                            INTRODUCTION





     This compilation contains selected sections of many emission control



regulations and ordinances.  It has been prepared to provide state and



local air pollution control agencies, industries, and other interested



people with selected examples of the many types of regulations and



ordinances in use today.  All sections of regulations and ordinances



included have been copied directly from the original text of individual



state and local lavs.



     The regulations and ordinances have been arranged in such a manner



that each section of this report is a compilation of laws pertaining to



a specific type of pollutant or pollutant source.  These sections include



Stoke Emissions and Equivalent Opacity Regulations, Regulations Pertaining



to Particulate anisalons from Fuel Burning Plants, Regulations Pertaining



to Particulate Emissions from Refuse-Burning Equipment, Regulations



Pertaining to Particulate Emissions from Manufacturing Processes, Regulations



Pertaining to Sulfur Compound Mission Control, Regulations Pertaining



to Hydrocarbon Emission Control, Regulations Pertaining to Fluoride



Emission Control, Regulations Pertaining to Motor Vehicle Emission Control,



Regulations Pertaining to Odor Omission Control, and Zoning Ordinances.



     The regulations and ordinances compiled were selected to represent



the different methods of controlling emissions by law and to represent



varying degrees of control.



     The definitions used were for the most part taken directly from



existing regulations and ordinances.  Some were picked selectively to provide



what we feel are very good definitions while others were picked because of



their wide use by many states and communities.

 Supplemental  Regulations

 Section  2.4

      Regulation No. 1  DESIGN AND OPERATING EMISSION LIMITA'TTONS

       This Regulation clarifies the intent of Section 2.kA for those
 cases where both design and operating emission limitations are stipulated
 for a given operation.

       The design emission standard shall be met when the system is
 field operated as close to design conditions as is reasonably feasible.
 In addition, before a permit is issued for the installation of a
 collector sufficient data will be required to be submitted to the Depart-
 ment  in  the form of tests, drawings, calculations, etc., to •Drove that
 when  the collector is operated at design conditions the particulate loading
 will  not exceed the design emission limitation.

       The operating emission limitation is less stringent than the
 design emission limitation and recognizes that field operating conditions
 do not always meet design conditions and that this could cause a temporary
 degradation in over-all equipment performance.  The more lenient operating
 emission standard shall not be used as a basis for design.  It also
 shall not be used as a basis for reducing design collector efficiency
 to effectuate savings in operating cost.

 Section  4.9

      Regulation No. 1  COLLECTOR REQUIREMENT FOR SINGLE RETORT STOKER-
                                  FIRED BOILERS

       New forced draft solid fuel fired boilers of less than 400 H. P.
nominal  rating and existing boilers in this category when stack or
breeching Is replaced shall be provided with a low draft loss collector
or drop out box approved by the Bureau.

     Explanation

       While the proposed emission limitations of Section 2.4 would
       quite possibly make this requirement necessary it is  felt that
       the above statement would simplify permit issuance and reduce
       the large amount of stack sampling that could be  Involved If
       emission limitations were the  only requirement.   It is
       intended to apply primarily to new single retort  underfeed
       stoker fired plants and existing  Installations where  practical.

Division J.  INCINERATORS

       Sec. 2509-8.  INCINERATOR MAINTENANCE AND OPERATION.

       It shall be unlawful for any person to permit or cause foul
or offensive odors, fumes, gases, fly ash or smoke in the maintenance
or operation of an incinerator.

       Odors shall be considered offensive when any odor similar to
that of burning paper, garbage, or other cellulose material is emitted
from the incinerator chimney and is detectable at a distance of more
than 25 feet from the incinerator chimney or at a location of a
citizen complaint whichever is a greater distance.

       Exception:  One period of not to exceed ten (10) minutes In
any consecutive 24 hour period will be permitted for the purpose of
bringing the incinerator up to the required discharge gas temperature.

       Fly ash shall be considered offensive when the particulate
matter In the combustion gases discharged from the chimney or at any
convenient measuring point In the chimney or in the chimney connection
from the Incinerator to the chimney exceeds either criteria A or
criteria B of this section.

       Criteria A;  A pounds of particulate matter per 1000 pounds
of discharged gases adjusted to 12 per cent COp.

