This report contains the methodology and background information supporting the monthly air quality monitoring reports for High Speed Two (HS2). The monthly monitoring reports cover any complaints received, data recorded over the monitoring period, any periods which exceeded agreed trigger levels and the results of any investigations. Where HS2 works have been identified as the source, the reports include actions taken to resolve the issue and to prevent a recurrence. The HS2 monitoring includes PM10 and Nitrogen Dioxide.
HS2 Ltd and its contractors are required to undertake air quality and dust monitoring, and produce monthly reports, to comply with the Code of Construction Practice (CoCP). The reports are specific to each local authority area along the Phase One route.
The CoCP forms part of the Environmental Minimum Requirements (EMRs). The EMRs set out high-level environmental and sustainability commitments to be carried out during the planning and implementation of works along the Phase One route.
