Bill > H0579

This bill establishes a permitting process for applying alum, a chemical compound containing aluminum used to bind phosphorus and reduce harmful cyanobacteria blooms in Vermont waters, to prevent negative impacts on aquatic life and water quality. It requires anyone wishing to discharge alum into state waters to first obtain a permit from the Secretary of Natural Resources, with applications limited to the municipalities where the affected waterbody is located. Before issuing a permit, the Secretary must adopt rules by December 1, 2026, that outline specific criteria, including demonstrating direct harm from blooms, exploring alternative solutions, informing the public, reducing external phosphorus sources, meeting water quality standards for aluminum, monitoring aquatic life and water quality both before and after treatment, and covering all associated costs. The bill also clarifies that no alum permits can be issued until these rulemaking requirements are met.
