A Working Group is being established to develop new IAQM guidance for the assessment of dust (including PM) from mineral and secondary aggregate sites to accompany planning applications. The Group will be chaired by Claire Holman, and will have a maximum of ten members. If you are interested in joining please contact IAQM at firstname.lastname@example.org, giving a short biography highlighting your minerals experience. You will be expected to attend meetings, mainly held in Bristol, and to contribute to discussions and writing text. It is anticipated that the Working Group will have its first meeting early in the new year.
