Southwest Gas has developed its transmission integrity management program (TRIMP) to comply with the requirements of the U.S. Department of Transportation regulation §49 CFR Part 192, Subpart O – Gas Transmission Pipeline Integrity Management. This comprehensive program has been designed to ensure the integrity of gas transmission pipelines.

The program addresses pipelines located in areas where people gather, called high consequence areas (HCAs). Pipelines within HCAs are inspected beyond normal levels of operations and maintenance. These inspections, called assessments, are repeated on a regular interval, for an increased level of proactive awareness and maintenance.
