Mr. Jack Nolan:

On the issue of covering tanks, it has been proposed as part of the Ag Climatise strategy for greenhouse gases and agriculture, and the ammonia handbook of good practice. Covering external stores is a measure to reduce ammonia losses. Agriculture is responsible for more than 99.5% of ammonia emissions. Wind travelling over slurry strips it of ammonia, from which the idea of the covers stemmed. We are in discussions with the EPA. In countries like Denmark, a crust or floating beads are considered to be a cover. No decision has been made that every farmer will have to put a tent or a floating cover on an open store. It is likely in the future that some type of cover will be required to prevent ammonia losses from slurry storage.
