How to Create or Renew an MSGP Notice of Intent (NOI) (RHODE ISLAND USE ONLY)

Overview: RIDEM’s Multi-Sector General Permit (MSGP) relies on the submission of an electronic document called a Notice of Intent (NOI) to gain coverage under its permit. A NOI for a general permit is notice to the NPDES permitting authority of the operator’s intent to be covered under the general permit. A NOI typically contains basic information about the site and the proposed discharge. By signing and submitting the NOI, the operator is certifying that the information submitted is true, accurate, and complete, that the operator meets the eligibility requirements, and that, when covered, the operator will comply with the permit conditions and effluent limitations. A fraudulent or erroneous NOI invalidates permit coverage. An incomplete NOI delays permit coverage until the NOI has been completed and the applicable review period has passed (i.e. 60 days for the RIDEM MSGP).
