The Comprehensive Environmental Response, Compensation, and Liability Act of 1980 required the federal government to establish criteria for setting priorities among releases of hazardous substances, pollutants, and contaminants. The U.S. Environmental Protection Agency responded by developing the Hazard Ranking System (HRS), which is a scoring system used to establish the National Priorities List (NPL). The Superfund Amendments and Reauthorization Act of 1986 required EPA to amend the HRS so it will more accurately assess relative risks and take into account certain specific elements of risk. On December 23, 1988, EPA published in the Federal Register the proposed rule to revise the HRS. EPA expects to issue the final rule in 1990 after reviewing public comments. This paper describes the proposed revisions and summarizes major technical findings that support the revisions. As a result of the HRS revisions, there may be some changes in the types of sites that score high enough to be placed on the NPL. A projection of those changes is discussed.
1980年的《综合环境反应、赔偿和责任法》要求联邦政府制定在有害物质、污染物和污染物排放之间确定优先顺序的标准。美国环境保护局对此做出回应，开发了危险等级系统（HRS），这是一种用于建立国家优先事项清单（NPL）的评分系统。1986年的《超级基金修正与再授权法》要求美国环境保护局修订HRS，以便更准确地评估相对风险并考虑某些特定的风险要素。1988年12月23日，美国环境保护局在《联邦公报》上公布了修订HRS的拟议规则。美国环境保护局预计在审查公众意见后于1990年发布最终规则。本文描述了拟议的修订内容，并总结了支持这些修订的主要技术发现。由于HRS的修订，得分足够高从而被列入NPL的场地类型可能会有一些变化。本文讨论了这些变化的预测情况。
