No salvage yard shall be operated or maintained inside the Municipality without a license and no license shall be granted a person who maintains a salvage yard inside the Municipality within one thousand feet of any primary or interstate highway. If a salvage yard is operated or maintained within three hundred feet of any secondary highway the view thereof from such highway shall be obscured by natural objects or a fence as herein defined; provided, however, that a person who was maintaining or operating a salvage yard prior to January 1, 1959, inside the Municipality shall be granted a license if his salvage yard is operated or maintained adjoining any primary, interstate or secondary highway right of way and the view from such highway is obscured by natural objects, plantings or a fence on his property line as herein defined; provided further, that the provisions hereof shall not be construed to permit any person who operated or maintained a salvage yard prior to January 1, 1959, to enlarge, expand or increase the size of said salvage yard.
