Suit in works over National Grid methane gas leaks
commonwealthbeacon.org
The Conservation Law Foundation said its lawsuit will be based on data submitted by National Grid to state regulators and the foundation’s own field work testing methane levels in the Boston area.

Over a seven-day period in July, the foundation said it identified 15 locations where methane gas concentrations posed the risk of fire or explosion.

CLF found more than 200 public shade trees dead or dying from methane poisoning from leaking gas pipelines.

“National Grid’s leak data shows it allows hazardous Grade 1 leaks to continue leaking for more than 2 ½ years.”
