Distribution Integrity Management Rule - Compliance Framework Document

  • This project was completed in February 2010 and is a joint project with the Northeast Gas Association.
  • Scope:
    • The framework document serves as an outline for distribution companies to build customized distribution integrity management plans that comply with the final rule. The supporting documents, templates and tables have been included in a “user’s guide” that support the framework document.
    • This framework document and user’s guide was developed to provide distribution operators with a document that could be customized to meet the specific needs of large and complex systems as well as smaller systems. Members of the collaborative have operations ranging from those that serve more than 3 million customers and cover multiple states and jurisdictions to those that serve less than 50,000 customers.
  • Twenty SGA member companies and 25 Northeast Gas Association member companies participated in this project.
