What We Know
American Gas Foundation (AGF) Study
•Independent report: Safety Performance and Integrity of the Natural Gas Distribution Infrastructure
•Included State Regulators and Utility Operators
•Incidents analyzed over a 12 year period (1990 – 2002)
![Page 4: D AMAGE P REVENTION : A RE THE S TATES AS E NGAGED AS T HEY N EED TO B E ? C HRISTINA S AMES V ICE P RESIDENT O PERATIONS & E NGINEERING A MERICAN G AS.](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcb68f/html5/thumbnails/4.jpg)
AGF Findings
•On distribution lines, outside force is
–60% of incidents
–Nearly 50% of all serious incidents
•3rd party damage accounts for nearly 75% of the serious outside force damage incidents

Distribution Integrity Management Program (DIMP)
EDP Team included:
–PHMSA
–Distribution utilities
–State pipeline safety representatives
–Contractors
–Common Ground Alliance

DIMP EDP Focus
•What actions, approaches or practices can be applied to reduce excavation damage?
•How do states with/without comprehensive damage prevention programs and effective enforcement compare?
![Page 10: D AMAGE P REVENTION : A RE THE S TATES AS E NGAGED AS T HEY N EED TO B E ? C HRISTINA S AMES V ICE P RESIDENT O PERATIONS & E NGINEERING A MERICAN G AS.](https://reader036.fdocuments.us/reader036/viewer/2022062719/56649ec05503460f94bcb68f/html5/thumbnails/10.jpg)
Findings
•Excavation damage is declining but still presents the greatest threat to distribution pipeline safety.
•EDP poses the greatest opportunity for safety improvements.
•Distribution pipeline safety and EDP are intrinsically linked. EDP must be addressed to improve pipeline safety.

State Specific Findings
•States with comprehensive EDP programs that include effective enforcement have a substantially lower risk of excavation damage to pipelines and related consequences.
•Federal legislation is needed to help develop and implement comprehensive EDP programs at the state level
•Requires a partnership of all stakeholders

Elements of Effective EDP Program
1. Enhanced communications between operators and excavators
2. Foster support/partnership of all stakeholder3. Operator’s use of performance measures4. Partnership in employee training5. Partnership in public education6. Dispute resolution process7. Fair and consistent enforcement8. Use of technology to improve process9. Data analysis to improve program
effectiveness

What is working
•Reductions in excavation damage in states with:
–Fair and effective enforcement of ALL parties (not just pipeline operators)
–Everyone is involved
–Enhanced communications among all parties
–Partnerships (regional CGAs, partnering with schools, etc)

What doesn’t work
•Not involving all parties
– Everyone must be in the pool
(pull them in if you have to)
•Excavation laws that exempt entities
•Excavation laws with no teeth
•Lopsided enforcement
•Independence
