BAT conclusions on waste water and waste gas from chemicals sector published

The BAT conclusions constitute a statement of Best Available Techniques on end-of-pipe waste water treatment, control of particulate matter emissions and whole effluent assessments.

08 August 2016

Tougher standards will be imposed on European chemical installations subject to the Industrial Emissions Directive following the publication of Best Available Techniques (BAT) conclusions for common waste water and waste gas treatment/management systems in the chemical sector. 

The BAT conclusions are relevant to:

  • environmental management systems
  • waste water management, collection and treatment
  • waste gas management and collection
  • diffuse emissions of Volatile Organic Compounds to air
  • odour emissions
  • noise emissions. 
  • There are Associated Emission Levels (AELs) for emissions to water of total organic carbon/chemical oxygen demand, total suspended solids, total (inorganic) nitrogen, total phosphorous, absorbable organically bound halogens, chromium, copper, nickel and zinc. 

Most AELs for emissions to air have been moved to a separate BREF on waste gas in the chemical industry. 

In the UK, the relevant environmental regulator (the Environment Agency in England, NRW in Wales, SEPA in Scotland and NIEA in Northern Ireland) will enforce these standards through the environmental permitting regime. Our environmental law specialists assist operators throughout the UK with all aspects of the permitting regime including applications, variations, appeals, regulatory engagement and enforcement action. 

The future status and application of BREF notes and technical guidance after Brexit will require careful attention.
