This checklist was developed by the WCC Expert, Mr. Gilberto Marronato, and was applied in the pilot project on mercury management “Chloralkali Project – Uruguay” in April 2011. The project was financed by the Government of Norway and jointly implemented by the Government of Uruguay through Dirección Nacional de Medio Ambiente (National Environmental Directorate of Uruguay (DINAMA), the Word Chlorine Council through Clorosur, Efice S.A., and UNEP/DTIE Chemicals Branch. This checklist is still in DRAFT version and UNEP would welcome feedback on its suitability and applicability during further testing.
