Simsbury 2025 MS4 Annual Report_Final.pdf

This is an annual MS4 stormwater compliance report prepared by the Town of Simsbury, Connecticut in accordance with its obligations under the CT DEEP General Permit for Discharge of Stormwater from Small Municipal Separate Storm Sewer Systems. The report documents the Town's stormwater management activities, compliance efforts, and regulatory progress for the fiscal year 2025. The document provides detailed information regarding the Town's municipal separate storm sewer system (MS4), including inventory of outfalls, mapping of the system, illicit discharge detection and elimination (IDDE) program activities, public education and outreach initiatives, pollution prevention and good housekeeping practices, and monitoring and reporting data. The report serves as the primary mechanism for demonstrating ongoing compliance with state permit requirements and documenting the Town's commitment to stormwater quality protection and management across its regulated service area.

This annual report fulfills the Town's mandatory reporting obligations to CT DEEP and establishes the baseline documentation that will inform the upcoming transition to the new MS4 General Permit. The report includes performance metrics, implementation schedules for ongoing compliance activities, and identification of any program modifications or enhancements undertaken during the reporting period. As the Town anticipates the issuance of a revised MS4 permit, this document provides essential historical context and current operational data that will be critical for the selected consultant to utilize when preparing the revised Stormwater Management Plan and updated IDDE program documentation referenced in the related RFP for MS4 stormwater compliance and industrial stormwater permit services.
