Calderdale Council monitors air quality in the Borough. This is in line with its responsibilities under the local air quality management legislation and guidance. This monitoring, has been done for more than ten years. This is in addition to the investigation of complaints about air pollution from factories, or in Smoke Control Areas.
The Environment Act 1995 specifies eight pollutants all councils must consider as part of a national Air Quality Strategy. These include nitrogen dioxide, fine particles (PM10) and others.
Currently, Council monitoring concentrates on traffic-related nitrogen dioxide. This has been identified as exceeding the air quality objectives in seven areas. These areas have been designated as Air Quality Management Areas (AQMAs). Particulate matter is also being monitored in connection with road traffic emissions and public health.
Most of the Council's nitrogen dioxide monitoring is carried out using diffusion tubes. There are also three automatic monitoring sites in the Borough at Salterhebble, Sowerby Bridge and Hebden Bridge.
In 2015 the Council installed particulate monitors at its automatic monitoring stations. The results will be presented in future air quality reports.