       Criteria B:  A discharge from the incinerator chimney of 500,000
particles per minute for incinerators located in residence districts;
750,000 particles per minute for incinerators located in business
districts; and 1,000,000 particles per minute for Incinerators located
In industrial districts.

       The method of determining criteria A shall be by approved stack
testing procedure.

       The method of determining criteria B, the number of particles
discharged from the incinerator chimney, shall be the "adhesive surface
method" and the procedure shall be as follows:  Two-inch white strips
of approved adhesive material shall be wrapped around a suitable
holder approximately 2 3/4 inch in diameter and inserted in the discharge


                                 -35-

-------
gases at the chimney exit point or at any convenient measuring point
in the chimney or beechlng.  The exposure of the adhesive surface
to the discharge gases shall be for one minute or less.  After
exposure, the adhesive surface shall be removed to the laboratory.
Approximately one square Inch of adhesive surface having the greatest
particle deposit shall be counted by approved microscope counting
techniques using magnification of lUX and the average count of 10
random fields.  "Particles caught per square inch of adhesive surface
per minute" of exposure time are thus determined.  "Particles per
minute discharged per test" are determined by multiplying the"partlcles
caught per square inch of adhesive surface per minute" times square
Inches of the chimney or breeching at the sampling point.

       For purposes of criteria B, the number of  particles discharged
shall be the average of three consecutive tests taken not less than
five minutes nor more than ten minutes separated in time from each other.
Hie choice as to which set of three consecutive tests are used shall
be at the discretion of the Air Pollution Control and Heating Engineer,
and are intended to represent a period of high particulate matter dis-
charge from the chimney.

reduction of particulate matter concentration, based on source gas volume,
below the concentration specified in the following Table for such volume;
provided, that, for the purposes of this section, the person responsible for
the emission may elect to substitute a volume from the following Table in
which any volume of gases passing through and leaving an air pollution
abatement operation may be substituted for the source gas volume of the
source operation served by such air pollution abatement operation, pro-
vided such air pollution abatement operation emits no more than forty
percent (hQ%) of the weight of particulate matter entering thereto;
and provided further that such substituted volume shall be corrected
to standard conditions and to a moisture content no greater than that of
any gas stream entering such air pollution abatement operation, and
provided further that the burden of showing the source gas volume or other
volume substituted, therefore, including all of the factors which determine
such volume and the methods of determining and computing such volume,
shall be on the person seeking to come within the provision of this

(b)  The operating limitation allows  for  gradual  deterioration of  equip-
     ment performance during extended periods  of  continuous operation
     where it is impractical to maintain  design conditions for these
     extended periods.   (See Regulation  No. 1, Section 2.4 for further
     details on intent.)

(d)  These emission limitations  shall not apply to  electric furnaces  when
     the gas collection system needs  to be disconnected due to technical
     infeasibility, as may be encountered during  charging, refining in a
     reducing slag, and pouring.

(g)  When wet collectors  or scrubbers are utilized,  that portion of water
     vapor in the exhaust gases  which was added for collector or scrubber
     requirements shall be deleted from the total exhaust gases in calcu-
     lating the particulate emission rate.

 Section 2,kA
                           REGULATION NO. 2
       DIFFERENTIATION BETWEEN JOBBING AND PRODUCTION FOUNDRIES

       Cupolas used in a Jobbing foundry are the same as those used in a
 production foundry and will vary in size only according to the quantity
 of iron melted per hour.

       However, the cupolas in a jobbing foundry will be run intermittently
 for Just long enough at one time to pour the molds that are ready on the
 foundry floor, Job by Job.  This might be for a 2 to 4 hour period per day
 for any number of days per week.

       Whereas the production foundry cupolas will melt continuously to
 pour a succession of molds that are constantly being prepared to receive
 this continuous flow of iron.  This could become 8 hours, 16 hours, or
 2k hours per day for any number of days per week.


                           REGULATION NO. 3
             COLLECTOR REQUIREMENTS FOR PRODUCTION CUPOLAS


       The intent of the design emission limitation of 0.1#/1000# of gas
 applying to production ferrous foundry cupolas is to require the instal-
 lation of high efficiency collectors capable of collecting the fine
metallic fume typical of emissions from this source.  Presently available
 equipment suitable for this application is a well designed baghouse or a
high pressure drop Venturi scrubber of equivalent efficiency.  Other
 types of collectors will be considered on their individual merit and
upon submission of adequate proof that they are capable of achieving
 equal efficiencies.

