The following is supplemental documentation designed to highlight some of our reporting on the fatal 2018 natural gas explosion in Dallas.

Since 2006, WFAA has investigated Atmos Energy’s failure to pull faulty and corroding gas pipes out of the ground. After the death of 12-year-old Linda “Michellita” Rogers, WFAA ramped up our efforts to get answers.

After the deadly explosion, WFAA began pressing Atmos for a map of the types of pipe it had in the ground in North Texas. How much was faulty cast-iron pipe? This is information that Atmos had long tried to keep from the public, claiming it was a security issue. We discovered that Dallas County Judge Clay Jenkins had a copy, and through an open records request, he released it to us.

We have included the initial, rudimentary map we received, as well as a letter and chart summarizing Atmos’ repair schedule (note the timing of spikes in Atmos’ replacement of cast iron pipes, around the time when WFAA’s coverage ramped up in 2006 and 2011). This was the first sense the public had about the makeup of the gas pipeline system underneath the ground in Dallas. We’ve also included a more detailed map Atmos later released, under pressure from us and local leaders.

Within hours of the explosion that killed Michellita, WFAA also began filing open records requests with the Texas Railroad Commission, which despite its name regulates gas pipelines in the state.

Those requests paid off. An early question in the investigation was, did Atmos try to evacuate Michellita’s neighborhood after two nearby houses were damaged by gas leak fires days before she was killed? We found this email, sent hours before Michellita’s house blew up, in which an Atmos executive downplays the risks from the first two gas leak fires. She told the Railroad Commission that crews were “continuing to monitor the surrounding area” that added that “there have been no evacuations or road closures.”

After Michellita’s death, the federal National Transportation Safety Board, which took over the investigation, found that Atmos had knowledge of leaks in that immediate area at least two months before the deadly explosion, according to a preliminary report.

WFAA found that this wasn’t the first time Atmos failed to evacuate homes near a serious gas leak.

We were the first to report on a 2017 house explosion in nearby Irving, Tx. On New Year’s Eve night, Atmos crews were alerted to a gas leak and began working on repairs. A resident who lived next to the site repeatedly asked an Atmos supervisor if she should leave.

“The Atmos representative stated there was not a need to evacuate,” according to an Irving Fire Department memo WFAA obtained. Hours later, the house exploded, sending multiple family members to the hospital. Thankfully, no one died.

How much in fines had the state regulator, the Texas Railroad Commission, assess Atmos for its poor gas line maintenance? As WFAA discovered, there was no easy way to find out. WFAA producer Mark Smith dug into the arcane and hard-to-navigate state civil administrative dockets looking for penalties levied against Atmos, and found scant evidence of accountability. Here’s an example of the Railroad Commission finding “Atmos failed to protect people” by letting gas leak from its system. The multibillion-dollar utility’s punishment? A $25,000 fine. WFAA determined that Atmos paid about $194,000 in fines over the past five years – a pittance compared to its revenues, experts told us.

We wanted to know why the Texas Railroad Commission had not held Atmos more accountable over the years. The Commission is led by three elected commissioners, including Ryan Sitton. During a visit to Dallas, he refused to criticize Atmos’ failure to evacuate residents. WFAA scoured campaign finance records and found that Atmos’ political action committee gave Sitton’s campaign $10,000 and $15,000.

We explored the phenomenon of “odor fade,” in which chemicals Atmos is supposed to add to its natural gas dissipate. Previously, Atmos called odor fade a “theory,” but the manufacturer’s own safety sheet for the odorant warns “odor intensity may fade or be eliminated for a variety of chemical and physical causes…”

So, how bad are leaks across Atmos’ Texas system? WFAA decided to find out. We embarked on exhaustive analysis of reams of gas leak data and made shocking discoveries. We’ve included some of our findings, including that Atmos let $98 million in gas leak since 2010.

Our analysis also showed that Atmos often waits weeks, if not months, to fix even the most serious leaks. We’ve included the Texas law that mandates Grade 1 leaks be repaired “immediately.” Our analysis found that Atmos took 142 days to fix one Grade 1 leak. We have also included a screenshot of one of our many interactive maps we built for our digital audience.

Honorable Clay Jenkins, Dallas County Judge 411 Elm Strnet Dallas, Texas 75202

Dear Judge Jenkins:

Jeffrey S. Knights, PE Vice President, Technical Services

Mid-Tex Division

On Febrnary 11, 2015, Atmos Energy provided you an update regarding the ongoing pipe replacement

programs in Texas, specifically the status of the cast iron pipe replacement activity in Dallas County. As

you have requested, I would like to provide you with all update Oil this activity.

Atmos Energy continues its comprehensive pipe replacement program that prioritizes segments based on

various factors, notjust pipe material. This program is based on the company's Distribution Integrity

Management plan developed in compliance with state and federal regulatory entities. This replacement

activity includes all pipe types including steel, plastic, and cast iron on both mains and service Jines.

By partnering with om· state regulatory agencies and local governments, we continue to make significant

improvements to our infrastructure. Atmos Energy has invested over one billion dollars in OUJ' Mid-Tex

system over the last five years. About 70% of that investment has been dedicated to increasing safety nnd

reliabiUty.

With respect to the replacement of cast iron type pipe in Dallas County, I am pleased to advise you that our

efforts are continuing at an accellerated pace within Dallas County, Atmos Energy has recently increased

it's conh·actor crews by 25-30% with over 30 crews now dedicated to cast iron pipe replacement in Dallas

County. At this increased level, Atmos Energy remains on target to be cast iron free by the end of calendar

year 2023.

We have reduced the known cast iron by au additional 48 miles since the last communication in February.

Atmos continues to collaborate and communicate with the cities of Dallas, Highland Park, and University

Park on the timing to complete this replacement activity in each of these cities. This partnership is

resulting in minimal disturbances to your residents and excellent relationship with these cities.

The current inventory of cast iron in your Dallas County cities is as follows: ~ YearEnd2014 JuneEnd2017 Cockrell Hill l.2 miles cast iron free Highland Park 10.2 miles 4.6 miles University Park 30.4 miles 24.9 miles Dallas 457.4 miles 408.9 miles

These programs continue to support our ongoing mission to operate the safest and most reliable natural gas

delivery systems in the nation. Atmos Energy enjoys our relationship with Dallas County and wants to

continue our partnership. We appreciate your continued support of our efforts. 1 will update you on our

progess preiodically, but please feel free to contact me or Susan Harris if you have any questions.

Sincerely,

M4~ Jeffrey S. Knights

Atmos Energy has been monitoring a situation in a residential area of Dallas near Love Field airport (airport not impacted).  We have responded to two separate leak investigations where fires within those homes had occurred.  Based on the information we have at this time we believe measured gas was potentially a factor in both.  As an enhanced safety measure, Atmos crews are continuing to monitor the surrounding area for potential leaks and will make repairs as needed.  Media has inquired about the situation so we wanted to make your team aware that our crews are currently onsite.  There have been no evacuations or road closures.  We will provide more information as it becomes available.  Please let me know if you have any questions.  Thank you,  Marlo A Sutton, P.E. | Dir Regulatory&Compliance | Atmos Energy Corporation | Mid-Tex Division | 214-206-2033 Office | 214-957-3295 Cell | Marlo.Sutton@atmosenergy.com | www.atmosenergy.com

PRELIMINARY REPORT PIPELINE

Natural Gas-Fueled Explosion of Residence

Dallas, Texas

February 23, 2018 PLD18FR002

The information in this report is preliminary and will be either supplemented or corrected during the course of the investigation.

On February 23, 2018, about 6:38 a.m. central standard time, a natural gas-fueled explosion

occurred at a newly renovated single-story residence at 3534 Espanola Drive in Dallas, Texas. The Dallas Fire-Rescue Department (DFRD) quickly dispatched units to the scene. The DFRD reported significant structural damage to the house; however, neither smoke nor fire was present.

