The Washington State Department of Ecology proposes to repeal existing Chapter 173-360 WAC and adopt new Chapter 173-360A WAC, Underground Storage Tank (UST) Regulations. As part the rulemaking, Ecology proposes to:
• Incorporate federal rule changes needed to maintain state program approval, as specified in 40 CFR Parts 280 and 281 and adopted in June 2015.
• Incorporate changes to the state’s UST program specified in the authorizing state statute, Chapter 90.76 RCW.
• Make other selective changes to the requirements governing the state’s UST program (such as updating UST service provider requirements).
• Streamline rule requirements, improve rule clarity, and improve consistency within the rule and with other state and federal laws and rules.
