美国环境保护局（USEPA）于1991年6月7日颁布了铅和铜法规。1996年4月12日，该机构提议对这些法规进行轻微修订，以简化实施并减轻报告负担。拟议的变更不会影响基本的监管要求，但旨在使实施更容易，并降低成本。通知还要求对该机构正在考虑的几项措施发表意见，以进一步减轻执行负担。 本文对建议的修订进行了评述。

Regulations for lead and copper were promulgated by the US Environmental Protection Agency (USEPA) June 7, 1991. On April 12, 1996, the agency proposed minor revisions to these regulations in order to streamline implementation and reduce reporting burdens. The proposed changes do not affect basic regulatory requirements but are intended to make implementation easier and to reduce costs. The notice also requested comment on several measures that the agency is considering to further ease the implementation burden. The proposed revisions are reviewed in this paper.
