Article 11-1115-1117-Performance Standards for Industrial UsersSECTION 1115 PERFORMANCE STANDARDS FOR INDUSTRIAL USES
These performance standards shall apply as minimum standards in those districts where compliance
with said standards is required.
1115.01 LIMITED INDUSTRIAL PERFORMANCE STANDARDS: To be a permitted industrial
use in ML Light Industrial and Manufacturing District, whether as a permitted use or as an exception,
such use must meet the following performance standards:
(1) Physical Appearance: All operations shall be carried on within an enclosed building except that
new materials or equipment in operable condition may be stored in the open. Normal daily wastes
of an inorganic nature may be stored in containers not in a building when such containers are not
readily visible from the street.
(2) Fire Hazard: No operation shall involve the use of flammable gasses, acid, liquids, grinding
processes, or other inherent fire hazard, except that such operation shall be allowed for such
flammable gases, acids, liquids, grinding processes, or other inherent fire hazards if same are
contained, stored, utilized, processed, or restricted to a building or structure, or area or portion of
same that is so constructed as to be explosion proof. No part of this section shall be construed as to
prohibit the use of normal heating fuels, motor fuels, and welding gasses when handled in
accordance with other City regulations. Notwithstanding any other provision herein, such
flammable gasses, acids, liquids, and fuels may be stored outside of an explosion proof building or
structure so long as they are not located within 600 feet of a residential structure and further
providing same are stored in full compliance with all Nebraska State Fire Marshall Rules and
Regulations.
(3) Sewage and Liquid Wastes: No operation shall be carried on which involves the discharge into a
sewer, water course or the ground of liquid wastes of any radioactive nature, or liquid wastes of a
chemical nature which are detrimental to normal sewage plant operation or corrosive and damaging
to sewer pipes and installations.
(4) Air Contaminants: Air contaminants and smoke shall be less dark than designated Number One
on the Ringleman Chart as published by the United States Bureau of Mines, except that smoke of a
density designed as Number One shall be permitted for one (1) four (4) minute period in each
one-half (1/2) hour. Light colored contaminants of such an opacity as to obscure an observer's view
to a degree equal to or greater than the aforesaid shall not be permitted.
Particulate matter of dust as measured at the point of emission by any generally accepted method
shall not be emitted in excess of two-tenths (.2) grains per cubic foot as corrected to a temperature
of five hundred (500) degrees Fahrenheit, except for a period of four (4) minutes in any one-half
(1/2) hour, at which time it may equal but not exceed six-tenths (.6) grains per cubic foot as
corrected to a temperature of five hundred (500) degrees Fahrenheit.
Due to the fact that the possibilities of air contamination cannot reasonably be comprehensively
covered in this section there shall be applied the general rule that there shall not be discharged from
City of Blair Zoning Regulations Article 11, Sections 1115-1117, page 1
any sources whatsoever such quantities of air contaminants or other material in such quantity as to
cause injury, detriment, nuisance or annoyance to any considerable number of persons or to the public
in general or to endanger the comfort, repose, health or safety of any such considerable number of
persons or to the public in general or to cause or have a natural tendency to cause injury or damage to
business, vegetation or property.
(5) Odor: The emissions of odors that are generally agreed to be obnoxious to any considerable
number of persons, shall be prohibited. Observations of odor shall be made at the property line of the
establishment causing the odor. As a guide to classification of odor it shall be deemed that strong
odors of putrefaction and fermentation tend to be obnoxious and that such odors as associated with
baking or the roasting of nuts and coffee shall not normally be considered obnoxious within the
meaning of this Ordinance.
(6) Gasses: The gasses sulfur dioxide, hydrogen sulfide and carbon monoxide shall not exceed five
(5) parts per million. All nitrous fumes shall not exceed (1) part per million. Measurements shall be
taken at the property line of the particular establishment involved.
(7) Vibration: All machines including punch presses and stamping machines shall be so mounted as
to minimize vibration and in no case shall such vibration exceed a displacement of three thousandths
(3/1000) of an inch measured at the property line. The use of steam or broad hammers shall not be
permitted.
(8) Glare and Heat: All glare, such as welding arcs and open furnaces, shall be shielded so that they
shall not be visible from the property line. No heat from furnaces or processing equipment shall be
sensed at the property line to the extent of raising the temperature of air or materials more than five
(5) degrees Fahrenheit.
(9) All EPA and DEQ standards pertaining to noise shall be met.
1115.02 INDUSTRIAL PERFORMANCE STANDARDS: To be a permitted industrial use in the
HL Heavy Industrial and Manufacturing District, whether as a permitted use or an exception, such
use must meet the following performance standards;
(1) Appearance: Junk, salvage, auto wrecking and similar operations shall be shielded from view
from streets and from adjacent properties in another district by means of a sturdy, sight-obscuring
fence in good repair, or two rows of alternate planted evergreen trees.
(2) Fire Hazard: All flammable substances involved in any activity established in the district shall be
handled in conformance with the Life Safety Code published by the National Fire Protection
Association. All elements of SECTION 7 of the Blair Code shall be complied with.
(3) Sewage and Liquid Waste: No operation shall be carried on which involves the discharge into a
sewer, water course or the ground of liquid wastes of any radioactive nature, or liquid waste of a
chemical nature which are detrimental to normal sewage plant operation or corrosive and damaging to
sewer pipes and installations.
City of Blair Zoning Regulations Article 11, Sections 1115-1117, page 2
(4) Air Contaminants: Air contaminants and smoke shall be less dark than designated Number One
on the Ringleman Chart as published by the United States Bureau of Mines, except that smoke of a
density designated as Number Two shall be permitted for an aggregate ten (10) minute period in each
one-half (1/2) hour. Light colored contaminants of such opacity as to obscure an observer's view to a
degree equal to or greater than the aforesaid shall not be permitted. Particulate matter or dust as
measured at the point of emission by any generally accepted method shall not be emitted in excess of
two-tenths (.2) grains per cubic foot as corrected to a temperature of five hundred (500) degrees
Fahrenheit, except for a period of four (4) minutes in any one-half (1/2) hour, at which time it may
equal but not exceed six-tenths (.6) grains per cubic foot as corrected to a temperature of five
hundred (500) degrees Fahrenheit.
Due to the fact that the possibilities of air contaminants cannot be comprehensively covered in this
section there shall be applied the general rule that there shall not be discharged from any source
whatsoever such quantities of air contaminants or other material in such quantity as to cause injury,
detriment, nuisance or annoyance to any considerable number of persons or to the public in general or
to endanger the comfort, repose, health or safety of any such considerable number of persons or the
general public or to cause or have a natural tendency to cause injury or damage to business,
vegetation or property.
(5) Odor: Odor causing operations shall be controlled so as to reduce escape of odors to the
minimum practical within the limits of technology and economics.
(6) Gasses: All noxious gasses shall be controlled to the extent that they will not be injurious to life
and property. The gasses sulfur dioxide and hydrogen sulfide shall not exceed five (5) parts per
million, carbon monoxide shall not exceed twenty-five (25) parts per million, and nitrous fumes shall
not exceed five (5) parts per million. All measurements shall be made at the property line.
(7) Vibration: All machines including punch presses and stamping machines shall be mounted so as
to minimize vibration. Vibration shall not be so excessive that it interferes with industrial operations
on nearby lots.
(8) All EPA and DEQ standards pertaining to noise shall be met.
