ephemeral, or intermittent streams.
See design drawing schematic for correct Filtrexx® Sediment control installation (Figure 1.1).
INSPECTION and MAINTENANCE
Routine inspection should be conducted within
24 hrs of a runoff event or as designated by the
regulating authority. Sediment control should be
regularly inspected to make sure they maintain their
shape and are producing adequate hydraulic flowthrough. If ponding becomes excessive, additional
Sediment control may be required to reduce effective
slope length or sediment removal may be necessary.
Sediment control shall be inspected until area above
has been permanently stabilized and construction
activity has ceased
1. The Contractor shall maintain the Sediment control in a functional condition at all times and it shall be routinely inspected.
2. If the Sediment control has been damaged, it shall be repaired, or replaced if beyond repair.
3. The Contractor shall remove sediment at the base of the upslope side of the Sediment control
when accumulation has reached 1/2 of the effective height of the Sediment control, or as directed by the Engineer. Alternatively, a new Sediment control can be placed on top of and slightly behind the original one creating more sediment storage capacity without soil disturbance.
4. Sediment control shall be maintained until disturbed area above the device has been permanently stabilized and construction activity has ceased.
5. The FilterMediatm will be dispersed on site once disturbed area has been permanently stabilized, construction activity has ceased, or as determined by the Engineer.
6. For long-term sediment and pollution control applications, Sediment control can be seeded at the time of installation to create a vegetative filtering system for prolonged and increased filtration of sediment and soluble pollutants (contained vegetative filter strip). The appropriate seed mix shall be determined by the Engineer.

Section B.
Definitions
Arid Areas - Areas with an average annual rainfall of 0 to 10 inches.
Best Management Practices (BMPs) - Schedules of activities, prohibitions of practices, maintenance
procedures, structural controls, local ordinances, and other management practices to prevent or reduce the
discharge of pollutants. BMPs also include treatment requirements, operating procedures, and practices to
control construction site runoff, spills or leaks, waste disposal, or drainage from raw material storage areas.
Commencement of Construction - The initial disturbance of soils associated with clearing, grading, or
excavation activities, as well as other construction-related activities (e.g., stockpiling of fill material,
demolition)
Common Plan of Development - A construction activity that is completed in separate stages, separate
phases, or in combination with other construction activities. A common plan of development (also known as
a “common plan of development or sale”) is identified by the documentation for the construction project that
identifies the scope of the project, and may include plats, blueprints, marketing plans, contracts, building
permits, a public notice or hearing, zoning requests, or other similar documentation and activities. A
common plan of development does not necessarily include all construction projects within the jurisdiction of
a public entity (e.g., a city or university). Construction of roads or buildings in different parts of the
jurisdiction would be considered separate “common plans,” with only the interconnected parts of a project
being considered part of a “common plan” (e.g., a building and its associated parking lot and driveways,
airport runway and associated taxiways, a building complex, etc.). Where discrete construction projects
occur within a larger common plan of development or sale but are located ¼ mile or more apart, and the area
between the projects is not being disturbed, each individual project can be treated as a separate plan of
development or sale, provided that any interconnecting road, pipeline or utility project that is part of the
same “common plan” is not included in the area to be disturbed.
Discharge – For the purposes of this permit, the drainage, release, or disposal of pollutants in storm water
and certain non-storm water from areas where soil disturbing activities (e.g., clearing, grading, excavation,
stockpiling of fill material, and demolition), construction materials or equipment storage or maintenance
(e.g., fill piles, borrow area, concrete truck washout, fueling), or other industrial storm water directly related
to the construction process (e.g., concrete or asphalt batch plants) are located.
Edwards Aquifer - As defined under Texas Administrative Code § 213.3 of this title (relating to the
Edwards Aquifer), that 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 lesspermeable Comanche Peak and Walnut Formations north of the Colorado River, and underlie the lesspermeable 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 Texas Commission on Environmental Quality and the
Page 4
appropriate regional office.
The Edwards Aquifer Map Viewer, located at
http://www.tceq.state.tx.us/compliance/field_ops/eapp/mapdisclaimer.html, can be used to determine where
the recharge zone is located.
Edwards Aquifer Contributing Zone - The area or watershed where runoff from precipitation flows
downgradient to the recharge zone of the Edwards Aquifer. The contributing zone is located upstream
(upgradient) and generally north and northwest of the recharge zone for the following counties: all areas
within Kinney County, except the area within the watershed draining to Segment 2304 of the Rio Grande
Basin; all areas within Uvalde, Medina, Bexar, and Comal Counties; all areas within Hays and Travis
Counties, except the area within the watersheds draining to the Colorado River above a point 1.3 miles
upstream from Tom Miller Dam, Lake Austin at the confluence of Barrow Brook Cove, Segment 1403 of
the Colorado River Basin; and all areas within Williamson County, except the area within the watersheds
draining to the Lampasas River above the dam at Stillhouse Hollow reservoir, Segment 1216 of the Brazos
River Basin. The contributing zone is illustrated on the Edwards Aquifer map viewer at
http://www.tceq.state.tx.us/compliance/field_ops/eapp/mapdisclaimer.html.
Facility or Activity – For the purpose of this permit, a construction site or construction support activity that
is regulated under this general permit, including all contiguous land and fixtures (e.g., ponds and materials
stockpiles), structures, or appurtances used at a construction site or industrial site described by this general
permit.
Final Stabilization - A construction site status where any of the following conditions are met:
(a)
All soil disturbing activities at the site have been completed and a uniform (i.e., evenly
distributed, without large bare areas) perennial vegetative cover with a density of at least
70% 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:
(c)
(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. If temporary
stabilization is not feasible, then the homebuilder may fulfill this requirement by
retaining perimeter controls or other best management practices, and informing the
homeowner of the need for removal of temporary controls and the establishment of
final stabilization.
For construction activities on land used for agricultural purposes (e.g. 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 surface water and areas
that are not being returned to their preconstruction agricultural use must meet the final
stabilization conditions of condition (a) above.