       The operating limit of 0.25#/1000# of gas is intended to provide
only for short time unavoidable variations from design conditions and
for gradual deterioration of equipment during normal continuous operation.
Deliberate or intentional operation of equipment at less than its intended
design efficiency is considered to be a violation of this Ordinance.


                           REGULATION NO. k
            COLLECTOR REQUIREMENTS FOR JOBBING SHOP CUPOLAS

       This Regulation is for the purpose of clarifying the intent of
 the emission limitation of 0.*»#/1000# of gas applying to jobbing shop
 cupolas.
                                 -52-

-------
       High efficiency cyclone type collectors or other types of
collectors not less efficient are considered acceptable and capable of
meeting this requirement.

       Should the operation of this equipment, when properly applied,
operated and maintained and served by an adequate stack, meet all
Ordinance requirements except the applicable emission limitation, this
limitation is to be re-evaluated.

       ROLE 5*».  DUST AND FUMES.   A person shall not discharge in any
one hour from any source whatsoever dust or fumes in total quantities
In excess of the amount shown in the following table:  (see next page)

       To use the following table, take the process weight per hour
as such is defined in Rule 2(j).  Then find this figure on the table,
opposite which is the maximum number of pounds of contaminants which
may be discharged into the atmosphere in any one hour.   As an example,
if A has a process which emits contaminants into the atmosphere and
which process takes 3 hours to complete, he will divide the weight
of all materials in the specific process, in this example, 1,500 Ibs.
by 3 giving a process weight per hour of 500 Ibs.  The table shows that
A may not discharge more than 1.77 Ibs. in any one hour during the
process.  Where the process weight per hour falls between figures in
the left hand column, the exact weight of permitted discharge may be
interpolated.

                                 CHAPTER VII

                         (effective October 1, 1964)


       Section 2.  CONTROL AND PROHIBITION OF AIR POLLUTION FROM
                               SOLID PARTICLES

2.1    No person shall cause, suffer, allow or permit solid particles to
       be discharged from any stack or chimney into the outdoor atmos-
       phere in excess of the allowable emission as provided herein.

2.2    Whenever the discharge from any stack or chimney includes coarse
       solid particles which consist of a single material, the allow-
       able emission of coarse solid particles shall be the basic
       emission as determined from Section 2.15 modified by the effect
       factor for the material being discharged as determined from
       Section 2.4.

2.3    Whenever the discharge from any stack or chimney includes coarse
       solid particles which consist of two or more materials, the
       allowable emission of coarse solid particles for each material
       shall be the basic emission as determined from Section 2.15
       modified by the effect factor for the respective material as
       determined from Section 2.4; and the allowable emission of
       coarse solid particles for the combined materials from such
       stack or chimney shall be either the sum of the allowable emis-
       sion for the individual materials or the allowable emission
       computed for an effect factor of one (l), whichever is the
       lesser.

2.4    The effect factor for coarse solid particles is as follows:


                         Material                        Effect Factor

       (a)  All materials not specifically                   1.0
             listed hereunder.

       (b)  Elements and their compounds on the
            basis of the element contained therein.

                          (none assigned)

               When a compound (material)  contains two
               or more elements,  the effect factor of
               the element having the lowest effect
               factor shall apply.

       (c)  Specific materials.

                          (none assigned)

                             -56-

-------
2.5    Whenever the discharge from any stack or chimney includes fine
       solid particles which consist of a single material,  the allow-
       able emission of fine solid particles shall be the basic emission
       determined from Section 2.16 modified by the effect  factor for
       the material being discharged as determined from Section 2.7.

2.6    Whenever the discharge from any stack or chimney includes fine
       solid particles which consist of two or more materials, the
       allowable emission of fine solid particles for each  material shall
       be the basic emission as determined from Section 2.16 modified
       by the effect factor for the respective material as  determined
       from Section 2.7 and the allowable emission of fine  solid particles
       for the combined materials from such stack or chimney shall be
       either the sum of the allowable emissions for the individual
       materials or the allowable emission computed for an  effect factor
       of one (l), whichever is the lesser.

