To ensure that the citizens of Arizona have railroad and pipeline systems that are operated and maintained in as safe a manner as possible.
The Arizona Corporation Commission's (ACC) Office of Pipeline Safety (AZOPS) is an integral part of the Safety Division. The AZOPS has the responsibility to inspect and enforce safety regulations on all intrastate pipeline operators and by way of agreement, act as an agent for the Pipeline and Hazardous Materials Safety Administration (PHMSA) for inspection of all interstate pipelines operating within the State of Arizona. For more information on PHMSA's role in pipeline safety, they maintain a very helpful website with links to pertinent regulations and detailed information about its offices and responsibilities.
The website can be viewed at http://www.phmsa.dot.gov/pipeline.
The Commission has jurisdiction over matters pertaining to public rail and highway crossings.
