Division BAT 27

United Kingdom

BAT is to monitor dust emissions from each animal house using one of the following techniques with at least the frequency given below.

A description of the techniques is given in Sections 4.9.1 and 4.9.2.
	Technique^f1	Frequency	Applicability
a	Calculation by measuring the dust concentration and the ventilation rate using EN standard methods or other methods (ISO, national or international) ensuring data of an equivalent scientific quality.	Once every year.	Only applicable to dust emissions from each animal house. Not applicable to plants with an air cleaning system installed. In this case, BAT 28 applies. Due to the cost of measurements, this technique may not be generally applicable.
b	Estimation by using emission factors.	Once every year.	Due to the cost of establishing emissions factors, this technique may not be generally applicable.

A description of the techniques is given in Sections 4.9.1 and 4.9.2.