Due to the nature and the number of leaks discovered in this residential neighborhood,

more than 300 residences evacuated. This evacuation was in place until February 24, 2018. Figure 1 shows the post-explosion view of the residence at 3534 Espanola Drive.

Figure 1. Post-explosion view of the residence at 3534 Espanola Drive.

When the explosion occurred at 3534 Espanola Drive, a family of five was asleep in the residence. Four family members were injured, and a 12-year-old juvenile was killed. The family was transported to a local hospital.

The injured residents told the DFRD arson investigators that the night before the explosion, they had heard “popping” noises, but they were unable to discover the source. They had not smelled any natural gas prior to the explosion.1

In the 48 hours prior to the accident at 3534 Espanola Drive, work crews from Atmos

Energy (Atmos) were in the neighborhood to investigate gas-related fires at two residences on Durango Drive. Figure 2 shows the location of the steel 2-inch-diameter pipeline and the three residences.

Figure 2. This highlighted grid shows the location of three destroyed residences: yellow

indicates the residence destroyed by an explosion on February 23, 2018; green indicates the two residences destroyed by fire on February 21-22, 2018. (Photo provided by Atmos Energy.)

On February 21, 2018, about 5:49 a.m., an explosion and subsequent fire occurred at 3527

Durango Drive. (This site is about 415 feet from the Espanola Drive house explosion.) The resident told arson investigators from the DFRD that about 2:00 a.m. he awoke to a “popping” noise from his heating, ventilation, and air conditioning (HVAC) unit. When he went to the attic, he saw the cover plate for his HVAC unit was on the floor; the loose cover plate was not mounted on the unit as usual. He also noticed that the pilot light on the HVAC unit was not working. When he placed the cover plate on his HVAC unit, an explosion occurred. He was thrown several feet; he received second degree burns. Figure 3 shows the post-explosion view of the residence at 3527 Durango Drive.

1 Natural gas is an odorless, combustible gas; however, Title 49 Code of Federal Regulation 192.625(a),

states, “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.” Properly odorized natural gas may be stripped of its odorant, if the gas travels through soil.

On February 22, 2018, about 10:21 a.m., a structural fire occurred at 3515 Durango Drive. (This location is less than 310 feet from the Espanola Drive house explosion.) The resident told DFRD arson investigators that while he was boiling water on the stove in his kitchen, the flames from the stove were “red and out of control.” The resident had second degree burns to his right arm and right leg. As the fire moved from the stove to the attic, it caused significant fire and smoke damage. As a result, the residence was a total loss. Figure 4 shows a post-fire view of the residence.

Prior to the explosion at 3534 Espanola Drive, the DFRD arson investigators had classified both incidents on Durango Drive as an “undetermined” cause. However, based on the nature of these two incidents, the NTSB is investigating whether these three incidents are related.

Due to the two incidents on Durango Drive, Atmos assessed the neighborhood. Atmos identified multiple leaks at various leak grade levels.2 Atmos started repairs on February 22. A review of odor reports and the activity by Atmos in the neighborhood shows that leaks were first detected on January 1, 2018. Atmos had performed various repair work prior to and during the days these three incidents occurred.

Numerous other leaks have since been identified throughout the neighborhood. On

February 23, 2018, after the explosion on Espanola Drive, Atmos shutdown the natural gas main pipeline between Espanola Drive and Durango Drive. On March 1, 2018, Atmos shut down its natural gas distribution system for 3-plus weeks. This shutdown impacted about 2,800 residences. These residents were not required to evacuate.

On scene, the NTSB formed the following three technical investigative working groups:

• Pipeline Operations and Pipeline Integrity Management • Human Performance and Safety Management Systems • Emergency Response/Hazardous Materials

During the investigation, the NTSB investigators: (1) inspected the incident sites, (2) pressure-tested the pipe, (3) collected records of the pipeline operations, the pipeline integrity management program, and the emergency response, and (4) interviewed personnel from Atmos and the DFRD.

While on scene, the NTSB investigators identified three sections of the pipe that failed a pressure test. One section was behind the residence at 3534 Espanola Drive; it had a circumferential crack. Sections of the pipe that failed the pressure test were shipped to the NTSB metallurgical laboratory in Washington, DC. Figure 5 shows the circumferential crack on the pipeline.

2 Leaks are graded by class. A Grade 1 leak represents an existing or probable hazard to persons or property

and requires immediate repair or continuous action until the conditions are no longer hazardous. A Grade 2 leak is recognized as being non-hazardous at the time of detection, but justifies scheduled repair based on probable future hazard. A Grade 3 leak is non-hazardous at the time of detection and can be reasonably expected to remain non-hazardous.

During the process of this examination, I contacted or interviewed the following witnesses:

Occupant 1 - Magdalena Tijerina Lopez (Spanish speaking) interviewed with assistance from eldest daughter

– Densy Armas. Densy Armas was not involved in the fire incident and not an occupant of the home.

Occupant 2 - Juan Manuel De La Cruz (Spanish speaking) interviewed with assistance from son in law –

Julian Armas. Julian Armas was not involved in the fire incident and not an occupant of the home.

Occupant 3 - Alejandra De La Cruz interviewed. Involved in fire incident sleeping in second story of home,

awaken by explosion. Initially trapped by fire on second floor, Alejandra De La Cruz managed to evacuate

home with son Adrian Guerra and holiday guest Jose Luis De La Cruz.

I gathered the following information while interviewing the family: The family went out to eat dinner on

Sunday, December 31, 2017, and returned home approximately 23:30. An Atmos representative knocked on

the front door of the home addressed 3567 Colgate Lane to gain permission to access the front lawn to search

for a gas leak. Permission was granted to Atmos and occupant Magdalena Lopez was concerned; she asked

the Atmos representative if there was a need to evacuate the home. The Atmos representative stated there was

not a need to evacuate the home, the Atmos representative continued saying the repairs were outside of the

home and in the street. During the interview of Magdalena Lopez, she expressed to me that she asked the

Atmos crews on scene approximately three times if it was safe to remain in the home or should they leave

during the repairs.

The occupants were asked to describe their experiences. The following is a summary of the information

obtained as a result of a voluntary interview(s):

Occupants sleeping on the second floor of the home observed fire on the second floor of the home. Second

floor occupants found themselves trapped by fire; second floor occupant Alejandra De La Cruz gathered

clothes and threw those clothes on the fire. The fire smothered for a moment allowing the second floor

occupants time to retrieve her son and evacuate the home. Second floor occupants met with the other

occupants of the home in the front lawn north side of the home on Colgate Lane. Occupant Magadalena

Tijerina Lopez sleeping in the Living room on the first floor of the home explained: while sleeping on the

sofa burning debris fell on her. She pushed the burning debris off and evacuated the home with one pet and

keys to the family vehicle. Occupant Juan Manuel De La Cruz was sleeping in the bedroom on the first floor

before the incident. Juan Manuel De La Cruz was startled by the noise of the explosion and immediately got

up and evacuated the home.

I also asked the occupants of the home to give voluntary handwritten accounts of their experiences during the

fire event. The statement received from Magdalena Tijerina was handwritten by the eldest daughter on scene,

Densy Armas. The second handwritten statement I received was from Alejandra De La Cruz.

Be aware that the stenching chemical added to gas to make it detectable may not warn of a gas leak or the presence of propane or natural gas to all persons in every instance. Instances where the odorant in an odorized gas may be undetectable include: • Odor intensity may fade or be eliminated for a variety of chemical and physical causes, including the oxidation of rusting pipes, adsorption into or sticking onto the interior of pipes or appliances, or absorption into liquids. • Contact with soil in underground leaks may de-odorize or remove odorant from the gas.

