PHMSA Notice & Request for Revisions to National Pipeline Mapping System

[Docket No. PHMSA-2014-0092]

PHMSA is seeking comments on proposed changes to the annual collection of information from each operator to the National Pipeline Mapping System Program. The proposed changes to the attributes will require operators to submit additional information to the NPMS for each pipeline segment, including:

  • the MAOP or MOP
  • the predominant pipe grade
  • hoop stress caused by the highest operating pressure during the year as a percentage of SMYS
  • the type of leak detection system used
  • the level of and types of coating on each pipeline segment
  • the pipe joining method
  • the predominant year of original construction (or installation)
  • class location (for gas transmission)
  • integrity management “could affect” status (hazardous liquid and gas transmission)
  • capability to accommodate inline inspection (ILI) tools
  • the year of a pipeline’s last corrosion, dent, crack or “other” ILI inspection, and of the last direct assessment
  • original and most recent hydrostatic test years and pressures
  • location of all gas transmission and hazardous liquid pipelines abandoned after the effective date of this information collection
  • the installation methods of pipe segments that cross bodies of water greater than 100 feet in width
  • Facility Response Plan control number and sequence number for applicable liquid pipeline segments
  • average daily throughput
  • locations of mainline block valves, the type of valves and the type of valve operators
  • locations of storage fields and the field type
  • locations of refineries (for liquid operators) and gas process/treatment plants (for gas transmission operators)
  • breakout tank locations and attributes
  • liquefied natural gas (LNG) plant type, capacity, impoundments, exclusion zones and year constructed
  • locations of pump (for liquid operators) and compressor (for gas transmission operators) stations.

PHMSA also proposed to include offshore gas gathering pipelines in NPMS data submissions, and to require a positional accuracy of five feet for pipeline segments located within Class 3, Class 4, High Consequence Areas (HCA), or “could-affect” HCAs.

PHMSA invites comment on how this expanded collection of information could affect the annual report. Submit written comments on or before September 29, 2014, identified by Docket No. PHMSA–2014– 0092 via the online Federal eRulemaking Portal.
