200.01环境保护署(EPA)危险废物定义

1. a. EPA法规定义了两种类型的危险废物:特征废物和清单废物. A material is classified as a characteristic waste if: 1) it is a discarded solid, liquid or gaseous waste, 2)满足四种特征危险废物类别的一个或多个标准:可燃性, corrosive, reactive and toxic.

2. b. EPA listed wastes fall into three different categories: non-specific source (e.g., spent solvents) which are denoted as "F" - listed waste; specific source (e.g., spent metal plating bath) which are denoted as "K" - listed waste; and discarded chemical products which are given the prefixes "U" and "P". 美国环保署提供了大量被列为废弃化学产品的有害物质清单, specific and non-specific hazardous waste. “废弃”是指由于污染而不再需要的化学品, expiration, process change, spill, and so forth.
   
   Soil, concrete, 而其他被危险物质污染的材料也可视为危险废物. 处置受污染物质前，请与环境健康与安全部门联系咨询.

200.10 EPA Criteria for Defining Characteristic Hazardous Wastes

1. Ignitable Waste (EPA Waste Code - D001) -可燃废物符合下列一项或多项标准:
1. Liquids with a flash point less than 60 C (140 F);
2. Spontaneously combustible solids;
3. Ignitable compressed gases;
4. Oxidizers.
2. Corrosive Waste (EPA Waste Code - D002) —腐蚀性废物符合以下一项或多项标准:
   1. pH值小于等于2或大于等于12的水溶液.5; or
   2. A liquid that corrodes steel at a rate greater than 6.35 mm per year at 55 C.
3. Reactive Waste (EPA Waste Code - D003) - Reactive waste meets one or more of the following criteria:
   1. 通常不稳定的物质，在不爆炸的情况下会发生剧烈变化;
   2. 剧烈反应或与水形成潜在爆炸性混合物的物质;
   3. Materials that generate toxic fumes when mixed with water;
   4. 氰化物:含有能在pH值2到12之间释放有毒气体的物质的氰化物或硫化物.5; or
   5. Explosives
4. Toxicity Characteristic - A waste meets the characteristic of toxicity if: 1) it is a material listed in Table 1; or 2) a liquid (solution or mixture) waste possessing a Table 1 material at a concentration equal to or greater than that material's regulatory level; or 3) a solid waste, 经过EPA毒性特性浸出程序(TCLP), 所产生的渗滤液中，表1所列物质的浓度等于或超过该物质的规管限值. Refer to Table 1 below:

表1 -毒性特性污染物的最大浓度

注:上述化学品清单如有变更，EPA将不另行通知. 联系EHS以确保你有最新的信息.

200.20 EPA Listed Hazardous Wastes

1. Non-Specific Source Hazardous Waste ("F"-Listed Wastes) -非特定来源危险废物编号为一般废物流指定，如废溶剂和未使用的氯化苯氧农药.
   1. 脱脂作业产生的废溶剂(F001) -四氯乙烯, trichloroethylene, methylene chloride, 1,1,1-trichloroethane, carbon tetrachloride, and chlorinated fluorocarbons.
   2. Spent Halogenated Solvents (F002) - Tetrachloroethylene, methylene chloride, trichloroethylene, 1,1,1-trichloroethane, chlorobenzene, 1,1,2-trichloro-1,2,2-trifluoroethane, o-dichlorobenzene, trichlorofluoromethane, and 1,1,2-trichloroethane.
   3. Spent Non-Halogenated Solvents (F003) - Xylene, acetone, ethyl acetate, ethylbenzene, ethyl ether, methyl isobutyl ketone, n-butyl alcohol, cyclohexanone, and methanol.
   4. 废非卤代溶剂(F004)。甲酚和甲酚酸和硝基苯.
   5. Spent Non-Halogenated Solvents (F005) - Toluene, methyl ethyl ketone (MEK), carbon disulfide, isobutanol, pyridine, benzene, 2-ethoxyethanol, and 2-nitropropane.
   6. Discarded Unused Formulations Containing Tri-, 四氯化和五氯化苯酚及其衍生物(F027) -示例包括, tetra- and pentachlorophenols, 2,4,5-Trichlorophenoxy acetic acid (2,4,5-T), 2,4,5-Trichlorophenoxypropionic acid (2,4,5-TP or Silvex), and all salts, esters and amide derivatives. 还包括二苯并呋喃和二苯并二恶英或含有该物质的任何未使用的配方或材料. F027废物被认为是急性危险废物，受一(1)升的储存限制.
   
   注:以上列出的f种废物流定义只是大学产生者最常产生的废物流的一个例子. 有关其他f级废物流的更多信息，请联系EHS.
2. Specific Source Hazardous Wastes ("K" - Listed Wastes) -主要为工业废物流指定特定来源危险废物编号，很少给大学产生的废物流.

3. Discarded Chemical Products ("P" and "U" - Listed Wastes) -“P”或“U”所列废物是指废弃的商业化学产品, off-specification species, 这些化学产品的容器残留物和溢出残留物.
   1. Acute Hazardous Wastes ("P"-Listed Wastes): 被视为急性危险废物的化学品是那些以“P”开头的字母数字代码列出的化学品，并列入 APPENDIX A.
      1. Empty Containers -装有急性危险化学品的“空”容器在作为普通垃圾处理之前必须进行三次冲洗. 冲洗液必须合并，并作为危险废物提交处理.
      2. 有毒危险废物(“U”-列废物):这些材料被赋予“U”代码，并列入 APPENDIX B.