2.7    The effect factor for fine solid particles is as follows:

2.8    Whenever the person responsible for the discha--ee of solid particles
       believes that a specific compound of an element listed in either
       Section 2.1*(b) or Section 2.7(b) does not contribute to air pollu-
       tion to the degree represented by the assigned effect factor, he
       •may submit data to the Department setting forth reasons and Justi-
       fication for a less restrictive effect factor for the specific
       compound in question.  If the change is approved by the Department,
       the Department shall, upon approval of the Commission, assign a
       revised effect factor which shall be used for the purpose of this
       chapter.

2.9    Whenever solid particles from one source operation are discharged
       through two or more stacks or chimneys, the total quantity that
       may be discharged from any one stack or chimney shall not exceed
       the allowable emission permitted for that stack or chimney, nor
       shall the total quantity that may be discharged from all the
       stacks exceed the emission that would be permitted from the
       single stack or chimney having the greatest allowable emission.

2.10   In any process wherein solid fuel is burned without direct contact
       with process material, Chapter V shall govern the allowable
       emission from the burning of solid fuel and Chapter VII shall
       govern the allowable emission from the source operation.

2.11   The provisions of this chapter shall not apply to:

       (a)  Smoke as defined and regulated under Chapter IV of this Code.

       (b)  Combustion of solid fuel as defined and regulated under
            Chapter V of this Code.

       (c)  Incinerators designed and operated for the destruction  of
            refuse.

                                  -58-

-------
2.12   Upon the request of the Department,  any person discharging solid
       particles through a stack or chimney shall submit to the
       Department, on forms provided by the Department, information
       regarding height of such stack, distance from stack to nearest
       property line, nature of source operation and such other infor-
       mation as the Department may require relative to the emission
       of solid particles.

2.13   Whenever the person responsible for any stack or chimney believes
       that the effective stack height is greater than the stack height,
       he may calculate the plume rise and submit his data on forms
       provided by the Department.  If the plume rise is approved by
       the Department, the effective stack height may be used in lieu of
       the stack height.

2.lU   Any person responsible for the emission of solid particles through
       a stack or chimney from source operations shall, upon request
       of the Department, provide in connection with such stack or
       chimney such sampling facilities and testing facilities, exclusive
       of instruments and sensing devices,  as may be necessary for the
       Department to determine the nature and quantity of solid particles
       which are or may be discharged as the result of source operations.
       Such facilities may be either permanent or temporary, at the
       discretion of the person responsible for their provision, and shall
       conform to all applicable laws and regulations concerning safe
       construction or safe practice.

2.15   The basic and allowable emissions for coarse solid particles shall
       be computed as follows:

       Step 1   Establish stack height or effective stack height if
                plume rise is approved.

       Step 2   Determine the distance from the stack to the nearest
                property line.

       Step 3   Divide result of Step 2 by result of Step 1, this is
                the distance from stack to nearest property line in
                stack heights.  Locate this value on the scale along
                the left side of chart for Basic Bnission for Coarse
                Solid Particles.

       Step k   Locate the line on the chart representing the stack
                height or effective stack height determined from
                Step 1; interpolate if necessary.
                                  -59-

-------
       Step 5   Draw a horizontal line across chart from the value
                determined by Step 3 to the point wherevthis line
                intersects the line determined by Step U.

       Step 6.  Draw a vertical line from the point determined by Step 5
                to the basic emission scale at the bottom of the chart.
                The point at which this line intersects the scale yields
                the basic emission in pounds per hour.

       Step 7   Multiply the basic emission by the effect factor assigned
                under Section 2.U.  The result yields the allowable
                emission for coarse solid particles.

2.16   The basic and allowable emissions for fine solid particles shall
       be computed as follows:

       Step 1   Establish stack height or effective stack height if
                plume rise is approved.

       Step 2   Determine distance from the stack to nearest property
                line.

       Step 3   Divide result of Step 2 by result of Step 1,  this is
                the distance from stack to nearest property line in
                stack heights.  Locate this value on the scale along
                the left aide of chart for Basic Bnission for Fine
                Solid Particles.

       Step U   Locate the line on the chart representing the stack
                height o? effective stack height determined from Step 1;
                interpolate if necessary.

