Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, which incinerator operators hold (a) permits and (b) revised permits that require them to monitor emissions of (a) PM10, (b) PM2.5, (c) PM1 and (d) PM0.1 and if he will publish the results of that monitoring.

No incinerators are required to monitor these emissions. As per the answer of 19 April 2018 to Question 135379, all new waste incinerators are required to carry out a one-off monitoring exercise after the plant is commissioned to determine the size distribution of particulates in the exhaust gases (currently only for PM10 and PM2.5). The results of this monitoring are published on the public register which is available online at:
