Rule 5 & Information

Rule 5

Rule 5 (327 IAC 15-5 (PDF)) is a general permit, and as such it is not "issued" in the same manner as an individual NPDES permit would be issued. To obtain an individual permit the applicant submits an application form, IDEM drafts site specific permit conditions and a public comment period is held to solicit proposed modifications to that draft, after which IDEM may revise its draft before issuing a finalized permit.

Rather, Rule 5 was "conditionally issued" to all future "project site owners" at the time that the rule was adopted by the Indiana Water Pollution Control Board. The permit conditions within Rule 5 apply universally to all "project site owners" who are eligible to operate under the rule, and opt to do so.

Notice of Intent

As with any general NPDES permit, there is no 30-day public comment period because the public already had the opportunity to comment on the permit conditions in the Rule during the rule-making process that lead up to the adoption of Rule 5. Hence, the "application" for a Rule 5 permit is called a Notice of Intent (NOI) because the "applicant" or "project site owner" is essentially submitting a NOI letter notifying IDEM of his or her intent to operate their proposed construction project in a manner consistent with the "permit conditions" established by Rule 5. The "project site owner" also notifies the public - in a newspaper - of his or her intent to operate under Rule 5.
