If you are breaking ground on a construction project in Texas, stormwater compliance is not optional. The Texas Commission on Environmental Quality (TCEQ) requires a Stormwater Pollution Prevention Plan, commonly known as a SWPPP, for any construction activity that disturbs one acre or more of land. Fail to comply, and you could face fines up to $32,500 per day per violation.

For Texas contractors and developers, understanding SWPPP compliance is essential to keeping projects on schedule, avoiding costly penalties, and protecting local waterways. This guide breaks down exactly what a SWPPP is, when you need one, what it must include, and how to stay on the right side of TCEQ regulations.
What Is a SWPPP?
A Stormwater Pollution Prevention Plan (SWPPP) is a site-specific document that outlines how a construction project will prevent stormwater runoff from carrying sediment, debris, and pollutants into nearby waterways, storm drains, and municipal separate storm sewer systems (MS4s).
The requirement originates from the federal Clean Water Act, which prohibits the discharge of pollutants into waters of the United States without a permit. In Texas, the Environmental Protection Agency (EPA) has delegated this authority to TCEQ through the Texas Pollutant Discharge Elimination System (TPDES) program. TCEQ administers the Construction General Permit (CGP), designated as permit number TXR150000, which governs stormwater discharges from construction activities statewide.
A SWPPP is not a generic template you can download and file away. It must be tailored to your specific project site, describing actual drainage patterns, soil conditions, and the best management practices (BMPs) you will implement to control erosion and sedimentation throughout the life of the project.
When Does a Texas Construction Site Need a SWPPP?
Texas law requires a SWPPP for construction projects that disturb one acre or more of land. This threshold also applies to projects that disturb less than one acre if they are part of a larger common plan of development or sale that collectively disturbs one acre or more.
In practical terms, most commercial construction, residential subdivisions, road projects, and industrial site development in Texas will trigger the SWPPP requirement. Even grading, clearing, and demolition activities count toward the acreage threshold.
NOI Requirements: When to File with TCEQ
In addition to preparing a SWPPP, some projects require filing a Notice of Intent (NOI) with TCEQ:
- Projects disturbing 5 acres or more: You must file an NOI through TCEQ’s STEERs online system at least 48 hours before construction begins. The filing fee is $225.
- Projects disturbing 1 to 5 acres: You need a SWPPP but not an NOI. Instead, you file a Small Construction Site Notice with TCEQ.
- Projects near impaired waters: Additional requirements may apply if your site discharges to a waterbody on the EPA’s 303(d) impaired waters list or within a watershed with an established Total Maximum Daily Load (TMDL).
Your SWPPP must be prepared and ready before you submit the NOI. TCEQ requires that the plan be in place before any land-disturbing activities begin, not after.
Key Components of a Compliant SWPPP
A Texas SWPPP under the TXR150000 permit must include several critical elements. Missing any one of these during a TCEQ inspection can result in a violation.
| SWPPP requirement | Why TCEQ expects it | Common failure point |
|---|---|---|
| Site description and map | Documents drainage, disturbed acreage, discharge points, and BMP locations | Generic maps that do not match field conditions |
| Erosion and sediment controls | Prevents sediment from leaving the construction site | BMPs installed after grading or not maintained after rain |
| Inspection records | Shows ongoing compliance with the TXR150000 permit | Missing 14-day inspections or 24-hour post-rain inspections |
| Pollution prevention measures | Controls concrete washout, fuel, chemicals, waste, and debris | No designated washout or spill response procedure |
1. Site Description and Assessment
Your SWPPP must document the existing conditions of the project site, including:
- Total project area and the area of land disturbance
- Soil types and their erodibility
- Existing vegetation and topography
- Proximity to surface waters, wetlands, and storm drains
- Drainage patterns and stormwater flow direction
2. Site Map
A detailed site map is required, showing construction boundaries, drainage patterns, locations of all BMPs, areas of soil disturbance, material storage areas, and the locations where stormwater leaves the site (discharge points).
3. Erosion and Sediment Controls (BMPs)
Best management practices are the backbone of every SWPPP. Texas requires both erosion controls (preventing soil from detaching) and sediment controls (capturing soil before it leaves the site). Common BMPs include:
- Silt fences installed along the site perimeter and downslope of disturbed areas
- Sediment basins and traps to capture runoff before it reaches waterways
- Stabilized construction entrances to prevent mud tracking onto public roads
- Erosion control blankets on slopes steeper than 3:1
- Inlet protection on storm drains within and adjacent to the site
- Temporary seeding or mulching on areas that will remain disturbed for more than 14 days
BMPs must be installed before grading begins, not after the first rain event. TCEQ expects controls to be proactive, not reactive.
4. Inspection and Monitoring Schedule
The TXR150000 permit requires regular site inspections to verify that BMPs are installed correctly and functioning as designed:
- Routine inspections: At least once every 14 calendar days
- Rain event inspections: Within 24 hours of any rainfall event producing 0.5 inches or more
- Documentation: Every inspection must be recorded in writing, noting the date, inspector name, conditions observed, BMP status, and any corrective actions taken
Inspection records must be maintained on-site and kept for at least three years after the Notice of Termination (NOT) is filed. TCEQ inspectors can request these records at any time, often without advance notice.
5. Roles and Responsibilities
The SWPPP must clearly identify who is responsible for each aspect of stormwater compliance on the site, including the site operator, the person responsible for BMP installation and maintenance, and the designated inspector. On multi-operator sites, each operator must either develop a separate SWPPP for their portion or be covered under a comprehensive plan that coordinates BMPs across the entire project.
6. Pollution Prevention Measures
Beyond erosion and sediment, your SWPPP must address other potential pollutant sources, such as:
- Concrete washout areas with proper containment
- Fuel and chemical storage with secondary containment and spill kits
- Construction waste and debris management
- Dust control measures during dry conditions
Common SWPPP Violations and Penalties in Texas
TCEQ actively inspects construction sites across Texas, and violations are more common than many contractors realize. The most frequent issues include:
- No SWPPP on site: The plan must be available for review at the construction site at all times. Keeping it in an office across town is not compliant.
- Improperly installed BMPs: Silt fences without proper trenching, missing inlet protection, or sediment basins that were never constructed are common citations.
- Failure to maintain BMPs: Controls that are damaged, full of sediment, or displaced and not repaired within the required timeframe.
- Incomplete or missing inspection records: Skipping required inspections or failing to document them in writing.
- No Notice of Intent filed: Starting construction on a 5+ acre project without filing the required NOI.
- Failure to stabilize inactive areas: Leaving disturbed areas exposed without temporary stabilization for longer than 14 days.
What Are the Penalties?
TCEQ has the authority to impose penalties of up to $32,500 per violation per day of noncompliance. Because each day of a continuing violation counts separately, even a week of noncompliance with a single issue can result in penalties exceeding $200,000.
Beyond state enforcement, the EPA retains federal oversight authority and can pursue additional penalties under the Clean Water Act. Citizen lawsuits are also possible under CWA Section 505, meaning community groups and environmental organizations can take legal action against non-compliant operators.
Even when penalties are not levied immediately, a TCEQ violation can trigger project delays, stop-work orders, and increased regulatory scrutiny on future projects.
How Long Does a SWPPP Stay Active?
Your SWPPP remains active from the date you file your NOI (or Small Construction Site Notice) until you file a Notice of Termination (NOT) with TCEQ. You can file the NOT once:
- All construction activity is complete
- Final stabilization has been achieved (70% uniform vegetative cover or equivalent permanent stabilization on all disturbed areas)
- All temporary BMPs have been removed
For most Texas construction projects, the SWPPP is active for 6 to 18 months. Projects with phased development can remain active significantly longer.

