The bill establishes a Paint Product Stewardship Program in New Hampshire, which aims to manage postconsumer paint products through environmentally responsible practices. It introduces new definitions related to paint products, such as "aerosol coating product," "architectural paint," and "postconsumer paint," which are inserted into RSA 149-M. Manufacturers or their representative organizations are required to submit a stewardship plan detailing the management of paint products, including collection sites, funding mechanisms, and educational outreach. The plan must also specify the fees associated with paint products sold in the state, which will be added to the purchase price and remitted to the representative organization. Furthermore, the bill prohibits manufacturers and retailers from selling paint products in New Hampshire unless they are part of an approved stewardship program.

Additionally, the bill mandates that collection sites cannot charge extra fees for managing paint and that the per-container fee must be included in the sale price of paint products. It requires manufacturers to submit an annual report to the Department of Environmental Services, detailing the volume of paint sold and recovered, collection methods, stewardship program costs, and an independent financial audit. The Department of Environmental Services will oversee the program, including rulemaking and regulatory enforcement, with administrative costs covered by fees from manufacturers. The program is set to be implemented within six months of approval, with an expected start date of July 1, 2025, and aims to reduce local expenditures on waste paint management by at least $150,000 annually starting in FY 2027.
