About the Regional Offices
Northern Regional Office
The Northern Regional Office brings many services of the Indiana Department of Environmental Management to the citizens and communities of Northern Indiana. Serving the counties of DeKalb, Elkhart, Fulton, Kosciusko, LaGrange, Marshall, Noble, St. Joseph, Starke, and Steuben, the Northern Office helps to bring state environmental assistance from the state capital in Indianapolis to Northern Indiana residents, municipalities, counties, and planning districts.
Providing access to local permits, inspection reports, and general environmental information is but one of the areas of support that we bring to our region; local compliance and technical assistance to industries and groups starting to build, expand, or diversify their plants, and initiating and developing outreach services in environmental issues are among other services we provide.
In addition, staff of the Northern Regional Office answer questions from the public on a wide range of environmental subjects and represent the environmental community at important gatherings.
Northwest Regional Office
Some of the state's most serious environmental challenges lie in Lake, LaPorte and Porter counties in Northwest Indiana. A century of spills, emissions and discharges to the environment required government to respond with comprehensive, regionally coordinated programs. In 1991, IDEM opened a regional office in Gary to act as a liaison with local officials, concerned citizens, and industry, including the involvement of concerned citizens through the Citizen's Advisory for the Remediation of the Environment (CARE) Committee.
The Northwest Regional Office serves Lake, Porter and LaPorte Counties by providing local access to permits, inspection reports and general information on environmental activities with state, municipal, and industrial facilities. In addition, staff of the Northwest Regional Office answer questions from the public about a wide range of environmental subjects.
Southeast Regional Office
To better serve the southern portion of the state IDEM opened a Southeast Regional office in 2009. The Southeast Regional office serves the counties of Bartholomew, Brown, Clark, Crawford, Dearborn, Decatur, Fayette, Floyd, Franklin, Harrison, Jackson, Jefferson, Jennings, Lawrence, Monroe, Ohio, Orange, Perry, Ripley, Scott, Switzerland, Union, and Washington.
The Southeast Regional Office provides local access to permits, inspection reports and general information on environmental activities with State, municipal, and industrial facilities. In addition, staff of the Southeast Regional Office answer questions from the public on a wide range of environmental subjects and represents the environmental community at important gatherings.
Southwest Regional Office
The Southwest Regional Office serves the counties of Daviess, Dubois, Gibson, Knox, Martin, Pike, Posey, Spencer, Vanderburgh, and Warrick in southwest Indiana by providing a local access to permits, inspection reports and general information on environmental activities with State, municipal, and industrial facilities.
