Handbook for the 1979 Convention on Long Range Transboundary Air Pollution and Its Protocols
Format: PDF / Kindle (mobi) / ePub
The UNECE Convention on Long-range Transboundary Air Pollution, adopted in 1979, is one of the oldest multilateral international treaties on environmental protection, as well as being one of the most successful. This handbook reviews the background to, and objectives behind, the Convention, bringing together all the legal texts and ministerial statements made at the time of adoption of protocols, along with recent decisions of the Convention's Executive Body. It also contains current information on the structure of the Convention and the ratification status of its protocols.
Annex and the relevant decisions taken within the framework of the Inland Transport Committee of the Commission; and Introduce pollution control measures for major existing stationary sources, taking into (c) consideration the Technical Annex and the characteristics of the plant, its age and its rate of utilization and the need to avoid undue operational disruption. 3. The Parties shall, as a second step, commence negotiations, no later than six months after (a) the date of entry into force of

dedusting in fabric filters, which reduces the dust content to less than 20 mg/m3, shall be considered as BAT. When BAT is used also for minimizing fbgitive emissions, the specific dust emission (including fugitive emission directly related to the process) will not exceed the range of 0.1 to 0.35 kg/Mg steel. There are many examples of clean gas dust content below 10 mg/m3 when fabric filters are used. The specific dust emission in such cases is normally below 0.1 kgMg. 32. For the melting of
ventilation; process exhausts; products, particularly hydrogen; and waste water. With regard to emissions into air, Hg diffusely emitted from the cells to the cell room are particularly relevant. Preventive measures and control are of great importance and should be prioritized according to the relative importance of each source at a particular installation. In any case specific control measures are required when mercury is recovered from sludges resulting fiom the process. 62. The following
emitted mass flow of particulates is above 10 kglh. If emissions are monitored, the concentrations of air pollutants in gas-carrying ducts have to be measured in a representative fashion. If particulate matter is monitored discontinuously, the concentrations should be measured at regular intervals, taking at least three independent readings per check. Sampling and analysis of all pollutants as well as reference measurement methods to calibrate automated measurement systems shall be carried out
