The bill H.152 proposes to allow the Secretary of Natural Resources in Vermont to authorize pilot or demonstration projects aimed at treating or destroying emerging contaminants without the need for a standard permit. These projects are defined as temporary uses of prototype equipment or processes to collect data for full-scale treatment systems and assess their feasibility while minimizing environmental impacts. The authorization for such projects is limited to a maximum duration of one year and is subject to specific conditions to ensure the protection of human health and the environment.

Key provisions of the bill include the establishment of definitions for "emerging contaminants" and "pilot or demonstration projects," as well as the requirements for application submissions, which must detail the proposed treatment systems, anticipated environmental impacts, and monitoring plans. The Secretary of Natural Resources is tasked with reviewing these projects and may impose additional monitoring or conditions as necessary. If any unforeseen environmental impacts arise during the project, the holder must suspend operations and notify the Secretary, who will then determine whether to allow the project to continue or terminate it. The act is set to take effect upon passage.
