How to Avoid the Most Common TCEQ Stormwater Fines

Nearly every stormwater enforcement action traces back to a handful of administrative failures — not actual pollution events.

Texas Commission on Environmental Quality enforcement actions for stormwater violations follow predictable patterns. Nearly all of them trace back to a handful of administrative failures rather than actual pollution events — which is good news, because paperwork problems are the cheapest kind to fix.

The scale is worth stating plainly. In fiscal year 2025, TCEQ issued more than 19,000 Notices of Violation, referred nearly 2,000 matters to enforcement, entered over 1,100 effective orders, and assessed roughly $13.2 million in administrative penalties across all its programs. Stormwater is a slice of that, but the mechanics below are what turns an inspection into an order.

Here's where operators most often get caught, and what to do about it.

1. Operating Without Permit Coverage

The single most common violation is simple: discharging stormwater without authorization. Construction sites disturbing one or more acres need coverage under the TXR150000 general permit. Industrial facilities in regulated SIC codes need TXR050000 coverage.

How it happens: A project breaks ground before the Notice of Intent is filed. Or a site assumes it falls under the one-acre threshold without accounting for the full “common plan of development” — the total acreage of a phased subdivision, not just the phase currently under construction.

How to avoid it: File the NOI and wait for confirmation of coverage before any earth-moving begins. Calculate disturbed acreage across the entire common plan. For sites between one and five acres, confirm whether you qualify for a low rainfall erosivity waiver rather than assuming you do.

2. No SWPPP, or a SWPPP That Doesn't Match the Site

Every permitted site needs a Stormwater Pollution Prevention Plan. Inspectors don't just check that one exists — they check whether it describes the site in front of them.

How it happens: A boilerplate SWPPP gets purchased or copied from a previous project. The site plan shows controls that were never installed, or the sequence of construction bears no resemblance to what's actually happening. Site conditions change and the SWPPP never gets updated.

How to avoid it: Treat the SWPPP as a living document. When you add a stockpile, relocate a concrete washout, or change the phasing, amend the plan and date the amendment. Keep the current version on site and accessible — an inspector who has to wait for someone to email a PDF from the main office has already formed an impression.

3. Missing or Incomplete Inspection Records

Documentation gaps generate an enormous share of citations, because they're the easiest thing for an inspector to verify.

How it happens: Construction sites need inspections at the required frequency — typically every 14 days, or every seven days plus after rain events of 0.5 inches or more, depending on the option selected. Records get skipped during holidays, staff turnover, or busy stretches. Reports get filled out but never signed. Deficiencies get noted but the corrective action column stays blank.

How to avoid it: Assign one named person responsibility for inspections, with a named backup. Use a rain gauge on site and log readings, so you can demonstrate why a post-storm inspection was or wasn't triggered. Most critically: close the loop. Every noted deficiency needs a documented correction, with a date. An inspection log that identifies problems and never resolves them is worse than no log at all — it's a written record of knowing negligence.

4. Controls Installed Wrong or Not Maintained

How it happens: Silt fence trenched too shallow, or not trenched at all. Inlet protection clogged solid and bypassing. Stabilized construction entrances that have been pounded into mud. Perimeter controls installed downhill of stockpiles rather than around them.

How to avoid it: Install to specification, then maintain. Sediment should be removed from behind silt fence when it reaches roughly one-third to one-half the fence height — don't wait for failure. Repair or replace controls within the timeframe your permit requires after identifying a problem. And remember that a control that's technically present but functionally overwhelmed is still a violation.

5. Concrete Washout and Material Storage Failures

How it happens: Concrete trucks rinse out into an unlined pit, or worse, onto bare ground near a drainage path. Fuel, oil, and chemicals sit outdoors uncovered without secondary containment. Trash and debris migrate off site.

How to avoid it: Designate and sign a proper washout facility, keep it lined and away from drainage features, and service it before it overflows. Store liquids under cover with containment. This is a category where inspectors take photographs, and photographs are hard to argue with.

6. Failure to Stabilize, and Failure to Terminate

How it happens: Work stops on a portion of the site and disturbed soil sits exposed indefinitely. Or the project finishes and nobody files the Notice of Termination — leaving the operator on the hook for a site they no longer control, with permit obligations quietly accruing.

How to avoid it: Initiate stabilization on areas where work has permanently or temporarily ceased within the required timeframe. When the project is genuinely complete and final stabilization is achieved, file the NOT. Coverage does not expire on its own.

7. Industrial-Specific Traps

Facilities under TXR050000 have their own recurring failures: missed benchmark monitoring, missed annual comprehensive site compliance evaluations, unsubmitted Discharge Monitoring Reports, and unaddressed exceedances. The pattern is the same — obligations with deadlines, missed for want of a calendar.

How to avoid it: Build the monitoring and reporting schedule into a compliance calendar with reminders that go to more than one person.

The Underlying Pattern

Notice what nearly every item above has in common. TCEQ enforcement rarely begins with someone catching visible pollution in a waterway. It begins with an inspector opening a binder.

The fines follow from gaps that are visible on paper: no permit, no plan, no records, no follow-through. A site with mediocre controls and immaculate documentation of ongoing correction usually fares far better than a site with good intentions and an empty binder.

Three habits prevent most of it:

1. File before you dig, terminate when you're done. Permit coverage has a beginning and an end, and both require action.
2. Make the paper match the dirt. If the SWPPP and the site disagree, one of them needs to change today.
3. Never leave a deficiency open. Every problem you identify gets a documented fix with a date. Identifying problems is not what gets you fined. Ignoring the ones you identified is.
