The Mississippi Department of Environmental Quality (MDEQ) is committed to providing public access to environmental information. Our agency believes that keeping citizens informed enhances achievement of our goal of environmental protection.

The Department's continuing investment in information technology facilitates its mission of environmental stewardship. enSearch Online provides a comprehensive view of MDEQ's regulated community (agency interests) and their activities, by allowing the public access to information about permitting and compliance activities within the scope of MDEQ.

The information contained in enSearch Online 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, Waste 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 and Waste Tire Program; Geology Surface Mining and Reclamation Division; (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 Surface Water Division’s Total Maximum Daily Load (TMDL) Program.
