Safety is paramount to National Grid. In the spring of 2019, we will begin the replacement of a recently installed 16-inch gas main in Merrick, New York. This project, known as the Merrick Reinforcement Project, will help improve safety and overall reliability, and provide Long Island’s gas system with greater operational flexibility, allowing us to meet growing customer demand and support economic growth.

In 2017 and 2018, we substantially completed the installation phase of a new 16-inch underground gas main in Merrick. This gas main had not been placed in service, and thus it did not contain natural gas. During this phase, one of the company’s contractors ran a cleaning tool through the main, causing damage to the interior of the newly installed main. A subsequent evaluation of the interior of the main determined that it was damaged and its integrity was compromised and failed to meet National Grid standards for safety and reliability. As a result, we will need to replace the entire length of the gas main.

We are committed to making every effort to keep neighbors informed and minimize inconvenience and disruptions to the greatest extent possible. That’s why we’ve launched a full-scale community outreach effort, including a community outreach team on site regularly to meet with neighbors and respond to questions and concerns.