Scentinel® E Gas Odorant

Version 2.0 Revision Date 2018-04-02

SDS Number:100000013401 2/16

• Some people have a diminished ability, or inability to smell the stench. Factors that negatively affect a person’s sense of smell include age, gender, medical conditions, and alcohol/tobacco usage. • The stench of odorized gas may not awaken sleeping persons. • Other odors may mask or hide the stench. • Exposure to the odor for even a short period of time, may cause nasal fatigue, where a person can no longer smell the stench. Gas detectors listed by the Underwriters Laboratories (UL) can be used as an extra measure of safety for detecting gas leaks, especially under conditions where the odorant alone may not provide an adequate warning. Gas detectors emit a loud, shrill sound when gas is present and do not depend on sense of smell. Because the odor intensity can fade or people may have problems with their sense of smell, we recommend installing, per manufacturer’s instructions, one or more combustible gas detectors, in suitable locations to ensure adequate coverage to detect gas leaks. Educate yourself, your employees, and your customers with the content of this warning and other important facts associated with the so-called “odor-fade phenomenon.”

GRADE DEFINITION ACTION CRITERIA EXAMPLES

1 A leak thatrepresents anexisting or probablehazard to persons orproperty, andrequires immediaterepair.

Requires immediate repair. Requiresprompt action to eliminate thehazardous conditions.

The prompt action in some instancesmay require one or more of thefollowing:P Implementation an emergency plan(§192.615).P Evacuating premises.P Blocking off an area.P Rerouting traffic.P Eliminating sources of ignition.P Venting the area by removingmanhole covers, barholing, installingvent holes, or other means.P Stopping the flow of gas by closingvalves or other means.P Notifying emergency responders.

P Any leak which, in the judgment ofoperating personnel at the scene, is regardedas an immediate hazard.P Escaping gas that has ignited.P Any indication of gas, which has migratedinto or under a building, or into a tunnel.P Any reading at the outside wall of abuilding, or where gas would likely migrateto an outside wall of a building.P Any reading of 80% LEL, or greater, in aconfined space.P Any reading of 80% LEL, or greater insmall substructures (other than gasassociated substructures) from which gaswould likely migrate to the outside wall of abuilding.P Any leak that can be seen, heard, or felt,and which is in a location that may endangerthe general public or property.

2 A leak that isrecognized as beingnon-hazardous atthe time ofdetection, butrequires scheduledrepair based onprobable futurehazard

Leaks shall be repaired or cleared withinsix months from the date the leak wasreported. In determining the repairpriority, criteria such as the followingshould be considered:

P Amount and migration of gas.P Proximity of gas to buildings andsubsurface structures.P Extent of pavement.P Soil type, and soil conditions (such asfrost cap, moisture and natural venting).

Grade 2 leaks should be reevaluated atleast once every 30 days until cleared. Grade 2 leaks vary greatly in degree ofpotential hazard. Some Grade 2 leaks,when evaluated by the above criteria,may require a scheduled repair withinthe next five working days. Others willrequire repair within 30 days. Duringthe working day on which the leak isdiscovered, these situations should bebrought to the attention of the individualresponsible for scheduling leak repair.

On the other hand, many Grade 2 leaks,because of their location and magnitude,can be scheduled for repair on a normal

Leaks Requiring Action Ahead of GroundFreezing or Other Adverse Changes inVenting Conditions. Any leak which, underfrozen or other adverse soil conditions,would likely migrate to the outside wall of abuilding.Leaks Requiring Action Within Six MonthsP Any reading of 40% LEL, or greater,under a sidewalk in a wall-to-wall pavedarea that does not qualify as a Grade 1 leak.P Any reading of 100% LEL, or greater,under a street in a wall-to-wall paved areathat has significant gas migration and doesnot qualify as a Grade 1 Leak.P Any reading less than 80% LEL in smallsubstructures (other than gas associatedsubstructures) from which gas would likelymigrate creating a probable future hazard.P Any reading between 20% LEL and 80%LEL in a confined space.P Any reading on a pipeline operating at 30percent SMYS, or greater, in a class 3 or 4location, which does not qualify as a Grade 1leak.P Any reading of 80% LEL, or greater, ingas associated substructures.P Any leak which, in the judgment ofoperating personnel at the scene, is ofsufficient magnitude to justify scheduled

TONIGHT A NEIGHBORHOOD IS EVACUATED HOURS AFTER AN EXPLOSION THAT KILLED A CHILD. SHE HAS JUST BEEN IDENTIFIED AS 12-YEAR-OLD LINDA ROGERS. THIS IS WHAT’S LEFT AT THE HOME IN NORTHWEST DALLAS. IT IS TRAGIC. FOUR OF HER FAMILY MEMBERS ARE STILL IN THE HOSPITAL. FIREFIGHTERS CLEARED OUT EVERYONE IN A FOUR MILE RADIUS, INCLUDING AN ELEMENTARY SCHOOL. MORE THAN 700 STUDENTS AT STEPHEN C FOSTER got ON BUSES AND HEADED TO NEARBY CAMPUSES FOR THE DAY. NOW CREWS ARE DESPARELY TRYING TO FIGURE OUT WHAT WENT WRONG.. JUST TWO DAYS AGO A FIRE BROKE OUT AT A HOME THAT SHARES THE SAME BACKYARD ALLEY, AND THE SAME GAS LINE. THEN THURSDAY, ANOTHER FIRE, JUST A FEW DOORS DOWN. A MAN SAYS HIS OVEN EXPLODED ON HIM. INVESTIGATIVE REPORTER TANYA EISERER IS LIVE IN THE NEWSROOM WITH THE QUESTIONS THAT ATMOS WILL BE FORCED TO ANSWER. {***TANYA/VO***}

ATMOS IS GOING TO EXPLAIN WHY THIS HAPPENED, IF THESE THREE INCIDENTS ARE CONNECTED AND IS THIS THE RESULT OF A FAULTY DEVICE THAT’S BEEN THE SUBJECT OF OUR REPORTING FOR YEARS. (--PKG--) (jason evans fire spokesman. forbes house explosion b roll and sot) 082928 we got this call at about 630 this morning. NEIGHBORS IN NORTHWEST DALLAS WOKE UP TO TRAGEDY. EVACUATED FROM THEIR HOME. A HOUSE COLLAPSING FROM A GAS EXPLOSION. (Jason Evans 082940) there was a quick house explosion. AN EXPLOSION SO VIOLENT IT BLEW THE SIDING OF THE HOUSE. AN 11 YEAR OLD IS DEAD. FOUR OTHERS INJURED. (Jason Evans 083040) There have been two other similar incidents that have taken place over the last two days. (PICTURES AND/OR VIDEO OF TWO HOMES ON DURANGO)

THE THREE INCIDENTS –ALL WITHIN A FEW HOUSES OF EACH OTHER -- ARE JUST THE LATEST POSSIBLY INVOLVING AN ATMOS GAS LINE… March 2, 2018

…WE CAN'T FORGET WHAT PROMPTED ALL OF THIS.. THE DEATH OF A LITTLE GIRL. 12 YEAR OLD MICHELLITA ROGERS WAS KILLED 6 DAYS AGO WHEN HER HOME EXPLODED LAST FRIDAY.

HER FAMILY AND FRIENDS WILL SOON SAY GOODBYE WHEN HER FUNERAL BEGINS AT 6:30.

HERE’S WHERE THINGS STAND IN THE NEIGHBORHOOD. ATMOS SHUT OFF GAS TO 2800 HOMES SO THEY CAN REPLACED DAMAGED EQUIPMENT.

THE COMPANY BLAMING WEATHER CONDITIONS FOR SUDDEN GAS LEAKS.

SERVICE WILL BE OUT FOR 3 TO 4 WEEKS. AND MORE THAN 120 CREWS WILL BE WORKING AROUND THE CLOCK.

AND THIS IS THE AFFECTED AREA.

TWO WEEKS AFTER A GAS EXPLOSION KILLED THIS LITTLE GIRL - WE NOW KNOW WHERE THE MOST DANGEROUSNATURAL GAS PIPELINES ARE IN DALLAS COUNTY!

