Background / History
All Storm Water Regulations stem from the CLEAN
WATER ACT (1972)
¾ Section 303 – Established Water Quality Standards
¾ Section 401 – Regulates Water Quality Impacts
¾ Section 402 – Established National Pollutant Discharge Elimination
System (NPDES)
¾ Section 404 – Regulates Impacts to U.S. Waters / Wetlands
(USACE – United States Army Corp of Engineers)
NPDES (EPA) delegated to Texas in 1998.
Texas Pollutant Discharge Elimination System
(TPDES - TCEQ) on March 5, 2003

WHAT IS STORM WATER?
Storm Water is water runoff resulting from a storm (rain) or
snowmelt, which can enter surface waters in Texas.
WHY ARE STORM WATER DISCHARGES REGULATED?
Storm water discharges often contain pollutants in amounts
that could reduce water quality. The primary pollutants of
concern from construction activities:
Silt
Sediment
Oils and Grease
Vehicle Fluids
Trash
Debris
Version 072814

Construction Activity
What is considered “CONSTRUCTION ACTIVITY”?
Clearing
Grading
Excavating
Similar Activities that Disturb / Expose Soil
(Demolition, Cut / Fill areas, Spoils Areas……..)
What is NOT considered “CONSTRUCTION ACTIVITY”?
Routine Maintenance of Conveyances
Routine Grading of Existing Roads
Land Disturbances for Agricultural Activities
Version 072814

Who Applies for TPDES CGP Coverage?
SWP3 and NOI’s are necessary for:
¾ Operators with “OPERATIONAL CONTROL”
¾ Operators with “DAY-TO-DAY CONTROL”
NOTE – SWP3’s may be combined to cover numerous Operators, but NOI’s are opened
individually for each Operator
Operators may include:
¾
¾
¾
¾
Landowners / Developers
General Contractors
Homebuilders (includes Custom Homebuilders)
Some circumstances may require Subcontractor coverage
Version 072814

Operator Definition

TPDES definition of “OPERATOR”
¾
Primary Operator – The person or persons associated with a large or
small construction activity that meets either of the following two criteria:
a) having on-site operational control over construction plans and
specifications, including the ability to make modifications; or
b) having day-to-day operational control over those activities necessary
to ensure compliance with the SWP3
¾
Secondary Operator – The person or entity, often the property owner,
whose operation control is limited to:
a) the employment of other operators, such as the general contractor, to
perform or supervise construction activities; or
b) the ability to approve or disapprove changes to plans and specs, but
who does not have day-to-day onsite operational control over
construction activities onsite
Version 072814

What Else Can the
TPDES CGP Authorize?
Storm water from activities directly supporting a
permitted construction site:
¾
¾
¾
¾
¾
Rock crushing
Concrete batch plants
Asphalt batch plants
Borrow areas / pits
Material storage / disposal area
Supporting activities must be:

Self Audit

You can do a self audit by looking at the following:
¾ SIGNAGE
• Is there a sign for every permitted section at each section entrance?
(sections permitted together can have one sign at the main entrance)
• Does it have the Construction Site Notice (CSN) with correct information?
• Does it have a rain gauge?
¾ SWPPP
• Where is the SWPPP located? (trailer, offsite, clearly marked and visible)
• Are the Certification and Delegation pages signed?
• Is there a copy of the signed NOI or Small CSN?
• Is there a copy of the Permit Number and Certificate?
• Is there a construction sequence of events page? Is it being updated?
• Does it have up-to-date site maps?
• Does it have all the signed copies of the inspection reports / corrective actions?
• If there are recurring issues on the reports, is there a plan of action to take care
of them? (sweeping schedules, maintenance schedules, appropriate maintenance
log sheet for the weights of silt removed from E/S controls, etc.)
• Review for special inspection schedules or required inspector certifications
• If Edwards Aquifer site, is there a copy of the WPAP / CZP / SCS and approval letter in the
SWP3? Note: Must be kept with SWPPP at ALL times.

