Stormwater runoff Outfall at an Industrial Facility
Who This Applies To (Am I Affected?)
The TPDES MSGP regulation applies to Texas facilities that conduct "industrial activities" exposed to rain or stormwater runoff and their associated SIC (Standard Industrial Classification) or NAICS (North American Industry Classification System) code is listed under Part II Section A. 1. (b) of the TXR050000.
Common facility types we support that required a SWPPP: (Who we Help)
- Manufacturing and processing facilities
- Machine shops
- Metal fabrication shops/facilities
- Blasting and Coating facilities
- Ready-mix concrete and batch plants or other concrete products facilities
- Warehouses with outdoor storage
- Logistics facilities
- Equipment yards and industrial service facilities
- Oilfield Support facilities
- Scrap Yards
- Auto Salvage Yards
- Food & kindred products facilities
- And many other industrial sectors
You are required to comply if:
- Your facility falls under a listed industrial SIC or NAICS code;
- You store materials, waste, or equipment outdoors; and
- Stormwater leaves your property through a storm drain, ditch, culvert, detention/retention pond overflows, or outfall.
Outdoor Storage at a Manufacturing Facility
Why the Permit and SWPPP are Required?
When it rains, stormwater can pick up oil, metals, sediment, chemicals, debris, and other pollutants from industrial and similar types of sites and carry them into local bayous, creeks, rivers, and drinking water sources.
Because of this, federal and state regulations require certain facilities to
- Control how stormwater flows across their site,
- Prevent pollutants from leaving the property by implementing Best Management Practices (BMPs) through structural and non-structural controls, and
- Document what controls are in place and how they’re maintained.
The Regulatory Background — Simplified:
- The EPA created stormwater rules under the Clean Water Act (CWA) - National Pollutant Discharge Elimination System (NPDES).
- Texas implements these rules through TCEQ’s Texas Pollutant Discharge Elimination System (TPDES) as delegated by the EPA.
- The main permit for stormwater discharges associated with industrial activities is the TPDES Multi-Sector General Permit MSGP(Permit No. TXR050000).
- A Stormwater Pollution Prevention Plan (SWPPP / SWP3) is required to show how your facility complies with this rule.
Why this matters for your facility:
- Cities and counties enforce stormwater rules through their Municipal Separate Storm Sewer System (MS4) permits.
- Local inspectors regularly review SWPPPs, inspection logs, and BMPs. this includes:
- TCEQ Reginal Offices
- City of Houston Industrial Storm Water Program Team
- Harris County Pollution Control Services (PCS)
- The Port of Houston
- San Antonio Water System (SAWS)
- City of Austin – Watershed Protection Department (WPD)
- City of Dallas – Stormwater Management
- Trinity Watershed Management
- City of Corpus Christi - Utilities Department Water Quality
- Or other local municipal agencies / authorities
- Missing or outdated documentation is one of the most common violations
- Having the permit and SWPPP in place shows good faith compliance and reduces enforcement risk
- Avoid Fines and Penalties
This isn’t just paperwork, it’s how regulators determine whether your facility is doing its part to protect local waterways.
To ensure your facility meets current stormwater standards, you can review the official Texas Commission on Environmental Quality (TCEQ) stormwater regulations and permitting requirements:
Multi-Sector General Permit for Industrial Facilities (TXR050000)
EPA Requires the SWPPP Implementation through the CWA
Where facilities Commonly Struggle:
- Old or generic SWPPPs that don’t match the site’s current conditions
- SWPPs that don’t get updated as facility conditions change
- Failure to submit a Notice of Change (NOC) to update the permit
- Failure to renew the permit on TCEQ’s 5-year cycle (2021 was the last cycle)
- Notice of Intents (NOI) not properly filed. We have seen the following, even from other consultants:
- Filing under a No Exposure Certificate (NEC) but not meeting the requirements
- Wrong Outfall coordinates
- Listing the wrong receiving body of water
- Filed under the wrong Industrial Sector
- Entering the incorrect contact information for the permit, DMR, or for the annual fees
- Missing inspection records or corrective action follow-up
- BMPs that exist on paper but not in practice
- Being unprepared when a city or county inspector shows up
All of the above may lead to permit violations and potential penalties by TCEQ or local authorities. Texas stormwater regulations are enforceable under the Texas Water Code, with Administrative Penalties up to $25,000 per day, per violation and Civil Penalties: $50 – $25,000 per day depending on nature and duration of violation. Maintaining proper SWPPP, MSGP permit and documentation helps prevent avoidable enforcement actions.
