自1989年以来，美国环境保护局采取了两项重要的规则制定举措，影响石棉水泥管的制造和使用。第一项是1989年颁布的一项法规，该法规禁止在一段时间内制造和销售大多数含石棉产品。这条规定对石棉水泥管有重大影响。第二项倡议是1991年初公布的一项法规，其中包括石棉的饮用水标准。根据法庭摘要中详述的理由，并在本文中总结，石棉水泥管生产商协会得出结论，EPA禁止石棉水泥管制造、进口、加工和商业分销的规则应被视为非法，并被搁置。

There have been two significant rulemaking initiatives by the U.S. EPA since 1989 affecting the manufacturing and use of asbestos cement pipe. The first was a regulation published in 1989 which prohibits the manufacture and distribution in commerce of most asbestos-containing products over a period of time. This rule has major impact on asbestos cement pipe. The second initiative was a regulation published in early 1991 which included drinking water standards for asbestos. Based on the reasons detailed in its court brief, and summarized in this paper, the Asbestos Cement Pipe Producers Association concluded that EPA's rule banning the manufacture, importation, processing, and distribution in commerce of asbestos cement pipe should be held unlawful and set aside.
