Establishes registration and training program for commercial applicators of substances for snow and ice removal.

New Jersey bill A3694 establishes a voluntary registration and training program for commercial applicators who remove snow or ice for hire using deicing substances. It requires these applicators to complete certified training on effective, water-quality-protective methods and register with the Department of Environmental Protection (DEP). The program mandates record-keeping of application methods and amounts, annual reporting to DEP, and periodic refresher training. Registered applicators gain limited liability protection for snow/ice removal on private property when following trained methods, but this protection does not apply if they act recklessly or deviate from the training. The bill directly affects commercial snow/ice removal businesses and property owners who hire them, aiming to reduce water contamination from excessive deicer runoff.
