Stormwater Permitting and Compliance

Ensure Stormwater Permitting and Compliance Across Texas for Industrial and Construction Sites - Storm Water (and Facility Wastewater Combined with Storm Water) permitting and compliance is required before any industrial or construction activities can commence.

The Critical Importance of Stormwater Compliance in Texas

Under the Clean Water Act (CWA) and the Texas Pollutant Discharge Elimination System (TPDES), Texas strictly regulates stormwater discharges from industrial facilities and construction sites disturbing one acre or more. Operating without the proper permit—or failing to adhere to its stringent conditions—can trigger severe consequences, including costly Notices of Violation (NOVs), stop-work orders, and substantial administrative fines.

Beyond regulatory mandates, proactive stormwater management is vital to preserving Texas’s natural resources. Unmanaged runoff carries sediment, heavy metals, oils, and industrial chemicals directly into our local rivers, lakes, and coastal waters. By partnering with Peace Environmental Services, you protect your business from legal liabilities while actively contributing to a cleaner, more sustainable environment.

Frequently Asked Questions (FAQs)

01When is a Stormwater Pollution Prevention Plan (SWPPP) required in Texas?

Under the TPDES Construction General Permit (TXR150000), a SWPPP is legally required for any construction activity that disturbs one or more acres of land, or is part of a larger common plan of development that will eventually disturb one or more acres. Additionally, operational industrial facilities covered under the Multi-Sector General Permit (TXR050000) are required to maintain and implement a site-specific SWPPP at all times.

02What is the difference between NPDES and TPDES?

The National Pollutant Discharge Elimination System (NPDES) is the federal stormwater and wastewater regulatory program managed by the EPA. The EPA has authorized the State of Texas to administer its own permitting program. This state-level program, managed by the Texas Commission on Environmental Quality (TCEQ), is called the Texas Pollutant Discharge Elimination System (TPDES). While the rules are based on federal EPA standards, operators in Texas will apply for permits and submit reports directly through the TCEQ under the TPDES program.

03How often do I need to conduct stormwater inspections?

Inspection frequency is strictly dictated by your permit type:

  • Construction Sites: You generally have two options under the TCEQ: inspect the site at least once every 7 calendar days, or inspect at least once every 14 calendar days and within 24 hours of a rain event of 0.5 inches or greater.
  • Industrial Facilities: Standard requirements include Routine Facility Inspections (often quarterly), Visual Assessments of stormwater discharges, and an Annual Comprehensive Site Compliance Evaluation.
04Do my stormwater permits ever expire?

Yes. TPDES general permits operate on a five-year renewal cycle. For example, when the state renews the Multi-Sector General Permit or the Construction General Permit, existing permit holders do not automatically retain coverage. If your site is still active, you must submit a renewal Notice of Intent (NOI) and update your SWPPP to reflect any new regulatory requirements introduced in the updated general permit.

05How are Discharge Monitoring Reports (DMRs) submitted to the TCEQ?

The TCEQ requires that stormwater sampling data, benchmark monitoring results, and Discharge Monitoring Reports (DMRs) be submitted electronically. This is done using the EPA’s online NetDMR reporting system. If your facility is required to conduct sampling (such as for hazardous metals or benchmark pollutants), data must typically be uploaded to NetDMR by March 31st of the following year. We manage this entire administrative process for our clients.

06What should I do if my site receives a Notice of Violation (NOV)?

An NOV is a formal warning from the TCEQ or EPA that your facility was found to be out of compliance during an audit or inspection. You must respond quickly—usually within a strict timeframe outlined in the notice—with a formal Corrective Action Plan detailing how you have resolved, or plan to resolve, the specific violations. Ignoring an NOV can trigger escalated enforcement, stop-work orders, and severe administrative fines. If you receive an NOV, contact an environmental compliance expert immediately to help navigate the regulatory response.
