(a) The building must have four (4) walls complete and be provided with concrete or cement floors and with good drainage and be thoroughly sanitary in construction and maintenance. Any sewage, drainage, or waste water of any kind, if of an offensive or obnoxious character or odor, detrimental to human, animal, agricultural or aquatic life, shall not be permitted to escape therefrom until first treated as herein specified. All sewage and plant wastes shall be disposed of according to recognized and accepted sanitary engineering methods which will not create a public health hazard or unsanitary situation so as to be a nuisance.

(b) All such plants must be properly equipped and operated with steel tanks, enclosed dryers and cold water condensers. All tanks shall be airtight except proper escapes for live steam, passing through the tanks during cooking, which steam shall be condensed by use of cold water condensers. All such equipment and any other equipment which may be invented, manufactured and installed for use in disposal or rendering plants shall be so constructed and maintained as to prevent any avoidable escape of odors into the air.

(c) All skinning and dismembering of bodies shall be done within such building and in such manner and shall be so kept therein that no unnecessary annoyance shall be caused other persons by the conditions or unsightly appearance of such bodies or any parts and contents thereof, and all such bodies and all parts and contents thereof shall be disposed of within twenty-four (24) hours after delivery to such plant, by some method herein specified, except where rendered impossible by accident or other casualty preventing the operation of the plant, or except where some epidemic or act of God has caused more bodies to be accumulated than can be reasonably disposed of within such period of time by the continuous operation of the plant. In such events the plant shall be placed in operation as soon as possible and shall be operated continuously until all bodies are disposed of.

(d) Such disposal plant shall be so situated, constructed and maintained and all operations therein so conducted at all times as not to create and continue unnecessarily a public nuisance.
