由于不断增加和更严格的规定，1980年之前涂层或涂漆的大多数结构已被确定含有有害重金属。加利福尼亚州有毒有害物质项目包含在《加利福尼亚州环境卫生行政法规》第22篇第4部分中。根据标题22，涂料和油漆首先要进行测试，以确定其毒性。一旦被归类为有毒物质，移除过程中使用的移除材料和废磨料将再次进行测试，以确定这些材料是否需要作为危险废物处理。根据最近颁布的“土地禁令”规定，更严格的处置标准使最终处置成本增加了50%以上。 除了这一额外成本，加州只有一个有毒废物倾倒场，政治气候将不允许再获得许可。因此，不断增加的法规和垃圾场的缺乏给行业带来的负担决定了加快努力以成功应对降低危险废物处理和处置成本的新挑战的绝对必要性。本演示提供建议，以帮助业主、工程师、规范制定者、承包商和其他参与屏障保护的人员，通过油漆和涂料，使用替代的表面处理方法，以减少此类操作产生的危险废物数量，从而将处理和处置成本降至最低。

Because of ever-increasing and more stringent regulations, most structures coated or painted prior to 1980 have been determined to contain the objectionable heavy metals. The State of California program for toxic and hazardous materials is covered under the California Administrative Code of Environmental Health, Title 22, Division 4. Under Title 22, coatings and paints are first tested to determine their toxicity. Once classified as toxic, the removed material and spent abrasive used in the removal process is again tested to determine if the materials need to be treated as hazardous wastes. Under the recently enacted "Land Ban" regulations, the more stringent criteria for disposal has increased the cost for final disposal by more than 50%. In addition to this added cost, California only has one toxic waste dump, and the political climate will allow no more to be licensed. Accordingly, the burdens inflicted on industry by ever increasing regulations and lack of dumpsites dictate the absolute necessity to expedite efforts to successfully meet new challenges of reducing costs in handling and disposal of hazardous wastes. This presentation offers suggestions to assist owners, engineers, specifiers, contractors and others involved in barrier protection, via paints and coatings, in the use of alternate methods of surface preparation which are designed to reduce the quantities of hazardous wastes from such operations so as to minimize handling and disposal costs.
