§ 15.12.405. Extent of mandatory reductions.

Whenever the city council or city manager has made a determination pursuant to Section 15.12.404, the city engineer or other authorized employee or agent of the city shall order regulated industrial users to reduce their present volume of flow, concentration of BOD or suspended solids, or any combination thereof to or below the maximum allowable regulated flow (MARF). MARF shall be either:

1.

Their present volume of flow, concentration of BOD, or suspended solids, or any combination thereof, minus the level of reduction, as hereinafter provided, plus the amount of any voluntary reduction accomplished pursuant to Section 15.12.402 which amount shall be determined by the city engineer to his satisfaction on the basis of date submitted by the user; or

2.

Their base average discharge minus the level of reduction as hereinafter provided; whichever is highest.

The city engineer shall determine the level of reduction which shall be a percentage of the users' base average discharge up to a maximum of ten percent of the base average discharge based upon a reasonable estimate of the reduction necessary to alleviate the threat of interference. The city engineer shall order such reduction by written notice to regulated industrial users who shall make such reduction effective within eight hours after notice. He may increase or decrease the percentage or reduction within the maximum ten percent range by further written notice to each regulated industrial user. Mandatory reductions shall cease upon a determination of the city manager or city council that the occasion for the reduction has ceased.
