Historical Highlights
Grade 3 Leak Reduction in New Hampshire
The Liberty NH team has proactively reduced the inventory
backlog of 980 Grade 3 system gas leaks beginning in 2013 and
steadily reduced it to an annual inventory backlog average of 88
leaks over the last three years an overall reduction of 892 Grade
3 Leaks. The drivers of the reductions are listed below:
•	Improvement of the leak management process, evaluating
each leak location and eliminating duplicate recordings of the
leaks.
•	Changes to the NH PUC 500 rules for classification of gas
leaks, a substantial number of the Grade 3 leak backlog was
reduced through the repair of leaks that would be reclassified
to a Grade 2 during 2014 and 2015 and requiring repair.
•	A fair number of Grade 3 leaks were eliminated on leak prone
pipe through the CIBS capital pipe replacement program.
•	Regularly repair Grade 3 leaks on streets where
municipalities are performing pavement overlaying of their
streets.
