Interchangeability Implementation Process
1
Understand Historical Supply
2
Identify “Sensitive Receptors”
- LDC’s catalog potential sensitive customer equipment
4
Assessment
- Assess sensitive equipment- Establish extent of retrofits- Negotiate fixes
5
SettlementAgreement
- Establish interchangeability Tariff parameters - Establish most economical retrofit strategy , schedule & cost sharing mechanism
- Work with Pipelines to establish system adjustment
gas
• Work with Pipelines and Suppliers• Establish reasonable supply compositions
Understand “Zone ofInfluence”

Next Steps……….
• Consolidate End Use Data
• Proposal To Have an independent third party “expert”, (GTI), assess the surveys to qualify and quantify real vs perceived impacts
• Study to be funded collaboratively via stake holders from all segments…….
• Results of the study will be made “public” in the best interest of the industry to resolve similar issues
![Page 15: 1 Interchangeability Sensitive Receptor Inventory Algonquin Gas Transmission New England Customer Meeting Robert D. Wilson Director, Environmental Operations](https://reader035.vdocuments.net/reader035/viewer/2022081514/5697c01a1a28abf838ccee9c/html5/thumbnails/15.jpg)

Remaining Challenges……..
• Responsibility of all stake holders in the value chain. Suppliers / Producers, Pipes, LDC’s and End Users need to work together and build on the technical foundation laid by the NGC+ technical teams.
• Realization that many existing tariffs will need to be updated to address interchangeability, hydrocarbon liquid dropout and overall gas quality issues. • Timing is a challenge….. LNG terminals need to know now what design options are necessary to accommodate future tariff requirements.
