尽管乔治·布什总统的“湿地无净损失”政策基本上仍不明确，但监管机构和立法者正在加大保护湿地的力度。本文概述了这些努力。给出了一个定义，流程图显示了《清洁水法案》第404节的许可程序，并总结了保护湿地资源的联邦法律。在评估许可证申请时，已经制定了一个关于缓解措施的三步流程。《清洁水法》第404节中的否决权允许环境保护局否决可能损害市政供水、贝类养殖场和渔业区、野生动物或娱乐区的某些排放计划。对否决程序进行了详细描述。包括6个参考文献、表格、图表。

Despite the fact that President George Bush's policy of "no net loss of wetlands" remains largely undefined, regulators and legislators are making greater efforts to protect wetlands. This article offers an overview of those efforts. A definition is offered, a flow chart shows the generalized Clean Water Act section 404 permit process, and federal laws protecting wetlands resources are summarized. A three-step process regarding mitigation has been developed for use when evaluating permit applications. A veto allowance within the Clean Water Act section 404 allows the EPA to veto certain plans for discharges that might harm municipal water supplies, shellfish beds and fishery areas, wildlife, or recreational areas. The veto process is described in some detail. Includes 6 references, table, figure.
