California State Lands Commission Validated Indicative Sampling Tools California State Lands Commission (CSLC) is working hard to be on the Solutions that safeguard front line of this ? ght and much work is being done on the state’s side. Out of the FUHZDQGSDVVHQJHUVroughly 10,000 ship arrivals at Califor-nia ports per year, typically 15% or 1,500 arrivals have intent to discharge ballast water. CSLC is mandated to board 25% of all ship arrivals. That means their ? eld staff is inspecting ~2,500 arrivals per year performing outreach, check-ing log books, verifying exchange loca-tions, etc. to ensure violations are at a minimum.