       Step 5   Draw a horizontal line across chart from the value
                determined by Step 3 to the point where this line inter-
                sects the line determined by Step k.

       Step 6   Draw a vertical line from the point determined by Step 5
                to the basic emission scale at the bottom of the chart.
                The point at which this line intersects the scale yields
                the basic emission in pounds per hour.

       Step 7   Multiply the basic emission by the effect factor assigned
                under Section 2.7.   The result yields the allowable
                emission for fine solid particles.

Division 6, Chapter 1

       Section 6111.1   No person shall cause,  let, permit,  suffer,  or
allow any emission from any general combustion operation or general
operation which does not comply with the visible emission limitations
in section 3110, Chapter 1, Division 3.

       Section 6111.2   No person shall cause,  let, permit,  suffer,
or allow the emission from any general combustion operation of particles
in sufficient number to cause annoyance to any other person, which
particles are sufficiently large as to be visible as individual par-
ticles at the emission point or of such size and nature as to be visible
individually as incandescent particles.  This section 6111.2 shall only
apply if such particles fall on real property other than that of the
person responsible for the emission.

       Section 6112.1   No person shall cause,  let, permit,  suffer,  or
allow the emission from any general operation or general combustion
operation of particulate matter from any emission point in a concentration
in excess of 0.30 grain per standard dry cubic foot of exhaust gas volume.

       Section 6112.2   Except as provided in sections 6112.3 and 6113 no
person shall cause, let, permit, suffer, or allow the emission from any
general operation or general combustion operation of particulate matter
from any emission point at a rate in excess of that specified in Table 2
for the process weight rate allocated to such emission point.

       Section 6112.3   The limitations established by section 6112.2
shall not require the reduction of particulate matter concentration, based
on the source gas volume, below the concentration specified in Table 3
for such volume; provided that, for the purposes of this section 6112.3,
the person responsible for the emission may elect to substitute a volume
determined according to the provisions of section 6112A; and provided
further that the burden of showing the source gas volume or other volume
substituted therefore,including all of the factors which determine such
volume and the methods of determining and computing such volume, shall be
on the person seeking to come within the provisions of this section 6112.3.

                      (revised January 20, 1965)

                             CHAPTER 28-3

        28-3.03  Emission levels.  - Gaseous or vater soluble fluorides.

        (l)  In order to reduce the fluoride concentration in the atmos-
phere of the Polk-Hillsborough Air Pollution Control District, the
maximum quantity of fluorides emitted by any installation or plant shall
be determined on the following basis:

        The allowable quantity of fluoride expressed in pounds per day
shall be calculated by multiplying the unit .emission of 0.6 pound fluoride
(as F") per ton of P2^5 or equivalent times the tons of PpO* or equiv-
alent attained in the maximum sustained 24-hour production mentioned in
Section (2) below.

   (0.6 pound Fluoride (as F")      Production (Tons of PpO,. or equiv.
    Ton PpO,. or equivalent          per day) = Allowable   ^Quantity
           '                        Fluoride (ib./Day).

        The above formula shall be used to determine maximum allowable
quantity of fluorides emitted by any installation or plant.  The basis
for the above calculations shall be the phosphoric acid reactor section
production.  Where calcined or defluorinated phosphate rock is produced,
the calculations for these unit operations .only shall be based on the
PpOc equivalent produced.

        (2)  Each person shall, within thirty (30) days after the effec-
tive date of these regulations, notify the Board in writing of the
maximum -sustained twenty-four (24) hour production capacity achieved in
his phosphoric acid manufacturing., calcination and/or defluorination
facilities prior to May 1, 1964.  The maximum allowable quantity cal-
culated by the formula provided in 28-3.03 (l),  supra, shall constitute
the total quantity of gaseous and/or water soluble fluorides which may
be emitted by each installation or plant,  except in those cases of
specific trade products commonly known as  normal phosphate, superphosphate
or normal superphosphate operation shall not emit gaseous and/or water
soluble fluorides (F~) in excess of thirty (30)  pounds per operating day.

        (3)  Within thirty (30) days after receipt of the maximum
sustained twenty-four (24) hour production capacity information,  the Board
                                 -90-

-------
shall notify each person in writing of the maximum allowable total
fluoride emissions that will be permitted such person.

