Dominion’s management cultivates a culture of integrity management in order to align itself with the spirit of the regulation.
Dominion has created an Integrity Management Program (IMP) that it believes meets or exceeds the intent of the integrity management regulations. The IMP will be continually refined. Conformance to the processes required by Dominion’s IMP is thoroughly documented and communicated throughout the organization.
For more information, see DOT’s Integrity Management Fact Sheet.
Dominion’s pipeline integrity management program addresses all of the components required by the DOT including, but not limited, to the following components:
High-Consequence Areas (HCAs)
The integrity management regulation was designed to address areas of a pipeline that are located in high-consequence areas (HCAs).
Threat Identification/Risk Assessment
Dominion has adopted a threat-based methodology for managing pipeline risk.
Baseline/Continuous Assessment Plans
Risk assessment provides a rational and consistent method to assess the integrity of a pipeline segment. This method allows for prioritization, which more effectively uses resources in both identifying and mitigating threats.
Remediation is defined as action taken by the operator to mitigate the danger of a potential integrity concern. Remediation includes pressure reduction and/or timely repair and preventive measures that halt a potential integrity problem so it does not proceed to failure.
The company maintains a complete history of all major integrity components within integrated databases.
Performance and Quality Assurance
The company's Integrity Management Program is evaluated to ensure that the program effectively assesses integrity and protects high-consequence areas. A Quality Assurance Plan provides documented proof that the operator meets all requirements of its Integrity Management Plan.
Management of Change
Management of change procedures identify changes to pipeline systems and consider the impact of those changes on the integrity of the pipeline.
Dominion has developed and implemented a communications plan to inform company personnel, jurisdictional authorities and the public about its integrity management efforts and the results of its integrity management activities.
