Change of use. A nonconforming use of a structure, or premises and structure, may be changed to another nonconforming use; provided, that the proposed use is equally appropriate or more appropriate to the district than the existing nonconforming use.

C. 
Discontinuance. Any structure, or structure and land in combination, in or on which a nonconforming use is superseded by a permitted use, shall thereafter comply with the regulations for the district and the nonconforming use may not thereafter be resumed.
