(1)

COMPLIANCE. This Ordinance permits specific uses in specific districts; and these performance standards are designed to limit, restrict, and prohibit the effects of those uses outside their premises or district. No structure, land, or water shall hereafter be used except in compliance with their district regulations and with the following performance standards.

(2)

SOUND. The volume of sound inherently and recurrently generated shall not exceed the following standards at any point along the boundaries of the zone in which the use is located:

(a)

Objectionable sounds of an intermittent nature shall be controlled so as not to become a nuisance to adjacent uses; and

(b)

Maximum sound pressure levels shall be measured with a sound level meter and associated octave band analyzer conforming to standards prescribed by the American Standards Association and shall not exceed the values for octave bands lying within the several frequency limits given in the following table after the application of appropriate corrections:

B-1, B-2, B-3, B-4, B-5, AND B-6 DISTRICTS

M-1 AND M-2 DISTRICTS

(3)

VIBRATION. An operation which creates vibrations that can be measured without instruments, e.g. heavy drop forges, heavy hydraulic surges, shall be set back:

(a)

In all B Districts, a distance of not less than 500 feet from all lot lines except where a lot line abuts an M District in which case no setback is required; and

(b)

In an M District, a distance of not less than 500 feet from the district boundaries.

(4)

RADIOACTIVITY. No operation shall be permitted which causes radioactivity in violation of Title 10, Chapter 1, Part 20, Code of Federal Regulations, "Standards for Protection Against Radiation," dated June 16, 1957, or any subsequent revisions or amendments.

(5)

ODOR. In A, C and all B Districts, no emission of odorous gas or other odorous matter in such quantity as to be readily detectable at any point along lot lines without use of instruments shall be permitted. In an M District, no emission of odorous gas or other odorous matter in such quantity as to be readily detectable at any point along district boundaries without use of instruments and in such quantity as to produce a public nuisance or hazard beyond lot lines shall be permitted.

(6)

TOXIC OR NOXIOUS MATTER. No discharge beyond lot lines of any toxic or noxious matter in such quantity as to be detrimental to or endanger the public health, safety, comfort, or welfare, or cause injury or damage to property or business, shall be permitted.

(7)

GLARE. No direct or reflected glare from any M District shall be detectable from any R District boundary.

(8)

HEAT. No direct or reflected heat from any M District shall be detectable from any R or B District boundaries.

(9)

DUST. No solid or liquid particles shall be emitted in concentrations exceeding 0.3 grains per cubic food of the conveying gas or air.

(10)

FLY ASH. No emission of fly ash in excess of the quantity specified in the following table shall be permitted:

For heat content between any 2 consecutive heat contents given in the table, the fly ash limitation shall be as determined by interpolation.

(11)

SMOKE. No emission of smoke from any source, as measured on the Ringelmann Chart published by the United States Bureau of Mines, shall be permitted in excess of:

(a)

In all B Districts, a density described as Ringelmann No. 2, provided that a density equal to Ringelmann No. 3 may be emitted for not more than 3 minutes in any 15 consecutive minutes; and

(b)

In all M Districts, a density described as Ringelmann No. 3.
