SpaceX has responded to a critical report from CNBC alleging that it has repeatedly polluted waters in Texas this year. As per the private space company, the publication’s allegations about its launch operations in South Texas were factually inaccurate.
In its report, CNBC alleged that SpaceX violated environmental regulations by “repeatedly releasing pollutants into or near bodies of water in Texas.” The publication cited a notice of violation from the Texas Commission on Environmental Quality (TCEQ) about SpaceX’s water deluge system at Starbase, Texas, as part of its sources for its article.
The TCEQ reportedly received a complaint alleging that SpaceX “was discharging deluge water without TCEQ authorization” on August 2023. A total of 14 complaints alleging environmental impacts from Starbase’s deluge system have reportedly been received by the Harlingen region, the publication noted.

In its response, which was posted through its official account on X, SpaceX noted that it worked with the TCEQ when Starbase’s water deluge system was built. SpaceX also clarified that it has only used potable water in the operations of Starship’s water deluge system.
Following is SpaceX’s full response to CNBC’s allegations.
CNBC’s story on Starship’s launch operations in South Texas is factually inaccurate.
Starship’s water-cooled flame deflector system is critical equipment for SpaceX’s launch operations. It ensures flight safety and protects the launch site and surrounding area.
Also known as the deluge system, it applies clean, potable (drinking) water to the engine exhaust during static fire tests and launches to absorb the heat and vibration from the rocket engines firing. Similar equipment has long been used at launch sites across the United States – such as Kennedy Space Center and Cape Canaveral Space Force Stations in Florida, and Vandenberg Space Force Base in California – and across the globe.

SpaceX worked with the Texas Commission of Environmental Quality (TCEQ) throughout the build and test of the water deluge system at Starbase to identify a permit approach. TCEQ personnel were onsite at Starbase to observe the initial tests of the system in July 2023, and TCEQ’s website shows that SpaceX is covered by the Texas Multi-Sector General Permit.
When the EPA issued their Administrative Order in March 2024, it was done without an understanding of basic facts of the deluge system’s operation or acknowledgement that we were operating under the Texas Multi-Sector General Permit.
After we explained our operation to the EPA, they revised their position and allowed us to continue operating, but required us to obtain an Individual Permit from TCEQ, which will also allow us to expand deluge operations to the second pad. We’ve been diligently working on the permit with TCEQ, which was submitted on July 1st, 2024. TCEQ is expected to issue the draft Individual Permit and Agreed Compliance Order this week.
Throughout our ongoing coordination with both TCEQ and the EPA, we have explicitly asked if operation of the deluge system needed to stop and we were informed that operations could continue.
TCEQ and the EPA have allowed continued operations because the deluge system has always complied with common conditions set by an Individual Permit, and causes no harm to the environment.
Specifically:
– We only use potable (drinking) water in the system’s operation. At no time during the operation of the deluge system is the potable water used in an industrial process, nor is the water exposed to industrial processes before or during operation of the system.
– The launch pad area is power-washed prior to activating the deluge system, with the power-washed water collected and hauled off.
– The vast majority of the water used in each operation is vaporized by the rocket’s engines.
– We send samples of the soil, air, and water around the pad to an independent, accredited laboratory after every use of the deluge system, which have consistently shown negligible traces of any contaminants. Importantly, while CNBC’s story claims there are “very large exceedances of the mercury” as part of the wastewater discharged at the site, all samples to-date have in fact shown either no detectable levels of mercury whatsoever or found in very few cases levels significantly below the limit the EPA maintains for drinking water.
– Retention ponds capture excess water and are specially lined to prevent any mixing with local groundwater. Any water captured in these ponds, including water from rainfall events, is pumped out and hauled off.
– Finally, some water does leave the area of the pad, mostly from water released prior to ignition and after engine shutdown or launch. To give you an idea of how much: a single use of the deluge system results in potable water equivalent to a rainfall of 0.004 inches across the area outside the pad which currently averages around 27 inches of rain per year.
With Starship, we’re revolutionizing humanity’s ability to access space with a fully reusable rocket that plays an integral role in multiple national priorities, including returning humans to the surface of the Moon. SpaceX and its thousands of employees work tirelessly to ensure the United States remains the world’s leader in space, and we remain committed to working with our local and federal partners to be good stewards of the environment.

Although the two vehicles are built for completely different use cases, Tesla utilized engineering expertise while developing both the Cybercab and Semi to build a thermal architecture that would fit both vehicles. Of course, with some slight revisions.
The development was noted by Lars Moravy and Dan Priestley last week at Tesla’s Semi Handover event in Sparks, Nevada, where the company showed off its dedicated production facility for the Class 8 truck.
🚨 Tesla designed the integrated thermal systems for Cybercab and Semi at the same time as the vehicles were both in development
Tesla wanted to build one thermal system that worked with both vehicles, apart from small modifications.

