Incident Command System

TNPI has adopted the Incident Command System (ICS) structure to manage emergencies. ICS is a standardized on-site management system designed to enable effective, efficient incident management.

In the ICS structure, the first person on the scene of an emergency becomes the Initial Incident Commander. Their role is to evaluate the incident, establish an Incident Command Post and assess the need for additional resources including activating the Incident Management Team which may include TNPI employees and third-party contractors as well as emergency responders, government agencies and regulators.

In the unlikely event of an emergency involving a TNPI pipeline, we the Incident Management Team will operate under a Single Command structure or a Unified Command Structure.

Single Command Structure

Under Single Command, there is one Incident Commander. This is typically the case for smaller incidents, involving only TNPI’s facilities and when few, if any regulators or outside agencies are involved. A larger scale incident will commonly transition from Unified Command to Single Command once the initial emergency has past and the company is moving to remediation.

Following is a diagram of the roles within the Incident Command Structure.

Unified Command Structure

Under Unified Command, decisions are made by two or more jurisdictions. For example, TNPI and a regulatory agency. Unified Command is required when incident management requires decisions to be made by more than one jurisdiction. Once joint decisions have been made, one member is identified to speak for the Unified Command Team. In Unified Command, TNPI will assume the role of the Responsible Party (RP), working closely with all agencies to ensure a safe and effective response.
