俄亥俄河谷水环境卫生委员会（ORSANCO）最近就水处理厂向俄亥俄河排放的市政和工业废水提出了一个问题。自1970年以来，污染控制标准1-70和2-70规定了委员会对市政和废水源废水处理的要求。然而，在审查中，这些规定的执行似乎并不统一，如果它们得到遵守的话。1981年，一项研究被授权研究这个问题。以1980年的美元计算，采用废物处理工艺的典型37毫升/天（10毫克/天）处理厂的最先进固体去除和处置的年总成本估计为108244美元（每3.7毫升/天[1毫克/天]29.65美元至434599美元（每3.7毫升/天[1毫克/天]119.07美元）。由于涉及大量资金，而且水质没有任何明显改善，因此认为要求水处理厂清除固体废物是不合适的。 已经提出了一项新的决议，旨在同时确保水质保护，并允许各州具有最大的灵活性，以建立一致性。如果该提案获得通过，委员会可以证明，控制措施应适当反映对环境效益和相关成本的平衡考虑。包括表格，数字。

A question was recently addressed by the Ohio River Valley Water Sanitation Commission (ORSANCO) regarding the municipal and industrial discharges to the Ohio River from water treatment plants. Since 1970, the commission's requirements for wastewater treatment from municipal and wastewater sources have been stipulated by Pollution Control Standard 1-70 and 2-70. However, on examination, enforcement of the regulations did not appear to be uniform, if they were followed at all. A study was authorized in 1981 to examine the problem. In 1980 dollars, total annual costs for state-of-the-art removal and disposal of solids were estimated for a typical 37-ML/d (10-mgd) treatment plant employing waste handling processes at $108,244 ($29.65 per 3.7 ML/d [1 mgd] to $434,599 ($119.07 per 3.7 ML/d [1 mgd]). Due to the significant sums of money involved and without any discernible improvements in water quality, the requirements for water treatment plants to remove waste solids were considered not to be appropriate. A new resolution, designed to simultaneously assure protection of water quality and allow maximum flexibility to the states, has been proposed to establish consistency. If this proposal is adopted, the commission can demonstrate that controls should properly reflect balanced considerations of environmental benefits and associated costs. Includes table, figures.
