The National Pipeline Mapping System (NPMS) has issued a new set of guidelines for annual pipeline data submissions. These new guidelines apply to DOT/PHMSA-regulated pipelines, breakout tanks, and LNG facilities.

  • Beginning January 1, 2009, annual NPMS data submissions should be made at the same time as hazardous liquid transmission and gas transmission annual report submissions. The due date for gas transmission reports is March 15 and the due date for hazardous liquid reports is June 15.
  • Data submittals must be accompanied by a transmittal letter, the format of which is detailed in the new guidelines.
  • Beginning December 15, 2008 attribute data and metadata must be revised according to the new guidelines or submittals will be rejected. Changes include a more detailed product description and more specific codes for pipeline changes.
  • Beginning December 15, 2008, abandoned pipelines should only be submitted to NPMS once. Following the first submittal, abandoned pipelines should be removed from all subsequent submittals. If a pipeline has already been submitted as abandoned, it should be removed from the operator’s data before the next annual submittal.
  • NPMS has released an updated version of its attribute and metadata creation software. Any attributes or metadata created with the previous version of the software will be rejected as unacceptable. The new software is available here for download.
  • Digital data submittals are strongly encouraged, as are early submittals.

RCP is highly experienced with NPMS submittals and is fully equipped to update existing NPMS data to meet the new standards or to generate new submittals. For a copy of the new NPMS Guidelines, or for more information, contact Jessica Roger.
