Sound levels shall be measured with a sound-level meter and associated octave-band filter manufactured according to standards prescribed by the American Standards Association. Measurements shall be made using the flat network of the sound-level meter.

Exceptions. The maximum permissible sound levels by the receiving land use category as listed in the previous table shall not apply to any of the following noise sources:

No industrial operation or activity shall cause at any time and at any point along the nearest adjacent lot line ground-transmitted vibrations in excess of the limits set forth below. Vibration (the periodic displacement, measured in inches, of earth) shall be measured with a three-component measuring instrument and shall be expressed as displacement in inches.

Exceptions. The following uses and activities shall be exempt from the vibration level regulations:

No flammable or explosive liquids, solids or gases shall be stored in bulk above the ground, except for tanks or drums of fuel directly connecting with energy devices, heating devices or appliances located and operated on the same lot as the tanks or drums of fuel.

All outdoor storage facilities for fuel, raw materials and products stored outdoors, including those permitted in the above subsection, shall be enclosed by a fence of a type, construction and size as shall be adequate to protect and conceal the facilities from any adjacent properties. Fencing shall not only encompass the question of safety but also of screening, and the screening shall preferably be evergreens. All National Occupational Safety and Health Administration regulations shall be met.

No materials or wastes shall be deposited upon a lot in such form or manner that they may be transported off by natural causes or forces, nor shall any substance which can contaminate a stream or watercourse or otherwise render such stream or watercourse undesirable as a source of water supply or recreation or which will destroy aquatic life be allowed to enter any stream or watercourse. Applicable Department of Environmental Protection regulations shall apply.

All materials or wastes which might cause fumes or dust or which constitute a fire hazard or which may be edible or otherwise attractive to rodents or insects shall be stored outdoors only if enclosed in containers adequate to eliminate such hazards. Applicable County Department of Health and National Occupational Safety and Health Administration regulations shall apply.

There shall be no discharge of any toxic substance, gasoline, benzene, naphtha, fuel, oil or other flammable or explosive liquid, solid or gas, any liquid having a temperature higher than 150° F. or any matter containing any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, paunch manure or any solid or viscous substance capable of causing obstruction in or other interference with the proper operation of a sewage treatment plant or any liquid having a pH lower than 5.0 or higher than 9.0 or having any other corrosive property capable of causing damage or hazard to structures, equipment or personnel or material which would be harmful to the treatment of sewage.

Acidity and alkalinity of wastes shall be neutralized with a pH of 7.0 as a daily average on a volumetric basis, with a temporary variation of a pH of 5.0 to 9.0.

Wastes shall contain no cyanides and no halogens and shall not contain more than 10 parts per million of the following gases: hydrogen sulfide, sulfur dioxide and nitrogen dioxide.

Wastes shall not contain any insoluble substances in excess of 10,000 parts per million nor exceed a daily average of 500 parts per million nor fail to pass a No. 8 sieve nor have a dimension greater than 0.25 inch.

Wastes shall not have:

Dust, dirt, smoke, vapor, gas, odor, glare and heat control.

Light, glare and heat control. No use shall carry on an operation that will produce light, heat or glare perceptible beyond the property line of the lot on which the operation is situated.