Page 5
(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:
(1)
Temporary erosion control measures (e.g., degradable rolled erosion control product)
are selected, designed, and installed along with an appropriate seed base to provide
erosion control for at least three years without active maintenance by the operator,
and
(2)
The temporary erosion control measures are selected, designed, and installed to
achieve 70 percent vegetative coverage within three years.

all waters which are currently used, were used in the past, or may be susceptible to use in
interstate or foreign commerce, including all waters which are subject to the ebb and flow of
the tide;
(b)
all interstate waters, including interstate wetlands;
(c)
all other waters such as intrastate lakes, rivers, streams (including intermittent streams),

linear sites may be relocated, as necessary, along the length of the project, and the
notice must be safely and readily available for viewing by the general public; local,
state, and federal authorities); and
(c)
provide a copy of the signed and certified construction site notice to the operator of
any municipal separate storm sewer system receiving the discharge at least two days
prior to commencement of construction activities.
Operators of small construction activities as defined in Part I of this general permit shall not
submit an NOI for coverage unless otherwise required by the executive director.
As described in Part I (Definitions) of this general permit, large construction activities
include those that will disturb less than five (5) acres of land, but that are part of a larger
common plan of development or sale that will ultimately disturb five (5) or more acres of
land, and must meet the requirements of Part II.E.3. below.
3.
Authorization for Large Construction Activities:
Operators of large construction activities that qualify for coverage under this general permit
must meet all of the following conditions:
(a)
develop a SWP3 according to the provisions of this general permit that covers either
the entire site or all portions of the site for which the applicant is the operator, and
implement that plan prior to commencing construction activities;
(b)
primary operators must submit a Notice of Intent (NOI), using a form provided by
the executive director, at least seven (7) days prior to commencing construction
activities, or if utilizing electronic submittal, prior to commencing construction
activities. If an additional primary operator is added after the initial NOI is
submitted, the new primary operator must submit an NOI at least seven (7) days
before assuming operational control, or if utilizing electronic NOI submittal, prior to
assuming operational control. If the primary operator changes after the initial NOI is
submitted, the new primary operator must submit a paper NOI or an electronic NOI
at least ten (10) days before assuming operational control;
(c)
all primary operators must also post a copy of the signed NOI at the construction site
in a location where it is readily available for viewing by the general public, local,
Page 16
state, and federal authorities prior to commencing construction activities, and must
maintain the NOI in that location until completion of the construction activity;
4.
(d)
all operators of large construction activities must post a site notice in accordance
with Part III.D.2. of this permit. The site notice must be located where it is safely
and readily available for viewing by the general public, local, state, and federal
authorities prior to commencing construction, and must be maintained in that
location until completion of the construction activity (for linear construction
activities, e.g. pipeline or highway, the site notice must be placed in a publicly
accessible location near where construction is actively underway; notice for these
linear sites may be relocated, as necessary, along the length of the project, and the
notice must be safely and readily available for viewing by the general public; local,

(e)
all primary operators must provide a copy of the signed NOI to the operator of any
municipal separate storm sewer system (MS4) receiving the discharge and to any
secondary operator, at least seven (7) days prior to commencing construction
activities, and must list in the SWP3 the names and addresses of all MS4 operators
receiving a copy.
(f)
All persons meeting the definition of “secondary operator” in Part I of this permit are
hereby notified that they are regulated under this general permit, but are not required
to submit an NOI, provided that another operator(s) at the site has submitted an NOI,
or is required to submit an NOI and the secondary operator has provided notification
to the operator(s) of the need to obtain coverage (with records of notification
available upon request). Any secondary operator notified under this provision may
alternatively submit an NOI under this general permit, may seek coverage under an
alternative TPDES individual permit, or may seek coverage under an alternative
TPDES general permit if available.
Waivers for Small Construction Activities:
Part II.G. describes how operators of certain small construction activities may obtain a
waiver from coverage.
5.
Effective Date of Coverage
(a)
Operators of small construction activities as described in either Part II.E.1. or II.E.2.
above are authorized immediately following compliance with the applicable
conditions of Part II.E.1. or II.E.2. Secondary operators of large construction
activities as described in Part II.E.3. above are authorized immediately following
compliance with the applicable conditions in Part II.E.3. For activities located in
areas regulated by 30 TAC Chapter 213, related to the Edwards Aquifer, this
authorization to discharge is separate from the requirements of the operator’s
responsibilities under that rule. Construction may not commence for sites regulated
under 30 TAC Chapter 213 until all applicable requirements of that rule are met.
(b)
Primary operators of large construction activities as described in Part II.E.3. above
are provisionally authorized seven (7) days from the date that a completed NOI is
Page 17
postmarked for delivery to the TCEQ, unless otherwise notified by the executive
director. If electronic submission of the NOI is provided, and unless otherwise
notified by the executive director, primary operators are authorized immediately
following confirmation of receipt of the NOI by the TCEQ. Authorization is nonprovisional when the executive director finds the NOI is administratively complete
and an authorization number is issued for the activity. For activities located in areas
regulated by 30 TAC Chapter 213, related to the Edwards Aquifer, this authorization
to discharge is separate from the requirements of the operator’s responsibilities under
that rule. Construction may not commence for sites regulated under 30 TAC Chapter
213 until all applicable requirements of that rule are met.
(c)
6.
Operators are not prohibited from submitting late NOIs or posting late notices to
obtain authorization under this general permit. The TCEQ reserves the right to take
appropriate enforcement actions for any unpermitted activities that may have
occurred between the time construction commenced and authorization was obtained.
Notice of Change (NOC)
If relevant information provided in the NOI changes, an NOC must be submitted at least 14
days before the change occurs, if possible. Where 14-day advance notice is not possible, the
operator must submit an NOC within 14 days of discovery of the change. If the operator
becomes aware that it failed to submit any relevant facts or submitted incorrect information
in an NOI, the correct information must be provided to the executive director in an NOC
within 14 days after discovery. The NOC shall be submitted on a form provided by the
executive director, or by letter if an NOC form is not available. A copy of the NOC must
also be provided to the operator of any MS4 receiving the discharge, and a list must be
included in the SWP3 that includes the names and addresses of all MS4 operators receiving a
copy.
