Authorizes performance of supplemental environmental project to replace portion of monetary penalties for environmental violations in certain circumstances.

This bill allows businesses or individuals who violate New Jersey environmental laws to replace part of their fine with a supplemental environmental project (SEP) that reduces pollution. The Department of Environmental Protection must approve the project proposal, which must detail the work, costs, and environmental benefits. The SEP can cover up to 75% of the penalty (50% for water pollution violations), but participation is voluntary and requires department approval based on factors like community impact and project feasibility. The bill aims to direct funds toward actual environmental improvements rather than solely collecting fines.
