Therefore, in addition to the applicable provisions of other general regulations of this chapter, the following specific regulations shall apply:
(1) 
Each use permitted in the district shall be conducted within a completely enclosed building, provided that outdoor storage may be allowed in conjunction with a permitted use if the area used for storage is located or screened so as not to be visible from an adjoining property line.
(2) 
The area surrounding each permitted building shall be suitably and attractively landscaped, and each building shall be designed so as to minimize its traditional industrial appearance and shall, insofar as is practicable, afford minimum external evidence of the nature of the operation conducted therein.
(3) 
All equipment shall be operated by electric power, oil, gas or other smokeless fuel, and each use shall provide and utilize such smoke-, odor-, dust-, noise- or other control devices as are necessary to assure that the use will not constitute an objectionable condition as defined in § 139-97.
(4) 
No products or goods shall be publicly displayed on the premises.
(5) 
Adequate provision shall be made for water supply, sewage and waste disposal. Where public water and sewer facilities are not used, such facilities shall be approved by the Township or other appropriate governmental agency.
(6) 
Along any rear or side property line which abuts a residence district or Township boundary line, a buffer yard shall be provided which shall be not less than 100 feet in width, except when the zoning district in the adjoining Township permits substantially similar uses. This required yard shall be measured from the boundary line or from the street line where a street constitutes the boundary. The 30 feet of such yard space nearest the district or Township boundary line shall be used only as a buffer planting strip, as defined in § 139-6. The remaining 70 feet of space may be used for off-street parking or for any permitted purpose other than a building or permanent structure or any processing activity.
(7) 
Where necessary, adequate provisions shall be made to supplement public fire-fighting facilities.
(8) 
Each use shall comply with the provisions of §§ 139-98, 139-99 and 139-100 relating to parking, loading and the development of highway frontage. All required parking, except that intended for use by visitors, shall be located in the side or rear yard.