Information that may be included on an NOC includes, but is not limited to, the following:
the description of the construction project, an increase in the number of acres disturbed (for
increases of one or more acres), or the operator name. A transfer of operational control from
one operator to another, including a transfer of the ownership of a company, may not be
included in an NOC. A transfer of ownership of a company includes changes to the
structure of a company, such as changing from a partnership to a corporation or changing
corporation types, so that the filing number (or charter number) that is on record with the
Texas Secretary of State must be changed.
An NOC is not required for notifying TCEQ of a decrease in the number of acres disturbed.
This information must be included in the storm water pollution prevention plan (SWP3) and
retained on site.
7.
Signatory Requirement for NOI Forms, Notice of Termination (NOT) Forms, NOC Letters,
and Construction Site Notices
NOI forms, NOT forms, NOC letters, and Construction Site Notices that require a signature

under this general permit will no longer occur, or that the applicant to terminate
coverage is no longer the operator of the facility or construction site, and that all
temporary structural erosion controls have either been removed, will be removed on
a schedule defined in the SWP3, or have been transferred to a new operator if the
new operator has applied for permit coverage. Erosion controls that are designed to
remain in place for an indefinite period, such as mulches and fiber mats, are not
required to be removed or scheduled for removal.
Termination of Coverage for Small Construction Sites and for Secondary Operators at Large
Construction Sites
Each operator that has obtained automatic authorization and has not been required to submit
an NOI must remove the site notice upon meeting any of the conditions listed below,
complete the applicable portion of the site notice related to removal of the site notice, and
submit a copy of the completed site notice to the operator of any MS4 receiving the
discharge (or provide alternative notification as allowed by the MS4 operator, with
documentation of such notification included in the SWP3), within 30 days of meeting any of
the following conditions:
(a)
final stabilization has been achieved on all portions of the site that are the
responsibility of the permittee;
(b)
a transfer of operational control has occurred (See Section II.F.4. below); or
Page 20
(c)
the operator has obtained alternative authorization under an individual or general
TPDES permit.
Authorization to discharge under this general permit terminates immediately upon removal
of the applicable site notice. Compliance with the conditions and requirements of this permit
is required until the site notice is removed.
4.
Transfer of Operational Control
Coverage under this general permit is not transferable. A transfer of operational control
includes changes to the structure of a company, such as changing from a partnership to a
corporation, or changing to a different corporation type such that a different filing (or
charter) number is established with the Texas Secretary of State.
When the primary operator of a large construction activity changes or operational control is
transferred, the original operator must submit a Notice of Termination (NOT) within ten (10)
days prior to the date that responsibility for operations terminates, and the new operator must
submit an NOI at least ten (10) days prior to the transfer of operational control, in
accordance with condition (a) or (b) below. A copy of the NOT must be provided to the
operator of any MS4 receiving the discharge in accordance with Section II.F.1. above.
Operators of regulated construction activities who are not required to submit an NOI must
remove the original site notice, and the new operator must post the required site notice prior
to the transfer of operational control, in accordance with condition (a) or (b) below. A copy
of the completed site notice must be provided to the operator of any MS4 receiving the
discharge, in accordance with Section II.F.3. above.
A transfer of operational control occurs when either of the following criteria is met:
(a)
Another operator has assumed control over all areas of the site that have not been
finally stabilized; and all silt fences and other temporary erosion controls have either
been removed, scheduled for removal as defined in the SWP3, or transferred to a new
operator, provided that the permitted operator has attempted to notify the new
operator in writing of the requirement to obtain permit coverage. Record of this
notification (or attempt at notification) shall be retained by the operator in
accordance with Part VI of this permit. Erosion controls that are designed to remain
in place for an indefinite period, such as mulches and fiber mats, are not required to
be removed or scheduled for removal.
(b)
A homebuilder has purchased one or more lots from an operator who obtained
coverage under this general permit for a common plan of development or sale. The
homebuilder is considered a new operator and shall comply with the requirements
listed above, including the development of a SWP3 if necessary. Under these
circumstances, the homebuilder is only responsible for compliance with the general
permit requirements as they apply to lot(s) it has operational control over, and the
original operator remains responsible for common controls or discharges, and must
amend its SWP3 to remove the lot(s) transferred to the homebuilder.
Page 21
Section G.
Waivers from Coverage
The executive director may waive the otherwise applicable requirements of this general permit for
storm water discharges from small construction activities under the terms and conditions described
in this section.
1.
Waiver Applicability and Coverage
Operators of small construction activities may apply for and receive a waiver from the
requirements to obtain authorization under this general permit, where all of the following
conditions are met. This waiver from coverage does not apply to non-storm water
discharges. The operator must insure that any non-storm water discharges are either
authorized under a separate permit or authorization, or are not considered to be a wastewater.
2.
(a)
the calculated rainfall erosivity (R) factor for the entire period of the construction
project is less than five (5);
(b)
the operator submits to the TCEQ a signed waiver certification form, supplied by the
executive director, certifying that the construction activity will commence and be
completed within a period when the value of the calculated rainfall erosivity R factor
is less than five (5); and
(c)
the waiver certification form is postmarked for delivery to the TCEQ at least two (2)
days before construction activity begins.
Steps to Obtaining a Waiver
The construction site operator may calculate the R factor to request a waiver using the
following steps:
(a)
Estimate the construction start date and the construction end date. The construction
end date is the date that final stabilization will be achieved.
(b)
Find the appropriate Erosivity Index (EI) zone in Appendix B of this permit.
(c)
Find the EI percentage for the project period by adding the results for each period of
the project using the table provided in Appendix D of this permit, in EPA Fact Sheet
2.1, or in USDA Handbook 703, by subtracting the start value from the end value to
find the percent EI for the site.
(d)
Refer to the Isoerodent Map (Appendix C of this permit) and interpolate the annual
isoerodent value for the proposed construction location.
(e)
Multiply the percent value obtained in Step (c) above by the annual isoerodent value
obtained in Step (d). This is the R factor for the proposed project. If the value is less
than 5, then a waiver may be obtained. If the value is five (5) or more, then a waiver
may not be obtained, and the operator must obtain coverage under Part II.E.2. of this
permit.
