starts Oct 19
Merger & Acquisition Activity Status
National Grid was sold to Liberty Utilities (CAN)
NG announced looking to exit New Hampshire in 2010
Gas & Electric Divisions Settlement approved
through Commission Order
Safety Requirements were memorialized
Performance Metrics were attached
Newest Operators Paper Mill in Coos County was added and tapped
off an interstate pipeline with a new gate station.
Landfill Operator also added to feed the same Paper Mill
Seen an increase in single on site LNG systems in the State (non regulated)
Seen a consolidation of LP companies within the industry and effects are beginning to occur in NH as well.
NH Pipeline Safety Rule Update
Existing Rules every 10 years
Have met with Nat Gas Operators
Have met with LP Operators
Exchanged Information with Landfill Operators
Oct 19 Public Hearing on initial proposal
Expected to be completed January 2013
NH Pipeline Safety Rule Update
Uniform Leak Grading System Memorialized
Modified when emergency notifications need to occur
Prohibit new master meter systems Welding Qualification Intervals with
Destructive Tests are defined
NH Pipeline Safety Rule Update
Regulators on Risers and Meter Sets will be in alignment with NFPA 54 distances
Specified periods for system odor checks and locations
Construction Quality Assurance Plans are required
LPG Operators will be required to use an odorometer more measuring at the bulk tank storage with sniff tests during any maintenance activities
and more………

2008-2012 Accelerated Cast Iron Bare Steel Replacement Program
National Grid Applies to internally driven projects not
externally driven 5th year of program Increased from $300 k/yr to $3 million/yr Customized program specific to NH Approximately 3 to 4 miles per year are removed
internally driven and 3 to 4 miles per year externally driven
Extensive review of all aspects of program by regulators
2008-2012 Nat Grid Accelerated Cast Iron Bare Steel Replacement
Program Starting point 135 miles CI, 17 miles BS in NH Replaced approximately 27 miles over last 4 years Bare Steel Services are replaced at rate of
approximately 250 per year. Existing Rate will take approximately 18 years to
complete
2008-2012 Nat Grid Accelerated Cast Iron Bare Steel Replacement
Program Regulator Involvement
Annual approval of prioritization list and amount to be replaced and line item costs per segment are submitted
Each bare steel section, catalogued, photographed and tested for remaining wall thickness and level of corrosion
Report Generated on all Bare Steel Sections Cut outs of Pipe Replaced are submitted to NHPUC Inspection priorities are centered around CIBS for constant field
monitoring. Extensive review of costs to remove items that are not related to
defined parameters Testimony at annual docketed hearing on cost recovery and
program impact
2008-2012 Nat Grid Accelerated Cast Iron Bare Steel Replacement
Program Program Benefits:
Worst Leak Prone Pipes are targeted based on
leak/main break history, material, age, Field Input
Approximately 250 Bare Steel Services per year are replaced that normally would not
More Meters are moved from inside to outdoors Proactive vs Reactive Mentality
