Dust and Asbestos

Particulates including nuisance dust, breathable dust (PM10) and asbestos are monitored at the site boundary.  The monitoring locations under the permit are determined based on the prevailing wind and the location of sensitive properties. In response to community requests we have increased the number of dust monitoring points at the boundary of the site to provide measurement in all directions.  The interpretation of dust monitoring needs to take care to consider activities taking place off site for example agricultural activities such as ploughing and lime spreading.

Deposited dust
Dust is potentially generated at the site as a result of vehicle movements, wind blow and handling of dusty materials.  Measures are in place to suppress dust to prevent dust leaving the site. Deposited dust is often referred to as nuisance dust and is so called as it comprises large particles that are considered a nuisance where they settle for example on windows or paint surfaces.
















The exceedances in KCDD03 & KCDD04 can be attributed to activity not originating from the ENRMF site as the dominant wind direction during March was NNE (farmers’ fields are located to the East, South and South-West of the site). The KCDD04 exceedences in July, September and October are from bird faecal matter which was discovered on the deposited dust gauge and within the filter itself. The final exceedences of KCDD06 in December 2013 & February 2014 was due to high northerly winds blowing debris from open top vehicles running southerly adjacent into the monitoring point. A new monitoring point KCDD012 was installed on the boundary northerly adjacent to KCDD06 in March 2014. If future exceedences do occur in KCDD06 the data recorded from KCDD012 will determine if dust has escaped the site on its northern boundary.

Breathable dust (PM10)
Breathable dust is defined as small size particles of less than 10 micrometres in diameter. They are generated by similar mechanisms to deposited dust but the amount generated depends on the source material.  They are controlled by similar means.  They are important to monitor because they are inhalable and prolonged exposure to high levels can have health effects.
















The graph shows that all the results are very low at less than 9 micrograms/m3/day therefore well below the trigger level of 50micrograms/m3/day.

Asbestos is disposed of at the site.  Asbestos is only a risk if fibres become airborne hence the handling methods are designed to contain the asbestos.  All asbestos is received double wrapped and immediately covered on placement in the landfill.  As a precaution monitoring is undertaken at the site boundaries. Asbestos fibres can be present in the environment historically for example from vehicle brake linings.
















The graph shows that no asbestos fibres have been detected.
