Columbia Gas plea follows an agreement to pay a $53 million federal fine for blasts and fires north of Boston that killed one man.

With 95% of gas meters relit as of Dec. 5, Columbia Gas of Massachusetts appears to be on track to meet its self-imposed deadline to restore natural gas service to Massachusetts in the wake of a series of massive gas explosions. 

While 45-miles of natural gas pipeline affected by a Sept. 13 gas explosion will be replaced nearly three weeks early, the restoration of full gas service will be delayed by about a month.
