The information contained in this report is obtained from MDEQ's enSite (electronic environmental Site Information System) System used by the Office of Pollution Control's Air Division, Environmental Permits Division and Environmental Compliance and Enforcement Division, and the Office of Geology's Mining and Reclamation Division. The purpose of the system is to support permitting and compliance activities of the Department of Environmental Quality. Regulatory programs that are supported by this database are the Surface Water National Pollutant Discharge Elimination System (NPDES) Program; the Air Title V, Construction and Operating Programs; the Solid and Hazardous Waste Programs; Geology Surface Mining and Reclamation Division; and the Waste Tire Program (the UST program is currently not supported). There are other regulatory programs within the Department that do not currently utilize this database including programs managed by the Office of Land and Water, and the Total Maximum Daily Load (TMDL) Program.