IT WASN’T EASY AND IT WASN’T FAST, BUT WE GOT OUR HANDS ON A MAP SHOWING HUNDREDS OF MILES OF DANGEROUS CAST IRON PIPE CARRYING GAS ALL OVER THE CITY, FROM SOUTH DALLAS TO THE HEART OF THE PARK CITIES.

WE ALL NEED TO PAY ATTENTION TO WHAT TANYA EISERER UNCOVERED.

(--PKG--)

6:40 We smelled a lot of gas when we walked out one day. Meet a couple who live nowhere near the voluntary evacuation zone Atmos created.

In fact BART AND CYNTHIA ZOLNOWSKI don't even have the same kind of pipe being replaced in that neighborhood. They live in the M streets in East Dallas. 7:03 Our neighbors tell us it is a common thing to smell gas They are worried. And they should be. 7:27 No one wants a gas leak. …It's kind of scary WHILE ATMOS CREWS WORK REPLACING LEAKY **STEEL*** PIPES IN NORTHWEST DALLAS, THE ZOLNOWSKIS have what's called cast iron piping near their home. FEDERAL REGULATORS HAVE WARNED OF ITS DANGERS FOR DECADES. In fact the feds have URGED states to replace all cast iron piping. To date… 21 states have replaced cast iron all together. Texas is not one of them. (GRAPHIC) 274420 Should they still have any cast iron pipe in the ground? When you look at the history of cast iron pipe and all its problems I would say absolutely not. DON DEAVER IS A PIPELINE SAFETY EXPERT. 285022 It's a very brittle type of material. 280822 Definitely, it should never be used to transport something this dangerous. (map graphic) There HAS been SOME replacement work done in Dallas. Exactly 49 MILES IN THE PAST THREE YEARS. But there is still 4 hundred and nine miles of pipe running under the city. The same kind of pipe the Feds say is DANGEROUS AND IN UNIVERSITY PARK AND HIGHLAND PARK? THOSE CITIES HAVE AN ADDITIONAL 30 MILES STILL IN THE GROUND. (deaver 331705) it's a very dangerous product and you're exposing the people in Dallas to form of Russian roulette. (atmos heranandez explosion victims 192440) we just came home and I turned the light on and I didn't smell nothing. once I turned the light on it just exploded. SEVEN YEARS AGO A CRACKED CAST IRON PIPE LED TO A GAS EXPLOSION THAT MAIMED DOMINGO MENDEZ AND HIS FAMILY. (atmos hernandez explosion pablo) 193852 "I wouldn't have gotten out if it wasn't for

my dad. (atmos hernandez explosion victims 192806) there's still lives out there at that are at risk because of the old gas lines IN A RECENT MEMO TO COUNTY JUDGE CLAY JENKNS, ATMOS SAYS IT EXPECTS TO REMOVE ALL REMAINING CAST IRON PIPES IN DALLAS BY THE END OF 2023. (Jenkins 03:26) What'd I like to have done, is I'd like to have it done just as soon as possible. I'd like to be able to get it all done this year. DON DEAVER HAS BEEN AN EXPERT WITNESS AND CONSULTANT IN PREVIOUS ATMOS EXPLOSIONS. HE HAS STRONG OPINIONS ON HOW ATMOS HANDLED THIS LATEST EXPLOSION. IN THE TWO DAYS BEFORE THAT DEADLY HOUSE EXPLODED, TWO OTHER HOMES CAUGHT FIRE NEARBY. BOTH WERE NATURAL GAS RELATED. (DEAVER 491927) with that first one going up there, Atmos should have been swarming all over that huge area with an extensive leak investigations before anything else happened. ATMOS FOUND 28 LEAKS NEAR THE HOMES SHORTLY AFTER THE FATAL EXPLOSION. (deaver 505629) To think that you're going not have one leak and not have any others going on but that one single leak and there not any probability of any other problems in the area, it's ludicrious. (atmos presser 5 a.m. 215709) this was truly an extraordinary event. ATMOS OFFICIALS BLAMED UNFORSEEN SHIFTING SOIL CONDITIONS FOR THE DECISION TO REPLACE 27 MILES OF STEEL PIPE IN THAT NEIGHBOHROOD. (atmos presser 5 am. kevin acres) 212326 the way this formation is acting in this amount of rain in this moment, there's no way to have been able to predict, understand or know that this event was going to occur at this time. (DEAVER 174221) I would say that they have a hard road ahead to prove that that was the case that. the likelood that that was a primary cause is slim to none. With the Atmos crisis still unfolding, Deaver leaves us. With this: (Don deaver 481717) I don't think that Atmos does anything that doesn't involve cost as a number one consideration.

(anchor) CALL IT A MISSED OPPORTUNITY- OR A TRAGIC LACK OF URGENCY. BOTTOM LINE- ATMOS KNEW SOMETHING WAS GOING ON IN THE HOURS BEFORE AN EXPLOSION THAT KILLED THIS LITTLE GIRL. WE GOT HOLD OF AN EMAIL SENT BY ATMOS IN THE HOURS JUST BEFORE LINDA MICHELLITA ROGERS DIED TWO WEEKS AGO TODAY. INVESTIGATIVE REPORTERS TELL US WHAT SHE FOUND… (--PKG--)

A house on Durango Drive catches fire Feb. 21. Homeowner David Lemus' face is burned in the fire. (atmos folo 6 p.m. Feb. 27) 00:15 My family is traumatized. The next day, Feb. 22, at a house a few doors down, a man is burned when his stove explodes. Both fires are natural gas related. A day later, Feb. 23, a third gas leak – on the same block a street over - leads to a FATAL house explosion. Three incidents in three days. What was Atmos Energy's response during the escalating crisis? News 8 has obtained emails that gives insight into Atmos' response after the first two fires. On Feb. 22 - 12 hours before the fatal explosion – an email comes from Marlo Sutton, Atmos' director of Regulatory and Compliance. She writes to a Texas Railroad Commission official about the first two fires. She writes: "Atmos crews are continuing to monitor the surrounding area for potential leaks and will make repairs as needed." But she adds, "There have been no evacuations or road closures." HOURS LATER….. MICHELITA RODGERS WAS DEAD. AND AN ENTIRE NEIGHBORHOOD WAS CLEARED OUT. (eiserer atmos deaver one 491927) With that first one going up there, Atmos should have been swarming all over that huge area with an extensive leak investigations before

anything else happened." Don Deaver is a pipeline safety expert. "They should have eliminated the gas pressure and evacuated the people out right away until they prove it was safe." On the morning of the explosion, A Railroad Commission official writes in an email that she'd spoken to Sutton. Sutton told her they repaired a leak the night before the explosion. But clearly there were still more leaks. (eiserer Atmos deaver one 494621) "When a second one goes off, and you still don't go into a full emergency response type of mode, you're just sitting there with a don't fix it until it's broke mentality." According to commission documents, 28 leaks were found in the immediate evacuation area shortly after the explosion. Not only that, the line running in the alley between the homes…. was so leaky… that it couldn't hold pressure when it was capped off. It's something Deaver says they should have done after the first fire. 322407 Atmos has found out many years ago that there's money to be made to be cutting corners on regulatory and safety compliance.

ATMOS PLANS TO FINISH ITS MASSIVE PIPE LINE REPLACEMENT PROJECT THIS WEEKEND. THEY SAY ONLY 5 PERCENT OF THE WORK REMAINS IN THIS NORTHWEST DALLAS NEIGHBORHOOD. HUNDREDS OF PEOPLE HAVE BEEN WITHOUT GAS SERVICE FOR MORE THAN THREE WEEKS. TODAY WE LEARNED MORE ABOUT THE DEADLY HOME EXPLOSION THAT STARTED ALL OF THIS. THE NTSB’S PRELIMINARY REPORT REVEALS GAS LEAKS WERE DETECTED A MONTH BEFORE THE BLAST THAT KILLED A LITTLE GIRL.

