Notice to Pipeline Operators: Update to T4 Shapefile Requirements

In response to Pipeline and Hazardous Materials Safety Administration’s rule amendments to 49 Code of Federal Regulations Part 192, regarding Transportation of Natural and Other Gas By Pipeline, all T4 shapefiles with NGG (Natural Gas Gathering) lines will be required to include several new attribute fields. The Railroad Commission of Texas (RRC) has launched a new internal GIS toolbar to validate these new attributes at the end of January 2024. After this date, any shapefiles submitted to the RRC missing the new required attribute fields will be rejected.

The RRC will be holding an educational webinar in early January 2024 to review the new shapefile requirements.

Shapefiles for NGG lines will require seven additional attribute fields to be included, which will be outlined in the updated guide to shapefile submissions.
