Storm Water Pollution Prevention Plans you can be SURE about!
Fast, compliant SWPPP plans for Texas Construction projects & industrial facilities.
Storm Water Pollution Prevention Plan (SWPPP)
A Storm Water Pollution Prevention Plan (SWPPP) is a required document for construction and industrial sites that outlines how stormwater runoff will be controlled to prevent pollution and comply with EPA and Texas Commission on Environmental Quality (TCEQ) regulations.
This page provides a high-level overview of Texas SWPPP Plan requirements. For detailed guidance, explore the specific service pages linked below.

Construction vs Industrial SWPPP (Quick Overview)
In Texas, SWPPP Plans fall into two main categories:
Construction SWPPP (TXR150000)
Required for construction activities that disturb one acre or more of land.
- Focuses on erosion and sediment control
- Temporary (active only during construction)
- Requires frequent inspections (Weekly or Bi-Weekly + rain events)
- Requires Notice of Intent (NOI) filing for sites disturbing 5 acres or more
Industrial SWPPP (TXR050000 / MSGP)
Required for industrial facilities with stormwater exposure.
- Focuses on pollutant exposure and runoff control
- Ongoing compliance (not temporary)
- Requires monitoring and sampling of outfalls
- Includes employee training and reporting

What's Included In A SWPPP Plan?
- Site map and facility description
- Drainage maps and flow patterns
- Best Management Practices (BMPs)
- Pollution Prevention controls
- Inspection Procedures
- Documentation and recordkeeping
Texas SWPPP Plan Cost
- Small Construction Projects (less than 5 acres disturbed): $500 - $1500
- Large Construction Projects (greater than 5 acres disturbed): $1500 - $3500
- Very Large Construction Projects (greater than 20 acres disturbed): $5000 and up
*Costs vary based on site size, complexity, and additional regulatory requirements.
SWPPP Requirements in Texas
SWPPPs must comply with:
- TCEQ Construction General Permit (TXR 150000)
- TCEQ Multi-Sector General Permit (TXR 050000)
- EPA Construction General Permit
Failure to comply can result in:
Fines and penalties – Project Delays
Enforcement actions – Increased Scrutiny
Frequently Asked Questions
Do I need a SWPPP in Texas?
Yes — if your project disturbs 1 acre or more, you are required to have a SWPPP under the TCEQ Construction General Permit (TXR150000).
You may also need a SWPPP if:
- Your project is part of a common plan of development
- You operate an industrial facility with stormwater exposure
- A city, county, or HOA requires it (even under 1 acre)
If you’re unsure, it’s best to verify before starting work — fines and delays can happen quickly without proper coverage.
What is the difference between Construction SWPPPP (TXR 150000) and Industrial MSGP SWPPP (TXR 050000)?
These are two different stormwater permits in Texas:
- TXR150000 (Construction SWPPP)
Applies to construction sites disturbing 1 acre or more
Focuses on erosion and sediment control
Temporary — only active during construction - TXR050000 (Industrial / MSGP SWPPP)
Applies to industrial facilities
Focuses on pollutant exposure and runoff
Ongoing — requires continuous compliance, inspections, and sampling
In short:
Construction = temporary site control
Industrial = ongoing facility compliance
How long does a SWPPP take to prepare?
Construction SWPPPs can be completed within:
- 3 business days for small/simple sites
- 5–10 business days for large or complex projects
- 10+ days for large or complex sites
Construction SWPPPs can be completed within:
- 3-5 weeks for simple industrial sites
- 4-6 weeks for facilities of moderate size or complexity
- 6-10+ weeks for the largest or most complex industrial facilities
Timeline depends on:
- Site size and layout
- Drainage complexity
- Project phasing
- How quickly plans and details are provided
Fast turnaround is possible when all required information is available upfront. We also offer expedited service when requested.
How often are SWPPP inspections required?
Inspection frequency depends on the type of SWPPP:
- Construction SWPPP (TXR150000):
- Every 7 or 14 days, depending on permit requirements
- After qualifying rainfall events (typically 0.5 inches or more)
- Industrial SWPPP (TXR050000 / MSGP):
- Routine facility inspections (often monthly or quarterly)
- Quarterly visual assessments of stormwater discharges
- Additional inspections based on sector requirements
All inspections must be documented and kept on-site or readily available.
Missing inspections is one of the most common violations.
What happens if I don't have a SWPPP Plan?
Operating without a required SWPPP can lead to:
- Fines and penalties
- Stop-work orders
- Project delays
- Increased inspections from regulators
In Texas, both TCEQ and EPA can enforce violations.
Even a short delay in compliance can impact your schedule and budget — which is why most contractors get coverage in place before breaking ground.
What is a Common Plan of Development?
A common plan of development refers to multiple construction activities that are part of a larger overall project, even if each individual site is under 1 acre.
For example:
- A subdivision built in phases
- Multiple commercial lots in one development
- Separate contractors working on connected parcels
If the total disturbed area exceeds 1 acre, a SWPPP is typically required.
This is one of the most commonly misunderstood rules.
Can a city, county, or HOA require a SWPPP on projects disturbing less than 1 acre?
Yes — and this happens more often than most people realize.
Even if your project is under the 1-acre threshold:
- Cities and counties may have stricter local ordinances
- HOAs or developers may require SWPPPs as part of project approval
These requirements are in addition to state and federal rules, not replacements.
👉 Bottom line: Always check local requirements before starting work.
Who is responsible for SWPPP compliance?
The site operator is legally responsible for SWPPP compliance.
This is typically:
- The general contractor
- The property owner
- The developer
- Or a combination, depending on project structure
Responsibilities include:
- Ensuring the SWPPP is developed and implemented
- Installing and maintaining BMPs
- Conducting inspections
- Keeping proper documentation
Even if you hire a consultant, you are still ultimately responsible for compliance.
