This bill creates a new chapter in Title 70A RCW establishing microfiber filtration requirements for washing machines and amends statutes governing appeals and civil penalty procedures. It prohibits the sale or offer for sale in Washington of new commercial or industrial washing machines manufactured on or after July 1, 2028 unless the machine contains or is equipped with a microfiber filtration system and bears a conspicuous operator/consumer notice about the filter. Owners or operators of commercial or industrial machines not subject to the sale restriction must equip those machines with a functioning microfiber filtration system by July 1, 2034, and must ensure filters are checked, remain functional, and captured lint is disposed of in a solid waste container. The bill defines terms including commercial, industrial, residential washing machine, microfiber (less than five millimeters), and sets technical standards for a “microfiber filtration system” (active across all cycles, mesh size 100 micrometers or less, independent third‑party certification of at least 87% removal, and either built in or packaged as an in‑line system). It authorizes the Department of Ecology to adopt implementing rules, to issue corrective action orders for violations of the filtration requirement, and to adopt a rule after July 1, 2030 that may require new residential machines to be capable of filtering microfibers if specified market and cost conditions are met; any residential rule may not take effect sooner than 365 days after adoption. The bill creates or modifies enforcement and penalty procedures: civil penalties of up to $5,000 per violation for a first offense and up to $10,000 per violation for repeat offenses are authorized, penalties and orders are appealable to the pollution control hearings board, and all penalties collected under the chapter are to be deposited in the model toxics control operating account (RCW 70A.305.180). It reenacts and amends RCW 43.21B.110 to include the new section among decisions appealable to the hearings board and reenacts and amends RCW 43.21B.300 to specify procedures for imposing civil penalties, timelines for appeals and payment, collection actions in superior court, and directions for where recovered penalties are deposited; the text also lists multiple affected agencies and accounts. The provided document appears incomplete: the reenactment/amendment text for RCW 43.21B.110 is cut off, RCW 43.21B.300 and other referenced sections are not fully shown, sections 1–4 are referenced but not all are present, and in some places the specific identity of “the department” or certain authorities is not defined in the extracted text.

If enacted, manufacturers and sellers will need to offer only new commercial and industrial washers that include a certified microfiber filter and a prominent operator label starting July 1, 2028, and owners/operators of existing commercial or industrial machines will have until July 1, 2034 to equip those machines with functioning filters and keep them checked and lint disposed in solid waste containers. The Department of Ecology gains new authority to make rules, enforce requirements, issue corrective orders, and levy civil penalties (up to $5,000 for a first offense, $10,000 for repeats), with collected penalties deposited into the model toxics control operating account and appealable to the pollution control hearings board; the department may also later require residential machines to be capable of filtering if market and cost conditions warrant, but any such rule could not be started before July 1, 2030 and would take at least a year after adoption to take effect. Manufacturers and sellers face likely design, testing, certification, labeling and compliance costs and may need to change product lines offered in Washington; owners and operators of multifamily, commercial laundry, and business laundries face costs to buy and install filters or replace machines, plus ongoing labor for checking and disposing of captured lint and the risk of civil penalties if they fail to comply. The Department of Ecology will have added rulemaking and enforcement responsibilities, and the pollution control hearings board will hear appeals; the bill text provided is incomplete on some procedural details and on how residential requirements would be triggered, so the exact timing and scope of those later obligations remain unclear.
