What mechanism is available for questioning or challenging HCA and USA identification once such identification has been posted on the National Pipeline Mapping System?
HCAs and USAs have been defined in Part 195. These definitions were developed after considering significant public and industry input, and they are now final. PHMSA Pipeline Safety is using recognized organizations and data sources for mapping HCA information. Anyone having new information that they believe could affect the accuracy of the mapped HCAs (e.g., errors in data sources, or more recent data) should contact PHMSA Pipeline Safety.