        (4)  The maximum allowable fluoride emission as assigned above
shall be attained not later than one year by an installation or plant
In existence on the effective date of these rules, after receipt of
assignment from the board.

        (5)  The Board may require, from time to time, Information
concerning points of emission and quantities of fluorides anticipated
to be released therefrom.

        (6)  Any material fed to or product made from fluoride-bearing
compounds not Included in these regulations shall be assigned an
emission limit consistent with 28-3.03(1) and 28-3.03(2)(a) and/or
the chemical, physical and environmental conditions prevailing at the
time.

        (7)  Compliance with the above emission standards shall be
ascertained by means of source sampling; the Board may do ambient air
sampling, filter paper, vegetative, or other recognized methods of
sampling to provide such supplemental information as it may desire to
verify source sampling and/or to determine conditions existing within
the Polk-Hillsborough Air Pollution Control District.

or add to any existing installation or plant emitting gaseous or water
soluble fluorides unless it can be demonstrated to the satisfaction of
the Board that such alterations or additions will not increase the
total fluoride output above the maximum daily emission figure furnished
them by the Board.

through its operation, may emit air contaminants, until a maximum allow-
able daily emission level of air contaminants has been assigned and a
permit to construct has been obtained from the Board.  The unit emissions,
expressed as pounds of fluoride per ton of Pp05 or equivalent, and which
shall not exceed 0.4 (four-tenths) pounds shall be developed by the
Board, taking into consideration the following:

         Some hydrocarbons, for example methane, ethane, propane,
n-butane and acetylene, are not considered sufficiently reactive
to produce photochemical smog effects.  The Department is working on
methods which measure the reactive organic compounds in exhaust and
will restate the hydrocarbon standard in terms of reactive hydrocarbons
when methods and data satisfactory to the Department are developed.
         If other test cycles are used, they must represent urban driv-
ing and the emissions must be relatable to the composite Pample from
the driving modes described in Table I.

         The standard refers to emissions in a 24-hour day when the mini-
mum temperature is 60° F.  and the maximum is 90° F., and when the fuel
tank Is between one-fourth and one-half full, averaging three-eighths
full.  The standard was developed from data obtained when fuels averag-
ing a Reid Vapor Pressure of approximately 9 were used, and when hydro-
carbon emissions were collected in condensing traps at dry ice
temperature.  Equivalent methods and other conditions may be used if
approved by the Department of Public Health.


       30560.  Carburetor Hot Soak Emissions.  The standard for
carburetor hot soak emissions is:

                   Hydrocarbon - 2 grams per soak


        The standard refers to emissions from the carburetor of an
automotive engine operated to an equilibrium coolant temperature of
180° F. minimum and when the ambient air temperature is from 85 to
95° F. minimum.  The soak duration is one hour.  The standard was
developed from data obtained when fuels averaging a Reid Vapor Pressure
of approximately 9 were used in the test vehicles, and when hydrocarbon
emissions were collected In condensing traps at dry ice temperature.
Equivalent methods and other conditions may be used if approved by the
Department of Public Health.

(Note:  Sections 30550 and 30560 shall become effective January 1, 1970,
at which time the State shall accept control devices for approval
procedures.)

        Any use established in a Manufacturing District  shall be so
 operated  as  to comply with the performance standards governing smoke
 and particu.late matter set forth hereinafter for the district in which
 such use  shh.ll be located.  No use already established on the effective
 date of this ordinance shall be so altered or modified as to conflict with, or
 further conflict with, the performance standards governing smoke and
 particulate matter established hereinafter for the district in which such
 use is  located.

        In addition to the  performance standards specified hereinafter,
 the emission of smoke or particulate matter in such manner or quantity
 as  to endanger or to be detrimental to the public health, safety, com-
 fort, or  welfare is hereby declared to be a public nuisance and shall
 henceforth be unlawful.

        For the purpose of  grading the density of smoke the Ringelmann
 Chart published and used by the United States Bureau of Mines shall be
 employed.  The emission of  smoke or particulate matter of a density
 greater than No. 2 on the  Ringelmann Chart is prohibited at all times
 except  as  otherwise provided hereinafter.

        The emission, from all sources within any lot area, of particulate
matter  containing more than ten percent by weight of particles having a
 particle  diameter larger than kk microns is prohibited.

