b) Corrective action. If appropriate corrective action is not taken within a reasonable time, not to exceed 60 days unless the POTW or an affected industrial user demonstrates that a longer time period is reasonably necessary to undertake the appropriate corrective action, the Agency must either withdraw such discharge limits or require modifications in the revised discharge limits.

c) Public notice of withdrawal or modification.

Following such notice and withdrawal or modification, all industrial users to whom revised discharge limits had been applied must be subject to the modified discharge limits or the discharge limits prescribed in the applicable categorical pretreatment standards as appropriate and must achieve compliance with such limits within a reasonable time, not to exceed the period of time prescribed in the applicable categorical pretreatment standard.
