NR 210.12NR 210.12 Blending.

NR 210.12(1)(1) Findings. When issuing a permit, the department may, following review of the permit application and other information provided by the permittee, find that all the following conditions are met:

NR 210.12(1)(a)(a) Excessive flow received at a sewage treatment facility will cause severe property damage if blending is not approved, including damage to the sewage treatment facility which will cause the facility or portions thereof to become inoperable;

NR 210.12(1)(b)(b) The permittee demonstrates, as required by this section, that there are no feasible alternatives to blending such as the use of auxiliary treatment facilities, retention of untreated sewage, or the provision of other treatment and operational alternatives, and;

NR 210.12(1)(c)(c) The permittee is required to notify the department of each blending occurrence as provided in sub. (6).

NR 210.12(2)(2) Blending approvals. Blending is prohibited, but may be approved by the department and included as a specific condition in a permit. Blending may only be approved and included as a condition in a permit when all the following conditions are met:

NR 210.12 NoteNote: The department may initiate enforcement action under s. 283.89, Stats., for any blending not specifically included as a condition in a permit.

NR 210.12(2)(a)(a) The department determines that blending may be necessary during wet weather and other high flow conditions to avoid severe property damage to the sewage treatment facility. Severe property damage occurs when the facility becomes inoperable due to loss of treatment efficiency from washout of biological media.