NEW 8S TANYA EISERER IS LIVE IN THE DALLAS NEWSROOM. THIS REPORT SHOWS THAT ATMOS KNEW THAT THERE WAS TROUBLE IN THAT NEIGHBORHOOD. (TANYA) YES IT DOES. THERE ARE SOME KEY DETAILS IN THIS PRELIMINARY REPORT. ONE THING THAT WE NOW KNOW IS THAT NTSB INVESTIGATORS FOUND A CRACK ALL THE WAY AROUND A 2 INCH GAS LINE BEHIND THE HOUSE ON ESPANOLA DRIVE THAT EXPLODED LAST MONTH KILLING THAT 12 YEAR OLD GIRL. WE ALSO KNOW THAT ATMOS CREWS HAVE BEEN RESPONDING TO LEAKS IN THE AREA SINCE THE START OF THE YEAR, NEARLY 2 MONTHS BEFORE THE DEADLY EXPLOSION. IF YOU’LL RECALL THERE WAS ALSO ANOTHER EXPLOSION AND A FIRE AT HOUSES A STREET OVER FROM ESPANOLA 2 DAYS BEFORE THE BLAST YET NO ONE WAS EVACUATED UNTIL AFTER THE YOUNG GIRL DIED… ATMOS IS ALSO REPLACING 27 MILES OF IN THAT SURROUNDING NORTHWEST DALLAS AREA. THE COMPANY HAS BLAMED EXTRAORDINARY RAINS COMBINED WITH SHIFTING CLAY SOIL FOR CAUSING WHAT IT SAID WERE UNPRECEDENTED LEAKS. AN EXPLANATION THAT’S NOW IN QUESTION, SAYS THE FORMER HEAD OF THE FEDERAL AGENCY THAT REGULATES POPELINES. (Brigam A. McCown sound:) this also casts some doubt into atmos' claims that this was a weather related event. Significant rain fall can exacerbate a situation. It can make it easier for leaking gas to find a pathway to the surface but these lines have been leaking for some time. … (eiserer mccown lawyer 1112) I don't get the sense that atmos is in a hurry to get this pipe replacement done and I think atmos has to have a sense of urgency in getting the older pipe out of the ground. March 27, 2018 {***JOHN/JIB***} YOU MIGHT HAVE HEARD THIS ONE BEFORE... THEY SMELLED GAS... AND THEN A HOME EXPLODED! {***JOHN***} BUT, WE'RE NOT TALKING ABOUT THE DEADLY EXPLOSION IN DALLAS, THAT SET OFF THE CURRENT ATMOS CRISIS. NO... THIS WAS MONTHS BEFORE. AND JUST LIKE IN DALLAS... ATMOS NEVER EVACUATED ANY HOMES! LISTEN TO WHAT INVESTIGATIVE REPORTER TANYA EISERER DUG UP- [TAKE VO]

{***VO***} IN THIS WFAA ORIGINAL. (--PKG--)

THE CHRISTMAS DECORATIONS STILL HANG IN WHAT REMAINS OF THE HOUSE OF COLGATE LANE. (EISERER ATMOS INTV 0710) It's a shell. It's unbelievable. JON HIGGINBOTHAM MADE THE FIRST CALL TO IRVING 911 ON NEW YEAR'S EVE ABOUT 7:30 P.M., ALMOST 10 HOURS BEFORE THE HOUSE EXPLODED. (Irving open records material 1 1538, 911 CALL) There was a really strong smell of natural gas. (Irving open records material 1 1611, 911 CALL) It was strong, really, really strong kind of like I could light a match and the whole neighborhood would blow up. HIGGINBOTHAM WAS WITH HIS PREGNANT WIFE. (Eiserer atmos intv 0857) It smelled like I had turned on my gas range and put my nose right up to the range. It was that strong of a smell. ALMOST 10 HOURS AFTER HIGGINBOTHAM'S CALL, A WOMAN MADE A FRANTIC 911 CALL. (Irving open records material 1) 2413 I'm on colgate and connor and the house blew up. NATURAL GAS HAD MIGRATED FROM A GAS MAIN LEAK NEXT TO THE HOUSE AS ATMOS CREWS WORKED TO REPAIR THE LEAK. THE SLEEPING PEOPLE INSIDE THE HOUSE BARELY MADE IT OUT ALIVE. (Irving open records material 1) 2426 Oh my god, they're screaming. They're screaming. SO WHY DIDN'T ATMOS EVACUATE THE FAMILY FROM THE HOUSE OR THE SURROUNDING NEIGHBORHOOD BEFORE THE EXPLOSION? THE COMPANY DID NOT RESPOND TO OUR REQUEST FOR COMMENT. NEWS 8 OBTAINED THE IRVING FIRE DEPARTMENT'S INVESTIGATIVE RECORDS. THEY SHOW A WOMAN LIVING IN THE HOUSE ASKED AN ATMOS CREW MEMBER WORKING OUTSIDE TO CONTAIN THE GAS LEAK IF "THERE WAS A NEED TO EVACUATE. THE ATMOS REPRESENTATIVE STATED THAT "THERE WAS NOT A NEED." THE WOMAN TOLD INVESTIGATORS SHE ASKED ATMOS CREWS AT LEAST THREE TIMES "IF IT WAS SAFE TO REMAIN IN THE HOME."

(eiserer mccown 1348) Anytime you smell gas you have to take it very seriously. BRIGHAM MCCOWN IS THE FORMER HEAD OF FEDERAL AGENCY THAT REGULATES PIPELINES. (Eiserer Mccown 1355) When you are faced with evidence that there is a leak in the area, the gas need to be turned off and people should not be left inside. THE RELUCTANCE TO EVACUATE IS SIMILAR TO THEIR ACTIONS IN NORTHWEST DALLAS LAST MONTH. ON A WEDNESDAY, ONE HOUSE EXPLODED FUELED BY A GAS LEAK. THE NEXT DAY, ANOTHER CAUGHT FIRE, AGAIN IGNITED BY LEAKING NATURAL GAS. STILL ATMOS DID NOT EVACUATE THE NEIGHBORHOOD. IT WASN'T UNTIL A THIRD HOUSE EXPLODED, KILLING A 12 YEAR OLD, THAT ATMOS EVACUATED RESIDENTS. (Eiserer mccown 1445) One of the concerns I have is whether or not there is a lackadaisical approach to safety. I think we can all say that we over did it. we were inconvenienced. We left our homes for a couple of hours but that is a far better outcome and that is a preferable outcome than to being told don't worry about it, and then have your home blow up. ON NEW YEAR EVE'S NIGHT IN IRVING, ATMOS CREWS ARRIVED ABOUT 9 P.M. THEY BEGAN DIGGING TRYING TO FIND THE LEAK IN THE 45 YEAR OLD SIX INCH PLASTIC PIPE. (Irving open records material 1) 1838 We're at colgate and oconnor and we just need a fire truck out here. AROUND 3 A.M., ATMOS ASKED THE FIRE DEPARTMENT FOR HELP CONTROLLING TRAFFIC. IN A CALL TO FIRE DISPATCH, AN ATMOS CREW SOUNDED FRUSTRATED THAT THEY COULDN'T CONTAIN THE SERIOUS LEAK. IT WAS CAUSING THEIR EQUIPMENT TO STALL. (IRING OPEN RECORDS 1 1853) We've been on scene for about four hours. And it's starting to migrate and our backhoe's kind of started fluttering. A FIRE CREW HAD BEEN ON SCENE FOR TWO HOURS WHEN THE HOUSE BLEW UP. THAT WAS JUST BEFORE 5 A.M. (Irving explosion comp reel 0043 female resident) I come out and open the curtains and it's bright orange. THE FIRE INVESTIGATATOR CONCLUDED MIGRATING GAS CAUSED THE FURNACE PILOT LIGHT TO IGNITE. (IRVING HOUSE EXPLOSION COMP REEL 0317) it was pretty scary. I've never been close to a fire like that. or seen a house burn like that.

