It is:
3. (1) Section 32 of the Act is amended by adding the following after subsection (3.1):
(3.2) If the Minister is of the opinion that a railway operation poses a significant threat to the safety of persons or property or to the environment, the Minister may, by notice sent to the person responsible for the railway operation, order the person to take the necessary corrective measures.
Why in that section do you mention the word “environment” and not in the previous one?
