California Code, Health and Safety Code - HSC § 25142.5

The department shall develop and implement a comprehensive training, education, and enforcement program for generators, transporters, and facility operators, for personnel conducting inspections for the departments, and for certified unified program agencies. The program shall be designed to increase awareness of the requirements governing the determination of whether a waste is hazardous, including, but not limited to, the requirements governing the use of the generator's knowledge of a waste to determine if the waste is hazardous, and to enhance the level of enforcement of those requirements. In implementing this program, the department shall give priority to training, education, and enforcement activities relating to the classification of the particular waste streams that the department determines are the most susceptible to misclassification, including, but not limited to, oily water and contaminated soil.
