Coordinated Stormwater Permitting
The Department of Environmental Management adopted the new Stormwater Design and Installation Standards Manual and filed new regulations that require the use of the new Manual for all OWR permitting programs. The revised manual became effective on January 1, 2011 and will be applied to permit applications received on or after that date.
All applicable development proposals must include a Stormwater Management Plan for review by the Department of Environmental Management.
APPLICATION GUIDANCE - In order to make it easier for applicants to address the requirements in the new Stormwater Design and Installation Standards Manual the Department of Environmental Management has developed a Stormwater Management Plan Guide which serves to outline key components that must be included in every Stormwater Management Plan submitted for review and approval. The Stormwater Management Plan Guide will help applicants understand how to prepare a Stormwater Management Plan that will satisfy any new requirements contained in the Stormwater Design and Installation Standards Manual as well as any existing regulatory requirements. The key components of a Storm Water Management Plan are provided below:
NEW APPLICATION CHECKLIST - Applicants must submit a completed application checklist with the program-specific application.
- Application Forms ( DEM Permitting Program Specific Application and a completed Stormwater Design and Installation Standards Manual Appendix A checklist).
- A Stormwater Site Planning, Analysis, and Design Report.
- A Construction Phase Erosion and Sediment Control Plan if the development project will disturb less than 1 acre of land, or a Storm Water Pollution Prevention Plan (SWPPP) if the development project will disturb greater than or equal to 1 acre of land.
- An Operation and Maintenance Plan which addresses operations and maintenance (O&M) of the proposed Best Management Practices (BMPs) after construction is completed and the site is in use. The Plan must address the stormwater management system and structural stormwater controls as well as pollution prevention and source controls.
The Fresh Water Wetlands (FWW), Water Quality Certification (WQC), Underground Injection Control (UIC), and the Rhode Island Pollutant Discharge Elimination System (RIPDES) Programs all require the use of the new RI Storm Water Manual. See below for a link to the appropriate application for each program. As of January 1, all applicants shall also submit a copy of the Appendix A checklist with the program application.
Municipal officials may also use this manual to support local storm water management programs by incorporating or referencing the manual into local ordinances. Please note that most municipalities and large operators of stormwater systems (e.g., Rhode Island Department of Transportation - RIDOT) are regulated under the Rhode Island Pollutant Discharge Elimination System (RIPDES) Municipal Separate Storm Sewer System (MS4) program and are required by their MS4 permits to have applicants who apply for local permits adhere to this manual. Because MS4 program requirements vary somewhat and are subject to change, users of the manual who are applying for local permits are encouraged to consult the RIPDES MS4 Program regulations and the local MS4 Operator ordinances or procedures, as part of developing a stormwater management plan for their project.
PRE-APPLICATION MEETINGS RECOMMENDED - OWR highly recommends that you arrange for a pre-application meeting to meet with the pertinent representatives from the OWR permitting programs during the planning and design phase of the project. To schedule a pre-application meeting with DEM, please contact Ron Gagnon, P.E. Chief of the Office of Customer and Technical Assistance at email@example.com or (401) 222-4700 ext.7500.
