Timeline September 2021


We welcomed the report compiled by Defra’s Chief Scientific Adviser’s Office(External link) and have taken time to carefully consider the report and its recommendations.

Many of the report’s recommendations are consistent with measures we have required Walleys Quarry Ltd to implement, as set out in our Plan to reduce hydrogen sulphide emissions.

We have considered the report fully and our response to the recommendations can be found here.


A report by Defra’s Chief Scientific Adviser’s Office (CSAO) on Walleys Quarry Landfill odorous emissions has been published and can be found at: Science Search (defra.gov.uk)(External link)

We welcome the Report compiled by Defra’s CSAO. The good progress made on mitigating the concentration of hydrogen sulphide noted in the report has continued through 2022. The concentration of hydrogen sulphide in the gas management system has reduced further to around 1200ppm in Autumn 2022. All four monitoring facilities around the site have shown a monthly average concentration of hydrogen sulphide at or below the long-term health-based guidance value since May 2022. Many of the report’s recommendations are consistent with measures we have required Walleys Quarry to implement, as set out in our Plan to reduce hydrogen sulphide emissions. We will consider the report fully and if necessary review and revise the Plan in the future.
