(a)

Any use, building, structure, or land developed, constructed or used for any permitted principal use, or any use permissible as a special exception, or any accessory use, shall comply with all of the performance standards herein set forth.

(b)

If any existing use or building or other structure is extended, enlarged, or reconstructed, the performance standards involved shall apply with respect to such extended, enlarged, or reconstructed portion or portions of such use, building, or other structure.

(c)

Within 24 months of the adoption of this chapter, all existing uses, buildings, or other structures shall comply with the performance standards herein set forth, provided, however, that if the planning and zoning board finds that because of the nature of the corrective action required, the 24-month period is inadequate, it may, as a special exception, grant not more than one exception for a period of not more than 12 months.

(Code 1966, § 45-106; Ord. No. 4-1973, § I, 3-7-1973; Code 1978, § 32-163)

All uses within the town shall conform to the performance standards set forth herein.

(1)

Smoke and particulate matter standards.

a.

Requirements. The amount of particulate matter resulting from smoke or other sources permitted in ambient air shall not exceed 200 milligrams per cubic meter during any 24-hour period of continuous measurement.

b.

Method of measurement. The amount of particulate matter present in ambient air shall be measured by a high-volume sampler, capable of pulling approximately 30 to 50 cubic feet of air per minute through a pre-weighed filter, and approved for use by the Florida State Board of Health, Bureau of Sanitary Engineering.

c.

Locational requirements for measurement. The amount of particulate matter shall be measured at the property line of the use from which such particulate matter is emitted.

d.

Density and prevention of smoke emissions. In the event that a high-volume sampler is not available to the town, every use shall be so operated as to prevent the emission of smoke from any source whatever, to a density greater than described as Number 1 on the Ringelmann Smoke Chart, provided, however, that smoke equal to but not in excess of that shade of appearance described as Number 2 on the Ringelmann Chart may be emitted for a period or periods totaling four minutes in any 30 minutes. For the purpose of grading the density of smoke, the Ringelmann Chart, as published and used by the United States Bureau of Mines, and which is hereby made, by reference, a part of these regulations, shall be the standard. All measurements shall be at the point of emission for this period of measurement.

(2)

Odor standards.

a.

Requirements. All uses shall be controlled to prevent the emission of odorous gases or other matter in such quantities as to be objectionable or offensive at the specified points of measurement.

b.

Method of measurement. A noxious concentration shall be deemed to be the point at which the threshold of smell can be achieved.

c.

Locational requirement. Noxious odors shall be measured as specified at a point 25 feet from the point of origin.

(3)

Toxic gases, fumes, vapors and matter.

a.

Generally. All uses shall be controlled to prevent the discharge of any toxic gases or matter in such quantity that may endanger the public health, safety or welfare or cause damage or injury to other property or uses.

b.

Locational requirement. Measurement shall be made at point of discharge into the atmosphere.

(4)

Vibration standards.

a.

Requirements. All uses shall be controlled to prevent the transmission of any vibration, from any source or at any time whatever, that exceeds the maximum displacement set forth in subsection (4)d of this section.

b.

Method of measurement. The displacement of earth caused by vibration shall be measured in inches by an appropriate instrument approved by the town commission upon recommendation of the town engineer.

c.

Location requirement. Vibration shall be measured as specified along the boundaries of the site.

d.

Permitted vibration transmissions.

(5)

Glare and lighting standards. Any lighting elements or structural materials installed on a site shall be prevented from casting or reflecting glare or light beyond the boundaries of the site, unless their location precludes any hazard or nuisance arising as a consequence of such glare or light. Locations requiring some means of preventing the transmission of glare or light beyond the site's boundaries are established according to the relationship between: Required minimum elevation of the lighting element or structural material above the final grade established along the nearest site boundary, and distance of the lighting element or structural material from the nearest boundary. As set forth in the following table, elements or materials below the minimum elevation required of each distance shall be shielded or otherwise screened to prevent transmission of light or glare beyond the site:

(6)

Electromagnetic radiation; requirements. All uses shall be controlled to prevent any source of electromagnetic radiation which does not comply with the current regulations of the Federal Communications Commission regarding such sources of electromagnetic radiation.

(7)

Heat and humidity. Any use producing humidity in the form of steam or moist air, or producing heat, shall be carried on in such a manner that steam, humidity or heat is not perceptible to the average person using his normal senses at any lot line.

(8)

Fire and explosion. Each use shall be so operated as to minimize the danger from fire and explosion and to comply with the fire regulations.

(9)

Radiation hazards. Applicable standards of the Florida State Board of Health Sanitary Code are hereby adopted.
