1989年，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。首次提出的饮用水中石棉的最大污染物水平目标（MCLGs）；第二项是一项法规，禁止制造和销售大多数含石棉产品，包括管道。本文概述了这些法规，强调了后者，并给出了石棉水泥管生产商协会反对这些法规的理由。

During 1989, the US Environmental Protection Agency took two significant rulemaking initiatives affecting asbestos cement pipe. The first proposed maximum contaminant level goals (MCLGs) for asbestos in drinking water; the second was a regulation banning the manufacture and distribution of most asbestos-containing products, including pipe. This paper provides an overview of the regulations, emphasizing the latter, and gives the Asbestos Cement Pipe Producers Association arguments against them.
