NGA/SGA DIMP Template and User Guide

Client

Process

• Data inventory• Use selected subset of data• Run through entire data-centric risk

assessment process• Jointly review results of analysis

– Does it feel right?• Recommendations for improvement• Develop project plan • Implementation schedule

Implementation Flowchart

Carve up data by Regions and Zones

Organize and prepdata for analysis

Generate COF,FOF1, & FOF2

Generate ScaledFOF1 & COF and Risk

Selection of Regions

• Define by operator– Areas of responsibility– State reporting requirements

• Size– Too small, poor results– Too large, not actionable

• Begin with the End in Mind– Targeting mitigation

• Data considerations – Availability – Granularity

Data

• Leak data• Facility data• Operational Data• Spatial• SME

Leak Data

• Selected only leaks in pilot study area

• Did not use AGN (Above Ground Nonhazardous) or unclassified leaks

• Totals leak records– 42 for 2009– 27 for 2008– 29 for 2007

Leak Data – Existing Categories

• Test Location – Meter Loop– Svc Line

Upstream of meter

– Svc Line Downstream of meter

– Main

• Type of System– Steel– Plastic

• Leak Type– Corrosion– Natural Forces– Excavation– Outside Force

Damage– Materials & Welds– Equipment and

Operations– Other– Above ground

nonhazardous (AGN)

• System That Failed– Pipe– Valve– Fitting– Drip– Regulator– Tap– Other

Leak Data

• Leak Points– Used address on leak record to resolve location

discrepancies– Fill in missing x,y or adjust

Facility Data• Mains• Service pipe• Regulator Stations• Town Border Stations• Fittings• EFVs• Regulator Station Data• Meter Locations

Facility Data

• Gas Service Pipe– Set Nominal (Operating) Pressure– Set Nominal Diameter to 1” where not set

• EFVs– 13 in the data

• Meters– 5,600 in pilot study area– Locations set during 2009 project

Operational Data

• Gas Main– Set Nominal (Operating)

Pressure • Added field and set value• Received guidance from Cleint• Used Upstream and

Downstream values on RegStations

– Also updated Diameter and Operating Status

Spatial Data

• Publically Available– Streets, parcels, buildings,

township/range/section, environmental, and census data from County

• Updates– Census data (divided total

pop by area to arrive at population/sq. mi.)

• Background data from ArcGIS (online) Map Services

SME Data

• Wall-to-wall paving• Business districts• Seasonal frost cap

Results

Lessons Learned

• Assess data readiness early• Make it a project/manage the process

– Begin with the end in mind– Leverage existing processes and procedures

• Use an industry standard approach• Implement a flexible solution

– Open architecture - No “black box”• “Show your work”• Provide tools to help entire DIM program• Leverage critical GIS Analyst expertise• Drive specific mitigation options
