A.
General. Any industrial use permitted by right, by
special permit or by site plan approval in any district shall not
be conducted in a manner as to emit any dangerous, noxious, injurious
or otherwise objectionable fire, explosion, radioactivity or other
hazard; noise or vibration; smoke, dust, odor or other form of environmental
pollution; electrical or other disturbances; glare; liquid or solid
refuse or wastes; condition conducive to the breeding of insects or
rodents; or other substances, conditions or elements in an amount
as to affect adversely the surrounding environment.
B.
Standards.
(1)
Lighting. No direct or sky-reflected glare, whether
from floodlighting or high-temperature processes such as welding,
shall be hazardous or noxious. No outdoor lighting fixture shall produce
a strong, direct light beyond property boundaries of the facility
which the lighting fixture is servicing.
(2)
Noise.
(a)
The maximum permissible sound-pressure level
of any continuous, regular or frequent source of sound produced by
any use or activity shall not exceed the following limits at the property
line or the sound source:
|
Level Limits Measured in dBAs
| ||
|---|---|---|
|
Time
|
Source Pressure dBA Levels
| |
|
7:00 a.m. to 10:00 p.m.
|
70
| |
|
10:00 p.m. to 7:00 a.m.
|
60
| |
(b)
Sound pressure shall be measured at all major
lot lines at a height of at least four feet above the ground surface.
Noise shall be measured with a sound-level meter meeting the standards
of the American Standard Institute, ANSI SI.y-1961, American Standard
Specification for General Purpose Sound Level Meters. The instrument
shall be set on the A-weighted response scale. Measurements shall
be conducted in accordance with ANSI SI 51.2-1962, American Standard
Meter for the Physical Measurement of Sound.
(c)
Sound levels specified shall not be exceeded
for more than 15 minutes in any one day, except for temporary construction
or maintenance work, agricultural activity, timber harvesting, church
bells, emergency working devices or other similar special circumstance.
(d)
An intermittent, irregular or infrequent source
of sound shall be considered in violation of this chapter if the source:
[1]
Increases the broadband sound level by more
than 10 dBAs above ambient;
[2]
Produces a "puretone" condition. A "puretone"
condition exists when any octave band center frequency sound-pressure
level exceeds the two adjacent center frequency sound-pressure levels
by three decibels or more; or
[3]
Occurs between the hours of 10:00 p.m. and 7:00
a.m., except in emergency situations.
(3)
Stormwater runoff. The rate of surface water runoff from a site shall not be increased after construction. If needed to meet this requirement and to maximize groundwater recharge, increased runoff from impervious surfaces shall be recharged on site by being diverted to vegetated surfaces for infiltration or through the use of detention or retention ponds. Dry wells shall be used only where other methods are infeasible and shall require oil, grease and sediment traps to facilitate removal of contaminants. Stormwater runoff mitigation shall comply with § 270-29 of Chapter 270, Subdivision of Land, as amended.
(4)
Water quality. All outdoor storage facilities for
fuel, hazardous materials or wastes and potentially harmful raw materials
shall be located within an impervious diked containment area adequate
to hold the total volume of liquid kept within the storage area.
(5)
Explosive material.
(a)
No highly flammable or explosive liquids, solids
or gases shall be stored in bulk above ground unless they are located
in enclosed tanks at least 75 feet from any lot line, Town way or
interior roadway or 40 feet from any lot line for underground tanks,
plus all relevant state and federal requirements shall be met. Propane
gas tanks in one-hundred-pound cylinders (or smaller) shall be exempt
from these safety regulations.
(b)
All activities and all storage of flammable
and explosive materials at any point shall be provided with adequate
fire-fighting and fire-suppression devices and equipment.
(6)
Screening and buffer zones. Exposed storage areas,
exposed machinery installation, sand and gravel extraction operations
and areas used for the storage or collection of discarded automobiles,
auto parts, metal or any other articles of salvage or refuse shall
have sufficient setbacks and screening to provide a visual buffer
sufficient to minimize their adverse impact on surrounding properties
(e.g., dense evergreen hedge six feet or more in height). All such
planting shall be maintained as an effective visual screen; plants
which die shall be replaced within one growing season. Where a potential
safety hazard to children would be likely to arise, physical screening
sufficient to deter small children from entering the premises shall
be provided and maintained in good condition. A seventy-five-foot
buffer zone shall be provided along side and rear lot lines abutting
any residential or commercial property.
(7)
Emissions.
(a)
Emissions shall be completely and effectively
confined within the building or so regulated as to prevent any nuisance,
hazard or other disturbance from being perceptible (without the use
of instruments) at any lot line of the premises on which the use is
located.
(b)
No emission which can cause any damage or irritation
to the health of persons, animals or vegetation or which can cause
excessive soiling, at any point, shall be permitted.
(c)
No emission of odorous gases or odoriferous
matter in such quantities as to be offensive shall be permitted.
(d)
Activities that emit dangerous radioactivity
at any point shall be controlled in accordance with all regulations
of the Atomic Energy Commission.
(e)
No electrical disturbance adversely affecting
the operation, at any point, of any equipment, other than that of
the creator of such disturbance, shall be permitted.
(f)
No discharge, at any point, into a private sewerage
system, stream or the ground of any material in such a way or of such
a nature or temperature as may contaminate any running stream or water
supply or otherwise cause the emission of dangerous or objectionable
elements and accumulation of wastes conducive to the breeding of rodents
or insects shall be permitted.
The Building Inspector/Zoning Enforcement Officer
shall utilize specific standards and technical specifications and
shall be authorized to seek professional technical expertise from
the appropriate local, regional, state or federal agencies or individuals
having knowledge or an interest in the proposed use or potential impact
or disturbance.
