The UK participation in its preparation was entrusted by Technical Committee EH/2,Air quality, to Subcommittee EH/2/1, Stationary source emissions, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary.
