Section 327IAC15-2-3. NPDES general permit applicability requirements

   (a) A general permit may regulate all designated categories of discharges for which a general permit exists except:

(1) as provided under section 6 or 9 of this rule or the applicable general permit; and

(2) discharges meeting the applicability requirements of a general permit that are already subject to individual NPDES permits prior to the effective date of a general permit.

  (b) Persons excluded from general permit regulation solely because they have an existing individual NPDES permit may request to be regulated under a general permit and may request that the individual NPDES permit be revoked or modified to remove the discharge from the existing permit. Upon revocation or expiration of the individual NPDES permit, the general permit shall apply to such discharges regulated under this article. This allowance to change from an individual NPDES permit to a general NPDES permit does not apply to municipal separate storm sewer system permittees who were issued an individual NPDES permit before January 1, 2000.

  (c) A person that holds an individual NPDES permit may have discharges regulated under an applicable general permit if such discharges are not addressed in the individual permit.
