All uses and activities established after the effective date of this chapter shall comply with the following standards.
Standards for open space and environmental factors shall be as follows:
A. 
Open waterways. No open waterways shall be developed or filled without the approval of the Pennsylvania Department of Environmental Protection.
B. 
Alluvial soils. In areas not covered by floodplain studies, no alluvial soils as defined by Interim Soil Survey Report, Volume I and II, Soil Conservation Service, 1970, shall be developed or filled.
C. 
Steep slopes. In areas of steep slopes, that is, slopes above 8%, not more than 40% of such areas shall be developed and/or regraded.
D. 
Forests. Areas of forest or mature stands of trees are to be left intact where possible. In any event, no more than 40% of such areas may be developed and/or cleared.
E. 
Lakes, ponds or marshes. They shall be left intact. No development, filling, piping or diverting shall be permitted, except with the approval of the Borough Engineer.
F. 
Stormwater. All developments shall limit stormwater runoff so that no more runoff is generated than that of the site in its natural condition. All runoff calculations shall be based on a one-hundred-year, twenty-four-hour storm. The method for such calculations shall be that contained in United States Department of Agriculture, Soil Conservation Engineering Field Manual, Notice 4 of April 30, 1971, as amended.
G. 
Soil erosion and sedimentation. All developments shall protect streams, lakes and ponds from sedimentation and shall control erosion in accordance with the Clean Streams Law, P.L. 1987, Chapter 102,[1] except that, in addition, all developments shall submit an erosion control plan as part of the preliminary land development plan.

Editor's Note: See 35 P.S. § 891.1 et seq.
A. 
Noise.
(1) 
Other than the operation of motor vehicles or other transportation facilities, operations involved in the construction or demolition of structures, emergency alarm signals or time signals, the sound level of any operation 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 an octave band analyzer that conform to specifications published by the American Standards Association. [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 Standards Association, 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:
Frequency Band
(cycles per second)
Maximum Permitted Sound-Pressure Level
(decibels)
0 to 150
67
150 to 300
59
300 to 600
52
600 to 1200
46
1,200 to 2,400
40
2,400 to 4,800
34
Above 4,800
32
(3) 
If the noise is not smooth and continuous or is radiated during sleeping hours, one or more of the corrections below shall be added to or subtracted from each of the decibel levels given above.
Type of Operation or Character of Noise
Corrections in Decibels
Noise occurs between the hours of 10:00 p.m. and 7:00 a.m.
-3
Noise occurs less than 5% of any one-hour period
+5
Noise is of periodic character (hum, scream, etc.) or is of impulsive character (hammering, etc.). (In the case of impulsive noise, the correction shall apply only to the average pressure during an impulse, and impulse peaks shall not exceed the basic standards given above.)
-5
B. 
Smoke. No smoke shall be emitted from any chimney or other source of visible gray opacity greater than No. 1 on the Ringelmann Smoke Chart as published by the United States Bureau of Mines, except that smoke of a shade not darker than No. 2 on the Ringelmann Chart may be emitted for not more than four minutes in any thirty-minute period.
C. 
Dust, fumes, vapors and gases.
(1) 
The emission of dust, dirt, fly ash, fumes, vapors or gases which can cause any damage to human health, to animals or vegetation or to other forms of 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 covering 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.
D. 
Heat. No use shall produce heat perceptible beyond its lot lines.
E. 
Odor. 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 fifty-percent-response level of Table I, Odor Thresholds in Air, Research on Chemical Odors: Part I — Odor Thresholds for 53 Commercial Chemicals, October, 1968, Manufacturing Chemists Association, Inc., Washington, D.C.
F. 
Glare. No use shall produce a strong, dazzling light or a reflection of a strong, dazzling light beyond its lot lines.
G. 
Vibrations. No use shall cause earth vibrations or concussions detectable beyond its lot lines without the aid of instruments, with the exception of that vibration produced as a result of construction activity.
H. 
Buffer yards. Buffer yards are required in all SC Service Commercial, RC Retail Commercial, MB Metropolitan Business, I Industrial Districts and TOD Transit-Oriented Development along the district boundaries between themselves and residential districts, and for MB Metropolitan Business Districts, between it and any other district. No service commercial, retail commercial, metropolitan business or industrial uses shall hereafter be established, nor shall existing uses be expanded, unless they meet the following buffer yard regulations:

(5) 
No structure, parking, manufacturing or processing activity or storage of materials shall be permitted in the buffer yard.
(6) 
All buffer yards shall include a dense screen planting of trees and shrubs or other plant materials, or both, to the full length of the lot line to serve as a barrier to visibility, airborne particles, glare and noise. Such screen planting shall be in accordance with the following requirements:
(a) 
Plant materials used in the screen planting shall be at least four feet in height when planted and be of such species as will produce, within two years, a complete visual screen of at least eight feet in height.

No materials or wastes shall be deposited upon a lot in such form or manner that they may be transferred off the lot by natural causes or forces, nor shall any substance which can contaminate a stream or watercourse or otherwise render such stream or watercourse undesirable as a source of water supply or recreation, or which will destroy aquatic life, be allowed to enter any stream or watercourse.
(4) 
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 containers adequate to eliminate such hazards.
