House Bill No. 5525 establishes a rapid response program in Connecticut to manage and control aquatic invasive species, with a particular focus on hydrilla. The bill defines "rapid response" as a systematic effort to eradicate or control localized infestations and mandates the Connecticut Agricultural Experiment Station's Office of Aquatic Invasive Species (OAIS) to set criteria for newly discovered species eligible for rapid response. The Department of Energy and Environmental Protection (DEEP) is required to expedite permitting for these actions, and the OAIS is authorized to coordinate statewide efforts. Additionally, the bill modifies existing notification requirements for herbicide treatments, allowing for a single notice to waterfront property owners instead of two, and requires OAIS to assist in mapping invasive species populations and developing a state rapid response protocol.

House Amendment "A" further refines the bill by requiring OAIS to publish a list of qualifying species on its website and shifting the responsibility for developing the hydrilla rapid response protocol and statewide management plan solely to OAIS. The amendment allows OAIS to consult with other entities at its discretion and removes the requirement for DEEP to install hydrilla education signs and construct boat washing stations. The bill aims to streamline the permitting process for rapid response actions and alter notification procedures for herbicide treatments, ensuring efficient management of invasive species while addressing public health and environmental considerations. The provisions of the bill are set to take effect on October 1, 2026.
