UK Best Available Techniques Conclusions guidance under the Industrial Emissions Directive
UK Best Available Techniques Conclusions
This guidance provides information on how we interpret and apply the Best Available Techniques (BAT) Conclusions under the Industrial Emissions Directive (IED).
It supports you as the operator by explaining how we consider the BAT Conclusions during permit applications and permit reviews. This guidance is commonly referred to as ‘Cross Cutting Guidance’.
What you will find in the guidance
Understanding BAT and the regulatory framework
Explains the role of the Industrial Emissions Directive (IED), BAT Conclusions (BATc), and how they are used to set permit conditions and drive permit reviews.
Permit reviews and implementation
Covers BAT review requirements, review timescales, determining the main activity at an installation, and managing operational changes that may affect permit requirements.
Applying BAT in permitting
Provides guidance on interpreting BAT techniques, narrative BAT conclusions, environmental objectives and permit conditions.
Emissions limits and environmental performance
Explains BAT-Associated Emission Limits (BAT-AEL), BAT-Associated Emission Performance Limits (BAT-AEPL), emission limit values (ELVs), averaging periods, applicability statements and exemptions.
Monitoring and compliance
Covers monitoring requirements, confidence intervals, low-level monitoring, and assessing compliance with BAT-related permit conditions.
Water emissions
Provides guidance on direct and indirect discharges to water and groundwater protection.
Derogations from the BAT AEL Range
Explains how the IED allows derogations from BAT-AELs where compliance costs are disproportionate to environmental benefits.
Site management and environmental protection
Covers baseline reports, environmental management systems (EMS), and measures to protect soil, groundwater and the wider environment.
Future developments and emerging techniques
Explains how emerging technologies may be considered and the circumstances in which temporary derogations may be granted to trial innovative techniques.
