Why are master meter and LPG system operators proposed to be subject to different requirements?
These systems are generally small, and cover limited geographic areas. The operators often have more direct control over excavation in the area in which they operate, providing more positive control over what is the greatest risk to a distribution pipeline system. These systems are also simpler, usually involving only pipe, meters, and service regulators. There have been few significant accidents on master meter and LPG distribution systems. This justifies a reduced set of integrity management requirements. PHMSA is interested in public comment regarding whether these limited requirements are appropriate or if further limitations should be made. PHMSA specifically seeks public comment on whether these integrity management limitations are appropriate for master meter and LPG system operators; whether we should further limit the integrity management requirements for these operators; or whether we should exempt these operators from integrity management requirements.
