Our mission is to protect and promote the physical and environmental health of the citizens and state employees of Delaware from asbestos, underground storage tanks, and indoor air quality. We strive to prevent unnecessary exposure of the public to asbestos and poor indoor air quality in workplaces and State-owned buildings. Through the Outreach Program, we educate the public to gain voluntary compliance with state and federal environmental law. We carry out our mission efficiently, effectively, fairly and professionally with respect and dedication to all contractors and their employees who must be licensed by our agency.
