COMMONWEALTH OF KENTUCKY

BEFORE THE PUBLIC SERVICE COMMISSION

In the Matter of:

CARROLL TON UTILITIES

ALLEGED FAILURE TO COMPLY WITH 49 CFR § 191.9(a)

ORDER

CASE NO. 2015-00178

Carrollton Utilities ("Carrollton") is a municipal gas operator of a distribution

pipeline system in the city of Carrollton, Kentucky. Pursuant to KRS 278.495 and 49

U.S.C. § 60105, the Commission has jurisdiction to regulate safety standards of

intrastate pipeline facilities including gas facilities "owned or operated by any public

utility, county, or city."

On May 27, 2014, a house to which Carrollton provided gas service exploded in

Carrollton, Kentucky. The resulting fire destroyed the residence from which it

originated . No injuries resulted from the explosion. The city of Carrollton Fire

Department was unable to ascertain the explosion's cause; however, the fire

department determined that the explosion originated in the house's basement. As

noted in Commission Staff's Incident Investigation Report ("Investigation Report") 1 the

distribution system line serving the residence had a Maximum Allowable Operating

Pressure of 60 pounds per square inch gauge ("psig"). However, at the time of the

incident the distribution system line was operating below the maximum at approximately

1 Attached as the Appendix.

35 psig. Because they were destroyed in the incident, the gas meter and service

regulator could not be examined.

49 CFR § 191.9(a) provides that "[e]xcept as provided in paragraph (c) of this

section, each operator of a distribution pipeline system shall submit Department of

Transportation Form RSPA F 7100.1 as soon as practicable but not more than 30 days

after detection of an incident required to be reported under § 191.5."

49 CFR § 191.5 states that "[a]t the earliest practicable moment following

discovery, each operator shall give notice in accordance with paragraph (b) of this

section of each incident as defined in § 191.3."

49 CFR § 191.3 defines an incident, in part, as one involving:

(ii) Estimated property damage of $50,000 or more, including loss to the operator and others, or both, but excluding cost of gas lost;

(3) An event that is significant in the judgment of the operator, even though it did not meet the criteria of paragraphs (1) or (2) of this definition.

The city of Carrollton Fire Department report estimated the losses from this

incident as $150,000 in property damage and $70,000 in contents. Due to both the

dollar value of the losses incurred in this incident as well as the significant nature of the

event, the explosion was reportable pursuant to 49 CFR § 191.9(a). Carrollton Utilities

was therefore required to submit the requisite report within 30 days, which ran through

June 26, 2014. However, Carrollton Utilities did not submit the report until over 60 days

later, on July 28, 2014. Accordingly, the Commission finds that prima facie evidence

exists that Carrollton has failed to comply with 49 CFR § 191.9(a), through failing to

submit the requisite report within 30 days.

-2- Case No. 2015-00178

We therefore find that a formal investigation into the incident that is the subject

matter of the Investigation Report is necessary. This investigation will determine

whether Carrollton violated 49 CFR § 191.9(a), and, if it did, whether any reason exists

why penalties should not be assessed under KRS 278.992.

The Commission, on its own motion, HEREBY ORDERS that:

1. Carrollton shall submit to the Commission, within 20 days of the date of

this Order, a written response to the allegations contained in the Investigation Report

and the alleged regulatory violation as set forth in the findings above.

2. Carrollton shall appear on September 15, 2015, at 10:00 a.m., Eastern

Daylight Time, in Hearing Room 1 of the Commission's offices at 211 Sower Boulevard

in Frankfort, Kentucky, for the purpose of presenting evidence concerning the alleged

violation of 49 CFR § 191.9(a), and showing cause why it should not be subject to the

penalties prescribed in KRS 278.992(1) for the alleged violation.

3. The September 15, 2015 hearing shall be recorded by videotape only.

4. The Investigation Report in the Appendix to this Order is made a part of

the record in this case.

5. Any requests for an informal conference with Commission Staff shall be

set forth in writing and filed with the Commission within 20 days of the date of this

Order.

May 28,2014

This incident occurred at 1104 11th Street in Carrollton, Carroll County, Kentucky, at approximately 14:00 hours (Eastern Time) on May 27, 2014. An explosion occurred initially subsequently followed by a fire which destroyed the residence. There were no injuries to occupants of the home that required inpatient hospitalization. (See Attachment B.)

Response to Incident:

Carrollton Utilities Carrollton Utilities personnel arrived on scene at approximately 14:15 hours. Carrollton fire incident commander Mike Terrell requested that the gas service be shut off to the residence. The area immediately around the meter set assembly was engulfed by the structure fire denying access to the meter valve. Utility personnel then went approximately 15 fe.et prior to the meter set assembly and excavated a hole and squeezed the flow of gas off there. Utility personnel then conducted a gas leakage survey of the area around the incident site to determine if any gas leakage was present. No gas leaks were detected. Refer to Attachment B.

Incident Investigation:

Gas Pipeline Safety Branch staff ("Staff'), Joel Grugin and Bill Aitken, arrived at the incident scene on May 28 at approximately 08:15 hours.