Page 22
Alternatively, the operator may calculate a site-specific R factor utilizing the following
online calculator: http://ei.tamu.edu/index.html, or using another available resource.
The waiver certification form is not required to be posted at the small construction site.
3.
Effective Date of Waiver
Operators of small construction activities are provisionally waived from the otherwise
applicable requirements of this general permit two (2) days from the date that a completed
waiver certification form is postmarked for delivery to TCEQ.
4.
Activities Extending Beyond the Waiver Period
If a construction activity extends beyond the approved waiver period due to circumstances
beyond the control of the operator, the operator must either:
Section H.
1.
(a)
recalculate the rainfall erosivity (R) factor using the original start date and a new
projected ending date, and if the R factor is still under five (5), submit a new waiver
certification form at least two (2) days before the end of the original waiver period;
or
(b)
obtain authorization under this general permit according to the requirements
delineated in either Part II.E.2. or Part II.E.3. at least two (2) days before the end of
the approved waiver period.
Alternative TPDES Permit Coverage
Individual Permit Alternative
Any discharge 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). Applications for individual permit coverage should be submitted at
least three hundred and thirty (330) days prior to commencement of construction activities to
ensure timely issuance.
2.
Individual Permit Required
The executive director may suspend an authorization or deny an NOI in accordance with the
procedures set forth in 30 TAC Chapter 205 (relating to General Permits for Waste
Discharges), including the requirement that the executive director provide written notice to
the permittee. The executive director may require an operator of a construction site,
otherwise eligible for authorization under this general permit, to apply for an individual
TPDES permit in the following circumstances:
(a)
the conditions of an approved total maximum daily load (TMDL) limitation or
TMDL implementation plan on the receiving stream;
Page 23
(b)
the activity being determined to cause a violation of water quality standards or being
found to cause, or contribute to, the loss of a designated use of surface water in the
state: and
(c)
any other consideration defined in 30 TAC Chapter 205 (relating to General Permits
for Waste Discharges) including 30 TAC '205.4(c)(3)(D), which allows the
commission to deny authorization under the general permit and require an individual
permit if a discharger Ahas been determined by the executive director to have been
out of compliance with any rule, order, or permit of the commission, including nonpayment of fees assessed by the executive director.@
Additionally, the executive director may cancel, revoke, or suspend authorization to
discharge under this general permit based on a finding of historical and significant
noncompliance with the provisions of this general permit, relating to 30 TAC §60.3 (Use of
Compliance History). Denial of authorization to discharge under this general permit or
suspension of a permittee’s authorization under this general permit shall be done according
to commission rules in 30 TAC, Chapter 205 (relating to General Permits for Waste
Discharges).
3.
Section I.
Any discharge eligible for authorization under this general permit may alternatively be
authorized under a separate general permit according to 30 TAC Chapter 205 (relating to
General Permits for Waste Discharges), if applicable.
Permit Expiration
1.
This general permit is issued for a term not to exceed five (5) years. All active discharge
authorizations expire on the date provided on page one (1) of this permit. Following public
notice and comment, as provided by 30 TAC '205.3 (relating to Public Notice, Public
Meetings, and Public Comment), the commission may amend, revoke, cancel, or renew this
general permit.
2.
If the executive director publishes a notice of the intent to renew or amend this general
permit before the expiration date, the permit will remain in effect for existing, authorized
discharges until the commission takes final action on the permit. Upon issuance of a
renewed or amended permit, permittees may be required to submit an NOI within 90 days
following the effective date of the renewed or amended permit, unless that permit provides
for an alternative method for obtaining authorization.
3.
If the commission does not propose to reissue this general permit within 90 days before the
expiration date, permittees shall apply for authorization under an individual permit or an
alternative general permit. If the application for an individual permit is submitted before the
expiration date, authorization under this expiring general permit remains in effect until the
issuance or denial of an individual permit. No new NOIs will be accepted nor new
authorizations honored under the general permit after the expiration date.
Part III. Storm Water Pollution Prevention Plans (SWP3)
Storm water pollution prevention plans must be prepared to address discharges authorized under Parts II.E.2.
and II.E.3. that will reach Waters of the United States, including discharges to MS4s and privately owned
Page 24
separate storm sewer systems that drain to Waters of the United States, to identify and address potential
sources of pollution that are reasonably expected to affect the quality of discharges from the construction
site, including off-site material storage areas, overburden and stockpiles of dirt, borrow areas, equipment
staging areas, vehicle repair areas, fueling areas, etc., used solely by the permitted project. The SWP3 must
describe the implementation of practices that will be used to minimize to the extent practicable the discharge
of pollutants in storm water associated with construction activity and non-storm water discharges described
in Part II.A.3., in compliance with the terms and conditions of this permit.
Individual operators at a site may develop separate SWP3s that cover only their portion of the project,
provided reference is made to the other operators at the site. Where there is more than one SWP3 for a site,
permittees must coordinate to ensure that BMPs and controls are consistent and do not negate or impair the
effectiveness of each other. Regardless of whether a single comprehensive SWP3 is developed or separate
SWP3s are developed for each operator, it is the responsibility of each operator to ensure compliance with
the terms and conditions of this general permit in the areas of the construction site where that operator has
control over construction plans and specifications or day-to-day operations.
Section A.
Shared SWP3 Development
For more effective coordination of BMPs and opportunities for cost sharing, a cooperative effort by
the different operators at a site is encouraged. Operators must independently obtain authorization,
but may work together to prepare and implement a single, comprehensive SWP3 for the entire
construction site.
1.
The SWP3 must clearly list the name and, for large construction activities, the general permit
authorization numbers, for each operator that participates in the shared SWP3. Until the
TCEQ responds to receipt of the NOI with a general permit authorization number, the SWP3
must specify the date that the NOI was submitted to TCEQ by each operator. Each operator
participating in the shared plan must also sign the SWP3.
2.
The SWP3 must clearly indicate which operator is responsible for satisfying each shared
requirement of the SWP3. If the responsibility for satisfying a requirement is not described
in the plan, then each permittee is entirely responsible for meeting the requirement within the
boundaries of the construction site where they perform construction activities. The SWP3
must clearly describe responsibilities for meeting each requirement in shared or common
areas.
Section B.
1.
