Distribution Integrity Management Program (DIMP)

Intermountain Gas Company routinely evaluates and prioritizes risks to validate the integrity of the distribution gas pipelines so they continue to be operated in a safe and responsible manner without interruptions.

In order to keep up with state and federal laws, IGC has identified sections of pipe for replacements based on physical and operation & maintenance components.

These type of replacement projects are not new, since 2020 IGC has successfully replaced sections of main and services in the following cities.

Main (LF.) Services (EA)
2020 St. Anthony 29832 305
2021 St. Anthony 33789 350
2022 St. Anthony 20299 170
Sugar City 14991 234
2023 Parker 15500 108
Boise 19300 201
