Synopsis: On September 13, 2018, about 4:00 p.m. local time, a series of structure fires and explosions occurred after high-pressure natural gas was released into a low-pressure natural gas distribution system in the northeast region of the Merrimack Valley in the Commonwealth of Massachusetts. The natural gas distribution system was owned and operated by Columbia Gas of Massachusetts, a subsidiary of NiSource, Inc. Columbia Gas of Massachusetts delivers natural gas to about 325,000 customers in Massachusetts. One person was killed and 22 individuals, including three firefighters, were transported to local hospitals due to injuries; seven other firefighters incurred minor injuries. The fires and explosions damaged 131 structures, including at least 5 homes that were destroyed in the city of Lawrence and the towns of Andover and North Andover. Most of the damage occurred from fires ignited by natural gas-fueled appliances; several of the homes were destroyed by natural gas-fueled explosions. Fire departments from the three municipalities were dispatched to the fires and explosions. First responders initiated the Massachusetts fire-mobilization plan and received mutual aid from neighboring districts in Massachusetts, New Hampshire, and Maine. Emergency management officials had the electric utility shut down electrical power in the area, the state police closed local roads, and freight and passenger railroad operations in the area were suspended. Columbia Gas of Massachusetts shut down the low-pressure natural gas distribution system, affecting 10,894 customers, including some outside the area who had their service shut off as a precaution. The National Transportation Safety Board made new recommendations to the Pipeline and Hazardous Materials Safety Administration; the 31 states with an industrial exemption for natural gas infrastructure projects; the Commonwealth of Massachusetts Executive Office of Public Safety and Security; and NiSource, Inc.

Probable Cause: The National Transportation Safety Board determines that the probable cause of the overpressurization of the natural gas distribution system and the resulting fires and explosions was Columbia Gas of Massachusetts’ weak engineering management that did not adequately plan, review, sequence, and oversee the construction project that led to the abandonment of a cast iron main without first relocating regulator sensing lines to the new polyethylene main. Contributing to the accident was a low-pressure natural gas distribution system designed and operated without adequate overpressure protection.

Communication Type: NPRM Response

Communication Contents: The National Transportation Safety Board (NTSB) has reviewed the Pipeline and Hazardous Materials Safety Administration’s (PHMSA) notice of proposed rulemaking (NPRM), titled “Pipeline Safety: Safety of Gas Distribution Pipelines and Other Pipeline Safety Initiatives,” published at 88 Federal Register 61746 on September 7, 2023. The NPRM proposes amendments to Title 49 Code of Federal Regulations (CFR) Parts 191, 192, and 198 in response to congressional mandates in the Leonel Rondon Pipeline Safety Act and an NTSB safety recommendation aimed at preventing catastrophic incidents resulting from overpressurization of low pressure gas distribution systems. The NTSB investigated two natural gas accidents that resulted in recommendations that are applicable to this NPRM. We describe these investigations and offer comments on the following topic areas: Clarifications and Updates to Distribution Integrity Management Program Plans, Updates to Emergency Response Communications, Updates to Operations and Maintenance Procedural Manuals, and Requirements for New Regulator Stations. Related NTSB Investigations In February 2018, the NTSB investigated a natural gas fueled explosion in Dallas, Texas, which resulted in 1 fatality; 4 injuries; a destroyed home; and the evacuation of 300 homes, 250 apartment units, and 600 students. In the 2 days before the explosion, two gas related incidents occurred on the same block at houses that were served by the same natural gas main, each resulting in one injury and significant structural damage. We determined that the probable cause of the accident was the ignition of natural gas that leaked from a gas main that was damaged 23 years earlier and was undetected by the operator’s investigation of the two related incidents that occurred in the 2 days before the explosion. In September 2018, the NTSB investigated the overpressurization of a natural gas distribution system in Merrimack Valley, Massachusetts, which resulted in fires and explosions, 1 fatality, 22 individuals being taken to local hospitals, 5 destroyed homes, 131 damaged structures, and the evacuation of 50,000 residents. We determined that the probable cause of the accident was the operator’s failure to adequately plan, review, sequence, and oversee a pipeline construction project. Updates to Emergency Response Communications NPRM Commentary In the NPRM, PHMSA proposes to expand the existing list of pipeline emergencies in its regulations for which operators must have procedures ensuring prompt and effective response by adding emergencies involving a release of gas that results in a fatality, as well as any other emergency deemed significant by the operator. PHMSA also proposes regulatory amendments requiring operators to update their emergency response plans to improve communications with the public during an emergency. NTSB Comment In our Merrimack Valley investigation, we noted our concerns about the operator’s communications with emergency response officials. We concluded that the operator was not adequately prepared with the resources necessary to assist emergency management services with the response to the accident. As a result, we issued Safety Recommendation P 19 18 to the operator to, in part, review its protocols and training for responding to large-scale emergency events, including providing timely information to emergency responders. After the operator instituted significant changes to enhance its emergency preparedness and response capabilities, we classified the recommendation as Closed—Acceptable Action. The NTSB supports PHMSA’s proposal for operator emergency response communications, and we look forward to the final rule. Summary The NTSB supports many of the NPRM’s proposed revisions to its pipeline safety regulations. However, we believe that the proposal has some shortcomings and encourage PHMSA to address our comments in its final rulemaking. Thank you for the opportunity to comment on this notice.

