"Distribution Integrity Management" (also known as "DIMP") is a regulation of the U.S. Department of Transportation’s (DOT’s) Pipeline and Hazardous Materials Safety Administration (PHMSA).  A final rule was released in December 2009.

NGA and the Southern Gas Association (SGA) announced the development of a joint collaborative to develop a framework document which would provide a foundation and the guidelines for a distribution integrity management plan. The partnership is based on a similar arrangement that the two organizations used in the past for the successful development of a joint Transmission Integrity Management Plan. Structural Integrity (SI) was selected as the contractor to develop the document under the direction of the collaborative.

The document is available for purchase now. More information on purchasing the document is available on the SGA web site:
