The town has confirmed that there are 148 gas technicians in North Andover working on restoring service to the non-impacted areas. They have visited 405 of the 1606 properties in this category as of 4:30pm. They will be working late into the night to visit all 1606 properties. If they have been to your house and you were not home, they should have left a door hanger with a number to call. Call that number right away since they may be able to return later this evening.
