You’ve probably seen the signs or heard the chatter if you spend any time on the Northeast Side of San Antonio. It’s a lot of noise. Literally and figuratively. The Vulcan Gomez asphalt plant isn't just a piece of industrial machinery; it’s basically become a landmark for local debate over land use, industrial growth, and how a city balances its need for smooth roads with the sanity of the people living next to them.
People want good roads. We hate potholes. But nobody ever wakes up and thinks, "Gee, I'd love a high-capacity hot-mix asphalt facility right in my backyard." That’s the tension. Vulcan Materials Company, a massive player in the construction aggregates world, operates the Gomez facility at 11601 Starcrest Drive. It’s strategically located, sitting right near the Wurzbach Parkway and the airport. From a logistics standpoint? It’s a goldmine. From a residential standpoint? It’s... complicated.
Understanding the Vulcan Gomez Footprint
Let’s get the basics down. This isn't some small-time operation. Vulcan Materials is a Fortune 500 company. They know what they’re doing. The Gomez plant is a key cog in their Central Texas operations. It’s designed to produce hot-mix asphalt (HMA), which is the stuff that gets trucked out at 300 degrees Fahrenheit to pave everything from I-35 to your local grocery store parking lot.
The plant uses a mix of crushed stone, sand, and liquid asphalt cement. These materials are heated and blended in a massive drum. If you’ve ever driven past and seen that giant rotating cylinder—that’s where the magic (and the smell) happens. Honestly, the smell is what people usually complain about first. It’s that heavy, oily, "new road" scent that sticks to the back of your throat. While the industry says it’s mostly steam and harmless particulates, the folks in the nearby neighborhoods often beg to differ.
Industrial sites like this are heavily regulated, or at least they’re supposed to be. In Texas, that means the Texas Commission on Environmental Quality (TCEQ) holds the reins. The Vulcan Gomez plant operates under specific air quality permits that dictate how much dust and organic compounds they can release.
The Logistics of Asphalt in a Growing City
Why here? Why San Antonio?
Simple. San Antonio is exploding. You’ve seen the cranes. You’ve seen the endless suburban sprawl heading north toward New Braunfels. All that growth requires pavement. Asphalt has a "shelf life" when it’s hot. You can’t mix it in Austin and drive it to south San Antonio; it’ll cool down and become unworkable. You need plants close to the job sites.

The Gomez plant is positioned to serve the heart of the city. If that plant shut down tomorrow, the cost of road repairs in the immediate area would likely spike because contractors would have to haul material from further away. That’s the business reality that often gets lost in the emotional heat of public meetings.
Vulcan’s presence in the region is massive. They don’t just do asphalt; they own quarries. This vertical integration is why they dominate. They mine the rock, they crush the rock, they mix it with oil, and they sell it to the paving crews. It’s an efficient machine. But that efficiency comes with a footprint that includes heavy truck traffic—dozens, sometimes hundreds of trucks a day—rumbling in and out of the Starcrest area.
Environmental Concerns and TCEQ Oversight
Let’s talk about the elephant in the room: the air.
If you look at the TCEQ records for "Vulcan Construction Materials LLC" at the Gomez site, you’ll find a history of permits and renewals. These documents are dry. They’re filled with technical jargon about "particulate matter" and "volatile organic compounds" (VOCs). Basically, the plant uses baghouses—think of them as giant vacuum cleaner bags—to catch the dust before it leaves the stack.
But things go wrong.
Equipment malfunctions. Wind shifts. Sometimes, the "blue smoke" (which is actually tiny droplets of liquid asphalt) escapes. Residents in the surrounding area have, over the years, raised concerns about silica dust and its long-term health effects. Silica is no joke; it’s a known respiratory hazard. Vulcan maintains that their filtration systems meet or exceed state standards.