Local Requirements: Cities May Impose Stricter Rules
While TCEQ sets the statewide baseline through the TXR150000 permit, many Texas cities and counties enforce additional stormwater requirements that go beyond state standards. Houston, Austin, San Antonio, Dallas, and their surrounding municipalities often require:
- Pre-construction SWPPP review and approval before permits are issued
- Third-party inspections by certified stormwater professionals
- More frequent inspection schedules than the state minimum
- Additional permit fees and stormwater utility charges
Contractors working in the Houston metro area and Texas Gulf Coast region should verify local requirements with the relevant city or county stormwater department before beginning work. Compliance with the state CGP alone may not satisfy all local ordinances.

Frequently Asked Questions About Texas SWPPP Compliance
What triggers the SWPPP requirement in Texas?
Any construction activity that disturbs one acre or more of land requires a SWPPP under TCEQ’s Construction General Permit (TXR150000). Projects disturbing less than one acre also need one if they are part of a larger common plan of development that totals one acre or more.
How much does a SWPPP cost in Texas?
SWPPP development costs vary based on project size, site complexity, and local requirements. The NOI filing fee with TCEQ is $225 for projects over 5 acres. Contact Projexiv for a free quote on SWPPP development for your specific project.
What happens if I start construction without a SWPPP?
Beginning construction without a required SWPPP is a violation of the TCEQ Construction General Permit. Penalties can reach $32,500 per day, and TCEQ can issue stop-work orders until compliance is achieved.
How often must I inspect my construction site for SWPPP compliance?
TCEQ requires inspections at least every 14 calendar days and within 24 hours of any rainfall event of 0.5 inches or more. All inspections must be documented and records retained for a minimum of three years.
Can I write my own SWPPP?
While there is no licensing requirement to prepare a SWPPP in Texas, the plan must be site-specific, technically accurate, and fully compliant with TXR150000 requirements. A generic or incomplete SWPPP is a common cause of TCEQ violations. Most contractors work with environmental consultants to ensure their plans meet regulatory standards.
Does my SWPPP need to address anything besides erosion?
Yes. A complete SWPPP must also address pollution prevention for concrete washout, fuel and chemical storage, construction waste, and any other potential pollutant sources on site. If your project is near an environmentally sensitive area, additional measures may be required.
