The Architectural Paint Stewardship Act requires producers of architectural paint in New Jersey to either implement or participate in a statewide paint stewardship program designed to facilitate the environmentally responsible disposal of post-consumer paint. Producers must develop and submit a comprehensive stewardship plan to the Commissioner of Environmental Protection within one year of the bill's enactment. This plan should ensure convenient collection of leftover paint, minimize public sector involvement, and include educational outreach to inform consumers about disposal options. Additionally, a paint stewardship assessment must be included in the sale price of architectural paint to fund the program.

The legislation prohibits the sale of architectural paint by producers, distributors, and retailers who are not part of an approved stewardship program and outlines penalties for non-compliance, including warnings and fines. The Department of Environmental Protection is responsible for overseeing the program's implementation, approving plans, and enforcing compliance. The bill also provides antitrust liability protections for participating producers and organizations, with certain exceptions, and establishes a maximum annual penalty for violations. The provisions of the bill will take effect immediately, with specific sections enforceable 18 months after enactment.