Responsibilities of Operators
Secondary Operators and Primary Operators with Control Over Construction Plans and
Specifications
All secondary operators and primary operators with control over construction plans and
specifications must:
(a)
ensure the project specifications allow or provide that adequate BMPs are developed
to meet the requirements of Part III of this general permit;
(b)
ensure that the SWP3 indicates the areas of the project where they have control over
project specifications, including the ability to make modifications in specifications;
Page 25
2.
(c)
ensure all other operators affected by modifications in project specifications are
notified in a timely manner so that those operators may modify their best
management practices as necessary to remain compliant with the conditions of this
general permit; and
(d)
ensure that the SWP3 for portions of the project where they are operators indicates
the name and site-specific TPDES authorization numbers for permittees with the
day-to-day operational control over those activities necessary to ensure compliance
with the SWP3 and other permit conditions. If the party with day-to-day operational
control has not been authorized or has abandoned the site, the person with control
over project specifications is considered to be the responsible party until the
authority is transferred to another party and the SWP3 is updated.
Primary Operators with Day-to-Day Operational Control
Primary Operators with day-to-day operational control of those activities at a project that are
necessary to ensure compliance with an SWP3 and other permit conditions must ensure that
the SWP3 accomplishes the following requirements:
Section C.
(a)
meets the requirements of this general permit for those portions of the project where
they are operators;
(b)
identifies the parties responsible for implementation of best management practices
(BMPs) described in the SWP3;
(c)
indicates areas of the project where they have operational control over day-to-day
activities; and
(d)
includes, for areas where they have operational control over day-to-day activities, the
name and site-specific TPDES authorization number of the parties with control over
project specifications, including the ability to make modifications in specifications.
Deadlines for SWP3 Preparation, Implementation, and Compliance
The SWP3 must be prepared prior to obtaining authorization under this general permit, and
implemented prior to commencing construction activities that result in soil disturbance. The SWP3
must be prepared so that it provides for compliance with the terms and conditions of this general
permit.
Section D.
1.
Plan Review and Making Plans Available
The SWP3 must be retained on-site at the construction site or, if the site is inactive or does
not have an on-site location to store the plan, a notice must be posted describing the location
of the SWP3. The SWP3 must be made readily available at the time of an on-site inspection
to: the executive director; a federal, state, or local agency approving sediment and erosion
plans, grading plans, or storm water management plans; local government officials; and the
operator of a municipal separate storm sewer receiving discharges from the site.
Page 26
2.
3.
Section E.
In addition to the requirement to post the NOI, a primary operator of a large construction
activity must post the site notice provided in Attachment 4 of this permit near the main
entrance of the construction site. An operator of a small construction activity seeking
authorization under this general permit and a secondary operator of a large construction
activity must post the site notice required in Part II.E.1., 2., or 3. of this permit in order to
obtain authorization (see Attachments 1, 2, and 3). If the construction project is a linear
construction project (e.g. pipeline or highway), the notices must be placed in a publicly
accessible location near where construction is actively underway. Notices for these linear
sites may be relocated, as necessary, along the length of the project. The notices must be
readily available for viewing by the general public; local, state, and federal authorities; and
contain the following information:
(a)
the site-specific TPDES authorization number for the project if assigned;
(b)
the operator name, contact name, and contact phone number;
(c)
a brief description of the project; and
(d)
the location of the SWP3.
This permit does not provide the general public with any right to trespass on a construction
site for any reason, including inspection of a site; nor does this permit require that permittees
allow members of the general public access to a construction site.
Revisions and Updates to SWP3s
The permittee must revise or update the SWP3 whenever the following occurs:
1.
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;
2.
changing site conditions based on updated plans and specifications, new operators, new areas
of responsibility, and changes in BMPs; or
3.
results of inspections or investigations by site operators, operators of a municipal separate
storm sewer system receiving the discharge, 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 F.

to the site;
(vii)
locations where storm water discharges from the site directly to a surface
water body or a municipal separate storm sewer system; and
(viii) vehicle wash areas.
Where the amount of information required to be included on the map would result in
a single map being difficult to read and interpret, the operator shall develop a series
of maps that collectively include the required information.
(h)
the location and description of support activities authorized under the permittee’s
NOI, including asphalt plants, concrete plants, and other activities providing support
to the construction site that is authorized under this general permit;

Page 28
2.
(j)
a copy of this TPDES general permit, and
(k)
the notice of intent (NOI) and acknowledgement certificate for primary operators of
large construction sites, and the site notice for small construction sites and for
secondary operators of large construction sites.
A description of the best management practices (BMPs) that will be used to minimize
pollution in runoff.
The description must identify the general timing or sequence for implementation. At a
minimum, the description must include the following components:
(a)
(b)
General Requirements
(i)
Erosion and sediment controls must be designed to retain sediment on-site to
the extent practicable with consideration for local topography, soil type, and
rainfall.
(ii)
Control measures must be properly selected, installed, and maintained
according to the manufacturer=s or designer=s specifications.
(iii)
Controls must be developed to minimize the offsite transport of litter,
construction debris, and construction materials.
Erosion Control and Stabilization Practices
The SWP3 must include a description of temporary and permanent erosion control
and stabilization practices for the site, including a schedule of when the practices will
be implemented. Site plans should ensure that existing vegetation is preserved where
it is possible.
(i)
Erosion control and stabilization practices may include but are not limited to:
establishment of temporary or permanent vegetation, mulching, geotextiles,
sod stabilization, vegetative buffer strips, protection of existing trees and
vegetation, slope texturing, temporary velocity dissipation devices, flow
diversion mechanisms, and other similar measures.
(ii)
The following records must be maintained and either attached to or
referenced in the SWP3, and made readily available upon request to the
parties listed in Part III.D.1 of this general permit:
(A)
the dates when major grading activities occur;
(B)
the dates when construction activities temporarily or permanently
cease on a portion of the site; and
(C)
the dates when stabilization measures are initiated.