        Dust and other types of air pollution, borne by the wind from
 such sources as storage areas,  yards,  roads and the like within lot
boundaries, shall be kept to a minimum by appropriate landscaping,
paving, oiling, fencing,  or acceptable means.  Emission of particulate
matter from such sources  in excess of the weight limitations specified
hereinafter is prohibited.

 SECTION 17
 A.  A Light Industrial Use IB one which creates a minimum amount of
 nuisance outside the plant; is conducted entirely within enclosed buildings,
 does  not use the open area around such buildings for storage of raw
 materials or manufactured products or for any other industrial purpose
 other than transporting goods between buildings; provides for enclosed
 loading and unloading facilities; and such use conforms to the following
 performance standards.

       1.  Smoke - The emission of more than ten (10) smoke units per
 hour  per stack and emissions in excess of Ringelmann No. 2 are prohibited.
 However, once during any 24 hour period for soot blowing, process purging
 and fire cleaning, each stack shall be permitted an additional ten (10)
 ouoke units, during which time smoke up to and including Ringelmann No.3
 is permitted.

       2.  Particulate Matter - The rate of emission of particulate
 matter from all sources within the boundaries of any lot shall not
 exceed a net figure of one pound per hour per acre, of which no more
 than  ten percent (10$) by weight of particles larger than kk microns
 (325  mesh; shall be allowed.  Determination of the total net rate of
 emission shall be made as follows:

           a.  Determine the maximum emission in pounds per hour from
           each source of emission and divide this figure by the number
           of acres of lot area - thus obtaining a gross hourly emission
           rate per acre.

           b.  Deduct from the gross rate derived above, the appropriate
           correction factors for height of stack and stack velocity as
           listed in Tables I and II, thus obtaining the net rate of
           emission in pounds per hour per acre of each source.

           c.  Add together the individual rates of emission derived
           above of each source to obtain the total net rate of emission
           from all sources within the boundaries of the lot.  Dust and
           other types of air pollution, borne by the wind from such
           sources as storage areas,  yards, roads and the like within
           lot boundaries, shall be kept to a minimum by appropriate
           landscaping, paving, oiling, fencing, or other acceptable
           means >

       3-  Odor -  No activity or operation shall permit odors to be
released which shall be detectable at the lot line.

        4.   Toxic and noxious materials - The emission of toxic and
 noxious materials  shall not exceed the quantities determined by the
 following  formula:
                                  p
                         Q = 36 Cx       where

            Q is the  maximum permitted quantity of toxic material emitted
            in the  four  hour period having the greatest average concen-
            tration (cubic feet);  C is the threshold limit value for
            toxic materials in industry (parts per million by volume)
            as set  forth in "Threshold Limit Values for Toxic Materials
            in Industry", 1955, issued by the Indiana State Board of
            Health, Division of Industrial Hygiene;
            x is the  nearest distance in thousands of feet of the stack,
            vent, flue or other discharge point to a Residence or
            Business  District boundary line ( ft.  ).

            When C  is given as milligrams per cubic meter, multiply
            this figure  by O.o6l, place it in the above formula and
            obtain Q  in  pounds  permitted in four hours.  If the
            material  is  emitted from open piles, ponds, tanks, areas,
            etc . the  maximum permitted concentration measured at a
            Residence District boundary line shall be 10 per cent of
            the threshold limit value C.

B.  A General Industrial Use is one which requires both buildings and open
area for manufacturing., fabricating, processing, extraction, heavy repair-
ing, dismantling, storage or disposal of equipment,  raw materials,
manufactured products or wastes, and land and/or buildings in this District
shall be used so as  to comply to the following performance standards.
       1.  Stroke - 3he emission of more than thirty (30) smoke units per
hour per stack and emissions in excess of Ringelmann No. 2 are prohibited.
However, once during any six hour period, for soot blowing, process
purging and fire cleaning, each stack shall be permitted an additional
ten (10) smoke units, daring which time smoke up to and including
Ringelmann No. 3 is permitted.
                                  -118-

