Title: Air dispersion climate from the Castle Cement works at Ribblesdale
Author: Environment Agency North West Region
Document Type: Monograph
Abstract:
This report studies the current situation and to assess the effect that various improvements put forward by Castle Cement will have on the ground level concentrations of key emitted pollutants. The emphasis of the study is on sulphur dioxide (S02) and particulates as these are the pollutants which are of greatest significance according to existing and proposed air quality criteria. Oxides of nitrogen (NOx) and odour have also been considered. S02 is emitted in significant amounts from each kiln stack; concentrations close to the new EPAQS standard (100ppb (270micronsg/m3) over 15 minutes) have been measured at ground level and short term concentrations above 50ppb (135micronsg/m3) have often coincided with the occurrence of odour. Particulates are emitted from both of the kiln stacks and also from cement mills within the Works; the EPAQS standard for particulates (50micronsg/m3 for rolling 24 hour average of PM10) has been exceeded in the vicinity of the site. The model used for most of the calculations is ADMS (Atmospheric Dispersion Modelling System).
