The purpose of this district is to require that no changes in use or new development occur on Point Hennepin until all necessary federal, state, and local environmental studies and clearances are completed. Point Hennepin is a fill area built up over a period of years by the distribution of disposal materials from chemical manufacturing operations on the nearby mainland.

This district permits only the presently existing unused chemical disposal site on Hennepin Island. Reactivation of chemical disposal functions, further development, or changes in land use may be permitted only upon application to the Township. An agreement between the BASF Corporation and Grosse Ile Township executed on September 26, 1977, provides for the filling of existing Point Hennepin brine field sinkholes with dredging spoils, demolition rubble and similar inert material (containing no toxic matter, refuse, garbage, rubbish, or ashes) in accordance with State of Michigan Department of Natural Resources permit standards and Wayne County Health Department environmental health standards.

The Grosse Ile Township Planning Commission must be consulted with respect to any proposed changes in land use on Point Hennepin or any physical changes involving the present use of the land. The Planning Commission, in consultation with requisite Wayne County, State of Michigan, and federal agencies, shall inform the applicant of all required environmental and development studies, analyses, clearances, approvals, and permits.