Pipeline pressure charts, produced by the operator, were reviewed by Staff and the charts indicated that, at the time of the incident, the operating pressure of the distribution system was approximately 35 psig, below the system Maximum Allowable Operating Pressure ("MAOP") of 60 psig. The PHMSA Incident report showed that the MAOP of the system was 90 psig, this is incorrect, 60 psig is the correct MAOP, 90 was entered in error. Tim Pearson confirmed this by phone.

Records of weekly odor tests conducted by the operator prior to the incident and subsequent tests conducted by the operator immediately after the incident were reviewed by Staff and indicated that the gas was odorized to sufficient levels meeting requirements of 49 CFR 192.625.

Examination of the gas meter and service regulator could not be performed by Staff due to the fact that they were destroyed as a result of the incident.

Operator personnel disconnected the service line at the gas main so that a pressure drop test could be applied from that point to the meter valve. The above ground portion of the service line riser and meter valve had apparently been subjected to extreme heat for a period of time during the fire. The Regulator had partially melted, therefore, operator personnel removed it and installed a plug on the outlet side of the valve. The first pressure drop test showed a small leak. Operator personnel determined the plastic pipe inside the metal riser assembly melted due to the heat exposure to the riser assembly during the fire.(The leakage was found by the operator personnel in the riser assembly, which was located outside the structure and above ground) The riser assembly was then dug up and cut out by the operator personnel; a cap was then installed on the service line just prior to the riser where the service line had not been exposed to extreme heat. A second pressure test was performed by the operator personnel and no leakage was found.

Findings:

The Carrollton fire department report, see _Attachment A, stated that the cause was undetermined due to the structure not being safe to enter. The Carrollton fire department report also stated that a bulge in the floor of the structure indicated that the origin of the explosion occurred In the basement. Staff contacted fire chief Terrell by phone a few weeks after the incident and he revealed that the insurance company holding the policy on the structure had decided not to perform any further investigation of this incident. The house has since been demolished and construction began on a new one Staff found that the operator failed to submit Department of Transportation Form RSPA F 7100.1: Incident Report Form within 30 days after its detection of the incident per pipeline safety regulation 49 CFR 191.9(a). Staff found no other probable violations of Federal pipeline safety regulations.

CFD was Dispatched to 1104 lltb Street in Carrollton, Ky. in reference to house collapse/explosion and fire. A carroll county EMS crew was returinlng from a transport and witnessed the explosion and notified dispatch. Upon arrival of unit 200 the entire northern half of the house vas leveled, fire was blowing out back (west) or C side of the home you could hear the natural gas flowing but could not acceaa the .eter and valve due to the heat and fire coming from the basement of the home. The home owner advised everyone was out at this time. E-205 caught the hydrant as they arrived on scene end laid a S" supply line and began deploying attack linea. Unit 250 requested carrollton Utilitiea to assist in shutting of the gas feed. Heavy black smoke wae filling the entire scene at this time. First attack line vas to the gas meter area in the back of the house. the second line was to the home on the D aide to protect that exposure. l~ supply linea and ground monitora were aet up on both aidea of the stru~ture and a ~ l/2" ·handline waa established at the front of the bouse. All unita were adviaed to use care and until the gaa feed vaa shut down. Unit 250 requested Kentucky Utilities to aaaist ia abutting down electrical linea coming to the scene. He alae requested Ghent Fire Protection Diet. for assistance in fire control and =anpower. Advised to have thea come in fr~ Tilley Dr. and access the C aide of the structure. Once the gas was shut off 250 requested dispatch to contact the State Fire Marshalls Office to send a representative to this scene. R. Allen arrived shortly after we had tbe scene under control and we begBD trying to put out the bot spots and determine the cause of the fire and explosion. Utilities aaaiated with their backhoe in removing debris aad exposing the floor which showed a bulge in the center and the corners indicating the origin was in the baaament. The structure ia too unstable to make entry into the basement at this time &ad conduce a thorough investigation. He queationed the home owner as to what he saw, heard, etc . just before the incident and aa to waht was in the basement of tbe home. He advised tbe furnace, hot water heater, and a fire place in the basement were all supplied by natural gas. He also stated he had been working on hia water softener in the base•ent earlier in the day and had abut off the city water supply to the house and bleed off the pressure in preperatlon of making repairs. When asked, he advised that he didn't smell any odo~a or notice any other problema prior to tbe incident. His mother, who waa sitting on the front porch at the time of the explosion stated that ahe did not smell or notice anything unusual prior to this either. The cause of this is still undetermined due to structure not being aafe to enter the basement and check theae scurcea. CFD will work with the 1aaurance company and their investigators and determine if they want start to demo tba home, to the point of making it aafe enough to enter and determine the actual point of origin and the actual cauae. There ia no suspicion of any illegal acta or improper storage of materials contribuiting to thia incident at thia time. Alae the hone to the North (D Side of Fire Structure) received minor damage to soma of ita

vinyl aiding and craked a couple of windowa due to the beat expoaure but it did nat receive any fire damage. The Clark•a who awn the ather house were not at home at the time of thla incidez:at.
