1992年至1993年，美国环境保护局（USEPA）根据《联邦咨询委员会法案》（FACA）召开了一次协商规则制定过程，以制定一种共识方法，同时解决消毒副产品（DBPs）和水传播病原体造成的潜在健康风险。在DBP防护和微生物病原体防护之间可能会进行无意风险权衡，这一事实使过程复杂化。由于影响这两种风险评估的不确定性，情况变得更加复杂。监管谈判委员会设计了一种分阶段的监管方法，第二个FACA委员会于1996-97年最终确定了该方法。本文总结了效益成本分析中的DBPs部分，该部分是在这些过程中开发的，后来由美国环保局进行了改进，以更全面地解决与该规则的效益有关的不确定性。 包括17个参考文献、表格、图表。

In 1992-93, the US Environmental Protection Agency (USEPA) convened a negotiated rulemaking process under the Federal Advisory Committee Act (FACA) to develop a consensus approach to simultaneously addressing potential health risks posed by disinfection byproducts (DBPs) and waterborne pathogens. The fact that inadvertent risk-risk tradeoffs might be made between protection from DBPs and protection from microbial pathogens complicates the process. It is further complicated by uncertainties that affect the assessment of both risks. The regulatory-negotiations committee devised a staged approach to regulation that a second FACA committee finalized in 1996-97. This article summarizes the DBPs side of the benefit-cost analysis that was developed during these processes and later refined by USEPA to more fully address uncertainties regarding the rule's benefits. Includes 17 references, tables, figures.
