Which entity is responsible for collecting delinquent payments from licensees?

The Central Collection Unit is responsible for collecting delinquent payments from licensees in the context of Maryland law. This unit operates as part of the state's efforts to ensure compliance with financial obligations, particularly regarding various licenses and permits. The Central Collection Unit specializes in managing debt collection for state agencies, which includes tracking down delinquent accounts and working to recover owed funds. This function is essential in maintaining fiscal responsibility and accountability among licensees.

Other entities listed, such as local law enforcement, the Board of Health, and the Department of Education, have specific roles and jurisdictions, but they do not engage in the collection of delinquent payments related to licensees. Local law enforcement focuses on law enforcement activities and maintaining public safety, the Board of Health primarily oversees public health regulations and services, and the Department of Education deals with educational institutions and policies. Therefore, the unique role of the Central Collection Unit positions it as the correct answer for this question.
