BAT/BATNEEC
"Best Available Techniques" (BAT) and "Best Available Techniques Not Entailing Excessive Costs" (BATNEEC) are based on commonly applied, judgement-based principles to assess whether risk controls/barriers are sufficient to manage an environmental impact. BATNEEC was introduced with the European 1984 Air Framework Directive and is only one example of commonly applied, criteria-based approaches to manage environmental risk towards acceptable levels. Principles are generally regulatory-based and include Best Available Control Technology (BACT), introduced by the US EPA, or Best Available Technology (BAT), introduced in Europe by OSPAR.
