The Gas Piping Technology Committee (GPTC) developed the Distribution Integrity Management Program (DIMP) guidance in anticipation of the Notice of Proposed Rulemaking issued by PHMSA. GPTC has provided guidance for compliance with federal pipeline safety regulations since 1970. The GPTC Guide for Gas Transmission and Distribution Piping Systems was developed by a task group to: follow the 7 key elements of DIMP, address the needs of all operators (including small systems), and provide examples on how to implement the rule.

The DIMP guidance document is open for public review and comment. Comments on the draft guidance must be submitted to the GPTC by the close of business on September 8, 20008.

For a copy of the GPTC draft guidance for DIMP (including comment form), contact Jessica Roger.
