This Standard is proposed by the Pollution Control Department of the State Environmental Protection Administration. This Standard is under the control of the Science and Technology Standard Department of the State Environmental Protection Administration. This Standard is drafted by the State Environmental Monitoring General Station and China University of Science and Technology. This Standard is initially issued for this time and implemented as of Mar.01, 2000. The State Environmental Protection Administration is responsible for the interpretation of this Standard. w w w . b z f x w . c o m 1 National Standard for Environmental Protection GWKB 21999 Pollution Control Standard for Hazardous Wastes Incineration 1. Scope This Standard specified the site selection principle for hazardous wastes incineration facilities, basic technical specifications for incineration, the maximum allowable effluent limits for incineration exhaust pollutants, the disposal rules for incineration residues and corresponding environmental monitoring from the need of environmental pollution control during the treatment of hazardous wastes incineration. This Standard is applicable to the design, environmental impact evaluation and acceptance of hazardous wastes incineration facilities except those for explosive and radioactive wastes, as well as the pollution control during operation. 2.
