shall emit any liquid or solid particles in concentrations exceeding
0.3 grain per cubic foot of the conveying gas nor any color visible
smoke equal to or darker than No. 2 on the Ringlemann Chart described
in the United States Bureau of Mines' Information Circular 7718 in

All activities involving the manufacturing, utilization, processing,
or storage of inflammable and explosive materials shall be provided
with adequate safety devices against the hazard of fire and explosion
and with adequate fire-fighting and fire-suppression equipment and

exterior walls and an automatic fire-extinguishing system.

The maximum light trespass allowed on adjacent properties is 0.5
footcandle onto residential property and 2.0 footcandles for nonresidential

B.
All exterior light sources shall be fully shielded, meaning that
all light emitted by the fixture, either directly from the lamp or
a diffusing element, or indirectly by reflection or refraction from
any part of the luminaire, is projected below the horizontal as determined

C.
Any operation producing intense glare or heat, such as combustion
or welding, shall be performed within a completely enclosed building
in such a manner as not to create a public nuisance or hazard across

No activity shall discharge at any point onto any land or into
any water or public sewer any materials of such nature, quantity,
noxiousness, toxicity, or temperature that they can contaminate, pollute,

a.m. or after 9:00 p.m., except in cases of emergency work.
There shall be no vibrations emanating from any operation which
