History of ReDig 2004-2007 Program (Legacy KSE)
Localized initiative (LI/NYC/NE)
Region specific – inconsistent work scope design and application, varied regional results
Limited and inconsistent sample sizes – 30 to 55 sites per region
Limited audit/inspection period – 5 to 10 days in duration
Excavation and inspections conducted by outside entity
Corrective Action – localized successes, variable impact, inconsistent follow-up action
Overall lack of enterprise wide standardization
4
2008/Post Merger
Enterprise wide initiative – expanded to include UNY/DNY/NE
Enhanced sampling plan:Driven by volume of work and crews
DNY – 200 inspections
New England – 200 inspections
UNY – 150 inspections
Documented and standardized procedure involving site selection
Excavation activities remain contracted
2009 - QA/QC assumed inspection responsibilities
5
2008/Post Merger Involved Processes
New main and service installation
Replacement main and service installation
Corrosion
Leak repair
Audit/Inspection PeriodExpanded – 12 to 16 weeks
Larger volume of work for inspection
Enhanced validation of compliance findings
Standardized – Metrics, data collection, analysis, reporting and corrective action plan

ReDig Template Development Process

Template Development
Standardized inspection template developed through “Cross-Regional” review process and deployed within all regions
Inspection questions developed in relation to specific processes, procedural steps and requirements
Corresponding guidance notes developed to assist QA/QC inspector
All inspection questions were weighted for the purpose of correctly analyzing/identifying actual degree of risk

Summary 2008
Two regions exhibited risk of non-compliance in excess of 10%
Regulators met with Company Leadership to review program findings and expressed concern related to identified performance.
2009 - 2012 Overall company performance improved each year
Inherent risk in 2012 was below 4%
2013 Company goal is to realize potential risk of non-compliance at a
level of 2.5% or less
