Important Definitions


A “facility” is any structure that is constructed or placed on or in the right-of-way or across the pipeline, such as a concrete slab, concrete conduit, retaining wall or chain link fence, highway, public or private road, railway, ditch, drain/drainage system, sewer, dike, buried and overhead cable, or pipeline.

Ground Disturbance:

A “ground disturbance” means any work, operation or activity on or under the existing surface resulting in a disturbance or displacement of the soil or ground cover.  Ground disturbances can include, but are not limited to, digging, excavation, trenching, ditching, tunneling, boring/drilling/pushing, augering, topsoil stripping, land levelling/grading, plowing, tree planting, land clearing and stump removal, subsoiling, blasting/use of explosives, quarrying, grinding and milling of asphalt/concrete, seismic exploration, driving fence posts, bars, rods, pins, anchors, or pilings, and crossing of buried pipelines or other underground infrastructure by heavy loads off the travelled portion of a public roadway.

Ground disturbance does not include activity to a depth less than 30 centimetres, and agricultural cultivation to a depth less than 45 centimetres that does not reduce ground cover.

Agricultural Activities:

Agricultural Activity is defined as operations which specifically support the cultivation and harvesting of crops on agricultural lands.  This includes the preparation of soil beds to facilitate seeding to a depth of 450 mm (18”) without the removal of cover.  Agricultural activity excludes the use of industrial, heavy, equipment specifically designed for bulk movement of soil.  Generally, equipment employing steel tracks and having implements engineered for excavation (buckets, blades, teeth) are not considered equipment which directly support agricultural activity.
