Cross reference— Licenses and business regulations, ch. 8.

Sec. 19-336. - Regulation standards for industrial processes.#

Industrial operations, shall be located only in those districts permitted in section 19-98. Industrial operations and processes, shall not exceed the standards of performance as established in this section and required by this chapter.

(Rev. Ords. 1987, § 19-336; Ch. 453, § X, 7-15-08)

Sec. 19-337. - Smoke.#

No emission at any point from any chimney or otherwise of visible gray smoke of a shade darker than No. 2 on the Ringelmann Smoke Chart, as published by the U.S. Bureau of Mines in August, 1955, as information circular 7718 (revision of i.c. 6888), is permitted, except that visible smoke of a shade darker than No. 2 on such chart may be emitted for not more than four minutes in any 30 minutes in a C-5 district or in an I-1 or I-2 district and not more than eight minutes in any 30 minutes in an I-3 district. These provisions applicable to visible gray smoke shall also apply to visible smoke of a different color, excluding steam and other nontoxic emissions, but with an equivalent apparent opacity.

(Rev. Ords. 1987, § 19-337)

Sec. 19-338. - Dust and other particulate matter.#

Any handling, transfer or storage of materials shall use best available technology to control fugitive emissions of dust or other particulate matter from migrating to off-site locations in any amount which is injurious to human health, animals, vegetation or other forms of property or which causes any excessive soiling at any point beyond the property lines. Such technology may include dust collection/suppression systems, wind guards and spraying of stockpiles with surfactants.

(Rev. Ords. 1987, § 19-338)

Sec. 19-339. - Odor.#

No emission of odorous gases or other odorous matter in such quantities as are offensive outside the industry property shall be permitted. No odorous emission shall be permitted which is determined to be obnoxious or which unduly transfers with or prevents the comfortable enjoyment of life or property.

(Rev. Ords. 1987, § 19-339)

Sec. 19-340. - Gases; fumes.#

Industrial use shall not emit noxious, toxic or corrosive fumes or gases in concentrations or amounts causing unreasonable discomfort or injury to humans or harm to vegetation. When acceptable air quality criteria are developed by the U.S. public health service, these standards shall be considered for adoption in this section.

(Rev. Ords. 1987, § 19-340)

Sec. 19-341. - Noise.#

(a)

Noise shall be measured from the nearest property line in a commercial 5 district or an industrial 1 or 2 district or floating zone district and from the nearest industrial 3 district boundary line in an industrial 3 district. At the specified points of measurement, the sound pressure level of noise radiated continuously from an industrial operation or plant other than background noises produced by non-industrial sources such as vehicular traffic or other transportation shall not exceed the values given in Table I of section 10-53 in octave bands of frequency. 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 standard sound level meters for measurement of noise and other sounds, S1.4-1961, and American standard specification for an octave band filter set for the analysis of noise and other sounds, Z24.10-1963, American Standards Association, Inc., New York, New York, shall be used.

(b)

The maximum permissible sound-pressure levels at specified points of measurement for noise radiated continuously from a facility shall conform with the values in subsection 10-53(c)(2).

(c)

The aforementioned limits are intended for normal continuous day-to-day operations. A variance to exceed these limits by a reasonable amount may be granted for temporary and shortterm operations during construction, maintenance or emergency conditions.

(Rev. Ords. 1987, § 19-341; Ch. 453, § XI, 7-15-08)

Sec. 19-342. - Vibration.#

(a)

Vibration shall be measured from the nearest property line in a C-5 district or an I-1 or I-2 district and from the nearest I-3 district boundary line in an I-3 district.

(b)

No vibration is permitted which is discernible to the human sense of feeling for three minutes or more duration in any hour of the day between 7:00 a.m. and 7:00 p.m. or of 30 seconds or more duration in any one hour between 7:00 p.m. and 7:00 a.m. No vibration at any time shall produce an acceleration of more than 0.1g or shall result in any combination of amplitudes and frequencies beyond the safe range of Table 7, U.S. Bureau of Mines Bulletin No. 442, Seismic Effects of Quarry Blasting, on any structure. The methods and equations of such bulletin shall be used to compute all values for enforcement of this regulation.

(Rev. Ords. 1987, § 19-342)

Sec. 19-343. - Heat and glare.#

No industrial use shall carry on any operation that would produce heat or glare beyond the property line in a C-5 district or an I-1 or I-2 district or beyond the I-3 district boundary line in an I-3 district. No industrial activity shall use industrial and exterior lighting in a manner that produces glare on property highways or neighboring property.

(Rev. Ords. 1987, § 19-343)

Sec. 19-344. - Industrial sewage and waste.#

(a)

Industrial sewage and waste may be deposited in a public sewage system when available. Such wastes, if adequately treated by a private treatment plant, may be disposed into other than a public sewage system provided that:

(1)

A septic tank, tile field or other disposal place for any waste shall be located at least 50 feet from the nearest point of any river, pond, swampy area or district boundary of a residential district or 1,000 feet from any drinking water source or supply unless the water is adequately treated and chlorinated to be satisfactory for such use or unless evidence is given to show that geologically it is not possible for the waste to migrate into or contaminate any drinking water supply;

(2)

No effluent shall contain any acids, oils, dust, toxic metals or corrosive or other toxic substances in concentrations which would create obnoxious odors or discolor, poison or otherwise pollute any stream or watershed adversely.

(b)

Wherever feasible, process or cooling waters shall be recirculated and reused.

(Rev. Ords. 1987, § 19-344)

Sec. 19-345. - Radiation.#

Industrial operations shall cause no dangerous radiation at the property line as specified by the regulations of the Nuclear Regulatory Commission.

(Rev. Ords. 1987, § 19-345)