Page 29
(iii)
(iv)
(c)
Erosion control and stabilization measures must be initiated as soon as
practicable in portions of the site where construction activities have
temporarily ceased. Stabilization measures that provide a protective cover
must be initiated as soon as practicable in portions of the site where
construction activities have permanently ceased. Except as provided in (A)
through (D) below, these measures must be initiated no more than 14 days
after the construction activity in that portion of the site has temporarily or
permanently ceased:
(A)
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.
(B)
Where construction activity on a portion of the site has temporarily
ceased, and earth disturbing activities will be resumed within 21
days, temporary erosion control and stabilization measures are not
required on that portion of site.
(C)
In arid areas, semiarid areas, and areas experiencing droughts where
the initiation of stabilization measures by the 14th day after
construction activity has temporarily or permanently ceased or is
precluded by arid conditions, erosion control and stabilization
measures must be initiated as soon as practicable. Where vegetative
controls are not feasible due to arid conditions, the operator shall
install non-vegetative erosion controls. If non-vegetative controls are
not feasible, the operator shall install temporary sediment controls as
required in Paragraph (D) below.
(D)
In areas where temporary stabilization measures are infeasible, the
operator may alternatively utilize temporary perimeter controls. The
operator must document in the SWP3 the reason why stabilization
measures are not feasible, and must demonstrate that the perimeter
controls will retain sediment on site to the extent practicable. The
operator must continue to inspect the BMPs at the frequency
established in Section III.F.7.(a) for unstabilized sites.
Final stabilization must be achieved prior to termination of permit coverage.
Sediment Control Practices
The SWP3 must include a description of any sediment control practices used to
remove eroded soils from storm water runoff, including the general timing or
sequence for implementation of controls.
(i)
Sites With Drainage Areas of Ten or More Acres
(A)
Sedimentation Basin(s)
Page 30
(B)
(ii)
(1)
A sedimentation 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, and must provide sufficient
storage to contain a calculated volume of runoff from a 2year, 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 offsite areas
and flow from onsite areas that are either undisturbed or have
already undergone permanent stabilization, if these flows are
diverted around both the disturbed areas of the site and the
sediment basin. Capacity calculations shall 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 final
stabilization of the site.
(3)
If a sedimentation basin is not feasible, then the permittee
shall provide equivalent control measures until final
stabilization of the site. In determining whether installing a
sediment basin is feasible, the permittee may consider factors
such as site soils, slope, available area, public safety,
precipitation patterns, 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.
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.
Controls for Sites With Drainage Areas Less than Ten Acres:
(A)
Sediment traps and sediment basins may be used to control solids in
storm water runoff for drainage locations serving less than ten (10)
acres. At a minimum, silt fences, vegetative buffer strips, or
equivalent sediment controls are required for all down slope
boundaries of the construction area, and for those side slope
boundaries deemed appropriate as dictated by individual site
conditions.
(B)
Alternatively, a sediment basin that provides storage for a calculated
volume of runoff from a 2-year, 24-hour storm from each disturbed
Page 31
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.
3.
A Description of Permanent Storm Water Controls
A description of any measures that will be installed during the construction process to
control pollutants in storm water discharges that may occur after construction operations
have been completed must be included in the SWP3. Permittees are only responsible for the
installation and maintenance of storm water management measures prior to final stabilization
of the site or prior to submission of an NOT.
4.
5.
Other Required Controls and BMPs
(a)
Permittees shall minimize, to the extent practicable, the off-site vehicle tracking of
sediments and the generation of dust. The SWP3 shall include a description of
controls utilized to accomplish this requirement.
(b)
The SWP3 must include a description of construction and waste materials expected
to be stored on-site and a description of controls to minimize pollutants from these
materials.
(c)
The SWP3 must include a description of potential pollutant sources from areas other
than construction (such as storm water discharges from dedicated asphalt plants and
dedicated concrete batch plants), and a description of controls and measures that will
be implemented at those sites to minimize pollutant discharges.
(d)
Permittees shall place velocity dissipation devices at discharge locations and along
the length of any outfall channel (i.e., runoff conveyance) to provide a non-erosive
flow velocity from the structure to a water course, so that the natural physical and
biological characteristics and functions are maintained and protected.
(e)
Permittees shall design and utilize appropriate controls to minimize the offsite
transport of suspended sediments and other pollutants if it is necessary to pump or
channel standing water from the site.
Documentation of Compliance with Approved State and Local Plans
(a)
Permittees must ensure that the SWP3 is consistent with requirements specified in
applicable sediment and erosion site plans or site permits, or storm water
management site plans or site permits approved by federal, state, or local officials.
(b)
SWP3s must be updated as necessary to remain consistent with any changes
applicable to protecting surface water resources in sediment erosion site plans or site
permits, or storm water management site plans or site permits approved by state or
local official for which the permittee receives written notice.
Page 32
(c)
6.
7.
If the permittee is required to prepare a separate management plan, including but not
limited to a Water Pollution Abatement Plan or Contributing Zone Plan in
accordance with 30 TAC Chapter 213 (related to the Edwards Aquifer), then a copy
of that plan must be either included in the SWP3 or made readily available upon
request to authorized personnel of the TCEQ. The permittee shall maintain a copy of
the approval letter for the plan in its SWP3.
Maintenance Requirements
(a)
All protective measures identified in the SWP3 must be maintained in effective
operating condition. If, through inspections or other means, the permittee determines
that BMPs are not operating effectively, then the permittee shall perform
maintenance as necessary to maintain the continued effectiveness of storm water
controls, and prior to the next rain event if feasible. If maintenance prior to the next
anticipated storm event is impracticable, the reason shall be documented in the
SWP3 and maintenance must be scheduled and accomplished as soon as practicable.
Erosion and sediment controls that have been intentionally disabled, run-over,
removed, or otherwise rendered ineffective must be replaced or corrected
immediately upon discovery.
(b)
If periodic inspections or other information indicates a control has been used
incorrectly, is performing inadequately, or is damaged, then the operator must
replace or modify the control as soon as practicable after making the discovery.
(c)
Sediment must be removed from sediment traps and sedimentation ponds no later
than the time that design capacity has been reduced by 50%. For perimeter controls
such as silt fences, berms, etc., the trapped sediment must be removed before it
reaches 50% of the above-ground height.
