Environment Agency Task Specific Analysis Air Quality Reports

In 2022 we conducted a short study using passive hydrogen sulphide (H2S) diffusion tube monitoring carried out in the vicinity of Walley’s Quarry Landfill Site in Silverdale between the 14 April 2022 and 14 July 2022.

The monitoring was carried out on behalf of the Environment Agency’s West Midlands team by TRL, with sample analysis provided by Gradko International Ltd. A copy of the report is below.

Diffusion Tube Report - 14 April 2022 - 14 July 2022

Interim Reports

We routinely produced Interim Reports which look at large sets of air quality data collected over six months or more, from the mobile monitoring facilities (MMFs). These reports are much more detailed than the Monthly Air Quality Reports. They identify the local sources of air pollutants and odour nuisances and quantifies the environmental impact of these pollutants on the surrounding area and the local community. So far we have produced the following Interim Reports:

Environment Agency – Study of Ambient Air Quality at Silverdale, Interim Report 1 – March to September 2021

Environment Agency - Study of Ambient Air Quality at Silverdale, Interim Report 2 - 4 March 21 to 31 May 2022

Environment Agency Task Specific Analysis Interim Air Quality Reports

We are also using the monitoring data to identify trends, correlate the data with weather patterns, look at the time and day of increases (and decreases), weather analysis and if certain activities on the site or in the local area, contribute to the issues. This is ongoing internal work and used to inform our regulatory activities. The report below provides a comparison between ambient air quality data at MMF9 Galingale View, Silverdale between the 6 March 2021 – 30 April 2021 and 6 March 2022 – 30 April 2022.

Environment Agency Air Quality Exceedance Reports

If the levels of hydrogen sulphide exceed the World Health Organisation’s (WHO) guideline level for health impacts (this is recorded over a 24hr average) we will inform all partners immediately and produce a report within 48hrs. Public Health England will be immediately informed so advice can be issued from our public health partners Staffordshire County Council. We call this an Exceedance Report. Exceedance Reports are published below.

Environment Agency Final Report

Once we complete a monitoring study we consider all the data that we have collected, finalise it and produce a comprehensive final report. As the current study has not concluded, there is no final report available for this study yet.

However we have two final reports from studies we undertook previously in 2017 and 2019. Please see below for more detail on this.

Previous Air Quality Monitoring (2017-19)

We have previously installed specialist air quality monitoring equipment in 2018 and 2019 to enable us to further understand the potential impact on air quality from Walleys Quarry landfill site. This equipment was installed on: 6 July 2017 - 14 February 2018 on the pumping station off Silverdale Road and 15 January 2019 - 25 June 2019 near the northern boundary of the site, on the grounds of Garner’s Garden Centre. Summaries of the previous air quality monitoring reports are available to view below.
