How enforcement works in practice

Inspections are triggered by complaints, proactive monitoring, or observed incidents. Inspecting officers collect evidence, record the nature and source of the discharge, and may direct immediate actions such as stopping the discharge or containing contaminants. If the offence continues, the regulator can escalate to notices or prosecution based on the statutory framework. Time limits for filing appeals depend on the instrument issuing the enforcement action and are not specified on the cited pages; consult the relevant notice or consent for exact deadlines.
