AER ST76: the Alberta Pipeline System
ST76 is the Alberta Energy Regulator's licensed pipeline dataset. Township Canada renders every segment as a map layer and lists the lines crossing any parcel.
What ST76 is
ST76 is the Alberta Energy Regulator's Pipeline System dataset: the licensed pipeline network of the province, segment by segment. It is what you need to answer "what crosses this quarter, what does it carry, and how dangerous is it?" Township Canada ingests the full line network and refreshes it monthly.
What it carries
Each pipeline segment carries its licence and line number, segment status, the substance it moves, outside diameter, maximum operating pressure, H2S content and release level, pipeline class location, environment, length, and transfer history. The H2S and substance fields are what make ST76 matter for surface work and emergency planning, not just routing.
Coverage and refresh
We carry more than 320,000 licensed pipeline segments across Alberta, refreshed monthly. On a parcel report we compute the exact length of pipe that falls inside the Legal Subdivision, not just whether a line is nearby.

How Township Canada shows it
ST76 powers the AER Pipelines map layer (Energy Bundle), rendered as a line layer with mid-point labels, and the pipeline list on the Energy tab of the parcel report. Each crossing shows its substance, status, pressure, and H2S level.