Communication Contents: -From Joe Hamrock, President & CEO: In February 2019, NiSource significantly enhanced our Gas Segment Emergency Preparedness and Response (EP&R) efforts based on learnings from the Merrimack Valley incident in 2018 and through research and interactions with private and public stakeholders. We built upon our existing efforts and created a full-time, cross-functional EP&R team to integrate improved preparedness plans and exercises covering a broad range of potential scenarios and levels of emergency. The team will also play an important role in significant emergency events, as needed. Through ongoing training that includes regular exercises, the EP&R team provides awareness and understanding of all roles during an emergency to appropriate employees across the NiSource gas segment and corporate support teams. The goal is to ensure an Incident Management Team capable of a timely and effective response to incidents with potentially wide ranges of scale and complexity anywhere in NiSource’s service territory. We also strive to be positioned to assist peer utilities in their restoration efforts as required. In addition, NiSource created a single EP&R Plan that was implemented across the NiSource gas segment beginning on September 1, 2019. As part of a single EP&R Plan, a primary focus is implementing the Incident Command System (ICS) to ensure a clear leadership structure in the event of an incident. This plan provides multiple backups for each role to ensure our ability to support a lengthy incident response and enhances our ability to interact with public safety officials and first responders. The new plan also provides clear guidance for communications to ensure the public and relevant stakeholders are appropriately informed in a timely manner. Since forming the EP&R Plan and team, NiSource has: •?Completed best practice visits externally with gas industry peers and internally with the Northern Indiana Public Service Company’s electric storm team. •?Adopted the ICS as recommended and used by FEMA and other companies and agencies and established a structure with multiple backups for each role. This helps ensure our ability to support sustained incident response and readiness, as having a complete roster with trained backups provides depth in the event an employee with primary responsibility is unavailable. •?Reviewed and analyzed existing corporate and NiSource operating company Emergency and Crisis Communications Plans and Business Continuity Plans, and ensured their alignment with our Emergency Preparedness and Response Plan. •?Outlined consistent definitions for incident levels from less severe (Level 5) to the most severe (Level 1) to align with the American Petroleum Institute’s Recommended Practice 1173, which is industry best practice. •?Mandated annual computer-based training for every NiSource employee – whether directly involved in the ICS or not. •?Developed and began executing on a multi-year training and exercise program to include enhanced training for employees with leadership roles in the Emergency Preparedness and Response Plan and ICS. Training includes computer-based training, instructor-led position-specific coaching sessions and statewide exercises, the first of which was held in September 2019. •?This training and exercise program is part of a comprehensive exercise program overseen by an independent, expert third-party evaluator. The enhanced training builds employee familiarity with the plan and its processes and terminology, while ensuring they more deeply understand their roles and responsibilities. It also emphasizes the importance of strong relationships with external stakeholders. •?Facilitated the successful completion of classroom training and certification in Federal Emergency Management Agency ICS 100, 200, 300, 700 and 800 modules for members of the EP&R team. •?Established a “Go Team” of approximately 20 high-level employees to serve, as needed, for the most severe or catastrophic Level 1 and Level 2 incidents. The team will be utilized at a Level 1 or Level 2 incident in any of our states, if needed, as supplemental resources or backups for all ICS positions. This cross-industry best practice ensures that a small but core group of leadership is ready and trained to engage in a significant incident as soon as possible. In early December, this “Go Team” participated in a tabletop exercise followed by an intensive 21-hour, instructor-led training course: “Federal Emergency Management Agency ICS 300: Intermediate Incident Command System for Expanding Incidents.” •?Ordered four custom-built Mobile Command Centers that will strengthen our ability to efficiently, effectively and safely respond to incidents, while also supporting training exercises across our service territory. Each 38-foot trailer will be strategically located in NiSource locations to allow for rapid deployment and the least amount of travel time. Delivery is expected in early 2020. In addition to direct contact between the company’s Incident Commander and the applicable public safety Incident Commander, the ICS ensures