Description: In light of concerns about the Department of Toxic Substances Control’s execution of its responsibilities in recent years, the Legislature has held numerous hearings to monitor the performance of the department’s programs. The Legislature has also approved additional funding and positions for the department to address deficiencies in some of these programs. In this web post, we discuss the department’s progress to date in addressing these deficiencies, as well as provide questions for legislators to ask the department in future budget and policy hearings to determine the degree to which the department is improving program performance.
