[Ord. No. 4190, 2-1-2021]
A. 
This Article is intended to protect public health and safety by requiring that all uses shall be construed, maintained and operated so as to not be injurious or offensive to the occupants of adjacent premises by reason of the emission or creation of noise, vibration, smoke, dirt or other particulate matter, toxic or noxious waste materials, odors, fire and explosive hazard or glare.
B. 
The standards of this Article shall apply to any new or existing use.
C. 
If, at such time, the operations of any lawful existing use violate the standards of this Article, such violation shall be rectified immediately.
[Ord. No. 4190, 2-1-2021]
A. 
Whenever, in the opinion of the Community Development Director, there is a reasonable probability that any use of occupancy violates these standards, the Community Development Director is hereby authorized to employ a qualified technician or technicians to perform whatever investigations and analyses are necessary to determine whether or not they are in fact being violated.
B. 
In the event that a violation is found to exist, the violator shall be liable for the reasonable fee for retaining technicians to perform such investigations and analyses.
C. 
Any violation of this Article shall hereby be considered as creating a public nuisance and therefore, in addition to the enforcement procedures specified in this Article, the regulations of the Municipal Code governing nuisances and any other applicable Sections of this Code shall apply.

Noise.[1]
1. 
Every use shall be so operated that the pressure level of sound or noise generated, measured in decibels, shall not exceed, at any point on the lot line, the maximum decibel levels for the designated octave band as set forth in Table 425.620.B, Maximum Permitted Decibel Levels, below, for the appropriate area:

Editor’s Note: As to additional noise regulations, Section 215.750 of this Code.
C. 
Vibration.
1. 
A use shall be so operated that ground vibration inherently and recurrently generated is not perceptible without instruments at any point on the property line of the property on which the use is located.
D. 
Dust, Dirt And Other Matter.
1. 
Every use and site operation, such as construction or grading, shall be so operated as to prevent the emission into the air of dust, dirt, noxious acids, fumes, gases and other particulate matter, whatever its source, which may cause damage to property and health of persons at or beyond the lot line of the property on which the use is located.
2. 
The air quality standards and air pollution control regulations consisting of Title 10, Division 10, Chapters 5 and 6, of the Missouri Code of State Regulations, as adopted and promulgated by the Air Conservation Commission of the State of Missouri for the St. Louis Metropolitan Area shall apply.
E. 
Smoke And Particulate Matter.
1. 
No operation or use in the City of Lake Saint Louis shall cause, create or allow the emission for more than three (3) minutes in any one (1) hour of air contaminants which at the emission point or within the property are:
a. 
As dark or darker in shade as that designated as No. 2 on the Ringelmann Chart as published by the United States Bureau of Mines Information Circular 7118.
b. 
Of such opacity as to obscure an observer's view to a degree equal to or greater than does smoke or contaminants in the standard prescribed in Subsection (E)(1)(a) except that when the presence of uncombined water is the only reason for failure to comply or when such contaminants are emitted inside a building which prevents their escape into the outside atmosphere, the standards in Subsections (E)(1)(a) and (E)(1)(b) shall not apply.
c. 
The emission of particulate matter from all sources shall not exceed one-half (1/2) pound per acre of property within the plant site per any one (1) hour.
d. 
Allowable open storage and open processing operations, including on-site transportation movements, shall be so conducted that dust and other particulate matter so generated are not transported across the boundary line of the tract on which the use is located in concentrations exceeding four (4) grains per one thousand (1,000) cubic feet of air.
e. 
Applicable standards and enforcement provisions contained in the Lake Saint Louis City Code covering fire safety shall apply.
f. 
Every use shall be so operated as to prevent the emission of objectionable or offensive odors in such concentration as to be readily perceptible at any point at or beyond the lot line of the property on which the use is located.
g. 
Every use shall be so operated that there is no dangerous amount of radioactive emissions in accordance with the standards of the Federal Radiation Council.
h. 
Any operation producing intense glare or heat shall be performed in an enclosure in such a manner as to be imperceptible along any lot line without instruments.
