Opinion by Judge Foley

Judges May and Altice concur.

Foley, Judge.

[1] Carla Miller (“Miller”) appeals from the trial court’s order granting summary judgment in favor of Indiana Gas Company, Inc. (“Indiana Gas”). Miller raises the following restated issues for our review:

I. Whether the trial court abused its discretion when it relied on certain evidence designated by Indiana Gas because the evidence was inadmissible;

II. Whether the trial court erred in granting summary judgment in favor of Indiana Gas because genuine issues of material fact existed.

[2] We affirm.

Facts and Procedural History 1 [3] On May 19, 2019, at approximately 4:56 a.m., a natural gas explosion occurred

at 904 Assembly Road, Jeffersonville, Indiana—the residence of Billy and Janet Phillips (“the Phillips Residence”). Janet Phillips (“Janet”) awoke in the early morning hours to get ready for work, and when she flipped on a light switch in her basement, the spark caused an explosion. Billy Phillips (“Billy”) was killed in the explosion, and the Phillips Residence was destroyed. Janet suffered grave personal injuries, and Miller, who lived next door to the Phillips

1 Oral argument was heard on this case on January 27, 2025, in the Indiana Court of Appeals courtroom in Indianapolis, Indiana. We commend counsel on the excellent quality of their written and oral advocacy.

Residence, also suffered personal injuries and property damage as a result of the explosion (“the Incident”).

[4] Indiana Gas is a public utility that provides natural gas service to retail customers through its pipelines subject to regulation by the Indiana Utility Regulatory Commission (“IURC”) and the federal Pipeline and Hazardous Materials Safety Administration (“PHMSA”). At the time of the Incident, Indiana Gas provided natural gas service to the Phillips Residence pursuant to the terms and conditions of the Tariff for Gas Service approved by the IURC (“the Tariff”). The Tariff states: “It shall not be the duty of [Indiana Gas] to inspect [the] Customer’s piping, appliances or equipment.” Appellant’s App. Vol. VII p. 90. It also states: “[Indiana Gas] shall not be liable for damages caused by defective piping or appliances on [the] Customer’s Premises.” Id. at 96. Further, “[The] Customer shall furnish, install, and maintain all necessary piping beyond the outlet side of the [gas] meter. . . .” Id. at 90. The natural gas industry uses the concept of jurisdiction when addressing whether a natural gas incident involved pipelines owned by the utility—and thereby under the regulatory jurisdiction of the IURC and PHMSA—or gas lines owned by the customer, which would be outside of that jurisdiction. If the cause of a natural gas incident is deemed to be “not jurisdictional” or “non-jurisdictional,” this means the source of the natural gas involved in the incident was not a leak from gas lines the utility owned or was responsible for. Id. at 18.

[5] Natural gas is colorless, odorless, and highly flammable and explosive when mixed with air. Because of this, federal regulation 49 C.F.R. § 192.625(a) states that “a combustible gas in a distribution line must contain a natural odorant or be odorized so that at a concentration in air of one-fifth of the lower explosive limit, the gas is readily detectable by a person with a normal sense of smell.” The lower explosive limit (“LEL”) of natural gas in air is approximately 5%, and therefore, the regulation requires that odorant in natural gas be “readily detectable by a person with a normal sense of smell” at no more than 1% gas in air. Appellant’s App. Vol. VII pp. 147, 152.

[6] After the Incident, individuals from Indiana Gas and the IURC arrived at the scene to investigate. Indiana Gas performed its investigation under the observation of Dan Novak (“Novak”) and Howard Friend (“Friend”) from the IURC. Indiana Gas conducted a gas leak survey including bar hole testing, which consists of making a hole in the soil and testing for the presence of natural gas using a combustible gas indicator; walking along the gas main to check cleanouts and sewer manholes using a flame ionization unit to detect the existence of natural gas; and pressure testing the service line. The gas leak survey and pressure tests conducted on the service line into the Phillips Residence were both negative for leaks within the jurisdiction of Indiana Gas’s facilities. Indiana Gas, accompanied by the Jeffersonville Fire Department, performed odorator readings at three locations near the Phillips Residence on the day of the explosion. An odorator is an instrument used to determine the percentage of gas in air at which the odor becomes readily detectable. The odorator readings were: 0.21% (next door to the north of the Phillips Residence); 0.21% (next door to the south of the Phillips Residence); and 0.28%

(across the street from the Phillips Residence). All three readings were well within the regulatory standard of no more than 1% gas in air.

[7] Indiana Gas’s investigation revealed that the source of the natural gas was a section of gas pipeline inside the Phillips Residence basement that was uncapped and no longer connected to a fitting. The investigation determined that “[t]he cap had been removed from the open line by human intervention” and that “[t]o remove the pipe cap would require two wrenches, one to hold the pipe nipple and one to remove the cap.” Appellant’s App. Vol. VIII p. 9.

[8] The explosion triggered an excess flow valve installed underground on the service line to close, which immediately cut off all gas flow to the Phillips Residence. The excess flow valve functioned as it was designed to do. The gas meter at the Phillips Residence had an Encoder Receiver Transmitter (“ERT”) that stored a rolling forty days’ worth of readings. The ERT data collected from the gas meter showed a sudden increase in gas flow that started between 3:00 p.m. and 4:00 p.m. on May 18, 2019—the day before the explosion. After 4:00 p.m. on May 18, gas continued flowing at a high rate until the explosion, which indicated natural gas flowed at a high rate into the Phillips Residence for approximately thirteen hours before the explosion.

[9] No Indiana Gas personnel were at the Phillips Residence on May 18, 2019, which was a Saturday. The only individuals present at the Phillips Residence on May 18 were Billy and Janet Phillips. On May 18, both Billy and Janet worked in the yard from around 8:00 or 9:00 a.m. until 3:00 or 4:00 p.m. When

Janet finished, she left to go to the grocery store and get gas for her car while Billy remained alone at the residence. Billy was the only individual at the Phillips Residence during the approximate time when the ERT data showed the sudden increase in gas flow began. There was evidence that Billy completed plumbing, electrical, painting, drywall, and flooring projects and kept tools at the Phillips Residence.