strong communication and collaboration with all major emergency responders through liaisons, public information and on-site personnel. Our training and exercise plan is robust but in its early stages. Our plan relies on a continuous, multi-year framework of steady training and exercises. We have more to do, and will continue to develop and enhance our abilities moving forward. For example, in the first quarter of 2020, we will conduct tabletop exercises in each state in which we operate to assess our performance when responding to Level 3 to 5 incidents. During the third quarter of 2020, we expect to conduct at least one exercise to test our performance against the plan when responding to Level 1 to 2 incidents. This functional exercise will bring together employees from across NiSource and will simulate a major incident, including interaction with external stakeholders. Later in the year, our “Go Team” members will continue their advanced incident command training by participating in “FEMA ICS 400: Advanced Incident Command for Complex Incidents,” a 15-hour, instructor-led course that focuses on area command and multi-agency coordination to support effective incident response. A Level 1 or Level 2 multi-state, full-scale exercise is planned for the second quarter of 2021 with widespread participation from internal functions and external partners. (The Homeland Security Exercise and Evaluation Program serves as the foundation and framework for NiSource’s exercise program management.) Lastly, NiSource is enhancing its corporate crisis response efforts. These efforts include updated response protocols, including external communications assignments and materials for use during crisis situations. NiSource is incorporating these materials into the Gas Segment Emergency Preparedness and Response plan. We appreciate your interest in our emergency preparedness and response updates, and are confident that the improvements we have made have enhanced overall pipeline safety across our seven states. Though there is still work to do, NiSource is making solid progress on the issues outlined in the recommendation. As always, a commitment to safety and continuous improvement remains our top priority. We continue to welcome your feedback about our response to this recommendation.

Communication Contents: -From Joe Hamrock, President and CEO: NiSource instituted a suite of changes to improve our response to emergency events. Our dedicated team of Emergency Preparedness & Response (EP&R) experts identified nearly 1,000 employees for roles in the Incident Command System (ICS), launched a multi-year training and exercise program, and staffed a “Go Team” for rapid response to high-severity incidents. We continue to build upon this solid foundation in 2020 and plan to continue in the years ahead. The consulting firm Nixon & Associates continues to provide benchmarking and independent analysis related to our ongoing training and exercise program. Nixon & Associates is an emergency planning and crisis response firm based outside Washington, D.C., with more than 25 years of experience in the energy, utility, and chemical industries. The firm will remain a key partner in future exercises to identify and implement improvements to our emergency preparedness and response capabilities. Tabletop Exercises In late February and early March 2020, in-person tabletop exercises were conducted for Columbia Gas companies in Virginia, Ohio, Massachusetts and Kentucky. Due to the COVID-19 pandemic, in-person exercises for Columbia Gas of Pennsylvania/Maryland and Northern Indiana Public Service Company (NIPSCO) were postponed and conducted virtually via the webcasting platform WebEx in June and July, respectively. These exercises were designed to assess our performance when responding to Level 3 to 5 incidents and highlighted the increased capabilities of the organization, as well as areas of improvement, and were conducted while the ICS was active for our COVID-19 response. Nixon & Associates has provided an independent evaluation of the exercises, and those findings are being incorporated into our Emergency Preparedness and Response plans. COVID-19 Response The COVID-19 pandemic presented numerous challenges for NiSource and its Columbia Gas and NIPSCO subsidiaries. In addition to the safety, health, and operational concerns stemming from this situation, COVID-19 provided the first opportunity to implement a comprehensive, NiSource-wide response that incorporated lessons learned following the 2018 Merrimack Valley incident and the after-action reviews of incidents and exercises. The company activated plans and personnel across its seven-state footprint at the local, state, and corporate levels. The pandemic response is being managed by the ICS, and an Area Command was established to provide strategic guidance to Incident Management Teams (IMTs) in each state. These teams have responsibility for local execution of response objectives. The pandemic is impacting every aspect of our business, at every level of the organization, with more than 300 employees being activated for