Getting started. If you need to submit an NOI, you would need to submit an NOI at least 15 days prior to a
discharge (allow some time do develop the NOI online and mail a signed copy to DHEC). Some operators will be
covered by this permit without the need to submit an NOI (i.e., those operators that don't expect to exceed
threshold for a given use pattern). A link to the NOI form can be found at our web site noted below.