-------
       2.  Articulate Matter - The rate of emission of particulate
natter from all sources within the boundaries of any lot shall not
exceed a net figure of three pounds per hour per acre, of vhich no
more than ten per cent (105&) by weight of particles larger than Mf
microns (325 Mesh) shall be allowed.  Determination of the total
net rate of emission shall be made as follows:

           a.  Determine the maximum emission in pounds per hour from
           each source of emission and divide this figure by the
           number of acres of lot area - thus obtaining a gross hourly
           emission rate per acre.

           b.  Deduct from the gross rate derived above, the appro-
           priate correction factors for height of stack and stack
           velocity as listed in Tables IV and V, thus obtaining the
           net rate of emission in pounds per hour per acre of each
           source.

           c.  Aid together the individual rates of emission derived
           above of each source to obtain the total net rate of emission
           from all sources within the boundaries of the lot.  Dust
           and other types of air pollution, borne by the wind from
           each sources as storage areas, yards, roads and the like
           within lot boundaries, shall be kept to a minimum by
           appropriate landscaping, paving, oiling, fencing or other
           acceptable means.  Emission of particulate matter from
           such sources in excess of the weight limitations specified
           herein is prohibited.

       3.  Odor - No activity or operation shall permit odors to be
released which shall be detectable at any Residence District boundary
line.  In addition, such odor, when measured at the lot line, shall
be rendered undetectable by mixing one volume of the odorous air with
four volumes of clean air.

       U.  Toxic and noxious materials - The emission of toxic and
noxious materials shall not exceed the quantities determined by the
following formula:

                           Q = 90 Cx2      where

           Q is the maximum permitted quantity of toxic material
           emitted in the four hour period having  the greatest
           average concentration (cubic feet).
           C is the threshold limit value for toxic materials in
           industry (parts per million by volume) as set forth in
           "Threshold Limit Values for Toxic Materials in Industry",
           1955, issued by the Indiana State Board of Health, Division
           of Industrial Hygiene.

C.  A Heavy Industrial Use is one which requires both buildings and open
area for manufacturing, fabricating, processing, extraction, heavy
repairing, dismantling, storage or disposal of equipment, raw materials,
manufactured products or wastes and one which will comply with the
following performance standards.

       1.  Smoke - The average emission of more than ninety (90) smoke
units per hour per stack, for all smoke stacks on the lot, and emission
of smoke in excess of Ringelmann No. 3 are prohibited.  However, this
restriction shall not apply to fire building, soot blowing, process
purging and fire cleaning which will be permitted once during any two
hour period, except that where there are more than ten (10) smoke
stacks on a lot, this provision will apply to not more than twenty (20)
per cent of such stacks at any one time.

       2.  Earticulflte Matter - The rate of emission of particulate
matter from all sources within the boundaries of any, lot shall not
exceed a net figure of six (6) pounds per hour per acre, of which no
more than sixty (60) per cent by weight of particles larger than 44
microns (325 mesh) shall be allowed.  Determination of the total net
rate of emission shall be made as follows:

           a.  Determine the emission in pounds per hour from each
           source of emission and divide this figure by the number
           of acres of lot area - thus obtaining a gross hourly emission
           rate per acre.
                                   -121-

-------
           b.  Deduct from the gross rate derived above, the appro-
           priate correction factors for height of stack and stack
           velocity as listed in Tables VII and VIII, thus obtaining
           the net rate of emission in pounds per hour per acre of
           each source.

           c.  Add together the individual rates of emission derived
           above of each source to ottain the total net rate of emission
           from all sources within the boundaries of the lot.  Dust
           and other types of air pollution, borne by wind from such
           sources as storage areas, yards, roads and the like within
           lot boundaries, shall be kept to a minimum by appropriate
           landscaping, paving, .oiling, fencing or other acceptable
           means.  Emission of particulate matter from such sources
           in excess of the weight limitations specified herein is
           prohibited.

       3-  Odor - No activity or operation shall permit odors to be
released which shall create a nuisance at a Residence District boundary.

       U.  Toxic and noxious material - The emission of toxic and
noxious materials shall not produce concentrations exceeding 30$ of
the threshold limit value for toxic materials in industry (parts per
million by volume) as set forth in "Threshold Limit Values for Toxic
Materials in Industry", 1955 > issued by the Indiana State Board of
Health, Division of Industrial Hygiene, at a Residence or Business
District boundary.
