Under Part I of the act an IPC system controls emissions to air, land or water for the most polluting industrial and similar processes. IPC is limited to prescribed processes (e.g. chemical, fuel and power, waste disposal, minerals etc.) by prior authorization. Authorization is based on the requirement for owners/controllers to prevent release of prescribed substances or, where this is not practicable, to reduce the release to a minimum. Any residual release must be rendered harmless. To achieve these aims, operators must use the best practicable means not entailing excessive cost (BATNEEC).
