When pipelines are decommissioned, governments and environmental agencies typically require them to be permanently sealed. The reason for blocking them off is to prevent residual hazardous material, like gas, oil, or chemicals, from leaking into the environment and potentially harming local communities or leading to ecological contamination. Permanent sealing also avoids accidental reuse of the line and stops water from entering the pipe and possibly causing corrosion or flooding.
