Good afternoon. I'm seeking experts in U.S. natural gas infrastructure, safety, environmental regulation, and other relevant fields to share insights for a story looking at the continued need to modernize the country's 50+ year old pipes and related distribution equipment. I'm also interested in hearing from U.S. residents who have dealt with a natural gas leak in their home or business and how that was handled. My main questions are: 1) PHMSA reports that some cast iron and bare steel natural gas pipelines remain in service, many installed more than 60 years ago. What risks do aging materials pose today, and how urgent is the need for replacement? 2) A national estimate found roughly 630,000 leaks across U.S. natural gas distribution mains. How much of that problem is attributable to aging infrastructure, and which technologies or investments could have the biggest impact on reducing leak rates? 3) The federal government recently allocated nearly $200 million for pipeline modernization projects due to safety, reliability, and methane leakage concerns. Does this level of investment reflect the true scale of the infrastructure challenge, or is there still a significant funding gap? 4) Researchers have linked older cast iron and bare steel pipelines to higher leak rates, safety concerns, and methane emissions. What do you see as the long-term economic and operational costs of postponing upgrades? 5) Natural gas remains a major source of electricity generation and home heating in the United States. How well is existing infrastructure positioned to meet future demand, especially during extreme weather events and peak-use periods? Thank you for your time and consideration.
