360A WAC
On July 18, 2018, Ecology repealed existing Chapter 173-360 WAC        and adopted new Chapter
173-360A WAC, Underground Storage Tank (UST) Regulations. The new chapter modies and
replaces the repealed chapter. The rule was modied to:
1. Incorporate federal rule changes needed to maintain state program approval, as specied
in 40 C.F.R. Parts 280 and 281        (such as new operation and maintenance requirements
for UST systems and requirements for eld-constructed tanks and airport hydrant
systems).
2. Integrate changes to the state statute that authorizes the program, Chapter 90.76 RCW       
 (such as licensing requirements for UST systems).
3. Update other requirements governing the program (such as UST service provider
requirements).
4. Streamline rule requirements, improve rule clarity, and improve consistency within the rule
and with other state and federal laws and rules (such as reorganizing the rule).8/13/2018 Washington State Department of Ecology - W AC 173-360