Tesla’s decision to develop one thermal architecture for both the Cybercab and Semi is one of the more revealing engineering choices in the company’s 2026 lineup:
“We designed it at the same time we designed the Cybercab and we said okay we’re going to take our most efficient vehicle and our biggest vehicle and we’re going to take one thermal system and make it work for both.”
Core parts, meaning the compressor, pumps, and heat exchangers, are shared, with only modest changes to cooling-loop sizing and a larger radiator on the truck. The result, they said, is a compressor and thermal stack already proven across millions of miles, delivering “reliability from day one.”
Priestley also highlighted a practical payoff of the indirect design:
“There’s no AC lines, there’s no refrigerant lines…It comes from the factory fully charged, sealed with refrigerant, and it just exchanges coolant. It doesn’t actually run refrigerant up to the front of the vehicle.”
This eliminates potentially leak-prone plumbing that would otherwise require hands-on service, reducing overall uptime and potentially cutting into business margins. The megamanifold runs cabin HVAC and every powertrain heating and cooling loop at once, recapturing waste heat from motors and the battery instead of dumping it the way a diesel engine does.
The approach is just the latest chapter in a continuing story of stretching thermal solutions across wildly different vehicles. Model Y’s Octovalve evolved into the Super Manifold used on Cybertruck, and later Model S/X refreshes. Cybercab then introduced Supermanifold V3, which Tesla says is 80 percent automated to build and 38 percent more efficient than typical automotive thermal systems.
This thermal system is also shared with Cybercab – one thermal system for both our most efficient vehicle & our biggest vehicle

Tesla has done the same with the 4680 cells, both being utilized in the Cybertruck and Semi, and with heat-pump compressors that Priestley noted were already common across the passenger-car fleet.
Concurrent development of crucial vehicle elements buys scale and reliability that a truck-only thermal system could not match. High-volume passenger car parts are cheaper and more accessible, which can give fleets a sealed, low-maintenance loop of operation from their first day of operation.
For owners and operators, that translates into less energy spent on cabin heat in the colder months, fewer refrigerant-related repairs, and a thermal architecture already stress-tested at passenger-car volumes before the first high-volume Semi left the lines in Nevada.
Tesla CEO Elon Musk certainly tipped off some details of the Tesla Roadster event with a broadening of information regarding the company’s decision to delay the unveiling for two weeks.
For years, people have speculated about what the Roadster will be capable of. While there have been plenty of things said about what it *could* do, we have not seen or been told by Tesla what it will actually be capable of.
However, over the past few days, Tesla’s weather updates have truly pushed the speculation into Plaid Mode, basically all but confirming the car will have some sort of aerial capability — whether that would be hovering or fully flying remains to be seen — but it definitely seems that it will be able to leave the ground intentionally.
“Because this event can only be held outdoors…”
Tesla posted on Monday that it would delay the Roadster event until October 15, and it indicated that it had to do this because the event “can only be held outdoors.”
With the potential SpaceX collaboration to develop cold-gas thrusters that will help the vehicle go airborne, doing this indoors is probably not a safe, or even plausible, possibility.
Roadster event update
We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule.
New date is October 15. Additional details to…

FAA Airspace Restriction
The FAA gave Tesla a Temporary Flight Restriction (TFR) for 10,000 feet above ground level, much higher than the typical 2,000-foot restrictions that are usually placed at SpaceX’s McGregor, Texas site.
Tesla Roadster event requires restricted airspace, and the FAA obliges
Some have said that this massive increase is due to Tesla’s need to restrict unauthorized drone use for spying on the event.
Elon Admits High Winds
“Due to high winds, the new Roadster demo is postponed by 2 weeks,” Musk said in a post on X yesterday.

A reply reading, “What’s strong wind got to do with a car demo with four grounded wheels?” was directly below Musk’s post, satirically and sarcastically probing for more details.
All signs are pointing toward an aerial demonstration for the Roadster.
Tesla has secured $30 billion in fresh credit lines from Citibank and Wells Fargo in an effort to scale its biggest current projects.
Tesla agreed to a $20 billion three-year delayed-draw term loan facility from Citibank, it announced on Tuesday. Additionally, it signed a five-year, $8 billion revolving credit facility and a $2 billion, 364-day term credit facility with Wells Fargo.
In a filing with the Securities and Exchange Commission (SEC), that it “may draw” from the $20 billion delayed-draw term “from time to time” and “no more than ten times during the 18 months following the closing date.” This loan matures on September 29, 2029.
The five-year revolving facility from Wells Fargo will also be accessed by Tesla “from time to time,” and will become due and payable on September 29, 2031. Tesla can request two separate one-year extensions.
On the $2 billion, 364-day revolving loan, it becomes due and payable on September 28, 2027. Tesla can also increase its additional commitments to an additional $4 billion across the Revolving Facilities. This would increase the total facilities to $14 billion. Tesla said it does not plan to utilize any of these loans in 2026.
Tesla plans to utilize the money to help prop up its ambitions to scale its biggest products, each of which is either in early launch phases or still in development. Of course, we’re talking about Cybercab and Semi, which have launched, and Optimus, which is still under heavy development and working toward initial release.
All three Tesla products have one thing in common: they’ve all required Tesla to build new manufacturing lines for them.
For the Semi, Tesla built a brand new factory in Sparks, Nevada, adjacent to the Tesla Gigafactory. For Optimus, Tesla sunset Model S and X production at the Fremont Factory, which brought an end to the two flagship models, thus creating manufacturing space for the humanoid robot. Finally, Cybercab is being built at Gigafactory Texas and officially entered production earlier this year.
The cash will help Tesla bolster its finances for the continuing development of these products. Tesla said that it forecasts its CapEx to be over $25 billion, up from just over $8.5 billion last year. These loans surely help with that spending.