ONLY HOURS AFTER THE EXPLOSION, A FIRE DEPARTMENT SPOKESMAN DEFENDED THEIR DECISION NOT TO EVACUATE. (IRVING FIRE EXPLOSION COMP REEL 0719) It's not out of the ordinary for us to have a gas leaks, natural gas leaks, but it's a rare that you actually evacuate a house especially in situations like this. MCCOWN SAYS THE COMPANY NEEDS TO UNDERTAKE A TOP TO BOTTOM REVIEW OF ITS SAFFETY PROTOCOLS. (EISERER MCCOWN 1510) Atmos needs to go back to drawing books and take a look at their safety. AT THE STATE LEVEL, ATMOS IS REGULATED BY THE TEXAS RAILROAD COMMISSION. COMMISSION RECORDS INDICATE IN THE AFTERMATH OF THE IRVING EXPLOSION ATMOS CREWS DISCOVERED A LEAKING "SIX INCH MECHANICAL COUPLING." 1140 (me ) so when the house explodes there's a woman her child and another person upstairs and they barely escape? I cant' believe they escaped. The house is literally a shell. A SHELL NO LONGER OCCUPIED. (NATS OF ME AND HIBBINGBOTHAM AT THE BACK OF THE HOUSE.) THE HOUSE IS SO DAMAGED THAT IT LIKELY WILL BE TORN DOWN. (Eiserer Atmos Intv, Higginbotham) 1606 You let the people stay in the house. your machines weren't working but you let people's lives be in danger when it was so unnecessary. It's really unbelievable.

IT’S A DANGER YOU CANNOT SEE, YOU CANNOT SMELL BUT JUST ONE BAD MOVE CAN BE A MATTER OF LIFE OR DEATH.

TANYA EISERER INVESTIGATES IN THIS WFAA ORIGINAL.

(--PKG--)

(Caldwell body cam 0659) It blowed completely up. WHAT YOU ARE WATCHING IS THE AFTERMATH OF A NATURAL GAS EXPLOSION IN THE TINY TOWN OF CALDWELL TEXAS. (CALDWELL BODY CAM 011) The gas meter's blown off. There's a straight line spewing

somewhere. THE POLICE BODY CAM VIDEO CAPTURED THE MOMENTS AFTER THE HOUSE EXPLODED IN APRIL. (Judy begining 34) The first thing I saw is big round ball of fire(Judy beginning 26) All I could think of was Gene. It was Gene's house. . JUDY'S CLIFFORD'S 92 YEAR OLD NEIGHBOR WAS TRAPPED INSIDE. (judy and gene 0453) When I heard his voice my heart just. It was good to hear his voice. (Caldwell body cam 0040) We got you. We're not going to let you go. RESCUERS HELPED GENE BARBER ESCAPE THE WRECKAGE OF HIS HOME. (CALDWELL BODY CAM 0235) It got your face. your hair's gone. (Caldwell body cam 0734) How in the hell does something like this happen? THEY'RE STILL ASKING THAT QUESTION IN CALDWELL TWO MONTHS LATER. HERE'S THE THING: IT WASN'T GENE BARBER'S GAS LINE THAT WAS LEAKING. 1729 (ME) It had been installed just a few years ago but his neighbor's line had been installed in 1965 and it was leaking. (Judy) Oh my gosh. (NATS OF BOTS ASKING) 2036 Tanya is that him? (Judy 2056) How are you? Oh my god. Oh my gosh it's so good to see you. (2102 barber) it's good to be here. BARBER IS THE COUNTY'S RETIRED SHERIFF. HE WAS JUST RECENTLY RELEASED FROM THE HOSPITAL. (barber 2114) We never smelled gas no where. ....When I went in that bathroom and flipped the switch, the whole damn thing blew up. (2854) Ordinarily, you can smell it. Two of the guys that investigated it told me there's three things that cause it: one thing you get old. You can't smell. He said you're 93 that could be it. I said no that wasn't it. They said if it filters through dirt it will take the egg smell out and that' what I'm going on. EXPERTS CALL IT ODOR FADE. YOU SEE OUT OF THE GROUND, NATURAL GAS HAS NO SMELL. COMPANIES LIKE ATMOS PUT CHEMICALS IN IT ON PURPSE TO MAKE IT SMELL LIKE ROTTEN EGGS. BUT OVER TIME THE CHEMICALS CAN

FADE.. ODOR FADE'S BEEN BELIEVED TO BE A FACTOR IN EXPLOSION AFTER EXPLOSION. IN 2011, AN AGING ATMOS CAST IRON LINE CAUSED AN EXPLOSION AT THE MENDEZ HOME IN DALLAS. THERE WAS NO SMELL AT ALL. (hernandez explosion victims) 025128 once I turned the light on it just exploded. DOMINGO MENDEZ, HIS WIFE AND THEIR SON STILL BARE THE SCARS. (Hernandez explosion victims 192440) I didn't smell nothing. A YEAR EARLIER, PEGGY MANTHEIY AND HER HUSBAND WERE BLOWN OUT OF THEIR BED AT THEIR IRVING HOME. (Bhdn atmos folo color fade 0124) Had I smelled anything I would have gotten out of the house. HER HUSBAND DIED DAYS LATER. (1359-433-1 0118) I'm in so much pain. cop. I know. I know you are. guy. oh dear god. .. it hurts so much. LAST SUMMER, STEHENVILLE POLICE BODY CAM RECORDED THE AGONZING MOMENTS AFTER RAUL PEDROZA CAUGHT FIRE. (1359-433-1 008) the stove was on. (burn victim) It's still on. (cop) Was it gas? Yes. (burn victim) help me please. Help me please. NEITHER PEDROZA NOR HIS FRIEND WHO WAS ALSO BURNED SMELLED THE LEAKING NATURAL GAS. NEITHER REALIZED AN OPEN GAS VALVE HAD ALLOWED GAS TO POOL INSIDE THE HOME. (1048) Although he didn't' die, I would not want to trade places with him. he's in a horrible state right now due to the burns that he suffered. ATTORNEY DEAN GRESHAM IS SUING ATMOS NOT OVER THE LEAK ITSELF. INSTEAD, THE LAWSUIT CONTENDS THE COMPANY FAILED TO WARN PEDROZA THE ODOR ASSOCIAED WITH NATURAL GAS CAN FADE. 1810 it's important for your viewers to see this horrific video because it really represents the extreme danger that this type of odorant fade explosion can result in. (standup ) So is atmos doing enough to let customers know they might not smell the

leaking natural gas? (end standup) IN A NEWS 8 INVESTIGATION THAT AIRED IN 2010, ATMOS DISMISSED THE PHENONMENON OF ODOR FADE. THE COMPANY CALLED IT MORE "THEORY THAN FACT." THIS TIME WHEN WE REACHED OUT, THE COMPANY AGREED THAT IN "CERTAIN RARE CONDITIONS" "THE ODOR INTENSITY CAN BE DIMINISHED." (Gresham 0903) Maybe they won't want to make customer realize just how important odorant fade is but also how dangerous odorant fade is. (1359-433-1, from the Stephenville body cam) 0138 oh god. Oh my god.oh dear god help me. oh lord. (Cop 2120) this is why I don't' like gas man. (CALDWELL BODY CAM 0819) it's an explosion. 0822 how it happened? I don't know. BACK IN CALDWELL, BARBER IS THANKFUL TO BE ALIVE … (NATS FROM THE BOB WILLS SONG HE SANG US) HIS BURNS ARE SLOWLY HEALING. 2515 it wasn't my time. But this time I thought it was. THE WRECKAGE OF BARBER'S HOME SERVES AS A REMINDER OF A SILENT AND SOMETIMES ODORLESS DANGER. (JUDY 58) I don't know if you can imagine walking into your house, thinking everything's ok and just flip a switch and have something like this happen. Nov. 12, 2018

{***JOHN***} REMEMBER THIS FACE? MICHELITA ROGERS. KILLED IN DALLAS WHEN HER HOME EXPLODED. [TAKE :ON CAM] THAT WAS ALMOST A YEAR AGO. AND YOU SHOULD KNOW: GAS CONTINUES TO LEAK OUT OF THE ATMOS SYSTEM... PUTTING YOUR FAMILY AT RISK. AND COSTING YOU MONEY. TONIGHT, TANYA EISERER INVESTIGATES.

