The National Pipeline Mapping System (NPMS) does not contain maps for ecological USAs in Pennsylvania. Are operators responsible for identifying USAs in Pennsylvania?
Yes. Operators are responsible for having identified all pipeline segments that could impact HCAs in all states in which they operate, regardless of whether all of the HCAs have been mapped on NPMS. In those situations where USA maps are not available on NPMS, operators may use ecological and drinking water information used to prepare and maintain their spill response plans, as well as other resources from local and state agencies available to them to identify these USAs.
