Division 8 — PERFORMANCE STANDARDS

All uses established or placed into operation after the effective date of this chapter shall comply at all times hereafter with the following performance standards. All commercial and industrial uses actually established and in operation on the effective date of this chapter shall be made to comply with the following performance standards on or before the effective date of this chapter and shall comply at all times thereafter.

(Ord. No. 24-03, § 2, 9-17-24)

All new residential construction shall comply with the noise insulation standards of title 24, part 2 of the California Code of Regulations.

(Ord. No. 24-03, § 2, 9-17-24)

(a)

Fire and explosion hazards. The city fire prevention code shall apply to all developments and uses in the city.

(b)

Electrical disturbance. Except where rules of the Federal Communications Commission take precedence, devices that radiate radio-frequency energy shall be so operated as not to cause interference with any activity carried on beyond the boundary line of the property upon which the device is located. Radiofrequency energy is defined as electromagnetic energy at any frequency in the radio spectrum between ten (10) kilocycles and three million (3,000,000) megacycles.

(c)

Noise. The maximum one (1) hour average sound level radiated by any use or facility when measured at any point at least four (4) feet above ground level, on or beyond the boundary line of the property on which sound is generated, shall not exceed the following:

*Zone which exists on the abutting or nearby property at whose boundary the measurement is taken.

(d)

Vibration. Every use shall be so operated that the ground vibration inherently and recurrently generated does not cause a displacement of the earth greater than three thousandths (0.003) of one (1) inch as measured at any point along the property line of the use.

(e)

Smoke. No emission of visible grey smoke shall be permitted at any point, from any chimney or otherwise, when of a shade equal to or darker than:

(1)

Units No. 1 and No. 2 on the Power's Micro-Ringlemann chart. Emissions of such smoke are permitted for a maximum of four (4) minutes in any thirty (30) minute period. These provisions are also applicable to visible smoke of a different color but with an apparently equivalent opacity.

(f)

Emission of dust, heat and glare. Every use shall be so operated that it does not emit dust, heat or glare in such a quantity or degree as to be readily detectable on any boundary line of the lot on which the use is located. The following requirements also apply:

(1)

Dust, dirt and fly ash shall not exceed three tenths (0.3) grains per cubic feet of flue gas at stack temperature of five hundred (500) degrees Fahrenheit, nor fifty (50) percent excess air. In addition, such emissions shall in no manner be unclean, destructive, unhealthful, hazardous, nor shall visibility be impaired by emission of a haze in which vision is unduly impeded with an apparent opaqueness equivalent to Unit No. 1 of the Power's Micro-Ringlemann chart.

(2)

Glare from arc welding, acetylene torch cutting or similar processes shall be performed so as not to be seen from any point outside of the property.

(g)

Emission of odors. No emission of odorous gases or other odorous matter in quantities which exceed the proportions shown in the Imperial County Air District's Rules and Regulations manual as periodically updated.

(1)

Odor. The emission of obnoxious odors of any kind shall not be permitted.

(2)

Gas. No gas which is deleterious to the public health, safety or general welfare shall be emitted. (Ord. No. 24-03, § 2, 9-17-24)
