     A.  To use the Table, select the process weight per hour as is defined in Subsection 2.36.  Locate 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; for example, 1,500  lbs. by 3 giving a process weight per hour of 500 lbs.  The table shows that A may not discharge more than 1.77 lbs. 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 shall be interpolated.

     B.  For purposes of this regulation, the total process weight from all similar process units at a plant or premises shall be used for determining the maximum allowable emission of particulate matter that passes through a stack or stacks.  The process weight rate shall be the equipment manufacturer's or designer's guaranteed maximum input, whichever is greater.  Where the nature of any process or operation or the design of any equipment is such as to permit more than one interpretation of this definition, the interpretation that results in the minimum value for allowable emission shall apply.

9.02   Cement Kilns.  No person operating or utilizing cement kilns shall permit, cause, suffer or allow particulate matter emissions in excess of 230 mg/m^3 of exhaust gas.

9.03   Gypsum Cookers.  Subsection 9.01 shall not apply to gypsum cookers of kettles constructed prior to the effective date of these regulations.  No person shall cause or allow the emission of particulate matter into the atmosphere in any one hour from gypsum cookers or kettles constructed prior to the effective date of these regulations in total amounts which exceed 690 mg/m^3 of exhaust gas.

9.04   Asphaltic Batch Plants.  Subsection 9.01 shall not apply to an asphaltic batch plant.  No person shall cause or allow the emission of particulate matter into the atmosphere in any one hour from any or all operations of an asphaltic batch plant in total quantities in excess of the amount shown on the following table:
 

For a process weight between any two consecutive process weights in the table, the emission limitation shall be determined by interpolation.  Where the plant has more than one emission point, the emission total is that from all emission points.

No plant shall operate without a fugitive dust control system and the system shall operate and be maintained so that particulate emission is limited to the stack outlet.

9.05   Measurement.  For purposes of Section 9, any measurement of emissions into the atmosphere may be made by comparing the weight of materials before and after processing or by measurements taken after particulate emissions have passed through air pollution control devices or apparatus, if any, or by other reasonably accurate methods or procedures.

9.06   Fugitive Dust.  No person shall operate process equipment which emits fugitive dust into the atmosphere unless reasonable effective precautions are taken to prevent fugitive dust from being emitted into the atmosphere.
