NR 203.135(7)(a)(a) If the department proposes to modify a permit to authorize a substantial change to a nutrient management plan of a concentrated animal feeding operation (CAFO), the department is not required to provide notice of the substantial change under s. 283.39 (1) (a), Stats. The department shall provide a 14-day period, from the date on which notice is provided on the department’s Internet Web site in accordance with s. 283.39 (1) (d), Stats., for written comments on a proposed modification to authorize a substantial change to a nutrient management plan. A petition for an informational hearing on a proposed permit modification to authorize a substantial change to a nutrient management plan of a concentrated animal feeding operation shall be filed within 14 days of the date notice is provided under s. 283.39 (1) (d), Stats.
