Rationale and scope:

Field inspection in conjunction with the Fisheries and Oceans Canada (DFO) site visit of Spread 2 watercourse crossings for which authorization was issued under the <em>Fisheries Act</em>&nbsp;due to the presence of critical habitat for Athabasca rainbow trout . The primary purpose was to evaluate the integrity of the restored bed and banks of watercourses and ensure appropriate mitigation is in place to prevent sedimentation of the watercourses. An Indigenous Monitor (IM) from the Indigenous Advisory and Monitoring Committee (IAMC) participated in this activity.

This inspection was focused on several watercourse crossings in Spread 2 that provide critical habitat for Athabasca rainbow trout (Endangered). Pipeline crossing and reclamation activities had been completed at all the watercourses observed during this inspection. Erosion and sediment control appeared functional, though some areas requiring maintenance (e.g., removal of accumulated sediment) were observed. The riparian areas had been seeded (grasses) and staked with willows, with varying degrees of growth observed (from ~10-60% coverage) after less than a full growing season.  Trans Mountain representatives indicated that areas with low willow-staking success would be revisited during reclamation activities for the remainder of the RoW and that crews had been provided with additional training on willow staking. At some crossings (e.g, Trail Creek), the area of disturbance was narrowed within the riparian buffer.

In general, appropriate signage was observed (e.g., environmental resources, no fueling). Areas of noxious weeds (e.g., oxeye daisy) were observed in multiple locations along the RoW, as well as in high densities off RoW (e.g., along public roads). Weed management was discussed and Trans Mountain indicated that weed management activities (i.e., spraying) were ongoing and into the second treatment of the summer and the areas noted during the inspection were provided to the appropriate personnel for follow-up.

Observation 2 - Corrected Non-Compliance - Non-Functional Erosion and Sediment Control

Date & time of visit: 2022-07-27 11:00

Discipline: Environmental Protection




Along access road 146, the geotextile wingwalls on a bridge over a watercourse were not functioning as intended due to damage to the geotextile. One side was observed to have a tear near ground level and the other side had a hole through which sediment was deposited within the riparian area of the creek (non fish-bearing). The Inspection Team were shown photographs demonstrating that this was repaired prior to leaving the field.

A small stretch (~1-2 meters in length) of sediment fence was observed partially buried within the reclaimed riparian area at AB-202 and was removed prior to the end of the inspection.

No additional corrective action is required.
