View Rule

The Commission proposed to amend the filing requirements for natural gas pipeline system maps. Under current regulations, natural gas pipelines must include a system map as part of their tariff on file with the Commission, and file an updated map by the following April for any year that there is a major change in the pipeline's system. Additionally, this map must be posted on the pipeline's own website. In order to reduce regulatory burden on these pipelines, the Commission proposed to eliminate the requirement to file a map as part of the tariff, leaving only the requirement to maintain a map on the pipeline's own website. Furthermore, in order to promote transparency, the Commission proposed to change the deadline for updating system maps. Currently, if a pipeline experiences a major change that renders its existing map obsolete, it must make a tariff filing no later than April 30 of the subsequent calendar year. The Commission proposed a quarterly deadline for updating pipeline maps (Docket No. RM14-21-000).