ICS roles in supporting the company’s COVID-19 response. Through its response to the pandemic, the company has expanded its foundational ICS knowledge and capabilities beyond the gas segment to utilize the ICS framework to guide a NiSource-wide response. The response emphasized common terminology, consistent processes, appropriate safety protocols, and strong communications. To date, the company has avoided a widespread outbreak of COVID-19 among its employees while experiencing no reported employee-to-customer or customer-to-employee transmission through hundreds of thousands of necessary interactions during the pandemic. In response to COVID-19, we engaged in a comprehensive, extended, multi-company utilization of both the ICS and the Area Command System. We achieved positive results, enhanced our engagement with local emergency management teams, and identified additional opportunities to learn and improve. NiSource conducted an after-action review of the initial phase of the COVID-19 response. Based on feedback from hundreds of employees involved in the response, opportunities were identified regarding communication, process improvement and development, and clarity of ICS roles and responsibilities. The Area Command prioritized four findings from the after-action review and input those findings into the risk management Corrective Action Program (CAP) tool within our Safety Management System. Similar to the tabletop exercises, Nixon & Associates provided an independent evaluation of the company’s initial COVID-19 response. Lessons learned from internal reviews and the Nixon & Associates evaluation are being incorporated into EP&R continuous improvement plans. Functional Exercise On August 25, 2020, NiSource conducted a Multi-State Functional Exercise from the NIPSCO local operating area in Monticello, Indiana, with cross-functional and multi-jurisdictional participation from across NiSource and police, fire, EMS, and emergency management officials. Because of COVID-19, this exercise was mainly virtual, with some members of the IMT on site in Indiana. More than 100 individuals with ICS roles from across NiSource participated. Additional participation came from multiple evaluators and hundreds of observers from both inside and outside the company. The Functional Exercise tested our performance against the plan when responding to Level 1 to 2 incidents in a semi-virtual environment. As part of our enhanced rapid response capabilities, the NIPSCO Gas IMT deployed and utilized one of the recently acquired, custom-built Mobile Command Centers during the exercise. These 38-foot trailers strengthen our ability to efficiently, effectively, and safely respond to incidents, while supporting similar training exercises across our service territory. Four of them will be situated throughout our seven-state footprint and bring a functionality we did not previously possess. The Functional Exercise tested response capabilities and simulated a major incident with increasing scope and complexity involving severe weather, gas and electric infrastructure impacts, technology challenges, cybersecurity, and terrorism. Throughout the day, the Functional Exercise required participants to take action, make decisions, simulate personnel activation and resource deployment, and respond to new developments. IMTs representing NIPSCO Gas (with support from across NiSource), NIPSCO Electric, NiSource Information Technology, White County, Indiana, Public Safety, and Carroll County, Indiana, Public Safety, exercised plans, policies and procedures and developed objectives and tactics to oversee and guide the response to the scenario. Evaluators provided feedback on IMT performance, including strengths and opportunities for improvement. Nixon & Associates reviewed this exercise. Training To date, building ICS knowledge, including roles, responsibilities, and key principles, has been the emphasis of the training and exercise program. Computer-based training was assigned to all NiSource employees in 2019, with more specific training provided to more than 1,000 employees with a role in the company’s ICS. The company is also expanding its training to include those beyond the Command and General Staff. For example, in late June, a Supporting Staff Self-Study Workbook was distributed to all NiSource employees with an Incident Command System role. This interactive workbook educates employees about ICS principles, provides real world scenarios, and emphasizes the company’s philosophy about preparedness and response. The EP&R team is working closely with its technical training and instructional design groups to build additional training materials for those ICS roles that do not link to existing positions within the company. In Q4 2020, we will begin deploying a series of computer-based modules to our front-line employees who may serve as first responders during incidents to strengthen their ICS knowledge and capabilities. As previously disclosed, in 2019 NiSource established a “Go Team” of approximately 20 high level employees to serve, as needed, for the most severe or catastrophi