(d)
If sediment escapes the site, accumulations must be removed at a frequency that
minimizes off-site impacts, and prior to the next rain event, if feasible. If the
permittee does not own or operate the off-site conveyance, then the permittee must to
work with the owner or operator of the property to remove the sediment.
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.
Page 33
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 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 III.F.8.(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
III.F.8.(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 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).
Page 34
(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).
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.
8.
The SWP3 must identify and ensure the implementation of appropriate pollution prevention
measures for all eligible non-storm water components of the discharge, as listed in Part
II.A.3. of this permit.
9.
The SWP3 must include the information required in Part III.B. of this general permit.
Part IV. Storm Water Runoff from Concrete Batch Plants
Discharges of storm water 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 storm water runoff from concrete
batch plants are not covered under this general permit, then discharges must be authorized under an
alternative general permit or 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.
Section A.
1.
Benchmark Sampling Requirements
Operators of concrete batch plants authorized under this general permit must sample the
storm water runoff from the concrete batch plants according to the requirements of this
Page 35

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 storm water
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 storm water discharge occurred at least once following
submission of the NOI or following the date that automatic authorization was
obtained under Section II.E.2., and prior to terminating coverage.
(*3)
2.
A grab sample shall be collected from the storm water 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.
The permittee must 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.
Page 36
The operator’s investigation must identify the following:
(a)
any additional potential sources of pollution, such as spills that might have occurred,
(b)
necessary revisions to good housekeeping measures that are part of the SWP3,
(c)
additional BMPs, including a schedule to install or implement the BMPs, and
(d)
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 storm water runon to the permitted facility,
by laboratory analyses of samples of storm water run-off from adjacent non-industrial areas,
or by identifying the pollutant is a naturally occurring material in soils at the site.
Section B.
Best Management Practices (BMPs) and SWP3 Requirements
Minimum Storm Water Pollution Prevention Plan (SWP3) Requirements – The following are
required in addition to other SWP3 requirements listed in this general permit (including, but not
limited to Part III.F.7. of this permit):
1.
Description of Potential Pollutant Sources - The SWP3 must provide a description of
potential sources (activities and materials) that may reasonably be expected to affect the
quality of storm water discharges associated with concrete batch plants authorized under this
permit. The SWP3 must describe practices that that will be used to reduce the pollutants in
these discharges to assure compliance with this general permit, including the protection of
water quality, and must ensure the implementation of these practices.
The following must be developed, at a minimum, in support of developing this description:
(a)
Drainage – The site map must include the following information:
(1)
the location of all outfalls for storm water discharges associated with
concrete batch plants that are authorized under this permit;
(2)
a depiction of the drainage area and the direction of flow to the outfall(s);
(3)
structural controls used within the drainage area(s);
(4)
the locations of the following areas associated with concrete batch plants that
are exposed to precipitation: vehicle and equipment maintenance activities
(including fueling, repair, and storage areas for vehicles and equipment
scheduled for maintenance); areas used for the treatment, storage, or disposal
Page 37
of wastes; liquid storage tanks; material processing and storage areas; and
loading and unloading areas; and
(5)
2.
the locations of the following: any bag house or other dust control device(s);
recycle/sedimentation pond, clarifier or other device used for the treatment of
facility wastewater (including the areas that drain to the treatment device);
areas with significant materials; and areas where major spills or leaks have
occurred.
(b)
Inventory of Exposed Materials – A list of materials handled at the concrete batch
plant that may be exposed to storm water and that have a potential to affect the
quality of storm water discharges associated with concrete batch plants that are
authorized under this general permit.
(c)
Spills and Leaks - A list of significant spills and leaks of toxic or hazardous
pollutants that occurred in areas exposed to storm water and that drain to storm water
outfalls associated with concrete batch plants authorized under this general permit
must be developed, maintained, and updated.
(d)
Sampling Data - A summary of existing storm water discharge sampling data must
be maintained, if available.
Measures and Controls - The SWP3 must include a description of management controls to
regulate pollutants identified in the SWP3’s “Description of Potential Pollutant Sources”
from Part IV.B.1.(a) of this permit, and a schedule for implementation of the measures and
controls. This must include, at a minimum:
(a)
(b)
Good Housekeeping - Good housekeeping measures must be developed and
implemented in the area(s) associated with concrete batch plants.
(1)
Operators must prevent or minimize the discharge of spilled cement,
aggregate (including sand or gravel), settled dust, or other significant
materials from paved portions of the site that are exposed to storm water.
Measures used to minimize the presence of these materials may include
regular sweeping or other equivalent practices. These practices must be
conducted at a frequency that is determined based on consideration of the
amount of industrial activity occurring in the area and frequency of
precipitation, and shall occur at least once per week when cement or
aggregate is being handled or otherwise processed in the area.
(2)
Operators must prevent the exposure of fine granular solids, such as cement,
to storm water. Where practicable, these materials must be stored in enclosed
silos, hoppers or buildings, in covered areas, or under covering.
Spill Prevention and Response Procedures - Areas where potential spills that can
contribute pollutants to storm water runoff, and the drainage areas from these
locations, must be identified in the SWP3. Where appropriate, the SWP3 must
specify material handling procedures, storage requirements, and use of equipment.
Page 38
Procedures for cleaning up spills must be identified in the SWP3 and made available
to the appropriate personnel.
3.
(c)
Inspections - Qualified facility personnel (i.e., 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 storm water at the site, including
material handling areas, above ground storage tanks, hoppers or silos, dust
collection/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.
(d)
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 storm water pollution prevention, with the provisions of the
SWP3. The frequency of training must be documented in the SWP3, and at a
minimum, must consist of one training prior to the initiation of operation of the
concrete batch plant.
(e)
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 storm water 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.
(f)
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.
Comprehensive Compliance Evaluation – At least once per year, one or more qualified
personnel (i.e., 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.
(a)
Visual examination of all areas draining storm water 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/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
Page 39
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.
Section C.
(b)
Based on the results of the evaluation, the following must be revised as appropriate
within two weeks of the evaluation: the description of potential pollutant sources
identified in the SWP3 (as required in Part IV.B.1., “Description of Potential
Pollutant Sources”); and pollution prevention measures and controls identified in the
SWP3 (as required in Part IV.B.2., “Measures and Controls”). The revisions may
include a schedule for implementing the necessary changes.
