Reclaiming the land
Over our 65-year history, TransCanada has successfully reclaimed hundreds of thousands of acres of land in arid grasslands, mountainous regions, sandy soils, muskeg, wetlands and rich crop lands. Even before construction begins, we collaborate with land owners and environmental experts to ensure that land’s agricultural capability and biological diversity is reclaimed to pre-construction conditions. We do this through by conserving top soil resources, replanting with native grass and plant species, restoring specific wildlife habitat and re-establishing stable historical drainage patterns. We also monitor environmental reclamation for years following construction.
Our reclamation procedures:
- Vegetation studies provide information on the vegetation communities crossed by the pipeline and provide the basis for preliminary seed mixes.
- Information about how the land is used is gathered, helping to determine the best construction and reclamation procedures.
- Soil surveys allow us to determine appropriate soil handling techniques to conserve the topsoil and prevent soil from mixing.
- Wildlife and fisheries surveys are used to identify areas where specific reclamation measures, such as specialized stream bank restoration measures (bio-engineering techniques) are required to re-establish fish and wildlife habitat.
Ongoing maintenance programs
We won’t disappear after PRGTP is built. You can expect ongoing maintenance activities including:
- Routine aerial surveillance of the pipeline.
- Annual testing of the cathodic protection systems.
- In-line inspections of the condition of the pipeline and investigative digs.
- Upgrades to the pipeline in areas adjacent to population.
- Repairs to water crossings and unstable slopes that the pipelines traverse.
- Mail educational material to residents along the pipeline right-of-way.
