Washington Revised Code Title 70A. Environmental Health and Safety § 70A.515.130. Protection of certain records from public inspection

(1) Except as provided in subsection (3) of this section, records, subject to chapter 42.56 RCW, filed with the department from any person that contain valuable commercial information, including trade secrets, confidential marketing, cost, or financial information, or customer-specific usage information, are not subject to inspection or copying under chapter 42.56 RCW. When providing information to the department, a person shall designate which records or portions of records contain valuable commercial information.

(2) Upon receipt of a request to disclose valuable commercial information submitted under this chapter, the department must provide notice to the person or persons whose information is subject to possible inspection or copying under chapter 42.56 RCW.

(3) Upon the notice provided under subsection (2) of this section of the possible inspection or copying of valuable commercial information pursuant to chapter 42.56 RCW, a person may petition the superior court for an order protecting the records as confidential. The superior court must determine that the records are confidential and are not subject to inspection or copying if disclosure would result in private loss, including an unfair competitive disadvantage. If a person does not obtain an order protecting submitted records as confidential within ten days of receiving a notice from the department under subsection (2) of this section, the department may make the records available for public inspection and copying pursuant to chapter 42.56 RCW.
