现行地表水处理规则的变更可能会影响水务公司遵守新的消毒副产品规则。因此，reg neg委员会同意美国环保局将提出一项临时“强化”地表水处理规则，该规则将包括广泛的监管选项。将制定临时和最终规则，使其在要求系统遵守D-DBP规则的同时生效。强化地表水规则将监管隐孢子虫，修改避免过滤的标准，允许替代过滤技术，需要常规卫生调查，并可能增加处理要求。包括桌子。

Changes to the current Surface Water Treatment Rule will likely affect water utility compliance with the new Disinfection-Disinfection Byproducts Rule. As a result, the reg-neg committee agreed that the USEPA would propose an interim "enhanced" Surface Water Treatment Rule that would include a wide range of regulatory options. The interim and final rule would be developed so that it would be effective at the same time that systems would be required to comply with the D-DBP rule. The enhanced surface water rule would regulate cryptosporidium, modify criteria for avoiding filtration, allow alternative filtration technologies, require routine sanitary surveys, and may increase treatment requirements.