(--PKG--)

(Facebook video 08) Lighting bubbly gas…. So Atmos came. They said we'll come back in five days and fix this. look at this. WHEN YOU SEE A FACEBOOK VIDEO

You see that flame.

YOU MAY NOT TAKE IT SERIOUSLY.

(Facebook 14 ) I lit the natural gas that is bubbling out of my yard. …

I’m reading the comments, I’m dumb for lighting it…

JED ALLSUP NOW KNOWS THAT THE BUBBLING GAS …WAS FAR FROM FUNNY. (NATS) HE SHOT IT HOURS BEFORE THE FIRST OF THREE HOUSE EXPLOSIONS ONLY BLOCKS AWAY IN NORTHWEST DALLAS. THE THIRD EXPLOSION KILLED 12-YEAR-OLD MICHELITA ROGERS. (emotional) (Allsup 1030) I don't know what I'd do if I lost one of my kids. (scratches his chin, obvious emotion) That's devastating. (deep breath) That's crazy. ALLSUP'S LEAK… WAS AMONG MORE THAN FIVE THOUSAND THREE HUNDRED NORTH TEXAS GAS LEAKS REPORTED BY ATMOS IN THE FIRST SIX MONTHS OF 2018. 26 HUNDRED OF THOSE LEAKS WERE THE MOST SERIOUS TYPE.. CALLED GRADE ONE. THE TEXAS RAILROAD COMMISSION, WHICH REGULATES GAS COMPANIES, REQUIRES THOSE TYPE OF LEAKS BE REPAIRED "IMMEDIATELY." WFAA REVIEWED HOW LONG IT TOOK ATMOS TO FIX THOSE LEAKS. WE MAPPED A 160 OF THOSE MOST SERIOUS LEAKS, THAT TOOK A WEEK OR MORE TO REPAIR. (Pull up the 150 leaks from map) ONE DALLAS COUNTY GRADE 1 LEAK TOOK ALMOST *FIVE MONTHS* TO FIX. (Don Deaver interview 1506) Leaks don't heal themselves. They're like people. you get worse with time.

DON DEAVER IS AN EXPERT ON PIPELINE SAFETY. HE HAS BEEN HIRED BY MICHELLITA'S FAMILY. (Deaver 919, Tanya) Is there a financial disincentive for gas companies to fix leaks? (Deaver 950) This affects their bottom line, the cost to go out and find these leaks (TRIMMED THE SECOND PART OF THIS SOUND) ATMOS ALSO MAY HAVE BEEN SLOW AT TIMES TO FIX LESS SERIOUS GRADE 2 LEAKS, according to Their own reports filed with state regulators. THOSE ARE REQUIRED TO BE REPAIRED WITHIN SIX MONTHS. YET THE REPORTS SHOW DOZENS OF GRADE 2 LEAKS IN NORTH TEXAS WENT UNREPAIRED FAR LONGER. SO WHAT ABOUT ALLSUP'S LEAK? (NATS FROM THE VIDEO) ATMOS CLASSIFIED THAT AS A GRADE 2. THAT MEANT ATMOS WOULD HAVE HAD *SIX MONTHS* TO FIX IT. (Deaver 2049) If you can see or hear a leak, it's a class one. There's no doubt. DEAVER SAYS THIS IS A TEXTBOOK EXAMPLE OF ATMOS MISCLASSIFYING A LEAK. (NATS) AFTER ALLSUP POSTED THAT VIDEO AN ATMOS CREW SHOWS UP WITH HOURS TO FIX IT. (NATS) ATMOS OFFICIALS DECLINED AN ON-CAMERA INTERVIEW. BUT IN A WRITTEN STATEMENT THE COMPANY SAYS IT HAS SPENT 3 BILLION DOLLARS MODERNIZING ITS INFRASTRUCTURE OVER THE PAST 13 YEARS, AND PLANS TO SPEND 3 BILLION *MORE* OVER THE NEXT FIVE YEARS. IN THE MEAN TIME, GAS CONTINUES TO LEAK OUT OF THEIR SYSTEM. HOW MUCH? WFAA DISCOVERED THAT SINCE 2010, ACCORDING TO ITS OWN REPORTS!-- ATMOS SAYS IT LOST OR COULDN'T ACCOUNT FOR 98.6 MILLION DOLLARS

WORTH OF NATURAL GAS IN ITS PIPELINES IN DALLAS COUNTY *ALONE.* THAT'S 9.7 BILLION CUBIC FEET. SO HOW DOES THAT COMPARE? LET'S LOOK AT THE CITIES OF HOUSTON AND DALLAS. DALLAS HAD A LEAKAGE RATE IN 2016 TWICE THAT OF HOUSTON. THE PROVIDER IN HOUSTON IS CENTERPOINT. ATMOS SAYS THE MISSING GAS ISN'T NECESSARLY ALL CAUSED BY PIPE LEAKS. THE COMPANY SAYS A PORTION COULD BE DUE TO INACCURATE GAS FLOW MEASUREMENTS. SO WHO ENDS UP PAYING? WELL, YOU DO. STATE LAW ALLOWS ATMOS TO PASS ALONG MUCH OF THE GAS IT CAN'T ACCOUNT FOR TO CUSTOMERS. (Eiserer clay jenkins 2310) Any amount of leakage is a concern to the public. COUNTY JUDGE CLAY JENKINS IS DEMANDING THAT ATMOS MOVE FASTER TO MODERNIZE ITS NORTH TEXAS PIPES. MUCH OF IT WAS INSTALLED BEFORE 1940. (eiserer clay jenkins 355) You need to know what's underneath your house of worship, your kid's playground, your neighbor's house. JENKINS SAYS A LACK OF OVERSIGHT BY THE TEXAS RALROAD COMMISSION PUTS THE PUBLIC IN DANGER. (EISERER CLAY JENKINS 2502) We have a very lax regulatory system here in Texas. ATMOS PAID ABOUT $195,000 IN PENALTIES THE PAST FIVE YEARS. IF THAT SOUNDS LIKE A LOT, CONSIDER ATMOS EARNED ABOUT 3 BILLION DOLLARS SINCE 2005. (eiserer clay jenkins 2442) It's pocket change? It's pocket change yes. but it's not about taking money from them, it's about finding a way to expedite replacement HERE'S SOME OF THAT LAX REGULATION IN ACTION. THIS PAST NEW YEARS'S EVE ATMOS CREWS HAD BEEN ON SCENE FOR EIGHT HOURS TRYING TO REPAIR A LEAK IN IRVING. WHILE CREWS WORKED, GAS MIGRATED TO A HOME NEARBY.

ACCORDING TO IRVING FIRE DEPARTMENT RECORDS, AN ATMOS CREW MEMBER TOLD THE CONCERNED FAMILY THERE "WAS NOT A NEED TO EVACUATE THE HOME." (911 CALL) "Oh my god, they are screaming." THE HOUSE … BLEW UP. AND THE FAMILY *BARELY* ESCAPED. RAILROAD COMMISSION INVESTIGATORS FOUND THAT THE "GRADE ONE LEAK HAD NOT BEEN CONTINUOUSLY MONITORED TO DETERMINE WHETHER AN EVACUATION WAS MANDATORY." THE PENALTY: 16,000 DOLLARS. (5513 TED LYON) The Texas Railroad Commission is supposed to regulate Atmos energy and they do a very poor job of it, almost don't do anything. TED LYON REPRESENTS THE FAMILY OF MICHELITA ROGERS, THE LITTLE GIRL KILLED IN THE FEBRUARY EXPLOSION IN NORTHWEST DALLAS. (Eiserer bots atmos ted lyon 0445) They need to clean up their act before any more kids or parents or brothers or sisters or mothers or fathers or killed because of their leaking gas. They really do.

