If a residential facility, day program or other specialized service proposes to be funded by the department to provide services which the department provides through any of its facilities, programs or specialized services, the department shall determine how such services can most economically and effectively be provided and shall provide such services either directly or through contract and affiliation agreements, and shall avoid duplication of such services unless the department finds that such duplication is necessary. The department shall report any such duplication, and why the department deems such duplication necessary, in writing to the appropriations committees of the Missouri house and senate.
