Inter Pipeline officials said residents should avoid the trails near Saprae Creek east of the Airport.
Crews erected temporary fencing around the area in question, which will remain until further notice.
Corporate communications representative Steven Noble said on Aug. 29, the pipeline released some of its product.
“Inter Pipeline shut-down and isolated its Polaris and Corridor pipeline systems.”
He added the company’s safety response team mobilized to the area to conduct an investigation.
“Inter Pipeline’s top priority is the safety of the public, its workers, and protecting the environment. In addition to Inter Pipeline’s focus on containment and clean-up, environmental and wildlife monitoring has been established in the area.”
While nearby residents may notice an odour resulting from the incident, Inter said there is no risk to the public or waterways.
The pipeline transport company said heavy equipment will move to and from the trails, so recreation and off-highway vehicle users should avoid the area.
Inter said it will work with regulators and stakeholders and update the RMWB and surrounding communities on any further developments.
The head office for Inter Pipeline is in Calgary, Alta.
