Establishes Office of River Maintenance in DEP; repeals P.L.1993, c.376 concerning stream cleaning activities.

S 422 establishes a new Office of River Maintenance within New Jersey's Department of Environmental Protection (DEP) to oversee stream cleaning, debris removal, and bank stabilization projects. This office replaces the previous system under P.L.1993, c.376, and must follow specific rules to protect water quality - such as preserving historic stream contours, avoiding harm to sensitive habitats, and coordinating with agencies for endangered species or protected waters. The bill repeals the 1993 law to centralize these responsibilities under the new office, ensuring projects comply with existing environmental regulations.
