California State Lands Commission: The SLC was established in 1938 with authority detailed in Division 6 of the California Public Resources Code (PRC). The staff of the SLC serves the people of California by providing stewardship of the lands, waterways, and resources entrusted to its care through economic development, protection, preservation, and restoration. The following PRC articles were established by the SLC to facilitate the discharging of ballast water and hull maintenance in California waters.
Article 4.6 – Ballast Water Regulations for Vessels Arriving at California Ports or Places after Departing from Ports or Places within the Pacific Coast Region: The purpose of Article 4.6(CCR Title 2, Division3, Chapter 1) is to move the state toward elimination of the discharge of non-indigenous species into the waters of the state. Under Article 4.6, the operator in charge of a vessel that arrives at a California port (i.e. POLB, POLA) shall employ at least one of the following ballast water management practices:
Exchange the vessel's ballast water in near-coastal waters, before entering the waters of the state, if that ballast water has been taken on in a port or place within the Pacific Coast region.
Retain all ballast water on board the vessel.
Use an alternative, environmentally sound method of ballast water management that, before the vessel begins the voyage, has been approved by the commission or the United States Coast Guard as being at least as effective as exchange, using mid-ocean waters, in removing or killing non-indigenous species.
Discharge the ballast water to a reception facility approved by the commission.
Under extraordinary circumstances where compliance with subsections (a)(1) through (a)(4) of this section is not practicable, perform a ballast water exchange within an area agreed to by the commission in consultation with the United States Coast Guard at or before the time of the request.
Article 4.7 – Performance Standards for the Discharge of Ballast Water for Vessels Operating in California Waters: The purpose of Article 4.7 (CCR Title 2, Division3, Chapter 1) is to move the state toward elimination of the discharge of non-indigenous species into the waters of the state. Subject to the implementation schedules identified in Section 2294 of Article 4.7, before discharging ballast water in waters subject to the jurisdiction of California, the operator, or person in charge of a vessel to which this section applies, shall conduct ballast water treatment so that ballast water discharged will contain:
No detectable living organisms that are greater than 50 micrometers in minimum dimension;
Less than 0.01 living organisms per milliliter that are less than 50 micrometers in minimum dimension and more than 10 micrometers in minimum dimension;
For living organisms that are less than 10 micrometers in minimum dimension:
a. less than 1,000 bacteria per 100 milliliters;
b. less than 10,000 viruses per 100 milliliters;
c. concentrations of microbes that are less than:
i. 126 colony forming units per 100 milliliters of Escherichia coli;
ii. 33 colony forming units per 100 milliliters of Intestinal enterococci;
iii. 1 colony forming unit per 100 milliliters or 1 colony forming unit per gram of wet weight of zoological samples of Toxicogenic Vibrio cholerae (serotypes 01 and 0139).
Implementation schedule as follows:
Beginning January 1, 2010, for vessels constructed on or after that date with a ballast water capacity of less than or equal to 5,000 metric tons.
Beginning January 1, 2012, for vessels constructed on or after that date with a ballast water capacity greater than 5,000 metric tons.
Beginning January 1, 2014, for vessels constructed before January 1, 2010, with a ballast water capacity of 1,500 metric tons or more but not more than 5,000 metric tons.
Beginning January 1, 2016, for vessels constructed before January 1, 2010, with a ballast water capacity of less than 1,500 metric tons, and for vessels constructed before January 1, 2012, with a ballast water capacity greater than 5,000 metric tons.
Article 4.8 – The Collection of Information Relating to Hull Husbandry Practices of Vessels for Control of Marine Invasive Species in Waters of California: Article 4.8 (CCR Title 2, Division3, Chapter 1) requires the owner or person in charge of a vessel carrying, or capable of carrying, ballast water into the coastal waters of the state to file the “Hull Husbandry Reporting Form” developed by the SLC, providing information regarding the hull husbandry practices relating to the vessel, within 60 days of receiving a written or electronic request from the SLC.
