2/8/1993, § 47; and by Ord. 98-6, 6/22/1998, § 10]
1.
The sound level of any operation (other than the operation of motor
vehicles or other ground transportation facilities on public highways;
operations involved in the construction or demolition of structures
between 6:00 a.m. and 10:00 p.m.; emergency alarm signals or time
signals) shall not exceed the decibel levels in the designated octave
bands as stated below. The sound-pressure level shall be measured
with a sound level meter and octave band analyzer that conform to
specifications published by the American National Standards Institute.
American National Standard Specification for Sound Level Meters, S1.4-1971,
American National Standards Institute, Inc., New York, New York, and
the American Standard Specification for an Octave, Half Octave and
Third Octave Band Filter Sets, S1.11-1966, R 1971, American National
Standards Institute, Inc., New York, New York, shall be used.
2.
Sound-pressure levels shall be measured at the property line upon
which the emission occurs. The maximum permissible sound-pressure
levels for smooth and continuous noise shall be as follows. (All of
the decibel levels stated below shall apply in each case). These standards
shall apply to the expansion of nonconforming uses as well as uses
conforming to the use regulations for the applicable district.

10/13/1997, § 27-1502]
1.
No smoke or other source of visible gray opacity greater than No.
1 on the Ringlemann Smoke Chart as published by the U.S. Bureau of
Mines shall be emitted from any chimney, except that smoke of a shade
not darker than No. 2 on the Ringlemann Chart may be emitted for not
more than four minutes in any thirty-minute period.
2.
Nothing in this chapter shall preclude the burning of domestic trash
on the premises of any detached dwelling. This domestic trash shall
be limited to that generated on the premises and shall be limited
to a quantity normally generated by one family.
3.
Open burning by any nonresidential or any other residential use shall
be prohibited except when such burning is at least 1,000 feet from
any property line and 1,000 feet from any office, industrial plant
or other structure in which people reside, are employed or otherwise
gather.
4.
All burning, except as specified above, shall be regulated by 25
Pa.Code, Chapter 129, Standards for Sources, as amended, of the Pennsylvania
Department of Environmental Protection.
5.
No open burning shall take place on a lot of less than 25,000 square
feet. Permitted burning shall take place only between sunrise and
sunset and shall be contained and attended.
[Ord. 3/29/1990A, § 1402]
1.
The emission of dust, dirt, fly ash, fumes, vapors or gases which
can cause any damage to human health, to animals, to vegetation or
to property, or which can cause any soiling or staining of persons
or property at any point beyond the lot line of the use creating the
emission, is herewith prohibited.
2.
No emission of liquid or solid particles from any chimney or other
source shall exceed 0.3 grains per cubic foot of the carrying gas
at any point beyond the lot line of the use creating the emission.
For measurement of the amount of particles in gases resulting from
combustion, standard correction shall be applied to a stack temperature
of 500° F. and 50% excess air in stack at full load.
[Ord. 3/29/1990A, § 1403]
No use shall produce heat perceptible beyond its lot lines.
[Ord. 3/29/1990A, § 1404]
1.
No use shall emit odorous gases or other odorous matter in such quantities
as to be offensive at any point on or beyond its lot lines. The guide
for determining such quantities of offensive odors shall be the 50%
response level of Table 1 (Odor Thresholds in Air), "Research on Chemical
Odors: Part 1-Odor Thresholds for 53 Commercial Chemicals," October,
1968, Manufacturing Chemists Association Inc., Washington, D.C.
2.
Subsection .1, above shall not apply to odors normally created as
part of an agricultural or horticultural use except that no animal
waste produced off of the property shall be stockpiled unless processed
to eliminate all offensive odors.
3.
Exhaust fans shall not be directed toward the street, parking area
or other areas where people pass or gather.

No use shall produce a strong, dazzling light or a reflection
of a strong, dazzling light beyond its lot lines. In general, lighting
fixtures that shield the reflector or lens or any high brightness
surface from viewing angles above 60° from horizontal shall be
utilized. Glare shall be defined as direct or indirect light of greater
than 1/2 footcandle at the property line or above a plane level with
the top of the light fixture. Lighting facilities shall be provided
and arranged in a manner which will not cause adverse effects upon
the highway and any properties from glare. A lighting plan shall be
submitted and shall be subject to review and approval by the Township
Engineer.
[Ord. 3/29/1990A, § 1406]
1.
No use shall cause earth vibrations or concussions in excess of the
standards outlined below, with the exception of vibration produced
as a result of construction activity. The standards below are as set
forth in the Table of Frequency Amplitude Relations. Vibration shall
be expressed as displacement in inches and shall be measured with
a standard three component measuring system, which is a device for
recording the intensity of any vibration in three mutually perpendicular
directions.

the quantities of cubic feet at standard temperature and pressure
permitted shall not exceed 30 times the quantities listed above.
B.
Except for storage facilities or single-family dwellings and uses
regulated by agencies of the commonwealth, all outdoor above ground
storage facilities for fuel, raw materials and products, and all fuel,
raw materials and products stored outdoors, shall be enclosed by a
fence with a minimum height of eight feet. Such fence shall be chain
link, stockade, picket (not exceeding three-inch spacing), solid wood,
building wall or other such material as may be acceptable to the Zoning
Officer to carry out the intent of this chapter.

life, be allowed to enter any stream or watercourse. Disposal of sewage,
septage or sludge must meet the requirements of the Pennsylvania Department
of Environmental Protection.
D.
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

[Ord. 3/29/1990A, § 1411]
All nonresidential uses or activities shall submit a solid waste
disposal plan which specifically identifies areas of compliance with
the New Hanover Township Solid Waste Management Plan and Recycling
Plan.
