Minn. R. Part 7049.0370
A POTW receiving wastes from an industrial user to which a categorical pretreatment standard applies may, at its discretion and subject to the conditions of this part, grant removal credits to reflect removal by the POTW plant of pollutants specified in the categorical pretreatment standard. The POTW authority may grant a removal credit equal to or, at its discretion, less than its consistent removal rate. Upon being granted a removal credit, each affected industrial user shall calculate its revised discharge limits according to part 7049.0390. Removal credits may only be given for indicator or surrogate pollutants regulated in a categorical pretreatment standard if the categorical pretreatment standard so specifies.
