How to Modify an Active MSGP Notice of Intent (Change 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.  An NOI contains basic information about the site and the proposed discharge. If any of the information on the NOI has changed during the permit cycle, a facility can modify the information by creating a change NOI. You should create a change NOI to update or correct information on your NOI, including:  Owner/operator address and contact information; Facility/site information; Changes in SIC code or industrial sector designation;  Changes to discharge information. 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.
