"Each day, thousands of businesses and millions of people rely on the safe, secure, and efficient movement of commodities through the transportation system. Manmade or natural disruptions to this critical system could result in significant harm to the social and economic well-being of the country. The Nation's pipeline system is a mode of transportation with unique infrastructure security characteristics and requirements. As required by Executive Order 13416, the Pipeline Modal Annex implements the Transportation Sector Specific Plan (TSSP) and was developed to ensure the security and resiliency of the pipeline sector. The vision of this plan is to ensure that the pipeline sector is secure, resilient, and able to quickly detect physical and cyber intrusion or attack, mitigate the adverse consequences of an incident, and quickly restore pipeline service. The core of the plan is a pipeline system relative risk assessment and prioritization methodology. This methodology provides a logical prioritization process to systematically list, analyze and sort pipeline systems and critical pipeline components within those pipeline systems. By prioritization, security resources can be effectively used to manage risk mitigation in order to protect critical pipelines from terrorist threats. The methodology is based on the Transportation Sector Systems-Based Risk Management (SBRM) methodology, which is in turn based on the Risk Management Framework presented in the NIPP."
