The Mission of the WDEP is to develop and implement a tribal environmental program that will encourage productive and enjoyable harmony between human beings and their environment; to promote efforts that will prevent or eliminate damage to natural resources and the environment; and to enrich the understanding of the ecological systems and natural resources important to the Wichita and Affiliated Tribes.

Initiated in 1995, the Wichita Department of Environmental Programs (WDEP) began its operations in response to identified environmental problems. These problems included illegal dumpsites and water pollution. With assistance from the Environmental Protection Agency (EPA), the WDEP has expanded its environmental services with the addition of the following programs: EPA General Assistance Program (GAP) and the EPA Clean Water Act Section 106 Program.

General Assistance Program



EPA provides funding for the General Assistance Program (GAP). Staff initiates activities in order to provide Wichita and Affiliated Tribes' members with information regarding the GAP's objective to identify Wichita tribal properties containing illegal dumpsites. All identified sites will be mapped using GIS software and GPS equipment. WDEP will work with landowners to gain access to the tribal properties for the mapping procedure. WDEP will then report all identified open dumps to Indian Health Service for inclusion on the OM SDS Database for possible future cleanup. An application asks for the types of items on the property; the checklist consists of Household Trash, Paint Cans, Containers of Chemicals, Lumber, Chemical Spills,;Tires, Metal/Wire, and Appliances.

WDEP is currently trying to locate additional illegal dumpsites for possible future clean-up. These dumpsites must be located on tribal allotted trust property to be eligible for most funding. WDEP welcomes reports on any illegal dumpsites, as well as any other possible environmental concerns to this office whether they are on or near tribal lands.
