35 Ill. Adm. Code 502.204
Renewal
Section 502
Section 502.204Â Renewal
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.
