San Antonio, Texas — SAN ANTONIO — Two home explosions, five people seriously injured, and hundreds of gas leak records are raising new questions about where leaks are happening across San Antonio and what state records say about how some underground gas lines were damaged.

Yami Virgin Investigates has spent months requesting government records following two major San Antonio-area explosions.

In April, two homes on Preston Hollow Drive exploded hours apart, seriously injuring five people.

Federal investigators confirmed the explosions were fueled by natural gas. The National Transportation Safety Board said it found a gas leak in a service line at the home between the two explosion sites.

Investigators are still investigating the cause of the leak and the explosions.

Less than a year earlier, a home at 7914 Laurel Bend exploded, leaving a man inside with severe burns.

CPS Energy later disclosed that it found a gas leak in a service line on the next-door property. The utility did not say that leak caused the explosion.

Following those incidents, FOX SA began requesting government records involving gas leaks.

Some records have been released. CPS Energy has asked the Texas Attorney General’s Office for permission to withhold other records requested by FOX SA.

Hundreds of Grade 1 leak records

Earlier this year, FOX SA obtained state data showing more than 1,000 gas leaks reported in Bexar County during a separate six-month reporting period.

Now, newly obtained records provide something FOX SA did not have before: individual street addresses.

The latest records FOX SA reviewed include 801 gas leak records from 2024 and 2025.

Of those, 680 were classified as Grade 1 — the highest-risk leak classification requiring immediate repair.

That is nearly 85%.

An analysis of the addresses also found some locations appearing more than once.

Three Grade 1 records at one address

At 2741 Woodbury Drive, the same address appears three times in the records within less than a month.

All three records were classified as Grade 1.

The first two were repaired two days apart and list “ground movement” as the cause.

The third lists “operator personnel/contractors excavating.”

The records alone do not establish whether the three entries represent three separate underlying problems, so FOX SA has asked CPS Energy for clarification.

Woodbury was not the only area where leak records appeared close together.

Three Grade 1 records on Big Horn Bend

On the 4000 block of Big Horn Bend, FOX SA found three addresses with Grade 1 leak records.

Two of them — 4011 and 4015 Big Horn Bend — are just four house numbers apart.

Both list the broad leak-cause category as “Other Third Party Excavators.”

FOX SA then compared those addresses with a separate set of Texas Railroad Commission records documenting pipeline damage incidents.

Those records provide information not in the leak reports, including the excavator’s name and a more specific listed damage cause.

For both 4011 and 4015 Big Horn Bend, the additional records identify JYV Communications as the excavator.

But the listed damage cause for both incidents is “Locator error.”

The records also include the language: “Line locator failed to use information to mark accurately.”

That distinction is important.

The leak report identifies third-party excavation as the broad category associated with the leak. The separate pipeline-damage record provides additional information about what state records say happened during the damage incident.

The records do not, by themselves, establish responsibility ultimately.

What the pipeline damage records show

FOX SA also analyzed the separate Railroad Commission pipeline-damage data.

The file contained multiple entries for some of the same incidents. After counting each incident only once, FOX SA identified 64 different pipeline-damage incidents.

Of those:

29 list “Locator error” as the damage cause.

15 list “Incorrect facility records/maps.”

Nine list “Facility marking or location not sufficient.”

Combined, 53 of the 64 incidents list a damage cause involving locating or marking underground lines, or the records used to locate them.

These 64 pipeline-damage incidents come from a separate Railroad Commission dataset and should not be interpreted as 64 of the 801 gas leak records.

FOX SA is asking the Railroad Commission to explain what those classifications mean, who is responsible for locating and marking underground lines in those cases, and what the records establish about responsibility.

CPS Energy responds

CPS Energy sent FOX SA a statement Sunday addressing what happens when third-party contractors damage its gas lines.

“When third-party contractors hit CPS Energy gas lines, CPS Energy enacts its damage prevention protocol, which includes safety outreach to contractors the same day,” the utility said. “CPS Energy tracks all contractors that hit CPS Energy lines and the damage that is caused to those lines.”

The statement does not explain what CPS Energy does with that information after tracking contractor and damage incidents.

FOX SA has asked CPS Energy what happens when Grade 1 leak records repeatedly appear at the same address, whether repeat records trigger additional inspection of surrounding infrastructure, and who is responsible for locating and marking CPS Energy gas lines before excavation begins.

FOX SA is also asking the Texas Railroad Commission for clarification about the damage records and what terms such as “locator error,” “incorrect facility records/maps” and “facility marking or location not sufficient” mean.

The records do not clearly establish who was ultimately responsible for each leak or pipeline-damage incident.

Yami Virgin Investigates will continue following the records and the agencies’ responses.
