Chapter 9-407 — Performance Standards

9-407.010 - PURPOSE AND APPLICABILITY

(a)

Purpose. The purpose of this Chapter is to establish performance standards to mitigate dangerous or objectionable environmental impacts of commercial and industrial uses, pursuant to the health and safety policies of the General Plan.

(b)

Applicability. These performance standards shall apply to all commercial and industrial uses in the County, except as otherwise provided herein.

9-407.020 - AIR QUALITY

All emissions of air pollutants shall be subject to the rules and regulations of the San Joaquin Valley Unified Air Pollution Control District.

9-407.030 - ELECTRICAL DISTURBANCES

(a)

Uses involving electromagnetic forces shall not cause electrical disturbances which adversely affect individuals or the operation of any equipment beyond any lot line of the lot containing such uses.

(b)

The disclosure of potential health effects associated with electromagnetic fields and PCB-contaminated electrical equipment shall be required for residential development projects.

9-407.040 - HEAT, HUMIDITY, AND COLD

Heat, humidity, or cold emanating from any use shall not be able to be felt by any reasonable person at any lot line of the lot containing such use.

9-407.050 - ODOR

All uses shall be so operated as not to cause odors that are perceptible and offensive to any reasonable person at any residential lot line. Odor control systems shall be provided to control odors.

9-407.060 - VIBRATION

(a)

Perceptible Vibration. No use shall cause any perceptible vibration at any lot line abutting any zone except within an I-G zone.

(b)

Vibration Within the General Industrial Zone. Vibration along any lot line within an I-G Zone shall not exceed the levels for vibration displacement set forth in Table 9-405.060. Vibration displacement shall be measured by a seismograph or other instrument capable of measuring and recording displacement and frequency, particle velocity, or acceleration. Readings shall be made at points of maximum vibration along any lot line within an I-G Zone.

(c)

Exceptions. The limits of this Section shall not apply to the construction or demolition of structures or infrastructure or to vibration caused by motor vehicles or trains.
