In Texas, TCEQ (Texas Commission on Environmental Quality) rolls out the red carpet for industrial stormwater with a special permit: TXR050000.

Wrapped up in the federal Clean Water Act’s TPDES program, this permit is your go-to for nailing stormwater pollution control from your industrial site.

Don’t snooze on this. Check out TCEQ’s official PDF to get the full scoop and stay ahead of the game. TCEQ_txr050000-2021.pdf

Which Facilities are Required to Obtain Permit Coverage?

If you’re in Texas and involved in industrial activities—anything from manufacturing and mining to recycling and power plants—listen up! The MSGP TXR050000 has got you in its sights.

This permit uses Standard Industrial Classification (SIC) or Industrial Activity Codes to sort industries into 30 distinct sectors.

What’s the catch?

If your operation fits into any of these sectors, you’ve got to snag this permit for your stormwater discharges. Even secondary activities at your site might require coverage.

And it’s not just factories and mines—universities, military sites, and even some temporary construction gigs need to play by these rules.

Know your SIC codes and don’t sleep on getting your permit in order.

Key Permit Conditions and Requirements

So, you’ve got your permit. What’s next?

The MSGP has a laundry list of must-dos for your facility to prevent it from turning into an environmental villain.

  1. Blueprint Your SWP3: SWP3 is your game plan for keeping pollutants in check. Think of it as your playbook for Best Management Practices (BMPs).
  2. Quarterly Check-ups: Like clockwork, every three months, do a walkthrough. Check your stormwater controls and tick off those boxes.
  3. The Eyeball Test: Also quarterly, eyeball your stormwater discharges at each outfall. Visuals can be more telling than you think.
  4. Lab Coats On: Some sectors have to sample stormwater discharges. Bring in the test tubes and get sciency with pollutant indicators and numeric limits.
  5. Daily Drills: From spill prevention and housekeeping to employee training, make it routine. It’s like cleaning your room but on an industrial scale.
  6. The Special Stuff: Part V of the permit outlines some additional, sector-specific do’s and don’ts. Know it like the back of your hand.

And don’t forget the paperwork. File your Notice of Intent (NOI) or No Exposure Certification (NEC) to make it all official.

Done right, all these steps not only keep you compliant but make sure the water leaving your site is a whole lot cleaner.

The Stormwater Pollution Prevention Plan (SWP3)

A key requirement of the MSGP TXR050000 is developing and implementing a SWP3 for the industrial facility.

Before you even think about filing that NOI, get your SWP3 in order. This isn’t optional; it’s the cornerstone of your entire stormwater management strategy. Here’s what you absolutely need to cover:

  1. Lay of the Land: Sketch out your site. Describe the activities, the location, and all impervious surfaces that could contribute to runoff.
  2. Spotting the Culprits: Pinpoint the activities, materials, or site features that could be the bad guys in your pollution story.
  3. Your Defense Strategy: List out the structural and non-structural controls you’ll use to block pollutants from making an escape in stormwater.
  4. Your Game Plan: Establish timelines for all the nitty-gritty — good housekeeping, spill responses, maintenance routines, and training sessions.
  5. Crossing the T’s: Make sure you’re good on the legal side by documenting all the required environmental considerations.
  6. Seal It: Put your John Hancock on it. Certification is a must.
  7. The Map: You’ll also need a tactical map showing drainage areas, discharge points, sample spots, and where you’ve set up your defense (your structural controls).

Remember, SWP3 isn’t a set-and-forget deal.

Review it annually or whenever your site changes, and tweak the plan accordingly. It’s your roadmap to staying on the right side of the law, and more importantly, protecting the environment.

Quarterly Inspection: Your Four-Point Health Check

Four times a year, at a minimum, you’ll have to do a deep dive into your facility to make sure your SWP3 isn’t just a paper exercise. Here’s your checklist for what needs to get eyeballed:

  1. Target Zones: Hit all the hotspots—your storage sites for materials, maintenance yards, dust generators, loading docks, and anywhere you store or fix equipment.
  2. What to Look For: Pay close attention to signs of spills or leaks. Assess the condition of your control measures and look for evidence of pollutants in your drainage systems. Identify places where you can make your BMPs even better.
  3. Fix It Fast: Any issues you find? Get them corrected ASAP, generally within a two-week window.
  4. Paper Trail: Keep records detailing what you inspected, what you found, and any SWP3 changes you had to make as a result.

Don’t underestimate the importance of these quarterly checks. They’re not just about compliance; they’re also about constant improvement in your battle against pollution.

Quarterly Visual Monitoring: Your Eye on Stormwater Quality

For visual monitoring, think of it as quality control for your facility’s stormwater. Conduct these during daylight and normal work hours. You’re scrutinizing:

  1. Water Traits: Check color, odor, and turbidity. Note floating solids or any scum.
  2. Pollutants: Be alert for oil sheen or obvious contaminants.
  3. Effluent Guidelines: For sectors with federal numeric limits, assess clarity and solids.
  4. Benchmark Sampling: If your sector demands it, collect applicable samples.

Document your findings, corrective actions, and benchmark data. Store this diligently; it’s both your paper trail and your to-do list for SWP3 updates.

Remember, getting this right means moving smoothly through permitting and, more importantly, reducing environmental impact.

So, each quarterly visual is not just a check-box task but a cornerstone of effective stormwater management.
