Section 880-RICR-00-00-4.17 - Stormwater Management4.17.1PurposeA. The purpose of these regulations is to provide for effective management of the stormwater system within the Park. These regulations provide a mechanism for mitigating the damaging effects of uncontrolled and unplanned stormwater runoff. They improve the public health, safety and welfare by establishing methods for controlling the introduction of pollutants into the ground and surface waters under and adjacent to the Park. These regulations establish the guidelines for managing the stormwater system including design, regulatory coordination, construction, operation, maintenance, inspection and enforcement. These regulations identify the concept of implementing stormwater drainage service charges based on each property's contribution of stormwater runoff to the system.4.17.2Stormwater RegulationA. There are six regulations that affect stormwater management ranging from QDC's enabling legislation to state and federal mandated programs. Under these programs, stormwater runoff from streets, parking lots, construction sites, industrial facilities and/or other impervious surfaces are regulated. These regulations include: 1. R.I. Gen. Laws § 42-64.10-6 entitled "Quonset Development Corporation" establishes a stormwater management and conveyance system and regulates connections, user fees, charges and assessments.2. Under 250-RICR- 150-10-1.32, Quonset Business Park is a designated A Municipal Separate Storm Sewer System (MS4) and QDC has prepared a stormwater management program that identifies measures to reduce the discharge of pollutants into stormwater system that drains into surface water bodies.3. A Rhode Island Pollutant Discharge Elimination System (RIPDES) Construction General Permit shall be obtained in accordance with 250-RICR- 150-10-1. All stormwater discharges associated with construction including clearing, grading, excavation, and filling of one acre of more require a permit. The permit requires the development of a Stormwater Management Plan consistent with 250-RICR- 150-10-7. In addition, a Soil Erosion and Sediment Control Plan (SESCP) must be prepared.4. Discharges of stormwater associated with specific categories of industrial facilities also are required to obtain a RIPDES General Permit for Storm Water Discharge Associated with Industrial Activity in accordance with 250-RICR- 150-10-1 for material handling and storage, equipment maintenance and cleaning, scrapyards, landfills, shipyards and other types of activities.5. Stormwater runoff discharging toward a wetland or a conveyance system that discharges into a wetland requires a wetland permit in accordance with 250-RICR- 150-15-1.6. Stormwater Discharge into the Coastal Zones: The Coastal Resources Management Council (CRMC) regulates discharges into the Coastal Zone including freshwater wetlands in the vicinity of the coast. The areas of RIDEM and CRMC jurisdictional boundaries within the Park are shown on the RIDEM online GIS map: http://ridemgis.maps.arcgis.com/apps/webappviewer/index.html? id=87e104c8adb449eb9f905e5f18020de5. Any proposed discharge, construction, or maintenance activity into or within this boundary requires a CRMC Assent.
B. Storm Sewers and Connections 1. No persons shall uncover, make any connections with or opening into, use, alter, or disturb any QDC stormwater system or appurtenances without submitting the appropriate information consistent with §§ 4.8.5 and 4.17 of this Part and obtaining prior approval.2. All costs and expenses incidental to the installation and connection of the stormwater and storm infrastructure shall be borne by the user who shall indemnify the QDC from any loss or damage that may indirectly be occasioned by the installation of the storm sewer.3. No persons shall make connection of sanitary sewer lines or illicit discharges to a storm drain that in turn is connected directly or indirectly to a QDC stormwater system.4. The user of the stormwater system shall notify QDC when the storm drain is ready for inspection and connection to the QDC storm drain. The connection shall be made under the supervision of the QDC.5. All excavations for storm drain installation shall be adequately guarded with barricades and lights so as to protect the public from hazard. Streets, sidewalks, pavements and other QDC property disturbed in the course of the work shall be restored by the owner in a manner satisfactory to the QDC.C. Stormwater Review Procedure 1. For connections or alterations to QDC's stormwater, the applicant shall submit the drainage design and requirements identified in §4.17.2(D) of this Part, "Project Drainage Report" for QDC Technical Review Committee (TRC) approval. The TRC will review and provide comments to the applicant if necessary. Upon approval, the TRC will provide the applicant with an approval letter to accompany the RIDEM RIPDES permit and RIDEM Water Quality Certification applications. RIDEM will issue the final permit and a copy of this permit is to be filed with QDC. QDC manages this permit program which enables a more streamlined review by RIDEM.2. For Stormwater Discharge into Freshwater Wetland Areas and Stormwater Discharge into Coastal Zone, the applicant shall submit the drainage design as detailed in §4.17.2(D) of this Part, to the TRC. TRC will review and approve the drainage design and give the applicant an approval letter to accompany the Freshwater Wetlands and Coastal application.D. Project Drainage Report 1. The purpose of the Project Drainage Report is to identify and propose specific solutions to stormwater runoff and water quality impacts resulting from proposed development within the Park. The report must comply with 250-RICR- 150-10-7, Appendix K: Hydrologic & Hydraulic Modeling Guidance.
