Permittees seeking reissuance of their NPDES permit under Section 502.101(d) must apply for reissuance of the permit, using proper forms, at least 180 days before the permit expires. The Agency will notify those persons of the need for renewal at least 60 days before the date on which the renewal application must be submitted; however, failure to do so does not excuse noncompliance with this Chapter.
