Dunnellon City Zoning Code

ARTICLE XIII

OPERATIONAL PERFORMANCE STANDARDS

Section 13.1 - Application.

All uses established or changed and any building, structure or tract of land developed, constructed or used in any industrial district shall comply with all of the performance standards set forth for the district involved. Any change, addition or reconstruction of a building or use shall meet these requirements for the addition, reconstruction, or enlargement.

Section 13.2 - Methods for measurement.

In order to determine compliance with the requirements relating to noise, odor, smoke, etc., standard instruments which have been accepted by the particular industry involved shall be used. Listed in section 13.3 are the instruments and manuals which shall be used, except that suitable substitutes as determined by the Community Development Manager may also be used. The initials listed before the particular instruments or manuals in section 13.3 are symbols which will be used elsewhere in these regulations. The manuals, codes, and description of measuring devices in the standards below are hereby adopted by reference as if the works appeared in this code in their entirety. The most recent amendment or revision of each code or manual shall be used.

Section 13.3 - Standard manuals and measuring devices.

(a)

The following devices and instruments standardized by the American Standards Association shall be used:

OBF Octave band filter
SLM Sound level meter
INF Impact noise filter manufactured by General Radio Company
VMD Three-component vibration measuring device
ADI Atmospheric dust impinger

 

(b)

One of the following devices or its equivalent for measuring cup flashpoints shall be used:

Pensky-Martens.

Tagliabue.

(c)

The following charts and manuals are hereby adopted by reference:

BMI 6888 The Ringelmann Chart described in U.S. Bureau of Mines Information Circular 6888.
APAM "Air Pollution Abatement Manual" of the Manufacturing Chemist Association.
PHR47 U.S. Public Health Report 47, No. 12, "Measurement of Density of Mineral Dusts."
ICR12 Industrial Code Rule No. 12 adopted by the Board of Standards and Appeals of the New York State Department of Labor.
CFR10 Title 10, chapter 1, part 20, Code of Federal Regulations, "Standards for Protection Against Radiation."

 

Section 13.4 - Noise.

For the purpose of measuring the intensity and frequency of sound the SLM and OBF shall be used. In the enforcement of this regulation, noises produced by the operation of motor vehicles or other transportation facilities shall not be included in determining the maximum permitted decibel levels. Sounds of short duration such as from forge hammers and punch presses shall be measured with the INF. For sounds so measured the maximum sound pressure level set forth in the table may be increased by six decibels.

Decibels resulting from any activity, whether open or enclosed, shall not exceed, at any point on or beyond any lot line, the maximum level set forth in the table below. Maximum levels at any point abutting a residential district boundary shall be reduced by six decibels from the maximum listed.

MAXIMUM PERMITTED SOUND PRESSURE LEVEL IN DECIBELS

Octave Band
(cycles per second)
Sound Pressure Level
(decibels)
0—74 79
75—149 74
150—299 66
300—599 59
600—1,199 53
1,200—2,399 47
2,400—4,799 41
4,800 and over 39

 

State Law reference— Motor vehicle noise, F.S. §§ 316.393, 403.415.

Section 13.5 - Vibration.

No activity shall cause or create a steady state or impact vibration on a lot line or on a boundary line between the land use creating the vibration and a residential district with a vibration displacement by frequency bands in excess of that indicated in the table below as measured by the VMD.

No activity shall cause or create a steady state or impact vibration on a district boundary line with a vibration displacement by frequency bands in excess of that indicated in the table below.

Frequency (cycles per second) Vibration Displacement (inches)
Steady State Impact
Under 10 0.0005 0.0010
10—19 0.0004 0.0008
20—29 0.0003 0.0006
30—39 0.0002 0.0004
40 and over 0.0001 0.0002

 

Section 13.6 - Smoke.

For the purpose of determining smoke units, the Ringelmann Chart shall be employed (BMI 6888). Each reading (Ringelmann number) shall be multiplied by the time in minutes for which it was observed, and the products added together to give the total number of smoke units observed during the total period of observation. This total shall then be converted into units per hour. In the M-1 and M-2 districts, the emission of more than ten smoke units per hour per stack, and smoke with a density in excess of Ringelmann no. 2 is prohibited except as indicated below. For special operations, the following limitations apply:

MAXIMUM FREQUENCY AND PERMITTED SMOKE UNITS AND DENSITIES FOR SPECIAL OPERATIONS

Maximum frequency permitted:

(a)

For rebuilding fires within 24-hour period: once.

(b)

For banking or cleaning fires, soot blowing, or process purging: once in six hours

Maximum smoke units permitted per hour per stack during special operations:

Ringelmann No. 1 .....20

Ringelmann No. 2 .....10

Ringelmann No. 3 .....3

Section 13.7 - Odor.

No odor shall be permitted at any lot line exceeding the lowest amount set forth in the table III, "Odor Thresholds" of chapter 5 APAM. For compounds not described in the table, odor thresholds shall be established as described in chapter 5 of APAM, and no odor shall be permitted at any lot line exceeding the amount determined by such method.

Section 13.8 - Toxic or noxious matter.

Concentration of toxic or noxious odors shall not exceed, at any point on or beyond any lot line, one-tenth of the maximum allowable concentration set forth in section 12-29 of ICR12 measured with the ADI.

Section 13.9 - Radiation.

No operation whether or not licensed by the Nuclear Regulatory Commission, shall be conducted, which exceeds the standards set forth in CFR 10.

Section 13.10 - Fire and explosive hazards.

(a)

Storage and utilization of solid materials or products which are incombustible or which in themselves support combustion and are consumed slowly as they burn is permitted.

(b)

Storage, utilization or manufacture of solid materials or products including free burning and intense burning is permitted provided that said materials or products shall be stored, utilized or manufactured within completely enclosed buildings having incombustible walls and protected throughout by an automatic fire extinguishing system.
