Section 18.78.230. Initial abatement.

Unless directed in writing by the department to do otherwise, after meeting the requirements of 18 AAC 78.220, the owner or operator of a UST with a confirmed release of petroleum shall perform the following abatement and containment measures:  
		(1) cease using the system and, if not already performed under 18 AAC 78.220(c)(2), within seven days remove the petroleum from the UST to prevent further release of petroleum to the environment; the UST may not be refilled until the system is repaired, replaced, or upgraded so that a further release cannot occur;  
		(2) visually inspect any aboveground release or exposed belowground release and prevent further migration of petroleum into surrounding soils and groundwater;  
		(3) continue to monitor and mitigate any additional fire and safety hazards posed by vapors of free product that have migrated from the UST excavation zone and entered into subsurface structures, including basements, sewers, and utility lines; and  
		(4) properly stockpile excavated contaminated soils to prevent water run-on and run-off in accordance with 18 AAC 78.274 and remedy a hazard posed by contaminated soils that are excavated or exposed in response to a release confirmation, site characterization, site assessment, abatement, or corrective action; if these remedies include treatment, stockpiling, or disposal of contaminated soils, the owner or operator shall use a method that the department determines will adequately protect human health and safety, and the environment.