Kinda makes you wonder who’s actually checking, right? The TCEQ is often criticized for being "industry-friendly." This has led to a lot of grassroots organizing in San Antonio. Groups like the Greater Edwards Aquifer Alliance and various neighborhood associations keep a hawk-eye on these plants. They aren't just worried about the air; they’re worried about the water. While the Gomez plant isn’t sitting directly on the most sensitive part of the Recharge Zone like some of Vulcan’s other proposed sites (like the one in Comal County), any industrial site with heavy chemical usage carries a risk of runoff.
The Reality of Living Near a Hot-Mix Plant
It’s not just the health stuff. It’s the quality of life.
Imagine it’s 5:00 AM. You’re trying to sleep. A fleet of diesel trucks starts idling. The "beep-beep-beep" of backup alarms becomes your alarm clock. That’s the reality for some neighbors.
Then there’s the light pollution. These plants often run late into the night or start incredibly early to get ahead of the Texas heat and the traffic. The glow from the facility can be intense. Vulcan has made efforts in some locations to install directional lighting and sound baffles, but you can only do so much to hide a massive industrial operation.
Property values are another sticking point. It’s a weird market. On one hand, the Northeast Side has seen some great appreciation. On the other hand, being "the house next to the asphalt plant" is a tough sell for a young family. It creates a ceiling on how much those homes can truly worth.
What Most People Get Wrong About Vulcan Gomez
One big misconception is that the plant is "illegal" or operating in the shadows. It’s not. It’s fully permitted.

Another mistake? Thinking they only make asphalt. These sites often serve as recycling centers too. They’ll take old, torn-up roads (Reclaimed Asphalt Pavement, or RAP), crush it down, and mix it back into the new stuff. It’s actually pretty sustainable in a weird way. It keeps mountains of old road out of landfills.
But sustainability doesn't mean it’s silent.
People also tend to blame Vulcan for every crack in the nearby roads. While their trucks certainly contribute to wear and tear, the geology of San Antonio—with its shifting clay soils—is the real villain there. The plant is just an easy target because it’s big and loud.
The Bigger Picture: Industrial vs. Residential
The saga of the Vulcan Gomez asphalt plant is really a story about San Antonio’s lack of strict zoning in certain areas. Historically, this part of the city was "the outskirts." It made sense to put a plant there in the 70s or 80s. But then the city grew around it.
Now you have this awkward situation where industrial zones are rubbing shoulders with schools and parks. It’s a friction point that isn't going away. Vulcan isn’t going to walk away from a multi-million dollar asset easily, and the residents aren't going to stop wanting clean air.
In recent years, we’ve seen more "contested case hearings" across Texas regarding these types of facilities. This is where the public gets a chance to challenge a permit before a judge. While it’s an uphill battle for citizens—Vulcan has better lawyers, obviously—it has forced companies to be more transparent about their emissions data and operational hours.
Actionable Steps for Concerned Residents or Business Owners
If you live near the Vulcan Gomez plant or are considering moving to the area, you shouldn't just take things at face value.
- Check the TCEQ Central Registry: You can search for "Vulcan Construction Materials" and find the specific compliance history for the Gomez site. Look for "Notice of Violations" (NOVs).
- Monitor the Air: Don't rely solely on the plant's sensors. Low-cost monitors like PurpleAir can give you real-time data on particulate matter (PM2.5) in your specific neighborhood.
- Document Everything: If there’s an unusual smell or a massive plume of dust, take photos and videos with time stamps. Report it to the TCEQ Region 13 office immediately.
- Join the Neighborhood Association: Strength is in numbers. Individual complaints are often ignored; a formal letter from a homeowners association (HOA) with 500 signatures carries weight at City Hall.
- Understand the "Standard Permit": Most of these plants operate under a "Standard Permit for Hot Mix Asphalt Plants." Read it. Know what they are allowed to do. If they are running outside their permitted hours or without their dust suppression systems on, they are in breach.
The Vulcan Gomez asphalt plant is a necessary evil in the eyes of city planners and a constant nuisance in the eyes of its neighbors. It represents the gritty reality of how a modern city functions. You can’t have the smooth ride on the highway without the smoke and the noise of the plant that built it. The goal isn't necessarily to shut it down—that’s probably not happening—but to hold the operators to the highest possible standard of corporate citizenship.
