3 GB Foreword This Standard has been drawn up to implement laws and regulations such as the Law of the People s Republic of China on the Prevention and Control of Environmental Pollution from Solid Waste and the Law of the People s Republic of China on the Prevention and Control of Radioactive Pollution, placing strict restrictions on imports of solid waste and controlling environmental pollution caused by smelt slag imported as raw material. This Standard sets out the environmental protection and control requirements for imported smelt slag. This Standard is one of a series of environmental protection control standards for imported solid waste. It applies to the management of importing relevant smelt slag listed in the Catalogue of Solid Waste Imported as Raw Materials. This Standard was first published in 1996 and revised for the first time in This is the second revision. Main amendments under this revision: -- Requirement added to include the dose rate value of external beam penetrating radiation of imported smelt slag; -- Requirement for the control of hazardous waste adjusted; -- Requirement for the control of general carried waste tightened up; -- Inspection and testing requirements amended. Environmental Protection Control Standard for Solid Waste Imported as Raw Materials - Smelt Slag GB will be repealed from the effective date of this Standard. The Soil Environmental Management Department and the Scientific Standards Department of the Ministry for Environmental Protection are responsible for the revision of this Standard. The main drafting body of this Standard is the Chinese Research Academy of Environmental Sciences. This Standard was ratified by the Ministry for Environmental Protection on (date) (month) 20 (year). The effective date of this Standard is (date) (month) 20 (year). The Ministry for Environmental Protection is responsible for the interpretation of this Standard. II

4 GB Environmental Protection Control Standard for Solid Waste Imported as Raw Materials Smelt Slag 1. Scope This Standard sets out the environmental protection and control requirements for imported smelt slag. This Standard applies to the management of importing the following smelt slag. Customs Commodity code Name of solid waste Granulated slag (including slag sand, and containing more than 25% manganese content) produced by smelting steel containing mainly manganese Oxide coating produced by rolling steel Steel and iron slag produced by smelting steel and iron with iron content greater than 80% 2. Normative reference documents This Standard cites provisions in the documents listed below. In the case of undated reference documents, the applicable version is the latest version in force. GB Standard for Identification of Hazardous Waste - Identification of Corrosivity GB GB GB GB GB Content SN/T 0570 Materials Standard for Identification of Hazardous Waste - Screening Test for Acute Toxicity Standard for Identification of Hazardous Waste - Identification of Extraction Toxicity Standard for Identification of Hazardous Waste - Identification of Flammability Standard for Identification of Hazardous Waste - Identification of Reactivity Standard for Identification of Hazardous Waste - Identification of Toxic Substance Standard Procedure for the Testing of Radioactive Pollution from Waste Imported as Raw SN/T Part 10 of the Standard Procedure for the Inspection and Quarantine of Waste Imported as Raw Materials: Smelt Slag The National Catalogue of Hazardous Waste (Order No 39 of the Ministry for Environmental Protection, National Development and Reform Commission and the Ministry of Public Security) 3. Terms and definitions The following terms and definitions apply to these standards. 3.1 Carried waste Other materials mixed with imported smelt slag in the manufacturing, collection, packaging and transportation processes (excluding packaging materials for imported smelt slag and other matters that need to be used in the course of transportation). 4. Control standard and requirements 4.1 Control of radioactive pollution from imported smelt slag shall comply with the following requirements: (a) smelt slag shall not contain any radioactive substance; (b) the dose rate of external beam penetrating radiation for imported smelt slag shall not exceed the normal natural radiation background value μgy/h at the port of entry; the level of α and β radioactive pollution on the surface of smelt slag: for any part of a surface of 300 cm 2, 1

5 GB the average maximum detected level of the α value shall not exceed 0.04 Bq/cm 2, while that of β shall not exceed 0.4 Bq/cm 2 ; (d) the radionuclide specific activity of smelt slag shall be lower than the limit values in Table 1. Table 1 Limit values of radionuclide specific activity Nuclide Specific activity(bq/g) 59 Ni 3x Ni 3x Mn Co Zn Fe Sr Cs / Cs U U Pu Am Eu Eu Nb 0.3 β-γ mixture of unknown components 0.3 α mixture of unknown components Smelt slag shall not contain any explosive munitions such as abandoned bombs or artillery shells. 4.3 Inclusion of the following carried waste is strictly restricted in smelt slag, and its overall weight shall not exceed 0.01 % of that of the imported smelt slag: (a) airtight containers; (b) waste listed in the National Catalogue of Hazardous Waste; (c) all other hazardous waste with one type or more of hazardous properties, such as corrosivity, toxicity, flammability and reactivity identified pursuant to Identification Standard GB GB Inclusion of carried waste other than materials listed above shall be restricted in imported smelt slag (including waste wood, waste paper, waste plastic, waste rubber, waste glass), and its overall weight shall not exceed 0.5% of that of the imported smelt slag. 2

6 5 Inspection and testing GB Inspection and testing pursuant to these standards shall be done through random sample testing, by opening and emptying crates, unpacking, unbaling and sorting imported waste loaded and transported in containers, and opening cabins for examination and post-unloading inspection of imported waste shipped in bulk. Where necessary, samples shall be sent to the laboratory for testing (including for radionuclide specific activity, hazardous properties, etc.). Results from a random sample testing shall apply to the entire consignment. 5.2 Inspection and testing pursuant to paragraph 4.1 of this Standard shall be done in accordance with Regulation SN/T Inspection and testing pursuant to 4.3c) of this Standard shall be done in accordance with the methods laid down in GB GB Inspection and testing pursuant to other requirements of this Standard shall be done in accordance with Regulation SN/T
