The proposed bill establishes a comprehensive framework for mattress producer responsibility in Washington State, focusing on enhancing mattress recycling and reducing landfill waste. It requires mattress producers to join a producer responsibility organization (PRO) by January 1, 2026, and mandates registration with the Department of Ecology by July 1, 2026. The bill outlines specific requirements for PROs, including annual registration, financial accountability, and adherence to environmental management practices. Producers must be in good standing with a registered PRO by January 1, 2030, to continue selling mattresses in the state. Retailers are prohibited from selling mattresses unless the producer is part of an approved PRO and must inform customers about recycling options. Additionally, the bill introduces civil penalties for violations, with fines ranging from $1,000 for initial infractions to $10,000 for repeated offenses, and establishes a Responsible Mattress Management Account to manage funds from these penalties. It also grants immunity from certain antitrust laws for producers and organizations involved in mattress recycling programs. The bill amends various sections of the Revised Code of Washington (RCW) to include new provisions related to permits, penalties, and appeals concerning environmental regulations, specifically incorporating section 13 of this act into the jurisdiction of the department or air authority and ensuring that civil penalties now include section 13 of this act. Overall, the legislation aims to promote responsible mattress waste management while ensuring compliance and accountability.
