Minn. R. Part 7100.0240
In any case where, upon application of the responsible person or persons, the agency finds that by reason of exceptional circumstances the strict enforcement of any provision of parts 7100.0150 to 7100.0240 would cause undue hardship; that the use of cleaning or water conditioning agents containing phosphorus in excess of the permissible levels set forth herein is necessary for the public health, safety, or welfare; or that strict conformities with these limits would be unreasonable, impractical, or not feasible under the circumstances, the agency in its discretion may permit a variance therefrom upon such conditions as it may prescribe for prevention, control, or abatement of pollution in harmony with the general purpose of parts 7100.0150 to 7100.0240 and the intent of applicable state and national laws.
