FUHZDQGSDVVHQJHUV roughly 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. CLSC is taking advantage of
