National Grid reached a settlement with New York state more than two years after a gas explosion destroyed and damaged several Little Falls homes and injured a few people. The explosion happened on February 14, 2018.

The state's Public Service Commission said National Grid is paying $658,000 for actions that may have violated commission regulations. 

The commission said National Grid disputed wrongdoing, but after an investigation, has agreed to enhance its operational, training, and programmatic practices and procedures.

They've modified their gas procedures at all three of their New York service territories, adding a list of substandard conditions to address — that includes documenting and sealing gas pipes at the inside wall penetration if an inside seal is not found.

National Grid has also updated its training of contractors and employees. The commission said both parties have agreed to forego litigation on the issue of the explosion's cause.