A DEADLY EXPLOSION, KILLING A 12 YEAR OLD GIRL.

ALL OF IT, STEMMING FROM AN ATMOSNATURAL GAS LEAK. AND NOW ONE LAWMAKER IS GEARING UP FOR A FIGHT! OUR TANYA EISERER JOINS US IN THE NEWSROOM.

(tanya)

REP. RAFAEL ANCHIA REPRESENTS THIS DISTRICT, AND AS YOU CAN IMAGINE, WHAT HAPPENED OUT THERE HIT HOME PRETTY HARD WITH HIM.

HE’S SEEN OUR REPORTING, HIGHLIGHTING THE MASSIVE LEAKS IN ATMOS’ SYSTEM, ITS AGING PIPES AND EXPOSING GAPS IN REGULATION.

TO THAT END, HE’S PROPOSING A SLATE OF BILLS THAT WILL HODL ATMOS AND OTHER OPERATORS MORE ACCOUNTABLE, AND TO PROD STATE

REGULATORS TO DO A BETTER JOB … ALL IN THE HOPES OF PREVENTING FUTURE TRAGEDIES.

(--PKG--)

They are images of a 12-year-girl taken too young.

Killed in a natural gas explosion in her northwest Dallas home 10 months ago.

120 In Texas, in 2018, these kinds of things shouldn't be happening.

State rep. Rafael Anchia represents the district where Michellita Rogers died. Hers the third of three house explosions to occur in that neighborhood this past February.

1859 I don't want anybody else in the community to have to deal with that tragedy again.

The bills Anchia plans to propose would:

Dramatically accelerate the replacement of aging pipe.

Significantly increase fines.

Make available a searchable list of enforcement actions.

Create a real-time, up-to-date base of natural gas leaks.

230 That way the public can help us keep these operators accountable as well.

Recall that Atmos didn't notify state regulators until after the second home exploded in northwest Dallas. They didn't have do it sooner because right now no reporting timeline.

713 what we want to make sure is that after explosion no. 1 we have railroad commission investigators on site immediately.

He’d also require all natural gas related deaths and injuries be reported to state regulators. That's currently not always done.

The Texas Railroad Commission regulates oil and gas operators like Atmos. As it stands now, its members can take campaign contributions at any time from the people and companies it regulates.

1242 What's the problem with members of the railroad commission being able to raise money from the very people that they regulate?

1315 it creates at least an appearance of impropriety 1335 we need to make sure that there are clear lines about when you can and can not take money.

Anchia knows he's in for a fight, but he vows that Michellita's death will not be vain.

128 we are a wealthy state. We have the ability to have a safe system. And we need to make sure that the operators of this system are accountable to the people of Texas.

Tag: You may be surprised to find out that the Texas Railroad Commission does not regulate railroads so one of the other Anchia’s changes would be simple as changing the commission’s name.

(anchor) WE DON'T KNOW OFFICIALLY WHAT LED TO THE EXPLOSION THAT KILLED MICHELITA ROGERS. BUT WE DO KNOW- FOR YEARS, WE'VE REPORTED ON A VARIETY OF DIFFERENT ISSUES INVOLVING GAS LINES- AND THE PROBLEMS SHOW UP IN ALL KINDS OF NEIGHBORHOODS. INVESTIGATOR CHARLOTTE HUFFMAN TAKES US BACK TO WHERE IT ALL STARTED.

(--PKG--) (Neighbor / October 2006 / SOT 00:53) NATS … It just blew up, shook my whole house, you would've thought a bomb had gone off (Video from 1:00-1:15) THE NEIGHBORS WHO LIVED IT WILL NEVER FORGET. WYLIE TEXAS, OCTOBER 2006. A PREDAWN EXPLOSION LEVELS AN ELDERLY COUPLE'S HOME, KILLS THEM BOTH ... AND TRIGGERS WHAT WOULD BECOME A DECADE LONG NEWS 8 INVESTIGATION. (2:11) THE STATE DETERMINED A COMPRESSION COUPLING HAD FAILED CAUSING NATURAL GAS TO LEAK INTO THEIR HOME. (4:30) THE COUPLING, WAS A TYPE PRONE TO FAILURE (29:15) WHEN THE NOTORIOUSLY ELASTIC NORTH TEXAS SOIL EXPANDS, CONTRACTS AND PULLS ON A PIPE... ( 11:59 pipeline safety engineer, Don Deaver,) "this has been known for a long time. These warnings known for many years." OUR INVESTIGATIVE TEAM DISCOVERED *THAT SAME* COUPLING CONNECTED GAS lines UNDER AN ESTIMATED 100 THOUSAND NORTH TEXAS HOMES .... (5:40) NATS POP... BUT REPLACING THEM WOULD TAKE TIME AND COST TENS OF MILLIONS. SO THEY WERE LEFT IN THE GROUND ... AND NORTH TEXANS AGAIN PAID WITH THEIR LIVES. (shot of cemetary / 5:52) (neighbor / 6:18) there was just a boom. damage was extensive. IN 2007, ANOTHER EXPLOSION. THIS TIME IN CLEBURNE. 2 ARE DEAD .... (32:47) AND WFAA AGAIN CALLED INTO QUESTION THE ATMOS' INACTION.

(7:08) Brett: do those things need to come out of the ground? (Atmos rep) I can't say that. (47:05) AFTER WFAA'S REPORTS AIRED... nats: 37:08 voting RAILROAD COMISSIONERS ORDERED ATMOS TO DIG UP SOME OF THE OLDER COUPLINGS AND REPLACE THEM IMMEDIATELY. FOUR YEARS LATER ... in 2011, ANOTHER EXPLOSION. THIS ONE CRITICALLY INJURES 3 FAMILY MEMBERS including a 5 year old boy, who was left with an obvious reminder of what happened (shot of scars at 1:10) (sept 18 2011 / 1:19 / Domingo Mendez, home exploded ) I just felt a ball of fire, just burning. Then a few seconds after that I just woke up on the floor. IN THIS FAMILY'S CASE, IT WASN'T A FAULTY COUPLING ... RATHER, A 19-INCH FRACTURE IN A NEARBY 80 YEAR-OLD CAST IRON PIPE. BUT JUST LIKE THE FAULTY COUPLINGS .... WFAA LEARNED .... THESE PIPES HAD A LETHAL LEGACY OF FAILURE TOO. (don deaver, pipeline safety engineer / 3:08 ) this is an obsolote, inferior material that degraded over time and sees more and more things stressing it and causing it to fail. It's a collision course, perfect storm. (4:09) WHAT'S MORE ? .. WFAA INVESTIGATORS UNCOVER EVIDENCE ... GOVERNMENT REGULATORS WARNED GAS COMPANIES ABOUT THE DANGER OF CAST-IRON PIPES DECADES AGO.(4:31) HOUSTON'S GAS SUPPLIER HEEDED WARNINGS TO PHASE THEM OUT AND THE CITY HAS BEEN CAST-IRON-FREE SINCE THE 90S. BUT NOT SO IN DALLAS. ( 17:17) AS A RESULT, THE STATE CITED ATMOS ...... AND DALLAS COUNTY JUDGE CLAY JENKINS CALLED ON THE COMPANY TO TAKE AGRESSIVE ACTION. (nats: 20:51 / Judge Clay Jenkins) they need to remove it from the ground as soon as possible FAST FORWARD TO TODAY ... WFAA'S I-TEAM SITS DOWN WITH JUDGE JENKINS FOR A SADLY SIMILAR INTERVIEW. (14.57)

My concern is that we have areas of the system that are aged out, that are old, that are more subject to leaks and breaks. Back when I started talking to folks about this, a little boy in Oak Cliff who'd been badly burned, now we're going to bury a little girl tomorrow, I want to do everything in our power to keep our people safe.