(c)
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.
(d)
The Comprehensive Compliance Evaluation may substitute for one of the required
inspections delineated in Part IV.B.2.(c) of this general permit.
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 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 V of this general permit.
Part V. Concrete Truck Wash Out Requirements
This general permit authorizes the wash out of concrete trucks at construction sites regulated under Sections
II.E.1., 2., and 3. of this general permit, provided the following requirements are met. Authorization is
limited to the land disposal of wash out water from concrete trucks that are associated with off-site
production facilities. Wash out water associated with on-site concrete production facilities must be
authorized under a separate TCEQ general permit or individual permit.
1.
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.
2.
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.
3.
Wash out of concrete trucks during rainfall events shall be minimized. The direct discharge
Page 40
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.
4.
The discharge of wash out water shall not cause or contribute to groundwater contamination.
5.
If a SWP3 is required to be implemented, the SWP3 shall include concrete wash out areas on
the associated map.
Part VI. Retention of Records
The permittee must retain the following records for a minimum period of three (3) years from the date that a
NOT is submitted as required by Part II.E.3. For activities in which an NOT is not required, records shall be
retained for a minimum period of three (3) years from the date that the operator terminates coverage under
Section II.F.3. of this permit. Records include:
1.
A copy of the SWP3;
2.
All reports and actions required by this permit, including a copy of the construction site
notice;
3.
All data used to complete the NOI, if an NOI is required for coverage under this general
permit; and
4.
All records of submittal of forms submitted to the operator of any MS4 receiving the
discharge and to the secondary operator of a large construction site, if applicable.
Part VII. Standard Permit Conditions
1.
The permittee has a duty to comply with all permit conditions. Failure to comply with any permit
condition is a violation of the 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.
2.
Authorization under this general permit may be suspended or revoked for cause. Filing a notice of
planned changes or anticipated non-compliance by the permittee does not stay any permit condition.
The permittee must furnish to the executive director, upon request and within a reasonable time, any
information necessary for the executive director to determine whether cause exists for revoking,
suspending, or terminating authorization under this permit. Additionally, the permittee must provide
to the executive director, upon request, copies of all records that the permittee is required to maintain
as a condition of this general permit.
3.
It is not a defense for a discharger in an enforcement action that it would have been necessary to halt
or reduce the permitted activity to maintain compliance with the permit conditions.
4.
Inspection and entry shall be allowed under Texas Water Code Chapters 26-28, Texas Health and
Safety Code ''361.032-361.033 and 361.037, and 40 Code of Federal Regulations (CFR)
'122.41(i). The statement in Texas Water Code '26.014 that commission entry of a facility shall
occur according to an establishment's rules and regulations concerning safety, internal security, and
Page 41
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.
5.
The discharger is subject to administrative, civil, and criminal penalties, as applicable, under Texas
Water Code ''26.136, 26.212, and 26.213 for violations including but not limited to the following:
a.
negligently or knowingly violating the federal Clean Water Act (CWA), ''301, 302, 306,
307, 308, 318, or 405, or any condition or limitation implementing any sections in a permit
issued under CWA, '402, or any requirement imposed in a pretreatment program approved
under CWA, ''402(a)(3) or 402(b)(8);
b.
knowingly making any false statement, representation, or certification in any record or other
document submitted or required to be maintained under a permit, including monitoring
reports or reports of compliance or noncompliance.
6.
All reports and other information requested by the executive director must be signed by the person
and in the manner required by 30 TAC '305.128 (relating to Signatories to Reports).
7.
Authorization under this general permit does not convey property or water rights of any sort and
does not grant any exclusive privilege.
Part VIII. Fees
1.
A fee of must be submitted along with the NOI:
a.
b.
$325 if submitting a paper NOI, or
$225 if submitting a NOI electronically.
2.
Fees are due upon submission of the NOI. An NOI will not be declared administratively complete
unless the associated fee has been paid in full.
3.
No separate annual fees will be assessed. The Water Quality Annual fee has been incorporated into
the NOI fees as described above.

b.
Vertical face on longitudinal axis, not more than 1/4-inch in 10'-0".
4.
Clean forms after each use and coat with form release agent as often as required to ensure separation from
concrete without damage.
B.
Reinforcement: Fasten reinforcing bars or welded wire fabric (if required) accurately and securely in place with
suitable supports and ties. Remove from reinforcement all dirt, oil, loose mill scale, rust, and other substances that
will prevent proper bonding of the concrete to the reinforcement.
C.
Concrete Placement
1.
Mix and place concrete when the air temperature in the shade and away from artificial heat is a minimum
of 35 degrees F and rising. Hot and cold weather concreting shall be in accordance with ACI 305.1 (hot
weather) and 306.1 (cold weather).
2.
Do not place concrete until base material and forms have been checked for alignment and grade. Concrete
shall not be placed around manholes or other structures until they are at required finish elevation and
alignment.
3.
Place concrete using methods that prevent segregation of mix. Consolidate concrete along face of forms
and adjacent to transverse joints with internal vibrator. Keep vibrator away from joint assemblies, reinforcement, or side forms. Consolidate with care to prevent dislocation of reinforcing, dowels, and joint devices.
4.
Deposit and spread concrete in continuous operation between transverse joints, as far as possible. If interrupted for more than 1/2 hour, place construction joint.

dislodging of aggregates. This will typically be from 1 hour in hot weather to 4 hours in cold
weather after completing finishing of slab in that joint location.
3)
Provide at least two “Soff-Cut” saws on site with blades capable of achieving the required
depth of saw cut.
4)
Extend sawed joint to the slab boundaries and abutments, including columns, drains, and
other penetrations in the path of a defined joint. Implement methods and timing of the saw
cut beyond the limits of the Soff-Cut saw reach to provide a consistent depth of cut with minimal raveling of joint edges.
2.
Construction Joints: Place construction joints at end of placements and at locations where placement operations are stopped for period of more than 1/2 hour. Construct joints in accordance with details shown.
E.
Isolation and Fixed Object Joints: Construct joint at locations and in accordance with details shown.
