Best available technology (or just BAT) is a term applied with regulations on limiting pollutant discharges with regard to the abatement strategy. Similar terms are best available techniques, best practicable means or best practicable environmental option. The term constitutes a moving target on practices, since developing societal values and advancing techniques may change what is currently regarded as "reasonably achievable", "best practicable" and "best available".

A literal understanding will connect it with a "spare no expense" doctrine which prescribes the acquisition of the best state of the art technology available, without regard for traditional cost-benefit analysis.[citation needed] In practical use, the cost aspect is also taken into account.[1]

"But no person shall be subject to the foregoing penalties for any act done in the exercise of any right to which he is by law entitled, if he prove to the satisfaction of the court, before whom he is tried, that he has used the best practicable means, within a reasonable cost, to render harmless the liquid or solid matter so permitted to flow or to be put into waters."

Best practicable means was used for the first time in UK national primary legislation in section 5 of the Salmon Fishery Act 1861[2] and another early use was found in the Alkali Act Amendment Act 1874,[3] but before that appeared in the Leeds Act of 1848.

The BAT concept was first time used in the 1992 OSPAR Convention for the protection of the marine environment of the North-East Atlantic for all types of industrial installations.

Some doctrine deem it already acquired the status of customary law.

In the United States, BAT or similar terminology is used in the Clean Air Act and Clean Water Act.

European Union directives

Best available techniques not entailing excessive costs (BATNEEC), sometimes referred to as best available technology, was introduced in 1984 with Directive 84/360/EEC and applied to air pollution emissions from large industrial installations.[4]

In 1996, Directive 84/360/EEC was superseded by the Integrated pollution prevention and control directive (IPPC), 96/61/EC, which applied the framework concept of Best Available Techniques (BAT) to the integrated control of pollution to the three media air, water and soil. The concept is also part of the directive's recast in 2008 (2008/1/EC) and its successor directive, the Industrial Emissions Directive 2010/75/EU published in 2010.

According to article 15(2) of the Industrial Emissions Directive, emission limit values and the equivalent parameters and technical measures in permits shall be based on the best available techniques, without prescribing the use of any technique or specific technology.[5]

The directive includes a definition of best available techniques in article 3(10):

"best available techniques" means the most effective and advanced stage in the development of activities and their methods of operation which indicates the practical suitability of particular techniques for providing the basis for emission limit values and other permit conditions designed to prevent and, where that is not practicable, to reduce emissions and the impact on the environment as a whole:

- "techniques" includes both the technology used and the way in which the installation is designed, built, maintained, operated and decommissioned;
- "available" means those developed on a scale which allows implementation in the relevant industrial sector, under economically and technically viable conditions, taking into consideration the costs and advantages, whether or not the techniques are used or produced inside the Member State in question, as long as they are reasonably accessible to the operator;
- "best" means most effective in achieving a high general level of protection of the environment as a whole.

BAT for a given industrial sector are described in BAT reference documents (BREFs) as defined in article 3(11) of the Industrial Emissions Directive. BREFs are the result of an exchange of information between European Union Member States, the industries concerned, non-governmental organisations promoting environmental protection and the European Commission pursuant to article 13 of the directive. This exchange of information is often called the Sevilla process because it is steered by the Institute for Prospective Technological Studies of the European Commissions' Joint Research Centre, which is based in Seville. The process is described in detail in Commission Implementing Decision 2012/119/EU.[6] The most important chapter of the BREFs, the BAT conclusions, are published as implementing decisions of the European Commission in the Official Journal of the European Union. According to article 14(3) of the Industrial Emissions Directive, the BAT conclusions shall be the reference for setting permit conditions of large industrial installations.

United States environmental law

The Clean Air Act requires that certain facilities employ Best Available Control Technology to control emissions.

...an emission limitation based on the maximum degree of reduction of each pollutant subject to regulation under this Act emitted from or which results from any major emitting facility, which the permitting authority, on a case-by-case basis, taking into account energy, environmental, and economic impacts and other costs, determines is achievable for such facility through application of production processes and available methods, systems, and techniques, including fuel cleaning, clean fuels, or treatment or innovative fuel combustion techniques for control of each such pollutant.[7]

The Clean Water Act (CWA) requires issuance of national industrial wastewater discharge regulations (called "effluent guidelines"), which are based on BAT and several related standards.

...effluent limitations for categories and classes of point sources,... which (i) shall require application of the best available technology economically achievable for such category or class, which will result in reasonable further progress toward the national goal of eliminating the discharge of all pollutants.[8] ...Factors relating to the assessment of best available technology shall take into account the age of equipment and facilities involved, the process employed, the engineering aspects of the application of various types of control techniques, process changes, the cost of achieving such effluent reduction, non-water quality environmental impact (including energy requirements), and such other factors as the Administrator deems appropriate.[9]

A related CWA provision for cooling water intake structures requires standards based on "best technology available."

...the location, design, construction, and capacity of cooling water intake structures reflect the best technology available for minimizing adverse environmental impact.[10]

International conventions

The concept of BAT is also used in a number of international conventions such as the Minamata Convention on Mercury, the Stockholm Convention on Persistent Organic Pollutants, or the OSPAR Convention for the protection of the marine environment of the North-East Atlantic.