EPA – Expedited Settlement Offer (ESO)
Currently, EPA can administratively assess a penalty of up to
$37,500 for Class 1 violations and up to $187,500 for Class 2
violations (PER VIOLATION, PER DAY).
The Expedited Settlement Offer (ESO) was not developed to
replace the current penalties, but to augment them. In order to
be eligible for the ESO the following criteria must be met:
¾ Construction sites that are 50 acres or less
¾ Sites where the penalty calculated via the ESO worksheet is no
more than $15,000
¾ Sites where there is no evidence of significant environmental
impact (e.g. turbidity in the receiving water / offsite discharge)
¾ Sites where the operator is a first-time violator
¾ Sites where there is no evidence of non-allowable storm water
discharges (e.g. process wastewater discharge, such as truck washing
or discharge from a concrete batch plant operation)
Version 072814
38
46 possible violations on the
ESO worksheet
¾ 29 paperwork related
¾ 17 field related
If respondent does not wish to
settle the violations through
the ESO process, the
Respondent should arrange a
Show Cause Hearing with EPA
(this meeting is to show how the
Respondent has complied with the
CWA / regulations and why EPA
should not take further enforcement
action against respondent for the
cited violations).

Outfalls / Headwalls
Concentrated flows leaving the limits of
construction. They may include a pipe, a headwall
(with or without dissipaters), or be at the end of a
drainage channel.
This is the first place the regulators look for offsite
discharges. They also look downstream for
sediment deposition.
All concrete portions of outfalls should be clear of
vegetation, trash, sediment, and debris. There
should be no evidence of offsite discharges.
Version 030513
43
Outfalls / Headwalls
Version 030513
44
Drainage Channels
Swales and drainage channels are channels lined
with vegetation, riprap/ concrete, etc. that are used
to channel and filter runoff reducing erosion.
Dense vegetation in swales provides filtration to
help improve water quality.
They should be free of trash / debris and sediment;
all headwalls should also be free of sediment,
vegetation and trash / debris.
Version 030513
45
Drainage Channels
Version 030513
46
Stabilized Construction Exit (SCE)
Used to facilitate the removal of sediment from
construction equipment exiting the construction
site.
Most consist of gravel, crushed stone or other
rock-like material at the main entrance to the site.
Prevent erosion and rutting caused by vehicle
tires while removing sediment and mud from the
vehicle’s tires.

Silt Fence
Silt fences are made of filter fabric or woven plastic
stretched over a wire fence supported by posts
(wood stakes or T-posts) for temporary sediment
and erosion control.
Used to redirect silt from entering drainage ways and
receiving waters.
When silt fencing is used in the J-hook capacity, it
will slow water down and act as a temporary
sedimentation basin, allowing sediment to settle
Version 030513

Silt Fence
Some J-hooks or half-moon sections of silt fence could have
decreased or prevented the amount of sediment that overtopped
this silt fence.
Version 030513
51
Rock Berms
Rock berms are small dams of bull rock wrapped in
wire and placed in areas to slow the flow of the
storm water and promote sediment distribution.
They should be placed at the toe of the slope on
each side.
They should be clean and drain properly. Runoff
should not be going around it and they should be
free of sediment, trash, vegetation, and debris.

Inlet Protection
Storm drain inlet protection is a sediment-trapping
filter placed around the inlet or drain.
This control minimizes sediment from entering the
storm drainage structure and keeps downstream
conveyances from silting-in.
Prevents trash and debris from getting in the
storm drain system.

Ponds
Used to prevent flooding, erosion and pollution of creeks
and lakes. There are four main types of storm water
ponds:
¾Detention pond
¾Water quality pond (Filtration pond / Sedimentation Pond)
¾Retention pond / Irrigation pond
¾Wet pond
Ponds need to be free of trash, debris and excess
vegetation and sediment. Also check for erosion on the
pond slopes and around outlets / outfalls. The sand
portion of water quality pond should be free of sediment
and vegetation to allow for proper storm water treatment.

Concrete Washout Area (CWO)
Concrete washouts are used to contain concrete and liquids
when the chutes of concrete mixers and hoppers of
concrete pumps are rinsed out after delivery.
Washout wastewater is corrosive and caustic, which can
leach into the ground and contaminate groundwater.
Installing concrete washout facilities not only minimizes
pollution, but also is a matter of good housekeeping on the
construction site.
CRI recommends that all designated concrete washout
areas be lined

Tree Protection
Importance of tree protection (fencing or
planking):
¾ Helps stabilize the soil, which prevents erosion
¾ Allows infiltration of water
¾ Protects against diseases (Oak Wilt)
Some Municipalities require tree protection to be
placed at the drip line of the tree.
Size and species determines whether they will be
protected in most municipalities.
