Section 49.70.165 - Trade secret exemptions(1) The department shall adopt rules in accordance with chapter 34.05 RCW establishing criteria for evaluating the validity of trade secret claims and procedures for issuing a trade secret exemption. Manufacturers or importers that make a trade secret claim to the department must notify direct purchasers if a trade secret claim has been made on a product being offered for sale.(2) If a trade secret claim exists, a manufacturer, importer, or employer may require a written statement of need or confidentiality agreement before the specific chemical identity of a hazardous substance is released. However, if a treating physician or nurse determines that a medical emergency exists and the specific chemical identity of a hazardous substance is necessary for emergency or first aid treatment, the manufacturer, importer, or employer shall immediately disclose the specific chemical identity to that treating physician or nurse, regardless of the existence of a written statement of need or a confidentiality agreement. The chemical manufacturer, importer, or employer may require a written statement of need and confidentiality agreement, as defined by rule, as soon as circumstances permit.(3) Any challenge to the denial of a trade secret claim shall be heard by an administrative law judge in accordance with chapter 34.05 RCW.
