Webinar on California Biofouling Management Regulations: First Year Update
The Marine Invasive Species Program presented a webinar in October 2018 to provide an update on the implementation of California’s biofouling management regulations. The webinar specifically focuses on improving clarity for specific requirements that have been commonly deficient during inspections during the first year of implementation.
