What criteria must an operator use in determining whether automatic shut-off valves or remote control valves are required to protect HCAs?
Operators must make these determinations based on their risk analysis and using criteria that they define, considering the circumstances of each. The rule includes specified factors that must be considered in these evaluations. They include: • the swiftness of leak detection and pipeline shutdown capabilities, • the type of gas being transported, • operating pressure, • the rate of potential release, • pipeline profile, • the potential for ignition, • location of nearest response personnel. An operator is required to install an ASV or RCV if the operator determines that it would be an efficient means to protect an HCA in the event of a gas release. OPS inspectors will review operator determinations. • FAQ-90. When must operators implement additional preventive and mitigative measures? For example, how long after completing the baseline assessment for a segment can an operator take to conduct a risk analysis and determine whether additional preventive or mitigative actions are needed (i
