This standard is formulated for the purpose of implementing Environmental Protection Law of the People’s Republic of China and Cleaner Production Law of the People’s Republic of China, protecting the environment, and providing technical supports and guidelines on cleaner production for lead smelting industrial enterprises. This standard provides the general requirements for the lead smelting enterprises to conduct cleaner production on the basis of meeting national and local emission standards and in line with the existing industrial, equipment and managerial levels of this industry. This standard includes three levels, the first level represents the international advanced level of cleaner production, the second represents domestic advanced level of cleaner production, and the third represents domestic basic level of cleaner production. This standard shall be amended at a proper timing with the technological development. This standard provides the general requirements for cleaner production of the lead smelting industry. This standard classifies the indicators for cleaner production into six kinds, that is, requirements for production techniques and equipment, indicator for the use of resources and energy, product indicator, pollutant indicator (prior to the end-of-pipe treatment), indicator for waste recycling, and environmental management requirements. This standard is applicable to the assessment of cleaner production of lead smelting enterprises, the estimation of the potential and chance of cleaner production, the performance assessment of cleaner production and the performance disclosure system for cleaner production, as well as environmental management systems like environmental impact assessment and pollutant discharge permit. This standard is the first version.
