Classification or Categorization System
Define key terms: ICPE and operator, activity and facility

The classification regime is the determining factor for the effective application of the law, as it establishes the legal, technical, and financial framework within which the facility may be established or continue to operate.

The classification regime is defined based on a quantitative threshold specified for the facility (or ICPE category) in question in the nomenclature of classified facilities.

Under the law governing classified facilities, there are three classification regimes corresponding to four increasing levels of applicable regulatory constraints.
