The bill mandates that public agencies in Washington State must provide clear notice for public comment periods, specifically including the first and last date and time by which written comments can be submitted. This requirement applies to agencies that are already obligated by state law to solicit public comments for a designated period.

Additionally, the bill establishes penalties for agencies that fail to comply with this notice requirement, subjecting them to the same fines and procedures as other violations under the existing public agency laws. This new section is added to chapter 42.30 RCW, enhancing transparency and accountability in the public comment process.
