Whenever the person responsible for the discharge of solid particles
believes that a specific compound of an element listed in either
Section 2.4(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.

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.

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.

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.

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.

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.

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.

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

Step 4

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 Emission for Coarse
Solid Particles.

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

Step 5

Step 6.

Step 7

Draw a horizontal line across chart from the value
determined by Step 3 to the point where this line
intersects the line determined by Step 4.

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.

Multiply the basic emission by the effect factor assigned under Section 2.4. The result yields the allowable emission for coarse solid particles.

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

Step 1

Step 2

Step 3

Step 4

Step 5

Step 6

Step 7

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

Determine distance from the stack to nearest property line.

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 Emission for Fine
Solid Particles.

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

Draw a horizontal line across chart from the value determined by Step 3 to the point where this line intersects the line determined by Step 4.

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.

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

Note:

Coarse solid particles are defined as solid particles having a size equal to or greater than 44 microns and solid particles when such particles are contained in or on liquid particles.

Fine solid particles are defined as solid particles, including fumes, having a size less than 44 microns.
