(1)
Except as authorized by this section, the discharge of ballast water in the waters of this state is prohibited.(2)
An owner or operator of a vessel may discharge ballast water in the waters of this state:(a)
If the owner or operator has conducted a complete open sea or coastal exchange of ballast water prior to entering the waters of this state. The open sea or coastal exchange must be performed using either of the following methods:(A)
Flow-through exchange. A flow-through exchange occurs when an amount of ocean water equal to or exceeding three times the capacity of the vessel’s ballast tank is pumped into an opening in the ballast tank while the existing ballast water is discharged through another opening.(B)
An empty and refill exchange. An empty and refill exchange occurs when a ballast tank is pumped empty to the point that the pump loses suction and then is refilled with ocean water.(b)
Without performing an open sea exchange or a coastal exchange of ballast water if:(A)
Intentionally left blank —Ed.(i)
The owner or operator reasonably believes that an exchange would threaten the safety of the vessel; or(ii)
The exchange is not feasible due to vessel design limitations or equipment failure; and(B)
The vessel discharges only the amount of ballast water that is operationally necessary.(c)
If the ballast water is discharged in a manner consistent with standards and procedures adopted by the Environmental Quality Commission under subsection (4) of this section.(3)
An owner or operator who discharges ballast water in the waters of this state under subsection (2)(b) of this section is subject to the reporting requirements under ORS 783.640 (Reporting of ballast water management).(4)
Intentionally left blank —Ed.(a)
The Environmental Quality Commission may adopt by rule standards and procedures that the commission considers necessary to carry out the provisions of ORS 783.625 (Definitions for ORS 783.625 to 783.640) to 783.640 (Reporting of ballast water management). The standards and procedures must minimize the risk of introducing aquatic invasive species into the waters of this state and must be based on the availability of treatment technology. Rules adopted under this subsection include, but are not limited to:(A)
Standards for the discharge of ballast water into the waters of this state and appropriate timelines for the implementation of the standards. In adopting the standards, the commission shall consider the extent to which treatment technology is feasible, practicable and commercially available, or expected to be available, by the proposed implementation timelines.(B)
Emergency response procedures for managing high-risk ballast water. The rules must define high-risk ballast water in light of the source of the water and other applicable factors. The procedures must establish notification and consultation requirements, as well as feasible alternative ballast water management strategies.(C)
Procedures for implementing alternative ballast water management strategies for the exemptions specified in subsection (2)(b) of this section.(D)
Procedures for implementing alternative ballast water management strategies for vessels with empty ballast tanks that enter the waters of this state.(b)
To the extent practicable, the commission shall adopt rules under this subsection consistent with relevant rules adopted by the States of California and Washington. [2001 c.722 §3; 2005 c.62 §3; 2009 c.148 §1; 2015 c.704 §3]
