Amendment to the Environmental Permitting (England and Wales) Regulations 2017

This amendment to the Environmental Permitting Regulations will introduce new controls for electricity generators which which emit high levels of NOx relative to other generators. The plants will be permitted and subject to controls depending upon the age of the plant, emission levels, hours of operation and impact on local air quality. The purpose of the controls is to deter a further increase in the use of high NOx emitting generators, and to reduce emissions and concentrations of key pollutants, to aid compliance with international air quality guidelines, national emission ceilings and the Ambient Air Quality Directive.
